    This is part of the abstract. Lists tools.

    Drivers are software programs that directly control the hardware, and
    provide a simpler software interface that other software (application
    programs) can use to run the hardware. There are several levels of tools
    and software that support DVI. The most fundamental level is that of the drivers. The IBM Action Media II hardware comes with drivers for OS/2
    2.0 and for Windows3.1. These drivers have two levels of interface: AVK
    (Audio Visual Kernel) and MCI (Media Control Interface a standard
    multimedia hardware control language defined for Windows and OS/2). The
    AVK level gives a program complete control over hardware, including the
    ability to set contrast, tint and brightness, and to control the volume
    of the left and right audio channels independently, etc. However, one
    must program in the C or Assembly languages to access the AVK. The MCI
    level is more accessible, although the function it provides is more limited.

    Many of the authoring tools that allow you to create programs or
    presentations using DVI provide access to MCI, including Multimedia
    ToolBook, Icon Author, MEDIAScript for OS/2(Network Technology
    Corporation), Microsoft Visual Basic, etc. As of December 1992, it
    appears that Windows access to DVI should be through Microsoft Video and Microsoft VideoTools.

    [Please note that the MCI interface in Windows does not provide capture capability. If you need to capture stills, audio and video under
    Windows, you will need to purchase capturetools from other third party developers such as Digital Media International of Sunbury, Pennsylvania.]

    If you are in the DOS environment you will find that the tools that
    support DVI include the DVI driver they need. Examples of such tools are
    IBM's Linkway Live! and MEDIAScript for DOS.
    Some tools have DVI functionality built right in. With these tools it is
    not necessary towrite your own MCI commands to the DVI hardware.
    Examples of these include Podium for OS/2 (University of Delaware),
    MEDIAScript for OS/2, and Multimedia Desktop (Datalus Incorporated of
    Okemos, Michigan).

    There are some editing tools that allow you to cut and paste clips of
    DVI motion video,such as Splice (Digital Media International of Sunbury, Pennsylvania) and Jasmine Clipper DVIEditor (Jasmine Multimedia
    Publishing of Los Angeles, California). Several companies are working on
    a collection of DVI capture, playback and editing tools (scheduled to
    become avail-able in early 1993). Jasmine Multimecia Publishing also has
    the Jasmine Six Pack, a collection of six CD-ROMs featuring clip art
    video and music that can be incorporated royalty-free into any DVI
    application. The Jasmine CD-ROMs are also available individually.
    There are two very specialized tools that use the ActionMedia II card to capture, assemble and edit high quality video for broadcast purposes.
    These are D/Vision (TouchVision Systems, Inc. of Chicago, Illinois) and
    Montage (Montage Group, Ltd. of New York City).
