"SOFTWARE APPLICATION AND MANAGEMENT LIFE CYCLE FOR TRANSMISSION APPLICATIONS". It is a software architecture for managing application on a subscriber-type television terminal. An application programming interface (API) provides an ITU-T X.731-based mechanism for monitoring and controlling applications, applications such as a program guide, stock ticket or the like are covered in the terminal according to a associate landlord. Registered applications (205) are installed in the terminal, and a user is notified of the presence of applications after their registration. API (270) allows application execution, pause, continuation and stopping. The API also allows applications to announce their respective states to other applications, such as alarm states (325), availability state (330), procedure states (335), operability state (310), administrative states (305) and states of use (315).
