Adaptive video coder with dynamic bit allocation

摘要: A method of coding a video signal at fixed bit rate with use vector quantization codebook, wherein advantageous codebook updates are determined by comparing error associated first provisional frame second the frame. The uses available number bits to code unmodified whereas modified same However, codes both and bits. having smaller is selected as which will be adopted. In addition, may replaced when selected. this manner, coder adapt characteristics scene.
