3DTV Graduate Course 3DTV Graduate Course

Editor: Haldun M. Ozaktas, Bilkent University, Ankara


A graduate course on 3DTV was prepared as a deliverable of Workpackage 14: Design of a New Graduate Course on Three-Dimensional Television, of the EC FP6 IST NoE: Integrated Three-Dimensional Television--Capture, Transmission and Display.

This effort was coordinated by Haldun M. Ozaktas with contributions by Levent Onural on shaping the outline and content of the course and determining appropriate contributors.

  • Editor's Introduction and Overview  [pdf]
  • Overview of 3DTV Technologies   [pdf]

    The course materials have been used at several institutions.

    The complete course, as designed, has been offered by Levent Onural at Bilkent University, Ankara, Turkey. This served as a full trial run of the course. What was special about this offering was that most of the lectures were given by the actual contributors of each module, who travelled to Ankara for this purpose. Thus the students had the chance to learn the material from leading experts in each area.

    The course was also offered at several other institutions, who custom tailored and selected the material to meet the local needs of their students. In some cases parts of the material were selected and in others the material was embedded into another full course. This demonstrated the strength of the chosen modular approach. Since each module of the course was carefully designed to be self-complete, with their own references, notes, etc., it was easy for instructors to choose those appropriate to the needs of their target audience. Atanas Gotchev offered the course at Tampere University of Technology, Finland and Joern Ostermann at the University of Hannover, Germany. Hakan Ürey and Reha Civanlar made use of the material in two separate courses at Koç University, Istanbul, Turkey.

    The following materials are available for most modules listed below:

    • References and/or course notes
    • Course presentation slides/transparencies
    • Speaker notes and/or references (unless embedded in course presentation)
