A software architecture for managing applications at a television set-top terminal. An Application Programming Interface (API) provides an ITU-T X.731- based mechanism for monitoring and controlling the applications. Applications, such as a grogram guide, stock ticker or the like, are recovered at the terminal according to an associated locator. The applications are registered (205) and installed at the terminal, and a user is notified of the presence of the applications after registration thereof. The API (270) enables running, pausing, resuming and stopping of the applications. The API also enables the applications to advertise their respective states to other applications, such as alarm statuses (325), availability statuses (330), procedural statuses (335), operational states (310), administrative states (305), and usage states (315).

L'invention concerne une architecture de logiciel, permettant de gérer des applications au niveau d'un boîtier de raccordement de télévision. Une interface applicative (API) fournit un mécanisme basé sur la norme ITU-T X.731, permettant de contrôler et de commander les applications. Des applications, telles qu'un guide de programmes télévisés, un service d'informations boursières ou analogue, sont récupérées au niveau du terminal en fonction d'un dispositif de repérage associé. Les applications sont enregistrées (205) et installées au niveau du terminal, et un utilisateur est informé de la présence de ces applications après leur enregistrement. L'API (270) permet d'exécuter, de marquer une pause, de reprendre et d'arrêter les applications. L'API permet également aux applications d'avertir d'autres applications, de leur état respectif, tel qu'un état d'alarme (325), un état de disponibilité (330, un état de procédure (335), un état de fonctionnement (305), et un état d'utilisation (315).
