One of the consequences of the digitalization of TV systems is the increased amount of available channels and, as a consequence, the great number of services that can be offered to viewers. Due to the great number of content available, there has been a need for applications responsible for helping viewers to find what they want to watch. These applications are called EPGs (Electronic Program Guides). Most work related with EPG focuses either on the development of recommendation systems or on the design of EPG user interfaces. A recommendation system integrated with an EPG adapts the information to be presented based on the viewer’s preferences. On the other hand, the EPG application is responsible for gathering information and generating the EPG. Usually this EPG application can only be replaced by sporadic updates. Unfortunately, as far as the author knows, there is no work that offers support for application adaptations in real-time, which would make it possible to change algorithms without stopping the EPG presentation. This dissertation discusses the importance of providing real time adaptations and presents an EPG implementation based on the support offered by Ginga-NCL. The application modular architecture provides support to dynamic adaptations through a metaservice responsible for these tasks.
