Abstract

　デジタルテレビジョン放送の番組の符号化ビデオデータストリームを復号化することにより得られた復号化ビデオデータストリームに対して符号化処理を行う画像符号化処理であって、前記復号化ビデオデータストリームに対して解像度に応じた符号化処理を行うビデオエンコード処理と、前記復号化ビデオデータストリームにおける解像度の変化を検出する変化位置検出処理とを備え、前記変化位置検出処理において解像度の変化が検出された場合に、前記ビデオエンコード処理において、当該変化前の解像度に応じた符号化処理を停止して当該変化後の解像度に応じた符号化処理を開始し、前記復号化ビデオデータストリームの当該変化の直前の部分と直後の部分とを互いに独立した異なるＧＯＰとして符号化処理を行う。
