碩士 === 國立成功大學 === 電機工程學系碩博士班 === 91 === Due to the development of technology of Internet, more and more requirements of the application tools, such as “Video Conference”, are needed. Before, image is transferred to other users by software applications in computers or workstations over internet. With the development of network protocols and data compress algorithm, the performance of Video Conference would become better and better. However, using only software to complete all operations in the Video Conference on computers or workstation would make much overhead to center processor. Moreover, the number of participants and the performance of image quality would be limited. Therefore, implementing the whole system to hardware would be a nice solution to increasing participants and enhancing image performance without overhead of computers and workstations. In several network protocols used by Video Conference System, real-time transfer protocol(RTP) is one which is usually used in real-time application. The specific packet format, transmission control mechanism, and lower protocol of RTP can make application to transmit media stream in real-time. The real-time control protocol(RTCP) in RTP can determine the transmit frequency of RTP packet by time stamp and sequence number in the RTP packet header. Using RTP is a nice beginning to implement the Video Conference System. In this thesis, we focus on the RTCP packet and propose the hardware architecture of RTCP packet processor and generator. In addition, we will point out our future work of implementing whole Video Conference System in the end of this thesis.
