ABSTRACT:
Broadcast receivers operate in a power-saving standby mode while retaining the ability to receive broadcast program, software, and firmware updates. The most power hungry circuits are deprived of power in the standby mode using a wake-up switch controlled by an update sensor that actively monitors the broadcast channel in the standby mode. If the receiver receives an update-pending indication while in the standby mode, then the wake-up switch provides power to those components needed to receive the update without indicating a power-on condition to the user.
