Hi,
To get analog tv working on a hauppauge hvr-930c, I started sniffing usb and
parsing.
you can see a sample here :
https://dl.dropbox.com/u/93775123/grphCable22.txt
Howeverver I am missing a lot of knowledge to jump on it right away, so I'd
as for opinion of the experts over here first.
AFAIKT, the designs with avf4910b also has a drx-k demod on it (or maybe some
other Micronas demod, like drx-j).
When I added support for Terratec H7, I used a Linux driver made available by
Terratec at that time, as reference. See:
http://lwn.net/Articles/476992/
While I don't see the link for the driver anymore on Terratec linux site,
it seems that the file is still there at:
http://linux.terratec.de/files/TERRATEC_H7/20110323_TERRATEC_H7_Linux.tar.gz
While H7 driver there only adds support for digital TV, you may find
something useful at drxk driver, as it has several stuff there related
to analog TV. I won't doubt that the needed bits for avf4910 are (at least
partially) there. So, you may find useful to take a look on it.
To be frank, while I would love to have analog working there, I never
found enough time to work on adding analog support for it, nor I succeeded
to get any avf4910b datasheet or development kit.
This could be benifical for several other cards with the avf4910 as well.
Sure. I suspect that, once having it work for one device, it should be
trivial to make it work with the others.
thx,
Jan De Graeve

Hi,
Thanks for the pointers, the code for the audio demodulator is in the drx-k
driver. I updated the comments accordingly in
https://dl.dropbox.com/u/93775123/grphCable22.txt
I am updating that file it as I find more things.
Any other suggestions/comments or anyone wanting to work with me on this ?
It would be a pity if these boards did not get analog support.
regards,
Jan De Graeve
