FEKT-CMDSAcad. year: 2017/2018
The course Multimedia Services is divided into three parts. The first part is focused on the network technologies and multimedia data transmission over Internet network. Concretely, the routing in IP networks, the muticast 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 have the special attention. The detail description of today's videoconferencing and voice over IP technologies are introduced in the second part of the course. The teaching is focused on 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

Language of instruction
2. Multimedia data transmission in packet networks - I (ISO-OSI vs. TCP/IP, TCP-IP model - link layer, network layer - routing).
3. Multimedia data transmission in packet networks - II (TCP-IP model - network layer - multicast, quality of services QoS (Intserv, Diffserv)).
4. Multimedia data transmission in packet networks - III (TCP-IP model - transport layer - TCP/UDP protocols, application layer - RTP, RTSP, RTCP, SDP, SAP protocols).
5. Real-time audio/video communication I - (Videoconferencing, basic concept, H.323 standard).
6. Real-time audio/video communication II - (VoIP, SIP protocol - architecture, basic communication model).
7. Real-time audio/video communication III - (SIP protocol - advanced methods.
8. Bitmap image compression (bitmap image properties, Human visual system, JPEG, JPEG 2000 image compression standards).
9. Video compression I - (MPEG standards).
10. Video compression II - (Audio/video transmission methods described in MPEG - standards, program vs. Transport stream, DVB, MHP - interactive services in MHP).
11. Video compression III - (H.26x standards).
12. Voice and audio compression - (G.7xx, CELP codecs, MPEG-1 audio codec).
The objective of this subject is to provide practical skills and fundamental theoretical knowledge about multimedia communication services operating in computer and telephony networks.
