Circuit Operating Description
13-4-4 DV-1 Chip Block H/W demand matter
DV_1 CHIP BLOCK is AV I/F BLOCK to a CAMERA circuit or a VIDEO signal at the time of Record MODE.
Function . which inputs by ITU-R 656 FORMAT, SHUFFLING(s), and sends RECODING DATA by PREAMP
Block.
At the time of TAPE reproduction, PRML BLOCK to 41.5 Mhz PB_CLK and PB_DATA are inputted, and ECC
DECODING, DECOMPRESSION, and a DESHUFFLE function are carried out, and it is again inputted into the
CAMERA circuit BLOCK after output VIDEO DATA by ITU-R 656 FORMAT, and is with VIDEO Y/C SIGNAL
to AV I/F BLOCK. You have to carry out the DATA communication function which sent and carried out
