576i is a standard-definition digital video mode, [1] originally used for digitizing analogue television in most countries of the world where the utility frequency for electric power distribution is 50 Hz. Because of its close association with the legacy colour encoding systems, it is often referred to as PAL, PAL/ SECAM or SECAM when compared ...

PAL and NTSC. The two SDTV signal types are 576i (with 576 interlaced lines of resolution, derived from the European-developed PAL and SECAM systems), and 480i (with 480 interlaced lines of resolution, based on the American NTSC system). SDTV refresh rates are 25, 29.97 and 30 frames per second, again based on the analog systems mentioned

Jul 15, 2016 · I used the terms ‘PAL-derived’ and ‘NTSC-derived’ above, but now that we have exited the analogue domain and entered the SD/digital realm, these two main video systems can be more correctly referred to as 576i and 480i (the i denoting that it is an interlaced signal).
For example, 576i (576 interlaced lines) digital video with colour encoded as YCbCr, intended to be backward compatible and easily displayed on legacy PAL devices, is usually mentioned as "PAL" (eg: "PAL DVD"). Likewise, video game consoles outputting a 50 Hz signal might be labeled as "PAL", as opposed to 60 Hz on NTSC machines.
