Network multimedia systems


Aim of the course

Acquiring knowledge, competence and practical skills in the field of multimedia stream representation, generation and storage as well as the methods of effective multimedia distribution in contemporary computer networks.

Lecture programme

Digital image and sound representation, methods of encoding. Description of multimedia sessions. Protocols of multimedia data transmission. Usability analysis of various transport protocols for multimedia data distribution. Adaptability of multimedia streams size. Signaling protocols used in the multimedia session organization (RTSP, SIP, H.323). Architecture of the MPEG-4 standard. VoIP technology and standards used in it. Group communication and multicast routing in the IP networks. Quality of Service issues in the IP networks (DiffServ and IntServ architectures).

Overview of the course elements

The course comprises laboratory classes which provide practical training on topics discussed during the lectures. Classes are run in a dedicated laboratory equipped with modern image and sound encoding apparatus allowing real time processing and presentation. Variety of signal sources is used, including analog and digital ones as well as DVB-T and DVB-S ones. Laboratory is equipped with advanced network devices used to establish network configurations for multimedia data transmission, IP telephony and to apply Quality of Service policies and multicast routing.
