Course detail

Multimedia Services

FEKT-BPC-MDSAcad. year: 2023/2024

The Multimedia Services course is divided into three parts. The first part focuses on network technologies and the transmission of multimedia data over the Internet. Specifically, students will learn about the basics of routing in IP networks, the ability to broadcast to a group address (MULTICAST), and the basics of Quality of Service (QoS) and Quality of Experience (QoE). Particular attention is focused on the application layer protocols of the TCP/IP model that are used for multimedia data transmission and control. In the second part of the course, students will learn in detail about the current technologies used in video conferencing, Internet telephony, Internet TV and video streaming. The last part of the course focuses on image and audio data compression algorithms. Specifically, it includes a description of the JPEG, H.26x, MPEG-x and G-7xx speech codecs.

Department of Telecommunications (UTKO)

Entry knowledge

Basic knowledge of IP networks and basic knowledge of JAVA are required. 

Rules for evaluation and completion of the course

Up to 30 points can be awarded for work in laboratory exercises (points are obtained for individual tasks and individual project).
Up to 70 points can be earned for the written examination.

The definition of supervised teaching and the manner in which it is carried out is set out in the annually updated decree of the subject guarantor. 

Aims

The aim of the course is to provide students with both practical experience and basic theoretical knowledge of multimedia communication services in current transmission networks. 

 

The student acquires theoretical background in the field of multimedia services operated in IP networks. Based on this knowledge, the student will be able to analyze and design small and large-scale multimedia systems. The student will be able to explain the principles of real-time multimedia data distribution, the principles of services including Internet telephony, video conferencing, Internet TV and streaming. The student will also be familiar with the encoders used to compress audio/video signals.
