Abstract
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 a coded information signal, graphic codes including picture information occupying N (N being a natural number equal to or greater than 2) channels and inserted as the subcode of the coded information signal are recorded on the recording medium. One of the graphic codes which occupies one of the N channels consists of at least a code train group obtained by arranging consecutively a plurality of code trains which relate to a series of information obtained by said coded information signal and include picture information of the same picture. At the time of playing of the recording medium, only one of the graphic codes occupying the one of said N channels is stored in a memory in response to a command and a picture signal corresponding to contents stored in the memory is generated.
