ARRANGEMENT AND METHOD FOR GENERATING CONTINUOUS PRESENCE IMAGES

摘要

The present invention relates to generating Continuous Presence (CP) images in a Multipoint Control Unit (MCU) managing a multisite videoconference. The invention utilises the bit structure of the ITU H.26* standards to reduce the processing time and requirements in an MCU for generating CP views without self-view. By rearranging macroblocks from coded CP images, regions in a CP image may be removed so as allow transmitting CP images without self view to the participating sites. The rearranging procedure significantly reduces the requirement of encoder resources in an MCU.
