Versions of the standard

The three different versions of the standard, which are all interlaced formats, are each based on a different civil conventional standard: * STANAG 3350 Class A: 875 Lines, 30 Frames/ Sec, 60 Fields/ Sec, based on RS-343 RGB, now EIA-343A * STANAG 3350 Class B, 625 Lines, 25 Frames/ Sec, 50 Fields/ Sec, based on
