The aim of the Multimedia Laboratory (426, C2 building ) is to
educate and perform research on transmission, storage and delivery of
multimedia information and services. The infrastructure gathered in the
laboratory makes it possible to demonstrate how to organize teleconference
systems and multimedia data servers. These systems can be accomplished
in IP networks as well as experimental environments built over ATM system.
Video on Demand service and integration of digital and analog television
with a computer network can also be investigated in our laboratory.
