Example 3
4.3.1 Assumptions
Input connector:
Component [VI_1_B (Pb), VI_2_B (Y), VI_3_B (Pr)]
Video format:
NTSC (J, M, 443), PAL (B, D, G, H, I, N, Nc, 60) or SECAM (default)
Output format:
20-bit ITU-R BT.656 with discrete sync outputs
4.3.2 Recommended Settings
Recommended I2C writes: This setup requires additional writes to output the discrete sync 20-bit 4:2:2 data,
HS, and VS, and to autoswitch between all video formats mentioned above.
