Video encoding method and apparatus and video decoding method and apparatus

摘要

A video encoding method of performing motion compensated prediction inter-frame encoding on a to-be-encoded frame by referring to a plurality of reference frames for each macroblock, comprising: generating a prediction macroblock by a linear prediction using a plurality of reference frames; encoding a predictive error signal between the prediction macroblock and a to-be-encoded macroblock and a motion vector for each macroblock; and encoding a combination of predictive coefficients for the linear prediction for each frame.
