The videofeatures supported by thesemultimediaaccelerators, including video scaling,can be used toenhance the display of the MPEG-1 video decompressedby the Scenic/MX2.The Scenic/MX2integrates into a single device thefollowing functions:· MPEG-1 30frames/second video decoding· MPEG-1 CD-qualityaudio decoding· A timer tofacilitate synchronization ofdecoded audio andvideo· A serial outputport for direct connection of alow cost stereoaudio D/A converter such asthe S3 Sonic/ADÔaudio DAC· A Scenic Highwayinterface to enable the Host(via the S3 multimediaaccelerator) to accessScenic/MX2 registersand private memory andto burst writecompressed video and audiodata to theScenic/MX2.

Theon-chip timer enables thesoftware driver tocontrol the synchronizationof audio and videoduring playback.· The multimediaaccelerator is responsible forreceiving thesequence of decompressedvideo images overthe Scenic Highway,converting the YUVimages into RGB format fordisplay on acomputer monitor, and for anyadditional videoprocessing (video scaling,dithering, videoeffects, etc.).FRAME BUFFERRGB YUVSTREAMSPROCESSORGRAPHICSACCELERATORSCENICHIGHWAYINTERFACELOCAL BUS INTERFACEANALOGRGBRAMDAC/CLOCKSCENICHIGHWAYINTERFACEMIUDVPMPEGADEMPEGVDE0.5 MBYTEDRAMSonic/ADAUDIO DACSPPCI OR VL-BUS ISACPUSYSTEMMEMORYDIGITIZERCOMPOSITEOR S-VIDEOCDROMSOUNDCARDDATACONTROL85Scenic/MX2128 PINPACKAGETrio64V+TIMERI2SSYSBLKFigure 1.
