ABSTRACT:
A memory device for recording input 9-bit data comprised of 8-bit video data including a predetermined invalid period and 1-bit color frame information data. A serial-to-parallel converter converts a valid data part of the 1-bit color frame information data to 8-bit data. The video data of the input data is selected when the video data is valid and the 8-bit color frame information is selected when the video data is invalid and 8-bit color frame information data is present. A memory stores the selected 8-bit data.
