Full reference video quality measurements of video conferencing over the congested networks
Various embodiments comprise systems, methods, and apparatus for processing a received video stream according to an embodiment comprises: identifying a number of repeated video frames within a sequence of N video frames within the video stream; determining, using a video frame quality assessment mechanism adapted to use repeated frames information, a motion adapted video quality metric (VQM) of the sequence of N video frames; and generating an alarm in response to the motion adapted VQM being less than a threshold level.

Media streaming
A method for streamed playback of media in a media client from a remote media service includes: a) determining address information for locating the service and for a starting time; b) by the address information, requesting and receiving a first media package from the service; the package having decoder configuration information, one or more frames, associated timing information for playback frames, and a pointer to a subsequent part of the media stream; c) configuring a decoder of the client by the decoder information; d) starting playback of the stream in the client at the starting time by providing the frames to the configured decoder; e) by the pointer, requesting a remaining portion of the media having subsequent frames of the media stream and associated timing information; f) receiving the subsequent frames as a stream and continuing playback by providing the subsequent frames and associated timing information to the configured decoder.

AUDIO MIXING FOR TELECONFERENCING
In a teleconferencing method, a first media stream and a second media stream of a teleconference are received, by processing circuitry of a first device, from a second device. The first media stream includes first audio and the second media stream includes second audio. Default weight information is received from the second device. The default weight information indicates a first audio weight for weighting the first audio and a second audio weight for weighting the second audio. The first audio weight for weighting the first audio and the second audio weight for weighting the second audio are determined based on the default weight information. Mixed audio is generated, by the processing circuitry of the first device, by combining a weighted first audio based on the first audio weight applied to the first audio and a weighted second audio based on the second audio weight applied to the second audio.

High-level syntax designs for point cloud coding
A method of point cloud coding (PCC) implemented by a video decoder. The method includes receiving an encoded bitstream including a group of frames header disposed outside a coded representation of a texture component or a geometry component and identifying a video codec used for coding the texture component or the geometry component, and decoding the encoded bitstream.
Automatic Discovery and Reporting of Streaming Content of Interest and Connection of User to Same
Embodiments are directed to computer systems and methods that stream selected media content to a client device. Selection of particular content to stream to a device of a given user is performed based on parameters specified in advance by the given user. Selection is made from received content that is parsed, indexed, and stored in real-time in such a way as to allow for real-time monitoring and searching of the content according to the user-specified parameters. The user is alerted as to the discovery of the selected content and enabled to connect to a stream presenting the selected content. The selected content is presented within the stream beginning from a playback time corresponding to a moment that triggered the discovery of the selected content, even if the moment has passed, thus providing the user with a comprehensive presentation of the selected content.

Apparatus and system for virtual camera configuration and selection
A system and method for virtual camera configuration and selection. For example, one embodiment of a system comprises: a decode subsystem comprising circuitry to concurrently decode a plurality of video streams captured by cameras at an event to generate decoded video streams from a perspective of corresponding virtual cameras (VCAMs); video evaluation logic to apply at least one video quality metric to determine a quality value for the decoded video streams or a subset thereof, and to rank the decoded video streams based, at least in part, on the quality values associated with the decoded video streams; preview logic to provide the decoded video streams or modified versions thereof to one or more computing devices accessible to one or more video production team members and to further provide the quality values and/or the rank generated by the video quality evaluation logic; stream selection hardware logic to select a subset of the plurality of decoded video streams based on input from the one or more video production team members; and transcoder hardware logic to transcode the subset of the plurality of decoded video streams for live transmission over a public or private network.
