Abstract

A device configured to receive a request, from a server, to provide frequency code information identifying a frequency code. The frequency code includes frequencies to be emitted by a broadcasting device that presents a first content. The device may generate a code based on the request. The device may receive a second content from the server. The device may store the second content and the code so that the second content is associated with the code. The device may generate the frequency code information based on the code. The device may provide the frequency code information for the frequency code to be emitted by the broadcasting device. The device may receive the code from a listening device that detected the frequency code emitted by the broadcasting device. The device may provide the second content associated with the code to the listening device.

First claim

What is claimed is:

1. A first server comprising:
one or more processors to:
receive a request, from a second server, to provide frequency code information identifying a frequency code,
the frequency code including information identifying frequencies to be emitted by a broadcasting device that presents a first content,
the frequency code including information identifying a start frequency indicating a start of the frequency code and information identifying an end frequency indicating an end of the frequency code, and
the request being received with a second content from the second server,
the second content being associated with the first content;

generate, based on the request, a code associated with the second content,
the code including one or more characters, and
the code to be used to retrieve the second content;

store the second content and the code;
generate the frequency code information based on the one or more characters, included in the code, and a data structure stored by the first server,
the data structure storing different characters in association with different frequencies,
each character, of the different characters, being associated with a respective frequency of the different frequencies,
the start frequency and the end frequency each being different from the different frequencies associated with the different characters, and
the start frequency and the end frequency being different than another start frequency and another end frequency,
the other start frequency and the other end frequency being associated with another frequency code representing another second content;

provide, to the second server, the frequency code information for the frequency code to be emitted by the broadcasting device,
the second server providing the first content with the frequency code information for the frequency code to the broadcasting device,
the frequency code information including:
the start frequency,
the end frequency, and
the code to be used to retrieve the second content,

the broadcasting device to emit the frequency code while presenting the first content;

receive the code from a listening device that detected the frequency code emitted by the broadcasting device; and
provide the second content associated with the code to the listening device based on receiving the code from the listening device.

2. The first server of claim 1 , where the frequency code includes inaudible frequencies to be emitted by the broadcasting device.

3. The first server of claim 1 , where the second content supplements the first content.

4. The first server of claim 1 , where the one or more processors are further to:
store another data structure that associates the second content and the code;
query the other data structure using the code received from the listening device; and
retrieve the second content associated with the code based on querying the other data structure.

5. The first server of claim 1 , where the frequency code is less than one second in length.

6. The first server of claim 1 , where the different frequencies, the start frequency, and the end frequency are greater than 15 KHz.

7. A non-transitory computer-readable medium storing instructions, the instructions comprising:
a plurality of instructions that, when executed by a processor of a first server, cause the processor to:
receive a request, from a second server, to provide a frequency code file,
the frequency code file identifying a frequency code to be played while a broadcasting device presents a first content,
the frequency code including information identifying a start frequency indicating a start of the frequency code and information identifying an end frequency indicating an end of the frequency code, and
the request being received with a second content from the second server,
the second content being associated with the first content;

generate, based on the request, a code associated with the second content,
the code including one or more characters, and
the code to be used to retrieve the second content;

store the second content in association with the code;
generate the frequency code file based on the one or more characters of the code and a data structure stored by the first server,
the data structure storing different characters in association with different frequencies,
each character, of the different characters, being associated with a respective frequency of the different frequencies,
the start frequency and the end frequency each being different from the different frequencies associated with the different characters, and
the start frequency and the end frequency being different than another start frequency and another end frequency,
the other start frequency and the other end frequency being associated with another frequency code representing another second content;

send, to the second server, the frequency code file for the frequency code to be played by the broadcasting device while presenting the first content,
the second server providing the first content with the frequency code file to the broadcasting device,
the frequency code file including:
the start frequency,
the end frequency, and
the code to be used to retrieve the second content,

the broadcasting device to provide the frequency code while presenting the first content;

receive the code from a listening device that detected the frequency code provided by the broadcasting device; and
send, based on receiving the code from the listening device, the second content associated with the code to the listening device to be presented.

8. The non-transitory computer-readable medium of claim 7 , where the frequency code file is an audio file.

9. The non-transitory computer-readable medium of claim 7 , where the frequency code is less than one second in length.

10. The non-transitory computer-readable medium of claim 7 , where the plurality of instructions, to send the frequency code file to the second server, cause the processor to:
send a plurality of frequency code files, to the second server, that identify frequency codes to be played by the broadcasting device while presenting a same first content,
the plurality of frequency code files including the frequency code file, and
the frequency codes including the frequency code.

11. The non-transitory computer-readable medium of claim 10 ,
where the plurality of frequency code files is associated with a plurality of second content, the plurality of second content including the second content, and
where the plurality of instructions, to send the second content to the listening device, cause the processor to:
send the plurality of second content to the listening device to be presented while the broadcasting device presents the same first content.

12. The non-transitory computer-readable medium of claim 7 , where the different frequencies, the start frequency, and the end frequency are greater than 15 KHz.

13. The non-transitory computer-readable medium of claim 7 , where the frequency code includes inaudible frequencies to be emitted by the broadcasting device.

14. The non-transitory computer-readable medium of claim 7 , where the plurality of instructions further cause the processor to:
store another data structure that associates the second content and the code;
query the other data structure using the code received from the listening device; and
retrieve the second content associated with the code based on querying the other data structure.

15. A method comprising:
receiving, by a device, a request, from a server, to provide fr
