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.

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.

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:
