Hi Maxime, I think that declaring PAL-B and SECAM-B as the only supported 576i norms is a bit random. Norms B, D, G, H, I, K, K1 and L (for both PAL and SECAM) are essentially identical if we're talking about baseband signals, AFAIK they only differ when those are modulated as RF signals.

From: Mateusz Kwiatkowski Add support for the following composite output modes (all of them are somewhat more obscure than the previously defined ones): - NTSC_443 - NTSC-style signal with the chroma subcarrier shifted to 4.43361875 MHz (the PAL subcarrier frequency). Never used for
