It comprises central server means with at least one central cache arrangement for storing at least selected parts of data information relevant for at least a segment of the wireless network, transmission scheduling means for transmission scheduling, central cache arrangement control means for, by using scheduling information, controlling a central cache arrangement push engine for multicast/broadcast pushing of information to end user stations within said at least one segment of the wireless network.

Abstract: A full multimedia production such as a seminar, conference, lecture, etc. can be captured in real time using multiple cameras. A live movie of a speaker together with the speaker's flipping still images or slide show can be viewed interactively within the same video display screen. The complete production can be stored on a hard drive for retrieval on demand, or sent live to a host server for live distribution throughout a data network. It is also possible to store the complete presentation on portable storage media and/or to send the complete presentation as an e-mail.
