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.
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.

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 · Actually found this from the BBC ->. 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.
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 ...
Jan 18, 2024 · An electric field is a field that exerts a force on charges – attracting or repelling them. Moreover, every single charge generates its own electric field. That's why, for example, two electrons with the elementary charge e = 1.6 × 1 0 − 19 C e = 1.6 \times 10^{-19}\ \text{C} e = 1.6 × 1 0 − 19 C repel each other.
