Abstract

Video signals transmitted over error-prone wireless channels are often corrupted by bit errors. Due to their superior data recovery performance, the reversible variable length coding (RVLC) has been used as an error resiliency scheme in the MPEG-4 and H.263 video coding standards. In order to evaluate and compare the error resiliency performance of RVLC codes, we develop an error resiliency measure in this letter. Using this measure, different RVLC schemes are compared for MPEG-4 video sequences. The effects of propagating and nonpropagating errors are discussed as well.
