The [[Hauppauge]] WinTV-HVR-1110 is a hybrid |
The [[Hauppauge]] WinTV-HVR-1110 is a [[hybrid]] [[analog TV|analog]] and [[DVB-T]] [[DVB-T PCI Cards|PCI card]] that sometimes ships in a [[Hauppauge WinTV-HVR-1100|HVR-1100]] box. |
||
The HVR-1110, however, is of triangular shape, while the HVR-1100 board is a typical rectangular shaped card. |
|||
There are significant component differences between the HVR-1100 and the HVR-1110: |
|||
The HRV-1110 uses the following components: |
|||
===Tuner:=== |
|||
* HVR-1100 - Philips FMD1216ME MK3 hybrid |
|||
* HVR-1110 - Unknown |
|||
===Video Decoder/PCI Interface:=== |
|||
* HVR-1100 - Conexant CX23880/881/882 |
|||
* HVR-1110 - Philips SAA7131 |
|||
===Demodulator:=== |
|||
* HVR-1100 - Conexant CX22702 |
|||
* HVR-1110 - Philips TDA10046 |
|||
The latest version of the card is called [[Hauppauge WinTV-HVR-1120|WinTV-HVR-1120]] under Linux. |
|||

==Installing the HVR-1110 to Work Under Ubuntu 14.04.05 LTS (Trusty Tahr)== |
|||
===1. Turn the machine off.=== |
|||
===2. Physically install the WinTV HVR-1110 PCI card in the machine.=== |
|||
===3. Turn the machine on.=== |
|||
===4. Check to see if the saa7134 driver has been properly loaded, by issuing the following command:=== |
|||
$ sudo modprobe -r saa7134 |
|||
modprobe: FATAL: Module saa7134 is in use. |
|||
This error message indicates that the module has already been loaded (and cannot be re-loaded), indicating that the module is available. |
|||
Issue the following command to validate that the WinTV HVR-1110 card has been registered as a device: |
|||
$ sudo dmesg | grep "saa" |
|||
[ 25.932079] saa7134 0000:03:02.0: DVB: registering adapter 0 frontend 0 (Philips TDA10046H DVB-T)... |
|||
This means that the WinTV card has been registered with the Linux system as device hw:0,0 |
|||
You may also want to issue the following command to verify that the dvb device now exists in the /dev directory, also indicating the saa7134 driver has been successfully loaded. |
|||
$ ls /dev/dvb |
|||
adapter0 |
|||
===5. Enable the saa7134 driver to load the firmware file needed to program its DSP Chip (/lib/firmware/dvb-fe-tda10045.fw)=== |
|||
Issue the following command to obtain and install the correct firmware file for the WinTV HVR-1110: |
|||
$ sudo apt-get install linux-firmware-nonfree |
|||
===6. Verify that the dvb-fe-tda10045.fw file has been successfully loaded=== |
|||
$ sudo dmesg | grep "tda1004x" |
|||
[ 26.020071] tda1004x: setting up plls for 48MHz sampling clock |
|||
[ 26.332041] tda1004x: found firmware revision 20 -- ok |
|||
At this point the installation of the WinTV HVR-1110 should be finished and the card ready for use. |

====Installing the Firmware==== |
====Installing the Firmware==== |
||
This card requires a firmware file (dvb-fe-tda10046.fw) for the demodulator, which can be obtained using the get_dvb_firmware perl script included in the kernel sources: |
|||
Additionally to the kernel module the firmware has to be installed. In order to do that use get_dvb_firmware, which is this perl script: |
|||
# cd /[kernel source directory]/scripts/ |
|||
# perl get_dvb_firmware tda10046 |
|||
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). |

Latest revision as of 06:09, 13 March 2017
The Hauppauge WinTV-HVR-1110 is a hybrid analog and DVB-T PCI card that sometimes ships in a HVR-1100 box.
The HVR-1110, however, is of triangular shape, while the HVR-1100 board is a typical rectangular shaped card.
There are significant component differences between the HVR-1100 and the HVR-1110:
Tuner:
- HVR-1100 - Philips FMD1216ME MK3 hybrid
- HVR-1110 - Unknown
Video Decoder/PCI Interface:
- HVR-1100 - Conexant CX23880/881/882
- HVR-1110 - Philips SAA7131
Demodulator:

Installing the HVR-1110 to Work Under Ubuntu 14.04.05 LTS (Trusty Tahr)
1. Turn the machine off.
2. Physically install the WinTV HVR-1110 PCI card in the machine.
3. Turn the machine on.
4. Check to see if the saa7134 driver has been properly loaded, by issuing the following command:
$ sudo modprobe -r saa7134 modprobe: FATAL: Module saa7134 is in use.
This error message indicates that the module has already been loaded (and cannot be re-loaded), indicating that the module is available.
Issue the following command to validate that the WinTV HVR-1110 card has been registered as a device:
$ sudo dmesg | grep "saa" [ 25.932079] saa7134 0000:03:02.0: DVB: registering adapter 0 frontend 0 (Philips TDA10046H DVB-T)...
This means that the WinTV card has been registered with the Linux system as device hw:0,0
You may also want to issue the following command to verify that the dvb device now exists in the /dev directory, also indicating the saa7134 driver has been successfully loaded.
$ ls /dev/dvb adapter0
5. Enable the saa7134 driver to load the firmware file needed to program its DSP Chip (/lib/firmware/dvb-fe-tda10045.fw)
Issue the following command to obtain and install the correct firmware file for the WinTV HVR-1110:
$ sudo apt-get install linux-firmware-nonfree
6. Verify that the dvb-fe-tda10045.fw file has been successfully loaded
$ sudo dmesg | grep "tda1004x" [ 26.020071] tda1004x: setting up plls for 48MHz sampling clock [ 26.332041] tda1004x: found firmware revision 20 -- ok
At this point the installation of the WinTV HVR-1110 should be finished and the card ready for use.
Possible applications: mythtv, ffmpeg
Installing the HVR-1110 to Work Under Fedora Core 6
The Howto applies to a x86_64 architecture running Fedora Core 6 and kernel 2.6.20-1.2933.fc6.
Installing the SAA7134 Driver
The analog tuner of the HVR-1110 runs out of the box. The kernel modules are already included in the 2.6.20 kernel. No driver installation is required. Look out for something like
kernel: saa7130/34: v4l2 driver version 0.2.14 loaded
in the /var/log/messages to make sure the driver is loaded.
Installing the SAA7134-dvb Modules
In order for the DVB-T to work an additional module, SAA7134-dvb, and the firmware has to be installed. First of all, check whether the module is already installed. Scan through
dmesg
and look out for something like
DVB: registering new adapter (saa7133[0]). DVB: registering frontend 1 (Philips TDA10046H DVB-T)...
If you find that, than the SAA7134-dvb kernel module is already installed. Please not that in this case the HVR-1110 is the second DVB card registered in the system. You see that since frontend is 1 and not 0. If kernel module is not installed, load it into the kernel like this
modprobe saa7134-dvb.
This should automatically create a folder in /dev:
/dev/dvb/adapterN
where N is an integer. The first dvb card will be numbered starting at N=0, each following card will increase N by one. Issue an
dmesg
command to check whether the kernel module has been loaded. Output should be
DVB: registering new adapter (saa7133[0]) DVB: registering frontend 1 (Philips TDA10046H DVB-T)...
Installing the Firmware
This card requires a firmware file (dvb-fe-tda10046.fw) 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 tda10046
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).
Making the Modules Load into the Kernel at Startup
In order that the saa7134-svb module gets loaded at startup add following line
install saa7134 /sbin/modprobe --ignore-install saa7134 && { /sbin/modprobe saa7134-alsa; } && { /sbin/modprobe saa7134-dvb;}
to the modprobe.conf in
/etc/modprobe.conf
Now check whether everything is working as it should. Restart the PC and check the /var/log/messages. Look out for something like:
kernel: DVB: registering new adapter (saa7133[0]). kernel: DVB: registering frontend 1 (Philips TDA10046H DVB-T)...
telling you the dvb modules got loaded. Please note that in this case the system has two DVB cards. The second one (frontend 1) is the HVR 1110.
kernel: tda1004x: found firmware revision 20 -- ok
tells you that firmware has also been loaded.
Next Step
The next step is to create a channels.conf. To this end follow the link Testing your DVB device
Notes
The HVR-1110 requires http://linuxtv.org/hg/v4l-dvb/rev/40d58d92d183 for Audio in (S-Video and Composite) and Radio support. Sound redirect (sox or arecord) is required if you use Tvtime or Xawtv, Mplayer,Mythtv can use the sound directly. For more details about redirection see Saa7134-alsa.
