High-Bandwidth Video Conferencing Systems: When Is the Quality Worth the Cost?
Overview The marketing literature for videoconferencing products often makes recommendations for settings that will yield acceptable subjective video quality; however, these recommendations have not been empirically validated. Additionally, a number of high bandwidth conferencing systems have been created that promise high video quality, but with extremely high bandwidth costs. An experiment was conducted investigating the subjective perception of video quality under the following conditions: 384 kbps, 1920 kbps, DVTS, and plain video. Four test scenes were used that differed in the amount and type of motion present in the video. Participants viewed sequences of reference and test scenes on a Samsung 42-inch plasma display, and made subjective ratings of all scenes using a discrete, 5-point scale.
