  • Patent number: 8290284
    Abstract: A processing-coefficient decision unit decides a processing coefficient based on a format of the stream. A target-PTS decision unit multiplies an input PTS value by the processing coefficient, to set this as a target PTS used to determine the continuity of the pictures. A reference-PTS calculation unit sets the target PTS as an initial value of a reference PTS, sequentially adds an increment corresponding to the PTS value per picture, and calculates the reference PTS which is compared with the target PTS. A difference calculation unit calculates a difference between the target PTS and the reference PTS. A threshold determination unit compares an absolute value of the difference with the processing coefficient being a threshold and determines whether the absolute value of the difference is less than the processing coefficient.
