Abstract:
1. An information processing apparatus comprising: an encoder configured to encode a moving picture signal, wherein the encoder is configured to: generate a prediction signal by use of one of a plurality of types of inter-prediction modes having different block sizes set as a processing unit for macro blocks obtained by dividing a to-be-encoded screen picture, the one of the plurality of types of inter-prediction modes being an optimum type of inter-prediction mode; orthogonal transform a prediction residual signal by use of one of a plurality of types of discrete cosine transformations (DCT) using different block sizes as a processing unit, wherein the prediction residual signal is obtained by subtracting the prediction signal from a picture signal of the macro block, and wherein the one of the plurality of types of DCTs is an optimum DCT; and determine a combination of the optimum inter-prediction mode used to generate the prediction signal and the optimum DCT used to orthogonal transform the prediction residual signal for each macro block, wherein the determining the combination comprises:
