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 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 updating each frame of the video to highlight the current speaker. More particularly, an A/V source provides a video stream to a client computing device that includes delta frames interspersed between the frames of the low frame-rate video. The full video frames act as keyframes, and the delta frames provide the changes needed to modify the last displayed version of the last keyframe to highlight just the region associated with the location of a current speaker. This allows the client device to operate as a standard A/V rendering and display unit.
