Abstract
During optical disk recording of a digital coded video signal, the numbers of infield or inframe encoded data frames or their address information are stored in an innermost or outermost region of an optical disk, and during playback, they are first retrieved for use as control data. Since the numbers or address information of the infield or inframe encoded data frames are acquired, a specific playback mode, e.g. high-speed playback or still picture reproduction, can readily be executed with advantageous effects through searching the address information.
