Color composite video decoding with Picoscope 3206B

I recently finished an improved version of the NTSC composite video decoder previously featured here at Code and Life. With the bigger buffer of Picoscope 3206B, I was able to capture enough samples per frame to add color. A Youtube demonstration video has just finished uploading and you can view it below.

I already talk a bit about the techniques used in the new version, as well as the new features. For the readers of this blog, I’m planning a more detailed technical explanation, which I’ll put up as soon as I get the infographics for that one done.

Enjoy the show! If you want to take a look at the sources (or better yet, have a 3000 series Picoscope at hand), you can grab the source package. My code is licensed under GPL, see README.txt inside the archive for details.

Update: Technical details now published! Implementation details to be added in another post a bit later.
