- 2. Main Topics p What is HD video conferencing Problems in current VC over UDP Improving video quality with TCP Problems of VC over TCP Getting real time video with TCP real-time Q&A
- 3. What is HD video conferencing g HD video conferencing provides more visual information than any standard-definition format, for virtually every meeting environment, from Tele-presence, to group systems, to executive desktop video solution. Dallas Paris
- 4. Problems of current VC over UDP Some of the most common video problems over unreliable UDP protocols, are related to video quality, such as greenish, pixelization, blocky, and distorted i t di t t d picture.
- 5. Improving video q p g quality with TCP y Video conferencing stream could be carried over TCP to gain advantage of TCP’s as a: Reliable protocol Congestion control
- 6. Problems of VC over TCP TCP connections could introduce significant delay and throughput variations in the delivery of video data
- 7. Getting real-time video with TCP g Table below shows the relation between variable frame rate with the bandwidth consumption, for 720p HD video stream, as an average for low, medium, and hi h movement. l di d high t 3000 2500 2000 Bandwidt (kbps) 1500 th 1000 500 0 1 3 5 7 9 11 13 15 17 19 21 23 25 Frame rate (fbs)
- 8. Getting real-time video with TCP g Our solution to cope with the changing in network BW is to have a dynamic frame rate and bandwidth calibration mechanism. High bandwidth Low bandwidth
