Description
Definition)映像のような高解像度、高品質な映像への需要が、多様な応用分野において増加しつつある。映像データが高解像度、高品質になるほど既存の映像データに比べて相対的にデータ量が増加するため、既存の有無線の広帯域ネットワークのような媒体を用いて映像データを伝送するか、既存の記憶媒体を用いて記憶する場合、伝送コストと記憶コストが増加する。映像データが高解像度、高品質化になることで発生するこのような問題を解決するためには、高効率の映像圧縮技術が活用されることができる。
search−based Block Matching Algorithm)、TSS(Three Step Search)、NTS(New Three−Step
Search Algorithm)など多様な方法が使用されることができる。動きベクトルは、補間された画素に基づいて1/2または1/4画素単位の動きベクトル値を持つことができる。動き予測部では、動き予測方法を異ならせて現在予測単位を予測することができる。動き予測方法として、スキップ(Skip)法、マージ(Merge)法、AMVP(Advanced Motion Vector Prediction)法など多様な方法が使用されることができる。
Coding Unit)内の位置によって適応的に決定されることができる。以下、本発明における予測部の動作に関して詳述する。
