Description

ＤＶＤ開始時刻Ｔ_ｖｓおよびＤＶＤ終了時刻Ｔ_ｖｅは、ＤＶＤ画像の再生が開始（ステップＳ６の時刻）および停止（ステップＳ１２の時刻）されたときの時刻を表す。また、メモリスティックファイル名Ｆ_ｍ、メモリスティック開始時刻Ｔ_ｍｓ、およびメモリスティック終了時刻Ｔ_ｍｅは、それぞれメモリスティックから再生された音声のファイルのファイル名、ファイルＦ_ｍの再生が開始された時刻（ステップＳ８の時刻）Ｔ_ｍｓ、および再生が停止された時刻（ステップＳ１０の時刻）Ｔ_ｍｅを表す。そして、リンク開始時刻Ｔ_Ｌｓとリンク終了時刻Ｔ_Ｌｅは、ＤＶＤ画像の再生とメモリスティックの音声がリンクしている（重なっている）ときの開始時刻と終了時刻を表す。シンクロナンバーは、現在設定されている変数ＮＯの値を表す。これらの時刻の具体的な例については、図７と図８を参照して後述する。
【００４３】
ステップＳ１３において、システムコントローラ３６は、入力Ｉ／Ｆ３５を介して操作部３４から、プログラムリハーサルモードの終了の指令を検知したか否かを判定する。
【００４４】
ステップＳ１３において、プログラムリハーサルモードの終了が検知されていないと判定された場合、システムコントローラ３６は、処理をステップＳ１４に進め、変数ｉを１だけ増やす。その後、ステップＳ４乃至ステップＳ１２の処理が繰り返される。従って、次に行われる画像と音声の再生は、シンクロナンバーＮＯ＝２として記憶される。
【００４５】
ステップＳ１３において、プログラムリハーサルモードの終了が検知されたと判定された場合、システムコントローラ３６は、処理をステップＳ１５に進める。
【００４６】
ステップＳ１５において、システムコントローラ３６は、内部のメモリに一時的に記憶しておいた上述のＤＶＤおよびメモリスティックの開始時刻および終了時刻などで構成されるプレイリストを、図５に示される所定のフォーマットで、メモリ３７に記憶する。
【００４７】
図５に示されるフォーマットの第１行目には、ＤＶＤのディスク名とメモリスティック名が記録される。第２行目には、ＤＶＤディスクのファイル名とメモリスティックのファイル名が記録される。
【００４８】
以下、シンクロナンバー毎の情報が記録される。各シンクロナンバーの情報は、ＤＶＤの画像の再生の開始時刻（メインストリーム開始時刻）、ＤＶＤの画像が再生された時間のうち、サブ画面５３で再生されたメモリスティックの音声とシンクロしている期間を示す開始時刻と終了時刻（メインストリームシンクロ開始時刻および終了時刻）、サブ画面５３で行われたメモリスティックの音声の開始時刻と終了時刻（サブストリームシンクロ開始時刻および終了時刻）、並びに、メイン画面５２で行われたＤＶＤの画像の再生が終了した時刻（メインストリーム終了時刻）で構成される。
【００４９】
なお、このうちのメインストリームシンクロ開始時刻と終了時刻、並びにサブストリームシンクロ開始時刻と終了時刻は、上述したリンク位置の時刻Ｔ_Ｌｓ，Ｔ_Ｌｅに対応する。上述のステップＳ４乃至ステップＳ１２の処理が、シンクロナンバー毎に繰り返されると、このシンクロナンバーの構成が、ＮＯ＝１，２，３，・・・，ｎというように、順次、追加される。そして、最終行には、各シンクロナンバー間の順番が記録される。これにより、再生の順番を、シンクロナンバーの順番と異ならせる場合でも、再生の順番を変更するだけで、変更が容易にできるようになされている。このフォーマットの具体的な例は、図７と図８を参照して後述する。
【００５０】
ステップＳ１６において、システムコントローラ３６は、ステップＳ１５で生成したプレイリストを保存するための、保存用のメモリスティックの装着をユーザに要求するメッセージを表示部５１に表示させる。ユーザは、プレイリストを保存するメモリスティックを、音声ファイルが記憶されているメモリスティックとは異なるものにする場合、メモリスティックを変更する。プレイリストを同一のメモリスティックに記録する場合、ユーザは、メモリスティックを変更しない。
【００５１】
プレイリスト保存用のメモリスティックの装着が検知されると、ステップＳ１７において、システムコントローラ３６は、プレイリストを図５で示したフォーマットでメモリスティックに記録する。このときの保存場所は、例えば、図６に示されるように、予め決められた所定の場所（ＲＯＯＴディレクトリの下の、ＣＯＮＴディレクトリ）とされる。勿論、任意の場所をユーザが指定するようにしてもよい。
【００５２】
上述のフローチャートの例では、システムコントローラ３６は、プレイリストを、再生する音声が記録されていたメモリスティック、またはそれとは別の、新たなメモリスティックに記録保存したが、ＤＶＤプレーヤ１のメモリ３７、またはＤＶＤ（光ディスク２）に記録させてもよい。
【００５３】
図７は、図３のプログラムリハーサルモード処理の具体例を示す図である。図７に示される例では、ＤＶＤの時刻ｔ_１乃至ｔ_２の画像が、シンクロナンバーＮＯ＝１として再生され、それと同時に、メモリスティックの時刻ｔ_１２乃至ｔ_１３の音声が再生されている。次に、シンクロナンバーＮＯ＝２として、ＤＶＤの時刻ｔ_５乃至ｔ_８の画像が再生され、そのうちの時刻ｔ_６乃至ｔ_７の時間に、メモリスティックの時刻ｔ_１８乃至ｔ_１９の音声が再生されている。さらに、シンクロナンバーＮＯ＝３として、ＤＶＤの時刻ｔ_４乃至ｔ_５の画像が再生され、それと同時に、メモリスティックの時刻ｔ_１６乃至ｔ_１７の音声が再生されている。最後に、シンクロナンバーＮＯ＝４として、ＤＶＤの時刻ｔ_２乃至ｔ_４の画像が再生され、その間の時刻ｔ_３からｔ_４の時間に、メモリスティックの時刻ｔ_１４乃至ｔ_１５の音声が同時に再生されている。
【００５４】
プログラムリハーサルモードにおいて、このような再生が行われた場合、図８に示されるようなプレイリストが作成、記録される。すなわち、シンクロナンバーＮＯ＝１においては、メインストリーム開始時刻は、ｔ_１、メインストリームシンクロ開始時刻および終了時刻は、ｔ_１およびｔ_２、サブストリームシンクロ開始時刻および終了時刻は、ｔ_１２およびｔ_１３、メインストリーム終了時刻はｔ_２とされる。シンクロナンバーＮＯ＝２においては、メインストリーム開始時刻は、ｔ_５、メインストリームシンクロ開始時刻および終了時刻は、ｔ_６およびｔ_７、サブストリームシンクロ開始時刻および終了時刻は、ｔ_１８およびｔ_１９、メインストリーム終了時刻はｔ_８とされる。
【００５５】
シンクロナンバーＮＯ＝３においては、メインストリーム開始時刻は、ｔ_４、メインストリームシンクロ開始時刻および終了時刻は、ｔ_４およびｔ_５、サブストリームシンクロ開始時刻および終了時刻は、ｔ_１６およびｔ_１７、メインストリーム終了時刻はｔ_５とされる。シンクロナンバーＮＯ＝４においては、メインストリーム開始時刻は、ｔ_２、メインストリームシンクロ開始時刻および終了時刻は、ｔ_３およびｔ_４、サブストリームシンクロ開始時刻および終了時刻は、ｔ_１４およびｔ_１５、メインストリーム終了時刻はｔ_４とされる。シンクロナンバー間の順番は、ＮＯ＝１，２，３，４の後に、ＮＯ＝２，３が再度繰り返されたものとされている。
【００５６】
次に、図９のフローチャートを参照して、メモリスティックに記録されたプレイリストを読み出して再生を行う、プログラム再生シンクロモード処理について説明する。
【００５７】
はじめに、ステップＳ３１において、システムコントローラ３６は、メモリスティックが装着されたことを検知する。そして、システムコントローラ３６は、ステップＳ３２において、ＤＳＰ３１を制御して、メモリスティックの予め決められたディレクトリ（図６の例の場合、ＣＯＮＴディレクトリ）に記録されているプレイリストを読み出す。
【００５８】
プレイリストは、図５に示されるような所定のフォーマットで記録されているので、システムコントローラ３６は、ステップＳ３３において、そのプレイリストに記録されているディスク名とメモリスティック名を、ＤＶＤプレーヤ１に接続されているテレビジョン受像機４の表示部５１に表示する。
【００５９】
その表示を確認したユーザが、表示された名前のディスクとメモリスティックを装着し、再生の開始を指示すると、システムコントローラ３６は、ステップＳ３４において、入力Ｉ／Ｆ３５を介してその再生の指示を検出する。
【００６０】
