CONTROL OF 2-D DCT IN VIDEO DATA COMPRESSION

摘要

The present invention relates to an operation controller of a two-dimensional discrete cosine transform (DCT) in video compression encoding. In the case of compressing and encoding a prediction error such as video compression encoding by two-dimensional discrete cosine transform (DCT), the number of DCT operations is reduced to reduce the number of videos. As it reduces the power consumption of the encoder, it is a technology with economic effects.
