Remark:

Since the winter term 2021 due to the SARS-Cov-2 pandemic still is a very special one, we have decided to offer the course Multimedia Transport in a format considering the possibility for as well students as lecturer and tutors to give and / or consume parts of the course online using web-conference tools:

  • Course material, quizzes and assignments will be done in Moodle.
  • Lectures will be offered in Teams, potentially in a hybrid fashion (lecture hall plus Teams).
  • The content will be based on our MT-book that is available in various formats (ipynb, pdf, html).

Course Details

Introduction

Nowadays a significant portion of the Internet traffic is due to audio/visual applications (VoIP, Youtube, IPTV). However, the used transport protocols (TCP, UDP/RTP) are inappropriate and lack means of optimized and application layer adapted content transport.

The course will introduce the requirements for media transport in the Internet, introduce proper channel models, calculate the channel capacity of those channels and derive a framework for optimized media transport. The focus is on the error coding in the transport layer, so that the results can be applied to any audio/visual application.

Besides giving an overview over recent specifications and standards (DVB, DASH, QUIC) the course will introduce latest research results on media transport.

Prerequisites

Digital Transmission & Signal Processing as well as Audio/visual Communications and Networks are recommended for this course. Students with solid background in Computer Networks and Error Correction, however, are also encouraged to participate.
