Control signals in streaming audio or video indicating a watermark
Methods and apparatuses for searching for a control signal in streaming video or streaming audio that indicates the presence of a watermark in the streaming video or streaming audio. The streaming video or streaming audio is received and searched for a control signal. The detection of a control signal indicates the presences of a digital watermark in the streaming video or streaming audio. An indicator is triggered based upon detecting the control signal.
1. A method comprising:
receiving streaming video or streaming audio;
searching, using a processor, the streaming video or the streaming audio for a control signal, wherein the control signal indicates a presence of a digital watermark in the streaming video or the streaming audio; and
triggering an indicator based upon detecting the control signal.
2. The method of claim 1 , further comprising initiating decoding of the digital watermark in response to detecting the control signal.
3. The method of claim 1 , wherein the indicator comprises a visual icon.
4. The method of claim 3 , further comprising:
receiving a selection of the visual icon; and
initiating decoding of the digital watermark based in part upon the receipt of the selection of the visual icon.
5. The method of claim 1 , wherein the watermark comprises a multi-bit payload, and wherein the multi-bit payload comprises the control signal and an object identifier.
6. The method of claim 5 , further comprising accessing information based in part upon the object identifier.
7. The method of claim 5 , further comprising taking an action based in part upon the object identifier.
8. The method of claim 1 , wherein the indicator comprises audio data.
9. A system comprising:
a processor configured to:
receive streaming video or streaming audio;
search the streaming video or the streaming audio for a control signal, wherein the control signal indicates a presence of a digital watermark in the streaming video or the streaming audio; and
trigger an indicator based upon the control signal.
10. The system of claim 9 , wherein the processor is further configured to initiate decoding of the digital watermark in response to detecting the control signal.
11. The system of claim 9 , further comprising a display configured to display the indicator, wherein the indicator comprises a visual icon.
12. The system of claim 11 , wherein the processor is further configured to:
receive a selection of the visual icon; and
initiate decoding of the digital watermark based in part upon the receipt of the selection of the visual icon.
13. The system of claim 9 , wherein the watermark comprises a multi-bit payload, and wherein the multi-bit payload comprises the control signal and an object identifier.
14. The system of claim 13 , wherein the processor is further configured to access information based in part upon the object identifier.
15. The system of claim 13 , wherein the processor is further configured to take an action based in part upon the object identifier.
16. The system of claim 9 , further comprising a speaker to produce sound based upon the indicator, wherein the indicator comprises audio data.
17. A tangible computer-readable medium having instructions stored thereon, the instructions comprising:
instructions to receive streaming video or streaming audio;
instructions to search the streaming video or the streaming audio for a control signal, wherein the control signal indicates a presences of a digital watermark in the streaming video or the streaming audio; and
instructions to trigger an indicator based upon the control signal.
18. The tangible computer-readable medium of claim 17 , further comprising instructions to initiate decoding of the digital watermark in response to detecting the control signal.
19. The tangible computer-readable medium of claim 17 , further comprising:
instructions to receive a selection of a visual icon, wherein the indicator comprises the visual icon; and
instructions to initiate decoding of the digital watermark based in part upon the receipt of the selection of the visual icon.
20. The tangible computer-readable medium of claim 17 , further comprising instructions to take an action based in part on an object identifier, wherein the watermark comprises a multi-bit payload, and wherein the multi-bit payload comprises the control signal and the object identifier.
