The
Wonders of Video Conferencing
Video Conferencing is the ability of parties
around the world to communicate visually and verbally using
a two-way electronic system to conceptualize, design, deliver
quality and administrator reliability for a productive corporate
experience.
The technology surrounding video conferencing integrates both
audio and video data and converting the concentrated signals
into a real time interactive technology. This telecommunication
system of audio and video transmission is also called video
teleconference, which was first seen on the early years of
1968.
The history on the wonders of Video Conferencing can be traced
back to the roots of early analog communication period. After
the birth of television, there was an attempt to draw a communication
using the image and audio transmitting box by converting it
into a two closed circuit television with cable communication.
It was National Aeronautics and Space Administration (NASA)
who first foster the first video conferencing technology during
their space flight by using the UHF radio frequency then linking
it to satellite to establish communication to far-away locations.
However, such integrated and advance communication is relatively
expensive by nature, thus can’t be used for meetings conducted
by the general public whether for business or personal uses.
The ineffectivity of the technology to other industries can
also be traced by the poor receptions of audio and video systems.
The lack of efficient compression techniques can be traced
by dreadful
Video captures which produces dreadful picture quality and
audio. It was only in 1980’s that this technologically advanced
communication became possible through the birth of ISDN. ISDN
paved way for the minimum bandwidth of 128 kilobits per seconds,
which compresses audio and video transmissions. Using ISDN,
images where digitally replicate allowing a 2 way TV with real
time audio and video vision. With the birth of ISDN, dedicated
systems of video conferencing started to expand.
On its expansion on 1990, the relatively expensive technology,
which revolves in exceedingly costly equipment, software and
network requirements has been transformed into a standardized
technology, which is accessible by the public at a practical
cost. IP source video conferencing started which allowed a
more reliable video compression technology allowing PC and
desktop video conferencing. Also, video conferencing software
liked MSN Messenger and Yahoo
Messenger existed thus catering for an affordable and
notwithstanding technology.
The main technology used in a video conferencing was digital
compression of audio and video streams in real time system.
Video conferencing works with a use of video camera that generates
video signals. The so called video features numerous number
of individual picture frames which were made up of two fields.
This fields were separated during video transmission and then
joined on the latter part of the reception period. Moreover
the procedure involves maximizing network cost and reception
quality. Thus, audio and video must be compressed through video
code or coder decoder system. With the video code procedure,
video and audio motion are more fluid and well receive by the
other framed side party which then passed to a communication
networks like ISDN. The audio features of video conferencing
operates a way where all communicating parties can speak and
see each other at the same time.
The wonders surrounding the technology of Video conferencing
can be classified into two types first is the point to point
and the second is multipoint. Relatively, Point to
point is
the simplest video conferencing method which only involves
two IP addresses that of the two users, generally to establish
and directly connect for the point of their conversation. Generally,
point to point is used by home users or single transmission
communication as largely communication depends on two personal
computers or PC’s. On the other hand, multipoint video conferencing
uses a multipoint bridge, which caters to connect three or
more users using a server or a single central hub device using
a room system for a large conference settings.
Relatively before, the innovative technology of Videoconferencing
can only be taken advantage by large companies who have the
buying power to invest in this new genre of communication.
As years and technology progresses, there has been a spectacular
decrease not just in the price of the equipment but more on
the procedure taken by users. It is remarkably without doubt
that many organizations resorts on video conferencing as a
way of communicating with their business partners world-wide
or by executing their corporate functions such as sales presentations,
trainings, resourceful estimation or hiring consultations.
Notwithstanding, the cost of video captures and display technology,
businesses and generally the public use personal videoconference
systems based on web cameras, software compressions and free
software particularly chat. Moreover, regardless of the type
of Video conference used, most system allow the exhibit of
papers using electronic document camera, playing a pre-recorded
video or exhibiting presentation using different Microsoft
software.
Lastly, aside from video being shared and transmitted, Video
conferencing allows sharing of PC applications, which initiates
a remarkably meeting environment beyond physical distance. # # # # #
