Resumo

The recent publication of the middleware standards for the Brazilian digital terrestrial TV system has caused a growing interest in iTV based services. This fact, together with the familiarity of the Brazilian population in operating legacy analog TV sets (present in 98% of the households) and the very low availability of Internet (present in 24% of the households), has motivated researches on platform independent iTV services that could contribute to overcome the digital divide in Brazil. These are the main topics of the SMTVI (Multiplatform Services for Digital Interactive TV) project, sponsored by Brazilian Ministry of Communications R&D Program (FUNTTEL). In this paper, we describe the conception and the specification of t-CoD, an iTV content on-demand service. The work is substantiated by demand analysis of Brazilian Internet-based services and on surveys in countries which deployed similar services. The functional requirements for two t-CoD applications and a business model for the deployment of commercial t-CoD services are also presented.
