An Architecture based on Ontologies, Agents and Metaheuristics Applied to the Multimedia Service of the Brazilian Digital Television System

With the advent of the Brazilian Digital Television System, that arrives on approximately 95% of Brazilian homes, the users will be able to have an interactive channel by the utilization of the digital television. Thus, will be possible to access the multimedia application server, i.e., to send or to receive emails, to access interactive applications, to watch movies or specific news. This paper proposes the development and the implementation of an architecture that includes a module that suggests the content to the user according to his profile and another module to optimize the content that will be transmitted. The implementation was developed using ontologies, software agents, Tabu Search and Genetic Algorithm. The validations of the results are done using a metric.
