We propose an error-resilient transmission technique for the H.263 compatible video data stream, based on the data partitioning technique. The proposed algorithm employs the bit rearrangement technique in each layer, which provides unequal error protection against the channel errors, without requiring additional side information. In addition, we propose a recovery algorithm for the lost or erroneous motion vectors. The proposed algorithm is implemented, based on the H.263 standard, and evaluated through intensive computer simulation. The experimental results demonstrate that the proposed algorithm provides acceptable performance both subjectively and objectively at various bit error rates and burst lengths
