本実施形態に係るレコーダ装置の構成について、図1を参照しつつ以下に説明する。図1は、レコーダ装置100の要部構成を示すブロック図である。
チューナー部210は、アンテナ部において受信したデジタル放送波(例えば、BSデジタル放送、CSデジタル放送、地上波デジタル放送)から、映像データ、音声データなどが多重化されているストリーム(Transport Stream:TS)を抽出する。
ストリーム処理部230は、抽出されたストリームまたはエンコードされたストリームに多重化されている映像データ、音声データなどの個々のデータを分離、抽出すると共に、同じパケット識別子(PID)が付与されているパケット(TS)のペイロード部を繋ぎ合わせることにより、コンテンツデータ(PESパケット)を復元する。また、不図示の通信部によりネットワークを介して入力されるコンテンツデータもストリーム処理部230において処理される。
バックエンド制御部240は、レコーダ装置100におけるコンテンツデータの記録および再生全般を制御する。
デコーダ部260は、バックエンド制御部240からの指示を受けて、バッファ部250に格納されているコンテンツデータのうち、バックエンド部200内において生成されるクロック(System Time Clock:STC)の値に一致するタイムスタンプ(PTS)が付与されているコンテンツデータを読み出す。そして読み出したコンテンツデータをデコードし、画像処理部270に出力する。
画像処理部270は、フレームレート変換などのような動画像データの表示性能を向上させるため、画素の補間や色調整などの高品質化処理を実行し、高品質化処理を施した動画像データを表示装置(図示しない)に対して出力する。すなわち、画像処理部270では、デコーダ部260においてデコード(復号)されたフレーム画像から表示装置において実際に表示する際に用いるフレーム画像を生成する。
記憶部280には、バックエンド制御部240を動作させるためのプログラム、および、バックエンド制御部240が参照する各種データが格納されている。バックエンド制御部240により参照されるデータとしては、予約情報およびタイトル管理情報などが挙げられる。予約情報およびタイトル管理情報の詳細については以下に詳述するため、ここではその説明を省略する。なお、記憶部280は、電源をオフにしても記録内容の消去されない不揮発性メモリであることが好ましい。
インターフェース部290は、入力されたデータをインターフェース部310を介してドライブ部300に対して出力する。インターフェース部290としては、SATA(Serial AT attachment)などを挙げることができる。なお、ATA(AT attachment)は、転送方式がシリアルのATAであるSATAに限定されるものではなく、転送方式がパラレルのATAであるPATAを用いてもよい。
ドライブ制御部320は、ディスクドライブ部330に装填されている光ディスクからのデータの読み出し、および光ディスクへのデータの書き込みを制御すると共に、記憶部340からのデータの読み出し、および記憶部340へのデータの書き込みを制御する。
ディスクドライブ部330は、ドライブ制御部320からの指示に基づいて動作し、装填されている光ディスクからのデータの読み出し、または光ディスクに対するデータの書き込みを実行する。
記憶部340は、レコーダ装置100において光ディスクに対して記録するコンテンツデータなどのデータを記憶するデータメモリである。記憶部340におけるコンテンツデータの記録については、下記に詳述するため、ここではその説明を省略する。
次に、レコーダ装置100の再生動作、録画動作、ダビング動作などについて説明するが、これらのレコーダ装置100における各動作の説明に先立って、レコーダ装置100における事前設定について、図2の(a)および(b)および図3の(a)および(b)を参照して説明する。レコーダ装置100における事前設定は、記憶部340の初期化処理と、記憶部340に対する光ディスクの登録処理の2つに大別することができる。

レコーダ装置100は、上述したように自装置において予約登録する以外にも、他装置においてマイディスクに記録された予約情報を取得することにより予約登録を実行することもできる。
次に、記憶部280の予約情報管理領域に記録されている予約情報に含まれているメディアIDのマイディスクがドライブ部300に装填されている場合の録画処理について、図5の(a)および(b)を参照しつつ以下に説明する。図5の(a)および(b)は、マイディスクが装填されている状態での録画処理を示す図であり、(a)は録画処理後の記憶部340およびマイディスク1の状態を模式的に示した図であり、(b)は録画処理後の記憶部280の状態を模式的に示した図である。
続いて、記憶部280の予約情報管理領域に記録されている予約情報に含まれているメディアIDのマイディスクがドライブ部300に装填されていない場合の録画処理について、図7の(a)および(b)を参照しつつ以下に説明する。図7の(a)および(b)は、レコーダ装置100においてマイディスクが装填されていない状態での録画処理を示す図であり、(a)は録画処理後の記憶部340の状態を模式的に示した図であり、(b)は録画処理後の記憶部280の状態を模式的に示した図である。
次に、記憶部340に記録されたコンテンツであってマイディスクに対して記録されていないコンテンツを、マイディスクに対して記録する同期処理について、図9~図11の(a)~(c)を参照して以下に説明する。
記憶部340における領域1の空き容量が少なくなった場合には、領域1に記録されているコンテンツを削除するようにすればよい。領域1に記録されているコンテンツの削除は、ユーザーの指示により実行されるようにしてもよいし、領域1における空き容量が所定値以下となった場合に自動的に実行されるようにしてもよい。
次に、レコーダ装置100におけるコンテンツの再生動作について、図14~図17を参照しつつ以下に説明する。
マイディスクが装填されている場合の再生処理について、図14および図15を参照して以下に説明する。図14は、コンテンツ1~3を記録したディスク1が装填されている場合の記憶部340および記憶部280の状態を示す図である。図15は、マイディスクが装填されている場合において、再生時にコンテンツが読み出される媒体を模式的に示した図である。
