IT FRIENDLY OPTIONS
Easy online services and on-premise software
Nefsis is offered in multiple editions that
span the full-spectrum of IT security policies and desktop management controls:
Nefsis ONLINE an easy, instant conferencing
online service (SaaS),
offering industry standard security for https and SSL/TLS connections. It traverses
firewalls and proxies, and uses standard ports for web services. The Nefsis conferencing
client operates with all desktop settings, including hard lock-down environments.
Nefsis DEDICATED an
on-premise software
solution, providing access point and virtual conference servers on company-controlled
networks. This option is ideal for customers that wish to control physical access to
their servers and limit distribution of conference documents to on-premise facilities.
The installation wizard makes Nefsis Dedicated set-up a breeze. Nefsis
Dedicated is also the best option for customers that require higher than standard
levels of security, or operate under mandates that require use of their security
certificate, certificate authority (CA), public key infrastructure (PKI), or
FIPS 140-2 compliant security settings.
EASY SET-UP AND INSTALL
Live Device Detection, Point-and-Click Audio & Video Device Selection
Nefsis is highly optimized for ad hoc
meetings, making it easy for any new participant to click on a link and join your meeting.
Nefsis automatically detects all audio and video devices, provides warnings for devices that
are still in use by other applications, and automatically tunes the audio input device.
Nefsis acoustic echo cancellation (see AEC below) allows participants to use virtually
any audio input device, even webcam microphones.
Animated Main Share Panel, with Online Meeting Prompts
For the new conference host just starting out, Nefsis provides an animated main sharing panel
with prompts for the typical online meeting process: invite attendees, activate audio/video,
and start sharing materials. The animated share panel and fully-illustrated tool ribbon make
it easy to run your first online meeting.
Unicode & 10 Languages
Nefsis uses state-of-the-art software engineering practices, and is fully Unicode enabled.
The current release supports
10 languages. Nefsis also uses open language files, for modifying
or adding language components, along with a hotkey to dynamically reload them.
MULTIPOINT VIDEO
Fast, Multipoint Video Conferencing
Nefsis uses state-of-the-art image capture and compression technology
to render the best, business-grade, high-quality video images at any video
capture resolution (1/4 CIF or larger). Nefsis uses MPEG-4 image
compression and multi-core, parallel processing (see below for details)
for video encoding, processing and decoding. In addition to performance,
quality and bandwidth improvements, this gives Nefsis complete
independence with regard to video input hardware and displays. With
Nefsis, you can mix-and-match nearly any input device in a multipoint conference;
and Nefsis can display video in tiled, composite, floating,
picture-in-picture and several floating video formats.
High-Quality Video over Any Connection Type / Dynamic Scalable Video Coding
Advanced, multipoint video technology is where Nefsis
outperforms all other competition. Past generations of video codecs
used fixed bitrate encoding. These room-based systems were installed
with dedicated Internet access (or dedicated, point-to-point routes),
and relied on fixed bitrate video encoding. If a conference required
more than two end-points, the addition of multichannel units (MCUs)
or video multiplexers (MUXs) was required. Nefsis was designed from
the ground-up for ad hoc connections, using variable bitrate encoding
(dynamic scalable video). Nefsis is highly tolerant of real-time changes
in latency that often occur over shared connections and the public
Internet. In addition, Nefsis software-based technology manages all
video mixing. There are no MCUs or MUXs required for multipoint
conferences. Today, Nefsis can automatically mix-and-match desktops,
laptops, and conference rooms; webcams, pan-tilt-zoom conference
room cameras, and Telepresence-quality, HD video conferencing over any
TCP/IP connection, dedicated, shared, public or private. These are the
benefits of dynamic scalable video and further abstracting hardware
end-points from a dynamic system.
Automated, Real-Time Throttling Maximizes Video Quality, Without
Monopolizing Your PC
The Nefsis technology described above enables video
conferencing over a wide variety of connection types. But that's not
enough. To deliver an in-person, lifelike quality to your video meetings, Nefsis
balances every participant's video quality, processing power and bandwidth
availability. Nefsis automated throttling governs all three variables, maximizing
quality, yet making sure you have ample processing power for live sharing
and other applications outside Nefsis.
No Limits on Video
Image quality is a function of the video capture hardware and bandwidth
availability at each participant's location. Of course, there are license, user,
and video-feature limits that may be set by a systems administrator.
You can use Nefsis for telepresence-quality video with HD conference room
cameras and sufficient bandwidth; or business-grade video conferencing
with webcams and typical office Internet connections. You can also
conference with any number of participants you desire, 5, 10, 20 or more;
subject to system administrator limits, practical screen space, and
bandwidth considerations.
MULTIPARTY VoIP
Multipoint, Full-Duplex VoIP
Most speaker phones and online meeting products use simplex audio,
meaning only one speaker can talk at a time. Nefsis delivers multipoint,
full-duplex VoIP. All participants that are not muted can speak at any time. Much like
an in-person meeting, you can interrupt the speaker and participants can
interrupt one another while hearing everyone else at the same time.
High-Quality, Wideband Audio Encoding
Nefsis defaults to wideband audio encoding, which renders
audio at a higher quality than landline telephone conferencing. This improved audio quality
further adds to the in-person-like meeting experience.
