Timeslot scheduling in digital audio and hybrid audio radio systems
First Claim
1. A method comprising:
- dividing a stream of data into a plurality of timeslots;
allocating a first timeslot of the plurality of timeslots to a first service;
generating a grant allocation message that indicates a location of the first timeslot allocated to the first service;
transmitting the grant allocation message to a receiver; and
transmitting the plurality of timeslots to the receiver,wherein the receiver selectively deactivates unused components of the receiver based at least in part on one or more of the plurality of timeslots.

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 location 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 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.

16. A receiver comprising:
-
a tuner configured to receive a grant allocation message and a plurality of timeslots; and digital signal processing hardware configured to decode the grant allocation message to identify OFDM symbols that carry information regarding a first service, set a power mode of a component of the tuner during OFDM symbols that indicate a status of the first service, and send power control signals to at least one component of the tuner, one or more analog to digital converters (ADCs), and digital hardware. - View Dependent Claims (17, 18, 19)
