A method and device for detecting commercials using the encoding parameters of a compressed video stream is provided. A video encoder receives uncompressed video data and generates a compressed video data. A plurality of separators, each defined by at least two consecutive scene changes in a sequence of the compressed video data, is detected. Then, the beginning and ending of a commercial break is derived by comparing the gap between these separators to a predetermined threshold value. |
