Method and apparatus of recording and reproducing picture information on a recording medium. In addition to video format signal and a coded information signal, graphic codes including picture information are recorded on the recording medium, by inserting the graphic codes as a subcode of the coded information signal. At the time of reproduction, a signal according to the graphic codes is mixed with the video format signal. When the recording medium is played back, a portion of the video format signal corresponding to a predetermined period of the video format signal read-out from the recording medium is written in a memory, and the signal according to the graphic code is mixed with a still picture video format signal which is produced by repeatedly reading the stored content of the memory.
