Podcasts about hdr high dynamic range

Dans cet épisode, Emmanuel et Antonio discutent de divers sujets liés au développement: Applets (et oui), app iOS développées sous Linux, le protocole A2A, l'accessibilité, les assistants de code AI en ligne de commande (vous n'y échapperez pas)… Mais aussi des approches méthodologiques et architecturales comme l'architecture hexagonale, les tech radars, l'expert généraliste et bien d'autres choses encore.

News Langages Les Applets Java c'est terminé pour de bon… enfin, bientot: https://openjdk.org/jeps/504 Les navigateurs web ne supportent plus les applets. L'API Applet et l'outil appletviewer ont été dépréciés dans JDK 9 (2017). L'outil appletviewer a été supprimé dans JDK 11 (2018). Depuis, impossible d'exécuter des applets avec le JDK. L'API Applet a été marquée pour suppression dans JDK 17 (2021). Le Security Manager, essentiel pour exécuter des applets de façon sécurisée, a été désactivé définitivement dans JDK 24 (2025). Librairies Quarkus 3.24 avec la notion d'extensions qui peuvent fournir des capacités à des assistants https://quarkus.io/blog/quarkus-3-24-released/ les assistants typiquement IA, ont accès a des capacités des extensions Par exemple générer un client à partir d'openAPI Offrir un accès à la,base de données en dev via le schéma. L'intégration d'Hibernate 7 dans Quarkus https://quarkus.io/blog/hibernate7-on-quarkus/ Jakarta data api restriction nouvelle Injection du SchemaManager Sortie de Micronaut 4.9 https://micronaut.io/2025/06/30/micronaut-framework-4-9-0-released/ Core : Mise à jour vers Netty 4.2.2 (attention, peut affecter les perfs). Nouveau mode expérimental “Event loop Carrier” pour exécuter des virtual threads sur l'event loop Netty. Nouvelle annotation @ClassImport pour traiter des classes déjà compilées. Arrivée des @Mixin (Java uniquement) pour modifier les métadonnées d'annotations Micronaut sans altérer les classes originales. HTTP/3 : Changement de dépendance pour le support expérimental. Graceful Shutdown : Nouvelle API pour un arrêt en douceur des applications. Cache Control : API fluente pour construire facilement l'en-tête HTTP Cache-Control. KSP 2 : Support de KSP 2 (à partir de 2.0.2) et testé avec Kotlin 2. Jakarta Data : Implémentation de la spécification Jakarta Data 1.0. gRPC : Support du JSON pour envoyer des messages sérialisés via un POST HTTP. ProjectGen : Nouveau module expérimental pour générer des projets JVM (Gradle ou Maven) via une API. Un super article sur experimenter avec les event loops reactives dans les virtualthreads https://micronaut.io/2025/06/30/transitioning-to-virtual-threads-using-the-micronaut-loom-carrier/ Malheureusement cela demander le hacker le JDK C'est un article de micronaut mais le travail a ete collaboratif avec les equipes de Red Hat OpenJDK, Red Hat perf et de Quarkus et Vert.x Pour les curieux c'est un bon article Ubuntu offre un outil de creation de container pour Spring notamment https://canonical.com/blog/spring-boot-containers-made-easy creer des images OCI pour les applications Spring Boot basées sur Ubuntu base images bien sur utilise jlink pour reduire la taille pas sur de voir le gros avantage vs d'autres solutions plus portables d'ailleurs Canonical entre dans la danse des builds d'openjdk Le SDK Java de A2A contribué par Red Hat est sorti https://quarkus.io/blog/a2a-project-launches-java-sdk/ A2A est un protocole initié par Google et donne à la fondation Linux Il permet à des agents de se décrire et d'interagir entre eux Agent cards, skills, tâche, contexte A2A complémente MCP Red hat a implémenté le SDK Java avec le conseil des équipes Google En quelques annotations et classes on a un agent card, un client A2A et un serveur avec l'échange de messages via le protocole A2A Comment configurer mockito sans warning après java 21 https://rieckpil.de/how-to-configure-mockito-agent-for-java-21-without-warning/ les agents chargés dynamiquement sont déconseillés et seront interdis bientôt Un des usages est mockito via bytebuddy L'avantage est que la,configuration était transparente Mais bon sécurité oblige c'est fini. Donc l'article décrit comment configurer maven gradle pour mettre l'agent au démarrage des tests Et aussi comment configurer cela dans IntelliJ idea. Moins simple malheureusement Web Des raisons “égoïstes” de rendre les UIs plus accessibles https://nolanlawson.com/2025/06/16/selfish-reasons-for-building-accessible-uis/ Raisons égoïstes : Des avantages personnels pour les développeurs de créer des interfaces utilisateurs (UI) accessibles, au-delà des arguments moraux. Débogage facilité : Une interface accessible, avec une structure sémantique claire, est plus facile à déboguer qu'un code désordonné (la « soupe de div »). Noms standardisés : L'accessibilité fournit un vocabulaire standard (par exemple, les directives WAI-ARIA) pour nommer les composants d'interface, ce qui aide à la clarté et à la structuration du code. Tests simplifiés : Il est plus simple d'écrire des tests automatisés pour des éléments d'interface accessibles, car ils peuvent être ciblés de manière plus fiable et sémantique. Après 20 ans de stagnation, la spécification du format d'image PNG évolue enfin ! https://www.programmax.net/articles/png-is-back/ Objectif : Maintenir la pertinence et la compétitivité du format. Recommandation : Soutenu par des institutions comme la Bibliothèque du Congrès américain. Nouveautés Clés :Prise en charge du HDR (High Dynamic Range) pour une plus grande gamme de couleurs. Reconnaissance officielle des PNG animés (APNG). Support des métadonnées Exif (copyright, géolocalisation, etc.). Support Actuel : Déjà intégré dans Chrome, Safari, Firefox, iOS, macOS et Photoshop. Futur :Prochaine édition : focus sur l'interopérabilité entre HDR et SDR. Édition suivante : améliorations de la compression. Avec le projet open source Xtool, on peut maintenant construire des applications iOS sur Linux ou Windows, sans avoir besoin d'avoir obligatoirement un Mac https://xtool.sh/tutorials/xtool/ Un tutoriel très bien fait explique comment faire : Création d'un nouveau projet via la commande xtool new. Génération d'un package Swift avec des fichiers clés comme Package.swift et xtool.yml. Build et exécution de l'app sur un appareil iOS avec xtool dev. Connexion de l'appareil en USB, gestion du jumelage et du Mode Développeur. xtool gère automatiquement les certificats, profils de provisionnement et la signature de l'app. Modification du code de l'interface utilisateur (ex: ContentView.swift). Reconstruction et réinstallation rapide de l'app mise à jour avec xtool dev. xtool est basé sur VSCode sur la partie IDE Data et Intelligence Artificielle Nouvelle edition du best seller mondial “Understanding LangChain4j” : https://www.linkedin.com/posts/agoncal_langchain4j-java-ai-activity-7342825482830200833-rtw8/ Mise a jour des APIs (de LC4j 0.35 a 1.1.0) Nouveaux Chapitres sur MCP / Easy RAG / JSon Response Nouveaux modeles (GitHub Model, DeepSeek, Foundry Local) Mise a jour des modeles existants (GPT-4.1, Claude 3.7…) Google donne A2A a la Foundation Linux https://developers.googleblog.com/en/google-cloud-donates-a2a-to-linux-foundation/ Annonce du projet Agent2Agent (A2A) : Lors du sommet Open Source Summit North America, la Linux Foundation a annoncé la création du projet Agent2Agent, en partenariat avec Google, AWS, Microsoft, Cisco, Salesforce, SAP et ServiceNow. Objectif du protocole A2A : Ce protocole vise à établir une norme ouverte pour permettre aux agents d'intelligence artificielle (IA) de communiquer, collaborer et coordonner des tâches complexes entre eux, indépendamment de leur fournisseur. Transfert de Google à la communauté open source : Google a transféré la spécification du protocole A2A, les SDK associés et les outils de développement à la Linux Foundation pour garantir une gouvernance neutre et communautaire. Soutien de l'industrie : Plus de 100 entreprises soutiennent déjà le protocole. AWS et Cisco sont les derniers à l'avoir validé. Chaque entreprise partenaire a souligné l'importance de l'interopérabilité et de la collaboration ouverte pour l'avenir de l'IA. Objectifs de la fondation A2A : Établir une norme universelle pour l'interopérabilité