Jump to navigation Jump to search

A dual-tuner DVB-T PCIe card sold by TerraTec. This card appears to be supported from kernel 3.3 by LinuxTV drivers (not confirmed). Testing on 3.3.0 did not appear to work, while 3.4.3 works (DVB-T/C no analog). In 3.4.6 it works quite well.

Overview/Features

This is technically a very interesting card. The hardware is as follows:

  • Tuner #1: microtune mt2063
  • Demodulators #1: Micronas drx-3916k DVB-T/Analoge TV
  • Tuner #2: microtune mt2063
  • Demodulators #2: Micronas drx-3913k DVB-T/DVB-C
  • PCI Express x1 Bridge: Conexant cx23885

Inputs:

  • 1x Antenna (Coax)
  • 1x Remote (2,5 mm jack)

Package contents:

  • Card
  • Low profile bracket
  • Remote (+ AAA batteries)
  • DVB-T antenna
  • IR receiver
  • Windows Software & Installation DVD
  • Quick setup guide

Support

This card is supported from kernel version 3.3 (?). The microtune tuner was merged in kernel version 3.3 (see first submission).

The card itself was added upstream on LinuxTV's git repository on 2011-12-17 and may have been merged upstream.

The first frontend supports only DVB-T, but support for analogue TV is planned for kernel 3.4 or 3.5. The second frontend supports both DVB-T and DVB-C in a multifrontend device (spec's DVB v5 API).

Dual Tuner Support

Also, this card advertises as being a dual tuner in the sense that you can have two streams active at one frontend at the same time. This does not work on linux yet. I tried to connect both mt2063 tuners to one demodulator in the code of cx23885-dvb.c. (line 1149). This seems to work okay when scanning for frequencies but demodulating works only for the second device (only for a few seconds too). Also I'm getting the following dmesg: 

[   52.735818] drxk: Warning -22 on QAMDemodulatorCommand

                        }
                        break;
                }
                break;

Remote Control support

I got it working, a patch is in the making! The remote is transmitting signals following the NEC IR transmission protocol. The remote is used for several Terratec TV products (e.g. Terratec Cinergy S2 PCI HD). Processing of the signals is a little different than the other chipsets so you need another keymap than already available in the LIRC database at [1]. After I submit the patch I will also make my keymap available.
