Abstract:
1. A moving picture coding method of coding a current block which is included in a current picture by performing temporal prediction using a co-located block which is included in a coded picture, the co-located block having two reference motion vectors, the two reference motion vectors being two motion vectors calculated with reference to one or more pictures located before the current picture in display order, said moving picture coding method comprising: coding the current block using a first motion vector and a second motion vector, respectively, with reference to a first reference picture list and a second reference picture list; generating a first predictive motion vector and a second predictive motion vector; and coding the first motion vector and the second motion vector, respectively, using the first predictive motion vector and the second predictive motion vector, wherein (i) when any reference pictures in the first reference picture list and the second reference picture list are located before the current picture in display order, (ii) when a reference picture in the first reference picture list and the second reference picture list are not located before the current picture in display order, and the first reference motion vector and the second reference motion vector refer to different directions,
