摘要
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 A/V source provides video and audio data streams to the client computing device, with current speaker data embedded into the audio stream via audio watermarking techniques. The client device extracts the current speaker data from the audio stream, and then renders and displays the video while using the current speaker data to periodically update the frame being displayed to highlight the current speaker.
