Abstract:
1. A receiver suitable for accessing selected portions of synchronized data transmitted by a broadcaster in a broadcasting system, the receiver comprising: a synchronized data accessing system capable of providing an application program with access to synchronized data transmitted by the broadcaster in the broadcasting system, the synchronized data accessing system including an application programming interface which can be used by the application program as an interface to the synchronized data accessing system, wherein the application programming interface can also be used by the application program to initiate a listener provided by the application programming interface as a listener interface for accessing a selected portion of synchronized data transmitted by the broadcaster and, wherein the application subsequently waits for a notification that notifies the application program that the selected portion of synchronized data is available and can be accessed by the application program after initiating the listener, wherein the listener determines whether the selected portion of synchronized data is available for access and notifies the application program that the selected portion of synchronized data can be accessed at a point of access which can be linked to the listener when the listener determines that the selected portion of synchronized data is available and can be accessed, thereby allowing the application program to access the selected portion of synchronized data at the point of access when it becomes available without having to monitor the data transmitted by the broadcaster for broadcast of the selected portion of synchronized data.
