摘要：
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, the 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.
