Abstract

A system and method for implementing location-based content restrictions in a mobile video broadcast is provided. The invention utilizes DVB-H KSMs to transmit the restrictions and thereby enables the restrictions to be enforced by the mobile terminal receiving a broadcast video signal. This need for enforcement is determined as a function of the received KSMs and the physical location of the receiving terminal (as sensed using one or more accepted navigation technologies (e.g., Global Positioning System (“GPS”) technology, Assisted GPS (“AGPS”) technology, etc.).

Claims

1. A terminal-based system for enforcing location-based content restrictions in a mobile video broadcast comprising:

an antenna adapted for receiving at least one broadcast DVB-H compliant digital video transmission within a broadcasting region;

a terrestrial location sensor adapted to determine the terminal'"'"'s physical location using one or more terrestrial navigation technologies;

a key stream layer implementing a location-contingent content rendering syntax whereby the terminal gains access to DVB-H content associated with the syntax unless the terminal is located within a blacked-out geographic location within the broadcast region.

2. The terminal-based system of claim 1 wherein the one or more terrestrial navigation technologies includes GPS.

3. The terminal-based system of claim 1 wherein the one or more terrestrial navigation technologies includes AGPS.

4. The terminal-based system of claim 1 wherein the blacked-out geographic location is defined by an ellipse.

5. The terminal-based system of claim 1 wherein the blacked-out geographic location is defined by a polygon.

6. The terminal-based system of claim 1 further comprising an override syntax which when received by a terminal enables access to DVB-H content associated with the syntax regardless of the terminal being located within a blacked-out geographic location.

7. A method for implementing a terminal-based system for the enforcement of location-based content restrictions in a mobile video broadcast comprising the steps of:

receiving at a terminal least one broadcast DVB-H compliant digital video transmission within a broadcasting region;

sensing the terminal'"'"'s physical location using one or more terrestrial navigation technologies;

implementing a key stream layer dependent ESG whereby the terminal gains access to DVB-H content associated with the key stream layer unless the terminal is located within a blacked-out geographic location within the broadcast region.

8. The method of claim 7 wherein the one or more terrestrial navigation technologies includes GPS.

9. The method of claim 7 wherein the one or more terrestrial navigation technologies includes AGPS.

10. The method of claim 7 wherein the blacked-out geographic location is defined by an ellipse.

11. The method of claim 7 wherein the blacked-out geographic location is defined by a polygon.

12. The method of claim 7 further comprising the step of:

responding to an a override syntax and thereby enabling access to DVB-H content associated with the syntax regardless of the terminal being located within a blacked-out geographic location.
