Dual Frame Motion Compensation for a Rate Switching Network
Overview Standard video coders often use the immediate past frame as a reference frame with motion compensation for video encoding. In this paper, a dual reference frame motion compensation is used in the context of high bandwidth to low bandwidth switching such as from an Ethernet connection to a GPRS system. The implementation is based on MPEG-4. Simulation results show that there is a significant gain in the PSNR for relatively static video sequences.
