    摘要: It is an object to improve coding efficiency by suitably setting, with respect to input information in moving image coding, a parameter for quantization calculation at the time of quantization. Various parameters for quantization calculation are set by a parameter setter 103, quantization is performed with the set parameters for quantization calculation by a quantizer 102, a coding cost J is calculated from a generated code amount R and a quantization distortion amount R obtained as a result thereof, and a parameter judgment unit 107 for quantization calculation selects, as a parameter for quantization calculation having highest coding efficiency, a parameter by which the coding cost J becomes minimum.

    摘要: A video encoding apparatus includes selecting one combination, for each block of an input video signal, from a plurality of combinations. Each combination includes a predictive parameter and at least one reference picture number determined in advance for the reference picture. A prediction picture signal is generated in accordance with the reference picture number and predictive parameter of the selected combination. A predictive error signal is generated representing an error between the input video signal and the prediction picture signal. Encoding the predictive error signal, information of the motion vector, and index information indicating the selected combination is included.
