Inter-description motion vector redundancy control for scalable multiple description video coding

The problem of inter-description motion vector redundancy control in scalable multiple description video coding is addressed in this paper. In the motion compensated temporal filtering (MCTF) followed by the multiple description scalar quantization (MDSQ) of texture data approach, the same set of motion vectors are repeated in both descriptions. While this repetition of motion vector data adds extra overhead, they do not contribute to self correcting of errors as in MDSQed texture data during joint decoding. The paper proposes interleaving of motion vector fields between the descriptions and MDSQ of motion vectors to obtain two correlating motion vector fields rather than repeating them. The results show superior performance of MDSQ of motion vectors compared to other approaches.
