RESUMO

The terrestrial digital television systems have been established and expanded by the worldwide. It is expected that 1.4 billion analog TV sets will be replaced by set-topboxes and digital receivers TV sets, also known as access terminals. This fact shows the relevance of these devices that receive and decode the digital signals. Given the diversity of the hardware platforms of different manufacturers and different set-topboxes profiles, there is a need for a major investment to create and develop applications and Middleware because for each hardware platform, different source codes need to be developed. Beside the fragmentation of implementations resulted by the diversity of hardware platforms, there is an increasing demand for performance and solutions with more functions. To address these questions, there are organizations, initiatives and emerging technologies, some of them based on software components, that are consolidating techniques that can be applied to the software stack of a set-top-box, from among we emphasize the UHAPI, M3W, IOS and GStreamer. This master thesis deals a comparative analysis of these technologies and presents a set-top-box software architecture proposal called Arquimedia. Performance tests were made and analyzed to validate the proposal.
