The RIVA 128 has also been designed to interface
to a standard PAL or NTSC television via a low
cost TV encoder chip. In PAL or NTSC display
modes the interlaced output is internally flicker-fil-
tered and CCIR/EIA compliant timing reference
signals are generated.

Multimedia support for MS-DOS, Windows
3.11, Windows 95, and Windows NT
Acceleration for Windows 95 Direct APIs in-
cluding Direct3D, DirectDraw and DirectVideo
VGA and SVGA: The RIVA 128 has an industry
standard 32-bit VGA core and BIOS support. In
PCI configuration space the VGA can be en-
abled and disabled independently of the GUI.
