Abstract

PURPOSE:To execute a YC separation extending over almost whole data block, by separating both end parts of a data block by a lower filter, and separating its remaining part by a higher filter. CONSTITUTION:In case when a YC separation is executed by providing a digital color video signal to a digital filter, prescribed pieces of data of both end parts of a data block are separated by a lower digital filter 4, and remaining data are separated by a higher digital filter 3. For instance, a digital color video signal S which has been reproduced by a VTR is provided to an input terminal 1, and is temporarily written in into a frame memory once. The signal S which has been read out from the memory 2 is provided to the higher filter 3, the lower filter 4, a lower part discriminating circuit 5 and a line ID discriminating circuit 6, and an output is changed over by multiplexers 7, 8 in accordance with a discriminating signal from the lower part discriminating circuit 5.
