Abstract

In this paper, we propose a multiple description coder for motion vector (MV-MDC) based on data partitioned bitstream of the H.264/AVC standard. The proposed multiple description (MD) encoder separates the motion vector (MV) into two parts having the same priority and transmits each part through an independent packet. The proposed MD decoding scheme utilizes two matching criteria to find the accurate MV estimate when one of the MV descriptions is lost. Simulation results show that compared to simply duplicated bitstream transmission, the proposed MV-MDC scheme reduces a large amount of data without serious visual quality loss of reconstructed picture.
