PIC PAL video

How to turn a PIC18 into a B&W Text & Graphics PAL video processor with a very few and inexpensive hardware, and a minimum of coding effort?
Since the video screen has to be mapped in memory, only PICs with enough RAM are concerned, that's why the PIC PAL Library is for PIC18 family only. The PIC must be clocked at 32 Mhz with a 8 Mhz crystal, to get the 64 µs horizontal synchronization timing of the PAL system.
The library generates a 625 lines interlaced PAL video signal, and can display up to 248 vertical lines of 128 pixel. Any video display device with a PAL video composite input should be able to display the picture generated by the PIC.
