Interop Show Demonstration Highlights Versatility of InVision Windows Video
Conferencing Technology

Network Hardware, Software, and LAN/WAN Providers to Jointly Demonstrate
New Windows Video Conferencing Technology Using Interop Show Network

SAN FRANCISCO -- At this years Interop 93 August exhibition, InVision
Systems Corporation (formerly InterVision Systems) will be demonstrating
InVision(tm), Video Conferencing for Windows, at various sites around the
show floor using the show network. 

Companies expected to participate in the demonstration include Beame &
Whiteside, Ltd., LANNET Data Communications, Inc., Optical Data Systems
(ODS), Kalpana Inc., ALANTEC, Network Express, Inc., MFS Datanet, Inc.,
and Performance Systems International (PSI). The demonstration is designed
to show that InVision's audio and video conferencing technology has the
versatility to support virtually any standards-based networking
infrastructure.

InVision, Video Conferencing for Windows, consists of a CODEC
(compression/decompression) interface card, a miniature color video
camera, a telephone handset module, and software to add video
teleconferencing capabilities to any PC workstation. Using Microsoft
Windows 3.1 as the interface, InVision supports full-motion,
bi-directional audio-video packets across any conventional computer
network architecture, including Ethernet, Token Ring, FDDI and ISDN. And
InVision can take full advantage of Windows's scalable images and
multitasking so users can access files and data while conducting a
teleconference.

"InVision is the first company to get it," said Paul Callahan, senior
analyst for Forrester Research of Cambridge, Mass. "At the desktop, video
conferencing has to rely on PC LAN technology as the distribution
mechanism. It's not any easy problem to solve, but that's the reality."

"What InVision offers is a low-cost video conferencing solution that takes
advantage of the existing LAN architecture," said Jim Geddes, president of
InVision. "In all the demonstrations at this year's Interop show, the
interconnecting infrastructures may vary, but the two most important
elements remain the same: PC workstations running off-the-shelf TCP/IP.
These common denominators make video conferencing a cost-effective
technology that is accessible to everyone, regardless of their network or
their budget."

Standards-based Technology

A demonstration of InVision's compatibility with off-the-shelf TCP/IP
implementations for the PC will be incorporated into Beame & Whiteside
Software Ltd. demonstrations running in Booth 1814. Demonstrations will
include InVision running over BW-TCP and BW-NFS, Beame & Whiteside's
TCP/IP and NFS client software for Windows. While InVision will be
conducting a Windows-based video teleconference across the show network,
Beame & Whiteside will be using the same workstations to highlight new
features in the latest release of its TCP/IP and NFS software, such as a
new electronic mail handler that supports UNIX mail from Windows, support
for Windows Sockets API v1.1, new SL/IP functions for serial link network
access, and new CD-ROM drive support. Since InVision uses TCP/IP as the
transport protocol, Windows workstation users can simultaneously transfer
data using the File Transfer Protocol, access other TCP/IP and NFS file
servers, send electronic mail using the Simple Mail Transfer Protocol, and
access other TCP/IP and NFS services at the same time they are using
InVision's teleconferencing capabilities.

Infrastructure Independent

Other Interop demonstrations are designed to show that InVision is
compatible with any wiring infrastructure, including the new
high-bandwidth switching hub systems. For example, LANNET Data
Communications Inc. will be demonstrating InVision with its newly
introduced LANswitch intelligent hub system in Interop Booth 1310.
LANswitch provides dynamically allocated bandwidth for virtually unlimited
number of video conferencing sessions with a 1.28-Gbps, ATM-ready,
cell-switching backplane and dynamic switching 10BaseTV Ethernet modules.
LANswitch's ASIC-based 10BaseTV modules utilize adaptation layers and
congestion control techniques to prioritize audio and full-motion video
data transmissions so that no packets are dropped and video is delivered
smoothly to the desktop over standard Ethernet. LANswitch is an ideal
technology to support a product such as InVision.

