Trellis decoding for MPEG-4 streams over wireless channels

Qingyu Chen, Koduvayur P. Subbalakshmi, Bhaskaran Vasudev, T. Russell Hsing, Andrew G. Tescher, Touradj Ebrahimi
2003 Image and Video Communications and Processing 2003  
Most video coding standards, including MPEG-4, use variable length codes to encode the discrete cosine transform (DCT) coefficients of intra frames and inter frames, and the motion vector information.  ...  Experiments indicate that the proposed decoder gives significant improvements (9 dB in some cases) for MPEG-4 video with error resilience at various channel error rates.  ...  The channel error rate is fixed at 10 −3.5 for this plot. We observe that the MAP decoder performs much better than the standard MPEG-4 decoder.  ...
