Abstract
【解決手段】デコーダは、第1合成装置と、第2合成装置と、デブロックフィルタとを有する。第1合成装置は、デブロック処理をせず、表示用の再構成アップサンプリングベースレイヤピクチャの形成のため、フル解像度動き補償予測と復号済みアップサンプリングベースレイヤ残差とを合成する。第2合成装置は、第1合成装置と通信し、再構成フル解像度エンハンスメントレイヤピクチャを形成するため、再構成アップサンプリングベースレイヤピクチャと復号済みエンハンスメントレイヤ残差とを合成する。デブロックフィルタは、第2合成装置と通信し、表示用フィルタリングされた復号済みフル解像度エンハンスメントレイヤピクチャを出力するため、再構成フル解像度エンハンスメントレイヤピクチャだけにデブロック処理を実行する。
