Summary: 
In this paper, we present an MPEG-4 decoding scheme based on reversible variable length code. The scheme is purely decoder based and compliance with the standard is fully maintained. Moreover, the data recovery scheme suggested in MPEG-4 can still be used as the default scheme. Simulation results show that the proposed scheme achieves better data recovery, both in terms of PSNR and perceptual quality, from error propagation region of a corrupted video packet, as compared to existing MPEG-4 scheme.
