Course Information

Intended learning outcomes

Die Teilnehmer/innen/ sollen:

  • die Grundlagen von Multimedia-Kommunikation und Dienstgüte (QoS) in Netzwerken sowie jetzige und mögliche künftige QoS-Unterstützung kennenlernen (insbes. in drahtlosen Netzen und im Internet);
  • sich mit Mechanismen und Protokollen zum Transport und zur Adaption von Echtzeitdaten ("Multimedia") vertraut machen;
  • ggf. im Rahmen eines Projekts praktische Erfahrung zu Multimediadatenübertragung und zu den Konzepten von QoS und Medien-Adaption gewinnen, durch Arbeit mit SW- oder HW-Komponenten, die QoS und Adaption benötigen bzw. unterstützen, oder durch Simulation;
  • sich ggf. auf weiterführende Projekte (z.B. Praxissemester, Diplomarbeit) im Bereich Multimedia vorbereiten.

Course content

Die Lehrveranstaltung behandelt die Grundlagen von Multimedia-Kommunikation und Dienstgüte (Quality of Service, QoS) in Netzwerken (Begriffe, Anforderungen, Parameter, Konzepte, Protokolle) sowie die jetzigen und möglichen künftigen QoS- und Adaptionsmechanismen insbes. in drahtlosen Netzen und im Internet. Die Vorträge zu den Konzepten werden ergänzt um Projekte zu bzw. Experimente mit Softwaresystemen, die QoS benötigen bzw. umsetzen und Medien-Adaption ermöglichen bzw. durchführen.

Themen:                                                    

  • Einführung in Multimedia-Kommunikation, Internet QoS und QoE: Motivation, Terminologie, An-/Herausforderungen, Prinzipien
  • Video-Codierung und Adaption: Überblick, Prinzipien, Adaptionsmöglichkeiten
  • Internet QoS-Mechanismen: Integrated Services (IntServ), Differentiated Services (DiffServ), Multiprotocol Label Switching (MPLS), Traffic Engineering (TE)
  • Protokolle für Echtzeit-Datentransfer, u.a. Real-Time Transport / Control Protocol (RTP/RTCP), Session Initiation Protocol (SIP), verwandte Protokolle
  • Adaptives Medien-Streaming: "Push"-Verfahren
  • Adaptives Medien-Streaming: "Pull"-Verfahren, Dynamic Adaptive Streaming over HTTP (DASH)
  • Aktuelle Trends, Fallstudien/Anwendungen und Projekte zu adaptiver Übertragung multimedialer Daten (A/V-Streaming)                                                    

Prior knowledge expected

Intended learning outcomes

The students will ...

  • ... become familiar with the fundamentals of multimedia communication and quality of service (QoS) in networks (terminology, requirements, parameters, mechanisms, protocols);
  • ... get to know current and potential future QoS support in networks and media adaptation techniques (particularly “in the Internet“ and in wireless networks);
  • ... become familar with mechanisms and protocols for the transfer and adaptation of real-time data (“multimedia“) in networks;
  • ... get some hands-on experience in multimedia communication and adaptation as well as QoS concepts in the course of assignments and/or small-scale projects;
  • ... acquire expertise required for further projects (e.g., practical term, master thesis) in the area of multimedia systems and communication.

Lectures and assignments/projects

Course content

The course covers the fundamentals of multimedia communication and quality of service (QoS) in networks (terminology, requirements, parameters, mechanisms, protocols) as well as current and potential future QoS support and media adaptation techniques, particularly in the Internet and in wireless networks. The lectures on the concepts will be complemented by assignments, small-scale projects and hands-on experiments with software systems that require or implement QoS and/or media adaptation mechanisms.

Topics:                                                        

  • Introduction to Multimedia Communication, Internet QoS and QoE: Motivation, Terminology, Requirements, Principles        
  • Video Coding and Adaptation: Overview, Principles, Adaptation Options
  • Internet QoS Mechanisms: Integrated Services (IntServ), Differentiated Services (DiffServ), Multiprotocol Label Switching (MPLS), Traffic Engineering (TE)
  • Protocols for Real-time Data Transfer, among them Real-Time Transport / Control Protocol (RTP/RTCP), Session Initiation Protocol (SIP), Related Protocols
  • Adaptive Media Streaming: "Push" Approaches
  • Adaptive Media Streaming: "Pull" Approaches, Dynamic Adaptive Streaming over HTTP (DASH)
  • Current Trends, Case Studies, and Projects in Adaptive Multimedia Data Transfer  (A/V-Streaming)
