A USB 1.1 DVB-T device designed by Technotrend and sold by Hauppauge. Based on a Texas Instruments DSP that remultiplexes the stream into a Technotrend-proprietary USB packet format and sends it as Isochronous USB Stream over the USB Bus.
The WinTV-NOVA-T USB sports an Alps TDMB7s tuner Module, featuring a Conexant CX22700 Demodulator.
Due to the limited USB 1.1 Bus Bandwidth of about 12MBit only selected PIDs can get transferred over the USB Bus to the Host. Some High-Bandwidth Transponders don't work, HDTV receiption is not possible.
Linux driver exists. Requires a Firmware that needs to get peeled out of the Windows Driver. A similiar DVB-S device is available, the WinTV-NOVA-S USB.
Since May 2005 (or so) there's a new Nova-T USB2 which works! (see below)
Since Oct 2006 (or so) there's a new Nova-T USB2 which does not work! (see below)
New Version
Hauppauge WinTV NOVA-T USB2 - a new high speed USB2 version that works with the latest dvb-utils (DiBcom 3000P) and Linux 2.6.12rc3 kernel. Ive got it going on Slackware, so it must be easy elsewhere. Got the info via http://www.mythtv.org/wiki/index.php/Hauppauge_WinTV_Nova-T_USB2
Newer Version Oct. 2006
The newest WinTV NOVA-T USB2 has a different USB ID. The former devices had 9300 & 9301 (for cold and warm state) and the new devices have 7050 & perhaps 7051. They won't work with the existing driver, because device detection in the driver looks for 9300 or 9301.
