Design, implementation and verification methodology of H.324 compliant video conferencing system

摘要

Video conferencing over POTS/GSTN introduces exciting and yet unimagined adventures in telecommunication for as Enabling these adventures is the International Telecommunication union Telecommunication Sector (ITU-T) standard H.324 for multimedia conferencing on POTS/GSTN. Since the completion of H.324 standard in March 1996, Intel, Corp, 8x8, Ince, Smith Micro and VDOnet etc. beging to sale their product at the middle of 1997, But unfortunately, none of them dare to claim that their product will work properly with product from another's. In addition, none of them give out their performance in quantity, such as peak frame rate, sustain frame rate, and corresponding SNR, audio delay etc. Considering these situations, the motivation of this paper is to discuss the design, implementation and verification methodology, also discuss the key technologies used in H.324 videophone design.
