摘要：

This is a contribution for very low bit rate video coding in real-time and software only on computers of PC class. It is based on frame replenishment with block coding using mean-removed vector quantization. No motion compensation is employed and the Ve codebook is small. Algorithms are developed to minimize the bit rate and to reduce the search complexity for the vector quantizer. The codebook is adaptive ensuring good overall quality encodings for head-and-shoulder image sequences. Results are provided for some test sequences and compared to some other state-of-the-art techniques.
