1. A method for rendering an alert message on a digital radio broadcast receiver, said method comprising:
- controlling said digital radio broadcast receiver to maintain a power condition in which a clock function is powered on and in which tuner functions and rendering functions are powered off;
controlling said digital radio broadcast receiver to periodically power on said tuner functions to receive a digital radio broadcast signal;
receiving a digital radio broadcast signal at said digital radio broadcast receiver;
detecting data corresponding to an alert message within said digital radio broadcast signal, said data comprising message information and category type information of the detected alert message, wherein the category type information identifies a category of said message information conveyed by the alert message;
determining with a processing system whether said category type information of the detected alert message satisfies a triggering condition corresponding to a category type of alert message pre-selected by the user at a user interface of the digital radio broadcast receiver as a category of alert message that the user desires to receive;
if said triggering condition is satisfied, powering on said rendering functions of said digital radio broadcast receiver and rendering said message information of said alert message at said digital radio broadcast receiver; and
if said triggering condition is not satisfied, powering off said tuner functions of said digital radio broadcast receiver.

Abstract
A method for rendering an alert message on a digital radio broadcast receiver is described. A digital radio broadcast signal is received at the digital radio broadcast receiver. Data corresponding to an alert message comprising type information for identifying a type of the alert message and message information is detected. If the type information satisfies a triggering condition for a type of alert message pre-selected by a user of the digital radio broadcast receiver, the message information is rendered at the digital radio broadcast receiver. A digital radio broadcast receiver that performs the method is also described.

8. A digital radio broadcast receiver for rendering an alert message, said digital radio broadcast receiver comprising:
-
a tuner; a processing system; and a user interface comprising an input system for allowing said user to select which of multiple types of alert message are to be rendered, wherein said processing system is configured to; maintain a power condition in which a clock is powered on and in which said tuner and said user interface are powered off; periodically power on said tuner to receive said digital radio broadcast signal; detect data corresponding to an alert message within said digital radio broadcast signal, said data comprising message information and category type information of the detected alert message, wherein the category type information identifies a category of said message information conveyed by the alert message; determine whether said category type information of the detected alert message satisfies a triggering condition corresponding to a category type of alert message pre-selected by the user at a user interface of the digital radio broadcast receiver as a category of alert message that the user desires to receive; and if said triggering condition is satisfied, powering on said user interface of said digital radio broadcast receiver to cause said message information of said alert message to be rendered at said digital radio broadcast receiver; if said triggering condition is not satisfied, powering off said tuner functions of said digital radio broadcast receiver. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An article of manufacture comprising a computer usable medium having computer readable program code embodied therein for rendering an alert message on a digital radio broadcast receiver, said computer readable program code adapted to cause a processing system of said digital radio broadcast receiver to:
-
control said digital radio broadcast receiver to maintain a power condition in which a clock function is powered on and in which tuner functions and rendering functions are powered off; control said digital radio broadcast receiver to periodically power on said tuner functions to receive said digital radio broadcast signal; detect data corresponding to an alert message within a digital radio broadcast signal, said data comprising message information and category type information of the detected alert message, wherein the category type information identifies a category of said message information conveyed by the alert message; determine whether said category type information of the detected alert signal satisfies a triggering condition corresponding to a category type of alert message pre-selected by a user at a user interface of the digital radio broadcast receiver as a category of alert message that the user desires to receive; if said triggering condition is satisfied, cause said message information of said alert message to be rendered at said digital radio broadcast receiver; and if said triggering condition is not satisfied, cause said tuner functions to power off. - View Dependent Claims (16, 17, 18, 19, 20, 21)
