Abstract
This invention is a method to automatically configure the universal variable length coding (UVLC). The method is applicable to code the syntax elements with a lot of symbols like the transform coefficients and motion vectors. The configuration problem includes a configuration method based on a genetic algorithm (GA). The method can be applied to on-the-fly configuration of codewords during video encoding, or to off-line training of code tables. This invention also includes several techniques to reduce the required operations for applications which have only limited processing power.
