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;
presenting, by the media system, the sequence of media content; and
while presenting the sequence of media content, (i) detecting, by the media system, the steganographic data in the sequence of media content and (ii) in response to detecting the steganographic data in the sequence of media content, presenting, by the media system, a message,
wherein the steganographic data is encrypted, the method further comprising decrypting the steganographic data.
2. The method of claim 1 , wherein presenting by the media system a message in response to detecting by the media system the steganographic data in the sequence of media content comprises presenting by the media system a prerecorded video message in response to detecting by the media system the steganographic data in the sequence of media content.
3. The method of claim 1 , wherein presenting by the media system a message in response to detecting by the media system the steganographic data in the sequence of media content comprises presenting by the media system an “unauthorized access” message in response to detecting by the media system the steganographic data in the sequence of media content.
4. The method of claim 1 , wherein presenting by the media system a message in response to detecting by the media system the steganographic data in the sequence of media content comprises presenting by the media system caller-identification information for a voice-over-IP telephone service.
5. The method of claim 1 , wherein the media system comprises a display, and wherein presenting the message comprises displaying the message.
6. The method of claim 1 , further comprising extracting the steganographic data from the sequence of media content.
7. The method of claim 1 , wherein presenting the message in response to detecting steganographic data in the sequence of media content comprises presenting the message based on content of the detected steganographic data in the sequence of media content.
8. The method of claim 1 , wherein the steganographic data is encoded inside of a transport layer.
9. 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.
10. 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.
11. 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,
presenting the sequence of media content on the display, and
while presenting the sequence of media content on the display, (i) detecting the steganographic data in the sequence of media content and (ii) in response to detecting the steganographic data in the sequence of media content, presenting a message on the display,
wherein the steganographic data is encrypted, the operations further including decrypting the steganographic data.
12. The media system of claim 11 , wherein presenting a message on the display in response to detecting the steganographic data in the sequence of media content comprises presenting a prerecorded video message on the display in response to detecting the steganographic data in the sequence of media content.
13. The media system of claim 11 , wherein presenting a message on the display in response to detecting the steganographic data in the sequence of media content comprises presenting an “unauthorized access” message on the display in response to detecting the steganographic data in the sequence of media content.
14. The media system of claim 11 , wherein presenting a message on the display in response to detecting the steganographic data in the sequence of media content comprises presenting, on the display, caller-identification information for a voice-over-IP telephone service.
15. The media system of claim 11 , 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.
16. 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,
presenting the sequence of media content on a display of the media system, and
while presenting the sequence of media content on the display, (i) detecting the steganographic data in the sequence of media content and (ii) in response to detecting the steganographic data in the sequence of media content, presenting a message on the display,
wherein the steganographic data is encrypted, the operations further comprising decrypting the steganographic data.
17. The non-transitory computer-readable medium of claim 16 , wherein presenting a message on the display in response to detecting the steganographic data in the sequence of media content comprises presenting a prerecorded video message on the display in response to detecting the steganographic data in the sequence of media content.
18. The non-transitory computer-readable storage medium of claim 16 , wherein presenting a message on the display in response to detecting the steganographic data in the sequence of media content comprises presenting an “unauthorized access” message on the display in response to detecting the steganographic data in the sequence of media content.
19. The non-transitory computer-readable storage medium of claim 16 , wherein presenting a message on the display in response to detecting the steganographic data in the sequence of media content comprises presenting, on the display, caller-identification information for a voice-over-IP telephone service.
