Teleconferencing

• Guided By:- Mr.Prakash Singh Panwar

• By:- Shubham Yadav• EC BRANCH 1ST YEAR

TeleconferencingThe word ‘tele’ means distance. The word

‘conference’ means consultations, discussions.Through teleconferencing two or more locations situated at a distance are connected so that they

can hear or both see and hear each other.

• It allows the distant sites to interact with each other and with the teaching end through phone, fax, and e-mail. The interactions occur in real time. This means that the learners/participants and the resource persons are present at the same time in different locations and are able to communicate with each other. In some situations, questions can be faxed/e-mailed early for response by the resource persons

Uses of Teleconferencing

• Education• Training and Development• Business/Corporate

Communication• Governance• Medical Courses/Services

Strengths of Teleconferencing• Accessible to Geographically Dispersed Groups• Communication at National/Regional/Local

Level• Quality Teaching using multiple Teaching

Resources• Real Time Interaction from Remote Target

Groups• Use of Various Teaching Methods enhances

Learning• Cost Effective

Types of Teleconferencing

1. Audio Teleconferencing2. Audiographic Teleconferencing3. Computer Teleconferencing4. Video Teleconferencing5. Business Television Teleconferencing6. Distance Location conferencing

1. Audio Teleconferencing

Audio Conferencing is a two way voice communication among multiple locations in real time. This generally operates through public telephone network. Individual microphones for participants and external speakers at each location are employed in professional systems to carry out conferences in hands free manner

• The number of people that you can connect to would depend on your service provider’s capabilities. In any case it could vary from 3 to 30 beyond which it becomes an Audio Broadcast.

Audiographic Teleconferencing

• Uses narrow band telecommunication channels to transmit visual information such as graphics, alpha-numerics, documents, and video pictures as an adjunct to voice communication.

a

A Web teleconferencing system uses Internet as its communication backbone, web-browser as its client-interface, and web-servers as its server that intercepts and processes the client requests

Cont.…

• Web conferencing is used to conduct live meetings, training, or presentations via the Internet. In a web conference, each participant sits at his or her own computer and is connected to other participants via the internet. This can be either a downloaded application on each of the attendees' computers or a web-based application where the attendees access the meeting by clicking on a link distributed by e-mail (meeting invitation) to enter the conference

Cont.…

• Web conferencing is mostly sold as a service by various vendors. Web conferencing technologies are not standardized, which has been a major reason in the lack of interoperability, clearness, platform dependence, security concerns, service fee and market segmentation

4. Video Teleconferencing

• Video conferencing in its most basic form is the transmission of image (video) and speech (audio) back and forth between two or more physically separate locations.”

Videoconferencing Components

• Cameras (to capture and send video from your local endpoint)

• Video displays (to display video received from remote endpoints)

• Microphones (to capture and send audio from your local endpoint)

• Speakers (to play audio received from remote endpoints)

In Addition, Two Additional Requirements:

• Codec - "compressor/de-compressor“ - 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.

• The Supporting System and the Network Connection

TWO WAY VIDEO CONFERENCING

Point-to-point Conferences

• Point-to-point – A videoconference that connects two locations.

• Each site sees and hears the other sites at all times

Multipoint Conferences

• Point-to-multipoint – A videoconference that connects to more than two sites through the use of a multi-point control unit, or MCU.

• Participants at all sites can hear one another at all times and see the site that is currently speaking.

Benefits of Videoconferencing

• Can improve work quality• Increase productivity• Reduce travel costs• Improves communication• Groups can meet more frequently• Critical meetings can be convened in less time• More faculty and staff can be involved

Benefits of Videoconference-based Learning

• Closely resembles traditional classroom-based education; permits learners to be active participants in the process

• Faculty and staff needs can be met more quickly through just-in-time training

• More faculty and staff can be trained faster without increasing training resources

• Guest lecturers can be easily integrated into the course

Limitations of Videoconferencing

• The absence of QOS (Quality of Service) provides virtually no guarantee of a satisfying and successful experience

• Though the technology is improving, a successful videoconference is dependent upon the connections and technologies at all of the participating sites, AND the network infrastructure

• Security issues

5. Business Television (BTV)

• Is the production and distribution, via satellite , of video programs for closed user grouped audiences, It often has two-way audio interaction component made through a simple telephone line.

6. Distance Location conferencing

• Allows for learning and knowledge exchanges using computers and telecommunication. Can be used to conduct of actual class or to hold meetings among team numbers who are not in the same location.

Why Use a Teleconference?

• Videoconferencing increases efficiency and results in a more profitable use of limited resources. It is a very personal medium for human issues where face-to-face communications are necessary. When you can see and hear the person you are talking to on a television monitor, they respond as though you were in the same room together. It is an effective alternative to travel which can easily add up to weeks of non-productive time each year.

Cont.…

• With videoconferencing, you never have to leave the office. Documents are available, and experts can be on hand. A crisis that might take on major proportions if you are out of town, can be handled because you're on the job. Videoconferencing maximizes efficiency because it provides a way to meet with several groups in different locations, at the same time.

Advantages• Save Time• Lower Costs • Accessible• Larger Audiences • Adaptable • Flexible• Security• Unity• Timely• Interactive

Cont.…

• Saves money as you do not need to travel/ commute to the other person/s location.

• Saves your time and energy.• Latent application like Skype allow you to meet up

with several partner at once, if the video does not work , you also have the option to switch to audio-only way.

• Allows you to observed the body language of the other person, giving non-verbal clues that can help you manage the conversation better

Disadvantages

• Exchange of information is less dynamic than a force.• Decision making process can be slower as you may

need offline to consult far ties and then get break on call.

• Technical issues like power failure , internet connectivity the other party not knowing how to use such technology , etc. , can act an bottle necks, sometimes delaying work and causing you to miss deadline.
