Rasberry PI

Although I am not a programmer I wonder if anybody has thought or is actively working on a coder/decoder for NBTV. They appear to be stand alone and a video interface.

I have written a "proof of concept" NBTV encoder for the "Team Prometheus" project. It takes video from a Raspberry Pi camera and converts it into an NBTV audio stream (48 line 15 FPS).

The analogue audio output of the Pi is a pwm type arrangement and thus is rather low quality but, of course, you can plug in a high quality USB audio device or output digitally.

The camera I used here is of the "No IR Filter" type (Pi NoIR) - so there is a rather large IR component in the picture:

Hi, very impressive video. Very interesting to experiment on Raspberry.
Is the sourcecode available to test ?
