METHOD AND APPARATUS FOR MOTION BASED PARTICIPANT SWITCHING IN MULTIPOINT VIDEO CONFERENCES

摘要

In one embodiment, an apparatus comprises a memory that stores executable instructions and a processor that executes the instructions in order to determine, for plural received compressed video inputs, at least one motion vector included in each of the plural compressed video inputs; calculate, based on the determined motion vectors, a motion value corresponding to each of the plural compressed video inputs, the motion values representing a level of motion over several frames for each of the plural compressed video inputs; and select, based on the calculated motion values, at least one of the plural compressed video inputs to be displayed.
