RESUMO

Very low bit rate coding below 64 kbit/s will be an important issue in forthcoming visual services such as videophone and multimedia systems. The trend of increasing interest in, and demand for, mobile phone, interactive TV and multimedia services, has led to significant acceleration of video coding research worldwide. This paper introduces and presents simulation results of an error canceling technique and synchronization recovery with the H.263 decoder for improving the quality of decoded video at very low bit rate. The paper concludes with a discussion on future directions regarding possible improvements to the coding algorithm
