Abstract
A video call host module comprising a processor configured to decode video data corresponding to videos from endpoints and rank the videos based on motion indicators corresponding to each of the endpoints. The motion indicators are calculated from motion vectors corresponding to each of the videos. A predetermined number of highest-ranking videos are selected for display. A method of hosting a video call includes receiving encoded video data including motion vectors. Videos are ranked based on a motion indicator calculated from the motion vectors for each of the videos. Encoded video data is converted to decoded video data, and decoded video data corresponding to a predetermined number of the highest ranking videos is combined to create a single video.
