- W1607300445 abstract "In wireless video broadcast system, analog joint source-channel coding (JSCC) has shown advantage compared to conventional separate digital source/channel coding in the aspect that it can avoid cliff effect gracefully. What's more, analog JSCC only needs a little calculations at the encoder and has strong adaptability to different channel condition, which is very suitable to the wireless cooperative scenario. Thus in this paper, we propose a distributed cooperative video coding (DCVC) scheme for wireless video broadcast system. The scheme is based on the transmission structure of Softcast and borrows the basic idea of distributed video coding. Different from the former cooperative video delivery methods, DCVC utilizes analog coding and coset coding to avoid cliff effect and to make the best of transmission power. The experimental results show that DCVC outperforms the conventional WSVC and H.264/SVC cooperative schemes, especially when the cooperative channel is worse than the original source-terminal channel." @default.
