Circuit Operating Description
Samsung Electronics 13-7
13-4 H/W demand matter
13-4-1 Main PCB H/W demand matter
Main PCB carries out record reproduction of the input of the signal into which the optical signal was
electrically changed from CCD of CAMERA LENS ASS’Y, and an AUDIO signal by DV FORMAT at
6.35mm Tape.
It consists of circuits PCB which save or DISPLAY by JEPG and MPEG4 to MEMORY STICK. It constitutes
from the CAMERA circuit BLOCK, SYSCON/SERVO BLOCK, DV_1_CHIP BLOCK, DC/DCBLOCK,
PREAMP BLOCK, PRML BLOCK, and AUDIO/VIDEO I/F BLOCK.
13-4-2 Camera circuit Block H/W requirement
The CAMERA circuit BLOCK carries out CDS->AGC->10 Bits A/D conversion of Ccd_out Signal by
which electronic conversion was carried out from Camera Lens Ass’y.
LUMINANCE and CHROMINANCE are transformed by ITU-R 656 Format.
It is made to output by DV-1 CHIP.
It was inputted into ITU-R 656 FORMAT from DV-1 CHIP. A DIGITAL EFFECT function (PB ZOOM,
PB MOSAIC, PB MIRROR) is carried out for a VIDEO signal.
Signal inputted from CAMERA LENS or DV-1 CHIP MEMORY STICK preservation / DISPLAY is
carried out by JPEG and MPEG4 FORMAT.
