Abstract
Systems and methods of decoding data streams and conserving power are described. In some embodiments, a stream of data containing audio and other data is divided into a plurality of timeslots. A first timeslot of the plurality of timeslots is allocated to a first service. A grant allocation message which indicates a location of the first timeslot allocated to the first service is generated. The grant allocation message and the plurality of timeslots are transmitted to a receiver. The transmission system and receiver may be compatible with NRSC-5. The receiver may receive and decode the grant allocation message to identify OFDM symbols that carry information regarding the first service. The receiver may also receive the plurality of timeslots. The receiver may set a power mode of a component during OFDM symbols that indicate a status of the first service.
