Abstract: A server includes a processor configured to determine, based on reception of information from a client device, synchronization parameters between a server clock rate associated with the server and a client clock rate associated with the client device. The processor is also configured to determine a client-side generation timestamp for an audio frame based on the synchronization parameters and based on a server-side generation timestamp for the audio frame. The processor is further configured to generate the audio frame. The audio frame includes the client-side timestamp.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for a mesh GPU codec for real-time streaming. A graphics processor may obtain an indication of a compressed representation of a topology associated with at least one generalized triangle strip associated with a subset of triangles in a set of triangles. The graphics processor may obtain an intermediate representation of the topology associated with the at least one generalized triangle strip by a decompression of the compressed representation. The graphics processor may obtain a sequence of indices based on the intermediate representation of the topology associated with the at least one generalized triangle strip. The graphics processor may compute at least one set of offsets based on the intermediate representation. The graphics processor may reconstruct the set of triangles based on the sequence of indices and the at least one set of offsets.

Abstract: The present disclosure relates to methods and apparatus for graphics processing. Aspects of the present disclosure can render at least one frame including display content at a server. Aspects of the present disclosure can also downscale the at least one frame including the display content, where a downscaling rate of one or more portions of the at least one frame is based on a location of each of the one or more portions. Moreover, aspects of the present disclosure can communicate the downscaled at least one frame including the display content to a client device. Aspects of the present disclosure can also encode the downscaled at least one frame including the display content. Further, aspects of the present disclosure can decode the encoded at least one frame including the display content. Aspects of the present disclosure can also upscale the at least one frame including the display content.
