Abstract

　本発明は、デパケタイズ処理における不要な待機時間を低減させ、処理を容易かつ高速に行うことができるようにすることができる情報処理装置および方法に関する。 解析部６２１は、入力された画像データと、記憶部６２２より読み出した１つ前のピクチャの画像データとを比較する。隠蔽用ヘッダ生成部６２３は、その解析結果に基づいて、受信装置６０３がエラー隠蔽処理の際に参照する隠蔽用ヘッダを生成する。ロス解析部６３１は、隠蔽用ヘッダに基づいて、記憶部６３２に記憶されている符号化データを適宜利用しながら、伝送誤りの発生に対してエラー隠蔽を行う。本発明は、例えば、符号化装置に適用することができる。
