Course detail

Multimedia Services

FEKT-BPC-MDSAcad. year: 2018/2019

Multimedia Services course is divided into three parts. The first part is focused on network technologies and multimedia data transmission over the Internet network. Concretely, routing in IP networks, the multicast technology and quality of services will be introduced. The application layer protocols of TCP/IP model that are used for multimedia data distribution and control will receive special attention. A detailed description of today's videoconferencing and voice over IP technologies will be introduced in the second part of the course. The teaching is focused on the H.323 and SIP standards. The last part of the course is about compression algorithms for image, video and audio data. Mainly, the JPEG, H.26x, MPEG-x and G.7xx compression standards will be described.
