Multiple Description Video Coding Over Multiple Path Routing Networks

This paper presents a Multiple Description (MD) video-coding scheme, which uses interlaced High Signal to Noise Ratio (H-SNR) and Low Signal to Noise Ratio (L-SNR) coded frames to produce two bit-streams. At the decoder, when both bit-streams are received a high quality video will be reconstructed. If either one is received, a poorer but acceptable quality video can be reconstructed. In this approach, the authors also considered the mismatch between the encoding and decoding loops due to motion compensation if only one bit-stream is received. They first give the results of the rate distortion performance of their scheme assuming that only one description is received.
