Abstract: Due to the storage limit, the original raw video may not exist after compressing it into multiple video bitstreams using different compression parameters. In this paper, we suggest a least square error (LSE) algorithm to jointly decode the multiple video bitstreams, aiming to achieve better quality of the reconstructed video. The experimental results by joint decoding of multiple H.263 streams show that the proposed algorithm can significantly enhance the decoded video quality.
