摘要： There is provided an information processing apparatus and an information processing method that enable uplink streaming to be performed adaptively. In an information processing system, a communication module that performs protocol negotiation for content uplink stream transmits to a different communication device a Service object that includes information regarding stream of a content for use in the protocol negotiation, receives from the different communication device information for negotiation transmitted on the basis of the Service object, and performs control protocol negotiation for the content uplink stream with the different communication device. The present technology can be applied to a communication system that performs uplink streaming, for example.

摘要： The development of a region of interest (ROI) video frame that includes only ROIs of interest and not other elements and providing the ROI video frames in a single video stream simplifies the development of gallery view continuous presence displays. ROI position and size information metadata can be provided or subpicture concepts of the particular codec can be used to separate the ROIs in the ROI video frame. Metadata can provide perspective/distortion correction values, speaker status and any other information desired about the participant or other ROI, such as name. Only a single encoder and a single decoder is needed, simplifying both transmitting and receiving endpoints. Only a single video stream is needed, reducing bandwidth requirements. As each participant can be individually isolated, the participants can be provided in similar sizes and laid out as desired in a continuous presence display that is pleasing to view.

摘要： A web server provides media content for playback on client devices that is associated with a set of enhanced features. When enabled, each enhanced feature provides functionality associated with and supplemental to the media content. The web server performs a handshake with each of a plurality of client devices to authenticate a communication channel. The web server enables one or more of the enhanced features while delivering media content for playback on a first device if information exchanged in the handshake with the first device satisfies a first criterion. The web server delivers the media content for playback on a second device, without enabling any of the enhanced features, if information exchanged in the handshake with the second device does not satisfy the first criterion.

摘要： It is possible to enable a reception side to easily recognize that metadata is inserted into an audio stream. A metafile including meta information for acquiring an audio stream into which metadata is inserted through a reception device is transmitted. The identification information indicating that the metadata is inserted into the audio stream is inserted into the metafile. At the reception side, it is possible to easily recognize that the metadata is inserted into the audio stream based on the identification information inserted into the metafile.

摘要： A virtual desktop server include an application framework comprising a real-time media application to provide real-time communications (RTC), a native RTC engine to execute a portion of the real-time media application when received, and a processor coupled to the application framework and to the native RTC engine. The processor redirects original application program interfaces (APIs) of the real-time media application intended for the native RTC engine based on redirection code injected into the real-time media application so that the portion of the real-time media application is to be redirected. The processor receives from a client computing device capabilities of the client computing device to execute the redirected portion of the real-time media application. The processor switches to a fallback mode if the client computing device has limited capabilities.

摘要： In some implementations, a computing system can reduce startup delays for presenting remote media items. For example, when a user requests media content from a media service, the computing system can include information about the first media item to be played in the initial startup messages to reduce the number of roundtrips needed between client and server devices to present the first media item. A media item can include an introductory asset. The introductory asset can be a portion of the full media item that can be decrypted with a local key or not encrypted at all so that a media client can receive and start presenting the introductory media asset quickly while the full media item is being processed by the media client. In some implementations, the system can remove leading silence from the media item so that the amount of delay perceived by the user is reduced.
