US 7,221,902 B2 · Mobile station and interface adapted for feature extraction from an input media sample

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.

Dependent claims

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.
