1945.0. "Urgent:output monitor graphics onto video/TV ?" by ZPOVC::POHING () Tue Apr 29 1997 04:39

    Hi,
    
    I have a customer who needs to capture a graphics display on the
    monitor display & store onto a video tape (eg VHS). To be view on TV.
    
    Could we do it on the alphastation with additional hardware/software ?
    
    The 2nd question is , can we output the graphics display onto the TV
    screen?
    
    Thnxs.
    
    
    Rgds,
    Poh Ing

	Which AlphaStation? Which OS? The DPS Perception card can be used under NT to spew digital frames to VHS, etc.

	The most direct way to do this is with a device called a scan converter which converts high frequency RGB monitor signals to composite video which can be displayed on a TV or taped on a VCR. These devices run all the way from cheap ($200) units with minimal filtering that will only support relatively resolutions to units costing $10,000 or more which will support any scan rate and provide high quality filtering. The DPS Perception isn't a good fit for this application. Digital's AV301/AV321 could be used, but you'd get better results with less work using an external scan converter. Tom

	Use a scan converter. I can't say it any more clearly than that.
