Abstract

A mobile station has a processor and a user input mechanism such as a button that is operable to cause the processor to extract at least one feature from a digital media sample. The feature, such as a spectral centroid, is descriptive of an identity of a content of the media sample. Preferably, the same user input that causes the feature extraction also causes a transmitter to establish a link and to send a message to a network address, the message having a plurality of extracted features from which the digital media sample may not be reconstructed. Where a reply message identifies a media file that matches the media sample, another user input at the same or a different button causes an authorization message to be sent so that a copy of the media file, identified in the reply message and having features that exactly match the plurality of extracted and transmitted features, is downloaded to the mobile station.

Claims

1-22. -22. (canceled)

23. A mobile station comprising:

input means for receiving a media file;

a user input mechanism;

a processor configured, responsive to an input at the user input mechanism, to extract from the media file a set of features that quantify characteristics of content of the media file;

a transmitter adapted to wirelessly send to a media file recognition service a message that comprises the extracted set of features.

24. The mobile station of claim 23, wherein each of the set of features comprise MPEG-7 descriptors.

25. The mobile station of claim 23 wherein the processor adaptively selects a number and type of features of the first set to extract based on a type of the media file.

26. The mobile station of claim 25, wherein the adaptive selection comprises M stages of feature extraction, and further wherein the message comprises the extracted set of features and the number M of stages.

27. The mobile station of claim 23, wherein the message does not include a sample from the media file.

28. The mobile station of claim 23, further comprising:

a receiver adapted to receive from the media file recognition service, following the transmitter sending the extracted set of features, an identification message comprising a name of the media file; and

a display screen adapted to automatically display the media file name received in the identification message.

29. The mobile station of claim 28, wherein prior to the receiver receiving the identification message:

the receiver is adapted to receive a request message from the media file recognition service that comprises a list of additional features;

the processor is adapted to, automatically responsive to the request message, to extract a set of additional features from the media file according to the list; and

the transmitter is adapted to wirelessly send to the media file recognition service another message that comprises the extracted additional set of features.

30. The mobile station of claim 28, wherein the identification message further comprises a link from which the media file named in the identification message is available for download.

31. The mobile station of claim 30, wherein the user input mechanism is further adapted such that an additional input at the user input mechanism causes the media file named in the identification message to be wirelessly downloaded to the mobile station.

32. The mobile station of claim 31, wherein the user input mechanism comprises a dedicated button.

33. A mobile station comprising:

media file input means;

user input means;

processing means configured, responsive to an input at the user input mechanism, for extracting from the media file a set of features that quantify characteristics of content of the media file;

transmitting means for wirelessly sending to a media file recognition service a message that comprises the extracted set of features;

receiving means for wirelessly receiving from the media file recognition service an identification message comprising a name of the media file; and

display means for displaying, automatically responsive to the identification message being received, the name of the media file.

34. The mobile station of claim 33, wherein:

the media file input means comprises at least one of a wireless receiver and a microphone;

the user input means comprises at least one of a button, a touch sensitive sensor within the display means, and a microphone adapted for voice recognition;

the processing means comprises a digital processor;

the transmitting means and the receiving means comprise a wireless transceiver; and

the display means comprises a display screen.

35. A method comprising:

receiving a media file;

responsive to a user input, extracting from the received media file a set of features that quantify characteristics of content of the media file; and

wirelessly sending to a media file recognition service a message that comprises the extracted set of features.

36. The method of claim 35, wherein each of the set of features comprise MPEG-7 descriptors.

37. The method of claim 35 wherein extracting comprises determining a type of the media file, and adaptively selecting a number and type of features of the set to extract based on the determined type of the media file.

38. The method of claim 37, wherein adaptively selecting comprises selecting M stages of feature extraction, and further wherein the message comprises the extracted set of features and the number M of stages.

39. The method of claim 35, wherein the message does not include a sample from the media file.

40. The method of claim 35, further comprising, after transmitting:

receiving from the media file recognition service an identification message comprising a name of the media file; and

automatically displaying the media file name received in the identification message.

41. The method of claim 40, further comprising, prior to receiving the identification message:

receiving a request message from the media file recognition service that comprises a list of additional features;

automatically responsive to the request message, extracting a set of additional features from the media file according to the list; and

wirelessly sending to the media file recognition service another message that comprises the extracted additional set of features.

42. The method of claim 40, wherein the identification message further comprises a link from which the media file named in the identification message is available for download, and wherein displaying comprises displaying the media file name and the link.

43. The method of claim 42, further comprising, responsive to an additional user input at the same user input mechanism at which the said user input was received, wirelessly receiving the media file named in the identification message.

44. A program of machine readable instructions, tangibly embodied on an information bearing medium and executable by a digital data processor, to perform actions directed to analyzing a media sample, the actions comprising:

sensing a user input;

responsive to the user input, extracting from a received media file a set of features that quantify characteristics of content of the media file; and

wirelessly sending to a media file recognition service a message that comprises the extracted set of features.

45. The program of claim 44, wherein each of the set of features comprise MPEG-7 descriptors.

46. The program of claim 44 wherein extracting comprises determining a type of the media file, and adaptively selecting a number and type of features of the set to extract based on the determined type of the media file.

47. The program of claim 46, wherein adaptively selecting comprises selecting M stages of feature extraction, and further wherein the message comprises the extracted set of features and the number M of stages.

48. The program of claim 44, wherein the message does not include a sample from the media file.

49. The program of claim 44, wherein the actions further comprise, after transmitting:

receiving from the media file recognition service an identification message comprising a name of the media file; and

automatically displaying the media file name received in the identification message.

50. The program of claim 49, wherein the actions further comprise, prior to receiving the identification message:
