Abstract

Given that broadcasting is generally characterized by real-time one-way transmission, it is an essential task for this medium to provide interactivity developed in the fields of telecommunications and computers when introducing multimedia into a broadcasting system. This paper discusses how to use and implement interactivity in broadcasting services. It further discusses what functions are required for introducing interactivity into broadcasting. The practicality of interactive services in one-way broadcasting transmission is clarified. A simulation system of ISDB services to evaluate viewers´ human interface was developed. The results of experiments using the simulation system are also discussed. It is shown that user-friendly ISDB services can be achieved
