Objectives and competences:

The objective of the course on Multimedia technology base is to familiarize students with fundamental of phisics and basic technologies of (electrotechnical) engineering wihch multimedia relies on. The subject is a basis for understanding professional courses and practical work in forthcoming semesters of multimedia studies.

The course deals with the systematic and electrical engineering technology base on which multimedia is based. Awareness and use of material is reinforced with a pronounced shift from practical experiments to the physical phenomenon. The goal is to get a deeper knowledge of high school physics with an emphasis on events that are facing media technologist. The course develops science-oriented analytical-synthetic thinking. Students learn about the basics of electrtechnics, sound waves and electromagnetic waves (radio and optics) with an emphasis on treatment and understanding of communication and multimedia systems. The course also shows the physical and technological limitations of broadcasting systems from the standpoint of radio wave propagation and noise. In the lab students are introduced to basic methods of measuring physical quantities. The subject is the basis for practical work and understanding of technical subjects in higher levels of the study program.

Intended learning outcomes:

After successful completion of the course, students should be able to:

  • classify the physic phenomena which are Multimedia technology base,
  • explain the basic laws in the field of (electrical) engineering,
  • measure basic physical quantities from the field of electrotehnics, sound, optics and radio,
  • explain clearly the technological capabilities of modern multimedia devices,
  • select the most appropriate transmission media for multimedia services based on the capabilities of the communication link,
  • evaluate the physical limitations of future multimedia devices,
  • calculate the technological parameters of multimedia devices.

Learning and teaching methods:

  • Lectures, laboratory work, homeworks and seminars, IT assisted learning.
