Jay Salsburg jsalsburg at bellsouth.netI wonder if anyone has studied these products? The Tuner chip in the Hauppauge WinTV-HVR-950Q hybrid TV stick appears very powerful, is used in many popular Televisions around the world. Hauppauge makes PCI-based Tuner cards that are also very powerful. Since the Tuner Chips in these products are I2C controlled, it would be very easy to control them with a BUSPIRATE. Demodulation of narrowband I/Q signals could be accomplished with a SoundBlaster Audio Card. http://www.crestatech.com/pdf/XC5000_prodbrief.pdf http://www.crestatech.com/pdf/XCV-EVP_prodbrief.pdf http://www.hauppauge.com/site/products/data_hvr950q.html These are the Specifications for the XC5000 Tuner Chip used in the Hauppauge WinTV-HVR-950Q hybrid TV stick.
