摘要： A system and method implemented in an interactive television system for managing modules of interactive television applications. The system transmits modules from a broadcast station to a plurality of receiving stations through various paths, such as broadcast channels and modem channels. The receiving stations have module managers which store module requests and which monitor the various channels for modules corresponding to the requests. When modules are transmitted on the monitored channels, they are matched with the corresponding stored requests. If a module matches one of the requests, or if is an auto-loading module, it is stored in the receiving station. If a module has not been requested and is not an auto-loading module, it is ignored. The stored modules are added to a list of modules available for execution or for use by an executing application, and the corresponding requests are deleted.

摘要： A system and method implemented in an interactive television system for restricting or controlling the access rights of interactive television applications and carousels. The system broadcasts modules from a broadcast station to a plurality of receiving stations, which execute applications containing the modules. In one embodiment, the applications utilize a credential consisting of a producer identification number (ID) and an application ID for each of the grantor and grantee applications, an expiration date, a set of permission data, a producer certificate and a signature. An application requesting access and a carousel granting access may be identified by respective producer and application IDs. The credential utilizes public key encryption to ensure the integrity of the credential. The producer and application IDs may be replaced with wildcards so that rights may be granted to a group of producers or applications.
