【発明の属する技術分野】
この発明は放送系番組受信記録再生装置に係わり、特に、ランダムアクセス可能な記録媒体に番組および番組情報を記録可能な受信機に好適な放送系番組受信記録再生装置に関する。
【0002】
【従来の技術】
放送系の番組をランダムアクセス可能な記録媒体に記録するホームサーバにおいて、記録番組の収録時間や残りの記録可能な時間を直観的に分かりやすくするように、再生に要する時間や追加記録可能な時間を利用者の視聴状況に応じて表示面積の大小で表すようにした放送系番組受信記録再生装置が特開2001−111929に提案されている。
【0003】
図5に上記特開2001−111929に提案された放送系番組受信記録再生装置の構成を示す。図に示すアンテナ1により番組情報と番組自体の信号が受信され、図示していないチューナで復調した後、リモートコントローラ(以下リモコンと称する)の各種スイッチ11の一つである録画開始スイッチを押した場合に番組情報は番組情報記録手段3がDVD等の記録媒体に記録し、また番組自体は番組記録手段2がMPEG(Moving Picture Experts Group) 2方式で圧縮してDVD等の記録媒体に記録する。
【0004】
表示制御手段7はリモコンの各種スイッチ11の命令に従って、現在時刻を時計からなる時刻取得手段6から取得し、番組情報記録手段3から記録済み番組の番組表を取得し、番組記録手段2から記録番組を取得する。そして、夫々のデータから記録番組再生手段4を用いて記録番組を再生し、再生時間長算出手段16を用いて再生に要する時間長を算出し、追加書き込み可能時間算出手段5を用いて追加書き込み可能時間を算出して、放送系番組受信記録再生装置本体の表示装置10に表示・制御する。
【0005】
但し、記録番組再生手段4は、記録されたMPEG2形式の圧縮データを伸張する専用ハードウエアで、再生計時記憶手段12を用いて再生視聴したい時間を管理し、番組情報記録手段3内に視聴管理ファイルを削成・更新する。さらに、表示制御手段7はリモコンの各種スイッチ11の命令に従って、指定された番組情報の記録を記録番組情報削除手段9により削除させ、指定された番組の記録を記録番組削除手段8により削除させる。そして、この装置では、追加記録可能な時間の計算は、記録媒体の残り容量と時間あたりに要する平均的な記憶容量との商で求めている。残り再生時間は番組再生時間と、再生済み時間との差により求めている。
【0006】
【発明が解決しようとする課題】
上記した従来の装置では残り再生時間の計算において、再生済み時間が考慮されている。しかしながら、再生手段が倍速再生のような記録媒体の再生時間を増減させる機能を有する場合に対する対応がなされていない。そのため、残り再生時間の計算において、実際の視聴状況に合致しない場合が発生するという問題があった。
【0007】
この発明は上記した点に鑑みてなされたものであって、その目的とするところは、記録された番組を速度の異なる複数の方式で再生する場合に対応して夫々の再生時間を表示する表示手段を備えた放送系番組受信記録再生装置を提供することにある。
【0008】
【課題を解決するための手段】
この発明の放送系番組受信記録再生装置は、放送系の番組および番組情報を受信する受信手段と、前記受信した番組および番組情報を夫々記録する番組記録手段および番組情報記録手段と、前記記録された番組情報を再生する番組情報再生手段と、前記記録された番組を速度の異なる複数の方式で再生する番組再生手段と、現在時刻情報を得る時計と、前記記録された番組を夫々の方式で再生する再生時間を夫々算出する再生時間長算出手段と、前記番組情報記録手段から取得した特定の番組情報より得られた再生方式または前記再生方式と異なる再生方式により再生時間長算出手段を特定する再生時間算出法選択手段と、前記再生時間算出法選択手段で選択された再生時間長算出手段により算出した前記特定の番組情報の番組の再生時間を表示する表示手段とを備え、さらに、番組の視聴予約する番組予約手段と、記録された番組の再生を予約する再生予約手段とを備え、予約された視聴番組の視聴時刻と予約した番組の再生時刻が重なるときは、再生する速度を変えて前記視聴時刻と再生時刻とが重ならなくなる場合に表示手段にそれを表示するものである。
