View source for 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 via DVB-T 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 [[Conexant Fusion 878A|Bt878]] in lspci:

== Howto make it work ==
=== Driver ===
The [[Conexant Fusion 878A|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 and running. 
  bttv
  bt878 
  dvb_core
  dst 
  dvb_bt8xx
If you can't find all of them, try to load them one by one with '''modprobe''', e.g.
  modprobe bt878
Now try lsmod again. 

If you can find all of them, you don't have to re-compile your kernel but can use the drivers/modules right away (see below). Otherwise: 

==== 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. :)
