Abstract
An example method for notifying a battery-powered device of the presence of high priority broadcast content while enabling the device to conserve battery power includes generating a high priority broadcast signal. The signal includes a high priority symbol identifier for informing the battery powered device to switch from an idle state to an acquisition state to inspect the remainder of the high priority broadcast signal. The signal further includes a high priority indication symbol for informing the battery powered device to transition to an active state from the acquisition state to receive high priority broadcast content before returning to the idle state. The signal further includes a timing symbol for informing the battery powered device of the minimum time period until a next a high priority broadcast signal should be expected, enabling the battery powered device to remain in the idle state until the next high priority broadcast signal.
