Multiple-picture out method and system

Abstract

The present invention provides a multiple-picture output method and system. In n-point communication environment, a multiple-picture supporting module is configured to extract image data of n points from MCU and transmit them to multiple-picture server. The multiple-picture server converts the received image data into analog video signals and outputs the signals. In multipoint communication, the present invention makes it possible for any communication point to watch the images of other communication points in real time. That is, the main communication point can watch the images of all or parts of sub-communication points at the same time, while a sub-communication point can watch the images of the main communication point and all or parts of other sub-communication points at the same time. The method and system of the present invention can display a plurality of image information on a plurality of display equipments while the image resolution is high, the image display is smooth and the system compatibility is strong.
