Qualification goals of the lecture

  • We focus on auditory and visual media
  • We learn how to understand and evaluate methods for the digital acquisition, processing, storage, and transmission of multimedia data
  • We create content for modern communication media
  • We improve our ability to design and evaluate media
  • We formulate and solve problems using practical examples

Course Structure

  1. Introduction and Organization
  2. Fundamentals and Applications
  3. Introduction to digital signal processing
  4. Digitization of audio, images, and video
  5. Audio effects
  6. Image processing
  7. Compression of images, audio, and video

Lecture

Exercise Class

  • Exercise class (2h per week)
  • Assignments are handed out, which are prepared and followed up in the exercise class (every 1 or 2 weeks)
  • Mondays after the lecture, HS III
  • Structure of assignments:
    • Short film / interactive project (in groups of 1 to 4 students)
    • Practical and theoretical questions (everybody individually)
  • The assignments are made available every Friday around 12h00 on ILIAS

  • Admission requirements for the exam:
    • Submission of the finished short film (or interactive project) at the end of the semester
    • Passed 5 out of 7 assignments (passed means ≥ 50%)
    • Important: These rules are strictly enforced

Exam

  • Oral exams

  • Difficulty of questions is similar to the ones known from the assignments

Exam

  • Registration for the exam takes place from mid-May to around the end of June (exact dates here) via Marvin
  • The oral exams will take place from July 15 to 29, 2024 (the exact dates will be subject to our discussion)
  • The grade for the lecture only depends on the grade in the final examination (i.e., the assignment points are only used for the admission to the exam)
  • 9 ECTS points for passing the exam

Film project

  • Film project: short film of maximum 5 minutes:
    • Development of the idea
    • Find a concept for realization and subsequent usage
    • Planning using script and storyboard
    • Recording the raw footage
    • Film editing and post-processing
    • Incorporate the video in a public or internal website
  • If you publish films with third party content, make sure that you respect the copyrights (this is your personal responsibility)

Film project