ステップＳ３５において、システムコントローラ３６は、読み出したプレイリストに従って、ＤＶＤの画像とメモリスティックの音声を同期して再生する。プレイリストの最後まで再生が終了したとき、プログラム再生シンクロモードの処理は終了する。
【００６１】
上述した例では、ＤＶＤに記録された画像とメモリスティック（メモリカード３）に記録された音声を同時に再生する実施の形態について説明したが、以上の例に限らず、ＤＶＤに記録された音声とメモリカード３にＪＰＥＧ（Ｊｏｉｎｔ Ｐｈｏｔｏｇｒａｐｈｉｃ Ｅｘｐｅｒｔ Ｇｒｏｕｐ）などで記録された画像を同時に再生したり、または、ＣＤに記録された音楽とメモリカード３に記録された画像を同時に再生したりすることも可能である。
【００６２】
このようにして、例えば、ＤＶＤ（光ディスク２）に記録されている、自分の好きなタレントが出演している映画の好みのシーンに合わせて、メモリカード３に記録されている好みの曲を再生するようにすると、ユーザは、お気に入りのアルバムを製作することができる。また、メモリカード３に記録されているＪＰＥＧ静止画に同期してＣＤの音楽を再生するようにすると、ユーザは、ＣＤの音楽をＪＰＥＧ静止画に対する好みのバックグラウンドミュージックとすることができる。また、メモリスティックに録音した音声に同期してＤＶＤの映画を再生するようにすると、ユーザは、俳優の声を自分の声に吹き替えたり、違うセリフにすることができる。さらに、カラオケディスクに同期してメモリカードに記録された彼女の歌声を再生するようにすると、ユーザは彼女といつでもデュエットすることができる。
【００６３】
以上では、画像と音声を同時に再生する実施の形態について説明したが、画像と画像を再生（合成）する場合も考えられる。図１０は、そのような場合のＡＶデコーダ２８の構成例を示している。
【００６４】
通常のデコード処理の場合、ＡＶデコーダ２８のデコード部８１は、ＥＣＣ部２６（図２）から入力された画像のデータを、ＤＲＡＭ２９（図２）に必要なデータを記憶させながら、例えばＭＰＥＧ（Ｍｏｖｉｎｇ Ｐｉｃｔｕｒｅ Ｅｘｐｅｒｔｓ Ｇｒｏｕｐ）方式でデコードし、そのデコードの結果得られる、例えば画像データを、ＮＴＳＣ／ＰＡＬエンコーダ３０（図２）に出力する。
【００６５】
一方、画像の合成がなされる場合、システムコントローラ３６（図２）は、入れ替え可能な領域の画像の色を、輝度信号ｙ０，色差信号ｃｂ０，色差信号ｃｒ０として、比較部８２に供給する。比較部８２は、システムコントローラ３６から供給される輝度信号ｙ０，色差信号ｃｂ０，色差信号ｃｒ０と、デコード部８１から入力されるＤＶＤの画像の輝度信号ｙ，色差信号ｃｂ，色差信号ｃｒとを比較し、同じ色であるか否かを判定する。この判定は、対応する色差信号どうしを比較することで行ってもよいし、Ｙ，Ｃｂ，Ｃｒ信号をＲＧＢ信号に変換した後、ＲＧＢ信号を比較することでおこなってもよい。判定結果は、選択部８３に出力される。選択部８３は、比較部８２から供給される判定結果に基づいて、入れ替え可能な画素に位置調整部８４から供給されたＪＰＥＧ画像を入れ替える。位置調整部８４は、ホストバス３９を介して入力されたメモリカード３のＪＰＥＧ画像を選択部８３で入れ替える画像の大きさに調整して出力する。選択部８３で入れ替えられた画像は、デコード部８１を介して、画像データとしてＮＴＳＣ／ＰＡＬエンコーダ３０に出力される。
【００６６】
次に、図１１のフローチャートを参照して、図１０のＡＶデコーダ２８が行う画像合成処理について説明する。
【００６７】
ステップＳ５１において、比較部８２は、システムコントローラ３６より供給される入れ替え可能な領域の画像の色を輝度信号ｙ０，色差信号ｃｂ０，色差信号ｃｒ０として受け取る。この色は、ユーザにより指定されたものである。
【００６８】
ステップＳ５２において、比較部８２は、デコード部８１から供給された原画像（ＤＶＤ画像）の色差信号ｃｂ、色差信号ｃｒと、システムコントローラ３６より供給された色差信号ｃｂ０，色差信号ｃｒ０の色が等しいか否かを判定する。原画像（ＤＶＤ画像）の色差信号ｃｂ，色差信号ｃｒと、システムコントローラ３６の指定した色差信号ｃｂ０，色差信号ｃｒ０の色が等しいと判定された場合、ステップＳ５４において、比較部８２は、その画素を入れ替え可能画素と決定し、その決定結果を選択部８３に出力する。
【００６９】
