5. Video Configuration
CVBS/SV Input Switch, S-first Function
We have 8 CVBS/SV input pins for arbitrary order of customers’ demand. Because there is only 1 TV decoder in MT8206G,
there is only one set (CVBS or SV) through the input pins. However, we can support S-first function without any external
circuits.
CVBS Bypass Output
The pin “TP2 “ can only output the CVBS signal of the chosen input but SV input.

Digital Input Pin Swap Selection
For layout conveniently, 8206 can flexibly swap input pin:
1. If VI0~VI23 configure as 24-bits R/G/B or CB/Y/CR mode -->
8206 can do B/R or CB/CR bus swap or MSB/LSB swap.
2. If VI8~VI23 configure as 16-bits CBCR/Y mode -->
8206 can do B/R or CB/CR bus swap or MSB/LSB swap
3. If VI16~VI23 or VI8~VI15 configure as 8-bits mode -->
