can someone please explain this simple matter to me ?

so i am confused about a certain part of the PAL video signal , i am attempting to generate a monochrome pal video signal , i did this before but lost the diagrams i used , i just cannot find some decent intel in the web that exactly describes the blanking period and how many short pulses and broad pulses are needed there . thank you

Have you seen this?

There is an Arduino library for "TVOUT", which can generate monochrome 128x96 pixel resolution for NTSC or PAL:
