Videodaten-Kompressionssystem und Verfahren zum Puffern von Videodaten

摘要

A method of buffering video data in a video compression system, in which a video bit stream, compressed on the basis of an international standard, is transmitted adaptively to a state of a transmission channel under a digital communication environment where a transmission speed is very low and a bit error generation rate is very high. The video data buffering method comprises the step of performing a discrete orthogonal transform operation with respect to input video data in the unit of blocks and storing the resultant coefficients in the unit of discrete orthogonal transform components.
