6.5.4 Window generator
The figures below show the functionality of the horizontal and/or vertical window function. The
actual TV display can be overwritten with a constant value (defined by YBORDER, UBORDER,
VBORDER), which is called “closing” or the constant value can be overwritten with the actual TV
signal, which is called “opening”. For the generation some parameters exist, which will be explained
in more detail afterwards.
