FEKT-BPC-MDSAcad. year: 2019/2020
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.
Learning outcomes of the course unit
Students will obtain theoretical foundations of multimedia services in IP networks. Based on these foundations, students will be able to analyze and design multimedia systems. Students will be able to explain principles of real-time multimedia data distribution, principles of servises such internet television, videoconference, internet television and streaming. Student will know audio and video codecs used for audio/video compression.
Basic knowledge of IP networks is required.

Planned learning activities and teaching methods
Teaching methods include lectures and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Students have to write a single project/assignment during the course.
Assesment methods and criteria linked to learning outcomes
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.
