Talk:TV tuner card
|This is the talk page for discussing improvements to the TV tuner card article.|

"Use of TV cards is high amongst university students in western countries due to the demands of university work making personal computers very popular, the general lack of space in university accommodation and the cost of buying a separate television."
I'm not sure this is particularly interesting or relevant.
"These computer components are likely to fade from use should broadcast television continue it's slow decline in favour of Internet distributed content (though television itself is unlikely to follow such a decline due to the prevelence of cable and satellite television and the convergence of television, hi-fi systems, gaming systems and personal computers into "Home Entertainment Systems")." --18.104.22.168 19:25, 1 December 2006 (UTC)
- Surely this is just inaccurate? I think this is confusing the purchase of a separate TV Card with TV Cards as a piece of hardware built into the machine. Surely TV cards will increase in numbers as they become standard components within the hardware showing the 'internet distributed content'? --bodnotbod 13:56, Apr 30, 2004 (UTC)
- No. I just bought a brand new computer and it did not have a TV card. You still have to get it installed manually or use an external card, like I do. Mike H 18:36, Oct 27, 2004 (UTC)
It is true, all to say that a TV tuner is a PC accessory. A TV tuner is a circuit (does not have to be an independent device) that takes an radio frequency signal and tunes it to a certain frequency (tv channel.) A TV tuner is present in many devices, including but not limited to TVs (of course), VCRs, DVRs, and, as we all know, PC tv tuner cards. —The preceding unsigned comment was added by Anoncompboy (talk • contribs) 05:57, 17 December 2005 (UTC)
- This article is about the "TV tuner card", which is apparently different from a "TV tuner". Possibly, a separate article should be created, or this one changed to encompass both the general meaning and this particular applications. —Centrx→talk 21:26, 19 June 2006 (UTC)
Needs a section to define OS requirements
On some kinds of TV card Tuners, OS requirements are very strict. In Windows Media Center edition their are only a hand full of TV Tuner Cards that are compatible with the Windows Media Center. and of course with mac their are other problems with requirements. --Gakhandal 06:56, 31 August 2006 (UTC)
- This almost entirely has to do with drivers, I think, and almost nothing to do with what operating system happens to be in use. Theshibboleth 06:31, 30 October 2006 (UTC)
- Two almosts, but very important almosts. To have a driver is not enough to have it work with certain Systems, like the aforementioned Media Center. You'll need a signed driver, i.e., a driver that's been approved by the system manufacturer. There are documented cases where that kind of approval has been denied. --22.214.171.124 (talk) 10:02, 12 December 2007 (UTC)
Updated introductory section
I've rephrased the first section, brought it up to date, and removed a lot of stuff that doesn't really belong there and that is described better where it does belong.
What's still missing (apart from the OS requirements section that Gakahndal mentions) is a section describing the architecture of such a card. I'm thinking of writing one, but it'll take a while. If anybody else is working on this, please contact me via email. Groogle 02:35, 29 April 2007 (UTC)
UK TV ("BBC") Licence Requirements...
I wonder if anyone has ever asked a TV Licensing inspector if it's technically legal to exploit what appears to be a gaping loophole in UK law. That is, it seems to be okay to watch live TV on a laptop or other battery operated PC, as long as it is "powered by its own internal batteries" at the time -- and not the mains.
This is a point of contention for students living away from home, as the TVL website seems to contradict itself in this regard, by saying that battery operated portable TV sets are "covered by your parents' licence". It then says that a licence is needed for laptops with TV tuners... —Preceding unsigned comment added by 126.96.36.199 (talk) 22:51, 29 January 2008 (UTC)
Limit of frequency range by country
The definition of 'country' in most cases is entirely up to the bundled control software. It usually has loads of frequency tables that often don't even match the most common cable operators in the given area. TV tuner itself can tune to any frequency, generally from 64 MHz and up, same goes for PAL and SECAM. NTSC might be a different thing, I don't know. -- J7n (talk) 14:25, 17 June 2008 (UTC)
TV tuners for Playstation 2?
The PS2 uses an output of left/right (white/red) stereo sound along with composite video (yellow). New media computers come with input jacks for these, along with combo tuners. Shouldn't this be able to convert this analog PS2 input to be able to display the games on the monitor using Windows Media Center or something? Tyciol (talk) 23:10, 10 April 2009 (UTC)
I believe the demodulation of the 8VSB, QPSK, 16QAM, or 64QAM always happens in the tuner card. The CPU may be used to DECODE the demodulated MPEG stream. — Preceding unsigned comment added by 188.8.131.52 (talk) 11:48, 30 July 2013 (UTC)
