Embedding and reading codes on objects
View Patent ↗The disclosure relates generally to audio and video signal processing. One claim recites a method comprising: receiving audio or video content, wherein the audio or video content comprises a hidden steganographic code including information, the steganographic code being hidden in the audio or video content through alterations to data representing the audio or video content; detecting the steganographic code to obtain the information, said act of detecting utilizes correlation to obtain the information; providing at least a portion of the information to a data repository to identify machine-executable instructions stored therein; providing data associated with a user to the data repository; receiving machine-executable instructions from the data repository; and executing the machine-executable instructions to control processing of the audio or video content. Of course, other claims and combinations are provided too.
1. A method comprising:
receiving audio or video content, wherein the audio or video content comprises a hidden steganographic code including information, the steganographic code being hidden in the audio or video content through alterations to data representing the audio or video content;
detecting the steganographic code to obtain the information, said act of detecting utilizes correlation to obtain the information;
providing at least a portion of the information to a data repository to identify machine-executable instructions stored therein;
providing data associated with a user to the data repository;
receiving machine-executable instructions from the data repository; and
executing the machine-executable instructions to control processing of the audio or video content.
2. The method of claim 1 wherein executing the machine-executable instructions processes the audio or video content as part of inventory or distribution management.
3. The method of claim 1 wherein executing the machine-executable instructions processes the audio or video content as part of audio or video identification.
4. The method of claim 1 wherein executing the machine-executable instructions processes the audio or video content as part of a purchase of the audio or video content.
5. The method of claim 1 further comprising receiving information or instructions from the data repository in response to the data associated with the user.
6. A computing apparatus programmed to perform the method of claim 1 .
7. An apparatus comprising:
means for receiving audio or video content, wherein the audio or video content comprises a hidden steganographic code including information, the steganographic code being hidden in the audio or video content through alterations to data representing the audio or video content;
means for detecting the steganographic code to obtain the information, said detecting utilizes correlation to detect and obtain the information;
means for providing at least a portion of the information to a data repository to identify machine-executable instructions stored therein;
means for providing data associated with a user to the data repository;
means for receiving machine-executable instructions from the data repository; and
means for executing the machine-executable instructions to control processing of the audio or video content.
8. The apparatus of claim 7 in which said means for executing the machine-executable instructions processes the audio or video content as part of inventory or distribution management.
9. The apparatus of claim 7 in which said means for executing the machine-executable instructions processes the audio or video content as part of audio or video identification.
10. The apparatus of claim 7 in which said means for executing the machine-executable instructions processes the audio or video content as part of a purchase of the audio or video content.
11. The apparatus of claim 7 further comprising means for receiving information or instructions from the data repository in response to the data associated with the user.
