摘要： An example apparatus may include a display device, a video splitter, and a video switch. The video splitter may receive a first video stream in a first direction and may split the first video stream into a first split video stream and a second split video stream. The video splitter may send the first split video stream to the display device and send the second split video stream in the first direction to be received at a downstream device. The video switch may receive a second video stream in a second direction that may be different than the first direction. The video switch may switch a path through the video switch based on a location of a video source for the second video stream.

摘要： Techniques are disclosed relating to encoding recorded content for distribution to other computing devices. In some embodiments, a first computing device creates recorded content for transmission to a second computing device configured to present the recorded content. To encode the recorded content, the first computing device detects, via a network interface of the first computing device, one or more computing nodes available to encode the recorded content in one or more formats supported by the second computing device. The first computing device offloads the recorded content via the network interface to the one or more computing nodes for encoding in the one or more formats. In some embodiments, the second computing device receives a request from a user to stream content recorded by a first computing device and requests the content in a first format being encoded by a computing node assisting the first computing device.

摘要： The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. An apparatus includes a communication interface and a processor operably coupled to the communication interface. The communication interface receives, from an application provider, a signaling message for provisioning into a network-based media processing (NBMP) workflow manager. The processor assumes a role of the NBMP workflow manager.

摘要： L'invention répond à ce besoin en proposant un procédé de gestion de zapping d'un premier à un second contenu numérique. Ces premier et second contenus numériques sont obtenus par téléchargement progressif adaptatif (HAS) par un terminal lecteur de flux multimédia, et sont respectivement associés à un fichier de description, comprenant une liste de segments temporels du contenu associés chacun à plusieurs débits d'encodage du contenu. Ce procédé de gestion de zapping comprend : - une réception d'une requête de zapping du premier contenu numérique vers le second contenu numérique, - une obtention du fichier de description dudit second contenu numérique. Selon l'invention, un tel procédé comprend également : - une sélection d'un débit d'encodage d'un premier segment temporel dudit second contenu numérique à télécharger, en fonction, d'une part d'une contrainte de ressource obtenue par ledit terminal lecteur de flux multimédia, et d'autre part d'un temps de zapping cible, - un téléchargement dudit premier segment temporel dudit second contenu numérique audit débit sélectionné.
