This is an announcement for an open-source tool to use the TV-Out 
capabilities of NVidia graphic cards on Linux.

The closed-source drivers by NVidia already allow TV-Out, but only
in a limited way: Only two resolutions are supported, overscan
compensation (the size of the image on the TV) cannot be adjusted,
the video overlay does not work on the TV, and there is no way to control
the flicker filters and other image processing capabilities the 
TV encoder chip offers.

This tool was written to overcome these limitations, inspired by
TV-Tool (http://www.tvtool.de/) that offers a similar functionality
for Windows.

Features include:

* Arbitray resolutions, as far as the encoder chips supports them.

* Arbitray overscan compensation, with the same restriction.

* Multiple TV encoder chip support (So far Brooktree, Conexant, Chrontel 
  and Philips chips, and other chipsets can be added easily).

* Autodetection of TV encoder chip and PCI card.

* Control display parameters like brightness, saturation, contrast, 
  flicker filter, or bandwidth.

* Graphical user interface and command line support.

* Switching X video modes.

* Centering and resizing an X window on the X virtual viewport.

* Control downto direct register access.

The project is in the alpha stage, so there may be still bugs, and
some features need more work. However, since it is open source, you
may contribute to fix bugs and add functionality.

The project is located at Sourceforge. If you are interested, have a
