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.
