RIVA128ZX
128-BIT 3D MULTIMEDIA ACCELERATOR
• Support for scaled field interframing for reduced
motion artifacts and reduced storage
• Per-pixel color keying
• Multiple video windows with hardware color
space conversion and filtering
• Planar YUV12 (4:2:0) to/from packed (4:2:2)
conversion for software MPEG acceleration
and H.261 video conferencing applications
• Accelerated playback of industry standard co-
decs including MPEG-1/2, Indeo, Cinepak
3.6 VIDEO PORT
The RIVA128ZX Multimedia Accelerator provides
connectivity for video 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
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-bit VGA 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
• VESA DDC2B+, DPMS, VBE 2.0 supported
