3.6
The RIVA128ZX Multimedia Accelerator provides
connectivity forvideo input devices such as Philips
SAA7111A, ITT 3225 and Samsung KS0127
through an ITU-R-656 video input bus to DVD and
MPEG2 decoders through bidirectional media port
functionality.
Supported through VPE extensions to Direct-
Draw
Supports filtered down-scaling and decimation
Supports real time video capture via Bus Mas-
tering DMA
Serial interface for decoder control
VIDEO PORT
3.7
DIRECT RGB OUTPUT TO LOW COST
PAL/NTSC ENCODER
The RIVA128ZX has also been designed to inter-
face 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.
3.8
SUPPORT FOR STANDARDS
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 RIVA128ZX has an in-
dustry standard 32-bitVGA core and BIOS sup-
port. In PCI configuration space the VGA can
be enabled and disabled independently of the
GUI.
Glue-less Accelerated Graphics Port (AGP 1.0)
or PCI 2.1 bus interface
ITU/CCIR-656 compatible video port
