Abstract: A method and apparatus facilitate control of interactive application execution through use of defined time periods. A broadcaster (110) transmits a broadcast program, an associated interactive application (170), and at least one definition of a time period from a set including: a first time period, during which execution of the application may be offered to a viewer; a second time period, during which execution of the application may be started; and a third time period, during which the application may be executed. A viewer tunes to a channel associated with the broadcast program and interactive application. A broadcast receiver (140) offers the viewer the option to execute the interactive application (170), if within the first defined time period. If the user elects to so execute, the broadcast receiver starts said execution, if within the second defined time period. If the interactive application continues to execute at the end of the third defined time period, the broadcast receiver retires the interactive application.

Abstract: A method and apparatus facilitate the retirement of interactive applications in a manner associated with an external event and a program state of the interactive application. A broadcaster transmits an interactive application that includes a plurality of retirement instructions associated with external events and internal program states of the interactive application. A broadcast receiver receives an interactive application, stores the included retirement instructions, and executes the interactive application concurrently with the display of an associated television program. The broadcast receiver monitors the broadcast signal for events indicating that the executing interactive application is no longer appropriate for the current television program. Upon detection of such an event, the broadcast receiver retrieves the stored instructions, and retires the interactive application in a manner appropriate for both the detected external event and the internal program state of the interactive application, according to the stored instructions.
