Method for increasing the functionality of a media player/recorder device or an application program
A method is provided for utilizing a title signal contained in digital data through a comparison of the title signal to a player signal stored in a player device.
1. A method comprising:
receiving audio or video data, at a player device, via a communications connection, wherein the audio or video data includes a digital watermark that encodes a device ID and a reference to a remote database from which additional data related to the audio or video data can be retrieved;
decoding, at the player device, the watermark to extract the device ID and the reference to the remote database;
determining to restrict playback of the audio or video data based at least on the device ID;
playing back the audio or video data, by the player device, based on the determination; and
retrieving, using the reference to the remote database, the additional data from the remote database.
2. The method of claim 1 , wherein the digital watermark further encodes a use restriction corresponding to the audio or video data.
3. The method of claim 1 , further comprising:
comparing the digital watermark to an identifier of the player device; and
performing an operation, by the player device, based on the comparison.
4. The method of claim 3 , wherein the operation comprises at least one of usage-control of the audio or video data or device-control of the player device.
5. The method of claim 3 , wherein the identifier comprises at least one of a serial number or a registered owner.
6. The method of claim 1 , wherein the digital watermark further encodes a copy protection payload having a number of bits, and wherein the device ID is a portion of the watermark unused by the payload.
7. The method of claim 1 , wherein the digital watermark is included in the audio or video data such that the digital watermark varies throughout at least a portion of the audio or video data.
8. The method of claim 1 , wherein restricting playback comprises degrading playback of the audio or video data.
9. The method of claim 1 , wherein the reference to the remote database comprises a unique identifier key corresponding to a record of the remote database.
10. The method of claim 1 , wherein the reference to the remote database comprises a URL of the remote database.
11. The method of claim 1 , further comprising adding a playback effect to the audio or video data based on a playback parameter for the audio or video data, wherein the watermark further encodes the playback parameter, and wherein the playback effect includes at least one of applying an equalization of the audio data, applying an echo to the audio data, applying a reverb to the audio data, and adjusting a color space of the video data.
12. A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising:
instructions to receive audio or video data, at a player device, via a communications connection, wherein the audio or video data includes a digital watermark that encodes a device ID and a reference to a remote database from which additional data related to the audio or video data can be retrieved;
instructions to decode, at the player device, the watermark to extract the device ID and the reference to the remote database;
instructions to determine whether to restrict playback of the audio or video data based at least on the device ID;
instructions to play back the audio or video data, by the player device, based on the determination; and
instructions to retrieve, using the reference to the remote database, the additional data from the remote database.
13. The non-transitory computer-readable medium of claim 12 , wherein the digital watermark further encodes a use restriction corresponding to the audio or video data.
14. The non-transitory computer-readable medium of claim 12 , further comprising:
instructions to compare the digital watermark to an identifier of the player device; and
instructions to perform an operation, by the player device, based on the comparison.
15. The non-transitory computer-readable medium of claim 14 , wherein the operation comprises at least one of usage-control of the audio or video data or device-control of the player device.
16. The non-transitory computer-readable medium of claim 14 , wherein the identifier comprises a serial number or a registered owner.
17. The non-transitory computer-readable medium of claim 12 , wherein the digital watermark further encodes a copy protection payload having a number of bits, and wherein the device ID is a portion of the watermark unused by the payload.
18. The non-transitory computer-readable medium of claim 12 , wherein the digital watermark is included in the audio or video data such that the digital watermark varies throughout at least a portion of the audio or video data.
19. The non-transitory computer-readable medium of claim 12 , wherein restricting playback comprises degrading playback of the audio or video data.
20. An apparatus comprising:
a player device configured to:
receive audio or video data, via a communications connection, wherein the audio or video data includes a digital watermark that encodes a device ID and a reference to a remote database from which additional data related to the audio or video data can be retrieved;
decode the watermark to extract the device ID and the reference to the remote database;
determine whether to restrict playback of the audio or video data based at least on the device ID;
play back the audio or video data based on the determination; and
retrieve, using the reference to the remote database, the additional data from the remote database.
21. The apparatus of claim 20 , wherein the digital watermark further encodes a use restriction corresponding to the audio or video data.
22. The apparatus of claim 20 , wherein the player device is further configured to:
compare the digital watermark to an identifier of the player device; and
perform an operation, by the player device, based on the comparison.
23. The apparatus of claim 22 , wherein the operation comprises at least one of usage-control of the audio or video data or device-control of the player device.
24. The apparatus of claim 22 , wherein the identifier comprises a serial number or a registered owner.
25. The apparatus of claim 20 , wherein the digital watermark further encodes a copy protection payload having a number of bits, and wherein the device ID is a portion of the watermark unused by the payload.
26. The apparatus of claim 20 , wherein the digital watermark is included in the audio or video data such that the digital watermark varies throughout at least a portion of the audio or video data.
27. The apparatus of claim 20 , wherein restricting playback comprises degrading playback of the audio or video data.
