ABSTRACT:
A digital video signal processor for compressing a digital video signal and recording the compressed signal. The digital video signal processor includes a black-and-white signal detector which determines whether the digital video signal is a black-and-white signal and outputs a detection signal when it is determined that the digital video signal is a black-and-white signal. A block processor shuffles the digital video signal from the black-and-white signal detector by predetermined block units. A signal compressor compresses shuffled video signal output by the block processor. A modulator modulates compressed video signal output by the signal compressor and black-and-white signal information. A controller generates a compression control signal to be output to the signal compressor and outputs the black-and-white signal information to the modulator in response to the detection signal. When the compression control signal is received, the signal compressor transform-encodes the shuffled video signal such that a color component is encoded only with a DC coefficient. As a result, a black-and-white video signal can be recorded with higher-resolution.
