Hauppauge DEC2000-T USB

A DVB-T USB 1.1 device from Hauppauge (actually manufactured by TechnoTrend) that can be used either as a PC peripheral or as a standalone STB.

Linux driver exists, Audio and Video work.

Overview

 Card can only deliver a partial/modified TS stream to userspace.
 Card has an onboard hardware video+audio decoder.
 card driver: ttusb-dec
 interface: USB1.1
 USB device id: 0b48:1008
 Notes: These cards have the frontend hidden behind a USB interface  

Based on the AV711x MPEG2 Decoder and the TDA10045 Demodulator.

It will not work with VDR as a primary device because it does not have a hardware MPEG2 decoder. It can be used with soft-device, streaming or xine or as secondary device.

I have not been able to find a CAM for Top-up TV in the UK despite Hauppauge providing them for other models. There is space for a CAM in the version of the hardware supplied with the 1.26 firmware.

The DEC is a set-top boxes equipped with a USB port and can be used without a PC. The TV-Out can't be used for PC output.

The following drivers are needed for this device:

 - ttusbdecfe.ko
 - ttusb_dec.ko

Under Debian

• Follow the instructions in /usr/src/kernel-source-2.6.8/Documentation/dvb/.
• Use v1.26 of the firmware. Look on archive.org and use zip -F after download if necessary. The most recent version (1.28a?) did not work for me.
• Install dvb-utils
• Playback and channel changing (via the playlist) is possible with gxine.
  • Set up the channels with

scan -o zap /usr/share/doc/dvb-utils/examples/scan/<country>-<region> > ~/.xine/channels.conf

• • I've had problems with the picture not displaying, but that could be a driver problem.
• You can record programs with

tzap "Channel id" -r & cat /dev/dvb/adapter0/dvr0 > "Programme.mpeg" &
