View source for AVerMedia AVerTVHD MCE A180

The '''AVerMedia AVerTVHD MCE''' ('''A180''') is an [[ATSC PCI Cards|ATSC PCI card]] from [[AVerMedia]], and is supported under Linux since kernel 2.6.15.

==Overview/features==
In terms of its television reception capabilities, as far as it is known, this card is only capable of supporting [[DTV|digital TV]]. The exact tuner contained within the, single RF input, Alps NIM is unknown (someone would have to open up the can module in order to identify it), but it behaves as a simple tuner and works fine with LinuxTV's generic tuner driver, serving up streams from both digital OTA and cable sources. While the Alps NIM does have an order option to include an analog IF demodulator, it is believed that AVer did not exercise that option for the NIMs used on the A180, and hence analog TV reception is impossible. (Although there were, a couple of years ago, rumours about some card owners being able to receive NTSC under Windows. Nonetheless, all attempts by LinuxTV developers to detect the presence of an analog IF demodulator were negative.  Again, the only way to absolutely discern the presence or absence of such component would be to open up the can module, which is risky and may lead no further to the truth, as the IC could also very well be tucked underneath on the backside of the NIM's PCB, and proceeding any further toward this end would then require completely disassembling the NIM from the card's PCB (i.e. it's <em>not</em> worth the risk of damage to the card, nor the hassle) on the other hand, anyone with a dead card and who wishes to find out the answer for sure are welcome to report their findings on the mailing list). 

In any regard, the regular A180 card also features analog A/V inputs, though there are also some OEM versions of the card (probably intended for sale with media centre PCs from large vendors) that are stripped down and have had the A/V inputs on the card removed.

{{Note|An AVerMedia press release (Jan 8 2007, CES) mentions them demonstrating an "updated AVerTVHD MCE A180". It does not indicate what updates have been made to the card.}}

===Components used===
* Alps NIM TDHU
** tuner ? (maybe a Infineon tua6030 or tua6034 ?)
** ATI Nxt2004 (digital demodulator for 8VSB & 256/64-QAM)
* Philips SAA7135 (A/V decoder & PCI bridge)

==Making it work==

===Firmware===
This card requires a firmware file (dvb-fe-nxt2004.fw<sup id="fn_1_back">[[#fn_1|1]]</sup>) for the demodulator, which can be obtained using the get_dvb_firmware perl script included in the kernel sources:

 # cd /[kernel source directory]/scripts/
 # perl get_dvb_firmware nxt2004

Once the download is complete, place a copy of the firmware file in your /lib/firmware directory. (This directory may differ with some distros; consult your distro's documentation for the appropriate location).

<cite id="fn_1">[[#fn 1 back|Note 1:]] </cite> All devices that use the [[Nxt2004]] demodulator are currently using a firmware version from the AVerTVHD MCE (A180). As the firmware's code has not been discerned, it is unclear whether other firmwares for the Nxt2004 would have any affect on reception performance.

===Drivers===
Just use the in-kernel drivers (any kernel >2.6.15 should have the drivers included and thereby provide native support for the card).  If you wish, for whatever reason, to compile your own driver modules, you can do so by following the [[How to Obtain, Build and Install V4L-DVB Device Drivers]] instructions.

If your device is not auto detected properly (as has been reported in some user cases), create an options.conf file in the /etc/modprobe.d/ directory.  (If the file already exists, just edit the existing one)  Add the following line to the file:

     options saa7134 card=75

Note: If you have two AVerMedia A180 cards installed, change "card=75" to read "card=75,75".

===Sample kernel output===
For a properly configured device, an example of the relevant output provided by the "dmesg" command would look like:
