Abstract

Systems and methods for providing a low power receiver device using fine grained time division are provided. In one embodiment, the receiver device comprises a tuner, a demodulator configured to demodulate at least one sampled signal, a payload processor configured to process at least one demodulated signal into an output format, and a time division control logic configured to generate a control signal to switch at least one component within the receiver device between modes to conserve power. The at least one component may be switched between an active mode, a standby mode, a power off mode, and a low power mode. In further embodiments, the at least one component may be switched between staggered modes.

Claims

1. A system for power conservation in a receiver device, comprising:

a tuner configured to receive a signal;

a demodulator configured to demodulate at least one sampled signal;

a payload processor configured to process at least one demodulated signal into an output format; and

a time division control logic configured to generate a control signal to switch at least one component within the receiver device between modes to conserve power.

2. The system of claim 1 wherein the modes comprise an active mode.

3. The system of claim 1 wherein the modes comprise a standby mode.

4. The system of claim 1 wherein the modes comprise a power off mode.

5. The system of claim 1 wherein the modes comprise a low power mode.

6. The system of claim 1 wherein the modes comprises a plurality of staggered modes.

7. The system of claim 1 wherein the time division control logic is further configured to determine the at least one component in which to switch modes.

8. The system of claim 1 wherein the time division control logic is programmed to generate the control signal to switch the at least one component within the receiver device between modes to conserve power.

9. The system of claim 1 further comprising circuitry for determine time slots in main service channel data corresponding to data that belongs to a service requested by a user, the time slot information being utilized by the time division control logic to generate the control signal.

10. The system of claim 1 wherein the time division control logic is further configured to power off the at least one component during a guard band time.

11. A method for conserving power in a receiver device, comprising:

receiving a signal;

demodulating at least one sampled signal of the received signal;

processing at least one demodulated signal into an output format; and

generating a control signal to switch at least one component within the receiver device between modes to conserve power.

12. The method of claim 11 wherein the modes comprise an active mode.

13. The method of claim 11 wherein the modes comprise a standby mode.

14. The method of claim 11 wherein the modes comprise a power off mode.

15. The method of claim 11 wherein the modes comprise a low power mode.

16. The method of claim 11 wherein generating the control signal comprises generating a control signal which transitions the at least one component between a plurality of staggered modes.

17. The method of claim 11 further comprising determining the at least one component in which to switch modes.

18. The method of claim 11 further comprising programming a time division control logic to generating the control signal to switch the at least one component within the receiver device between modes to conserve power

19. The method of claim 11 further comprising determining time slots in main service channel data corresponding to data that belongs to a service requested by a user, the time slot information being utilized to generate the control signal.

20. The method of claim 11 further comprising determining when to wake up the at least one component when the at least one component is in a standby or power off mode.

21. The method of claim 11 wherein generating the control signal comprises generating a control signal which powers off the at least one component during a guard band time.

22. A system for conserving power in a receiver device comprising:

means for receiving a signal;

means for demodulating at least one sampled signal of the received signal;

means for processing at least one demodulated signal into an output format; and

means for generating a control signal to switch at least one component within the receiver device between modes to conserve power.
