Low power digital media broadcast receiver with time division
First Claim
1. A system for power conservation in a receiver device, comprising:
- a tuner that receives a signal at the receiver device;
a demodulator that demodulates a sampled signal into a demodulated signal, wherein the sampled signal is based on the signal received by the tuner;
a payload processor that processes the demodulated signal into a transmission frame having multiple channels corresponding to services, wherein a service occupies a continuous timeslot in the transmission frame; and
time division control logic stored in memory and executable by a processor to;
generate a first control signal that switches a first component within the receiver device between power modes in response to a request for a service issued by a user, andgenerate a second control signal that switches a second component within the receiver device between power modes, and wherein transitions between the power modes are timed to occur non-simultaneously for the first component and the second component.

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.

8. A method for conserving power in a receiver device, comprising:
-
receiving a signal at the receiver device; demodulating a sampled signal of the received signal into a demodulated signal; processing the demodulated signal into a transmission frame having multiple channels corresponding to services, wherein a service occupies a continuous timeslot in the transmission frame; determining a time slot in the transmission frame corresponding to a service requested by a user; generating a first control signal to switch a first component within the receiver device between power modes, wherein the first control signal is based on the time slot; determining a second time slot in the transmission frame corresponding to a second service requested by the user; and generating a second control signal to switch a second component within the receiver device between power modes, wherein the second control signal is based on the second time slot, and wherein transitions between the power modes occur independently between the first control signal and the second control signal. - View Dependent Claims (9, 10, 11, 12, 13, 14)
