Abstract
Description
光学的記憶媒体は、1つまたは複数のビデオおよびオーディオのデータストリームおよび/または別のデータを含む音響映像(AV)信号を記録または再生することができる。前記別のデータは、たとえば字幕およびサービス情報等である。www.dvdforum.orgによって広められたデジタル多用途ディスク(DVD)標準規格に基づいて、事前記録された映画タイトルは、読み出し専用の光学的ディスクを使用して量販市場向けに複製される。赤色レーザを基礎とするDVD標準規格の導入および拡大に続いて、青色レーザを基礎とする、ますます大きな容量の媒体システムが、「Blu‐ray」という商標名で広まってきている。これは、BDと表示される。
本発明は、以下の事実の認識に基づく。すべての有効なコンポーネントを含むAVマルチプレクスを有する場合、たとえば別のサウンドトラックまたは別のウェブページ等の付加的なマテリアルを後で提供することはできない。すなわち、コンテンツプロバイダが制作ツールを使用して、BD映画を生成する場合、すべての要素ストリームを把握してから生成を開始しなければならない。AVマルチプレクスを製作した後に別の要素ストリームを追加することはできない。また、別のデータストリームを後で追加しなければならない場合、既存のデータストリームと同期する必要がある。
本発明の実施例を、添付図面を参照して説明する。この図面は、異なるビデオストリームパスとオーディオストリームパスと字幕ストリームパスとを含む再生リストの一例を示している。
図1は、異なるビデオストリームパスと、オーディオストリームパスと、字幕ストリームパスとを含む再生リストList_of_PlayItemsの一例を示している。この再生リストはPlayItemまたはSubPlayItemを有し、これをデコードしてストリームパスを再生しなければならない。PlayItemの第1のストリームパスはAV多重ストリームを有している。さらに幾つかのSubPlayItemによって、上記のオーディオストリームパスと、ビデオストリームパスと、字幕ストリームパスとが記述される。
事前記録されたBlu‐rayディスクの作成におけるフレキシビリティが向上される。たとえば、メインのAVマルチプレクスが完成した後に、付加的な言語を後の時点でディスクに容易に追加することができる。これは、たとえば他言語のオーディオ情報および字幕情報を含む補助的なAVマルチプレクスを別個に作成し、基本的なAVマルチプレクスを変更せずに(記録、再多重化する必要なく)該補助的なAVマルチプレクスをディスクイメージに追加できるからだ。
Claims (8)
- データストリームを同期するための方法であって、
該データストリームは、ビデオデータおよび/またはオーディオデータおよび/または別のデータを含んでおり、
該データストリームのうち幾つかは、基本的なデータストリームマルチプレクスで記憶媒体に事前記録されており、
ナビゲーションファイル(List_of_PlayItems)は、データストリームの各部分をポインティングする記述子(PlayItem,SubPlayItem)を含んでおり、
前記記述子によってデータストリームの時間的な配列を、データサブストリームパスによって定義することを特徴とする方法。 - 該データストリームのうち幾つかは、記憶媒体上の基本的なAVデータストリームマルチプレクスの外部に位置付けられている、請求項1記載の方法。
- 前記記述子は、時間的な相互関係に関するコンポーネントの同期を定義する、請求項1または2記載の方法。
- 別個のコンポーネントの開始時点および終了時点を定義する、請求項3記載の方法。
- 前記記述子は、スイッチングに関するコンポーネントの同期を定義する、請求項1または2記載の方法。
- 1つのコンポーネントのデコードを別のコンポーネントのデコードに置換できる、時間またはバイナリストリームにおけるポイントを定義する、請求項5記載の方法。
- PlayItemおよびSubPlayItemのデータストリームの形式は、MPEG搬送ストリームであり、
SubPlayItemのデータストリームはプログラム割り当てテーブルを含んでおらず、PlayItemのデータストリーム内で使用されていないPIDを有するプログラムマップテーブルを含んでいる、請求項1から5までのいずれか1項記載の方法。 - 請求項1から6までのいずれか1項記載の方法を実施するための装置。
