Abstract

Techniques are described for expanding and/or improving the Advanced Television Systems Committee (ATSC) 3.0 television protocol in robustly delivering the next generation broadcast television services. A receiver, to automatically switch from presenting a service on a first frequency to a second frequency such as when a mobile receiver is moving through a boundary region between two broadcasters, can consider not just signal strength and error rates of two frequencies carrying the same service to select which frequency to tune to, but also relative location and direction of motion of the receiver with respect to each broadcaster.

First claim

What is claimed is:

1. In digital television in which at least one receiver can receive broadcast signals from at least first and second digital television broadcast assemblies, a method, comprising:
identifying that a service is received on at least first and second frequencies;
identifying for each first and second frequency at least first and second respective quality metrics;
identifying at least one parameter selected from: at least one topographical feature in a region in which the receiver is disposed, at least first and second locations of respective first and second transmitters broadcasting the respective first and second frequencies, at least first and second distances between the receiver and the first and second locations of the respective first and second transmitters, at least respective first and second relative motions between the receiver and the respective first and second locations, at least respective first and second elevations of the respective first and second transmitters;
selecting whether to tune to the first frequency or the second frequency at least in part based on the at least one parameter; and
presenting on at least one audio video display device the service received on the first or second frequency as selected based on the at least one parameter.

2. The method of claim 1 , wherein the digital television receiver comprises an advanced television systems committee (ATSC) 3.0 receiver.

3. The method of claim 1 , comprising selecting whether to tune to the first frequency or the second frequency at least in part based on the at least one parameter and based on the first and second quality metrics.

4. The method of claim 1 , comprising selecting whether to tune to the first frequency or the second frequency at least in part based on at least one topographical feature in a region in which the receiver is disposed.

5. The method of claim 1 , comprising selecting whether to tune to the first frequency or the second frequency at least in part based on at least the first and second locations of the respective first and second transmitters broadcasting the respective first and second frequencies.

6. The method of claim 1 , comprising selecting whether to tune to the first frequency or the second frequency at least in part based on at least the first and second distances between the receiver and the first and second locations of the respective first and second transmitters.

7. The method of claim 1 , comprising selecting whether to tune to the first frequency or the second frequency at least in part based on at least the respective first and second directions of travel between the receiver and the respective first and second locations.

8. The method of claim 1 , comprising selecting whether to tune to the first frequency or the second frequency at least in part based on at least the respective first and second elevations of the respective first and second transmitters.

9. The method of claim 1 , comprising selecting a frequency at least in part using at least one machine learning (ML) model.

10. The method of claim 1 , comprising altering at least one configuration of at least one antenna based at least in part on which frequency is selected.

11. An apparatus comprising:
at least one receiver configured to:
select a first frequency from a first transmitter or a second frequency from a second transmitter, both frequencies carrying substantially the same digital television service, based at least in part on at least one parameter selected from: at least one topographical feature in a region in which the receiver is disposed, at least first and second locations of the respective first and second transmitters, at least first and second distances between the receiver and the first and second locations of the respective first and second transmitters, at least respective first and second relative motions between the receiver and the respective first and second locations, at least respective first and second elevations of the respective first and second transmitters; and
present on at least one audio video display device the service received on the first or second frequency as selected based on the at least one parameter.

12. The apparatus of claim 11 , wherein the receiver is configured to:
identify for each first and second frequency at least first and second respective quality metrics; and
select whether to tune to the first frequency or the second frequency at least in part based on the at least one parameter and based on the first and second quality metrics.

13. The apparatus of claim 11 , wherein the receiver is configured to select whether to tune to the first frequency or the second frequency at least in part based on at least one topographical feature in a region in which the receiver is disposed.

14. The apparatus of claim 11 , wherein the receiver is configured executable to select whether to tune to the first frequency or the second frequency at least in part based on at least the first and second locations of the respective first and second transmitters broadcasting the respective first and second frequencies.

15. The apparatus of claim 11 , wherein the receiver is configured to select whether to tune to the first frequency or the second frequency at least in part based on at least the first and second distances between the receiver and the first and second locations of the respective first and second transmitters.

16. The apparatus of claim 11 , wherein the receiver is configured to select whether to tune to the first frequency or the second frequency at least in part based on at least the respective first and second directions of travel between the receiver and the respective first and second locations.

17. The apparatus of claim 11 , wherein the receiver is configured to select whether to tune to the first frequency or the second frequency at least in part based on at least the respective first and second elevations of the respective first and second transmitters.

18. A digital television apparatus comprising:
at least one receiver comprising at least one processor programmed with instructions to configure the processor to:
select between a first frequency from a first transmitter and providing a digital television service and a second frequency from a second transmitter and providing the digital television service based at least in part on first and second quality metrics associated with the respective first and second frequencies and at least one geographic parameter related to at least one of the first and second transmitters and/or to a region associated with at least one of the first and second transmitters.

19. The digital television apparatus of claim 18 , wherein the instructions are executable to select between the first frequency from the first transmitter providing the digital television service and the second frequency from the second transmitter providing the digital television service based at least in part on the first and second quality metrics associated with the respective first and second frequencies and at least one geographic parameter related to at least one of the first and second transmitters, wherein
at least one geographic parameter is selected from: at least one topographical feature in a region in which the receiver is disposed, at least first and second locations of the respective first and second transmitters, at least first and second distances between the receiver and the first and second locations of the respective first and second transmitters, at least respective first and
