<P>PROBLEM TO BE SOLVED: To provide techniques for region-of-interest (ROI) processing for video telephone (VT) applications. <P>SOLUTION: A recipient device defines ROI information for video information transmitted by a sender device, i.e., far-end video information. The recipient device transmits the ROI information to the sender device. Using the ROI information transmitted by the recipient device, the sender device applies preferential encoding to a ROI within a video scene. In this manner, the recipient device is able to remotely control ROI encoding of far-end video information by the sender device. <P>COPYRIGHT: (C)2012,JPO&INPIT |
