Description
Cross-color reduction filter settings for luminance path
00 = Cross color reduction filter off
01 = Filter is active; transfer characteristic 1
10 = Filter is active; transfer characteristic 2
11 = Filter is active; transfer characteristic 3
Variable blanking level during vertical blanking interval is typically
identical to the value of BLNNL.
0 = PAL switch phase is nominal.
1 = PAL switch phase is inverted compared to nominal if RTC is
enabled.
0 = Luminance gain for white - black 100 IRE for PAL
1 = Luminance gain for white - black 92.5 IRE (for NTSC) including
7.5 IRE set-up of black
SECAM enable
0 = Secam encoding switched off
1 = Secam encoding switched on (PAL has to be 0)
0 = Enlarged bandwidth for chrominance encoding
1 = Standard bandwidth for chrominance encoding
0 = NTSC encoding (non alternating V component)
1 = PAL encoding (alternating V component)
0 = 864 total pixel per line for PAL
1 = 858 total pixel per line for NTSC
0 = No real time control of generated subcarrier frequency
1 = Real time control of generated subcarrier frequency
Amplitude of color burst; input representation is in accordance with
CCIR 601
White to black = 92.5 IRE, burst = 40 IRE, NTSC encoding
BSTA 0 to 2.02 x nominal
recommended value BSTA = 0x3F
White to black = 92.5 IRE, burst = 40 IRE, PAL encoding
BSTA 0 to 2.82 x nominal
recommended value BSTA = 0x2D
White to black = 100 IRE, burst = 40 IRE, NTSC encoding
BSTA 0 to 1.90 x nominal
recommended value BSTA = 0x43
White to black = 92.5 IRE, burst = 40 IRE, PAL encoding
BSTA 0 to 3.02 x nominal
recommended value BSTA = 0x2F
fixed burst amplitude for SECAM encoding
