In this paper, we propose an error resilient transmission system for reliable transmission of H.263 coded video sequence over mobile networks. Both the coded video characteristics and mobile channel statistics are investigated. The error protection schemes are designed based on the best matched block codes coupled with diversity reception. A low complexity error concealment based on prediction of inter-block correlation is also introduced to effectively reconstruct the damaged image blocks caused by the residual errors. Simulations with different test video sequences under various mobile channel conditions confirm that good visual quality can be achieved by the proposed system
