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.
Claims16
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 control signal that switches a component within the receiver device between power modes in response to a request for a service issued by a user.
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;
- and
- generating a control signal to switch a component within the receiver device between power modes, wherein the control signal is based on the time slot.
