Abstract
    First open universities were established in 1970s, and these were, among others - the Open University (United Kingdom) and Fernuniversitaet (West Germany). In the era of information society, educational systems have been evolving continuously owing to the development of the Internet, digital communication, computer techniques, satellite television and multimedia techniques.
    Didactics supported by multimedia involves the use of various technical tools and multimedia techniques based on the Internet for educational purposes.
    The first part of the thesis presents characteristic features of didactics for the university of technology, which is to be supported by Internet multimedia. Subsequently, technical mechanisms are presented, followed by the empirical part, where Internet multimedia functions are elaborated upon, with special consideration for streaming multimedia files. The present thesis provides examples of open education systems, where Internet multimedia are successfully employed. More attention was given to a series of hyper-media lectures "Selected legal issues" held by dr hab. Tadeusz Lemańczyk at the Poznań University of Technology.
    The present thesis also includes an analysis of the technical potential of the Lecture Center of the Poznań University of Technology, which can be used for supporting didactics with Internet multimedia, as well as for developing and providing multimedia materials for the open education portal, similar to the examples that have been put under analysis in the present thesis.
