IMAGE SIGNAL RECORDING APPARATUS AND METHOD

摘要

PATENT 39-0100.2464 Image signal recording apparatus and methods are provided for recording first and second image data on a record medium wherein the first image data are obtained through sampling of image signals at a first data rate and the second image data have a second data rate lower than the first data rate such that the second image data may be reproduced by apparatus operating at the second data rate. The second image data are formed from the first image data and recorded together with at least a portion of the first image data in predetermined areas of the recording medium. The portion of the first image data recorded on the recording medium is selected such that the first image data may be derived by reproducing apparatus operating at the first data rate from the second image data and the portion of the first image data. Area discriminating codes are recorded on the recording medium for identifying the predetermined areas in which the second image data and the portion of the first image data are recorded.
