Patent ID: 7593850

Claim:
A method for receiving media signals ( 1 ) through receiving means, said media signals ( 1 ) containing unwanted signal components; to choose a representation for said media signals and to process these media signals ( 1 ) in such a way that said unwanted signal components are essentially removed and the remaining signal components are saved, said method comprising the steps of: from the media signals ( 1 ) choosing a first search key representation ( 20 ); in a search track ( 30 ), conducting a first search to find a signal representation ( 10 ) that contains a section ( 11 ) which is essentially identical with said first search key representation ( 20 ); comparing a first segment ( 40 ), which lies before and after said search key ( 20 ), with a second segment ( 41 ) which lies before and after said section ( 11 ) which is essentially identical with the first search key representation ( 20 ); from said first segment ( 40 ) and said second segment ( 41 ) finding a first common segment ( 44 ); loading said common segment ( 44 ) into a memory domain; and storing said common segment ( 44 ) in said memory domain as a signal representation ( 70 ) without unwanted signal components.
