576i is a standard-definition digital video mode,[1] originally used for digitizing 625 line 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 to its 60 Hz (typically, see PAL-M) NTSC-colour-encoded counterpart, 480i.
The 576 identifies a vertical resolution of 576 lines, and the i identifies it as an interlaced resolution.[1] The field rate, which is 50 Hz, is sometimes included when identifying the video mode, i.e. 576i50; another notation, endorsed by both the International Telecommunication Union in BT.601[2] and SMPTE in SMPTE 259M, includes the frame rate, as in 576i/25.
