DATA BROADCAST METHOD
First Claim
1. A system for providing requested data sets of broadcast data service transmitted as part of a broadcast signal, comprising:
- a broadcast headend configured to receive a data request from a receiver, and configured to broadcast requested data sets to the receiver in response to the data request from the receiver;
a processor configured to periodically extract all of the requested data sets of the broadcast data service from a broadcast carousel included in the broadcast signal;
a memory configured to store all of the requested data sets of the broadcast data service, the requested data sets containing digital audio/video data and defining a plurality of digital audio/video data sets, the digital audio/video data sets including television clips;
a first controller configured to allow selection from a list of the plurality of sets of the digital audio/video data sets; and
a second controller responsive to a user initiated selection signal to cause the memory to output a user selected one of the plurality of digital audio/video data sets selected from the list, the selected one of the plurality of digital audio/video data sets having digital audio/video data in non-real time,wherein the processor converts the digital audio/video data of the requested data sets of the broadcast data service into real time audio/video data.
