ダイレクトモード動きベクトルの導出方法

Japanese Patent JP4625104

B2

Using a method of calculation for direct mode motion vectors of a B (Bi-predictive) picture in a moving picture coding system to extract the direct mode motion vectors of the B picture comprises of a co-located block in a list 1 reference picture for direct mode has two motion vectors, selecting any one (a list 0 motion vector or list 1 motion vector) of the two motion vectors, and deriving the direct mode motion vectors of the B picture from the selected motion vector. An independent claim is included for a method of calculation of direct mode motion vectors from a B picture that is temporally closer to the list 1 reference picture.
