ABSTRACT:
Systems and methods of providing alerts on a recording device. The alerting service is provided on a digital video recorder (DVR) or other computing device as an application that is loaded into memory. The DVR is configured with geographic information and is able to determine its geographic location. A data channel is used for receiving the emergency bulletins. A central database system receives the emergency bulletins and transmits to the DVR. The DVR may process the bulletins to select those which are geographically relevant. The DVR displays the bulletins on top of the video signal that it is sending to a display device. The bulletin is displayed even if the user is pausing, rewinding, fast-forwarding, altering the display of the program content, or controlling the DVR.
