20140135964, "Music information searching method and apparatus thereof," assigned to Samsung and Kwangwoon University (KR).
A music information searching method includes extracting modulating spectrums from audio data, generating modulating spectrum peak point audio fingerprints by using position information which relates to preset peak points from the extracted modulating spectrums, converting the generated modulating spectrum peak point audio fingerprints into hash keys which indicate addresses of hash tables and hash values that are stored on the hash tables via hash functions, and searching music information by extracting hash keys which relate to audio query clips and comparing the extracted hash keys with the indicated addresses of the hash tables.
20140133693, "Device and method of inserting watermarks through conversing contents automatically," assigned to SIGONGmedia Co., Ltd. (KR).
Provided are a watermark insertion apparatus and method. The watermark insertion method includes acquiring content through upload by a user, storing the uploaded content, receiving a content conversion request from a user or a manager, determining whether content for which content conversion has been requested is video or an image, converting the content according to the determined content kind, and inserting watermark suitable for the content kind into the converted content.
