128-BIT 3D MULTIMEDIA ACCELERATOR

RIVA128ZX

12/85

• 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
