Samsung Electronics
13-4-6 PREAMP Block H/W Demand matter
With PREAMP Block Amp_cs from DV-1chip (Channel Block) and a PB-High signal perform Recording and
Playback operation.
In response to Recording Data of 3 Vp-p, after DRUM performing amplification operation, each signal must be
printed out in Head S/W High and the Low section, and you have to perform Recording operation. Micro
Processor to Head S/W Pulse is used, and it is Head S/W at the time of recording and playback operation.
You have to divide and output each signal in the High and Low section.
From DRUM After performing operation which amplifies 51dB of signals which became pick up, you have to
output Differential signal output in PRML Block.
13-4-7 AV I/F Block H/W Demand matter
AUDIO/VIDEO I/F BLOCK carries out a 16 BITS AD/DA input-and-output INTERFACE function for an
AUDIO signal. You have to form BEEP SOUND and a SPEAKER output signal at the time of KEY INPUT.
COLOR OSD and a MENU DISPLAY function are carried out by the function.
Y/C SIGNAL is MIXING(ed) with an input OSD signal by DV-1 CHIP BLOCK, and VIDEO COMPOSITE
SINGAL must be output by FRONT Block.
It is at ITU-R 656 about the VIDEO input SIGNAL inputted from VIDEO JACK or SUPER JACK. DV-1 CHIP It
output by Block.
