摘要：
When an OSD data storage area for storing OSD data needs to be reserved, an area of a frame storage apparatus that should store macroblocks corresponding to an invisible area on a screen is allocated as the OSD data storage area. There is no degradation in picture quality. When doing so, the data reduction control unit 64 receives an instruction to reserve the OSD data storage area and discards the corresponding macroblocks. The OSD data access unit 63 writes the OSD data into an area of the frame storage apparatus that was assigned to store the discarded macroblocks.
