ABSTRACT:
A computing system such as a Programmable Video Recorder (PVR) receives broadcast data and enhanced file-state data from a data source. The broadcast data may include multimedia data. The enhanced file-state data may include web-based data such as ATVEF data. The PVR buffers the broadcast data and the enhanced file-state data in a backing store that is associated with the PVR. The PVR also creates an index for indexing the enhanced file-state data so that, when the broadcast data is rendered, the correct file-state data can be located and rendered at the appropriate time with the broadcast data. The index may classify the enhanced file-state data by GUID, sequence number, and valid start and end times associated with corresponding broadcast data. The index may also include pointers for locating the enhanced file-state data from the buffer of the PVR.
