Data Communication. Display and reproduction of transmitted signal. Types of Video Conferencing : Types of Video Conferencing Dedicated Video Conferencing Suites Special hardware required Dedicated Communication links such as ISDN Drawbacks :- Costly Desktop Video Conferencing Webcams & Multimedia Phones required Internet Connection that allows multimedia communication Drawbacks :- Bandwidth & Proxy limitations Mobile Video Conferencing Just a Mobile with 3G services Drawbacks:- Low quality Requirements : Requirements Installed Webcam, Head-Phones Any web-browser with flash player installed. Internet connection for connecting Video Server User credentials for connecting the server. Video Quality Parameters : Video Quality Parameters Frame Rate: This parameters define how many frames are displayed in one second. Frame Resolution: Dimensions of each frame. Frame Quality: Compression of each frame. Bitrate: Supported on specific Video Formats Bandwidth & Video Quality - Relation : Bandwidth & Video Quality - Relation Bandwidth also known as bit rate, is rate of data transfer measured in bits per second. Higher the Video Quality we prefer, higher bandwidth is required. Video Quality has to be adjusted to meet the current bandwidth available. Prefers bandwidth of 512kbps at client. Benefits of Videoconferencing : Benefits of Videoconferencing Can improve work quality Increase productivity Reduce costs Improves communication Groups can meet more frequently Critical meetings can be convened in less time More faculty and staff can be involved Slide 11: Thank You!!!!!
