The present invention relates to a method to find wanted media material (11) in a media stream (A) comprising wanted (12) and unwanted (13a, 13b) media material. A selected search key (14) is a representation of a part of the wanted media material (11). The search is performed by searching for the search key (14) in the media stream (A), by selecting a first segment (11A1) of the media stream (A) that contains the search key (14), by selecting at least one second segment (11A2, 11A3) of the media stream (A) that contain the search key (14), and by comparing the first segment (11A1) with the second segment (11A2). A common segment (11A12) between the first and second segment (11A1, 11A2) is decided to be the wanted media material (11'). The present invention specifically teaches that the search for the wanted media material is performed in a digitally encoded domain of the media stream (A). |
