Abstract
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 Analysis
Total Claims: 8
Claim 1
Independent Claim
115 words
A mobile station comprising: a processor; a user input mechanism for causing the processor to extract a plurality of features from a digital media sample, said features being descriptive of an identity of a content of said media sample; and a transmitter coupled to said processor, wherein a single user input at the input mechanism causes the processor to extract the plurality of features and to initiate a wireless link to a network, wherein the single user input causes the transmitter to transmit over the initiated wireless link a message comprising the plurality of features extracted from the digital media sample, wherein the message carries insufficient information from which to reconstruct the digital media sample.
Claim 2
Dependent Claim
115 words
A mobile station comprising: a processor; a user input mechanism for causing the processor to extract a plurality of features from a digital media sample, said features being descriptive of an identity of a content of said media sample; and a transmitter coupled to said processor, wherein a single user input at the input mechanism causes the processor to extract the plurality of features and to initiate a wireless link to a network, wherein the single user input causes the transmitter to transmit over the initiated wireless link a message comprising the plurality of features extracted from the digital media sample, wherein the message carries insufficient information from which to reconstruct the digital media sample.
Claim 3
Dependent Claim
90 words
A mobile station comprising: a transducer to receive an analog media sample; a processor to derive a digital media sample from the analog media sample; a buffer memory, disposed between said transducer and said processor, to temporarily store at least a portion of the digital media sample; and a user input mechanism for causing the processor to extract at least one feature from at least the portion that is temporarily stored in the buffer memory, wherein the feature is descriptive of an identity of a content of said media sample.
Claim 4
Dependent Claim
90 words
A mobile station comprising: a transducer to receive an analog media sample; a processor to derive a digital media sample from the analog media sample; a buffer memory, disposed between said transducer and said processor, to temporarily store at least a portion of the digital media sample; and a user input mechanism for causing the processor to extract at least one feature from at least the portion that is temporarily stored in the buffer memory, wherein the feature is descriptive of an identity of a content of said media sample.
Claim 5
Dependent Claim
31 words
The mobile station of claim 2 wherein said user input mechanism is for causing the buffer to so temporarily store and the processor to so extract upon a single user input.
Claim 6
Dependent Claim
40 words
The mobile station of claim 2 further comprising: means to receive the digital media sample from which the processor extracts the at least one feature, and a display interface to display a symbol corresponding to the derived digital media sample.
Claim 7
Dependent Claim
129 words
A mobile station comprising: a processor; a user input mechanism for causing the processor to extract at least one feature from a digital media sample, said feature being descriptive of an identity of a content of said media sample; means to receive a first digital media sample; a display interface to display a symbol corresponding to the first digital media sample; and a transducer to receive and convert an analog media sample to a second digital media sample, wherein the user input mechanism is for causing the processor to extract at least one feature from the first digital media sample when the displayed symbol is selected by a user of the mobile station, and from the second digital media sample when no displayed symbol is selected by the user.
Claim 8
Dependent Claim
129 words
A mobile station comprising: a processor; a user input mechanism for causing the processor to extract at least one feature from a digital media sample, said feature being descriptive of an identity of a content of said media sample; means to receive a first digital media sample; a display interface to display a symbol corresponding to the first digital media sample; and a transducer to receive and convert an analog media sample to a second digital media sample, wherein the user input mechanism is for causing the processor to extract at least one feature from the first digital media sample when the displayed symbol is selected by a user of the mobile station, and from the second digital media sample when no displayed symbol is selected by the user.
