Depuis l'original – une "tablette" Android de 5 pouces greffée sur un gamepad de style Xbox lancé en 2013, Nvidia Shield a toujours été étrange. Les itérations suivantes sont devenues un peu plus normales, mais l'appareil a toujours épousé ses racines geek, centrées sur le jeu, tout en se transformant lentement en un appareil de télévision polyvalent axé sur le streaming vidéo.

Après de nombreuses fuites, le Nvidia Shield TV 2019 est mis en vente aujourd'hui avec deux modèles différents: le Shield TV Pro (200 $) et le bizarre Shield TV (150 $), qui ont l'air familier, ne ressemblent en rien à un gros stogie. Les deux promettent une qualité de streaming améliorée par rapport à l'excellent téléviseur 2017 Nvidia Shield, grâce à la conversion ascendante de l'intelligence artificielle 4K et aux supports Dolby Vision et Dolby Atmos. Voici comment ils se superposent et la version 2017.

Oui, c'est le nouveau bouclier de 150 $.

Prendre deux et passer

Donc à propos de ce cigare. Le téléviseur Shield de base à 150 USD intègre la plupart des fonctionnalités du Pro à 200 USD dans un cylindre noir avec les ports (notamment HDMI, fente pour carte SD, alimentation et Ethernet) à l’une ou l’autre des extrémités. Il est conçu pour se cacher derrière votre téléviseur ou votre rack AV. L'amélioration de la mémoire RAM et du stockage du Pro ne sera pas un gros problème pour la plupart des utilisateurs, mais les plexifs Plex voudront peut-être gagner plus d'argent pour la fonction Plex Media Server – les deux Shields peuvent exécuter l'application cliente Plex mais seul le Pro peut agir en tant que serveur aussi.

Les deux incluent également la nouvelle télécommande élégante de Nvidia, qui pourrait être la mise à niveau la plus bienvenue. Il arbore plus de boutons, y compris une touche en haut, vous pouvez programmer pour une variété de fonctions, du lancement d'applications aux réglages de réglages. Toutes les touches s'allument lorsque vous prenez la baguette. Elle fonctionne avec des piles AAA. Elle permet de contrôler le volume et d'allumer des téléviseurs compatibles via HDMI-CEC et l'infrarouge.

Et, mieux encore, il existe un système de recherche à distance – à la Roku Ultra ou Caavo – permettant au cliqueur d'émettre un son sous les coussins du canapé. Il peut être activé à partir d'un bouton situé sur Shield lui-même, à partir de la nouvelle application Shield sur votre téléphone ou en demandant à un interlocuteur Alexa ou Google Home couplé de trouver la télécommande.

Amélioration de l'IA: Netflix, à la rencontre du réseau de neurones

Je n'ai pas encore eu l'occasion de revoir complètement le nouveau Bouclier, mais d'après ce que j'ai vu lors de la démo de Nvidia, l'intensification de l'intelligence artificielle pourrait valoir la peine pour les téléspectateurs aux yeux perçants. Il a été conçu pour améliorer les détails et la netteté des vidéos HD standard et les rendre plus proches de la 4K. Son fonctionnement est plutôt cool. Nvidia a formé un réseau de neurones avec du contenu télévisé et vidéo provenant de sources telles que Netflix et la vidéo Amazon Prime, en le montrant à la fois en vidéo 4K native et en vidéo convertie à l’échelle numérique à l’aide de méthodes traditionnelles. Le réseau utilise la différence entre les deux pour appliquer une prédiction de ce à quoi la vidéo 4K devrait ressembler.

Nvidia

Le réseau formé réside dans le processeur Tegra X1 + et peut convertir toute vidéo – du standard 480p au 1080p – au 4K. Une limite cependant: il ne peut pas convertir une vidéo à 60 images par seconde. Ce n'est pas un gros problème puisque la plupart des contenus télévisuels et cinématographiques sont en 24 images par seconde, mais cela signifie que la montée en gamme de l'IA ne fonctionne pas avec les jeux ou certaines vidéos YouTube.

Le nouveau bouclier a un mode démo (disponible pour les utilisateurs finaux) qui place côte à côte la vidéo standard et convertie vers le haut en AI sur l'écran, et il était facile de voir l'amélioration sur un téléviseur OLED de 65 pouces à une vingtaine de mètres. Les détails étaient plus précis dans un paysage urbain de Coco, par exemple, ainsi que sur le visage de Tom Cruise dans la bande-annonce de Top Gun: Maverick. Les utilisateurs peuvent choisir parmi trois niveaux de détail et utiliser la conversion ascendante standard, ainsi que désactiver complètement l’effet. Ce niveau de montée en gamme est une première pour les streamers, bien que les téléviseurs Samsung effectuent également la montée en gamme par l'AI, et que Apple TV 4K donne l'impression que tout est en HDR. Je suis impatient de tester la version de Nvidia.

Le bouclier de 150 USD (à droite) vise directement le Apple TV 4K à 180 USD pour la suprématie du streaming Dolby Vision 4K haut de gamme.

Les nouvelles applications de Shield pour Netflix, Amazon Prime Video, Disney Plus, Vudu et Movies Anywhere gèrent toutes Dolby Vision et Dolby Atmos. Cette couverture Dolby rivalise bien avec l'Apple TV 4K et bat celle des streamers 4K d'Amazon Fire TV. Le décodage Dolby Atmos intégré, par opposition à la transmission sur le bouclier 2017, permet à Atmos de Netflix. Il convient toutefois de noter que l'application Apple TV et Apple TV Plus / iTunes ne sont pas disponibles sur Shield.

Comme son prédécesseur, le bouclier utilise le système d'exploitation Android TV de Google, qui, outre Apple TV, offre une sélection d'applications similaire à celle des streamers Roku, Fire TV et Apple TV. La version la plus récente donne à l'app store un lifting pour faire apparaître plus de catégories d'applications. Comme toujours, Google Assistant est intégré à l'aide de la télécommande vocale.

Les prouesses de Shield en matière de jeu sont en grande partie inchangées – il exécute des jeux Android à partir de Google Play, la plate-forme de jeu en nuage GeForce Now de Nvidia et peut diffuser des jeux depuis un PC sur votre réseau domestique via la fonction GameStream de Nvidia – mais la nouvelle version ne comprend pas de contrôleur de jeu. . Vous pouvez acheter séparément les cartes de Nvidia au prix de 60 $, avec l'assistant Google à champ moyen ou simplement coupler Shield à des contrôleurs Xbox, PlayStation ou tiers.