des agents IA. Favoriser un écosystème mondial de développeurs et d'innovateurs. Garantir une gouvernance neutre et ouverte. Accélérer l'innovation sécurisée et collaborative. parler de la spec et surement dire qu'on aura l'occasion d'y revenir Gemini CLI :https://blog.google/technology/developers/introducing-gemini-cli-open-source-ai-agent/ Agent IA dans le terminal : Gemini CLI permet d'utiliser l'IA Gemini directement depuis le terminal. Gratuit avec compte Google : Accès à Gemini 2.5 Pro avec des limites généreuses. Fonctionnalités puissantes : Génère du code, exécute des commandes, automatise des tâches. Open source : Personnalisable et extensible par la communauté. Complément de Code Assist : Fonctionne aussi avec les IDE comme VS Code. Au lieu de blocker les IAs sur vos sites vous pouvez peut-être les guider avec les fichiers LLMs.txt https://llmstxt.org/ Exemples du projet angular: llms.txt un simple index avec des liens : https://angular.dev/llms.txt lllms-full.txt une version bien plus détaillée : https://angular.dev/llms-full.txt Outillage Les commits dans Git sont immuables, mais saviez vous que vous pouviez rajouter / mettre à jour des “notes” sur les commits ? https://tylercipriani.com/blog/2022/11/19/git-notes-gits-coolest-most-unloved-feature/ Fonctionnalité méconnue : git notes est une fonctionnalité puissante mais peu utilisée de Git. Ajout de métadonnées : Permet d'attacher des informations à des commits existants sans en modifier le hash. Cas d'usage : Idéal pour ajouter des données issues de systèmes automatisés (builds, tickets, etc.). Revue de code distribuée : Des outils comme git-appraise ont été construits sur git notes pour permettre une revue de code entièrement distribuée, indépendante des forges (GitHub, GitLab). Peu populaire : Son interface complexe et le manque de support des plateformes de forge ont limité son adoption (GitHub n'affiche même pas/plus les notes). Indépendance des forges : git notes offre une voie vers une plus grande indépendance vis-à-vis des plateformes centralisées, en distribuant l'historique du projet avec le code lui-même. Un aperçu dur Spring Boot debugger dans IntelliJ idea ultimate https://blog.jetbrains.com/idea/2025/06/demystifying-spring-boot-with-spring-debugger/ montre cet outil qui donne du contexte spécifique à Spring comme les beans non activés, ceux mockés, la valeur des configs, l'état des transactions Il permet de visualiser tous les beans Spring directement dans la vue projet, avec les beans non instanciés grisés et les beans mockés marqués en orange pour les tests Il résout le problème de résolution des propriétés en affichant la valeur effective en temps réel dans les fichiers properties et yaml, avec la source exacte des valeurs surchargées Il affiche des indicateurs visuels pour les méthodes exécutées dans des transactions actives, avec les détails complets de la transaction et une hiérarchie visuelle pour les transactions imbriquées Il détecte automatiquement toutes les connexions DataSource actives et les intègre avec la fenêtre d'outils Database d'IntelliJ IDEA pour l'inspection Il permet l'auto-complétion et l'invocation de tous les beans chargés dans l'évaluateur d'expression, fonctionnant comme un REPL pour le contexte Spring Il fonctionne sans agent runtime supplémentaire en utilisant des breakpoints non-suspendus dans les bibliothèques Spring Boot pour analyser les données localement Une liste communautaire sur les assistants IA pour le code, lancée par Lize Raes https://aitoolcomparator.com/ tableau comparatif qui permet de voir les différentes fonctionnalités supportées par ces outils Architecture Un article sur l'architecture hexagonale en Java https://foojay.io/today/clean-and-modular-java-a-hexagonal-architecture-approach/ article introductif mais avec exemple sur l'architecture hexagonale entre le domaine, l'application et l‘infrastructure Le domain est sans dépendance L‘appli spécifique à l'application mais sans dépendance technique explique le flow L'infrastructure aura les dépendances à vos frameworks spring, Quarkus Micronaut, Kafka etc Je suis naturellement pas fan de l'architecture hexagonale en terme de volume de code vs le gain surtout en microservices mais c'est toujours intéressant de se challenger et de regarder le bénéfice coût. Gardez un œil sur les technologies avec les tech radar https://www.sfeir.dev/cloud/tech-radar-gardez-un-oeil-sur-le-paysage-technologique/ Le Tech Radar est crucial pour la veille technologique continue et la prise de décision éclairée. Il catégorise les technologies en Adopt, Trial, Assess, Hold, selon leur maturité et pertinence. Il est recommandé de créer son propre Tech Radar pour l'adapter aux besoins spécifiques, en s'inspirant des Radars publics. Utilisez des outils de découverte (Alternativeto), de tendance (Google Trends), de gestion d'obsolescence (End-of-life.date) et d'apprentissage (roadmap.sh). Restez informé via les blogs, podcasts, newsletters (TLDR), et les réseaux sociaux/communautés (X, Slack). L'objectif est de rester compétitif et de faire des choix technologiques stratégiques. Attention à ne pas sous-estimer son coût de maintenance Méthodologies Le concept d'expert generaliste https://martinfowler.com/articles/expert-generalist.html L'industrie pousse vers une spécialisation étroite, mais les collègues les plus efficaces excellent dans plusieurs domaines à la fois Un développeur Python expérimenté peut rapidement devenir productif dans une équipe Java grâce aux concepts fondamentaux partagés L'expertise réelle comporte deux aspects : la profondeur dans un domaine et la capacité d'apprendre rapidement Les Expert Generalists développent une maîtrise durable au niveau des principes fondamentaux plutôt que des outils spécifiques La curiosité est essentielle : ils explorent les nouvelles technologies et s'assurent de comprendre les réponses au lieu de copier-coller du code La collaboration est vitale car ils savent qu'ils ne peuvent pas tout maîtriser et travaillent efficacement avec des spécialistes L'humilité les pousse à d'abord comprendre pourquoi les choses fonctionnent d'une certaine manière avant de les remettre en question Le focus client canalise leur curiosité vers ce qui aide réellement les utilisateurs à exceller dans leur travail L'industrie doit traiter “Expert Generalist” comme une compétence de première classe à nommer, évaluer et former ca me rappelle le technical staff Un article sur les métriques métier et leurs valeurs https://blog.ippon.fr/2025/07/02/monitoring-metier-comment-va-vraiment-ton-service-2/ un article de rappel sur la valeur du monitoring métier et ses valeurs Le monitoring technique traditionnel (CPU, serveurs, API) ne garantit pas que le service fonctionne correctement pour l'utilisateur final. Le monitoring métier complète le monitoring technique en se concentrant sur l'expérience réelle des utilisateurs plutôt que sur les composants isolés. Il surveille des parcours critiques concrets comme “un client peut-il finaliser sa commande ?” au lieu d'indicateurs abstraits. Les métriques métier sont directement actionnables : taux de succès, délais moyens et volumes d'erreurs permettent de prioriser les actions. C'est un outil de pilotage stratégique qui améliore la réactivité, la priorisation et le dialogue entre équipes techniques et métier. La mise en place suit 5 étapes : dashboard technique fiable, identification des parcours critiques, traduction en indicateurs, centralisation et suivi dans la durée. Une Definition of Done doit formaliser des critères objectifs avant d'instrumenter tout parcours métier. Les indicateurs mesurables incluent les points de passage réussis/échoués, les temps entre actions et le respect des règles métier. Les dashboards doivent être intégrés dans les rituels quotidiens avec un système d'alertes temps réel compréhensibles. Le dispositif doit évoluer continuellement avec les transformations produit en questionnant chaque incident pour améliorer la détection. La difficulté c'est effectivement l'évolution métier par exemple peu de commandes la nuit etc ça fait partie de la boîte à outils SRE Sécurité Toujours à la recherche du S de Sécurité dans les MCP https://www.darkreading.com/cloud-security/hundreds-mcp-servers-ai-models-abuse-rce analyse des serveurs mcp ouverts et accessibles beaucoup ne font pas de sanity check des parametres si vous les utilisez dans votre appel genAI vous vous exposer ils ne sont pas mauvais fondamentalement mais n'ont pas encore de standardisation de securite si usage local prefferer stdio ou restreindre SSE à 127.0.0.1 Loi, société et organisation Nicolas Martignole, le même qui a créé le logo des Cast Codeurs, s'interroge sur les voies possibles des développeurs face à l'impact de l'IA sur notre métier https://touilleur-express.fr/2025/06/23/ni-manager-ni-contributeur-individuel/ Évolution des carrières de développeur : L'IA transforme les parcours traditionnels (manager ou expert technique). Chef d'Orchestre d'IA : Ancien manager qui pilote des IA, définit les architectures et valide le code généré. Artisan Augmenté : Développeur utilisant l'IA comme un outil pour coder plus vite et résoudre des problèmes complexes. Philosophe du Code : Un nouveau rôle centré sur le “pourquoi” du code, la conceptualisation de systèmes et l'éthique de l'IA. Charge cognitive de validation : Nouvelle charge mentale créée par la nécessité de vérifier le travail des IA. Réflexion sur l'impact : L'article invite à choisir son impact : orchestrer, créer ou guider. Entraîner les IAs sur des livres protégés (copyright) est acceptable (fair use) mais les stocker ne l'est pas https://www.reuters.com/legal/litigation/anthropic-wins-key-ruling-ai-authors-copyright-lawsuit-2025-06-24/ Victoire pour Anthropic (jusqu'au prochain procès): L'entreprise a obtenu gain de cause dans un procès très suivi concernant l'entraînement de son IA, Claude, avec des œuvres protégées par le droit d'auteur. “Fair Use” en force : Le juge a estimé que l'utilisation des livres pour entraîner l'IA relevait du “fair use” (usage équitable) car il s'agit d'une transformation du contenu, pas d'une simple reproduction. Nuance importante : Cependant, le stockage de ces œuvres dans une “bibliothèque centrale” sans autorisation a été jugé illégal, ce qui souligne la complexité de la gestion des données pour les modèles d'IA. Luc Julia, son audition au sénat https://videos.senat.fr/video.5486945_685259f55eac4.ia–audition-de-luc-julia-concepteur-de-siri On aime ou pas on aide pas Luc Julia et sa vision de l'IA . C'est un eversion encore plus longue mais dans le même thème que sa keynote à Devoxx France 2025 ( https://www.youtube.com/watch?v=JdxjGZBtp_k ) Nature et limites de l'IA : Luc Julia a insisté sur le fait que l'intelligence artificielle est une “évolution” plutôt qu'une “révolution”. Il a rappelé qu'elle repose sur des mathématiques et n'est pas “magique”. Il a également alerté sur le manque de fiabilité des informations fournies par les IA génératives comme ChatGPT, soulignant qu'« on ne peut pas leur faire confiance » car elles peuvent se tromper et que leur pertinence diminue avec le temps. Régulation de l'IA : Il a plaidé pour une régulation “intelligente et éclairée”, qui devrait se faire a posteriori afin de ne pas freiner l'innovation. Selon lui, cette régulation doit être basée sur les faits et non sur une analyse des risques a priori. Place de la France : Luc Julia a affirmé que la France possédait des chercheurs de très haut niveau et faisait partie des meilleurs mondiaux dans le domaine de l'IA. Il a cependant soulevé le problème du financement de la recherche et de l'innovation en France. IA et Société : L'audition a traité des impacts de l'IA sur la vie privée, le monde du travail et l'éducation. Luc Julia a souligné l'importance de développer l'esprit critique, notamment chez les jeunes, pour apprendre à vérifier les informations générées par les IA. Applications concrètes et futures : Le cas de la voiture autonome a été discuté, Luc Julia expliquant les différents niveaux d'autonomie et les défis restants. Il a également affirmé que l'intelligence artificielle générale (AGI), une IA qui dépasserait l'homme dans tous les domaines, est “impossible” avec les technologies actuelles. Rubrique débutant Les weakreferences et le finalize https://dzone.com/articles/advanced-java-garbage-collection-concepts un petit rappel utile sur les pièges de la méthode finalize qui peut ne jamais être invoquée Les risques de bug si finalize ne fini jamais Finalize rend le travail du garbage collector beaucoup plus complexe et inefficace Weak references sont utiles mais leur libération n'est pas contrôlable. Donc à ne pas abuser. Il y a aussi les soft et phantom references mais les usages ne sont assez subtils et complexe en fonction du GC. Le sériel va traiter les weak avant les soft, parallel non Le g1 ça dépend de la région Z1 ça dépend car le traitement est asynchrone Conférences La liste des conférences provenant de Developers Conferences Agenda/List par Aurélie Vache et contributeurs : 14-19 juillet 2025 : DebConf25 - Brest (France) 5 septembre 2025 : JUG Summer Camp 2025 - La Rochelle (France) 12 septembre 2025 : Agile Pays Basque 2025 - Bidart (France) 18-19 septembre 2025 : API Platform Conference - Lille (France) & Online 22-24 septembre 2025 : Kernel Recipes - Paris (France) 23 septembre 2025 : OWASP AppSec France 2025 - Paris (France) 25-26 septembre 2025 : Paris Web 2025 - Paris (France) 2 octobre 2025 : Nantes Craft - Nantes (France) 2-3 octobre 2025 : Volcamp - Clermont-Ferrand (France) 3 octobre 2025 : DevFest Perros-Guirec 2025 - Perros-Guirec (France) 6-7 octobre 2025 : Swift Connection 2025 - Paris (France) 6-10 octobre 2025 : Devoxx Belgium - Antwerp (Belgium) 7 octobre 2025 : BSides Mulhouse - Mulhouse (France) 9 octobre 2025 : DevCon #25 : informatique quantique - Paris (France) 9-10 octobre 2025 : Forum PHP 2025 - Marne-la-Vallée (France) 9-10 octobre 2025 : EuroRust 2025 - Paris (France) 16 octobre 2025 : PlatformCon25 Live Day Paris - Paris (France) 16 octobre 2025 : Power 365 - 2025 - Lille (France) 16-17 octobre 2025 : DevFest Nantes - Nantes (France) 17 octobre 2025 : Sylius Con 2025 - Lyon (France) 17 octobre 2025 : ScalaIO 2025 - Paris (France) 20 octobre 2025 : Codeurs en Seine - Rouen (France) 23 octobre 2025 : Cloud Nord - Lille (France) 30-31 octobre 2025 : Agile Tour Bordeaux 2025 - Bordeaux (France) 30-31 octobre 2025 : Agile Tour Nantais 2025 - Nantes (France) 30 octobre 2025-2 novembre 2025 : PyConFR 2025 - Lyon (France) 4-7 novembre 2025 : NewCrafts 2025 - Paris (France) 5-6 novembre 2025 : Tech Show Paris - Paris (France) 6 novembre 2025 : dotAI 2025 - Paris (France) 6 novembre 2025 : Agile Tour Aix-Marseille 2025 - Gardanne (France) 7 novembre 2025 : BDX I/O - Bordeaux (France) 12-14 novembre 2025 : Devoxx Morocco - Marrakech (Morocco) 13 novembre 2025 : DevFest Toulouse - Toulouse (France) 15-16 novembre 2025 : Capitole du Libre - Toulouse (France) 19 novembre 2025 : SREday Paris 2025 Q4 - Paris (France) 20 novembre 2025 : OVHcloud Summit - Paris (France) 21 novembre 2025 : DevFest Paris 2025 - Paris (France) 27 novembre 2025 : DevFest Strasbourg 2025 - Strasbourg (France) 28 novembre 2025 : DevFest Lyon - Lyon (France) 1-2 décembre 2025 : Tech Rocks Summit 2025 - Paris (France) 5 décembre 2025 : DevFest Dijon 2025 - Dijon (France) 9-11 décembre 2025 : APIdays Paris - Paris (France) 9-11 décembre 2025 : Green IO Paris - Paris (France) 10-11 décembre 2025 : Devops REX - Paris (France) 10-11 décembre 2025 : Open Source Experience - Paris (France) 28-31 janvier 2026 : SnowCamp 2026 - Grenoble (France) 2-6 février 2026 : Web Days Convention - Aix-en-Provence (France) 3 février 2026 : Cloud Native Days France 2026 - Paris (France) 12-13 février 2026 : Touraine Tech #26 - Tours (France) 22-24 avril 2026 : Devoxx France 2026 - Paris (France) 23-25 avril 2026 : Devoxx Greece - Athens (Greece) 17 juin 2026 : Devoxx Poland - Krakow (Poland) Nous contacter Pour réagir à cet épisode, venez discuter sur le groupe Google https://groups.google.com/group/lescastcodeurs Contactez-nous via X/twitter https://twitter.com/lescastcodeurs ou Bluesky https://bsky.app/profile/lescastcodeurs.com Faire un crowdcast ou une crowdquestion Soutenez Les Cast Codeurs sur Patreon https://www.patreon.com/LesCastCodeurs Tous les épisodes et toutes les infos sur https://lescastcodeurs.com/

With the dust settled, we can finally see just how much Integrated Systems Europe has grown with their recent 2025 outing in Barcelona. Do these numbers mean good things for our industry? Talking about HDR (High Dynamic Range) and other options within displays that integrators should be talking to their clients about. And after our previous discussion about (blank) Blu-rays going the way of the dodo, we discuss what that means for physical media.Every week we look at the residential side of the AV industry and find the stories that integrators need to know about. We discuss these topics with a panel of experts in our channel. Joining us this week is Jeremy Glowacki from Projector Central and Rob Jones of Mangetar.Host: Matt ScottGuests:Jeremy Glowacki – Projector CentralRob Jones – MagnetarLinks to sources:HiddenWires – ISE 2025 Final NumbersCE Pro – HDR10+ White paperPC World – Blu-ray discs and Physical MediaSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

In this episode, host Matt Payne sits down with photographer and tech expert Greg Benz to delve into the world of HDR (High Dynamic Range) technology. They discuss the benefits of HDR displays, especially Apple's Pro Display XDR and Asus monitors, for photographers looking to enhance their editing experience. Benz highlights the advantages of HDR for capturing detailed images, outlines the process for accurately calibrating monitors, and suggests experimenting with HDR on newer devices. The conversation covers the efficiency of the AVIF format for image sharing, the functionality of Greg's Lumenzia Photoshop panel for luminosity masking, and practical tips for merging exposures in Lightroom to reduce noise. Benz also touches on the differences between editing for HDR displays and printing, suggesting tools and methods to achieve optimal results in both mediums.

