Abstract

　MPEG-2 AAC、MPEG-Surroundまたは(AAC+SBR)では、受信したビットストリームの中身を最後まで解析しないとAACかMPSかの判別ができないため、音声信号の出力遅延が大きくなると、映像信号の出力を遅らせる制御が間に合わず、AV同期がとれないという課題がある。 　送信装置は、音声ストリームパケットのヘッダ情報には含まれない情報で、音声符号化信号の復号時間が予め定められた復号時間を超える要因となる処理が含まれるか否かを示す符号化情報を含み、受信装置により音声ストリームパケットの復号開始前に解析されるデータパケットを生成するデータパケット生成手段と、音声ストリームパケット、データパケットおよび映像ストリームパケットを多重化放送により送信する送信手段とを備える。受信装置では、符号化信号の中身を最後まで解析せずに、符号化方式特有の情報を知ることができる。
