Abstract
【解決手段】構文解析回路307は、記憶装置302からのシーン記述子SDに含まれているURLを抽出し、そのURLに対応するエレメンタリストリームESとオブジェクトストリーム情報IOを記憶装置306,305にそれぞれ出力する。OD発生回路304は、情報OIからオブジェクト記述子ODを抽出し、そのID番号OD_ID
を生成して、BIFSエンコーダ308に供給するとともに、オブジェクト記述子ODに付与して多重化回路303に出力する。多重化回路303は、BIFSエンコーダ308においてバイナリフォーマットに変換された、ID番号OD_IDが含まれるシ
ーン記述子SDと、オブジェクト記述子ODと、エレメンタリストリームESとを多重化し、多重化ストリームFSとして出力する。
