The following three charts outline popular current analog and digital television production standards. The last is known as the ATSC Table 3 transmission standards for the USA.    Note: These formats are known as the 18 "ATSC Table 3" formats. Each frame rate has a frequency change to accommodate NTSC color (24=23.98, 30=29.97, 60=59.94), for a total of 36 formats. The fractional frame rate will remain part of the DTV landscape until NTSC is no longer needed. ATSC Table 3 formats are not required, and broadcasters can legally transmit any format they choose. Simplified ATSC Standards Chart
* = All frame rates also allow for fractional "NTSC compatible" versions. It is interesting to note that the lowest quality format that is accepted under the new standard is the highest quality we knew formerly, 640x480 interlaced. And the highest quality is a specification for which NO equipment is yet available, 1920 x1080 progressive (although Sony's new Cine Alta camcorder comes very close).
