MPEG4 VIDEO CONFERENCE SYSTEM CONTROLL PROCESSOR BASED ON INTERNET PROTOCOL NETWORK

摘要

PURPOSE: An MPEG4 based image conference control system and method on IP network are provided to be capable of being correlated with an H.323 terminal as well as implementing image conference on an IP network using MPEG4 technique. CONSTITUTION: A connection manager interface(301) is connected to an upper DMIF(Delivery Multimedia Integration Framework)(203). A synchronizing device(302) synchronizes input signals for service request from the DMIF(203) and identification request from a lower layer(H.245)(Q.931). A status manager device(303) performs the status control and service control related to call and access processing for the MPEG4 image conference. A message analysis and service distributor(304) performs the analysis for the synchronized and ordered service input and the service distribution through status management. A control signal converter(305) converts signals input through the interface(301) into service request parameters of signals corresponding to H.245, Q.931. A connection manager information/resource management device(306) performs the management of network resource for control signal channels together the call connection(Q.931) and the control signal(H.245) connection management.
