Time-lined hypermedia for digital interactive broadcasting and its practical implementation

Digital broadcasting services have developed rapidly and are spreading all over the world. Digital broadcasting is one of the most promising infrastructures to provide interactive services aimed for consumers. However, the broadcast bandwidth has an upper bound limitation. This paper describes our proposition, a hypermedia model, called time-dependent hypermedia, which is designed to provide a larger hypermedia navigation space in a limited broadcast bandwidth. We also describe a practical implementation of time-dependent hypermedia for digital data broadcasting services
