[linux-dvb] Re: Adding SDI SMPTE 259M interface to DVB card

["Daniel Schmelzer" <dschmelzer@hotmail.com>]

Hi Emil--

Don't know that there is open source bridge code for the SAA7146 Bt.656 
interface.  There's plenty of open source code for the Conexant Fusion 878A 
and CX2388x chips, at least for Windows.  That's what we use for the SDI 
Silk 100/200 (through the btwincap driver and DScaler application).  That's 
also what the Immersive Holo3DGraph uses.

Good luck.

Regards--

Dan
