50 Hz
- 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 and SMPTE in SMPTE 259M, includes the frame rate, as in 576i/25.

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 .
Mar 11, 2008 · In general UK produced video is shot with a field rate of 50 Hz (50i) where the two fields in a frame are 20ms apart, whilst programmes shot on film or shot to look like film will have a field rate of 25
The field rate, which is 50 Hz, is sometimes included when identifying the video mode, i.e. 576i50 ; another notation, endorsed by EBU/SMPTE, includes the frame rate, as in 576i/25 . Its basic parameters common to both analogue and digital implementations are: 576 scan lines or vertical pixels of picture content, 25 frames (giving 50 fields ...
To avoid confusion, SMPTE and EBU always use frame rate to specify interlaced formats, e.g., 480i60 is 480i/30, 576i50 is 576i/25, and 1080i50 is 1080i/25. This convention assumes that one complete frame in an interlaced signal consists of two fields in sequence.

576 identifies a vertical line count of 576 and the i identifies it as an interlaced resolution. [1] The refresh rate, 50 Hz, is sometimes including when finding out the video mode, i.e. 576i50; another notation is the frame rate, endorsed by both the International telecommunications Union in BT.601 and SMPTE in SMPTE 259M to make it 576i/25 .
This is often abbreviated as 576i25 or 576i50 (depending on whose definition you follow) to be more precise about the SDTV-mode. Both terms are interchangeable and mean the same. The horizontal display resolution of a 576i picture is not fixed. Though there are 720 horizontal digital pixel data per line, of which 704 contain picture data, these ...
