This wiki is designed to serve as a community focus and the resource of reference for users and developers of the Video4Linux framework. In the short term, the task is to document the operation and quirks of hardware supported by v4l applications, to complement and offload the [https://listman.redhat.com/mailman/listinfo/video4linux-list v4l mailing list] -- cf. [http://marc.theaimsgroup.com/?l=linux-video searchable archives].

We are also encouraging developers to turn this site into a repository of knowledge about v4l, helping to ensure that expertise acquired through much hard labor and long dedication won't get lost, but can be passed on to new developers and keep free software thriving.
'''A Few Notes Before you Begin'''


Before you jump in and make your contribution, please first familiarize yourself with the layout of the site. Doing so will help you to place your information in the right location. As the wiki grows, it takes an increasing amount of effort and discipline to keep it from quickly turning into a tangled mess. So it's up to each of us to make sure the information submitted is easy for everybody to find and access.
If you are a user looking for help, please try searching the [http://marc.theaimsgroup.com/?l=linux-video mailing list archives] first, before asking a question on the [https://listman.redhat.com/mailman/listinfo/video4linux-list v4l mailing list]. You may also be able to get immediate help on the #v4l irc channel on irc.freenode.net -- hopefully someone there will be able to help you! Don't leave your question on the wiki -- ask on the mailing list!


If you make a contibution and later find that your submission has been edited or moved to another area of the wiki, please don't
The wiki will only be as useful as we make it. Every user of video4linux has something to contribute, and we encourage you to begin right away. Whatever you can contribute will be warmly appreciated, whether it is a set of instructions for how to get a certain card working, a report on the audio and video quality of a working card, suggestions for how to extend an existing driver or write a new one, or an explanation of the internal logic of v4l itself.

'''To make a contribution, please begin by familiarizing yourself with the layout of the site, so that your contribution will end up in the right location. As the site grows, it takes increasing discipline to keep it from turning into a tangle.

This Wiki is intended to become the ultimate resource regarding all questions about Video, TV and DVB support on Linux, free DVB software and cool projects.


Like every other Wiki it relies on the contributions of its users. Also this Wiki can only get as good as you and we mean: YOU!!! make it.

Whatever you can contribute will be highly appreciated, no matter if it's a HOWTO, help and explanations how to write a driver, how to install some a driver or whether you can explain how that beast called DVB is working.

the terms "tuner" and "receiver" are often used interchangeably ... but its more appropriate to call it a receiver, with the tuner being part of the receiver

have fun, enjoy -- ''The LinuxTV WikiTeam''
In electronics, tuning refers to a process in which, first, a specific [[RF]] signal is acquired and, second, is subsequently acted upon such that any underlying content (information/data) may be extracted.


One may "tune" to a specific frequency and find that there is no underlining content to be found -- in the context of radio or TV signal reception, this would be characteristic of static or white noise.
