Video conferencing allows people in different locations to see and hear each other through transmitting video and audio signals. It involves cameras, microphones, speakers and monitors at each location connected through a codec. There are dedicated video conferencing systems designed for large rooms and smaller portable systems for individuals or small groups. Video conferences can connect two locations point-to-point or multiple locations through a multi-point control unit. Video conferencing has applications in business meetings, education, telemedicine and staying connected with friends and family.
First Time Video Conferencing guide by Conference Room Systems covering the following topics. Technology TimeLine, Types of Online Meetings, Common Uses for Video, Migration & Adoption, Preparing for a Launch, Best Practices for Equipment Setup, Setting Expectations and Organizational Goals, Offering “Reduced Travel” benefits and the Conclusion.
Video conferencing allows for synchronous interaction between teachers and distant students through two-way digital video and audio transmission over a network. It provides flexibility for education away from a traditional campus model. While video conferencing equipment can be expensive, costs vary significantly depending on the size and type of system. It enables audio-visual interaction and supports different instructional approaches if clear materials like slides are used. However, both learners and instructors need practice to fully utilize its features. Organizational support through technical staff and facilitators is also needed to ensure stable use.

High Definition The Way Video Communications Was Meant to BeVideoguy
This document discusses the importance of high definition video communications and identifies critical success factors for technology decision makers to consider. It states that new technology promises 10 times the resolution of traditional videoconferencing systems and will dramatically advance video communications from a technical perspective. It identifies key criteria for assessing video communications technology, including visual realism, acoustic realism, and usage simplicity. Visual realism depends on video resolution, bandwidth standards, and camera technology while acoustic realism relies on input quality from microphone architecture and frequency response as well as output quality from spatial audio and minimal distortion.
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.

2. SECTION A
WHAT IS VIDEO CONFERENCING?
At its simplest, video conferencing is a tool which allows users to see and hear
the person they are communicating with. Video conference calls are usually
point-to-point calls which set up a direct link between participants. Calls can
be made locally, nationally or across the world.
Multi-way or multipoint conferences are also possible where more than two users or groups take
part in the call; these will be discussed later.
To make a video conference call each user needs some form of video conferencing system and
access to a suitable communications link.
Video conferencing systems come in a variety of formats - some are computer based, some are
dedicated units - but all have a number of common features:
• Camera
• Microphone
• Speakers
• TV or Monitor
• Methods of establishing a connection to remote users via on-screen options
The choice of system should depend on its intended use. Some systems are only suitable for
person-to-person or small group use; others have the facilities to support use by whole classes.
A video conference allows you to take part in live audio/video presentations in your classroom,
and to collaborate through them.
It is possible to video conference between two classrooms in the same town, or between two
classrooms in different parts of the globe. The distance between each location is only restricted
by the ability of each site to make the required connection.
Live video conferences differ from other multimedia resources, such as video recordings or
television presentations, because they are interactive. You are meeting and talking face
to face with someone else in ‘real time’, but in a different location.
Successful video conferencing in the classroom requires the technology to take a backseat and
allow you to concentrate on the content and delivery of your video conference event or lesson.
Video conferencing is not ‘big and scary’ or too complicated, technical and beyond your
capabilities. It does not need to take up excessive amounts of time, once you have mastered
the basic techniques associated with any new, unfamiliar resource.
Video conferencing is exciting, stimulating, and easy to use with practice and confidence, and
has the potential to totally involve pupils. It is perfectly within the possibilities and capabilities
of what you can achieve in your classroom. The list of resources available to the teacher in the
8 VIDEO CONFERENCING IN THE CLASSROOM
3. SECTION A
classroom is changing and becoming more sophisticated day by day. Equipment based on new
technologies is being developed all the time, extending our ability to communicate and
collaborate with greater ease.
However, it is ultimately the skill and ability of the teacher in harnessing the technology that will
determine the success of video conferencing in the classroom.

WHAT DO I NEED TO GET STARTED?
VIDEO CONFERENCING SYSTEMS
A video conferencing system must be able to fulfil the following tasks:
• Establish a link to another user
Much as a telephone call is made by dialling another user, a video conference call is
made either by dialling the other user’s ISDN number or selecting the network address of
the other user if the unit is on a network. Most systems will have an on-screen address
book or directory in which numbers can be stored.
• Enable the user to hear and see the user at the far-end
(in video conference terminology ‘far-end’ refers to the video conferencing system you are
contacting and ‘near-end’ refers to your end).
All video conferencing systems need speakers and a suitable screen (computer monitor or
television/video monitor depending on the system).
• Provide a means of controlling the sound
This is a major issue. The quality of sound will have a significant impact on the usability
of the system for teaching and learning.
All units need a microphone and speaker. These may be built into the computer if using
a computer-based system or built into the video conferencing system and monitor if using
a dedicated system.
If the microphone and speakers are in close proximity there is potential for sound to loop
between the speakers and the microphone resulting in howling or acoustic feedback.
Some units have methods of controlling sound such as echo cancellation and noise
suppression systems. Others do not have sophisticated sound control and require the use
of a headset for acceptable results.
• Provide a means of controlling the video
A camera is a standard feature on all video conferencing systems. Some are simple,
cheap web cams, others are more complex with automatic focus and gain control. Some
dedicated units include cameras that can be controlled (moved up and down, from side
to side and zoomed in and out) using a remote control. Some can be voice activated
VIDEO CONFERENCING IN THE CLASSROOM 9
4. SECTION A
where the camera will move to focus on the person talking. Some can be controlled from
the far-end, enabling users at the far-end to choose what they want to see.
Many systems have the facility to attach video players, cameras and computer presentations.
Only PC-based systems have the facility to share computer applications. Schools can also use
PC systems linked to the Internet alongside a video conference system to show, demonstrate and
share PC applications simultaneously with their far-end partners.
CHOOSING A VIDEO CONFERENCE
SYSTEM
It is possible to video conference with systems ranging in price from about £50 (in addition to
the cost of a suitable computer) to those costing in excess of £15,000. The choice of system
will depend on how it will be used and the budget available.
CLASSROOM QUALITY SYSTEMS
Experience suggests that there is a number of factors to consider when buying a system which
is suitable for use in the school environment with whole classes, as opposed to systems which
are used for small group or one-to-one conferences.
• Good quality audio which will pick up students speaking from where they sit.
• Good quality camera with auto focus, contrast and brightness.
• Remote controlled camera - controlled from a handset with the ability to pre-set positions
(e.g. to pick out participants at the touch of a button).
• Mute facility to easily mute outgoing audio at the touch of a button.
• Ability to support a range of display devices including TV, plasma, video/data projector,
interactive whiteboard.
• Ability to plug in a video player, camcorder, document camera or digital stills camera to
present video or images to the far-end.
• Ability to plug in a video recorder to record conferences.
• Ability to plug in a laptop (or connect via a network) to share applications such as
PowerPoint presentations.
In general this range of facilities is only available on Group Systems (see below).
TYPES OF VIDEO CONFERENCE SYSTEM
Most units fit into one of three broad categories:
• Low-cost, computer-based systems
• Desktop Systems
• Group Systems
These descriptions of the types of system available give an initial guide as to the most suitable
type of system for a particular application. Budget will certainly be a significant factor but the
purchase of inappropriate equipment can prove to be a false economy.
10 VIDEO CONFERENCING IN THE CLASSROOM
5. SECTION A
Which communications link, ISDN or IP, to use is another important issue. This will be
determined by who a school plans to link with, i.e. will links be with users connected via ISDN,
IP or both? (See Communications Links below).
LOW-COST, COMPUTER-BASED SYSTEMS
Most new computers, particularly multimedia systems, already have speakers and a
microphone. By adding a low-cost camera, such as a web-cam, it is possible to video
conference across a network or the Internet. Suitable only for personal one-to-one conferences
where the quality of sound and picture is not critical.
Cost Range: In the region of £50 for a camera to add to an existing computer
DESKTOP SYSTEMS
A small unit, which includes the camera, is connected to a computer. The unit may include echo
cancellation to control the sound and will usually incorporate the microphone and camera and
may include the speakers. These units are primarily used for network-based conferencing.
Suitable for personal one-to-one conferences or small group use. Can be used across ISDN or
networks depending on model.
Cost Range: In the region of £400 - £900 to add to an existing computer
VIDEOPHONES
Videophones also fall into the category of desktop systems. As its name implies it is a telephone
unit with a small built-in screen and camera.
They can connect with other videophones or the more expensive dedicated units.
Control of the sound is good, enabling hands-free calls to be made. Additional cameras and
monitors can be attached. Suitable mainly for individual use or groups of two or three. Good
for one-to-one meetings. Can be used in multipoint conferences.
Cost Range: £600 - £1200
GROUP SYSTEMS
There is a range of self-contained units available in this category. Most sit on the top of a normal
television and use the television for picture and sound, or they can be linked to a data projector.
The unit may contain the microphone or have a table microphone attached. The camera is
usually built in as part of the main unit. All functions, including camera movement, are usually
controlled by a remote control or remote keyboard.
Some units support the use of dual screens (one to show the near-end, a video being played or
an image from a document camera and the other to show the far-end). Suitable for all uses from
one-to-one up to whole-class use.
Cost Range: £2500 - £15,000 plus
For more detail about the types of systems available, see Section G.
VIDEO CONFERENCING IN THE CLASSROOM 11
6. SECTION A
COMMUNICATIONS LINKS
A communications link is required, over which a video conference is established. A video
conference signal requires more capacity than a normal, voice-only phone line can provide. A
video conference system will use either an ISDN link or network (IP) based link. Some systems
can use both. Classroom-quality video conferencing requires a minimum bandwidth of 128K.
This might be ISDN or IP connectivity.
Key issues are the bandwidth of the link and quality of service of the link. Greater bandwidth
can give better quality picture and sound. There are a number of technical constraints that might
affect your bandwidth and the quality of service that you can achieve.
ISDN (Integrated Services Digital Network)
ISDN is a dial up service but as its name implies is a digital service. ISDN can be supplied in
a number of configurations; the most common used for video conferencing is the ISDN 2e
service.
Being dial-up it is used in much the same way as a normal telephone line. It is simply a matter
of dialling the number of the far-end; a direct link is then established for the duration of the call.
Both users must have compatible ISDN lines installed and have ISDN compatible video
conferencing equipment. ISDN is implemented worldwide, opening up the possibility of
conferencing with users in different countries. ISDN is currently a reliable option for video
conferencing.
In the UK ISDN services are available from British Telecom and in some regions are also
available from other suppliers such as cable companies. Because it is a dial-up service it is
paid for according to the destination and the duration of the call. There is also a rental charge
for the ISDN service. (For more details of charges see ‘Running Costs’ below.)
More details of ISDN are given in Section G.
IP-BASED VIDEO CONFERENCING
IP-based video conferencing is conferencing across computer networks. IP video conferencing
is only possible across networks with sufficient capacity available for the conference.
Networks within a school generally have sufficient capacity to support video conferencing.
Although the capacity of a network may be known, the number of users sending data across
the network at a particular time will also affect the performance of a video conferencing system.
Broadband networks connecting schools is making local and regional IP-based conferencing
more of a possibility; this is because the network is effectively a private network linking the
schools. There is a number of technical and performance issues that have to be addressed when
video conferencing within and between networks.
The Regional Broadband Consortia (RBCs), which manage the regional grids for learning, are
implementing a variety of approaches for providing video conferencing via broadband. For
more information on RBCs see the BECTa website http://broadband.ngfl.gov.uk.
12 VIDEO CONFERENCING IN THE CLASSROOM
7. SECTION A
It is also possible to video conference across the Internet but because there is no guarantee of
capacity from one end of a link to the other the results can be unpredictable. Points of
congestion will interrupt the continuous audio and video stream. This means that video
conferencing across the Internet is less suitable for an educational situation where a teacher is
relying on the conference working as part of a lesson.
More details of IP video conferencing are given in Section F.
WHAT COMMUNICATIONS LINK TO USE?
The choice of communications links will mainly depend upon who you plan to conference with.
Schools purchasing equipment should consider the need for systems that will support both ISDN
and IP-based conferencing. Where schools are moving from ISDN to broadband for their
Internet access it is worth considering retaining the ISDN line for video conferencing with other
ISDN-based users until a gateway is available for them to use.
The choice of communications link will mainly depend upon who you plan to conference with.
Many organisations that schools conference with are ISDN based, although many larger
organisations are considering the use of IP-based systems. IP has the advantage of being free
of call charges. Over time there is likely to be an increasing move to IP-based conferencing as
the technical issues are resolved. (See Section F.)
Because the two systems are very different, a ‘gateway’ between the two is required to
conference between ISDN and IP. This equipment would not normally be set up in a school but
may be provided as part of a regional or national network. The use of a gateway will allow
schools to use IP only based conferencing systems and make ISDN calls via the gateway. The
school would not then need its own ISDN line for video conferencing. Schools should check to
see if their RBC has or is planning to set up a gateway.
CREATING THE RIGHT ENVIRONMENT
Although video conferencing equipment can be used in most environments, there is a number
of factors that will enhance the experience for you and those at the far-end.
The requirements of the environment are linked to the type of system you are using. For
example, a PC-based system used with a headset can be used in all but the noisiest
environments, but a dedicated system with a sensitive microphone will pick up every sound
within a room.
The following guidelines relate primarily to the use of Group Systems with a class or larger
group and they suggest the ideal environment. Many schools will not be able to take on board
some of these points without dedicating a room to video conferencing; however, some factors
simply relate to how a room and participants are arranged.
VIDEO CONFERENCING IN THE CLASSROOM 13
8. SECTION A
SOUND
It is considered that 85 per cent of the information disseminated in a video conference is
delivered aurally, so getting the audio right is a high priority.
• Choose a room that is acoustically ‘dead’. Ideally, it should be carpeted and have ‘soft’
wall covering such as hessian boards or curtains. A good test is to stand in the room and
speak loudly. If you hear a reverberation or echo, the video conference system will too.
The worst case scenario is to have glass walls as the sound reflects off them. Bear in mind,
though, that people act as baffles; the more people in a room the better, and often a very
reflective room will be perfectly useable with five to ten people in it.
• Switch off any heaters or air-conditioning systems that produce a ‘hum’. These will be
picked up by sensitive microphones, making it difficult to hear quiet voices. The air flow
itself can also have a severe effect on audio input. A simple test is to place a tissue on
the table by the microphone to see if it disturbed by airflow. If it is, the audio may be
affected.
• The room should be as undisturbed as possible by external noise. A camera that is set to
track voices and focus on the person talking can be ‘fooled’ by other noises. Multipoint
conferences often rely on the voice of a contributor to switch to the person talking - again
other noises in the room can ‘fool’ the system. Use of camera ‘pre-set’ buttons often helps
in a ‘formal’ environment.
• The space should be laid out so that those taking part are equidistant from the
microphone - ideally between three and five metres.
• Know how to MUTE your system. Muting switches off your microphone, which is
particularly important when listening to contributions from the far-end. Use of the mute is
especially important during multipoint conferences to avoid the audio control switching to
your camera at the wrong time.
LIGHTING
• It is not normally necessary to bring in specialist lighting. Most modern systems have the
ability to adjust to local conditions with specific software controls. However, it is important
to have some control over natural and artificial lighting. In practice, if a room is to be
used regularly, it is better to cut out natural lighting and use artificial lighting, over which
you have control.
• Lighting should fall on the faces of those taking part in the conference to give a good
picture to the far-end. The key to good lighting is to have no shadows. Shadows
effectively double the amount of movement the video conference system has to process
and thus the video quality can be significantly reduced. A simple test is to place your
hand about one foot from the top of the table surface where most participants will be. If
you can see a significant shadow the lighting is too direct. To reduce this effect use as
many diverse lights as possible. Diffusers can be placed over fluorescent lights. A light-
coloured table top, avoiding white, helps reflect light into the faces of the participants,
increasing image quality.
• Don’t sit in front of a window - this will produce good silhouettes but will mask the detail
of faces. Avoid strong backlighting from windows or low lights behind those taking part.
• Turn off any computer screens that are in view.
14 VIDEO CONFERENCING IN THE CLASSROOM
9. SECTION A
BACKGROUND
• Avoid cluttered backgrounds. A single-colour background, perhaps with a sign or logo to
identify the school, is better than lots of pictures, work or posters. A plain pastel colour is
best - a pale blue is a good colour to start with.
ARRANGEMENT OF THE ROOM
This will depend upon the type of conference and the number of people involved but the
following guidelines will help:
• Ensure that all those taking part are in the camera shot, ideally facing the camera and
not obscured by rows of computer monitors. The less unnecessary furniture in the room,
the better. Avoid sitting around a huge conference table.
• Ensure that those speaking can be clearly identified.
• If numbers involved are small, aim for a ‘head and shoulders’ shot of the participants.
• If numbers are large, it may be necessary to move those contributing nearer to the camera
and microphone for parts of the conference - however, aim to keep movement to a
minimum.
• Ensure that all those taking part can see the screen. A large television is usually sufficient.
The signal from the unit can be projected using a data projector, but this can sometimes
result in a poor resolution picture, so experiment before use.
• The camera should be positioned close above or below the screen, and presenters should
look directly at the camera so it appears to those watching at the far-end that they are
looking directly at them.
DRESS
• Because video conferencing cannot reproduce fast movements or quickly changing areas,
it is better to wear plain clothing - avoiding stripes or chequered patterns. Some bold
colours, particularly reds, do not work well.
USING OTHER COMPUTER
APPLICATIONS WITH VIDEO
CONFERENCING
It is possible to show applications such as PowerPoint to the audience at the far-end.
It is also possible to share applications, such as Microsoft Word or Excel, so that changes made
by one user will be seen by the other. This enables collaborative work on documents, drawings
or data to take place whilst a video conference is in progress.
This can be done using some video conferencing systems or via the Internet. For more details
see Section F.
VIDEO CONFERENCING IN THE CLASSROOM 15
10. SECTION A
St Peter’s High School in Exeter linked with their partner school in Bamberg, Germany to share
a Mathematics lesson. The teacher in Exeter taught both classes using a software application
called Omnigraph which allows the user to create graphs and see the effect of changing
variables. The application was shared so that the users at both ends could see the graphs being
created during the lesson and see the teacher.
MULTIPOINT CONFERENCES
Conferencing between two sites is called ‘point to point’. When there are more than two sites
it is called ‘multipoint conferencing’.
Multipoint Conferencing Units (MCUs) facilitate conferencing between more than two sites at
the same time. MCUs act as a central bridging device that can link a number of users into a
single conference. An MCU is often referred to as a ‘bridge’.
The style of the conference may dictate how many users it is sensible to link at any one time.
For example, when a high degree of interaction between all the users is expected, it is usual to
restrict the conference to three or four other users. Where one centre is simply presenting, then
more could be linked.
In practice, each centre will dial into the MCU and will be connected into the conference. There
are two common methods for controlling who is on screen at any one time:
• Continuous Presence - where each centre is on all the screens all the time, usually
displayed in a portion of the screen, e.g. four centres - each in a quarter of the screen.
• Voice Activated or Audio Follow - where the centre which is speaking at that time is shown
full screen.
MCUs can be expensive pieces of equipment and the centre that hosts an MCU must have
adequate incoming communication links. With the reduction in the cost of MCUs and the
increased availability of group systems that include multipoint capability, some larger
organisations such as local authorities are purchasing their own systems.
Currently some regional broadband grids are considering implementing MCU support.
A number of companies offer multipoint conferencing as a service. This service is usually
charged based on the number of systems connected and the duration of the call.
