Transmission of hypertextual information using MPEG-2 private data

2 IBM Semea S.p.A., via Mameli, 09123 Cagliari ItalyABSTRACTIn this paper, we design a new system for the transmission of multimedia information within the digital TV channelin a broadcast fashion. The scheme proposed is based on some DSM-CC functions, studying an additional syntax thatallows to convey all the data required to manage with the multimedia information at the reception side. The transportstructure used is the well-known MPEG-2 Transport Stream, that is the most widespread platform for new digitaltelevision systems. The multimedia information conveyed in such a model is similar to that of the WWW system, that isan hypertextual file system where the text is integrated with images, sounds and animation. A proper encoding softwarehas been realised, that codes the file system by means ofthe DSM-CC operations and brings out a Trasport Stream.KEYWORDS: MPEG-2, digital TV, DSC-CC, data broadcasting, multimedia, hypertext, world-wide-web.
