A DVB-T USB 1.1 device designed by TechnoTrend and sold by Hauppauge.
It is supported under Linux.
Overview/Features
This device is a rebadge of the DVB-T member of TechnoTrend's TT-PCline USB family of devices, which were USB1.1 based and of the, so called, "budget" category.
It uses a Texas Instruments DSP that remultiplexes the stream into a TechnoTrend-proprietary USB packet format and sends it as Isochronous USB Stream over the bus.
Due to the limited bus bandwidth provided by USB 1.1, of approximately 12Mbps, only selected PIDs can be transferred over USB to the host system. Consequently, some high bandwidth transponders won't work, and HDTV reception is not possible.
Components Used
- Alps TDMB7s tuner Module
- featuring either a Conexant CX22700 or NXP TDA10046 (demodulator )
- a Texas Instruments DSP (USB bridge)

Making it Work
Firmware
Requires a Firmware, dvb-fe-tda10046.fw, that needs to get peeled out of the Windows Driver.
Drivers
The following drivers are needed for these devices:
- cx22700.ko - tda1004x.ko - dvb-ttusb-budget.ko
