Low power digital media broadcast receiver with time division
View Patent ↗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.
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;
time division control logic stored in memory and executable by a processor to generate a control signal to switch at least one component within the receiver device between modes to conserve power; and
circuitry for 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 by the time division control logic to generate the control signal.
2. The system of claim 1 wherein the modes comprise an active mode.
3. The system of claim 1 wherein the modes comprise c 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 executable to determine the at least one component in which to switch modes.
8. 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;
generating a control signal to switch at least one component within the receiver device between modes to conserve power; and
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.
9. The method of claim 8 wherein the modes comprise an active mode.
10. The method of claim 8 wherein the triodes comprise a standby mode.
11. The method of claim 8 wherein the modes comprise a power off mode.
12. The method of claim 8 wherein the modes comprise a low power mode.
13. The method of claim 8 wherein generating the control signal comprises generating a control signal which transitions the at least one component between a plurality of staggered modes.
14. The method of claim 8 further comprising determining the at least one component in which to switch modes.
15. The method of claim 8 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.
