Abstract
Description
また、特許文献2には、一つのモニタ上において視認方向による2つの映像表示それぞれに対応した2つの放送受信部が搭載されており、視認方向ごとに選局可能にした技術が開示されている。
また、特許文献3には、複数の子機モニタが放送受信部の使用状態を表示し、この使用状態の表示を確認しながらユーザが選局できる構成が開示されている。
また、上記特許文献2は、2人の視聴者がそれぞれ同時に2つの映像表示を視聴しながら選局操作できるようには構成されていないため、一方の番組を見ている間にもう一方の番組の決定的な場面を見逃すことがあるという課題があった。
また、上記特許文献3は、子機モニタ毎に選局可能に構成されているが、子機モニタに複数の画面表示を行うようには構成されていない。
また、各モニタ毎に主画面の放送番組映像と子画面の放送番組映像とを切り替えることができるので、ユーザが子画面を見て放送番組の内容を確認でき、選局を容易に行うことができる。
実施の形態1.
図1は、デジタル放送受信機1の構成を示すブロック図であり、図2は、デジタル放送受信機1の映像選択合成部50の内部構成を示すブロック図である。また、図3-1、図3-2は、二つのモニタで同じ番組を表示する場合の動作を説明する概略図であり、図4、図5は、デジタル放送受信機1の動作を示すフローチャートである。
なお、図3-1、図3-2においては、説明を容易にするために、一部構成を省略して示している。
この放送受信部10,20は、アンテナ11,21がUHF(Ultra High Frequency)帯の13~62チャンネルで放送される地上デジタルテレビジョン放送波(以下、放送波)のうち、チューナ12,22で選局された所望のチャンネルの放送波を受信し、OFDM復調部13,23により、放送波をOFDM復調してデジタル復号部30へ送る。
デマルチプレクサ31は、放送番組データとしてパケット化されて送られてきたトランスポートストリーム(Transport Stream、以下、TSと称す)を番組音声情報(オーディオストリーム)と番組映像情報(ビデオストリーム)と放送情報(カルーセル、SI(Service Information)、EPG(Electronic Program Guide)など)とに分離する。
映像分配部51は、デジタル復号部30からの放送番組映像を分配し、2つの映像縮小部52,53は、制御部83からの指示により子画面映像(縮小映像)を作成する。
2つの映像合成部54,55は、それぞれ映像分配部51により分配した少なくとも1つの放送番組映像及び映像縮小部52,53で縮小処理された番組映像を、主画面、子画面として合成する。
また、表示制御部61,71は、グラフィクス作成部33で作成されたグラフィクスと映像選択合成部50からの放送番組映像とを合成してモニタ92,97へ出力する。
モニタ92,97は、出力制御部60,70からの放送番組映像を、映像出力として出力し、スピーカ93,98は、出力制御部60,70からの放送番組音声を、音声出力として出力する。
地上デジタル放送波は、放送受信部10,20を構成する各部により受信される。チューナ12,22では放送波の所望のチャンネルを選局し、アンテナ11,21により、UHF帯の13~62チャンネルで放送される地上デジタルテレビジョン放送波を受信する。受信した放送波は、OFDM復調部13,23によりOFDM復調され放送番組データとしてのTSを出力する。TSはMPEG-2規格とARIB(Association of Radio Industries and Businesses:社団法人 電波産業会)標準規格に準拠して映像・音声や放送情報である番組情報やデータ放送、文字スーパー等を多重化したデータ列(ストリーム)である。
まず、デマルチプレクサ31によりTS1及びTS2内に多重化されている情報が解析され、番組音声情報、番組映像情報、放送情報に分離される。
なお、メニュー画面のグラフィクスは制御部83で作成することを想定しているが、グラフィクス作成部33で行ってもよい。
また、第1、第2の放送受信部で受信した放送番組映像、かつ、前席モニタ92、後席モニタ97でメイン表示される映像を番組映像ts1,ts2とする。放送番組映像ts1,ts2を縮小処理した映像を子画面映像ts1a,ts2aとする。前席モニタ92に表示される映像を前席モニタ映像92a、後席モニタ97に表示される映像を後席モニタ映像97aと定義する。
各モニタ92,97のユーザから、リモコン91a,96aを介して複数のモニタ92,97毎に設けられている操作入力部91,96にメイン表示およびメイン選局の指示が入力される。図3-1(a)に示すように、複数のモニタ92,97側で同一の放送番組の選局受信指示がされ、放送受信部10,20が同一の放送番組1を受信する場合、制御部83は、同一番組の選局受信指示を検出する。制御部83は、同一番組の選局受信指示を検出すると、図3-1(b)に示すように、放送受信部20による放送番組の受信を中止し、放送受信部10で受信した放送番組映像を分配して、同一番組を要求しているモニタ92,97に分配した放送番組映像を表示するように制御する。このとき、放送受信部20は、受信を行っていない空きの状態になっている。
