Tele conferencing and video conferencing

  1. 1. AKHILESH YADAV(IMB2010008) TAPAS GIRI(IMB2010031) SHRESHTAMITTAL(IMB2010045)
  2. 2. Teleconferencing  The 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.
  3. 3.  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
  4. 4. Uses of Teleconferencing  Education  Training and Development  Business/Corporate Communication  Governance  Medical Courses/Services
  5. 5. 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
  6. 6.  Types of Teleconferencing
  7. 7. AUDIO COFERENCING 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
  8. 8.  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.
  9. 9. Videoconferencing – What Is It?  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.”
  10. 10. 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)
  11. 11. 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
  12. 12. TWO WAY VIDEO CONFERENCING
  13. 13. Point-to-point Conferences  Point-to-point – A videoconference that connects two locations.  Each site sees and hears the other sites at all times
  14. 14. 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.  Voice activated switching
  15. 15. 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
  16. 16. 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
  17. 17. 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
  18. 18. 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.
  19. 19.  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
  20. 20.  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