Streaming has become the dominant format for both music listening and video viewing. Music streaming services account for 84% of all music listening and 89% of music industry revenue. Video streaming services account for approximately 95% of the home video market. Fully 99% of US households subscribe to one or more video streaming services as of 2023. Many video streaming services can deliver video in high quality 4K resolution with HDR (High Dynamic Range) for a gorgeous image. But those who seek out and appreciate the finest possible sound quality may find actually getting that high quality sound through a streaming service is more complicated than it should be. In this episode, eCoustics founder and CEO Brian Mitchell and Editor-at-Large Chris Boylan discuss the options out there for high quality audio including immersive sound, aka “spatial audio,” lossless music and even high resolution audio. Which services do it right? Which do it wrong? Listen in to find out. Thank you to our sponsors SVS & QAcoustics!

On today's show we run through some of the new features on the recently announced AppleTV, look at the tradeoff of using an indoor TV outdoors in a protected environment, and we have a short review of the Wyze V3 outdoor camera. We also read your emails and take a look at the week's news. New AppleTV From the Press Release - Apple announced the next generation of Apple TV 4K, delivering high frame rate HDR with Dolby Vision and connecting customers to their favorite content with the highest quality. At the heart of the new Apple TV 4K is the A12 Bionic chip that provides a significant boost in graphics performance, video decoding, and audio processing. And with an all-new design, the Siri Remote makes it even easier to watch shows and movies on Apple TV with intuitive navigation controls. Together with tvOS — the most powerful TV operating system — Apple TV 4K works seamlessly with Apple devices and services to magically transform the living room in ways that everyone in the family will love. Improved Video Experiences With A12 Bionic, Apple TV 4K now supports high frame rate HDR (High Dynamic Range) and Dolby Vision video, enabling fast-moving action at 60 frames per second (fps) to play more smoothly and appear more lifelike than ever before. Apple is working with leading video providers around the world, including FOX Sports, NBCUniversal, Paramount+, Red Bull TV, and Canal+, as they begin to stream in high frame rate HDR. And with high frame rate support in AirPlay, videos shot on iPhone 12 Pro can be displayed in full 60-fps Dolby Vision on the new Apple TV 4K.  Color Balance Through an innovative color balance process, Apple TV works with iPhone and its advanced sensors to improve a television's picture quality. Apple TV uses the light sensor in iPhone to compare the color balance to the industry-standard specifications used by cinematographers worldwide. Using this data, Apple TV automatically tailors its video output to deliver much more accurate colors and improved contrast — without customers ever having to adjust their television settings. Siri Remote The all-new Siri Remote features an innovative clickpad control that offers five-way navigation for better accuracy, and is also touch-enabled for the fast directional swipes Apple TV users love. The outer ring of the clickpad supports an intuitive circular gesture that turns it into a jog control — perfect for finding a scene in a movie or show. And with its one-piece aluminum design, the new Siri Remote fits more comfortably in a user's hand. The new Siri Remote also has a power button that controls a TV's power, and another for mute, making it the only remote needed while enjoying TV. Using Siri, customers can easily search for specific shows or movies, control smart home accessories, check sports scores or the weather, and much more. Siri now works on Apple TV in Austria, Ireland, and New Zealand, joining the 13 countries and regions that already support Siri.

Furrion Unveils Newest Line Of Outdoor 4K TVs On a recent show a listener asked us about installing a TV on his deck. The deck was protected from direct contact with the elements. We suggested using a regular indoor TV stating that it would shorten the lifespan of the TV but the cost saving would allow for a new TV every few years which would bring upgrades along the way.  Today we can quantify the cost comparison as Furrion unveiled a new line of outdoor TVs. The Aurora® Partial Sun 4K UHD LED Outdoor TV and the Aurora® Full Shade 4K UHD LED Outdoor TV. For our listener, since his TV would be on his covered deck, our comparison will be with the Full Shade 4K UHD. But for completeness we'll include the pricing for the Partial Sun TV as well.  From Furrion's Press Release: Furrion Aurora TVs are weatherproof in all conditions, and are engineered to withstand the harsh effects of UV rays, rain, snow, dirt, insects, and humidity. Their weatherproof housing and IP54 rating mean the Aurora is built to last, and the weather-resistant media bay offers even more protection for inputs and outputs. Even the remote control features an IP64 waterproof rating, great for areas with pools. Aurora® Partial Sun 4K UHD LED Outdoor TV Designed for partially shaded outdoor living areas like patios, decks and yards Increased brightness up to 750 nits and an anti-glare LCD screen give you an excellent picture in partially sunny areas Sizes: Available in 43”, 49”, 55” and 65” Pricing: $1,499.99 (43”), $1,999.99 (49”), $2,699.99 (55”), $3,399.99 (65”) Aurora® Full Shade 4K UHD LED Outdoor TV Designed for fully-shaded outdoor living areas like covered patios or screened gazebos Increased brightness up to 400 nits and an anti-glare LCD screen give you an excellent picture in partially shaded areas Sizes: Available in 43”, 49”, 55” and 65” Pricing: $1,299.99 (43”), $1,599 (49”), $1,999.99 (55”), $2,799.99 (65”) Analysis Let's go with a 50” TV. Costco has models starting at $340 (Hisense 50" R6 Series - UHD LED) or a Vizio for $430 (Vizio 50" M-Series - 4K Quantum LED). There are TCLs that are in the middle so for this exercise we'll say you can pick up a 50 inch TV for $400. That means for the price of a 50 inch Full Shade Aurora you can buy four regular TVs. Depending on your local climate that can really save you money. Of course this only works for a protected installation that is not in direct weather.  Wyze Cam v3 After receiving Chuck's email we decided to spend the whopping $31.84 including shipping and tax to test out the Wyze Cam v3. This is a very quick review. Essentially the camera is fantastic. In a side by side comparison with our Eufy cameras the Wyze had a sharper and more detailed picture with a spectacular night vision feature.  Wyze offers cloud storage for free but only a 12 second clip that rolls over every 14 days. You can upgrade to a plan that has longer recordings and more storage for about $25 a year. If you don't want to store in the cloud the camera supports a micro SD card with recordings available over the internet. The camera is IP65 weather resistant. Quite frankly the camera is amazing for only $30 shipped! Setup was simple. Like pretty much all the other cameras you download the app and add the camera. The app is easy to navigate and functional. All the controls and settings are easily accessed. The only complaint Ara had was that the camera is not supported by Homekit. Actually, the only platform that it supports is Alexa.  Bottom line, the days of expensive cameras are done. If you are a manufacturer trying to sell a camera for more than $50, be prepared to drop your prices. If Wyze ever supports Homekit, all Ara's outdoor cameras will be replaced at a total cost of $120!   

