Another interesting application is when participants can not
only view updates to spreadsheets simultaneously, but also input changes in real
time. Apart from this it has also become effective for sales and marketing
activities, and is quite reliable as a training tool as well. Other applications
include providing information to shareholders, or to end-users through help
desks.
Cost-effective Connection
From a cost perspective, Web marketing is a much more effective way to go.
The challenge for companies is to make the presentations sufficiently warm and
interactive to create a near touch-and-feel effect. The use of two-way video,
instant messaging, and Web-based conferencing effectively counter that
challenge.

Drivers |

VC MCU:
There have been several
advancements in the videoconferencing technology. Today, it has moved up
from point-to-point communication to multiple locations involving several
groups of people. The equipment that allows such a phenomenon is termed as
an MCU (multi-point control unit). An MCU is a central multimedia server
to which videoconferencing terminals are connected. The MCU manages the
audio and video for each participant, providing a virtual meeting room for
the group. For larger conferences, several MCUs can be serially added to
increase capacity and perform load balancing.
HD MCU:
When applications need high
definition telepresence such as telemedicine, distance learning, and
corporate training, some of the latest MCUs incorporate high definition
(HD) continuous presence conferencing, allowing users to enjoy a crystal
clear and full motion video format. With more than 10x the performance of
standard definition (SD) MCUs, these HD units deliver conferencing without
limitations or restrictions.
Webconferencing: In-built
streaming servers that allow streaming of video, audio, and presentations
to any Web browser have become the standard in current applications.
IP Video Conference Recorder
and Streaming Server: The
IPVCR allows you to record video, audio, and computer presentations from
standard videoconferencing equipment. The content can be streamed live or
played back on demand at multiple speeds to a PC or any videoconferencing
endpoint.
IP Networks: With
IP becoming an all-encompassing technology, its not surprising that the
videoconferencing solutions too are transitioning to packet-switched IP
networks from the traditional circuit-switched ISDN transmission. The
various benefits include lower running costs, easier management and
control, and remote monitoring.
Video Compression:
New video compression formats
such as H.264 provide up to 50% improvement in quality, thus enabling TV
quality video on inexpensive IP or ISDN networks.
Data Collaboration: The
H.239 standard is now universally adopted by all major videoconferencing
manufacturers for data sharing, and making it simple for users to see the
presenter(s) and the presentation (data) simultaneously. Now, a
collaboration session via an H.239 video conference wherein distributed
teams share PC-based documents, while also enjoying audio-visual
communications, has the effect of a virtual conference room or classroom.
Real time inputs and changes can be made on excel sheets or powerpoint
presentations.
Wideband Audio: Wideband
audio technology used in videoconferencing applications provides superior
sound quality compared to standard telephone networks. AAC (the same
algorithm used in MP3 players) is now used in videoconferencing systems
resulting in superior speaker intelligibility, thereby reducing what is
termed as meeting fatigue. |
There have been marked changes in consumer preferences. While IT
purchasers still place strong emphasis on cost minimization, today, there exists
a bigger need among end-users to seek solutions that unify different forms of
communications and help solve specific business problems.
Enterprises require an interactive tool that can incorporate
communications, computing and audio/videoconferencing. This would comprise
technologies that allow people in remote locations to collaborate electronically
via voice or face-to-face, and in real time, and share all types of information,
including data, documents, sounds, and images.
Audio, video, and webconferencing have resulted in huge cost
reductions in travel across geographical boundaries. These benefits come in
various forms: allowing multipoint meetings across time zones and international
borders; reduction in costs of travel and executive time; reduced communication
costs; archiving, whereby conferences could be tapped for future reference;
real-time sharing of files and presentations; improved effectiveness of meetings
with enhanced fluency and focus; bringing together dispersed groups at short
notice; savings on infrastructure costs by opening offices at remote locations,
etc.
Conferencing solutions release the business potential via
attractive economic benefits based on usage of converged resources. It brings
about the organizational agility and the flexibility to work from remote
locations as well, besides providing applications that increase productivity and
efficiency. IP telephony sales are thus likely to grow from 7% in 2002 to 46% by
the end of 2007.
There has been growing demand for managed/hosted solutions as
well. The reasons being the need for reducing capital expenditure, optimizing
internal operations and bringing down operating expenses, enabling rapid
deployment of new applications and services, and leveraging on the specialized
expertise of the vendors, channels, and service providers in managing complex
networks.
Videoconferencing is a significant breakthrough in
communications technology. It has been adopted globally and is being used in
various fields and facets of life, as people are now aware of its innumerable
tangible and intangible benefits. One of the many advantages of
videoconferencing is the possibility to communicate at all levels, including
making use of body language, which plays a significant role in effective
communication. Page(s) 1 2 3 4
