Blanking Mode
The blanking mode defines how the clamp mechanism will perform. The blanking code is the ADC output
code used by the clamp mechanism as target In the Auto mode and depends on the vertical sync
identification result (50 or 60 Hz). The blanking code is determined in the 2 other modes.
00: Auto (50 Hz = Code 256, 60 Hz = Code 244) (Default)
01: Blanking code 256 (Sync tip 43 IRE)
10: Blanking code 244 (Sync tip 40 IRE)
11: Auto (Same as 00)
Auto Identification Table (Seventh and Eighth Standards)
The STV2310 can search for one of the TV standards programmed in the Automatic Standard Identification
Table (split over several registers). The Automatic Standard Identification Table has 8 entries with an order
of priority for the search. Note that in the default configuration, "No Standard" is programmed in the seventh
and eigth entries.
000: PAL BGDHI100: PAL N
001: SECAM 101 NTSC 4.43
010: NTSC M110 or 111: No Standard
011: PAL M
Reserved: Must be set to 0.
Pedestal Remove in Input signal
The PEDESTAL_REMOVE bit describes the input signal (whether a pedestal is present in the input signal
or not). This information is entered by the user. Gain and offset on the Y processing will be different
according to that bit. The pedestal remove function is active for all 50- and 60-Hz input standards. Note that
by default, it is considered that there is no pedestal in NTSC M inputs.
The pedestal remove function operates both on the CVBS and RGB flows.
0: Pedestal is present in input signal.
1: Pedestal is not present in input signal. (Default)
