Abstract

TV receiver apparatus (1) and a related method are disclosed, the TV receiver apparatus comprising a video signal receiver (2) for receiving video signals transmitted from an external video signal transmitter, a GPS signal receiver (3) for receiving GPS signals transmitted from an external GPS signal transmitter and signal coupling means (4) connected to both receivers. The signal coupling means is adapted to provide both receivers with respective video and GPS signals via a common antenna (5) where the antenna is adapted to receive terrestrially broadcasted video signals.

Claims

1. TV receiver apparatus comprising a video signal receiver for receiving video signals transmitted from an external, terrestrially based video signal transmitter, a GPS signal receiver for receiving GPS signals transmitted from an external GPS signal transmitter and signal coupling means connected to both receivers and adapted to provide both receivers with respective video and GPS signals via a common antenna.

2. Apparatus according to claim 1 wherein the TV receiver apparatus and the coupling means are contained in a common housing.

3. Apparatus according to claim 1 further comprising an antenna connected to the coupling means and adapted to optimally receive terrestrially broadcasted video signals.

4. Apparatus according to claim 3 wherein the antenna is adapted to optimally receive video signals broadcasted at UHF or VHF bands.

5. Apparatus according to claim 1 further comprising a GPS processor for acquiring and tracking received GPS signals and a TV signal processor for decoding the received TV signals, both provided in the form of a single dual-purpose microprocessor.

8. The TV receiver apparatus of claim 3, wherein the antenna is a log-periodic antenna.

6. A method of receiving video and GPS signals in TV receiver apparatus comprising a video signal receiver and a GPS signal receiver both connected via signal coupling means to a common antenna, the method comprising the steps of:

(a) receiving, via the antenna, video signals in the video signal receiver from an external, terrestrially based video signal transmitter; and

(b) receiving, via the antenna, GPS signals in the GPS signal receiver from an external GPS signal transmitter.

7. A method according to claim 6 wherein the antenna is adapted to optimally receive UHF or VHF video signals.

9. The TV receiver apparatus of claim 7, wherein the video signals and the GPS signals are received via a log periodic antenna.

10. A television reception system, comprising:

a video signal receiver adapted to receive a terrestrially broadcast video signal;

a global positioning system (GPS) receiver adapted to receive GPS signals from at least one satellite; and

an antenna feed adapted to receive from a single antenna both the terrestrially broadcast video signal and the GPS signals, to provide the terrestrially broadcast video signal to the video signal receiver, and to provide the GPS signals to the GPS receiver.

11. The television reception system of claim 10, wherein the GPS receiver is adapted to receive the GPS signals, via the antenna feed, from a log-periodic antenna.

12. The television reception system of claim 10, further comprising:

a GPS signal processor adapted to identify a location of the television reception system based on the received GPS signals; and

a TV signal processor adapted to decode the received terrestrially broadcast video signal.

13. The television reception system of claim 12, further comprising:

means for storing a location code for the television reception system; and

video signal decoding prevention means for preventing the received video signal from being decoded by the TV signal processor when the location detected by the GPS receiver does not match the location code.

14. The television reception system of claim 10, further comprising a single microprocessor adapted both to identify a location of the television reception system based on the received GPS signals, and to decode the received terrestrially broadcast video signal.

15. The television reception system of claim 14, further comprising:

means for storing a location code for the television reception system; and

video signal decoding prevention means for preventing the received video signal from being decoded by the microprocessor when the location detected by the micro-processor does not match the location code.

16. A method of receiving television signals, comprising:

receiving, via a single antenna, a video signal broadcast from a terrestrial broadcast antenna, and a global positioning system (GPS) signal transmitted from at least one satellite;

providing the GPS signal to a GPS receiver; and

providing the video signal to a video signal receiver.

17. The method of claim 16, wherein the antenna is a log-periodic antenna.

18. The method of claim 16, further comprising identifying a location of an apparatus executing the method of receiving television signals, based on the received GPS signals.

19. The method of claim 18, further comprising:

accessing a location code stored in a memory device; and

decoding the video signal when the a location of the apparatus executing the method of receiving television signals matches the location code.
