System and method for conserving energy in a digital home networking device

摘要

A method and apparatus configures a power level for a device able to receive audio, video, and data signals. An input signal is received by a receiver capable of receiving broadcast data signals and digital home networking signals. The system determines if the receiver is operating in a first mode having a first power level or a second mode having a second power level based on a type of input signal received by the receiver. A control signal is generated for modifying at least one setting on a first circuit for configuring the first circuit to operate according to the first power level if the input signal is a first type of input signal. The control signal is provided to the first circuit and the first circuit is configured to operate according to the first power level based on the control signal.

1. A method for controlling power level used in a signal receiving device, the method comprising the steps of:
receiving at least one of a first type of input signal and a second type of input signal through an input of the signal receiving device; determining if the received signal is of the first type of input signal or the second type of input signal; generating a first control signal associated with a first operational mode, the first control signal configuring a power level for use in a first mode of operation if the received signal is of the first type of input signal; determining at least one characteristic of an operational environment of the signal receiving device to identify a preferred mode of operation if the input signal is a second type of input signal; generating a second control signal associated with a second operational mode, the second control signal configuring a power level for use in a second mode of operation based on the identified preferred mode of operation if the received signal is of the second type of input signal; providing the first control signal and second control signal to a first circuit; and configuring a power level of the first circuit based on the first control signal and second control signal.
