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 welcome section is way toooooo wordy. it needs to be cut down to be short and sweet'''''


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.


==[[Image:Software_viewing_apps_icon.png|50px]] TV Related Software SubPage:==
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.


It would seem that, instead of re-inventing the wheel, the existing [[TV Related Software]] page is an ideal candidate to be reworked as the TV Software SubPage

distinguish between tuner/tuning/to tune/receiver ...
in contemporary dialogue/common language:
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


[[tuning]]
We want to aggregate information about available hardware, v4l experiences, HOWTOs, and technical information about the workings of v4l devices work, hardware quirks, software applications
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.
''The basic plan is to collect facts about available hardware, v4l or dvb experiences, HOWTOs, encyclopedia-like information and explanations about how v4l and dvb work, what an [[EPG]] is and so on,
Save and share knowledge.'' '''

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.
