図3の(F)および図4の(F)に示すように、ダイレクトモードの list 1 レファランスピクチャにある同位置のマクロブロックは、レファランスピクチャの時間的位置に関わらずイントラモードを持つことができる。このようなモードを有するマクロブロックは動き情報を持っていないため、従来手法では単にダイレクトモード動きベクトルを0とし、 list 0 レファランスピクチャは最近にデコーディングされたピクチャと定義した。しかし、従来手法は高いコーディング効率が保障できなかったため、本発明ではBピクチャのコーディングしようとするマクロブロックの周辺ブロックから list 0 、 list 1 レファランスピクチャと各 list に対する動きベクトルを空間的冗長性を用いて予測し、算出する。
ケース1:Bピクチャのマクロブロックと list 1 レファランスピクチャの同一位置にあるマクロブロックの両方ともフレームモードのとき
MVF = TDB×MV/TDD
MVB = (TDB - TDD)×MV/TDD
Z = TDB×256/TDD MVF = (Z×MV + 128)>>8
W = Z - 256 MVB = (W×MV + 128)>>8
MVF = -TDB×MV/TDD
MVB = -(TDB + TDD)×MV/TDD
Z = -TDB×256/TDD MVF = (Z×MV + 128)>>8
W = Z - 256 MVB = (W×MV + 128)>>8
図7では、Bピクチャのマクロブロックと list 1 レファランスピクチャの同一位置にあるマクロブロックの両方ともフィールドモードの場合を示す。Bピクチャのマクロブロックの各ブロックにおける動きベクトルは同一パリティの list 1 レファランスフィールドにある同一位置の list 0 動きベクトルから誘導される。
MVF,i = TDB,i×MVi/TDD,i
MVB,i = (TDB,i - TDD,i)×MVi/TDD,i
Z = TDB,i×256/TDD,i MVF,i = (Z×MVi + 128)>>8

Z = -TDB,i×256/TDD MVF,i = (Z×MV + 128)>>8
W = Z - 256 MVB,i = (W×MV + 128)>>8
図9は、Bピクチャのマクロブロックがフレームモードであり、 list 1 レファランスピクチャの同一位置にあるマクロブロックがフィールドモードの場合を示す。ここで、現在マクロブロックの垂直座標をycurrentとし、 list 1 レファランスピクチャの同位置のマクロブロック垂直座標をyco-locatedとすれば、両座標の間にはyco-located=ycurrent/2の関係が成り立つ。そして、 list 1 基準フレームのフィールド0がフィールド1よりBピクチャに時間的距離が近いので、フィールド0にある同一位置のブロックの動き情報がダイレクトモードの動きベクトルを求めるのに使用される。
MVF = TDB×MV0 /TDD,0
MVB = (TDB - TDD,0 )×MV0 /TDD,0
前記式は、下記のように表すことができる。
Z = TDB×256/TDD,0 MVF = (Z×MV0 + 128)>>8
W = Z - 256 MVB = (W×MV0 + 128)>>8
MVF = -TDB×MV0 /TDD,0
MVB = -(TDB + TDD,0 )×MV0 /TDD,0

この場合には list 0 、 list 1 レファランスピクチャのいずれもBピクチャより常に時間的に前に位置している。
図4に示すように、 list 1 レファランスピクチャの同一位置にあるブロックは一つの動きベクトルを持つか、二つの動きベクトルを持つことができる。本発明では、同一位置のブロックが二つの動きベクトルを持つ場合には一つの動きベクトル(L0 MVまたはL1 MV)を選び、この選ばれた動きベクトルからダイレクトモードの動きベクトルを誘導する(以下では、L0 MV( list 0 動きベクトル)が選ばれた場合を基準に説明するものとする)。

仮に、ダイレクトモードの list 0 レファランスピクチャが list 1 レファランスピクチャより時間的に前に存在する場合、Bフレームの各フィールドiに対するダイレクトモードの list 0 、 list 1 動きベクトルMVF,i、MVB,iは下記のように計算される(図11の(A)および(B))。

MVF,i=TDB,i×MV/TDD
MVB,i = (TDB,i - TDD)×MV/TDD
前記式は下記のように表すことができる。
Z = TDB,i×256/TDD MVF,i = (Z×MV + 128)>>8
W = Z - 256 MVB,i = (W×MV + 128)>>8
MVF,i = -TDB,i×MV/TDD
MVB,i = -(TDB,i + TDD)×MV/TDD

前記ダイレクトモードの list 1 レファランスピクチャがBピクチャより時間的に前に位置するか、または後に位置する場合、各ケースに対して2種類の数式が存在することになるので、これを単純化するための方法でピクチャ間の時間的距離を符号付きの値で表すと、下記のように単純化して表される。

Bピクチャのマクロブロックがフレームモードであり、 list 1 レファランスピクチャの同一位置にあるマクロブロックがフィールドモードであり、 list 1 レファランスピクチャが前記Bピクチャより時間的に後に存在する場合、 list 1 基準フレームのフィールド0がフィールド1よりBピクチャに時間的距離が近いので、フィールド0にある同一位置のブロックの動き情報がダイレクトモードの動きベクトルを求めるのに使用される。したがって、前記Bフレームのダイレクトモードの動きベクトルMVF、MVBは、 list 1 基準フレームのフィールド0にある同一位置のブロックの動き情報がダイレクトモードの動きベクトルを求めるのに使用される下記の式から求めることができる。
MVF = TDB×MV0 /TDD,0
MVB = (TDB - TDD,0 )×MV0 /TDD,0
または、
Z = TDB×256/TDD,0 MVF = (Z×MV0 + 128)>>8
W = Z - 256 MVB = (W×MV0 + 128)>>8
MVF = TDB×MV1/TDD,1
MVB = (TDB - TDD,1)×MV1/TDD,1
または、
Z = TDB×256/TDD,1 MVF = (Z×MV1 + 128)>>8
W = Z - 256 MVB = (W×MV1 + 128)>>8
