Abstract

Abstract A code signal (DSCD) for controlling the playback of the video disk is added to each video frame of a video signal in a predetermined period thereof, and the video signal, which includes the added code signal, is recorded on a video disk. The code signal includes a video frame number code (UFN) representative of successive values from a lead-in area through a program area to a lead-out area of the video disk, and may additionally includes identification information (ADST) for identifying each of the lead-in, program, and lead-out areas to which the video frame number code belongs. Typically, the video signal is a MUSE signal. The predetermined period is an undefined horizontal scanning line period.
