It is a fact, that more and more applications make use of networks. One of those applications will be digital interactive television, relying on a generic protocol solution to provide broadcasting and interaction over network dependent protocols. A digital television transmission, based on a MPEG2 transport stream consists of multiplexed video, audio and Service Information (SI) streams. Service information is important for describing the content of a transport stream and encapsulating various protocols. Because plenty of research work is done on pure MPEG2 audio and video transmissions, this paper deals with service information transmissions, its mechanisms and network requirements if broadcasted over the Internet only. For this reason a DVB-SI broadcast protocol stack will be introduced. UDP and RTP with its packetization schemes will be evaluated and bandwidth consumptions, boundaries and requirements in a LAN/WAN environment evaluated. Finally a software framework for transmission and decoding SI will be presented.
