Abstract
A method and apparatus for adaptively selecting a coding mode for video encoding systems using the techniques of predictive coding, interpolative coding, motion compensation, discrete cosine transformation (DCT), adaptive quantization, or variable length coding. In one system, a value related to an amount of total code, which is composed of current video code and its coding parameters for each of the above coding modes, is determined, respectively, and a coding mode corresponding to the smallest value is selected. Then, the encoding is performed using the selected coding mode.
