Abstract :
We develop a unique set of techniques to support reliable and efficient video transmission over bandwidth limited mobile networks. The video coder is based on H.263 coding standard while its transmission system design is based on efficient and effective fading countermeasures and robust decoding. In particular, combined source and channel coding coupled with diversity reception substantially improves the error resilience capability of H.263 coded video as well as the efficiency of the proposed transmission system. Moreover, robust decoding is accomplished by the use of a look-ahead strategy and a combined spatial-temporal concealment. Simulation results confirm that the proposed system can yield very good visual quality and high transmission efficiency
