A subcode graphics reproduction control apparatus which can automatically execute fade operations between ordinary video images and graphics images. A memory for storing graphics data presenting particular images and transparency data defining transparency of the particular images is provided, the graphics data is read out in a subcode signal format from the memory according to a fade command and sent to a decoder, and with this operation a graphics video signal is generated. Also, the transparency data is read out from the memory according to a fade command, the transparency data value is gradually changed from a specified value in one direction, and a video signal input from outside and the graphics video signal output from the decoder are mixed at a mixing ratio corresponding to the transparency data. With the configuration as described above, fade operations to gradually fade out moving picture images and fade in graphics images or to gradually fade in moving picture images and fade out graphics images are automatically executed.
