Method and system for remotely controlling consumer electronic devices
A media system replaces content in a first sequence of media content. The media system presents the first sequence of media content to an end-user and generates a fingerprint of the sequence of media content. The fingerprint is for comparison with a plurality of reference fingerprints so as to identify the first sequence of media content and determine a reference position within the first sequence of media content. The media system sends a request for a replacement sequence of content to a content replacement system, and receives replacement media content selected based on the identified first sequence of media content. The media system presents the replacement media content to the end-user instead of the first sequence of media content. Presenting the replacement media content begins at a position in the first sequence of media content that is determined based on the reference position.
1. A method comprising:
receiving, at a media system, a sequence of media content from a media content distributor over a communication network, the sequence of media content including steganographic data;
outputting, by the media system, the sequence of media content for presentation; and
while outputting the sequence of media content for presentation, (i) detecting, by the media system, the steganographic data in the sequence of media content and (ii) responsive to detecting the steganographic data in the sequence of media content, invoking, by the media system, an application on the media system,
wherein the steganographic data is encrypted, the method further comprising decrypting the steganographic data.

The method of claim 1 , wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises, in response to detecting the steganographic data in the sequence of media content, beginning to record the sequence of media content.
4. The method of claim 1 , wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises, in response to detecting the steganographic data in the sequence of media content, invoking an interactive program.
5. The method of claim 4 , wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises, in response to detecting the steganographic data in the sequence of media content, causing presentation on a display of the media system of an interactive element in conjunction with presentation of the sequence of media content.
6. The method of claim 5 , wherein the interactive element comprises a selectable object.
7. The method of claim 5 , wherein causing presentation of the interactive element comprises causing presentation of an overlay.
8. The method of claim 1 , wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises invoking the application based on presence of the detected steganographic data in the sequence of media content.
9. The method of claim 1 , further comprising extracting the steganographic data from the sequence of media content, wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises invoking the application based on content of the detected steganographic data in the sequence of media content.
10. The method of claim 1 , wherein the steganographic data is encoded inside of a transport layer.
11. The method of claim 1 , wherein the sequence of media content comprises a sequence of video content, and wherein detecting the steganographic data in the sequence of media content comprises detecting an adjusted chrominance of a pixel of the sequence of media content.
12. The method of claim 1 , wherein the sequence of media content comprises an audio signal, and wherein the steganographic data comprises data steganographically encoded in the audio signal.
13. A media system comprising:
one or more processors;
memory;
a display; and
instructions stored in the memory and executable by the one or more processors to cause the media system to carry out operations including:
receiving a sequence of media content from a media content distributor over a communication network, the sequence of media content including steganographic data,
outputting the sequence of media content for presentation on the display, and
while outputting the sequence of media content for presentation on the display, (i) detecting the steganographic data in the sequence of media content and (ii) responsive to detecting the steganographic data in the sequence of media content, invoking an application on the media system,
wherein the steganographic data is encrypted, the operations further including decrypting the steganographic data.
14. The media system of claim 13 , wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises, in response to detecting the steganographic data in the sequence of media content, beginning to record a program on a digital video recorder.
15. The media system of claim 13 , wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises, in response to detecting the steganographic data in the sequence of media content, invoking an interactive program.
16. The media system of claim 13 , wherein the operations further include extracting the steganographic data from the sequence of media content, and wherein invoking the application on the media system responsive to detecting the steganographic data in the sequence of media content comprises invoking the application based on content of the extracted steganographic data.
17. The media system of claim 13 , wherein the steganographic data is encoded inside of a transport layer.
18. The media system of claim 13 , wherein detecting the steganographic data in the sequence of media content comprises detecting an adjusted chrominance of a pixel of the sequence of media content.
19. A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors of a media system, cause the media system to carry out operations comprising:
receiving a sequence of media content from a media content distributor over a communication network, the sequence of media content including steganographic data,
outputting the sequence of media content for presentation on the display, and
while outputting the sequence of media content for presentation on the display, (i) detecting the steganographic data in the sequence of media content and (ii) responsive to detecting the steganographic data in the sequence of media content, invoking an application on the media system,
wherein the steganographic data is encrypted, the operations further comprising decrypting the steganographic data.