ステップＳ５３で、原画像（ＤＶＤ画像）の色差信号ｃｂ，色差信号ｃｒと、システムコントローラ３６が指定した色差信号ｃｂ０，色差信号ｃｒ０の色が違うと判定された場合、ステップＳ５５において、比較部８２は、その画素を入れ替え不可能画素と決定し、その決定結果を選択部８３に出力する。
【００７０】
ステップＳ５６において、比較部８２は、全ての画素について色の比較を行ったか否かを判定する。全ての画素についてまだ比較していないと判定された場合、比較部８２は、処理をステップＳ５２に戻し、次の画素についてそれ以降の処理を行う。
【００７１】
ステップＳ５６で、全ての画素について比較したと判定された場合、ステップＳ５７において、選択部８３は、入れ替え可能画素について画像の入れ替えを行う。すなわち、入れ替え可能な原画像の画素を、位置調整部８４から供給されたメモリカード３のＪＰＥＧ画像に入れ替えて、合成画像を生成させる。
【００７２】
図１２乃至図１４は、図１１の画像合成処理の画像合成例を示す図である。
【００７３】
図１２に示される画像Ｉ_Ｌは、ＤＶＤより再生された原画像であり、領域Ｒの画素の色が、システムコントローラ３６より比較部８２に供給された色（色差信号ｃｂ０，色差信号ｃｒ０により指定された色）を有する範囲であるとする。
【００７４】
一方、図１３は、メモリカード３から読み込まれたＪＰＥＧ画像Ｉ_Ｍ１を示している。図１４は、図１２の原画像Ｉ_Ｌと図１３のＪＰＥＧ画像Ｉ_Ｍ１の合成画像Ｉ_Ｗを示しており、ＪＰＥＧ画像Ｉ_Ｍ１が領域Ｒに収まるように位置調整されてＪＰＥＧ画像Ｉ_Ｍ２となっている。
【００７５】
このように、再生画の所定の領域を他の画像と入れ替えることにより、例えば、ＤＶＤに記録された俳優の画像と、メモリカードに記録されたユーザのＪＰＥＧ画像をとなり合わせるように合成すると、ユーザは、映画に出てくる俳優と自分のツーショットポートレートが作成できる。
【００７６】
ここで、合成の元となるそれぞれの画像は、静止画像に限らずＭＰＥＧ２などの動画像であってもよいし、ＪＰＥＧ以外の圧縮方式で圧縮された画像であってもよいし、圧縮されていなくてもよい。
【００７７】
上述した一連の処理は、ハードウエアにより実行させることもできるし、ソフトウエアにより実行させることもできる。一連の処理をソフトウエアにより実行させる場合には、そのソフトウエアを構成するプログラムが、専用のハードウエアに組み込まれているコンピュータ、または、各種のプログラムをインストールすることで、各種の機能を実行することが可能な、例えば汎用のパーソナルコンピュータなどに、ネットワークや記録媒体からインストールされる。
【００７８】
この記録媒体は、図２に示されるように、装置本体とは別に、ユーザにプログラムを提供するために配布される、プログラムが記録されている磁気ディスク１０１（フロッピディスクを含む）、光ディスク１０２（ＣＤ−ＲＯＭ（Ｃｏｍｐａｃｔ Ｄｉｓｋ−Ｒｅａｄ Ｏｎｌｙ Ｍｅｍｏｒｙ），ＤＶＤ（Ｄｉｇｉｔａｌ Ｖｅｒｓａｔｉｌｅ Ｄｉｓｋ）を含む）、光磁気ディスク１０３（ＭＤ（Ｍｉｎｉ−Ｄｉｓｋ）を含む）、もしくは半導体メモリ１０４などよりなるパッケージメディアにより構成される。
【００７９】
なお、本明細書において、記録媒体に記録されるプログラムを記述するステップは、記載された順番に沿って時系列的に行われる処理はもちろん、必ずしも時系列的に処理されなくとも、並列的あるいは個別に実行される処理をも含むものである。
【００８０】
【発明の効果】
以上のごとく本発明によれば、画像と音声を編集することができる。特に、ユーザの好みに応じて画像と音声を編集し、同時に再生することができる。

Similarly, the user selects any one of the DVD selection unit 54-2, the CD selection unit 55-2, the VCD selection unit 56-2, and the MS selection unit 57-2 to record the sub screen 53 in a predetermined recording state. Make it correspond to the medium.
