【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、記録された所望の番組を簡単な操作で再生できる放送系番組受信記録再生装置に関する。
【0002】
【従来の技術】
従来の放送系番組受信装置により番組を受信してVTR等で録画する場合は、録画した番組の番組名等は使用者が機器を操作して直接入力していた。また、入力できる番組の情報もごく僅かしかなかった。
【0003】
【発明が解決しようとする課題】
上記した従来の装置では番組を記録する場合に録画する番組名等の入力が非常に面倒であった。また、録画した番組が多くなると、視聴したい番組を探すのに手間がかかっていた。
【0004】
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、記録する番組の番組情報が自動的に入力され、視聴したい番組の検索を容易に行うことができる放送系番組受信記録再生装置を提供することにある。
【0005】
【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を再生する記録番組再生手段と、前記番組情報記録手段により記録された番組情報を検索する検索手段とを備え、前記検索手段により検索した情報により番組および番組情報を前記番組記録手段および番組情報記録手段により予約して記録し、前記検索手段により記録された番組情報を検索して再生する番組を指定するものである。
【0006】
また、前記放送系番組受信記録再生装置において、前記番組情報および番組の記録中に番組情報の構成情報が更新される毎に前記番組情報記録手段によりその構成情報を記録し、前記検索手段により前記記録された構成情報を検索して再生する番組を指定するものである。
【0007】
【発明の実施の形態】
この発明の実施例である放送系番組受信記録再生装置を図面に基づいて説明する。図1はこの発明の実施例である放送系番組受信記録再生装置を示すブロック図である。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または予約録画の開始時刻となったとき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。
【0008】
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、表示装置10に画像を表示させ、また、音声を出力させる。
【0009】
表示制御手段7はさらに、各種スイッチ11により指定された予約番組と番組情報について、時刻取得手段6から取得した時間情報を参照して予約番組開始時間となると録画を開始させ、終了時間で録画を終了させる。表示制御手段7は、また、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。
【0010】
なお、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ある。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。なお、記録番組情報および記録番組の削除は録画番組インデックスにおいて消去する番組が記録されている場所を新たに録画可能場所に指定することにより行われる。
【0011】
消去することが指定された場所は、例えば、ランダムアクセス可能な記録媒体であれば細切れになった空きスペースに1つの番組を録画することができる。その場合は、使用しているすべての空きスペースの場所をデータベースに記録しておく。
【0012】
表示制御手段7は、また、記録時間長算出手段12に指令して番組情報であるEPG(電子番組ガイド)を参照して予約する番組の記録時間を算出させる。表示制御手段7は、さらに、各種スイッチ11から入力された情報により、番組情報記録手段3で記録した記録済み番組の番組表から所望の番組を検索する。
【0013】
次に、図2により録画の予約の動作に付いて説明する。録画予約をする場合、先ず、ステップS1において、使用者がEPGにより予約したい番組を選択する。次に、ステップS2において、録画用記録媒体の空き容量を調べ、さらに、ステップS3において、ステップS3で調べた空き容量が録画に必要な量あるか否かを判断し、必要な量ある場合は、ステップS4に移行し、ない場合は、ステップS5に移行する。ステップS4では予約された番組を記録する領域を確保してこのルーチンを終了する。ステップS5では予約する番組を記録する空き容量がないことを表示装置10に表示してこのルーチンを終了する。
【0014】
次に、図3により録画番組のインデックデータベースの作成動作に付いて説明する。ステップS11において、番組の録画が始まると、番組の録画を行いながらステップS12において、EPGを定期的に取得する。そして、ステップS13において、EPGに含まれる当該番組に関する情報が更新されているか否かを調べる。更新されている場合はステップS14に移行し、更新されていない場合はステップS15に移行する。
【0015】
ステップS14では、更新された番組に関する情報を番組情報記録手段3によりデータベースに保存し、ステップS15に移行する。ステップS15では番組が終了したか否かを判断し、終了した場合はこの動作を終了させ、終了していない場合は他の動作を行い所定時間が経過する毎に、ステップS12以下を繰り返す。
【0016】
このように録画番組に関する情報をEPGから取得し、録画番組インデックスデータベースに保存するので、録画番組を視聴する際に、そのデータベースを使用して、視聴したいものを検索することができる。
【0017】
また、EPGに番組の構成情報が含まれている場合に、それをデータベースに保存しておけば、番組の先頭からだけでなく、途中から視聴を開始することもできる。番組の構成情報とは例えば次のようなものである。
【0018】
番組: 紅白歌合戦
構成情報:
19:00〜21:00 ヤングの部
21:00〜21:10 応援等
21:10〜23: アダルトの部
上の例では『アダルトの部』から視聴を開始したりすることができる。
【0019】
【発明の効果】
この発明の放送系番組受信記録再生装置によれば、録画した番組の番組名等が自動的に記録されるので、手動で番組名等を入力する必要がなくなる。また、ジャンル、出演者等で検索して視聴する番組を指定することが可能となる。さらに、連続ドラマを連続して再生することもできる。
