I'm not sure why they would direct you to linuxtv.org. *They* are the ones with all the information that the linuxtv community would need. > Of course I wouldn't be surprised if people will have to reverse > engineer it from the windows drivers but I thought I would mention it. > I could not find any info on this 750 HD on www.linuxtv.org regarding > where it stands. What help is needed for it? 1. Datasheets for the 750 (under NDA is fine), but they need to agree to allow them to be used to author a GPL driver. 2. Reference driver sources which can be legally incorporated into a GPL driver. 3. Firmware with a license that permits free redistribution. I attempted to work with them back in 2009 on the T316 chip (an ATSC/ClearQAM demodulator), and they couldn't provide all of the above. Perhaps things have changed since then but I doubt it (in particular, the sale of their TV chip unit to Broadcom left all sorts of unknowns regarding who owns the relevant intellectual property). Finally, even if you get the above, there still needs to be some developer who has the time/interest to do the work. While three years ago the big challenge was getting access to the datasheets, nowadays a much bigger problem is there are no developers who are both qualified and not already too busy with other work. Bootstrapping a new chip like that is probably a 50-100 hour investment for somebody who is experienced in this area, which is a fairly big chunk of time if the developer doesn't have any vested interest.
