ABSTRACT:
A digital image data processing apparatus has a preprocessing apparatus for preprocessing the digital video data before recording-and a post-processing apparatus for post-processing the digital video data after recording. The preprocessor receives a main channel signal and a sub channel signal, compresses these signals and concatenate into a single channel image data in which the signal position does not change each field for coding by a coder. Image deterioration during reproduction is prevented by a post-processor processing the image data decoded by a decoder by reversing the process applied by the preprocessor.
