(mostly) Software colour video generation

This page contains a set of links to pages that are dedicated to software generation of PAL or NTSC video signals. There might be a few links later to FPGA generation. This is mainly a reference for myself as I was designing an fpga generator with used a 4*Colour-clock sample rate (rather then the 12 times that the orginal SX (PIC) Colour Pong did).
There is enough information here to allow you to write a software colour decoder for decodingthe base band composite video signal.

Description

Links

A very good set of 3 pages explaining how to generate a PAL signal with an AVR running at 4 times the Colour clock. if you want the Math for a PAL signal for FPGA or other reasons look at Page 2.

Page1 (intro)

Page2 (PAL signal maths)

Page3 (the AVR bits)

colou bar gen with av AVR, good start, but lacks good colours. (I assume that its got poor colour burst or the programmer did not use the correct U/V maths)
