An information recording medium player which extracts a main code and a subcode from a read-out signal obtained by playing a recording medium; detects, as a select signal, an information bit signal in a MIDI format signal acquired by decoding the subcode, and distributes a channel message signal in the MIDI format signal to a plurality of output terminals in accordance with the select signal, thereby relatively increasing the data transfer rate.

Information recording medium player for controlling musical devices

Method of recording and reproducing picture information and a recording medium on which the picture information is recorded by the method, and an apparatus for playing such a recording medium. In addition to video format signal and a coded information signal, graphic codes including picture information and instruction codes representing a mixing ratio on each position of a two-dimensional picture formed by the video format signal are recorded on the recording medium after being inserted as a subcode of the coded information signal. At the time of reproduction, signals according to the graphic codes are mixed at each position of the video format signal in accordance with the instruction codes. Preferably, in graphic codes are preferably codes representing the color of each position of the two-dimensional picture, and the instruction codes are codes respectively representing mixing ratios previously determined in accordance with colors represented by the graphics codes.

Method of recording and reproducing picture information, recording

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.
