Internet radio stream generation
A system includes a first source interface, a second source interface, a content mixer, a first communication interface (CI), and a second CI. The first source interface and the second source interface are configured to receive a first audio signal (FS) and a second audio signal (SS), respectively. The content mixer is configured to generate a portion of a terrestrial broadcast stream (TBS portion) that includes the FS and the SS. A first segment of the FS overlaps a second segment of the SS. The content mixer is configured to generate a portion of an internet radio stream (IR portion) corresponding to the TBS portion. The IR portion includes the first segment and omits the SS. The first CI is configured to send the TBS portion to a terrestrial radio station. The second CI is configured to send the IR portion to a content replacer. Other aspects are also disclosed.
1. A system comprising:
a first source interface configured to receive a first audio signal from a first source;
a second source interface configured to receive a second audio signal from a second source;
a content mixer configured to:
generate a portion of a terrestrial broadcast stream, the portion of the terrestrial broadcast stream including the first audio signal and the second audio signal, wherein a first segment of the first audio signal overlaps a second segment of the second audio signal; and
generate a portion of an internet radio stream corresponding to the portion of the terrestrial broadcast stream, the portion of the internet radio stream including the first segment of the first audio signal and omitting the second audio signal;
a first communication interface configured to send the portion of the terrestrial broadcast stream to a terrestrial radio station; and
a second communication interface configured to send the portion of the internet radio stream to a content replacer.
2. The system of claim 1 , wherein the content mixer is further configured to insert a control tag in the portion of the internet radio stream, the control tag indicating a content replacement point.
3. The system of claim 2 , further comprising an input interface configured to receive a user input, wherein the content mixer is configured to insert the control tag in response to receiving the user input.
4. The system of claim 2 , wherein the content mixer is further configured to insert the control tag in response to detecting a characteristic of the second audio signal.
5. The system of claim 1 , wherein the second audio signal includes content associated with a broadcast region of the terrestrial radio station.
6. A method comprising:
generating, at a device, a portion of a terrestrial broadcast stream, the portion of the terrestrial broadcast stream including a first audio signal from a first source and a second audio signal from a second source, wherein a first segment of the first audio signal overlaps a second segment of the second audio signal;
generating, at the device, a portion of an internet radio stream corresponding to the portion of the terrestrial broadcast stream, the portion of the internet radio stream including the first segment of the first audio signal and omitting the second audio signal;
sending the portion of the terrestrial broadcast stream from the device to a terrestrial radio station; and
sending the portion of the internet radio stream from the device to a content replacer.
7. The method of claim 6 , wherein the second source includes an advertising source.
8. The method of claim 6 , wherein the second audio signal includes audio of an advertisement.
9. The method of claim 6 , further comprising inserting, at the device, a control tag in the portion of the internet radio stream, the control tag indicating a content replacement point.
10. The method of claim 9 , wherein the control tag is inserted at the end of the first audio signal.
11. The method of claim 9 , wherein the control tag is inserted in response to detecting a characteristic of the second audio signal.
12. The method of claim 9 , wherein the control tag is inserted in response to receiving a user input.
13. The method of claim 9 , further comprising, in response to detecting the control tag in the portion of the internet radio stream, inserting a third audio signal in the internet radio stream at the content replacement point.
14. The method of claim 9 , further comprising:
selecting a third audio signal based on user demographic information; and
inserting the third audio signal in the internet radio stream at the content replacement point.
15. The method of claim 6 , wherein the second audio signal includes content associated with a broadcast region of the terrestrial radio station.
16. The method of claim 6 , further comprising:
generating a first internet radio stream by inserting a third audio signal in the internet radio stream; and
sending the first internet radio stream to a first user device.
17. The method of claim 16 , further comprising:
generating a second internet radio stream by inserting a fourth audio signal in the internet radio stream; and
sending the second internet radio stream to a second user device.
18. The method of claim 6 , wherein the first source includes at least one of a first microphone, a first traffic report, a first phone call, a first satellite transmission, a first music source, or a first advertising source, and wherein the second source includes at least one of a second microphone, a second traffic report, a second phone call, a second satellite transmission, a second music source, or a second advertising source.
19. A computer-readable storage device storing instructions that, when executed by a processor, cause the processor to perform operations comprising:
generating a portion of a terrestrial broadcast stream, the portion of the terrestrial broadcast stream including a first audio signal from a first source and a second audio signal from a second source, wherein a first segment of the first audio signal overlaps a second segment of the second audio signal;
generating a portion of an internet radio stream corresponding to the portion of the terrestrial broadcast stream, the portion of the internet radio stream including the first segment of the first audio signal and omitting the second audio signal;
sending the portion of the terrestrial broadcast stream to a terrestrial radio station; and
sending the portion of the internet radio stream to a content replacer.
20. The computer-readable storage device of claim 19 , wherein the portion of the internet radio stream is sent to the content replacer to initiate insertion of a third audio signal in the internet radio stream, the internet radio stream provided to a content distribution network.
