TwinhanDTV Digital Terrestrial TV Card Ter
This is about the TwinhanDTV Ter Mini, a Twinhan Budget PCI card, capabable of recieving only-digital TV and radio (DVB-T). It's also capabable of HDTV standard 1080i, which I haven't tested as there is no HDTV transmission in UK (and whole Europe) yet. Otherwise, the card works well with Linux.
On the package it says: "TwinhanDTV Digital Terrestrial TV Card Ter" but then actually on the side it's ticked "Mini Ter (Low Profile)" (and not "Ter (Standard)"). There's also a sticker saying "Model 3020C".

It comes up as Bt878 in lspci:
Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11) Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)
Howto make it work
Driver
The BT878 chip is supported by new kernel versions -- good news! :)
This is what I've done (Debian Sarge testing, kernel version 2.6.16.9). It follows the standard installation of the bttv driver for DVB as it is included in new kernels.
Use lsmod to see if you have all these modules already installed.
bttv bt878 dvb_core dst dvb-bt8xx
If yes, you don't have to re-compile your kernel but can load them right away (see below).
Kernel re-compile
In kernel configuration (make menuconfig) make sure to have:
- Under Device Drivers - Multimedia Devices - Video for Linux
<M> BT 848 [*] DVB for bt878
which is equivalent to these entries in the kernel .config file:
CONFIG_VIDEO_BT848=m CONFIG_VIDEO_BT848_DVB=y
- Under Device Drivers - Multimedia Devices - Digital Video Broadcasting Devices
<M> DVB for Linux <M> DVB Core Support
And there under DVB Core Support - Customise DVB Frontends
<M> ... something like DVB_BT8XX
which is equivalent to these entries in the kernel .config file:
CONFIG_DVB=y CONFIG_DVB_CORE=m CONFIG_DVB_BT8XX=y
And maybe (not sure if necessary) still there under ATSC
<M> Video BTCX
which is equivalent to this entry in the kernel .config file:
CONFIG_VIDEO_BTCX = m
- Under Device Drivers - Sound - ALSA - PCI devices
<M> BT878
which is equivalent to this entry in the kernel .config file:
CONFIG_SND=y etc. for sound in general CONFIG_SND_BT87X=m
(I may have missed a couple of options. Please add them.) Save the config file, compile your new kernel and restart.
Modules needed
Required modules and parameters:
bttv bt878 dvb_core dst dvb-bt8xx
Load them using modprobe.
You should now have some stuff in /dev/dvb/adapter0/
That's it. You don't need any firmware stuff. :)
