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.

What about 576i resolution? What video resolution is this and where is it used? To understand 576i, let’s take a look at analog TV and video standards.
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) per second.
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.

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 Hz (or 25p) where both fields in a frame are time coincident. In the case of 25p material the whole
Feb 18, 2011 · When an HD format is interlaced, the number generally describes field rate (1080i60 would describe 60 fields per second). • When an HD format is progressive, the number generally describes frame rate (720p60 would be 60 frames per second).
