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.

As Tuner Module a Alps TDMB7 with CX22700 Demodulator (made by Conexant Systems, Inc.) is used.

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.