[0032]
Further, on the main screen 52, the user selects information to be reproduced from the selected recording medium by selecting one of the audio selection unit 58-1 and the image selection unit 59-1. Similarly, the user selects information to be reproduced from the MS by selecting one of the audio selection unit 58-2 and the image selection unit 59-2 on the sub screen 53. In the example of FIG. 4, a DVD image is selected on the main screen 52, and a sound of a memory stick is selected on the sub screen 53.
[0033]
In step S2, the system controller 36 detects that a DVD on which an image to be reproduced is recorded and a memory stick on which sound is recorded are mounted. In step S2, the system controller 36 also acquires the name of the DVD and the name of the memory stick, the file name of the image file reproduced from the DVD, and the file name of the audio file reproduced from the memory stick. When the DVD (optical disk 2) or the memory stick (memory card 3) is not mounted, the system controller 36 causes the display unit 51 to display a message prompting the mounting.
[0034]
In step S3, the system controller 36 sets 1 to an internal variable i. Then, in step S4, the system controller 36 substitutes i for a variable NO for counting the synchro number (in this case, NO = 1).
[0035]
Hereinafter, the user performs an operation of reproducing a predetermined image from the DVD and reproducing a sound to be reproduced simultaneously with the image from the memory stick. That is, a program rehearsal is performed. Therefore, in step S5, the system controller 36 receives a command to start reproduction of an image designated by the user among the images recorded on the DVD from the operation unit 34 via the input I / F 35, and reproduces the image. To start. Then, in step S6, the system controller 36 sets the current time as the DVD playback start time, temporarily stores the time in the internal memory, and sets the start time window 60 on the main screen 52 (FIG. 4). To display the time. The main screen 52 also displays the reproduced image.
[0036]
That is, the image data reproduced from the optical disk 2 by the optical pickup 22 is amplified by the RF amplifier 23, then input to the demodulation unit 24 and demodulated. The ECC unit 26 corrects the error of the demodulated data and outputs it to the AV decoder 28. The AV decoder 28 decodes the input image data. The NTSC / PAL encoder 30 converts the image data decoded by the AV decoder 28 into an NTSC image signal, outputs the same to the display unit 51, and displays it.
[0037]
In step S <b> 7, the system controller 36 receives, from the operation unit 34 via the input I / F 35, a command to start playback of a sound specified by the user among sounds recorded on the memory stick (memory card 3), Start playback of the specified sound.
[0038]
That is, the DSP 31 reads out the specified audio data from the memory card 3 and decodes the data by ATRAC (Advanced Transform Acoustic Coding) 3. The DAC 32 converts the audio data input from the DSP 31 into an analog signal, and outputs the analog signal to the amplifier 33. The amplifier 33 amplifies the input audio signal and outputs it to the speakers 5-1 and 5-2.
[0039]
Then, in step S8, the system controller 36 sets the current time as the reproduction start time of the memory stick, and temporarily stores the time in the internal memory.
[0040]
The user operates the operation unit 34 when stopping reproduction of images and sounds. Therefore, in step S9, when receiving a command to stop reproduction of the sound recorded on the memory stick from the operation unit 34 via the input I / F 35, the system controller 36 stops the reproduction of the sound. Then, in step S10, the system controller 36 sets the current time as the reproduction end time of the memory stick, and temporarily stores the time in the internal memory.
