System and method for improved updating and annunciation of traffic enforcement camera information in a vehicle using a broadcast content delivery service
First Claim
1. A method of providing traffic enforcement camera location data to a receiver comprising the steps of:
- receiving a broadcast signal comprising a plurality of program channels and at least one data channel that has been transmitted to a plurality of receivers, the receiver corresponding to one of the plurality of receivers that are each configured to receive the broadcast signal and demultiplex at least one selected program channel and the data channel therefrom, the data channel comprising traffic enforcement camera data that is periodically updated and is from a content provider that verifies the traffic enforcement camera data, the traffic enforcement camera data comprising at least camera location data and identification data indicating the type of camera selected from a plurality of different types of traffic enforcement cameras;
storing in a memory device of the receiver at least a subset of the traffic enforcement camera data corresponding to a plurality of traffic enforcement cameras;
demultiplexing the data channel from the received broadcast signal;
updating the traffic enforcement camera data stored in the memory device when the demultiplexed data channel comprises at least one of traffic enforcement camera data for a new traffic enforcement camera, data indicating deletion of the stored traffic enforcement camera data for an identified traffic enforcement camera, and data indicating edits to the stored traffic enforcement camera data for an identified traffic enforcement camera;
obtaining position data corresponding to the location of the receiver;
comparing the position data of the receiver with the camera location data stored in the memory device; and
annunciating selected traffic enforcement camera data from the memory device that corresponds to one or more traffic enforcement cameras located within a selected geographic range of the receiver.

Abstract
An enhanced broadcast data service with reports locations of traffic enforcement camera locations (e.g., red light cameras and speed cameras) to users. Traffic enforcement camera information is aggregated, verified (e.g., particularly as to traffic enforcement camera type) and stored (e.g., at a server). A broadcast signal comprising program channels and at least one data channel having traffic enforcement camera information is transmitted to a plurality of receivers. Receivers store at least a subset of the traffic enforcement camera information available from the server and synchronize to it using periodic transmitted updates. Receivers compare receiver location data with stored camera location data, and display or generate audible alerts when the receiver is within a selected geographic range of a traffic enforcement camera. Alerts can be filtered as to camera type. A alerts can employ different color camera icons superimposed on a screen map depending on camera type or whether the camera is newly added.

15. A broadcast system providing an enhanced data service for traffic enforcement camera location reporting, the broadcast system being configured to transmit a Satellite Digital Audio Radio Service (SDARS) broadcast stream comprising a plurality of audio programming channels and at least one data channel comprising traffic enforcement camera location information indicating the locations of at least speed cameras, comprising:
an in-vehicle system comprising a processing device, a memory device and a broadcast receiver, the broadcast receiver being configured to receive the SDARS broadcast stream and demultiplex the data channel therefrom to obtain the traffic enforcement camera location information, the processing device being configured to store at least a subset of the demultiplexed traffic enforcement camera location information in an in-vehicle database in the memory device and to annunciate information relating to selected traffic enforcement camera locations retrieved from the in-vehicle database using a vehicle user interface system comprising at least one of a tuner, a display and at least one speaker provided in a vehicle, the annunciated information comprising at least one of an audible alert via the speaker and a visual alert via the display of the location of at a traffic enforcement camera within a selected geographic range of the vehicle. - View Dependent Claims (16, 17, 18)
