AUDIO AND VIDEO DATA COMPRESSION/DECOMPRESSION PROCESSING METHOD AND APPARATUS FOR REMOTE VIDEO-CONFERENCE SYSTEM

摘要

The apparatus for compressing and restoring audio and video data in a remote control video conference system, wherein the apparatus includes an audio compression/restoration processor(10), a video compression processor(20) and a video restoration processor(30), for processing original audio and video data in the compression/restoration by using the international algorithm(H.261); a video processor(40) for managing and controlling an output shape when restored video data is displayed on a monitor of a computer; a FIFO(80) for outputting the compression video data outputted from the video compression processor(20) to a communication network(100) through a PCI bus(140); a communication network interface board(130) for performing an interface between the PCI bus(140) and the communication network(100); and a FIFO controller(70) for controlling an operation of the FIFO(80), the apparatus also comprises a synchronizing controller(90) for performing a synchronization of the compressed audio data and video data by controlling the interface between the audio and video compression/restoration processors(10,20,30) and the communication network(100); and a bus transceiver (50) and a video bus adjuster(60), which are controlled by the synchronization controller(90) and manage and control the address bus of the video compression processor(20) and the video restoration processor(30).
