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, also tested watching two channels at the same same on DVB-C and this works.

Overview/Features

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

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

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).

The supplied IR remote is not supported yet, there is generic support in the kernel module for cx23885-based DVB-cards but this does not work for this card. (modprobe cx23885 enable_885_ir=1)
