METHOD, DEVICE AND SYSTEM FOR MULTIPOINT VIDEO COMMUNICATIONS

摘要

A method, device and system for multipoint video communications are disclosed in the present invention. The method comprises: determining whether there are image-capture objects in an image capture area during the current period; if there are no image-capture objects in the image capture area during the current period, not reporting image information in the image-capture area during the current period to a multipoint control unit. The method, device and system for multipoint video communications disclosed in the present invention enable the images corresponding to the image information reported to the multipoint control unit to comprise the image-capture objects at all time, therefore avoiding the problem of system resource waste for the reason that there are no image-capture objects in the images corresponding to the image information reported to the multipoint control unit, saving the system resources, decreasing the load of the multipoint control unit, and improving the overall performance of the multipoint video communication system.
