7) Parameter for AGC reference level fine adjustment
8) Parameter for sync separation level fine adjustment
The black level is controlled. When the default is specified, the depestal position is output as a
black level (=16).

Pedestral clamp is not used.*
Pedestral clamp is used. (AGC will not operate)

6) Parameter for color subcarrier phase fine adjustment
In this block, chroma signals pass through the chroma bandpass filter to cut an unnecessary
band. To maintain a constant chroma level, UV demodulation is performed on these signals
via the ACC correction circuit. (This filter can be bypassed.)
If the demodulation result does not reach a specified level, color killer signals are generated
to fix the ACC gain. This functions as an auto color killer control circuit.
The UV demodulation result is output as chrominance signals via a low pass filter.
