TV Field - The TV picture created in 1/16th of a second when the electron gun scans over every other line in the picture. In the States there are 262-1/2 odd-numbered lines in a field, followed by 262-1/2 more even-numbered lines. The two fields combined make a frame, which is a complete TV picture. http://en.wikipedia.org/wiki/Field_%28video%29 See the Interactive Television Institute.