Receiver Buying Guide 2020 It's that time of year where we get to spend your money. This season we start off with AV Receivers. We take a practical approach with these guides in that we try to get you the best bang for your buck. Well we do indulge with one of our selections. Here is our AV receiver buying guide for 2020. Under $500 Sony STR-DN1080 7.2ch Home Theater AV Receiver (MSRP $499.99) The Sony STR-DN1080 is a receiver that has been out for a few years but still checks all the boxes for a 4K receiver that won't break the bank. If you spent a few hundred dollars on a new 4K TV at a Black Friday sale or will do so between now or Christmas this is the perfect receiver for you. We are not going to recommend that you spend a thousand dollars on a receiver for a $300 TV.  Even still, this receiver is packed with a lot of features.  Features: 6-in/2-out HDMI connectivity with 4K/60p (4:4:4)7 pass-through, HDCP 2.2 support, and HDR support Dolby Atmos® and DTS:X support High-Resolution Audio-compatible Wi-Fi®, AirPlay and Chromecast built-in for music streaming One-cable HDMI eARC With Google Home $500 to $750 Onkyo TX-NR797 9.2 - Channel Network A/V Receiver (Street Price $750, Back Ordered) The Onkyo TX-NR797 makes our list as a solid mid-level receiver with high end features typically found in receivers costing more than $1000.

Do we think you will need 8K support anytime in the near future? Probably not. But this receiver can handle it if you do. Of course it supports all the audio formats, HDMI eARC, HDCP 2.3, and so much more. This receiver does it all and at $850 it's hard to beat!

We are so impressed with Denon's 2020 lineup that we decided to stick with them for this category. Our top selection this year is the Denon AVR-X6700H. There are more expensive receivers out there but not necessarily better. The 6700 has everything we like about the 2700 but more!   Features: Premium 140W per channel (8 ohms, 20Hz-20kHz, THD: 0.08%, 2 ch. driven) amplifier designed specifically for demanding speakers  8K/60Hz pass-through, 4K/120Hz* pass-through for gaming, and support for the latest HDMI specifications Dolby Atmos, Dolby Atmos Height Virtualization Technology, DTS:X, DTS Virtual:X and IMAX Enhanced Support for DTS:X Pro via a future firmware update Can process 13.2 channels with an additional amplifier  HDMI section (7 in/3 out) with a dedicated 8K input that will support 8K/6OHz and 4K/120Hz video pass-through and upscaling HDR10, HDR10+, Dolby Vision, Hybrid Log-Gamma (HLG), Dynamic HDR, 3D, and BT.2020 pass-through support 4K/120Hz* pass-through and upscaling, as well as Variable Refresh Rate (VRR), Quick Frame Transport (QFT), and Auto Low Latency Mode (ALLM), which reduces or eliminates lag and frame tearing to offer a smoother, lag-free gaming experience.

Televizoarele au evoluat fantastic de mult în ultimii ani. E adevărat, la fel ca multe alte aparate din casele noastre. Televizorul, însă, a fost mereu, dincolo de un mijloc de informare, un aparat destinat distractiei, împreună cu familia sau cu prietenii, și o modalitate foarte bună de deconectare la finalul unei zile de muncă sau a unei săptămâni grele. Televizoare 3D si ... plasme Dacă întrebam pe oricine în urmă cu cinci ani ce tehnologie așteaptă să încerce pe un televizor, răspunsul ar fi fost în 9 din 10 cazuri termenul „3D”. Acum, la cinci ani distanță, 3D-ul este deja istorie, un experiment eșuat, doar un episod din viața lungă și alambicată a televizoarelor. La fel și ”plasma”. Două inovații, două încercări ale industriei televizoarelor, care au dat greș. Asta nu înseamnă, însă, că producătorii se opresc din continua misiune de a moderniza și upgrada televizoarele. Noi și noi tehnologii apar pe piață de la an la an, chiar, într-un ritm amețitor, care face ca un televizor de acum trei ani să fie acum obsolet. În special la CES (Consumer's Electronic Show) de la Las Vegas, producătorii se întrec în noi lansări de televizoare, cu noi tehnologii, cu noi funcții și cu noi inovații. Televizoare si tehnologii Pintre aceste noi tehnologii se numără și HDR (High Dynamic Range). Acesta poate fi considerat un profil de imagine care poate afișa mai multe culori și mai multe grade de luminozitate, oferind o filmelor și jocurilor capacitatea de a fișa cadre mult mai apropiate de realitate. HDR-ul a explodat în popularitate în ultimul an, fiind deja promovat în aplicațiile de streaming, dar și în jocurile specifice consolelor PlayStation și Xbox. Următorul pas este ca televiziunile să emită în formatul promovat de către producători. La fel ca trecerea de la SD la HD, trecerea la HDR ar trebui să fie următorul capitol al evoluției televiziunii. Încercarea de a obține imagini cât mai fidele realității ține foarte mult de costurile de producție raportate la costurile de vânzare. Astfel, pe piață găsim televizoare ce implementează diferite tehnologii de afișare a imaginilor. Cum aminteam mai sus, ecranele de tip “plasma” au dispărut de mult timp, deși numele dăinuie și astăzi, însemnând în cultura populară autohtonă “televizor cu ecran plat”. În funcție de preț, întâlnim în continuare televizoare cu tehnologii LCD IPS (cu unghiuri largi de vizualizare, dar fără un contrast spectaculos) și OLED (unghiuri largi de vizualizare, contrast foarte bun, saturație excelentă a culorilor, însă cu o luminozitate ce poate dezamăgi anumiți consumatori). TV online - QLED Noi tehnologii precum QLED (quantum dot LED), dezvoltate de Samsung, vin să rezolve problemele celor mai pretențioși consumatori de multimedia și gaming. Din păcate însă, tehnologia se află la început, motiv pentru care prețurile sunt în continuare mari. Vestea bună este că astfel de tehnologii evoluează foarte rapid și ne putem aștepta la o coborâre rapidă a prețurilor în decurs de un an sau doi. Și cine știe ce alte inovații ne mai așteaptă din această lume minunată a televizoarelor. Piaţa locală de televizoare creşte în fiecare an şi nu este de mirare având în vedere apetitul românilor pentru „micul ecran“. Media timpului petrecut de români în faţa televizorului este aproape dublă faţă de media globală. Televizoarele vor continua să se bucure de succes mult și bine în țara noastră. #tv

I first became aware of Burning Man through the gorgeous imagery of travel photographer Trey Ratcliff.  He is known for his use of HDR (High Dynamic Range) in his photographs. On today's episode, we talk about photography, Burning Man, and psychedelics.   