[0041]
In step S11, when the system controller 36 receives a command to stop the reproduction of the image recorded on the DVD from the operation unit 34 via the input I / F 35, the system controller 36 stops the reproduction of the image. Then, in step S12, the system controller 36 sets the current time as the reproduction end time of the DVD, temporarily stores the time in the internal memory, and displays the end time window on the main screen 52 (FIG. 4). At 61, the time is displayed. In step S12, the start time and end time of the link position, the file name of the reproduced audio file, and the synchro number are temporarily stored in a memory inside the system controller 36.
[0042]
As described above, the system controller 36 stores the following information as the reproduction information of the reproduction data of the DVD and the memory stick by the processing of steps S4 to S12.

DVD start time T _vs And DVD end time T _ve Represents the time when the reproduction of the DVD image is started (time in step S6) and stopped (time in step S12). Also, the memory stick file name F _m , Memory stick start time T _ms , And memory stick end time T _me Is the file name of the audio file played from the memory stick, and the file F _m (Time of step S8) T at which the reproduction of _ms , And the time at which the reproduction was stopped (time at step S10) T _me Represents And the link start time T _Ls And link end time T _Le Indicates the start time and the end time when the reproduction of the DVD image and the sound of the memory stick are linked (overlapping). The synchro number indicates the value of the currently set variable NO. Specific examples of these times will be described later with reference to FIGS.
[0043]
In step S13, the system controller 36 determines whether a command to end the program rehearsal mode has been detected from the operation unit 34 via the input I / F 35.
[0044]
If it is determined in step S13 that the end of the program rehearsal mode has not been detected, the system controller 36 advances the process to step S14, and increases the variable i by one. Thereafter, the processing of steps S4 to S12 is repeated. Therefore, the next reproduction of the image and the sound is stored as the synchro number NO = 2.
[0045]
If it is determined in step S13 that the end of the program rehearsal mode has been detected, the system controller 36 advances the processing to step S15.
[0046]
In step S15, the system controller 36 converts the playlist composed of the start time and end time of the DVD and the memory stick temporarily stored in the internal memory into a predetermined format shown in FIG. Then, the data is stored in the memory 37.
[0047]
In the first line of the format shown in FIG. 5, the disc name and the memory stick name of the DVD are recorded. On the second line, the file name of the DVD disk and the file name of the memory stick are recorded.
[0048]
Hereinafter, information for each sync number is recorded. The information of each synchro number includes a start time of reproduction of the DVD image (main stream start time) and a period of time during which the image of the DVD is reproduced, which is synchronized with the sound of the memory stick reproduced on the sub screen 53. , Start time and end time (main stream sync start time and end time), the start time and end time of the sound of the memory stick performed on the sub screen 53 (sub stream sync start time and end time), and the main screen The time at which the reproduction of the DVD image performed at 52 ends (main stream end time).
[0049]
The main stream sync start time and the end time and the sub stream sync start time and the end time are the link position time T described above. _Ls , T _Le Corresponding to When the processing of steps S4 to S12 is repeated for each synchro number, the structure of this synchro number is sequentially added as NO = 1, 2, 3,..., N. In the last line, the order between the sync numbers is recorded. Thus, even when the order of reproduction is made different from the order of the synchro numbers, the change can be easily made only by changing the order of reproduction. A specific example of this format will be described later with reference to FIGS.
[0050]
In step S16, the system controller 36 causes the display unit 51 to display a message requesting the user to mount a storage memory stick for storing the playlist generated in step S15. The user changes the memory stick when the memory stick for storing the playlist is different from the memory stick on which the audio file is stored. When recording a playlist on the same memory stick, the user does not change the memory stick.
[0051]
When the attachment of the memory stick for storing the playlist is detected, in step S17, the system controller 36 records the playlist on the memory stick in the format shown in FIG. The storage location at this time is, for example, a predetermined location (CONT directory under the ROOT directory) as shown in FIG. Of course, the user may specify an arbitrary place.
[0052]
In the example of the above-described flowchart, the system controller 36 records and saves the playlist on the memory stick on which the sound to be reproduced is recorded, or another new memory stick, but the memory 37 of the DVD player 1 Alternatively, it may be recorded on a DVD (optical disc 2).
