Table 10 : AVO Enable selection

Since each of the horizontal ‘halves’ of the frame is only 142 lines (CCIR) or 120 lines (EIA), there is a ‘black band’ of three lines

separating the top half from the bottom half. Similarly, for timing purposes, there is a two pixel vertical black band separating the

left and right halves of the frame. (See the timing diagram below.)
