Abstract :
Video transmission over error-prone mobile communication channels requires higher error resiliency than required in other channels. However, most video coding schemes utilize some form of variable length data structure in order to achieve high coding efficiency, and this can result in large drops in transmission quality in mobile channels due to loss of data structure synchronization or variable length code synchronization. We propose priority-based re-ordering technology for error control and tough synchronization (PROTECTS). This scheme offers good synchronization characteristics, and an efficient unequal error protection technique for variable length codes. The outline of the PROTECTS and some simulation results are presented in this paper
