REGION-OF-INTEREST CODING WITH BACKGROUND SKIPPING FOR VIDEO TELEPHONY

摘要

A method comprising: grouping successive video frames into a frame unit; encoding regions of interest (38, 40) within the respective frames in the frame unit; and skipping encoding of areas (43) that are not within a respective region of interest for at least one of the frames in the frame unit; wherein encoding includes allocating rho domain values to macroblocks within the frame based on a frame budget and a weighting between macroblocks within the region of interest and macroblocks within areas of the video frame that are not within the region of interest.
