This course covers multimedia networking protocols, where basic techniques are studied to design, configure and operate networks and multimedia services. The program is divided into four parts: PART I: Audiovisual services and distributed multimedia applications, Network requirements and protocol architectures. PART II. Multicast routing service. Case study: IP television in telecommunication operator networks. PART III. Multimedia transport protocols over packet networks PART IV. QoS architectures in packet networks. PART V. Services based on multimedia streaming. Case studies: video-on-demand services in the Internet (Netflix and YouTube). PART VI. Signaling of multimedia services over packet networks. IP telephony services.

The teaching methodology will include: 1) Theoretical lectures, which will include the main knowledge that students must acquire. Discussions and resolution of doubts about the concepts acquired by the student in the self-learning process. Review activities. To facilitate its development students will have basic reference texts, enabling them to delve into the various topics covered by the course. 2) Laboratory classes, where students will cooperate in working groups of two or more persons to engage in practices designed to apply, consolidate and deepen into the various theoretical knowledge thought during lecture sessions. 3) Resolution of exercises by the student that will serve to assess their knowledge and acquire the necessary competences. 4) Classes of practical exercises, to address a joint correction of the proposed exercises, which should serve to consolidate knowledge and develop the ability to analyze and communicate the relevant information to solve problems.
