Analog PAL is 52�s x 576 lines. There are no horizontal pixels, since the
signal is analog. Each line is 52�s long.
The number of horizontal pixels you get when you digitize the analog signal
depends on the sample frequency. If you use the standard 13.5 Mz sample
frequency, you get 13.5 x 52 = 702 pixels/line.
