In the UK PAL-I system, the single color subcarrier is 4.43361875 MHz above the video carrier. The video bandwidth is 5.5 MHz and the audio carrier is 6 Mhz. In the French SECAM-L system, the colour subcarrier is split between two different frequencies, 4.250 MHz and 4.40625 MHz above the video carrier. The video bandwidth is 6 MHz and the audio carrier is 6.5 MHz
That's a good point, but I'm not using the TV out, so haven't bothered with that. I'm hoping to replace the modulator with a c0pperdragon board to get YUV output I can feed into an RGBtoHDMI.

What about SECAM to PAL conversion?