また、ここで、モニタ92側の操作入力部91で子画面表示の指示がされると、図3-2(b)に示すように、制御部83は、自動的に放送受信部20で受信している放送番組2の番組映像をモニタ92の子画面として表示するように制御する。
図4に示すように、例えば、後席側出力部95において、メイン表示が指示されると、まず前席側出力部90で番組映像を表示しているかどうか、すなわち、第1の放送受信部10で放送番組を受信しているかを確認する(ステップST1)。
図5は、デジタル放送受信機1の子画面表示の動作を示すフローチャート、図6(a)は、第1の放送受信部10が受信している番組映像ts1の映像例、図6(b)は、第2の放送受信部20が受信している番組映像ts2の映像例を示す図である。
また、図7(a)、図8(a)は、前席モニタ92の子画面表示中の映像例、図7(b)、図8(b)は、後席モニタ97の子画面表示中の映像例である。
前席側出力部90の場合も同様の動作で、主画面に表示した放送番組と、子画面に表示した放送番組とを切り替えることができる。
また、ユーザからの操作に基づいて、モニタに主画面として表示した放送番組を子画面とし、子画面として表示した放送番組を主画面として表示するように切り替えることができるので、ユーザが子画面に表示された放送番組を確認しながら、選局を容易に行うことができる。
実施の形態1のデジタル放送受信機1は、2つの放送受信部で複数のモニタ毎に主画面及び子画面を表示する構成について説明したが、実施の形態2のデジタル放送受信機1は、3つの放送受信部を設け、2つの放送受信部でモニタ毎に主画面及び子画面を表示させながら、1つの放送受信部で他の放送番組の番組静止画像を蓄積して、蓄積した番組静止画像をモニタ毎に新たな子画面で順次表示させる構成について説明する。
なお、実施の形態1と同様の構成及び動作については、各部に同一の符号を付し、その説明を省略する。
図11に示すように、まず、ユーザによりリモコン91a,96aを介して操作入力部91,96から子画面表示指示されるまで待機し(ステップST21)、子画面表示指示されると(YES)、次に、使用していない放送受信部の有無を判定し(ステップST22)、放送受信部が使用中(NO)の場合、この操作が不可である旨の警告をモニタに表示して(ステップST23)ステップST21に戻る。
また、受信可能な放送番組を静止画像としてモニタ毎に子画面表示することで、各視聴者が受信可能な放送番組の内容を確認してから選局を行うことができ、各ユーザによるチャンネル選択が容易になる。
実施の形態2においては、放送番組を受信していない放送受信部100を用いて、受信可能な放送番組映像ts3の番組静止画像ts3mを蓄積し、蓄積した番組静止画像ts3mを順次読み出して子画面に表示する構成について説明したが、実施の形態3は、使用していない放送受信部で定期的に番組静止画像を蓄積する例について説明する。

作成された選択枠グラフィクスg1は、表示制御部61,71によりモニタ92,97画面上に表示され、ユーザによる操作で図12(b)に示した子画面ts3a´を選択している。
放送受信部100は選択された子画面ts3a´の放送番組をチューナ102により選局し、モニタ92,97の子画面の番組静止画像を放送番組映像ts3に切り替え、図13に示すように第1の放送受信部10と第3の放送受信部100とで受信した2つの放送番組映像を子画面で表示する。
実施の形態4においては、静止画像取得後の使用していない放送受信部100が、選択された静止画像の放送番組を選局するようにした例について説明したが、実施の形態5では、前後席それぞれのモニタ92,97で2つの放送番組映像(動画)の子画面を表示する例について説明する。
なお、デジタル放送受信機1の構成については、図9、図10と同一であるため、同一の符号を付し、その詳細な説明は省略する。

なお、デジタル放送受信機1の構成については、図9、図10と同一であるため、その詳細な説明は省略する。
図18に示すように、モニタ97の画面下部には、「2番組までの子画面選局が可能です。」と表示している。これは、例えば、3つの放送受信部10,20,100があり、そのうちの1つの放送受信部20だけが放送番組を受信し、2つの放送受信部10,100は放送を受信していない状態を示している。
また、各モニタ毎に主画面の放送番組映像と子画面の放送番組映像とを切り替えることができるので、ユーザが子画面を見て放送番組の内容を確認でき、選局を容易に行うことができる。
