Abstract

PURPOSE: To improve an error correction effect by forming a word by arranging digital data, which is obtained by converting analogue signals of plural channels in the PCM system, and combination data on a basis of prescription.
CONSTITUTION: Right signal Rn-l sampled at a time before time l is delayed in a memory by time l and is arranged on n-th left signal Ln obtained by converting analogue signals of left and right channels, etc., in the PCM system, and further, parity signal Pn-2l based on the exclusive OR between (n-2l)-th left and right signal data Ln-2l and Rn-2l is arranged, thereby forming one word. Next, a similar word including left signal data Ln+1-3l, which precedes data Ln by 3l- 1, and successive words similar to this word are arranged, and finally, a CRC check signal is arranged, thereby forming video signal data of one horizontal period. By this arrangement, a continuous error is not generated in reproducing data, and errors are discrete. As a result, the correction of reproducing data for drop-out, etc., is performed easily and surely, and the error correction effect dependent upon interpolation is improved.
