Multiple description video coding against both erasure and bit errors by compressive sensing
We propose a novel multiple description video coding (MDVC) technique for robust video transmission via lossy networks of both packet erasure and bit errors. The new MDVC technique is designed to meet two objectives: ultra fine description granularity and low encoder complexity, which allow resource-deprived video transmitters (e.g., smart phones) to operate in time-varying adverse network conditions. These design goals are met by the signal acquisition and coding strategy of compressive sensing, and by locally adaptive sparse representation of video signals.
