Abstract
A system and process for highlighting the current speaker on an on-going basis in each frame of a low frame-rate video of an event having multiple people in attendance, such as a video teleconference, is presented. In general, this is accomplished by periodically identifying an attendee that is currently speaking at a rate substantially faster than the video frame rate, and for each frame of the video updating the frame to highlight the attendee currently speaking. More particularly, an audio/visual (A/V) source provides separate video, audio, and current speaker data streams to a client computing device. The client device then uses these data streams to render and display the video and to periodically update the frame being displayed to highlight the current speaker depicted therein.