[0053]
FIG. 7 is a diagram showing a specific example of the program rehearsal mode processing of FIG. In the example shown in FIG. ₁ Or t ₂ Is reproduced as the synchro number NO = 1, and at the same time, the time t ₁₂ Or t _Thirteen Is playing. Next, the synchro number is set to NO = 2, and the time t of the DVD is set. ₅ Or t ₈ Are reproduced, and the time t ₆ Or t ₇ At the time t ₁₈ Or t ₁₉ Is playing. Further, assuming that the synchro number NO = 3, the time t ₄ Or t ₅ Is played back, and at the same time, the time t ₁₆ Or t ₁₇ Is playing. Finally, assuming that the synchro number is NO = 4, the time t of the DVD ₂ Or t ₄ Is reproduced, and the time t during that time is ₃ To t ₄ At the time t ₁₄ Or t _Fifteen Are playing simultaneously.
[0054]
When such reproduction is performed in the program rehearsal mode, a playlist as shown in FIG. 8 is created and recorded. That is, when the synchro number NO = 1, the main stream start time is t ₁ , The main stream sync start time and the end time are t ₁ And t ₂ , The substream sync start time and end time are t ₁₂ And t _Thirteen , The main stream end time is t ₂ It is said. When synchro number NO = 2, the main stream start time is t ₅ , The main stream sync start time and the end time are t ₆ And t ₇ , The substream sync start time and end time are t ₁₈ And t ₁₉ , The main stream end time is t ₈ It is said.
[0055]
When synchro number NO = 3, the main stream start time is t ₄ , The main stream sync start time and the end time are t ₄ And t ₅ , The substream sync start time and end time are t ₁₆ And t ₁₇ , The main stream end time is t ₅ It is said. When the synchro number is NO = 4, the main stream start time is t ₂ , The main stream sync start time and the end time are t ₃ And t ₄ , The substream sync start time and end time are t ₁₄ And t _Fifteen , The main stream end time is t ₄ It is said. The order between the synchro numbers is such that NO = 1, 2, 3, 4 and NO = 2, 3 are repeated again.
[0056]
Next, with reference to the flowchart of FIG. 9, a description will be given of a program playback synchro mode process for reading and playing a playlist recorded on a memory stick.
[0057]
First, in step S31, the system controller 36 detects that a memory stick has been mounted. Then, in step S32, the system controller 36 controls the DSP 31 to read a playlist recorded in a predetermined directory (CONT directory in the example of FIG. 6) of the memory stick.
[0058]
Since the playlist is recorded in a predetermined format as shown in FIG. 5, in step S33, the system controller 36 stores the disc name and the memory stick name recorded in the playlist in the DVD player 1. The information is displayed on the display unit 51 of the connected television receiver 4.
[0059]
When the user confirms the display, inserts the disk with the displayed name and the memory stick, and instructs to start reproduction, the system controller 36 detects the reproduction instruction through the input I / F 35 in step S34. I do.
[0060]
In step S35, the system controller 36 reproduces the image of the DVD and the sound of the memory stick in synchronization with the read playlist. When the reproduction is completed to the end of the playlist, the processing in the program reproduction sync mode ends.
[0061]
In the above-described example, the embodiment in which the image recorded on the DVD and the audio recorded on the memory stick (memory card 3) are simultaneously reproduced has been described. Images recorded on the memory card 3 by JPEG (Joint Photographic Expert Group) or the like can be simultaneously reproduced, or music recorded on a CD and an image recorded on the memory card 3 can be reproduced simultaneously. is there.
[0062]
In this way, for example, a favorite song recorded on the memory card 3 is reproduced in accordance with a favorite scene of a movie in which a favorite talent appears on the DVD (optical disc 2). Then, the user can produce a favorite album. Further, when music of a CD is reproduced in synchronization with a JPEG still image recorded on the memory card 3, the user can make the music of the CD the favorite background music for the JPEG still image. In addition, if the DVD movie is reproduced in synchronization with the sound recorded on the memory stick, the user can dub the actor's voice into his own voice or use different lines. Furthermore, if her singing voice recorded on the memory card is reproduced in synchronization with the karaoke disk, the user can always duet with her.
[0063]
In the above, the embodiment in which the image and the sound are reproduced at the same time has been described. However, the case where the image and the image are reproduced (combined) may be considered. FIG. 10 shows a configuration example of the AV decoder 28 in such a case.
[0064]
In the case of a normal decoding process, the decoding unit 81 of the AV decoder 28 converts the image data input from the ECC unit 26 (FIG. 2) into, for example, MPEG (Moving) while storing necessary data in the DRAM 29 (FIG. 2). It decodes in the Picture Experts Group (Picture Experts Group) method, and outputs, for example, image data obtained as a result of the decoding to the NTSC / PAL encoder 30 (FIG. 2).
