This paper proposes an adaptive energy management policy for wireless video streaming between a battery-powered client and server. It models the energy consumption of the server and client based on factors like CPU frequency, transmission power, and channel bandwidth. The paper formulates an optimization problem to assign optimal energy to each video frame. This maximizes system lifetime while meeting a minimum video quality requirement. Experimental results show the proposed policy increases overall system lifetime by 20% on average.
Microsoft PowerPoint - WirelessCluster_PresVideoguy
This document analyzes delays in unicast video streaming over IEEE 802.11 WLAN networks. It describes conducting an experiment using a testbed with a Darwin Streaming Server and WLAN probe to capture packets. The analysis found that video bitrate variations, packetization scheme, bandwidth load, and frame-based nature of video all impacted mean delay. Bursts of packets from video frames caused per-packet delay to increase in a sawtooth pattern. Increasing uplink load was also found to affect delay variations.
Proxy Cache Management for Fine-Grained Scalable Video StreamingVideoguy
This document proposes a novel video caching framework that uses MPEG-4 Fine-Grained Scalable (FGS) video with post-encoding rate control to achieve low-cost and fine-grained rate adaptation. The framework allows clients to have heterogeneous bandwidths and enables adaptive control of backbone bandwidth consumption. It examines issues in caching FGS videos, such as determining the optimal portion to cache (in terms of length and rate) and optimal streaming rate to clients. Simulation results show it significantly reduces transmission costs compared to non-adaptive caching while providing flexible utility to heterogeneous clients with low computational overhead.
The document compares Microsoft Windows Media and the Adobe Flash Platform for streaming media. It discusses key differences like user experience, workflows, and playback reach. Flash offers more flexibility in creative expression, richer interactions, and wider device playback than Windows Media. It also has a 98% install base, making it easier for viewers to watch streams without extra software. The document outlines workflows for experience design, programming, broadcasting, production, and more using Flash tools versus Microsoft alternatives.
Free-riding Resilient Video Streaming in Peer-to-Peer NetworksVideoguy
This document summarizes a PhD thesis about free-riding resilient video streaming in peer-to-peer networks. The thesis contains research on two approaches: tree-based live streaming and swarm-based video-on-demand. For tree-based live streaming, the thesis presents the Orchard algorithm for constructing and maintaining trees to distribute video in a peer-to-peer network. It analyzes attacks on Orchard like free-riding and evaluates Orchard's performance under different conditions through experiments. For swarm-based video-on-demand, the thesis introduces the Give-to-Get approach for distributing video files and compares it to other peer-to-peer protocols. It evaluates Give-to-Get's performance in experiments
BT has developed Fastnets technology to improve video streaming. It avoids start-up delays and picture freezing during congestion. Fastnets streams multiple encoded versions of the video at different data rates and seamlessly switches between them based on available bandwidth to maintain quality without pausing. This allows for near-instant start times and reduces bandwidth usage by up to 30%. Fastnets provides a high-quality video streaming solution for both mobile and IPTV applications.
This document summarizes recent research on video streaming over Bluetooth networks. It discusses three key areas: intermediate protocols, quality of service (QoS) control, and media compression. For intermediate protocols, it evaluates streaming via HCI, L2CAP, and IP layers and their tradeoffs. For QoS control, it describes how error control mechanisms like link layer FEC, retransmission, and error concealment can improve video quality over Bluetooth. It also discusses congestion control. For media compression, it notes the importance of compression to achieve efficiency over limited Bluetooth bandwidths.
The document discusses video streaming, including definitions and concepts. It covers topics such as the difference between streaming and downloading, common streaming categories like live and on-demand, protocols used for streaming like RTSP and RTP, and the development process for creating streaming video including content planning, capturing, editing, encoding, and integrating with servers.

The document discusses considerations for creating video content that can be streamed over mobile networks with restricted bandwidth like 3G-324M. It covers topics like video basics, codecs, profiles and levels, video streaming techniques, guidelines for authoring mobile-friendly content, and tools for analyzing video streams. The goal is to help content creators optimize video quality for low-bandwidth mobile viewing.
ADVANCES IN CHANNEL-ADAPTIVE VIDEO STREAMINGVideoguy
This document summarizes recent advances in channel-adaptive video streaming. It reviews adaptive media playout at the client to reduce latency, rate-distortion optimized packet scheduling to determine the best packet to send, and channel-adaptive packet dependency control to improve error robustness and reduce latency. It also discusses challenges for wireless video streaming and different wireless streaming architectures.
Impact of FEC Overhead on Scalable Video StreamingVideoguy
The document discusses the impact of forward error correction (FEC) overhead on scalable video streaming. It aims to address uncertainty about the benefits of FEC and provide insight into how FEC overhead affects scalable video performance. The motivation section explains that FEC is often used for streaming to overcome packet loss without retransmission. However, previous studies have reported conflicting results on the benefits of FEC. The background section provides details on media-independent FEC schemes.
The document proposes a cost-effective solution for video streaming and rich media applications using Vela's RapidAccess video server combined with iQstor's iQ1200 SATA storage system.

4. Nefsis IT-Friendly Options
Your Choice: Easy online services or on-premise software
Nefsis is offered in multiple editions that span the full spectrum of IT security policies and
desktop management controls.
Nefsis Online is an easy, instant conferencing online service. Nefsis Online employs the
industry’s most advanced security standards for https and SSL/TLS connections. It traverses
firewalls and proxies, and uses standard ports for web services (80 and 443). The Nefsis
conferencing client operates with all desktop settings, including hard lock-down
environments (the latter requires a component download for each conference).
Nefsis Dedicated is an on-premise software solution providing access point and virtual
conference servers on company-controlled networks. This option is ideal for customers who
wish to control physical access to their servers and limit distribution of conference
documents to their on-premise facilities. The installation wizard makes set up easy. Nefsis
Dedicated is also the best option for customers who require higher levels of security or
operate under mandates that require use of their certificate, certificate authority, public key
infrastructure or FIPS 140-2 compliant security settings.
Easy Set Up & Go
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 allows participants to use
virtually any audio input, even webcam microphones.
Animated Main Share Panel with Online Meeting Prompts
For the first-time conference host, 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 is fully Unicode enabled. The current release supports 10 languages, with more
planned. Nefsis will default to the participant’s browser or O/S language settings, as
appropriate. Nefsis uses open language files for modifying or adding language components,
along with a hotkey to dynamically reload them.
Nefsis White Paper Page 4 www.nefsis.com
5. Multipoint Video
Fast, Multipoint
Video Conferencing
Nefsis uses state-of-the-art
image capture and
compression technology to
render the best, high-quality
video images at any capture
resolution. Nefsis uses MPEG-4 image compression and multi-core, parallel processing for
video encoding, transmission 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 any input device in a
multipoint conference; and Nefsis can display video in tiled, composite, floating, picture-in-
picture and floating "video bar" formats.
High-Quality Video over Any Connection Type
Advanced, multipoint video technology is where Nefsis excels. 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 required matched
bandwidth. If a conference required more than two end-points, the addition of multichannel
units (MCUs) was required. Nefsis was designed from the ground up for ad hoc connections
and uses variable bitrate encoding. Nefsis is highly tolerant of real-time changes in latency
that often occur over shared connections and the public Internet. In addition, Nefsis
manages all video mixing — there are no MCUs required for multipoint conferences. Today,
Nefsis can mix and match laptops, desktops, conference rooms, webcams, pan-tilt-zoom
(PTZ) conference room cameras and HD over any TCP/IP connection, whether dedicated,
shared, public or private.
Automated Throttling
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 throttles and 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 Quality
Image quality is a function of the video capture hardware (i.e., the camera) and bandwidth
availability for each participant. Given adequate bandwidth (mbps), you can use Nefsis for
telepresence quality and multipoint, HD video conferencing. 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.
Nefsis White Paper Page 5 www.nefsis.com
6. Multiparty VoIP
Multipoint, Full-Duplex VoIP
Most speaker phones and online meeting products use
simplex audio (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 hear others,
interrupt the speaker and talk at the same time.
High-Quality, Wideband Audio Nefsis is full-duplex. Multiple participants can speak
Nefsis defaults to wideband audio encoding, which simultaneously. You can see who is speaking by
renders audio quality better than landline telephone looking at their video (bordered in green); and for
conferencing. The improved audio quality further adds those participants with no video input, their name is
to the in-person-like meeting experience. highlighted on the conference list.
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 data over different connections and protocols without re-
synchronization, thus creating distracting lip-synch problems and other time delays. Meeting
hosts and participants do not see these problems with Nefsis because all data — live sharing,
VoIP and video — is sent over the same connection and synchronized before play.
Acoustic Echo Cancellation
Acoustic echo cancellation (AEC) is a well-known audio technology that allows the use of
separate speakers and microphones, instead of headsets. This is typical of conference room
scenarios and becoming more popular with desktop webcams that ship with built-in
microphones. The science behind many existing AEC products assumed low-latency or fixed-
latency between all end-points. This explains why Internet VoIP conferencing often sounds
so poor (the assumptions do not hold), and why so many vendors drop to simplex audio
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. Customers can also elect to override default Nefsis
settings and use hardware-based AEC found in many existing conference room installations.
Automatic Audio Input Tuning
Nefsis customers report that, for the majority of desktop users, Nefsis automatic audio
input tuning is all that is needed for successful VoIP participation. In addition, Nefsis
provides several built-in tools for going beyond headsets and webcams; including visual
device selection, remote participant device displays and built-in test utilities. These point-
and-click features make it easier to configure desktops and rooms than using hardware
products alone.
Nefsis White Paper Page 6 www.nefsis.com
7. Built-In, Live Collaboration
The same communications framework that supports multipoint VoIP
and video also supports Nefsis live data sharing. All three data types
— live sharing, VoIP and video — are sent over the same TCP/IP
connection. Nefsis throttles image quality, CPU and bandwidth
availability for each participant, synchronizing all data before display.
In this manner, Nefsis provides the most seamless web, VoIP and
video conferencing experience possible.
Share Anything Accessible
A Nefsis presenter can share anything accessible to their desktop
computer, including documents, presentations, desktops, applications
and more (see tool ribbon above). When sharing documents, the rich
media content is sent only once and the resulting display includes the
original text, vector and raster components. Only the raster images
are compressed if needed. This results in a high-quality, clean and
crisp display. Every page has a thumbnail on the user interface, so
the presenter can easily page back and forth.
More Collaboration Features
For working meetings, Nefsis users can take advantage of live
annotation, remote control, white boards, file hand-outs and many
other features (see tool ribbon above) for a truly collaborative, online
meeting environment.
Complete Rich Media Capabilities
Nefsis meeting hosts can record their online meeting, including all live
sharing, VoIP and video. The result is a complete rich media recording
of everything that transpired in the meeting. The recording output is
saved in an industry standard format (FLV, AVI). Customers are not
locked into any proprietary formats and they can edit or further Top: PowerPoint presentation sharing

8. 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. Other advantages include mixing and matching desktops, conference rooms, web-
cams 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 on Nefsis cloud computing, please visit:
http://www.nefsis.com/How-Multipoint-Conferencing-Works/index-multipoint-video-conferencing.html
End-to-End Parallel Processing
Nefsis uses multi-core, parallel processing end-to-end, including all its virtual conference
servers and all the cores on the user’s 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 a multipoint application
and it future-proofs customer video conferencing investments. As processing power grows
and the customer’s technology refresh cycle repeats (e.g., Core 2™ Duo, quad-core, 8-core,
Windows 7 64 bit, etc.), video capabilities are automatically expanded. This is unlike self-
contained hardware products which are left behind by technological advances.
MMX/SSE Processor Extensions
Nefsis does not stop with 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. Nefsis observes IT best practices
for web services (URLs, http, xml, ports), security, 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 (e.g., Squid installation, Microsoft ISA
Server installation, installed proxy server, but no proxy client, etc.).
Nefsis White Paper Page 8 www.nefsis.com
9. TCP/IP Connection Optimizer
Among the most powerful communications technologies, the Nefsis connection optimizer
represents a tremendous advantage over competing products. The connection optimization
technology has evolved over time, selecting the best connection type or port when two or
more are available. Nefsis often tries multiple connection methods simultaneously and then
selects the method with the lowest latency time. This real-time selection process 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 includes PC-based audio/video peripherals to reduce cost;
web services (URLs, html, xml, ports) for broad compatibility; and
industry standard security to meet 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. Nefsis offers a multi-layer security model. It authenticates meeting 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 over one encrypted TCP/IP connection, closing many
security gaps found in other products (e.g., secure data, but unsecure telephone or
unencrypted VoIP).
In addition, for those customers that seek more controls, Nefsis Dedicated 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. Nefsis Dedicated is available at the same price as
Nefsis Online, even for smaller installations.

Built-In Bandwidth Monitor & Network Diagnostics
Bandwidth Monitor
The Nefsis Bandwidth Monitor allows IT staff to
visually display the bandwidth consumption between
a conference participant and the virtual conference
server. It displays the total uplink bandwidth
consumption, along with Audio, Video, Desktop and
Document sharing components.
Nefsis White Paper Page 9 www.nefsis.com
10. Bandwidth Test
When the Bandwidth Test is applied, Nefsis will determine the available bandwidth
between the Nefsis conference participant and the virtual conference server, both uplink
and downlink, at that point in time. Generally, higher bandwidth means a better
conferencing experience. Some applications such as multipoint HD require substantial,
mbps bandwidth availability.
Latency Test
The Latency Test is very useful for plotting the “delay” on an internet connection between a
participant and the conferencing server over time. Lower latency (delay) means better
conferencing. Cell phone latency is typically 200 milliseconds (2/10ths of a second). Any
latency higher than 200 milliseconds is considered poor. This test is also useful for spotting
intermittently high latency times as often occurs on wireless connections or proxy
connections where the proxy is overloaded.
Routing Test
The Routing Test is a comprehensive analysis which displays the Internet route between a
conference participant and the conference server. It takes a snapshot of response times at
various hops to help identify where delays occur.
Summary
Using cloud computing, parallel processing and standard audio/video peripherals is a new
approach to multipoint video conferencing. It delivers the same video quality as traditional
hardware solutions, while dramatically lowering the installation effort, major equipment
expense (CAPEX) and on-going complexity. In addition, Nefsis has better reach — to any
desktop or conference room worldwide, webcam to HD — and offers built-in, live
collaboration tools.
With future technology refresh cycles, Nefsis customer installations benefit from the addition
of multi-core processors, unlike traditional video conferencing box solutions which quickly
become obsolete.
History has shown that the benefits of reducing costs and complexity have led online
services and standardized components to category leadership. For example, SalesForce.com
has become a leading supplier of CRM solutions in a once-crowded market. Nefsis delivers
the same customer benefits to multipoint video conferencing applications, representing the
best, most cost effective video conferencing investment for its customers.
