Audio event triggers for broadcast
View Patent ↗Information associated with a broadcast stream event is encoded within an in-band broadcast. The encoded information in a broadcast stream is detected. The detected information is decoded at least in part to determine content to be injected into the broadcast stream.
1. A method, comprising:
encoding information associated with a broadcast stream event within an in-band broadcast;
detecting the encoded information in a broadcast stream; and
decoding the detected information at least in part to determine content to be injected into the broadcast stream, wherein:
the broadcast stream is a linear radio broadcast for at least one of the following: AM radio, FM radio, and HD radio; and
the in-band broadcast originates at least in part from a play-out system for a linear radio broadcast station.
2. The method of claim 1 , wherein the encoding is modulated at least in part to reduce human perceptibility of the encoded information by a consumer of the broadcast stream.
3. The method of claim 2 , wherein the modulation comprises upshifting frequency.
4. The method of claim 2 , wherein the modulation comprises upshifting frequency to center frequencies higher than 1633 Hz.
5. The method of claim 2 , wherein the modulation comprises upshifting frequency of DTMF encoded characters.
6. The method of claim 2 , wherein the modulation comprises reducing amplitude.
7. The method of claim 2 , wherein the modulation comprises reducing amplitude to levels far below normal broadcast levels.
8. The method of claim 2 , wherein the modulation comprises downshifting frequency.
9. The method of claim 2 , wherein the modulation comprises downshifting frequency of GMSK modulated data.
10. The method of claim 2 , wherein the modulation comprises use of multi-frequency signaling using a mixture of three or more tones.
11. The method of claim 2 , wherein the modulation is a digital modulation, comprising one or more of the following: ASK, APSK, CPM, FSK, MFSK, MSK, OOK, PPM, PSK, QAM, I/Q modulation, SC-FDE, and TCM.
12. The method of claim 2 , wherein the modulation is an analog modulation, comprising one or more of the following: AM, FM, PM, QAM, SM, and SSB.
13. The method of claim 2 , wherein the modulation is a spread spectrum, comprising one or more of the following: CSS, DSSS, FHSS, and THSS.
14. The method of claim 2 , wherein the modulation includes error detection techniques.
15. The method of claim 2 , wherein the modulation includes error correction techniques.
16. The method of claim 2 , wherein the broadcast stream event comprises a service and a duration.
17. The method of claim 1 , wherein the modulated encoding is stored as a recording.
18. The method of claim 1 , further comprising receiving an indication to trigger the broadcast stream event from a play out system.
19. The method of claim 1 , wherein the broadcast comprises one or more of the following: a radio broadcast, a television broadcast, movie broadcast, sports broadcast, satellite broadcast, and cable broadcast.
20. The method of claim 1 , further comprising inserting real time ads.
21. The method of claim 20 , wherein the real time ads are inserted from a cloud platform.
22. The method of claim 21 , further comprising providing real time compliance data.
23. A system, comprising:
an encoder configured to encode information associated with a broadcast stream event within an in-band broadcast; and
a receiver coupled to a broadcast stream, wherein the receiver is configured to:
detect the encoded information in the broadcast stream; and
decode the detected information at least in part to map the decoded information to content to be injected into the broadcast stream, wherein:
the broadcast stream is a linear radio broadcast for at least one of the following: AM radio, FM radio, and HD radio; and
the in-band broadcast originates at least in part from a play-out system for a linear radio broadcast station.
24. A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:
encoding information associated with a broadcast stream event within an in-band broadcast;
detecting the encoded information in a broadcast stream; and
decoding the detected information at least in part to map the decoded information to content to be injected into the broadcast stream, wherein:
the broadcast stream is a linear radio broadcast for at least one of the following: AM radio, FM radio, and HD radio; and
the in-band broadcast originates at least in part from a play-out system for a linear radio broadcast station.
