TITLE: Multimedia Communications

MODULE SUMMARY (INDICATIVE):
The module mainly focuses on providing key concepts about multimedia signals
(audio, images and video) and relevant compression and transmission techniques.

AIMS:
To provide students with:

  • An understanding of Quality of Service (QoS) parameters and mechanism
    applied to IP networks.
  • An understanding of the principles of source coding applied to voice, audio,
    image and video compression.
  • Experience of managing multimedia data and relevant transmission aspects
    through different software tools.

LEARNING OUTCOMES:
On successful completion of the module the student will be able to:

  • Analyse specific source coding techniques for multimedia sources and
    relevant transmission aspects
  • Specify the QoS support required by different multimedia sources.
  • Apply the learned concepts in a laboratory environment.
