Antenna system with individually addressable elements in dense array
View Patent ↗A method and system for capturing, storing, and streaming over the air broadcasts based on user requests is disclosed. The system and method utilize subarrays of antenna elements for receiving over the air broadcasts. Processing pipelines are used to demodulate, transcode and index the content transmissions to produce content data that are streamed to users. In this way, the feeds from antennas can be accessed by users over a network connection.
1. An antenna system comprising:
a plurality of circuit boards, each of the circuit boards including a two dimensional array of antenna elements for separately receiving over the air broadcasts and an encoder system for simultaneously demodulating the over air broadcasts received by the separate antenna elements, the encoder system transcoding the over the air broadcasts from MPEG2 content data;
a card cage for housing the circuit boards,
an antenna optimization and control system that determines which of the antenna elements within the antenna array are available and optimized to receive particular over the air broadcasts requested by users and uses those antenna elements to receive over the air broadcasts for those users; and
a data storage system that stores the content data from the encoder system.
2. The system according to claim 1 , wherein the two dimensional array of antenna elements has a density of at least 10 antenna elements per square meter.
3. The system according to claim 1 , wherein the antenna elements are omni-directional antenna elements.
4. The system according to claim 1 , wherein the antenna elements are symmetric dual loop antenna elements.
5. The system according to claim 1 , wherein the two dimensional arrays of antenna elements form a three dimensional array within the card cage.
6. The system according to claim 1 , wherein each of the encoder systems comprises demodulators that are implemented on each of the circuit boards.
7. The system according to claim 1 , further comprising radio frequency tuners on the circuit boards for tuning the antenna elements of the two dimensional array.
8. The system according to claim 1 , wherein each of the circuit boards comprises at least 50 antenna elements.
9. The system according to claim 1 , wherein the antenna elements are hemispherical directional antenna elements.
10. The system according to claim 1 , wherein the antenna optimization and control system determines which of the antenna elements should receive the particular over the air broadcasts by comparing received signal strength indicator values of different antenna elements.
11. A method for receiving over the air broadcasts with an array of antenna elements, the method comprising:
providing two dimensional arrays of antennas elements for receiving the over the air broadcasts;
stacking the arrays to form a three dimensional array of antenna elements;
determining which of the antenna elements within the antenna array are available and optimized to receive particular over the air broadcasts requested by users and using those antenna elements to receive over the air broadcasts for those users:
receiving the over the air broadcasts with the three dimensional array of antenna elements; and
simultaneously demodulating and transcoding the over the air broadcasts received by the antenna elements from MPEG2 content data to be stored in a data storage device.
12. The method according to claim 11 , wherein each array of antennas elements has a density of at least 10 antenna elements per square meter.
13. The method according to claim 11 , further comprising stacking the two dimensional arrays of antenna elements in a card cage.
14. The method according to claim 11 , further comprising implementing tuners for the antenna elements on the circuit boards that also have the two dimensional arrays of antennas elements.
15. The method according to claim 11 , further comprising providing at least 50 antenna elements in each of the two dimensional arrays.
16. The method according to claim 11 , wherein the antenna elements of the two dimensional arrays of antenna elements have a density of at least 50 antenna elements per square meter.
17. The method according to claim 11 , further comprising determining which of the antenna elements should receive the particular over the air broadcasts by comparing received signal strength indicator values of different antenna elements.
