REDUCED BANDWIDTH VIDEO TRANSMISSION |
摘要 |
A bandwidth reduced teleconferencing system achieving good video presence. The bandwidth reduction is accomplished by dividing the video picture of the camera into segments, by determining the activity level within each segment and by transmitting the signal of each segment with a resolution level which is related to the activity level within the segment. The most active segment is transmitted at highest resolution while other segments are transmitted at lower resolutions. |
