Title (EN) REVERSE CASTING FROM A FIRST SCREEN DEVICE TO A SECOND SCREEN DEVICE
(FR) COULAGE INVERSE D'UN PREMIER DISPOSITIF D'ÉCRAN À UN SECOND DISPOSITIF D'ÉCRAN
Abstract:
(EN) In aspects of reverse casting from a first screen device to a second screen device, a mobile device implemented as the second screen device can determine that it is proximate in location to the first screen device, such as a television device, based on both the mobile device and the television device being connected to a local network. The mobile device and the television device can be automatically associated to enable data being synchronized between the two devices based on determining that the devices are proximate in location. The television device displays video content prior to the two devices being associated. The mobile device can then receive contextual information that corresponds to the video content being displayed on the television device. The contextual information can be determined by an automated analysis of the video content at a video content service as the video content is distributed to the television device.
(FR) L'invention concerne, dans des aspects du coulage inverse d'un premier dispositif d'écran à un second dispositif d'écran, un dispositif mobile mis en œuvre en tant que second dispositif d'écran pouvant déterminer qu'il est à proximité d'un emplacement sur le premier dispositif d'écran, tel qu'un dispositif de télévision, sur la base à la fois du dispositif mobile et du dispositif de télévision connecté à un réseau local. Le dispositif mobile et le dispositif de télévision peuvent être automatiquement associés pour permettre la synchronisation de données entre les deux dispositifs sur la base de la détermination que les dispositifs sont à proximité de l'emplacement. Le dispositif de télévision affiche un contenu vidéo avant que les deux dispositifs ne soient associés. Le dispositif mobile peut ensuite recevoir des informations contextuelles qui correspondent au contenu vidéo affiché sur le dispositif de télévision. Les informations contextuelles peuvent être déterminées par une analyse automatisée du contenu vidéo au niveau d'un service de contenu vidéo lorsque le contenu vidéo est distribué au dispositif de télévision.
