Description
モジュール72は、更にパーソナルコンピュータ22、24、26及び30からの受信データをケーブルヘッドエンド32へ送信するために変調する。
同軸ケーブル94は、コンバイナ84によって生成された第2の結合された信号をテレビジョン14及びパーソナルコンピュータ24へ送信する。同軸ケーブル96は、コンバイナ86によって生成された第3の統合された信号をテレビジョン16及びパーソナルコンピュータ26へ送信する。同軸ケーブル100は、コンバイナ90によって生成された第4の統合された信号をテレビジョン20及びパーソナルコンピュータ30へ送信する。
アナログとデジタル映像を統合することによって、このベースバンド信号をダイプレックスフィルター等のスプリッターで分離し、10Base-Tやユニバーサルシリアルバス(USB)等のより一般的な様式に対応するよう変換することができる。
この場合、MVDU10は、ケーブルヘッドエンド32からダウンロードされる映像を保存するためのデータ記憶装置112を有する。
記憶された映像をテレビジョンセット12、14、16及び20でそれぞれ再生するために、どのリモートコントロール端末62、64、66及び70を使用しても選択することができる。
この場合、MVDU210は、ケーブルヘッドエンド32からダウンロードされる映像を保存するためのデータ記憶装置312を有する。記憶された映像をテレビジョンセット212、214、216及び220でそれぞれ再生するために、どのリモートコントロール端末262、264、266及び270を使用しても選択することができる。PVR(Personal Video Recorder)機能の詳細は、図1に関して示されたものと類似する。
