METHOD OF PROCESSING A VIDEO STREAM IN A MULTIMEDIA BOARD FOR A MULTIPOINT DESKTOP VIDEO CONFERENCING

摘要

The present invention relates to a method for processing a video stream in a multimedia board for multi-party desktop video conferencing. The present invention relates to a method for processing a video stream in a multimedia board in which a video stream processor is dualized in a video stream compression / restore unit. Initializes each hardware component in the multimedia board, loads the microcode required to perform compression / restore of the video stream compression / restoration to the processors 1 and 2, and sets the necessary parameters for video compression / restore to drive the processor. Making a first process; A second process of the processor 1 performing a compression process to compress the video stream according to the driving of the processor 1 of the first process; A third step of performing the reconstruction processing by the processor 2 to reconstruct the video stream according to the driving of the processor 2 of the first step; The processor 1 and 2 perform a process of compressing and reconstructing each of the processors through mode conversion for multi-view video and video processing. It is possible to improve the quality of multi-party desktop video conferencing by compressing one video stream inputted by a video signal and simultaneously converting and compressing a compressed video stream received through a communication network according to a two- or three-party conference.
