From LinuxTVWiki

Jump to: navigation, search

A Philips SAA7146 based DVB-C PCI Card produced and sold by TerraTec. Uses the Philips CU1216 tuner module, well-supported by the Linux driver. CI-Interface is assembled on some cards, but not yet supported.

This card is able to deliver the full MPEG-2 Transport Stream to the host.

Some versions have A/V inputs as well.

NOTE: If you purchased a new TerraTec Cinergy 1200 DVB-C recently, you may need to read #Version 1176 was not supported.

Past problems

These problems have been fixed in the current versions of the driver. Use the command uname -sr to see what your kernel is.

Version 1176 was not supported

The new version of this card (device code 1176) was not supported before kernel 2.6.22 (released 8 Jul 2007).[1] If the command lspci -vn | grep 153b:1176 says "Subsystem: 153b:1176" instead of nothing, you have one of the these cards. Users of earlier kernels (2.6.10 or later) can gain support by installing the latest DVB kernel modules by following these instuctions: [2]

  1. Make sure you have kernel-headers, make and gcc installed. (Contact your distribution for details.)
  2. Install Mercurial. (Check if it is provided by your distribution.)
  3. Run these commands:
    1. hg clone http://linuxtv.org/hg/v4l-dvb
    2. cd v4l-dvb
    3. make
    4. as root: make install
  4. Reboot.

If (when) your kernel gets upgraded, you will need to perform these steps to regain support (unless the new kernel comes with support for the device):

  1. Run these commands:
    1. cd v4l-dvb
    2. make distclean
    3. optional: hg pull -u http://linuxtv.org/hg/v4l-dvb (updates the modules)
    4. make
    5. as root: make install
  2. Reboot.

Problems in the Berlin cable network with kernel 2.6.11.10

The Linux driver in Kernel 2.6.11.10 (dated 16-May-2005 at kernel.org) does not lock on all multiplexes of the Berlin cable network (Telecolumbus frequency allocation), e.g. this one locks immediately:

 10 Das Erste:410000000:INVERSION_AUTO:6900000:FEC_NONE:QAM_64:101:102:28106
 10 Das Erste: f 410000000, s 6900000, i 2, fec 0, qam 3, v 0x65, a 0x66

and this one not at all:

Presumed fixed by now. Might not be.

Distorted transmission

The driver had problems (distorded transmission) with some multiplexes, but they were fixed 2005-03-08, confirmed by at least two users.