There's a new format war going on and it's revolving around HDR (High Dynamic Range).

Este viernes hemos llegado al podcast de Escuela de Video con dos temas El 4K y HDR. El primero de ellos, conocido en algunas de sus facetas pero no tanto en otras y el HDR (High Dynamic Range, o Alto Rango Dinámico ) un tema menos conocido y menos hablado. Y eso que seguro que lo hemos oído todo el mundo alguna vez. Como siempre charlamos de nuestra vida y preocupaciones y ocupaciones, no adelantamos más, ¡mejor es escucharlo! Volviendo al tema principal, estos son los puntos que tratamos. - Explicamos qué es el HDR y las diferentes aplicaciones qué tiene en el vídeo. - Analizamos el presente y futuro del alto rango dinámico y como se pueden conseguir grabaciones con las cámaras de vídeo. Y por supuesto lo desvinculamos del HDR de la fotografía. - Diferenciamos el 4K del HDR, ¡no es lo mismo!. Grabar en 4 K no significa tener la mejor imagen. Esto depende de muchos otros factores, por ejemplo el códec. - Hablamos del perfil de color bt 2020. ¿Por qué no llega al mercado audiovisual de una vez? - Y finalmente damos algunos tips sobre qué tenemos que tener en cuenta a la hora de grabar vídeo en HDR y cuál sería la configuración de cámara adecuada. Al igual Fran nos cuenta que con el subescalado del formato de imagen ganamos calidad en el vídeo. Recuerda que si tienes dudas, sugerencias, propuestas nos puedes contactar a través de [nuestro formulario de contacto](https://www.escueladevideo.com/contactar), y que puedes escucharnos en [iVoox](www.ivoox.com/podcast-escuela-video_sq_f1504724_1.html), [iTunes](https://itunes.apple.com/es/podcast/escuela-de-video/id1349746105?mt=2) y [YouTube.](https://www.youtube.com/channel/UCqJGdFrquI8pM8AJM26dKIw) ©2018 Escuela de Video www.escueladevideo.com

Volvimos!! Despues de unas mini vacaciones del podcast volvimos con muchas cosas nuevas, la produccion de The Batman y Avengers: Infinite War, ademas, las nuevas series de Netflix, Santa Clarita Diet y Riverdale y las series semanales de CW. Ademas, les explicamos de que se trata la tecnologia 4K y que significa la categoria HDR (High Dynamic Range) y muchas cosas mas!!! Bienvenidos a Cabeza de Nerd!!!

What is HDR? For more than a year now we have been talking about 4K TVs and how they are supposed to be the next big thing. But in actuality the increased resolution is only mildly better than equally spec'd 1080p HDTVs. We have pointed to case study after case study that says you need very large (100” or more) screen to see a difference between 1080p and 4K when sitting at normal viewing distances. This alone is not a good reason to upgrade. What has us really excited is what is coming along with these new UHDTVs, HDR (High Dynamic Range) and that IS a good reason to go out and buy a new UHDTV. We have mentioned HDR on previous shows but we we never really talked about what HDR entails in any detail. We thought it would be a good idea to explain what HDR is and why you will want this on your next TV. First we need to differentiate between HDR in photos and HDR in TVs. Photo HDR combines multiple images with different exposures to create a single image that mimics a greater dynamic range. TV HDR expands the TV's contrast ratio and color palette to offer a more realistic, natural image than what's possible with today's HDTVs. Photo HDR can make a picture look unrealistic whereas TV HDR actually makes the picture look more realistic. HDR capable TVs coupled with HDR content will display a more realistic color range, higher contrast ratio which in turn yields deeper blacks and brighter more vivid colors. HDR is far more important to your next TV purchase than 4K but at this point in time it is unlikely that there will be a 1080p HDTV that supports HDR so you will end up with a 4K TV regardless. A TV's ability to display a wider and richer range of colors, brighter whites, and deeper, darker blacks gives the TV picture a more ‘dynamic' look, which is where the name comes from. Format War There are two HDR formats vying for your dollars, one from Dolby and one from Technicolor. However this format war is not like Blu-ray vs HDDVD. You will unlikely be stuck with an orphaned UHDTV. Both of these formats support the HDR-10 specification which is supported by UHD players. Streaming services will more than likely support the HDR-10 format although Netflix has some support for Dolby Vision on some of their original content.   Some TVs manufacturers are supporting both so it's unlikely that you will be stuck with a TV that won't support HDR content. If we had to choose between a TV that supported only one format we would pick the one that supports Dolby Vision. Dolby has always been out front with it's support at the point of content creation. They are at the studios working with sound mixers and video professionals to make sure their format looks and sounds best. We heard this with Dolby TrueHD and we expect the same with Dolby Vision. How Do I Know Which TV to Buy? At CES, the UHD Alliance, a 35-member consortium released a standard called “Ultra HD Premium” which is supposed to make it easy for consumers to identify UHDTVs that meet their specification. To be certified Ultra HD Premium a UHDTV must achieve a brightness of at least 1000 nits. There is no specific HDR specification but there are for black levels and color gamut which will guarantee a minimum level if HDR quality. What about cables? You won't need new cables for HDR. Current High-Speed HDMI cables can carry HDR content. The source device (a 4K Blu-Ray player, say) and TV must be HDMI 2.0a to transmit the metadata, however. If you have a receiver and want to use it for switching, it will need to be HDMI 2.0a as well. HDR content (the key) All these new features won't really do anything to enhance your experience unless you have content that takes advantage of it. HDR content is starting to trickle out now and more is on the way. Amazon has a few titles in HDR (Mozart in the Jungle, Red Oaks, and a few others) and Vudu is offering HDR content in Dolby Vision. Netflix streams Marco Polo and Daredevil in HDR. There are also UHD discs that support HDR so if you have a UHD TV that supports HDR you should be able to find something to watch and show it off! To Sum it Up Getting the best picture from an HDR TV will require HDR content. To guarantee your TV will support HDR look for the “Ultra HD Premium” label. If you really want a UHD TV that does not have the “Ultra HD Premium” label buy a TV that has or comes close to 1000 nits brightness. HDR from cable, satellite, and OTA are still a bit off.

