ABSTRACT:
A video encoding apparatus comprises a frame memory/predictive image generator having a first predictive mode for generating a predictive image signal by selecting a combination from among a plurality combinations of a reference image number and a plurality of predictive parameters, and a second predictive mode for generating a predictive image signal according to a predictive parameter computed based on reference image numbers of reference images and an image-to-image distance, and a variable-length encoder to select one of the first and second prediction modes by the number of reference images, and encode orthogonal transformation coefficient information concerning a predictive error signal of a predictive image signal with respect to input video signal, mode information indicating an encoding mode, motion vector information and combination of selected reference image number with predictive parameter index information indicating combination of selected reference image information.
