Abstract
One disclosed example method includes receiving, by a video conference provider, video frames from a plurality of existing participants in a video conference; receiving, by the video conference provider, a request from a new user to join the video conference, and in response: generating, by the video conference provider, an instantaneous decoder refresh (IDR) frame; determining, by the video conference provider, one or more prior video frames previously acknowledged by each existing participant of the plurality of existing participants; generating, by the video conference provider, a benchmark frame for each of the plurality of existing participants based on at least one of the determined one or more prior video frames and the IDR frame; transmitting, by the video conference provider, the IDR frame to the new user; and transmitting, by the video conference provider, a message comprising the benchmark frame to each of the plurality of existing participants.
