Radeon TV-Out

In 2007 Alex Deucher added preliminary TV-Out-support based on the gatos-code to the randr12-branch of the ati-driver. The branch has now been merged to the git HEAD.

Driver Releases

Starting from the 6.7.191 pre-release the X.org ati driver supports TV-Out on selected cards. That means stable version 6.8.0 and newer have the support. A new enough driver is also included starting in eg. Fedora 8 and Ubuntu 7.10.

How to build

See RadeonTVbuildHowto.

How to use

TV-out may be enabled by using a recent driver and xrandr utility:

  1. xrandr --addmode S-video 800x600
  2. xrandr --output S-video --mode 800x600
  3. xrandr --output S-video --set tv_standard ntsc

History

How we got here from the GATOS Patch

There was a very old effort by the gatos-project to support TV Out on ATI Radeons. It was GPL-licensed in the past, but in 2007 all authors agreed with relicensing under MIT-license, so that it was brought to a xf86-video-ati's branch and later on merged to the main driver.

Original gatos code

Relicensing

Frederico Ulivi (original author) agreed to relicense the code under a MIT-license (which allows inclusion in the xorg-driver)

All others agreed to the relicensing

atitvout

On some older cards the tv out can be enabled with atitvout, which is not developed anymore:
