VIDEO CONFERENCING

Videoconferencing is an interactive tool that incorporates audio, video, computing, and communications technologies to allow people in different locations to electronically collaborate face-toface, in real time, and share all types of information including data, documents, sound and picture. In essence videoconferencing removes the barrier of distance that separates us. 

 It

enables one set of people to see and hear people in a different location. In its most basic form is the transmission of image (video) and speech (audio) back and forth between two or more physically separate locations. Also known as “Video teleconference”.

VIDEO CONFERENCING COMPONENTS

CAMERA 

To capture & send video during video conferencing.

MICROPHONE 

To capture & send audio during video conferencing.

Continue…… SPEAKERS To play the audio received during video conferencing.

MONITOR To display the video received during video conferencing.

Continue……. CODEC 

Codec - “Coder Decoder”( COmpressor-DECompressor )- makes the audio/video data "small enough" to be practical for sending over expensive network connections.



A codec takes analog signals, compresses and digitizes them, and transmits the signals over digital phone lines.



Compression rates of up to 1:500 can be achieved.



The resulting digital stream of 1s and 0s is subdivided into labeled packets, which are then transmitted through a digital network.

videoconferencing SYSTEMS Dedicated systems   





Have all required components packaged into a single piece of equipment. Usually a console with a high quality remote controlled video camera. Large group videoconferencing: non-portable, large, more expensive devices used for large rooms and auditoriums. Small group videoconferencing: non-portable or portable, smaller, less expensive devices used for small meeting rooms. Individual videoconferencing: usually portable devices, meant for single s, have fixed cameras, microphones and loudspeakers integrated into the console.

Desktop systems 

Are add-ons to normal PCs, transforming them into videoconferencing devices.

VIDEOCONFERENCING TYPEs Point-to-point • 

A videoconference that connects two locations. Each site sees and hears the other sites at all times

Continue….. Multi-point 

A videoconference that connects to more than two sites through the use of a multi-point control unit( MCU ) or video hub.



Participants at all sites can hear one another at all times and see the site that is currently speaking. ( Voice activated switching)



This is a bridge that interconnects calls from several sources.

Uses of Videoconferencing Business 

Videoconferencing provides businesses with the ability to meet and to work with others over a distance.

Distance Learning   

Saving travel time and expenses. Increasing an instructor's audience. Maintaining the ability for interaction between student

teachers and

CONTINUE…. Telecommuting / Home Office 

Working out of home has never been easier or more practical. Videoconferencing makes it possible to stay connected with people in a very real way.



Videoconferencing allows s to save resources by meeting with clients and/or colleagues via videoconference. This reduces travel expenses, while maintaining face-to-face .

Legal Environment 

The use of videoconferencing technology is becoming more prevalent in today’s courtrooms. Videoconferencing systems are used to enable testifying witnesses to “appear” in court without having to travel to the courtroom.

ETIQUETTE FOR VIDEO CONFERENCING ALLOW A FEW MINUTES FOR SETTING UP AND SHUTTING DOWN THE VIDEO CONFERENCE STICK TO TIME LIMITS  TO MUTE YOUR MICROPHONE WHEN YOU ARE NOT TALKING CONSIDER USING A LOCATION BANNER DON’T MULTI TASK ON CAMERA

Advantages 

It avoids the participants having to spend time travelling to meet each other.



Saves travel costs.



The participants in different locations are able to work on the same electronic document.



Seeing the person that you are communicating with can give important visual clues that are not available during a telephone conversation.



By eliminating time and district barriers, meetings can be hold anytime, anywhere with anyone. In this way, meetings are shorter and more effective. And also with the rich collaboration tools, decisions can be made faster.

Disadvantages A high bandwidth communication link is required to transmit and receive high quality images. There is a short time lag between speaking and receiving a response that can disrupt the natural flow of a conversation. High quality dedicated video-conferencing systems are expensive to buy. Some meetings require a personal touch to be successful. Video conferencing can be less personal than meeting face to face, and it can be possible to miss out on vital body language when you’re struggling with a pixilated image or stuttering video.

Impact on education Videoconferencing provides students with the opportunity to learn by participating in two-ways communication forums. Furthermore, teachers and lectures worldwide can be brought to remote or otherwise isolated education facilities. Students from diverse communities and backgrounds can come together to learn about one another, although language barriers will continue to persist . Such students are able to expose, communicate, analyze and share information and ideas with one another, through Videoconferencing. Students can visit other parts of the world to speak with their peers and visit museums and education facilities. Such virtual field trips can provide enriched learning opportunities to students, especially those in geographically isolated locations and to the economically disadvantages. 

A few example of benefits that videoconferencing can provide in campus environment include : Faculty keeping tours with classes while attending conferences. Guest lectures brought in classes from other institutions. Students interviews with an employer in other cities teleseminars.

ACCESSORIES FOR VIDEOCONFERENCING



Auto-tracking Cameras can follow the speaker and are particularly useful in classroom environments. Document Cameras are used to show live images of hard copy documents and 3D images to the remote end. Scan Converters take a VGA computer display and convert it to NTSC (video) format for display on a video monitor. Video Printers print the television monitor screen image. Videoconference Lighting makes a dramatic difference in how you look to people on the other end of conferences. Videoconference Furniture will be necessary if you are planning to convert your existing conference room into a videoconference room. Video Processors are needed to manipulate video signals from multiple sources
