摘要：
An image signal processor for processing both high definition image signal with a high resolution and standard image signal with a resolution lower than that of the high definition image signal in which the high definition image signal is decomposed into a plurality of subband signals and the standard image signal, when input, is converted into a subband signal having a low subband. Each subband signal is encoded and recorded in a predetermined area of a disk. The subband signal recorded is read out and decoded for each subband and the low subband signal is reproduced as the standard image signal by converting the width of the low subband signal into the width of the standard image signal.
