Abstract:
According to exemplary embodiments of the present invention, references to a motion vector in a neighboring block of an enhancement layer or in a block of a previously coded picture, and a motion vector of a base layer are equally handled. Accordingly, a motion_prediction_flag with identification information can be integrated for further improved coding efficiency.
