Recording medium playing apparatus which permits changes in the display

Abstract

An apparatus for playing a recording medium on which, in addition to a video format signal and a coded information signal, graphic codes including picture information are recorded as the subcode of the coded information signal. The apparatus is structured to generate, as a reading address data, data which varies sequentially by a predetermined value from a value determined in response to a command, and to write sequentially the graphic codes output from an extracting circuit into a memory and subsequently sequentially read out the graphic codes in the order of address indicated by the reading address data. With this feature, the position of the subcode image can be moved on the picture by the video format signal. According to another feature of the invention, the apparatus is structured such that a reading timing signal which has a time relationship determined by a command with respect to a sync signal contained in the video format signal demodulated by a demodulating circuit, and the graphic codes output from the extracting circuit are written into the memory and subsequently sequentially read out in a predetermined order by using the reading timing signal.
