Summary: | PROBLEM TO BE SOLVED: To provide an encoding method and a device that encodes a digital video content.SOLUTION: An encoding method includes the steps of: dividing a picture into a plurality of small parts; selecting the plurality of small parts together at a time in a frame encoding mode, and selecting the plurality of small parts together at a time in a field encoding mode; and deriving two relative reference pictures or fields indicated with at least two motion vectors and two motion vectors of a current block of a small part of the plurality of small parts, and encoding the selected small parts when a picture is a bidirectional prediction encoded picture, the small parts having a size which is a multiple above 1 of a macro block, and each current block of a current block of the small part having a size smaller than the small part.SELECTED DRAWING: Figure 11
【課題】デジタルビデオコンテンツを符号化する符号化方法及び装置を提供する。【解決手段】ピクチャを複数の小さい部分に分割するステップと、複数の小さい部分をフレーム符号化モードに一度に選択し、及び複数の小さい部分をフィールド符号化モードに一度に選択するステップと、ピクチャが両方向予測符号化ピクチャである場合、少なくとも二つの動きベクトルと、複数の小さい部分の小さい部分の現在のブロックの二つの動きベクトルに指し示される二つの関連する参照ピクチャまたはフィールドを導出することを含む、選択された小さい部分を符号化するステップとを有し、小さい部分はマクロブロックの1より上の倍数であるサイズを有し、小さい部分の現在のブロックの各現在のブロックは、小さい部分よりも小さいサイズを有することを特徴とする符号化方法。【選択図】図11 |
