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.
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;
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 ...
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
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.

576i. 576i is a standard-definition digital video mode, [1] originally used to make analog television digital in most countries where the utility frequency for power distribution is 50 Hz. Because of its association with older colour encoding systems, it is often referred to as PAL, PAL/SECAM or SECAM when compared to its 60 Hz NTSC colour ...
