    PROSHARE VIDEO: SUPPORTED DCI GRAPHICS CARDS DOCUMENT

    
       Video cards that support the Display Control Interface (DCI)
    
       specification can provide the ability to display larger resolution video
    
       without impacting frame rate.  This means that when the ProShare video
    
       product is used in a system with a DCI graphics card from the list
    
       below, either the local or remote video can be displayed at either 640 x
    
       480 pixels or even in full screen mode at the frame rate of the chosen
    
       video mode, sharper or smoother.  The ProShare video system software
    
       takes advantage of the graphics card's ability to smoothly scale the
    
       video.
    
    
    
       DCI Support Requirements for ProShare Video Release 2.0:
    
    
    
       * When you first install the ProShare software, DCI support is not
    
       enabled.  If you have a DCI-compatible display controller, and you want
    
       to use it with the ProShare application to view full-screen video, you
    
       must make a change to the PSSYSTEM.INI file in the ProShare software
    
       directory.
    
    
    
       Follow these instructions to make the change:
    
    
    
          1 Start the Diagnostics & Utilities application that came with your
    
          ProShare software.
    
          2 Scroll down the list of diagnostics and utilities and double-click
    
          on PSSYSTEM.INI to open the file.
    
          3 Use the Search menu to find the line that contains the text
    
          FreshCalibration.
    
          4 Edit this line so that it reads FreshCalibration=1.
    
          5 Use the Search menu to find the line that contains the text
    
          EnableDCI.
    
          6 Edit this line so that it reads EnableDCI=1.
    
          7 Save and close the file.
    
          8 Exit the Diagnostics & Utilities application.
    
          9 Restart the ProShare application.
    
    
    
       * ProShare Video V2.0 cannot do full screen if you are only running 256
    
       colors (8-bit color) under Windows 3.1x.
    
    
    
       * The Full Screen video window option is not supported under Windows 95.
    
        Windows 95 uses Direct Draw and does not support DCI.
    
    
    
       * In most cases you will need to install the Microsoft Video for Windows
    
       Runtime 1.1e.  Your video card will come with this disk.  If you need,
    
       you can download Video for Windows Runtime from Intel*s www site
    
       (www.intel.com).  Download the file IV32RT.EXE from the Intel Smart
    
       Video Recorder support section.
    
    
    
       For more detailed information about the DCI specification and how it
    
       relates to ProShare Video, you can obtain Document 8765; DCI: Moving the
    
       Industry Toward High-Quality, Full-Screen PC Video.

       The Diamond Viper Pro Video 2Mb PCI card was tested with ProShare Video
    
       version 2.0.
    
    
    
       Because this card has been discontinued, this card is not recommended
    
       for DCI full screen video conferencing with ProShare Video 2.0.
    
    
    
       * For DCI support under Windows 3.1x, Intel recommends using Viper Pro
    
       Video driver version 2.03e.
    
       * You will need to install Video for Windows Runtime to enable DCI
    
       support.
    
       * Using the 256 or 64K color driver for the Viper Pro Video card you may
    
       see a dark colored band appear at the top of the Remote video window
    
       intermittently.  This problem does not occur using the 16.7 million
    
       color driver (24-bit driver).

       The ATI Mach 64 Graphics Pro Turbo 4Mb PCI card was tested with ProShare
    
       Video version 2.0.
    
    
    
       Because of problems that occurred during testing, this card is not
    
       recommended for DCI full screen video conferencing with ProShare Video
    
       2.0.
    
    
    
       * For DCI support under Windows 3.1x, Intel recommends using ATI driver
    
       versions 1.55 or 2.11.
    
       * For DCI support, you need to install the Motion Video Accelerator
    
       (MVA) drivers.
    
       * Also for DCI support, you need to manually edit the ATIDCI.INI in the
    
       WINDOWS directory.  Add the parameter IF09 (IF-"zero"-9) after any other
    
       parameters on the Enumerate line as shown.
    
    
    
        Example: Enumerate=Device
    
    
    
        change to     Enumerate=Device, IF09
    
    
    
       * Using ATI driver v1.55, intermittent page faults and color distortion
    
       can occur while taking snapshots with ProShare Video v2.0.  Video
    
       performance is good however.
    
       * Using driver v2.01, you may see General Protection Faults in ATI's
    
       video driver (M64DCI.DLL) when DCI is enabled.
    
       * Driver v2.11 includes fixes for problems with v1.55 and v2.01, but the
    
       video frame rate sporadically becomes very slow.

       Number Nine Visual Technology, 800 438-6463 www.nine.com 
    
       The Number Nine 9FX Motion 771  4Mb PCI card was tested with ProShare
    
       Video version 2.0.
    
    
    
       Because of problems that occurred during testing, this card is not
    
       recommended for DCI full screen video conferencing with ProShare Video
    
       2.0.
    
    
    
       * Testing was done using the Motion 771 driver version 2.12.
    
       * Strange video stretching occurs under Windows 3.1x (whether DCI is
    
       enabled or not).  This problem is apparent when the green volume level
    
       indicator is displayed in the remote video window.
    
       * When in Smoother mode, DCI full screen video will not work.  Sharper
    
    
    
       mode full screen will work however.  (Smoother and Sharper mode are
    
       selectable under Preferences for video.  The default mode is smoother. 
    
       Sharper mode can be selected by checking the box for *Prefer Sharper
    
       Image over Smoother Motion*.) * Color distortion or artifacts can occur
    
       while in DCI mode when displaying saturated colors (for example:  a
    
       large solid-colored object of a bright color such as red).
    
       * When in a continuous presence multipoint conference using the normal
    
       size remote video window, the remote video window will be split unevenly
    
       so that the two lower 'sub-windows' are only partially visible.  This
    
       problem is not apparent when you enlarge the remote video window.
