This is my sandbox. Being a sandbox, everything you see here is a work in progress. However, my intention should be pretty clear from the content.
This is my sandbox. Being a sandbox, everything you see here is a work in progress.


==But if my intention isn't clear, here's what I propose:==
* Unification
* avoid duplication of effort (inter-duplication), more efficient
* One stop shop
* More user friendly, spawn more interest
* more info (beyond supported -- spawns interest in new projects?)
* Co-ordination - / oversight ... reaching critical mass
* Formalize entries .... slightly pedantic, but necessary (think library -- they don't just throw things on shelves)
* Reduce subject fragmentation -- common problem
* Reduce duplication (intra-duplication) -- common problem --> USB example of insanity
<BR>
* User Accounts / Logons
* Exporting History and discussions -- preserve
<BR>
* more inviting (web and wiki)
* branding (common)
* unified look and feel (wikitable)
* new features - like sortable tables, news (web, for kernel updates, discussions)

This wiki is intended to become an authoritative source of information regarding the use of analog video and digital TV sources under Linux -- i.e. the subject matters covered under the LinuxTV umbrella/framework. The basic plan is to aggregate information about: available hardware; how v4l or dvb work; software used with the hardware and so forth.

Like all other wikis, the LinuxTV wiki relies upon the contributions of its users. Hence, it will only be as useful as we make it! So we encourage you to share your knowledge and help with the task of turning this site into a repository of knowledge. Your input (whether it be by providing a set of instructions for how to get a certain device working; a minor improvement to an existing article; or an explanation for some complex concept) will be highly appreciated.

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 make a contibution and later find that your submission has been edited or moved to another area of the wiki, please don't feel offended. Everyone understands and appreciates the time and efforts you took, but bear in mind that a factual and well-organized resource for everyone interested in analog or digital TV is the ultimate aim of the LinuxTV wiki.

Submitters should also know that, to keep the information contained in the wiki free, all contributions are automatically licensed under the GNU General Public License GPL. If you wish, you may specify in each case that your contribution is dual-licensed under the MIT License. Please do not reproduce or submit copyrighted works without obtaining the express consent of the owner or its agent.

Lastly, to help keep the wiki free from spam, contributors are required to set up an account and to sign in before they can post to the wiki. (This is a painless process that only takes a few seconds). To sign up an

Just toying

Would like to try to setup a table for the chipsets using templates such that, with using logic to define relevant fields, we have all the data contained in one spot (I guess much like Henrik was doing with the DVB-T USB stuff), but can then parse the info for display in relevant articles, such that there isn't duplication. Present duplication example:
