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.

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.