CEDIA 2015 Each year CEDIA (Custom Electronic Design and Installation Association) holds an event where the industry gathers to show off their wares. Kinda like a mini-CES, but also like a best of CES, we've been to a few of these and actually enjoy the show more than CES. It takes the parts of CES that we are interested in and compresses it down to a more manageable show. We didn't go this year but that won't stop us from talking about some of the products we think are interesting. This year the show was from October 14-17 in Dallas, TX. Sony Electronics Announces 4K Home Theater Projectors at CEDIA 2015 Sony Electronics is expanding its home theater line-up by announcing new projectors at CEDIA 2015. The new projectors include the VPL-VW665ES and VPL-VW365ES, which deliver native 4K resolution and a new long-lasting lamp gives both up to 6,000 hours of performance, with high brightness and high contrast for even more vibrant images.   The VPL-VW665ES is compatible with HDMI input of HDR (High Dynamic Range) content with a 300,000:1 dynamic contrast ratio. Sony is developing HDR support across its portfolio and the VPL-VW665ES gives home cinema enthusiasts the opportunity to experience total immersion in whatever they are watching. The new VPL-VW665ES and VPL-VW365ES use advanced SXRD™ panels for a native 4K picture, with no artificial manipulation of pixels.   Both new models allow users to enjoy up-to-date 4K content services through the latest connectivity options using the latest HDMI standard and HDCP 2.2. The new projectors will be available in October 2015 at a suggested retail price of $3,999 for the VPL-HW65ES, $9,999 for the VPL-VW365ES and $14,999 for the VPL-VW665ES. SunBriteTV Unveils 84-, 55-Inch Outdoor 4K TVs SunBriteTV has announced its entry into 4K UHD with two new outdoor televisions, including an 84-inch Pro Series model (SB-8418UHD), its largest screen size to date, and a 55-inch Signature Series unit (SB-5574UHD). Designed for permanent outdoor installation, both the SB-8418UHD and the SB-5574UHD feature weatherproofing technology that protects internal components from rain, snow, dust, salt corrosion, insects, and humidity. Specialized high-brightness anti-glare screens differ from those of indoor televisions for a 3840 x 2160p 4K UHD viewing experience. Both units come with a 20W detachable weatherproof speaker bar.   Shipping dates and pricing for both units will be released later this year. The SB-8418UHD, part of SunBriteTV's Pro Series, also features a glass shield to provide extra protection for the LED panel.

A new iOS and Android mobile interface to manage smart locks, for family members to easily lock or unlock a door, add or delete users, and grant temporary home access. All security zones are now available in a single interface and simplifies the management of all the security zones in the smart home, including the ability to close a gate or a garage door with a single tap. A new searchable event-history agent that records security incidents throughout the home to provide a sequenced and contextual understanding of activity, which in turn can be used to inform homeowners via mobile alerts and push-notifications that are timely and relevant.   Control4 has also announced new “experience” drivers that help simplify programming for highly-personal experiences inside of a Control4 Smart Home. The all-new MockupancyTM capability remembers the every-day routines and actions of the household within the home, allowing a Control4 homeowner to play back those routines and actions while they are away – simulating the organic feel of an occupied residence. Specifically, Mockupancy can coordinate lighting, shades, and even TV entertainment and music streaming to mimic normal household occupancy. The all-new Snapshot driver simplifies the capture of the current state of connected devices throughout the home, including lighting, entertainment and comfort control. A dealer can then program the system to recall the scene with a single tap or button press. The driver database has expanded to integrate over 9,500 compatible devices; Control4 has released free drivers for over 700 devices since the acquisition of Extra Vegetables in September of 2014, including popular smart devices from Amazon, Sony, Samsung, TiVo, Hunter Douglass, Bang & Olufsen, and Bowers & Wilkins among many others.

LP Smart Products Collaborates With Elite Home Theater Seating To Design Smart Seating Of The Future Leggett & Platt Smart Products announced a collaboration with Elite Home Theater Seating Inc. at CEDIA EXPO to create technology-enabled, high-end theater chairs that can detect human occupancy. The seating combines LP Smart Products' LPSense® and LPConnect® technology in its launch of LPConnect Package with Elite's luxury handmade theater seating. The LPConnect Package can be implemented into any piece of home furniture and includes several customizable features including auto stop safety control, easy integration with existing automation systems, memory presets, and control over Wi-Fi, Bluetooth low energy, and Zigbee.   When implemented into Elite's theater chairs, individual preferences can be stored into memory presets using LPSense and LPConnect. Its LPSense technology uses capacitive sensing to detect human presence and trigger actions based on activity, such as playing or pausing a movie when the user gets in or out of the theater chair. The chair and other connected furniture can also be programmed to adjust room settings with its LPConnect technology. Fibaro gesture control and first Wi-Fi-enabled doorbell/intercom/security camera To enable gesture control of devices connected to Fibaro's Home Center 2 Z-Wave hub, the company developed a battery-operated panel that can be placed behind picture frames, behind walls or under countertops to sense the capacitance of a moving hand. The panel recognizes six gestures: up, down, left, right, circle left, and circle right. It also recognizes combinations of gestures. Consumers would program in the devices or scenes that a gesture would control. The panel, called the Swipe, will be available the end of November at a targeted $149.   The company's first intercom/doorbell with integrated camera features Wi-Fi, Bluetooth, and Power over Ethernet. The device, called the Fibaro Intercom, gets power from an existing doorbell system. It uses motion and sound sensing to launch 4K video recording, sends doorbell video over Wi-Fi for in-house or remote viewing on a mobile device, and incorporates Bluetooth. With Bluetooth, the Intercom senses when an authorized user's phone is within a set range, then automatically sends a 12-volt signal to unlock a connected electronic lock. Also to unlock a connected electronic lock, users rotate the device's bezel to enter a numeric security code. It will be available in December at around $500.

Sonos Over in the whole-house audio category, wireless category leader Sonos is not resting on its past accomplishments. A few weeks ago the company introduced its new Play:5 active loudspeaker that incorporates new drivers, amplification, crossover networks and a new industrial design. Headlining its software tweaks, the company has added its TruePlay auto room equalization technology.   Demonstrating the technology, Sonos asks dealers to watch a quick video that shows how simple the EQ is. Taking approximately 55 seconds, TruePlay uses the microphone in users' iOS devices to measure room interactions. Once completed, TruePlay cleans up common sound issues such as muddy bass and smeared top end. Summing up the technology, Sonos states it underscores its pursuit of “pure musical truth.” The tenets of its musical truth include full-frequency clarity, stereo imaging and well defined bass performance.
