ABSTRACT:
A jog method for viewing video signals frame-by-frame during a reproducing stage in an optical disk player using an optical disk which rotates at a constant linear velocity as a video recording medium involves steps for providing jog mode data to a microcomputer via a key input, generating a jog play control signal to perform a jog play, reproducing signals of one track on a disk via a pickup by the control signal, and displaying a video signal of one field to display a video signal of only one frame if a vertical sync signal or picture number data of a first odd-numbered field video signal exists among video data input to a microcomputer, and shifting the pickup by one track to the next track on the disk to reproduce signals of the next track. Accordingly, the jog function can be realized without using a high-priced memory.