In Booth 1834, InVision will be demonstrated running over ODS's Infinity
Switchable Hub system, a chassis-based connectivity solution with modular
backplanes to support FDDI, Ethernet and Token-Ring, and even the new
Asynchronous Transfer Mode (ATM) technology. ODS's Infinity Hub is
designed to support scalable, easy-to-create network and workgroup
configurations that can be integrated into a single network. These
high-bandwidth network devices will show how easy it is to set up an
InVision teleconference over Ethernet, FDDI, or Token-Ring architectures.
ALANTEC will also be demonstrating InVision in Booth 5952 in conjunction
with its PowerHub intelligent switching hub, which incorporates a new
technology, IP Multicast routing which was specifically developed to
support multimedia applications such as multi-participant desktop video
conferencing. The IP Multicast routing capability in the PowerHub makes it
possible to set up point-to-multipoint data transmissions without
degrading network performance by broadcasting data packets to every device
on the network. One user sends traffic to the PowerHub, which in turn
forwards the traffic to selected groups of users for interactive desktop
applications, such as video teleconferencing. By combining InVision with
IP Multicast routing, it's possible to connect multiple users in a single
video teleconference.

InVision is also ideally suited to interoperate with technology such as
Kalpana's EtherSwitch, which is being shown in Booth 5344. EtherSwitch is
a high-performance Ethernet switch that creates a parallel LAN
architecture to increase data throughput up to 600 percent. Unlike
conventional store-and-forward router systems, the EtherSwitch sets up
parallel data paths that filter and forward all network traffic without
losing packets. Since InVision's audio and video information are sent as
conventional network packet traffic, systems such as the EtherSwitch will
make it easier to set up video teleconferences without worrying about any
potential impact on network bandwidth or data throughput. Kalpana's newly
announced, full-duplex Ethernet is also ideally suited for applications
such as video teleconferencing.

Wide Area Teleconferencing

InVision is also compatible with wide area networking systems. In Booth
325, for example, Network Express will be demonstrating InVision using its
ISDN routing system. A PC workstation running TCP/IP and equipped with
InVision video conferencing system will be connected to an NE ISDN router,
which then routes packets from LAN to LAN to set up an InVision
teleconference with a remote PC workstation. A single NE ISDN Router can
support up to eight simultaneous video teleconference sessions (at 256
Kbps each), or can provide higher quality point-to-point connections using
a wider bandwidth.

In Booth 5304, MFS Datanet will be demonstrating InVision with its national
ATM network which currently links fourteen cities. ATM technology is
hundreds of times faster than conventional communications systems since it
uses a small, fixed cell size for data and high-throughput switching
systems to achieve higher bandwidth connectivity. MFS executives predict
that ATM infrastructures such as MFS Datanet will be ideal for graphics
applications such as video teleconferencing because the infrastructure can
support a greater bandwidth and faster data throughput which makes it
easier to support real-time video and audio.

In Booth 5776, PSI will be demonstrating InVision running over its
InterFrame Service, which delivers dedicated access to the Internet at 56,
128, 256, 384 and 512Kbps, and using T1. Among other applications,
InterFrame can support Internet packet video technology. PSI's InterFrame
is supported by a new multi-tier backbone that integrates cell-based
switching, Frame Relay link-level access, and state-of-the-art router
technology. Using InterFrame as a network infrastructure, InVision can be
used to set up Windows-based teleconference sessions between any two users
on the Internet.

"Interop is the ideal forum to showcase the power and compatibility of
InVision," said Geddes. "Interop has traditionally been used to showcase
how new standards-based technologies work together, and it gives us an
opportunity to show that there are still new applications for established
standards such as TCP/IP protocols. It also lets us demonstrate how
different local and wide area network technologies can readily support
PC-based teleconferencing. Attendees know that if new technology will run
on the Interop show network, it will certainly work on their own
networks."

InVision is compatible with all off-the-shelf network adapters and a wide
variety of network drivers. As part of its interface, InVision offers an
on-screen "mute" button and adjustable volume, contrast, brightness, and
tint controls. It also has a Video Capture function to capture single
image frames and multiple frames to disk. InVision is also compatible with
any TCP/IP networking system for the PC, and has been thoroughly tested
with TCP/IP solutions from Beame & Whiteside, NetManage, Microsoft, The
Wollongong Group, FTP Software, Frontier Software, and other vendors. It
has an adjustable transmission rate so information can be sent at 256,
384, or 512 Kbps, to optimize the network load. InVision can also generate
from 10-22 frames-per-second. TheInVision Performance System Kit is
available with Intel's more powerful CODEC, the Action-Media 2, which was
jointly developed by IBM and Intel, and is priced at $3,395. The product
first began shipping to customers in June.
