BETACAM, Enable BETACAM Levels, Address 0x01 [5]
If YPrPb data is routed through the ADV7188, the automatic
gain control modes can target different video input levels, as
outlined in Table 44. Note that the BETACAM bit is valid only if
the input mode is YPrPb (component). The BETACAM bit sets
the target value for AGC operation.
A review of the following sections is useful:
•
•
The automatic gain control (AGC) algorithms adjust the levels
based on the setting of the BETACAM bit.

The INSEL [3:0], Input Selection, Address 0x00 [3:0]
section describes how component video (YPrPb) can be
routed through the ADV7188.
The Video Standard Selection section describes the various
standards, for example, with and without pedestal.

PW_UPD, Peak White Update, Address 0x2B [0]
The peak white and average video algorithms determine the
gain based on measurements taken from the active video. The
PW_UPD bit determines the rate of gain change. LAGC [2:0]
must be set to the appropriate mode to enable the peak white or
average video mode.
For more information, refer to the LAGC [2:0], Luma Automatic
Gain Control, Address 0x2C [6:4] section.
0—Updates the gain once per video line.
1 (default)—Updates the gain once per field.
