Communications Technology data rate
Video Conferencing Data Rate A small business has acquired a video-conferencing suite of software, which will run in the top left quarter of the monitor with a screen resolution of 800x600 pixels. The video frames to display use 256 colours and have a refresh rate of 25 frames per second, (fps). ... The maximum data rate in bits/s is to be calculated to decide if the present system is sufficient. ... 25 = 120,000 pixels Refresh rate @ 25fps * Resolution = 25 * 120,000 pixels = 3,000,000 pixels 256 colours @ 1 byte * Display = 1 byte * 3,000,000 pixels = 3,000,000 bytes Data rate in bits = 8 * 3,000,000 bytes = 24,000,000 bits = 24 Mbits/s The above calculations show, the data rate required to sufficiently run the video conferencing suit of software would be 24 Mbits/s for each channel.
