PROBLEM TO BE SOLVED: To provide an improvement method for coded video frames, and improvements of video coders (encoders) and subscriber terminal devices. SOLUTION: An encoding method for video frames in a communication system has a step for creating video frames that is composed of continuous still frames, a step for storing frame restructure data of at least one frame as a reference frame and movement data of encoded adjacent blocks, a step for determining movement data of encoded blocks using movement vectors of one or more encoded adjacent blocks from adjacent blocks created using the stored reference frames, and a step for determining frame restructure data and movement data that indicates encoded blocks. The method can provide a specified image quality and encoding efficiency. COPYRIGHT: (C)2007,JPO&INPIT |