Multiparty VoIP Synchronization
Nefsis multiparty VoIP is synchronized with other time-dependent,
rich media components such as live sharing and multipoint video. There
are many online meeting products that send live sharing, audio and video
over different connections and protocols without resynchronization, thus
creating distracting lip-sync problems and other time-delays. You don't
see these problems with Nefsis because all data — live sharing,
VoIP and video — is sent over the same connection and synchronized
before delivery.
Acoustic Echo Cancellation
Acoustic echo cancellation (AEC) is a well-known audio technology
that allows the use of microphones instead of headsets, along with
external speakers without causing a feedback loop. This is typical of
conference room scenarios, and becoming more popular with desktop webcams
that ship with built-in microphones. But the science behind many existing AEC products
assumed low-latency, or fixed-latency, between all end-points. This is
not the case with Internet conferencing, where latency times are
different for each end-point, and often change during the course of a
meeting. This explains why so many online meeting solutions revert to
simplex audio (one active talker at a time) when there are more than two
participants. Nefsis AEC, on the other hand, was designed with this
challenge in mind. Nefsis dynamic AEC supports full-duplex, multiparty
connections and highly variable latency times. It is also compatible
with hardware-based AEC components, found in many existing conference
room installations.
Automatic Audio Input Tuning
Nefsis customers report that for the majority of desktop users,
Nefsis automatic tuning is all that is needed for successful VoIP
participation in an online meeting. The visual device-select,
auto-tuning, participant device display, as well as other built-in test
utilities, are additional tools that make conference room installation
and test activities much easier than using hardware products alone.
DISTRIBUTED PROCESSING
Cloud Computing
In
September of 2009, Nefsis was recognized by
Frost & Sullivan as
the first company in the world to apply cloud computing and end-to-end
parallel processing in a multipoint video conferencing application. Using
cloud computing and widely available A/V peripherals is a new approach
to video conferencing. It has several advantages over traditional,
room-based systems; including dramatically simplifying installation and
maintenance, reducing camera costs, and completely eliminating MCUs and
MUXs. Other advantages include mixing and matching desktops, conference
rooms, webcams and HD in the same conference, along with a full-suite of
built-in web conferencing and live sharing tools. Moreover, Nefsis is a
true cloud-computing implementation, and takes advantage of its
distributed architecture to select the best nearby server to deliver the
lowest roundtrip latency times of any online meeting product.
For additional details, please visit our
Cloud Computing page.
End-to-End Parallel Processing
Nefsis uses multi-core, parallel processing end-to-end
(also called multi-core concurrency),
including all its virtual conference servers and all the cores on your
desktop. In most corporate environments, the technology refresh cycle
for desktops is faster than the refresh cycle for installed-site conferencing
equipment. Nefsis brings more processing power to multipoint
conferencing, and it future-proofs your video conferencing investment by
welcoming technology refresh cycles. As processing power grows and your technology
refresh cycle repeats (e.g., Core 2™ Duo, quad core, Windows 7, 64 bit),
your video processing capacity is automatically upgraded too — unlike
traditional solutions which just become obsolete.
MMX/SSE Processor Extensions
Nefsis does not stop at cloud computing and parallel processing.
Nefsis takes advantage of Intel® MMX/SSE multimedia processor extensions
too, off-loading central cores from media-related computation and
further accelerating live sharing and the overall conferencing
experience. It is the combination of cloud computing (best nearby
server), multi-core processing, and processor extensions that ultimately
delivers the fastest multipoint video possible over dynamic Internet
connections.
ENTERPRISE COMMUNICATIONS
Firewall & Proxy Traversal
Nefsis engineering embodies over a decade's development of secure, multipoint
TCP/IP communications in corporate, multi-office environments
(History
of Innovation). Nefsis observes web industry and IT security best
practices for web services (http and https), firewall and proxy traversal.
In addition to supporting the most common proxy standards, Nefsis
incorporates many vendor-specific enhancements to meet real-world
customer scenarios (Squid; Microsoft ISA Server; proxy server installed,
but no proxy client, etc.).
TCP/IP Connection Optimizer
Among the most powerful communications technologies, the Nefsis
connection optimizer represents a tremendous advantage over competing
products. The connection optimizer's technology has evolved over time; selecting the
best connection types or ports when more than two are available, often
trying multiple methods simultaneously, and then selecting the method
with the lowest latency times. This real-time, best-route-selection results
in faster connections and a more responsive conferencing experience.
SECURITY
While many Nefsis technologies, such as cloud computing, parallel
processing, and multipoint video, advance the science of online
meetings, other areas benefit from emphasizing industry standards. The
latter include PC-based audio/video peripherals to reduce cost, web
services (ports, URLs, html, xml) for broad compatibility, and industry
standard security to meet IT policy and regulatory compliance. What is
notable is the extent to which Nefsis embraces the full-spectrum of
enterprise security requirements.
All
Nefsis software and online services use signed code and a third-party certificate provided by
VeriSign.
In addition, Nefsis offers a
multi-layer
security model. It authenticates meetings hosts, and provides conference host,
presenter and participant-level passwords. Hosts can select SSL/TLS security and encrypt all conference
transmissions, end-to-end. Nefsis transports all web
conferencing, VoIP and video data over encrypted TCP/IP connections,
closing many security gaps found in other products (secure data, but unsecure
telephone or unencrypted VoIP).
In addition, for those customers that require it, Nefsis Dedicated Edition
is available for installation on customer networks; providing the ultimate
in physical security and integration points for using customer-specified
certificates, certificate authority, and public key infrastructure. This
includes FIPS 140-2 compliant settings for specific key lengths and algorithms
for signing and encryption.
