Abstract:
1. A commercial-break detection device for the detection of commercial-break information present in picture information of a television signal, having detection means arranged to receive the television signal and adapted to detect black-frame information in the picture information of the television signal, and having memory means for the storage of black-frame time information for each one of at least two units of detected black-frame information, and having analysis means for analyzing the stored black-frame time information and for determining commercial-break position information identifying the commercial-break information in the picture information, wherein the detection means is adapted to detect a fade-out, in which fade-out a luminance signal of the picture information decreases during a fade-out time until the picture information is formed by the black-frame information, and the detection means are adapted to determine fade black-frame time information and edge black-frame time information, the fade black-frame time information identifying black-frame information which is directly preceded by a fade-out, and the edge black-frame time information identifying black-frame information which is not directly preceded by a fade-out, and the analysis means are adapted to separately analyze the stored fade black-frame time information and the stored edge black-frame time information, in order to determine the commercial-break position information.
