Abstract
記録媒体に予め記録されているデータと、ネットワークを介してダウンロードしたデータを同期して再生する際に、複数のダウンロードデータを同時に使用することが考慮されておらず、記録媒体からの再生データとの同期再生が困難だったという課題を解決すること。
【解決手段】
入力端子105から入力されたストリームを一時記憶するバッファメモリ106と、バッファメモリ106から出力されたパケットをパケット識別番号にしたがって分別するデマルチプレクサ107と、入力端子101から入力されたストリームを一時記憶するバッファメモリ103a〜dと、デマルチプレクサ107から出力されたパケットとバッファメモリ103a〜dから出力されたパケットのどちらかを切り替えスイッチ104a〜dより選択して出力するパケット切り替え器100をデータ再生に用いる。
【選択図】 図1
Description
