Single-stream transmission method for multi-user video conferencing

摘要

A method includes transmitting, from an encoding client to a first remote computing system, an encoded video stream that includes a plurality of first-resolution frames and a plurality of second-resolution frames. The method also includes transmitting, from the encoding client to the first remote computing system in the encoded video stream, a first-resolution non-displayed anchor frame. The method also includes receiving, at the encoding client from the first remote computing system, a request to change resolution. In response to receiving the request to change resolution, the method includes transmitting, from the encoding client to the first remote computing system in the encoded video stream, a set of frames that are encoded relative to the first-resolution non-displayed anchor frame.

1. A method, comprising:
encoding, by an encoding client, a plurality of first-resolution frames and a plurality of second-resolution frames, wherein each of the first-resolution frames and each of the second-resolution frames is encoded with reference to a respective same resolution frame from a previous time period; transmitting, from the encoding client to a first remote computing system, an encoded video stream that includes the plurality of first-resolution frames and the plurality of second-resolution frames; transmitting, from the encoding client to the first remote computing system in the encoded video stream, a first-resolution non-displayed anchor frame, wherein the first-resolution non-displayed anchor frame is transmitted periodically during transmission of the encoded video stream; receiving, at the encoding client from the first remote computing system, a request to change resolution; in response to receiving the request to change resolution, performing a coding change in which the encoding client encodes a set of frames that are encoded with reference to the non-displayed anchor frame; and transmitting, from the encoding client to the first remote computing system in the encoded video stream, the set of frames that are encoded relative to the first-resolution non-displayed anchor frame.
