Abstract

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 it 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.
