A Novel Multiple Description Video Codec Based on Slepian-Wolf Coding

One major task in multiple description video coding is to prevent drift on packet loss channels, where transmission errors occur in each description. We propose a distributed multiple description video coding (DMDVC) scheme excluding any prediction loops. The new codec suffers from no drift problem. In the two-channel mode of symmetry side informations (SI), one side decoder can use the SI of the other without any decoding quality degradation. Thereby, DMDVC achieves high robustness on packet loss channels.