続いて、マイディスクが装填されていない場合の再生処理について、図16および図17を参照して以下に説明する。図16は、ドライブ部300に光ディスクが装填されていない場合の記憶部340および記憶部280の状態を示す図である。図17は、マイディスクが装填されていない場合において、再生時にコンテンツが読み出される媒体を模式的に示した図である。

次に、レコーダ装置100におけるコンテンツのコピー動作について、図20の(a)および(b)を参照しつつ以下に説明する。ここでは、レコーダ装置100における記憶部340内のメモリ内コピー動作を例に挙げて説明する。なお、メモリ内コピー動作とは、レコーダ装置100におけるメモリ内ダビング動作と言い換えることもできる。図20の(a)および(b)は、レコーダ装置100におけるメモリ内コピー処理を示す図であり、(a)は、メモリ内コピー処理後の記憶部340の状態を示す図であり、(b)はメモリ内コピー処理後の記憶部280におけるタイトル管理領域の状態を示す図である。
次に、マイディスクの登録解除処理について説明する。ユーザーからのディスク1の登録解除指示を受けたドライブ制御部320は、記憶部340において記録されている、登録を解除するディスク1に対応付けられた領域を管理する管理情報を消去する。すなわち、エントリにおけるメディアID情報、メディアキー情報およびマップ情報を削除すると共に、割り当てフラグを、割り当てが行われていないことを示す「0」に変更する。また、領域にデータが記録されている場合には、記録されているデータも消去する。これによって、記憶部340におけるエントリは、新たなマイディスクの登録が可能な状態となる。
レコーダ装置100では、マイディスクとして登録されている光ディスクへのデータの書き込みおよび光ディスクからのデータの読み出しには、マイディスクとして登録されている光ディスクから取得したファイルシステムを用いることが好ましい。
最後に、レコーダ装置100に接続された表示装置におけるコンテンツとタイトルリストに記録されている情報との表示例について、図22を参照しつつ以下に説明する。図22は、表示装置500上でのコンテンツおよびタイトルリストに記録されている情報の表示を概略的に示す図である。
次に、レコーダ装置100における同期処理の対象となるコンテンツの判定方法の詳細について図23を参照しつつ以下に説明する。図23は、レコーダ装置100における同期処理の詳細を示すフローチャートである。なお、以下の実施形態において記憶部280に記録されている情報および記憶部340に記録されているコンテンツは、装填されているマイディスクに対応する記憶部280の領域および記憶部340の領域から読み出すものとする。
以上説明したように、レコーダ装置100では、記憶部280に記録されている予約情報と、装填されているマイディスクに記録されている予約情報とが一致するか否かを判定することにより、同期処理するべきコンテンツを検出している。
ここで、上述した同期処理の前後での予約情報およびコンテンツの状態を図24および図25を参照しつつ以下に説明する。図24および図25は、レコーダ装置100における同期処理の前後での予約情報およびコンテンツの状態を示す図であり、図24は同期処理前の状態であり、図25は同期処理後の状態である。以下、同期処理前後における予約情報およびコンテンツの記録状態の変化について、ケース毎に分類して説明する。なお、図24および図25は便宜上示していないが、予約情報は記憶部280に記録されており、コンテンツは記憶部340に記録されている。また、図24および図25では、説明の便宜上、ディスク1に関連付けられた予約管理領域に記録されている予約情報のみを図示している。
まず、レコーダ装置100に記録されている予約情報に一致する予約情報がディスク1に記録されており、かつ、その予約情報の指定するコンテンツがレコーダ装置100に記録されている場合について、図24に示す「予約1」を例に挙げて説明する。この場合、レコーダ装置100の記憶部280に「予約1」が記録されており、「予約1」に基づいて録画されたコンテンツである「街歩き」が記憶部340に記録されている。
次に、レコーダ装置100に記録されている予約情報に一致する予約情報がディスク1に記録されていないが、その予約情報の指定するコンテンツがレコーダ装置100に記録されている場合について、図24に示す「予約2」を例に挙げて説明する。この場合、レコーダ装置100の記憶部280に「予約2」が記録されており、「予約2」に基づいて録画されたコンテンツである「世界の車窓」が記憶部340に記録されている。しかし、図24に示すように、「予約2」はディスク1に記録されていない。ただし、ディスク1には「世界の車窓」が記録されている。
続いて、レコーダ装置100に記録されている予約情報に一致する予約情報がディスク1に記録されているが、その予約情報の指定するコンテンツがレコーダ装置100に記録されていない場合について、図24に示す「予約3」を例に挙げて説明する。ここで、「予約3」において設定されている録画予定日時は過去の日時であるものとする。
最後に、レコーダ装置100に記録されている予約情報に一致する予約情報がディスク1に記録されておらず、その予約情報の指定するコンテンツがディスク1に記録されていない場合について、図24に示す「予約4」を例に挙げて説明する。この場合、レコーダ装置100の記憶部280に「予約4」が記録されているが、ディスク1には「予約4」および「予約4」の指定するコンテンツである「番組紹介」が記録されていない。
上述した同期処理は、単一回の録画予約を実行する予約情報に基づいて記録されたコンテンツの処理である。ここで、単一回の録画予約を実行する予約情報とは異なり、スケジュール予約を実行する予約情報により記録されたコンテンツを同期処理する場合について以下に説明する。
まず、レコーダ装置100におけるバックエンド制御部240が、記憶部280に記録されているスケジュール予約のうち、予約Aを選択した場合の同期処理を説明する。
