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 . Operation.
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 ...
This can lead to confusion, because industry-standard SMPTE timecode formats always deal with frame rate, not field rate. 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.
01 1 = 2-way interleaved, right image on even lines; 10 1 = 2-way interleaved, left image on even lines; 11 0 = 4-way interleaved; 11 1 = side-by-side interleaved. Bit 4 = 0 Analog sync. If set, the following bit definitions apply: Bit 3: Sync type: 0 = analog composite; 1 = bipolar analog composite. Bit 2: Serration: 0 = without serrations;

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 ...
