Abstract :
High error rate is critical to the wireless video transmission. Our paper tackles the problem of robust video streaming over error-prone channels. Basing on an autoresilient multiple-description coding method and a multi-path transmission strategy, further study is done on the computational complexity of rate-distortion optimization for video coding and transmission. A unitary-optimized operation of the whole system is then proposed after the R-D calculation. Experiment results show that video streaming with our unitary-optimized operation gains better playback quality especially when transmitted through error-prone mobile channel.
