Never used for broadcasting, but sometimes used as a hack to play NTSC content in PAL regions (e.g. on VCRs). - PAL_N - PAL with alternative chroma subcarrier frequency, 3.58205625 MHz. Used as a broadcast standard in Argentina, Paraguay and Uruguay to fit 576i50 with colour in 6 MHz channel raster. - PAL60 - 480i60 signal with PAL-style color at normal European PAL frequency. Another non-standard, non-broadcast mode, used in similar contexts as NTSC_443. Some displays support one but not the other. - SECAM - French frequency-modulated analog color standard; also have been broadcast in Eastern Europe and various parts of Africa and Asia. Uses the same 576i50 timings as PAL. Also added some comments explaining color subcarrier frequency registers.
