VIDEO CODER HAVING SCALER DEPENDENT VARIABLE LENGTH CODER

摘要

Method and apparatus for generating variable length coded for video encoding . A plurality of memory tables contain variable length codes tailored to patterns of input video information that is likely to be input to the variab le length encoder. The patterns are determined in large part by a value of a quantizer used in video encoding. A separate memory table containing separat e variable length codes is established for each of a plurality of quantization parameter values. The quantization parameter is input to the encoder to enab le one of the memory tables and the video information is input to the enabled table to generate the variable length code.
