Educational goals

The main objective of the course is to cover the theoretical background that is essential for the understanding of the technologies, architectures and challenges of Multimedia with emphasis on the transmission of multimedia information. By the successful completion of the course the student should be able to:

  • Describe and define the characteristics of the media as well as the multimedia and systems.
  • Describe the particular characteristics, standards and technologies that are related with the various media.
  • Distinguish the particular characteristics of the media such as sound, image, video and the analog/digital TV.
  • Explain the basic coding media techniques.
  • Define and describe the network demands of the multimedia as well as of the technologies for the transmission of multimedia information through Internet.
  • Explain the issues related with quality or service and quality of experience as well as with the mechanisms for the transmission of multimedia with guaranteed quality.
General Skills
  • Search, analysis and synthesis of information by using the appropriate means and technology
  • Independent and cooperative work
  • Criticism and self-criticism ability
  • Promote of free, creative and inductive thinking

Α. Semester Project (SP) (50%)
- The project requires the investigation and study of up-to-date and reliable related research literature. The deliverables are a written essay of 2500-3000 words and a public presentation of 20 minutes duration.
- The topics, specifications and evaluation criteria of the project are announced after the second teaching week.

Β. Final written examination (FΕ) (50%)
- Multiple choice questions
- True/false questions
- Questions that require short answers

The final score of the course (SP*0.5+ FΕ*0.5) should be at least five (5). Moreover, both SP and FE individual scores should be at least five (5).

The evaluation criteria are listed in the course’s webpage in the learning platform (Moodle) and are explained to the students in the classroom.
