NERA Video Communicator (NVC)
Global Satellite Video Conferencing Solution
With the NVC briefcase-sized mobile video
conferencing solution, you can hold video
meetings anywhere, anytime via satellite or
terrestrial ISDN.
It is uniquely designed to go with the Nera
WorldCommunicator (NWC), a portable
satellite data terminal that provides Inmarsat
64 kbps/ISDN worldwide.
High Quality Video Encoding Algorithm
The NVC uses H.264, the latest video encoding jointly developed by ITU and MPEG Group.
H.264 provides a far more efficient mechanism for compression and decompression of
motion video. It requires less bandwidth and for video conferencing, H.264 uses 50% of the
bandwidth needed by previous video format to achieve the same quality of video. It is also
backward compatible with earlier video format.
Saving Of Airtime Charges
With the reduced bandwidth requirement, there will be savings of airtime costs since a 64
kbps link is able to provide the same quality as a 128 kbps link. There will also be a
reduction of equipment costs, as less communication equipment is needed.
Securing Your Communication Link
NVC provides embedded and easy to use standard based encryption technology. It
supports point-to-point and multipoint calls with DES and AES encryption via automatic key
generation and exchange.
Able To Fit The NWC Into The Same Box Of The NVC
The NVC is specially designed with users’
needs in mind. It is able to house the NWC
and other accompanying accessories within
the same box. This is to ease transportation
and deployment for field work. It is compact
and greatly enhances portability. It has builtin battery to support remote deployment with
the NWC.
Other Applications Features
The system has moveable picture-in-picture that allows users to view a small image of
themselves. It can store up to 100 names and video or telephone numbers in the global
directory. It supports 11 languages including English, Chinese, Japanese, German, French
and Russian. It also allows external connection to camera, microphone and projector. It
supports IP or ISDN and even wireless LAN. The remote control also enables ease of use
and the selection of menu is rather intuitive.
A Rugged And Portable Video Conference
Solution Of Choice
Inter-operation between the NVC and NWC is
simple and easy to deploy and use. There is a
single cable connection between the NVC and
NWC. With the remote control, making a call
involves only a few clicks of the preset buttons.
The combination of the NVC and the NWC
provides an unbeatable solution for remote
satellite based video conferencing.
Possible Usage of The NVC
The NVC is an ideal video conferencing solution designed for field and outdoor usage.
Transmitting of video images in remote areas is a key requirement for journalists, military
personnel and other field users like those working in the oil & gas industries. Others in the
emergency rescue and disaster recovery areas will also find that the NVC together with the
NWC is a combination of convenience.
