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

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