摘要： A decoding section generates a decoded image and a coding parameter set from a first video coded video sequence. A coding parameter set conversion section first sets the coding structure for a pair of upper and lower macro blocks based on the coding structures of the corresponding macro blocks and converts the remaining parameters such as a motion vector based on the coding structure. A coding parameter set generation section generates coding parameters of an intraframe coding parameter, etc., a coding parameter set selection section selects an optimum parameter set, and a coding section performs recoding processing.

摘要： A fade detection unit performs fade detection, and in a case where a judgment of fade-in has been made, an encoding control unit notifies a motion detection unit to perform encoding in a reverse order to a display order. The fade detection unit performs the fade detection, and in the case where the judgment of the fade-in or fade-out has been made, the encoding control unit notifies the motion detection unit to perform encoding while importance is attached to a prediction from an image having a larger information amount in a B picture.
