[Discuss-gnuradio] BTTV revisited

[Cory Papenfuss]

	Hello all... I've just recently discovered the gnuradio project, and it 
looks really quite interesting.  In particular, I've been playing with my BT878 
video capture card and saw a few (rather dated) references to using it as a 
28/35MHz ADC.  Has there been any other work along this front?

	I have hacked the card to let me capture with btaudio at (so far) the 
448kHz.  That part seems relatively easy, but certainly won't capture high 
bandwidth signals.

	I've also seen references to using v4l's /dev/vbi interface to capture 
raw frames.  Although it really seems to want to find some sort of sync to 
latch onto, I have managed to capture some semblence of a 1kHz AM sine 
modulated on TV Channel 3's carrier (61.25).

	It seems like an interesting project, and I was wondering if anyone has 
pursued it.
