The present invention provides a software architecture for managing applications in a television set-top terminal. The API (Application Programming Interface) provides a mechanism based on ITU-T X.731 for monitoring and controlling applications. An application program such as a program guide, a stock ticker, and the like is recovered from the terminal according to the related position setter. The application program is registered 205 and installed in the terminal, and after the registration, the user is notified of the existence of the application program. The API 270 enables execution, stop, resume, and stop of the application program. The API also allows an application to change each of their states, such as an alarm state 325, an availability state 330, a processing state 335, an operational state 310, a managed state 305 and a usage state 315, To notify the application program.
