Apparatus and method for transferring video data

摘要

Overlay display can be performed correctly even in a heavy load state regarding video data amount on a general purpose bus. The video data transfer apparatus of the present invention comprises an FIFO memory for video data and outputting a nearly-full signal when held data become close to full and a transfer control section stopping an output enable signal so as to stop output from the FIFO memory at the time of output of the nearly-full signal and restoring the output enable signal so as to perform control in which the video data on and after an output stop position are outputted from the FIFO memory when the same position as the output stop position appears in a frame on and after the frame of the output stop time when the nearly-full signal disappears.
