Description
-----------
This driver provides some access to the Brooktree bt869 found on some video
cards (like the 'Voodoo3 3000'). Typically, the output can be either an
s-video connection or composite video. Resolutions supported using the
chip's built in configurations are 640x480 or 800x600. Other possible
implementations may allow for double resolutions with some decimations
(e.g., a monitor running at 1280x960 but the TV out getting every other
pixel for 640x480).
This driver provides some access to the Brooktree bt869 found on some

either an s-video connection or composite video. Resolutions
supported using the chip's built in configurations are 640x480 or
800x600. In addition, a 720x576 PAL mode and a 720x480 NTSC mode,
both without overscan compensation, are supported - a convenient
configuration for video playback.
Other possible implementations may allow for double resolutions with some
decimations (e.g., a monitor running at 1280x960 but the TV out getting every

Driver Features
---------------
Stanards: (US) NTSC or PAL (PAL untested)
Resultions: 640x480 and 800x600
Depths: 16 bit or 32 (I forgot if 24 bit worked OK, it probably does)
Standards: (US) NTSC or PAL
Resolutions: 640x480, 800x600, 720x576 (PAL only), 720x480 (NTSC only)
Depths: 16, 24 or 32 bits
Colorbars: Switch on the built-in color bar generator. (FYI- using a blue
filter, you should see only alternating bright stripes of equal brightness.
Adjust your TV's color and saturation if this isn't the case.)
SVideo: composite or s-video output. Also, theoretically, RGB output, though
this isn't tested and will require that your card presents all three DAC outputs
(the 3dfx Voodoo3 doesn't)
In your XF86Config file, you should have these entries for NTSC output:
ModeLine "640x480NTSC" 28.195793 640 656 658 784 480 520 525 600
