4. History of Teleconferencing
 It all started about 54 years ago in the 1960’s as a
vision from American Telephone and Telegraph (AT
& T) through its Picture phone device – the birth of
teleconferencing.
 At that time, travel was cheap and many people
simply didn’t understand that the Picture phone would
be a workplace changing technology.
 It took 54 years and hundreds of millions of dollars
spent on fuel consumption for the idea that grew out
of Picture phone to become a real- world every
day application embraced by millions worldwide.

6. Audio Teleconference /conference calling
• Audio Teleconference (Voice-only):
Interactively links people in remote locations
via telephone lines. Audio bridges tie all lines
together. Meetings can be conducted via audio
conference. Preplanning is necessary which
includes naming a chair, setting an agenda, and
providing printed materials to participants
ahead of time so that they can be reviewed.

7. Video Teleconference
• Video Teleconference Combines audio and video to provide voice
communications and video images.
 Can be one-way video/two-way audio, or
 two-way video/two-way audio.
• It can display anything that can be captured by a TV camera.
• The advantage is the capability to display moving images.
• In two-way audio/video systems, a common application is to show
people which creates a social presence that resembles face-to-
face meetings and classes and enables participants to see the
facial expressions and physical demeanor of participants at
remote sites.
• Graphics are used to enhance understanding.

8. Web/ Computer Teleconference
• Web conferencing involves various levels of audio-video and
graphics communication from computer to computer. It can be as
simple as instant messaging or more complex as evidenced by
online courses or online Web meetings.
• It’s an emerging area for distance education. Some institutions offer
credit programs completely by computer. Students receive texts and
workbooks via mail. Through common files assigned to a class which
each student can access, teachers upload syllabi, lectures, grades
and remarks.
• Students download these files, compose their assignment and
remarks off-line, then upload them to the common files.

9. ADVANTAGES
• Move Information - Not People Electronic
delivery is more efficient than physically
moving people to a site, whether it is a
faculty member or administrator.
• Save Time: Content presented by one or
many sources is received in many places
simultaneously and instantly.
• Travel is reduced resulting in more
productive time.

10. ADVANTAGES
• Language Development: Communication is
improved and meetings are more efficient. It
adds a competitive edge that face-to-face
meetings do not.
• Lower costs: Costs (travel, meals, lodging)
are reduced by keeping employees in the
office, speeding up product development
cycles, improving performance through
frequent meetings with timely information.

ADVANTAGES

12. DISADVANTAGES
• ➨ i) Hard to Officiate: In a normal meeting, one person
is usually assigned to act as parliamentarian over the
proceeding. The parliamentarian is a neutral person
who prevents the discussion from veering off-topic,
mediates arguments and keeps the meeting short.
However, when you're having a meeting over the phone,
people are less likely to respect and acknowledge the
parliamentarian. As a result, a teleconference can be
difficult to manage and officiate.
• ➨ ii) Difficult to Create Group Rapport Teleconferencing is
an impersonal means of communicating. It's very
difficult to create a group rapport, which is essential
to the outcome of the meeting.

Dr. C. BEULAH JAYARANI

13. DISADVANTAGES
• ➨iii) Lack of concern: Face-to-face meetings often
create an informal atmosphere, allowing the participants
to relax and develop a comfort level with each other.
Due to the level of formality and inapproachability it
imbues in its users, teleconferencing is specifically not
suitable for negotiation, job interviews, contract
reviews or bargaining efforts which rely on
interpersonal communication, and is thereby limited in
its viability. Many people consider it important to maintain
eye contact, observe other's gestures and shake
hands to establish rapport.

14. DISADVANTAGES
• ➨ iv) Technical Issues: In a teleconferencing
situation, equipment might break down, bringing the
operation to a halt. This can lead to delay and can be
detrimental to a business, especially if the meeting
is urgent. While video conferencing does enhance
many presentations with charts, models and
graphs, if technical problems occur, like poor
sound quality, unclear video or interrupted
connections, its usage may do more harm than
good. Moreover, participants might not be
comfortable handling the equipment.

Dr. C. BEULAH JAYARANI

15. DISADVANTAGES
• ➨ iv) Expensive for Small Companies: The
equipment cost and dial-up plans are often
considered expensive by some companies.
It is not suitable for small companies
who have a group of workers and clients
situated nearby. Unnecessary Meetings
Since teleconferences are touted as saving
people time and expenditure, meetings
might be held more often than
necessary.
