<p>PURPOSE:To obtain the method to record several kinds of video signal in a common form by denoting a common measure of the number of all effective picture elements constituting one picture as L and assgning signals, which are obtained by dividing signals corresponding to one picture into LXN, to one minimum recording unit or plural minimum recording units. CONSTITUTION:Signals obtained by dividing all DCT blocks of 6 kinds of video signal into 27 or 15 are compressed to the same rate to completely equalize the succeeding recording processing system. These 27 or 15 divided signals are assigned to one or plural minimum recording units. Thereafter, one or plural bursts consisting of plural minimum recording units are constituted, and gaps and a burst including an audio signal (if necessary) and information are added to constitute one track. The minimum recording unit consists of a pattern indicating the start of the minimum unit, a discrimination code of the minimum unit, signals themselves, and a check code of a error correction code (if necessary).</p> |
