If you intend to use the tuner on a regular basis and are stuck with the 2.6.27 kernel, you may wish to add an entry anywhere in a file in /etc/modprobe.d/ |

This will probably be fixed in later versions of the kernel. |

Now, plug in the tuner and type |

which automatically loads the module with the specified parameter. This will probably be fixed in later versions of the kernel. |

===Sample Kernel Output=== |

you should see a series of lines that read something similar to the following: |

If you intend to use the tuner on a regular basis and are stuck with the 2.6.27 kernel, you may wish to add an entry anywhere in a file in /etc/modprobe.d/ |

options pvrusb2 initusbreset=0 |
|||
which automatically loads the module with the specified parameter. |
|||
Now, if you plan on viewing ATSC/QAM channels, you will need to scan for them. Full details on the following section are found here ([[Scan]]). The scanning program simply sets the frequency of the DTV tuner and then looks for signal. Because of the wide array of frequencies used in different countries, in order to scan you need a scan file that contains the frequencies used in your country. Common locations for these files are: |
|||
/usr/share/dvb/ |
|||
/usr/share/doc/dvb-utils/examples/scan/ |
|||
/usr/share/doc/dvb-apps/ |
|||
/usr/local/share/dvb/scan/ |
|||
On Ubuntu 8.10, the default scan files are contained in "/usr/share/doc/dvb-utils/examples/scan/dvb-t/". After you find the location of the files, browse through the subdirectories to find the scan file that applies to your location. In the case of US ATSC, the file is located in "/usr/share/doc/dvb-utils/examples/scan/atsc". |
|||
With the scan files, you are now ready to scan for stations. On Ubuntu 8.10, the DTV scanning program is called "scan," but it may be called "dvbscan" on other systems. To scan for US ATSC channels: |
|||
$ scan /usr/share/doc/dvb-utils/examples/scan/atsc/us-ATSC-center-frequencies-8VSB |
|||
Similarly, for QAM encrypted cable, you can use |
|||
$ scan /usr/share/doc/dvb-utils/examples/scan/atsc/us-Cable-Standard-center-frequencies-QAM256 |
|||
Now, we need to store the output from the scan file for use by other programs. If you wish to receive ATSC OTA stations, you would use the .azap directory: |
|||
$ mkdir ~/.azap |
|||
$ scan /usr/share/doc/dvb-utils/examples/scan/atsc/us-ATSC-center-frequencies-8VSB > ~/.azap/channels.conf |
|||
For countries that used dvb-c, dvb-s, or dvb-t, refer to [[Scan]] for more information. While scan is running, you will see output on your screen similar to the following: |
|||
<pre> |
|||
scanning /usr/share/doc/dvb-utils/examples/scan/atsc/us-ATSC-center-frequencies-8VSB |
|||

|||

|||

|||
WARNING: filter timeout pid 0x1ffb |
|||
</pre> |
|||
Clearly, stations that work are prefixed by "service is running." Stations that have poor reception or have other technical difficulties often time-out. |
|||
For me, my channels.conf file looks like this: |
|||
<pre> |
|||
KUSA-HD:485028615:8VSB:49:52:1 |
|||
WX-Plus:485028615:8VSB:65:68:2 |
|||
KMGH-HD:491028615:8VSB:49:52:3 |
|||

|||
... |
|||
KCEC-DT:695028615:8VSB:49:52:3 |
|||
</pre> |
|||
The text at the beginning is a user-defined string (with no spaces) that will be used to identify the station later. If you have gotten this far, your tuner is working properly. |
|||
Now, the LinuxTV Wiki suggests using a program called zap to test your tuner (see [[Zap]]). For ATSC, we use azap. If I wished to tune KUSA-HD from the above list, I open a shell and type: |
|||
$ azap -r 'KUSA-HD' |
|||
For which I receive |
|||
<pre> |
|||
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' |
|||
tuning to 485028615 Hz |

|||
status 1f | signal bbee | snr 19b1 | ber 00000000 | unc 00000000 | FE_HAS_LOCK |
|||
</pre> |
|||
Full documentation on the meaning of these columns is found on the LinuxTV Wiki, [[Zap]]. The important columns are the status column (00 means the tuner is initialized, but nothing has been decoded, 1f means tuning is working) and the last column (FE_HAS_LOCK means everything is working). Sadly, I was not able to get any of the suggested testing methods to work (see [[Testing_your_DVB_device]]), but I did find that xine works with ATSC stations. |
|||
To watch DTV, install xine (on Ubuntu, sudo apt-get install xine-ui) run it to create the configuration directory, and then copy the channels.conf file over to the .xine directory: |
|||
$ cp ~/.azap/channels.conf ~/.xine/ |
|||
==External Links== |
|||
Now, launch xine and click on the DTV button. Using the playlist, you can change between stations. |

- Infineon TAU6034 (tuner)'
- NXP/Philips TDA9887 (analog demodulator)
- LG DT3303 demodulator (digital demodulator)
- NXP/Philips SAA7115HL (A/V decoder)
- Cirrus cs53l32a (audio decoder)
- Lattice LC4128V
- Cypress FX2LP (CY7C68013A) (USB bridge)

Firmware
The analog portion of the driver is using firmware for Hauppauge WinTV-PVR-USB2 MPEG2 Encoder/Tuner (you can observe this in the dmesg output provided below).
Drivers
A change in the 2.6.27 kernel broke a portion of the pvrusb2 module. Until this issue is resolved, it is necessary to load the module manually before connecting the tuner to your computer:
$ sudo modprobe pvrusb2 initusbreset=0
If you intend to use the tuner on a regular basis and are stuck with the 2.6.27 kernel, you may wish to add an entry anywhere in a file in /etc/modprobe.d/
options pvrusb2 initusbreset=0
which automatically loads the module with the specified parameter. This will probably be fixed in later versions of the kernel.
Sample Kernel Output
Output from dmesg:
