摘要
A method and apparatus for displaying a user selected region-of-interest clearly on a video display terminal in an audiovisual conferencing system is disclosed. The method comprising the steps of having a user select his or her region-of-interest on a display terminal with an input device, having the video decoder translate the user's selection to corresponding horizontal and vertical coordinates recognizable both by the video decoder and the video encoder, having the video decoder transmit the coordinates to the video encoder through a back transmission channel, and having the video encoder allocate bits originally for representing compressed video information outside the region-of-interest to represent compressed video information within the interested region of images and transmit the compressed video information to the video decoder through a forward transmission channel.
