Hauppauge WinTV-HVR-1800

From LinuxTVWiki

Jump to: navigation, search

An ATSC PCIe card from Hauppauge.

Support for the card's digital TV reception capabilities (8-VSB & 64/256-QAM) is currently provided within the latest drivers from the LinuxTV Hg repository, and should make its way into the 2.6.24 kernel. Analog support for the WinTV-HVR-1800 (which is currently contingent upon the addition of such to the CX23385/7 driver) will be added in the near future, but it will likely be too late for inclusion into 2.6.24.

Full-height Version (a.k.a Medford)

WinTV-HVR-1800, Full-height

This dual tuner card is also known as model 1129 and has a Subdevice ID of 0x7800.

It features 3 RF inputs (one for analog, one for digital and one for radio). The card also sports an A/V header, which allows for additional inputs when when used with PC cases that have built in front or rear panel A/V connectors (S-Video, Composite and L/R Audio).

Components Used

This card features:

  • NXP/Philips TDA18271 (tuner for analog)
  • Microtune MT2131 (tuner for digital)
  • NXP/Philips TDA8295 (analog IF demodulator)
  • Samsung S5H1409/Conexant CX24227 (digital demodulator)
  • Conexant CX23417 (MPEG-2 encoder)
  • Elpida (RAM)
  • Conexant CX23887 (A/V Decoder & PCIe bridge)

Half-Height/Low Profile Version (a.k.a Brentwood)

When information about a "HVR-1800" model first became known, photos accompanying this news were of this low profile card. However, as it turned out, it was the full-height HVR-1800 rendition discussed above that was widely released. Whether or not this low profile HVR-1800, or a revision like it, is ever released for mass production is still unknown. In any regard, the very small quantity that were produced are indeed supported by LinuxTV drivers. This card has a Subdevice ID of 0x7600.

Components Used

This card features the same components as the later full height version (see above) with the exception that a NXP/Philips TDA8275A tuner was used for analog, as opposed to the later card's switch to the NXP/Philips TDA18271.

Making it Work

Analog

To get Analog to work, follow the steps as shown in How to build from Mercurial up to "Build the Modules" and build the driver.

After "make install" is finished and if the system has loaded the default kernel's module, unload it with:

modprobe -r cx23885

Note: I have spoken to support in the MythTV-users IRC channel and they say the driver support / MythTV combination just doesn't work, and that the driver author is aware of the issue. I really wanted analog capture to work (and I may try messing around with it) but the "official" word is that MythTV currently doesn't support this card for analog capturing... --Jherm 00:20, 8 November 2009 (UTC)

Note: This doesn't work on Ubuntu 10.10 with the 1850 pcix, It still fails to see the analog tuner. --jbecwar 30 December 2010


Firmware

Download the firmware and all the files for cx23885 from HVR-1800 Firmware (it is also a good idea to keep checking for new firmware updates from this page). Run the .sh script and it will make two files v4l-cx23885-avcore-01.fw and v4l-cx23885-enc.fw. Copy these two files into /lib/firmware/ (not /lib/firmware/2.6.26-1-amd64 as stated by the script).

Drivers

Once that's finished, load the modules with:

modprobe cx23885
modprobe tuner

Sample Kernel Output

Run dmesg and it should look something like this:

Tvtime and Mplayer

Tvtime will be used for switching channels while mplayer will be used for watching with audio. Tvtime uses /dev/video0 which is raw video signal so it can change the station. Mplayer uses /dev/video1 which is encoded mpg2 with audio. Install tvtime and mplayer with:

apt-get install tvtime mplayer

Run tvtime as normal user (tvtime -v), configure with proper settings for your region and scan for analog channels. Run mplayer with:

mplayer /dev/video1 -vo x11 -nobps -autosync 30 -forceidx -hardframedrop -vc ffmpeg12 -idle -menu -cache 16384 -cache-seek-min 50 -mc 0 -ni

If there are artifacts, unload and reload cx23385 with modprobe and restart mplayer/tvtime.

Mythtv

According to [1] analog is not supported due to driver issues

Digital

Install the firmware and driver as stated above.

For US ATSC-QAM

Get the newest wscan from here w_scan. Extract it and manually scan for frequency using the following command: (use -A1 for Terrestrial, -A2 for Cable, -A3 for both)

 ./w_scan -fa -A2 -X -cUS > channels.conf

If the file channels.conf does not have any channel names and looks like this: service_id 808:79000000:QAM_256:33:34:808 , then follow instruction as found here to get the proper channel name.

Mplayer

For use with mplayer in Debian, copy the file channels.conf to /etc/mplayer/ or ~/.mplayer/

To start watching a particular channel use the following command: (where CHANNEL is the name of the channel in channels.conf)

mplayer -autosync 30 -cache 2048 dvb://CHANNEL

HAVE FUN!
