Methods for collecting media segments in a media signal via comparing segments of the signal to later segments
First Claim
1. 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.

Abstract
A method to achieve signals which are essentially devoid of unwanted signal components uses a search and comparison process. Media signals are received through receiving means, the media signals containing unwanted signal components, a representation for the media signals is chosen, and the media signals are processed in such a way that the unwanted signal components are essentially removed and the remaining signal components are saved. The method includes the steps of: from the media signals, choosing a search key representation; in a search track, conducting a first search after a signal representation that contains a section which is essentially identical with the search key; comparing a first segment, which lies before and after the search key, with a second segment which lies before and after the section, which is essentially identical with the first search key; from said first segment and the second segment, finding a common segment; and storing the common segment in the memory domain as a signal representation without unwanted signal components.
