In the contining saga of my foray into the Linux-based PVR world, I had just finished describing the installation of Ubuntu 6.10 (Edgy Eft) as my base operating system (Building a PVR: Part 1<\/a>). I was able to successfully detect my USB WiFi adapter, giving me access to the Internet from the PVR computer (for updates, channel information, etc.). The next step is to actually try and watch TV.<\/p>\n

Watching TV on Ubuntu is actually a little more work than expected. Ubuntu does not come with a bundled TV tuner program (Unlike Knoppix, which uses xawtv<\/a>). As a result, its necessary to install some TV program(s), and any associated libraries or applications which might be required. I chose a couple of the more popular ones to try out, prior to installing MythTV, which is going to be the main TV program. I decided that tvtime <\/a>and xawtv have a wide base of user support and work with practically every tuner card known, so I installed them using apt-get:<\/p>\n

$ sudo apt-get install tvtime<\/strong><\/p><\/blockquote>\n

$ sudo apt-get install xmltv<\/strong><\/p>\n

$ sudo apt-get install xawtv<\/strong><\/p><\/blockquote>\n

This installed the tvtime, xmltv and xawtv packages and their supporting components. Incidentally, xmltv<\/a> is a very popular open-source program used to deliver channel guide information for practically every tv channel in every country. Very cool stuff, particularly if you have an online PVR!<\/p>\n

I then tried to watch tv. Executing tvtime from a shell gave a blank, black window – not even static (audio or video). This suggested something wasn’t working (duh!). The first step then was to see what our diagnostics said about the installed devices.<\/p>\n

I used dmesg to return information on the loaded devices<\/p>\n

$ dmesg<\/strong><\/p>\n

with the following result:<\/p>\n

Huh! From the above message, it was apparent that my cheapo, discount tv-card was detected – partially. We can see that the saa7130 indicates the presence of a Phillips saa7130-based tuner chipset (handled by the saa7134 module), while the saa7130\/alsa enables the sound from the tuner card (using module saa7134_alsa). The full name of my card is the PowerView TV Tuner Card (PCI) – PO0010, but glancing through the Windows driver disk, turned up another (posibly) supported tuner card name – FlyVideo 2000. Scrolling through our card list above, we see that the FlyVideo 2000 is card number 3.<\/p>\n

I unloaded the incorrectly working modules using<\/p>\n

$ rmmod saa7134 saa7134_alsa<\/p><\/blockquote>\n

then reloaded the tuner modules with the card parameter set<\/p>\n

$ modprobe saa7134 card=3<\/strong><\/p><\/blockquote>\n

I then executed tvtime again.<\/p>\n

$ tvtime <\/strong><\/p><\/blockquote>\n

Success! Well, 0.5 Success! I now had a picture – but no sound. A quick look at dmesg suggested the reason:<\/p>\n

It appears that I need to specify my tuner type as well. But what are the different tuner types available to the saa7134 module? Google returned a site which conveniently lists the possible saa7130-based cards and tuner types<\/a> – unfortunately, there is no way of knowing which one I have! Basically, its trial and error time. I ran the following lines over and over again, changer the tuner number each time:<\/p>\n

$ rmmod saa7134 saa7134_alsa; modprobe saa7134 card=3 tuner=0
\n<\/strong><\/p>\n

$tvtime <\/strong><\/p><\/blockquote>\n

I struck gold on tuner=43 – sound and video on Ubuntu. Sweet!<\/p>\n

A look at dmesg tells the story:<\/p>\n

Will this setup work for everyone? I doubt it – it appears that these tuner chips are so cheap that any one of a number of variants can be found in the same product. An important check is the model number and driver details. In the end, trial and error may be the most important factor in getting your own tuner card to work.<\/p>\n

So, now we have tv actually working under Ubuntu – the next (and almost final) step is to install and configure MythTV. I’ll cover that off in my next post.<\/p>\n","protected":false},"excerpt":{"rendered":"
