Abstract

A method and system optimally selecting antenna elements based on the current availability of antenna elements and the current usage of other antenna elements within a two or three dimensional array. The present system and method pertain to an approach to allow the maximal usage of each antenna element while simultaneously reducing the coupling between antenna elements to improve the signal strength in each antenna element by ensuring that antenna elements in the same incident path are not tuned to the same frequency or physically or electrically near elements tuned to identical or adjacent frequencies.

Claims

1. A method of assigning antenna elements of an antenna array, the method comprising:

receiving user requests for content broadcast by broadcasting entities on channels; and

assigning the user requests to the antenna elements of the antenna array to minimize coupling with other antenna elements based on the channels of the content for the user requests and the channels to which the other antenna elements are tuned by assigning the user requests to the antenna elements to maximize distance from other antennas elements tuned to a same and/or similar channel.

2. The method according to claim 1, wherein the user requests include requests for live streaming content.

3. The method according to claim 2, wherein the user requests for content include requests to record content.

4. The method according to claim 3, further comprising prioritizing the user requests for the live streaming content before the user requests to record content.

5. The method according to claim 4, further comprising assigning the user requests for the live streaming content before assigning the user requests to record content.

6. A method of assigning antenna elements of an antenna array, the method comprising:

receiving user requests for content broadcast by broadcasting entities on channels; and

assigning the user requests to the antenna elements of the antenna array to minimize coupling with other antenna elements based on the channels of the content for the user requests and the channels to which the other antenna elements are tuned by assigning the user requests to the antenna elements based on bandwidths of the antenna elements, channels to which the other antenna elements are tuned, direction of the other antenna elements, polarization of the other antenna elements, and/or distance between the antenna elements.

7. A method of assigning antenna elements of an antenna array, the method comprising:

receiving user requests for content broadcast by broadcasting entities on channels;

assigning the user requests to the antenna elements of the antenna array to minimize coupling with other antenna elements based on the channels of the content for the user requests and the channels to which the other antenna elements are tuned; and

dropping users requests for channels if coupling between the assigned antenna elements to other antenna elements exceeds a predefined threshold.

8. A method of assigning antenna elements of an antenna array, the method comprising:

receiving user requests for content broadcast by broadcasting entities on channels;

assigning the user requests to the antenna elements of the antenna array to minimize coupling with other antenna elements based on the channels of the content for the user requests and the channels to which the other antenna elements are tuned; and

minimizing coupling with the other antenna elements by assigning the user requests to the antenna elements based on a direction between the antenna elements and other antennas elements tuned to a same and/or similar channel and a direction of a transmitter of the broadcasting entities.

9. A system for capturing content broadcast by broadcasting entities, the system comprising:

an array of antenna elements for receiving the content broadcast by the broadcasting entities on channels; and

an antenna controller that assigns the user requests to the antenna elements of the antenna array to minimize coupling with other antenna elements based on the channels of the content for the user requests and the channels to which the other antenna elements are tuned, wherein the antenna controller minimizes coupling with the other antenna elements by assigning the user requests to the antenna elements to maximize distance from other antennas elements tuned to a same and/or similar channel.

10. The system according to claim 9, wherein the user requests include requests for live streaming content.

11. The system according to claim 10, wherein the user requests for content include requests to record content.

12. The system according to claim 11, wherein the antenna controller prioritizes user requests for the live streaming content before the user requests to record content.

13. The system according to claim 12, wherein the antenna controller assigns the user requests for the live streaming content before assigning the user requests to record content.

14. A system for capturing content broadcast by broadcasting entities, the system comprising:

an array of antenna elements for receiving the content broadcast by the broadcasting entities on channels; and

an antenna controller that assigns the user requests to the antenna elements of the antenna array to minimize coupling with other antenna elements based on the channels of the content for the user requests and the channels to which the other antenna elements are tuned, wherein the antenna controller minimizes coupling with the other antenna elements by assigning the user requests to the antenna elements based on bandwidths of the antenna elements, channels to which the other antenna elements are tuned, direction of the other antenna elements, polarization of the other antenna elements, and/or distance between the antenna elements.

15. A system for capturing content broadcast by broadcasting entities, the system comprising:
