Abstract
The present invention relates to an apparatus and method for identifying music in a content, The present invention includes extracting and storing a fingerprint of an original audio in an audio fingerprint DB; extracting a first fingerprint of a first audio in the content; and searching for a fingerprint corresponding to the fingerprint of the first audio in the audio fingerprint DB, wherein the first audio is audio data in a music section detected from the content.
Claims14
A method for identifying music in a content, the method comprising:
- extracting and storing a fingerprint of an original audio comprising synthesized audio in an audio fingerprint database (DB);
- extracting a fingerprint of a first audio in the content;
- and
- searching for a fingerprint corresponding to the fingerprint of the first audio in the audio fingerprint DB,
- wherein the first audio is audio data in a music section detected from the content,
- wherein extracting and storing the fingerprint of the original audio in the audio fingerprint DB comprises:
- extracting the fingerprint of the original audio;
- resynthesizing the original audio after separating a music signal and a non-music signal of the original audio, wherein the resynthesizing comprises synthesizing by amplifying the music signal and by attenuating the non-music signal;
- and
- extracting a fingerprint of the resynthesized original audio, and
- wherein the fingerprint of the original audio is mapped with the fingerprint of the resynthesized original audio in the audio fingerprint DB.
An apparatus for identifying music in a content, the apparatus comprising:
- a memory configured to store data;
- and
- a processor configured to control the memory,
- wherein the processor is further configured to:
- extract and store a fingerprint of an original audio comprising synthesized audio in an audio fingerprint database (DB),
- extract a fingerprint of a first audio in the content, and
- search for a fingerprint corresponding to the fingerprint of the first audio in the audio fingerprint DB,
- wherein the first audio is audio data in a music section detected from the content, and
- wherein the processor is further configured to:
- extract the fingerprint of the original audio;
- resynthesize the original audio after separating a music signal and a non-music signal of the original audio by amplifying the music signal and attenuating the non-music signal;
- and
- extract a fingerprint of the resynthesized original audio, and
- wherein the processor is further configured to map the fingerprint of the original audio with the fingerprint of the resynthesized original audio.
A computer program stored in a non-transitory computer-readable medium, the computer program implementing in a computer:
- extracting and storing a fingerprint of an original audio comprising synthesized audio in an audio fingerprint database (DB);
- extracting a fingerprint of a first audio in a content;
- and
- searching for a fingerprint corresponding to the fingerprint of the first audio in the audio fingerprint DB,
- wherein the first audio is audio data in a music section detected from the content,
- wherein extracting and storing the fingerprint of the original audio in the audio fingerprint DB comprises:
- extracting the fingerprint of the original audio;
- resynthesizing the original audio after separating a music signal and a non-music signal of the original audio, wherein the resynthesizing comprises synthesizing by amplifying the music signal and by attenuating the non-music signal;
- and
- extracting a fingerprint of the resynthesized original audio, and
- wherein the fingerprint of the original audio is mapped with the fingerprint of the resynthesized original audio in the audio fingerprint DB.
