HISTORY
The first commercially successful telepresence company, Teleport (which was
later changed to TeleSuite), was founded in 1993 by David Allen and Harold Williams. The
original intent was to develop a system that could allow families to interact across great distances
without the hassle or costliness of flying. The first systems (which they called TeleSuites) looked
more like something out of an upper class home rather than a conference room in an office suite
(which are what most systems are used for today).
Hilton Hotels had originally made a deal with them to begin installing them in
their hotels throughout the United States and other countries, but usage was low. The idea lost
momentum and Hilton eventually backed out. They later began to focus on business oriented
telepresence systems. Shareholders eventually held enough stock to take over the company,
which ultimately led to its collapse. David Allen purchased all of the assets of TeleSuite and then
called the new company Destiny Conferencing.
Although they survived, the idea did not truly catch on until other megacorporations
jumped onboard such as Polycom, HP, and Cisco released similar systems around
the mid 2000's. Polycom eventually bought out Destiny Conferencing and now carries the
TeleSuite telepresence system now known as the Real Presence Experience (RPX).

IMPLEMENTATION
For a user to be given a convincing telepresence experience, sophisticated technologies are
required. The Cisco TelePresence Meeting solution consists of the Cisco TelePresence
technology, codecs, cameras, lighting arrays, microphones, speakers, and endpoints that consist
of one or more 65-inch plasma screens, and in some models, one-half of a "virtual" conference
table. Also included is the Cisco TelePresence Manager, which provides event management, help
desk and consolidated device status reporting. It enables integration to enterprise groupware for
easy scheduling and launching of Cisco TelePresence calls. Integration with Cisco Unified
Communications Manager 5.1 and enterprise groupware provides Cisco TelePresence with just
one button to push to launch calls directly from the phone.
Cisco TelePresence endpoints consist of two models, designed for different numbers of
users and different size environments:
• Cisco TelePresence 3000-A virtual table with seats for 6 on each side, including three 65-inch
plasma screens, speakers, microphones, and lighting
• Cisco TelePresence 1000-Designed to be flush-mounted along a wall space for easy use in
smaller footprint areas (for example, individual offices, bank branches, lobbies, doctor's offices)
includes one 65-inch plasma screen, speakers, a microphone, and lighting.
VISION
A minimum system usually includes visual feedback. Ideally, the entire field of view
of the user is filled with a view of the remote location, and the viewpoint corresponds to the
movement and orientation of the user's head. In this way, it differs from television or cinema,
where the viewpoint is out of the control of the viewer.In order to achieve this, the user may be
provided with either a very large (or wraparound) screen, or small displays mounted directly in
front of the eyes. The latter provides a particularly convincing 3D sensation. The movements of
the user's head must be sensed, and the camera must mimic those movements accurately and in
real time. This is important to prevent unintended motion sickness.
SOUND
Sound is generally the easiest sensation to implement with high fidelity, with the
telephone dating back more than 100 years, and very high-fidelity sound equipment readily
available as consumer gear. Stereophonic sound is more convincing than monoaural sound, and
surround sound is better still.
AUDIO/VISUAL TECHNOLOGY
Cisco TelePresence incorporates the most up-to-date standards and technologies to offer the
best audio and visual results:
H.264 video codecs to offer the highest quality and lowest bit rate
Session Initiation Protocol
Native 720p and 1080p high-definition cameras
Native 720p and 1080p high-definition encoding/decoding
Low-latency architecture and low bandwidth utilization
Wideband advanced audio coding with low delay (AAC LD)
Multichannel spatial audio with echo cancellation and interference filters to eliminate
feedback from mobile devices.
Optimized environmental conditioning to provide the best audio and video and overall
user experience
