OpenTV is the system software and API used in the Swedish digital terrestrial network for developing the kind of new data services that are enabled through digital television. The European co-operation organisation, Digital Video Broadcasting (DVB) is developing an open specification for a new platform called the Multimedia Home Platform (MHP). The MHP includes an API (the DVB-J API) which is based on the JavaTM programming language. With the DVB-J API, conditions are created for making the digital-TV market horizontal. By the time the DVB-MHP specification is published, implemented and verified in the target environment, a migration from OpenTV towards DVB-MHP is expected. This master thesis investigates how the migration might have an impact on services, applications and the head- end architecture. Mainly focus is put on investigating how to convert OpenTV applications to DVB-J applications. A verified migration model for easy manual migration of OpenTV applications to DVB-J applications is proposed. The migration model contains a migration framework and concentrates on migration of common elements and features inherent in most digital television applications. A developer customises the migration framework to a particular application by sub-classing and composing instances of framework classes. The conclusion is that ...