[0065]
On the other hand, when the images are combined, the system controller 36 (FIG. 2) supplies the colors of the image in the replaceable area to the comparing unit 82 as the luminance signal y0, the color difference signal cb0, and the color difference signal cr0. The comparing unit 82 compares the luminance signal y0, the color difference signal cb0, and the color difference signal cr0 supplied from the system controller 36 with the luminance signal y, the color difference signal cb, and the color difference signal cr of the DVD image input from the decoding unit 81. Then, it is determined whether the colors are the same. This determination may be made by comparing the corresponding color difference signals, or by converting the Y, Cb, Cr signals into RGB signals, and then comparing the RGB signals. The determination result is output to the selection unit 83. The selector 83 replaces the JPEG image supplied from the position adjuster 84 with a replaceable pixel based on the determination result supplied from the comparator 82. The position adjustment unit 84 adjusts the JPEG image of the memory card 3 input via the host bus 39 to the size of the image to be replaced by the selection unit 83, and outputs the image. The image replaced by the selection unit 83 is output to the NTSC / PAL encoder 30 as image data via the decoding unit 81.
[0066]
Next, the image combining process performed by the AV decoder 28 in FIG. 10 will be described with reference to the flowchart in FIG.
[0067]
In step S51, the comparison unit 82 receives the colors of the image in the replaceable area supplied from the system controller 36 as the luminance signal y0, the color difference signal cb0, and the color difference signal cr0. This color is specified by the user.
[0068]
In step S52, the comparison unit 82 determines that the colors of the color difference signals cb and cr of the original image (DVD image) supplied from the decoding unit 81 are the same as those of the color difference signals cb0 and cr0 supplied from the system controller 36. It is determined whether or not. If it is determined that the colors of the color difference signals cb and cr of the original image (DVD image) and the color difference signals cb0 and cr0 specified by the system controller 36 are equal, in step S54, the comparison unit 82 determines whether Is determined as a replaceable pixel, and the determination result is output to the selection unit 83.
[0069]
If it is determined in step S53 that the colors of the color difference signals cb and cr of the original image (DVD image) are different from the colors of the color difference signals cb0 and cr0 specified by the system controller 36, in step S55, the comparison unit 82 is determined. Determines that the pixel is not a replaceable pixel, and outputs the determination result to the selection unit 83.
[0070]
In step S56, the comparing unit 82 determines whether the color comparison has been performed for all the pixels. When it is determined that the comparison has not been performed for all the pixels, the comparing unit 82 returns the processing to step S52, and performs the subsequent processing on the next pixel.
[0071]
If it is determined in step S56 that all pixels have been compared, in step S57, the selection unit 83 performs image replacement for the replaceable pixels. That is, the pixels of the replaceable original image are replaced with the JPEG image of the memory card 3 supplied from the position adjustment unit 84, and a combined image is generated.
[0072]
12 to 14 are diagrams illustrating an example of image synthesis of the image synthesis processing in FIG.
[0073]
Image I shown in FIG. _L Is an original image reproduced from the DVD, in a range where the colors of the pixels in the region R have the colors (colors specified by the color difference signals cb0 and cr0) supplied to the comparison unit 82 from the system controller 36. Suppose there is.
[0074]
FIG. 13 shows a JPEG image I read from the memory card 3. _M1 Is shown. FIG. 14 shows the original image I of FIG. _L And JPEG image I in FIG. _M1 Composite image I of _W And the JPEG image I _M1 Is adjusted to fit in the region R, and the JPEG image I _M2 It has become.
[0075]
As described above, by replacing a predetermined area of the reproduced image with another image, for example, when the image of the actor recorded on the DVD is combined with the JPEG image of the user recorded on the memory card so as to be aligned, the user You can create your own two-shot portrait with the actors in the movie.
[0076]
Here, each image as a source of the composition is not limited to a still image, but may be a moving image such as MPEG2, may be an image compressed by a compression method other than JPEG, or may be a compressed image. It is not necessary.
[0077]
The above-described series of processes can be executed by hardware or can be executed by software. When a series of processing is executed by software, a program constituting the software executes various functions by installing a computer built in dedicated hardware or installing various programs. For example, it is installed from a network or a recording medium into a general-purpose personal computer or the like.
[0078]
