| Popis: | 88 The study focuses on the solution of “Video Telephony Service” over Internet to solve the limitation of Telephony Service with VoIP technology based on H.323 standard under current environment, and considers the complex of system affiliated with Video Communication application. Presently, academic community had done lots of researches in H.323 protocol regarding QoS Control, Rate control, and Error control; however, it seldom concentrated on the current network environment, the structure limitation, user habit and system integration. Now it proposes a new structure based on H.323 and should review precisely the information exchange procedure including control message and multi-media data. It also redesigns a switching system for “Video Telephony Service” which is an application oriented switching system and could be constructed at every service node. This is just like the concept of “Active Switching”. It analyses each document of protocols under H.323 Protocol Stack and a serial of technique papers which is published in Vol.15, No. 6, Aug. 1997, IEEE JSAV journal and studies related topics of Rate Control, CODEC Design, Synchronization Control, and Admission Control. It also investigates and integrates current networking environment (Ex. Ethernet, TCP/IP), PBX Interface, CTI Planning, Hub/Switch Design, Video Capture Card Application, and Windows Programming. |
