VideoVision™ Data Sheet 7/92
24-Bit Interface Card with Video In and Video Out Capability for the Macintosh
Quadra and II (NuBus) Series
Radius’ VideoVision combines breakthrough hardware and software technology to
enable mass distribution of powerful multimedia communications. Consisting of a
sophisticated video interface card, an external breakout box for external video
and audio connections, and comprehensive software controls, VideoVision enables
users to integrate audio, graphics and video capabilities on the Macintosh.
VideoVision offers immediate compatibility with all applications that support
QuickTime,™ Apple’s multimedia extension to its operating system software,
allowing the capture of digital video information as QuickTime movies or
still images. In addition, VideoVision supports both S-Video and composite
video and multiple timings and resolutions, providing compatibility with a
wide range of Radius, Apple, and other third-party computer displays and video
formats.
High Quality 24-bit Video Output
VideoVision is the first low-cost integrated Macintosh desktop product that
enables high quality output directly from a Macintosh to videotape. This “print
to video” capability allows for convenient and cost-effective distribution
of a variety of presentations, from the simple slide presentation which
incorporates QuickTime movies to the sophisticated multimedia presentation. The
high quality of the video output is due to a unique filtering process which
allows flicker-free 24-bit (16.7 million color) motion video graphics to be
output from computer to videotape. Current alternative technologies for video
output show intense flickering.
Worldwide Video Standards Support
VideoVision supports worldwide video standards for both input and output as
well as the ability to convert from one format to another. NTSC, PAL, and
SECAM video standards are supported for video input and NTSC and PAL for
video output. Both NTSC 3.58, used in the U.S., and NTSC 4.43, used in Japan,
are supported. With video input, VideoVision automatically recognizes which
standard to use and converts the data accordingly.
Real Time Video Window Resizing
VideoVision allows real-time resizing of a video window to any size the viewer
desires, without significant loss of resolution. Several products now on the
market allow video (TV, VCR, laserdisc) information to be input to the
computer and viewed in a window on the computer display. However, many of
these products either do not allow the window to be resized, or if they do,
they lose significant resolution as the window is reduced.
H-Bus Architecture
For More Power and Future Expansion
Video manipulation requires the transmission of large amounts of information
between various processor cards. VideoVision's H-Bus architecture allows
transmission of data at transfer rates of 60 Mbytes/second, overcoming the
bandwidth limitations of the NuBus architecture. Information between boards
can be transmitted much more quickly over the H-Bus. In addition, VideoVision
will support adjoining NuBus communications and add-ons such as additional
hardware compression/decompression, special effects, titling, chromakey, or
other special purpose boards.
Features Benefits
Output to videotape Enables Macintosh users to produce high quality
videotape capable of running on any standard
VCR; eliminates the cost of using expensive
high-end professional video equipment to
“print” Macintosh-based graphics, text, sound
and video
24-bit convolution Allow users to export photorealistic still and
motion images for presentations, animation, etc., to
tape, resulting in true color, flicker-free output
100% QuickTime Generates files that are fully with hundreds of
compatible QuickTime applications
On-board international Provides for incredibly easy access to video
standards conversion produced from around the world as well easy
conversion from one format to another for video
in and video out
Variable window resizing Lets users customize video windows for
presentations, educational tapes, informational
kiosks, etc., without sacrificing quality
H-Bus architecture Allows for increased data transmission rates and
supports possible future add-ons such as
compression/decompression, special effects,
titling, and chromakey
Compatible with a wide Provides flexibility in display
range of displays configuration; users can choose Radius, Apple, or
other third-party computer displays
Expansion slot Supports possible add-ons such as an external
tuner module and external device control
Single card solution Conserves valuable slots by combining
24-bit color interface with video in/out
capabilities
System Requirements
VideoVision consists of a video interface card, an external breakout box for
external video and audio connections, and comprehensive software controls. It
requires an Apple Macintosh Quadra or II (NuBus) Series computer running 6.0.7
or System 7 and Radius, Apple, or other third-party display.
