Abstract

PURPOSE:To ensure a high-quality record/reproduction of the digital signal, by dividing the odd-numbered sample of the quantized digital signal into N/2 blocks (even number of N>=2)and then setting a channel in every block. CONSTITUTION:The color video signal is quantized at the A/D converter 13 and with the sampling frequency 4fc and then turned into the 768-sample digital signals D1-D768 with every effetive data in each horizontal period. And the 192- sample signals D1-D383 of the odd number in the first half of the signals D1- D768 are distributed to the channel A. And the latter-half odd-numbered 192-sample signals D385-D767 are distributed to the channel C. Furthermore, the first-half even-numbered 192-sample digital signals D2-D384 are distributed to the channel B along with the latter-half even-numbered 192-sample signals D386-D768 distributed to the channel D respectively. In such way, a high-quality record/reproduction of digital signals is ensured by trimming the carrier color signals during a high- speed searching.
