ABSTRACT:
A P/S converter converts parallel digital video signals such as a luminance signal Y and color difference signals R-Y and B-Y to serial digital video signals which are written into a semiconductor memory. The serial digital video signals read from the semiconductor memory are converted in a S/P converter to parallel digital video signals. A clock generator supplies clock signals to the P/S and S/P converters, such that a phase of the clock signals for the S/P converter has a predetermined relation to a phase of the clock signals for the P/S converter. As a result, the number of input and output pins is decreased in the semiconductor memory to result in the decreased of the fabricating cost thereof.
