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, 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
* Reduce fragmentation -- common problem
* USB example of insanity


* User Accounts / Logons
* Exporting History and discussions -- preserve


==Wiki Main Page:==
* more inviting (web and wiki)
[[Image:Graphic_banner_rough_idea_test3.png]]
* branding (common)
* unified look and feel
* new features - like sortable tables, news (web, for kernel updates, discussions)

This wiki is intended to serve as a community focus and reference source for the projects covered under the LinuxTV umbrella/framework. It is hoped that this Wiki will, in time, become an authoritative source of information and support regarding the use of [[analog TV|analog]] video and [[digital TV]] sources on Linux.

Whether that goal is achieved depends very much upon fellow users and developers such as yourself. Like all other wikis, the LinuxTV wiki relies upon the contributions of its users, and therefore will only be as useful as we make it. As every user of LinuxTV is bound to know something useful in relation to the project's coverage, we encourage you to help with the task of turning this site into a repository of knowledge.


Now enjoy and have fun! -- The LinuxTV WikiTeam [People behind V4L]
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 -- whatever knowledge you can provide will be highly appreciated. Help ensure that your expertise acquired through dedication and hard work doesn't get lost in the ether, but can instead be passed on to new developers and users alike, and can help to keep free software thriving.

[[tuning]]
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.
