Description

本発明は、自動車の前部座席や後部座席などの複数の箇所で、それぞれ携帯型映像音声再生装置から映像音声データを入力し、入力された映像音声データを各々独立に選択して再生する車載用映像音声再生システム及び車載用映像音声再生方法に関する。   The present invention provides an in-vehicle device that inputs video / audio data from a portable video / audio reproduction device and independently selects and reproduces the input video / audio data at a plurality of locations such as a front seat and a rear seat of an automobile. The present invention relates to a video / audio reproduction system for vehicle and a video / audio reproduction method for vehicle use.

車載用ＤＶＤ（Digital Versatile Disc）プレーヤによって車内でも映画を鑑賞することが可能になってきている。また、車載用ＨＤＤ（Hard Disc Drive）にＣＤ（Compact Disc）の音楽データを圧縮して大量の音楽コンテンツを記憶することができる音楽サーバの出現により、車内での楽しみ方の幅も広がってきている。特に、後部座席の乗客のためにＬＣＤ（Liquid Crystal Display）を設けて映画などを鑑賞することは、リヤシートエンターテインメントと呼ばれ、そのような楽しみ方が普及しつつある。   It has become possible to watch movies even in the car by using an in-vehicle DVD (Digital Versatile Disc) player. In addition, with the advent of music servers that can store a large amount of music content by compressing CD (Compact Disc) music data on an in-vehicle HDD (Hard Disc Drive), the range of ways to enjoy in the car has also expanded. Yes. In particular, providing LCD (Liquid Crystal Display) for passengers in the rear seats and watching movies is called rear seat entertainment, and such a way of enjoying is spreading.

車内に映像や音声データなどのマルチメディア情報を流すための車内ＬＡＮ（Local Area Network）インタフェース規格として、ＭＯＳＴ(Media Oriented Transport)やＩＤＢ(ITS/International Data Bus)−１３９４がある。これらの車内マルチメディアＬＡＮインタフェースを用いると、リヤシートを含むすべての席で音楽や映画を鑑賞することが可能になるとともに、今までダッシュボードに設置されていた車載用映像音響機器を任意の位置に複数台設置することが可能になる。そして異なる内容の映画や音楽などのコンテンツや、プレイやストップなどの機器の制御コマンドを同時に転送することが可能になる。ＭＯＳＴやＩＤＢ−１３９４の詳細については、例えば、下記の非特許文献１に記載されている。   In-vehicle LAN (Local Area Network) interface standards for flowing multimedia information such as video and audio data in the vehicle include MOST (Media Oriented Transport) and IDB (ITS / International Data Bus) -1394. Using these in-car multimedia LAN interfaces, music and movies can be watched at all seats including the rear seats, and the in-vehicle audiovisual equipment that has been installed on the dashboard up to now can be placed in any position. Multiple units can be installed. Then, it becomes possible to simultaneously transfer contents such as movies and music with different contents, and control commands for devices such as play and stop. Details of MOST and IDB-1394 are described in Non-Patent Document 1 below, for example.

一方、個人が持ち歩きながら楽しむことが可能な携帯型映像音声再生装置は既に広く普及している。携帯型映像音声再生装置としては、ＭＰ３（MPEG-1 audio layer3）やＡＡＣ（Advanced Audio Coding）などで圧縮された音声データを再生して楽しむ携帯型オーディオ再生装置、オーディオ再生機能付き携帯電話などがある。また、ＪＰＥＧ（Joint Photographic Experts Group）などで圧縮された静止画やＭＰＥＧ（Moving Picture Experts Group）−４などで圧縮された動画を見て楽しむ携帯型ビデオ再生装置、カメラ機能付き携帯電話などもある。これらの携帯型映像音声再生装置は音楽や映像の圧縮データをフラッシュＲＯＭ（Flash Read Only Memory）やＨＤＤに大量に記憶することが可能である。   On the other hand, portable video and audio playback devices that can be enjoyed while being carried by individuals are already widely used. Examples of portable video / audio playback devices include portable audio playback devices that enjoy playing audio data compressed by MP3 (MPEG-1 audio layer 3) or AAC (Advanced Audio Coding), and mobile phones with audio playback functions. is there. In addition, there are portable video players that enjoy watching still images compressed with JPEG (Joint Photographic Experts Group) and videos compressed with MPEG (Moving Picture Experts Group) -4, mobile phones with camera functions, etc. . These portable video / audio reproduction apparatuses can store a large amount of music and compressed video data in a flash ROM (Flash Read Only Memory) or HDD.

しかしながら、大量のデータを記憶するとその中から希望のコンテンツデータを探し出すことが困難になる。そのため、例えばインターネット上のＣＤＤＢ（CD Database）のようなオーディオＣＤの曲名データなどを提供するサーバから曲名を取得し、ジャンルごとに分類して携帯型オーディオ再生装置に保存することが行われている。また、携帯型映像音声再生装置では、記憶されているコンテンツの中から、視聴するコンテンツを前もって選択してプレイリストに登録しておくと、プレイリストに登録されたコンテンツの中で、ランダム再生、繰り返し再生などをすることが可能である。   However, if a large amount of data is stored, it becomes difficult to find desired content data from the stored data. For this reason, for example, song names are obtained from a server that provides audio CD song name data such as CDDB (CD Database) on the Internet, and are classified into genres and stored in portable audio playback devices. . In addition, in the portable video / audio playback device, when the content to be viewed is selected in advance from the stored content and registered in the playlist, random playback, among the content registered in the playlist, It is possible to repeat playback and the like.

前述したように、音楽サーバの出現により、車内でＣＤの音楽データを圧縮して大量の音楽コンテンツを記憶することは可能である。しかしながら、宅内で行われているようなインターネット経由で音楽データをダウンロードしたり、ＤＶＤやＨＤＤレコーダでテレビ放送を任意の時刻に録画したりすることは、インターネットへの接続に使用料金がかかる携帯電話を使用しなければならなかったり、駐車中に電力を消費することができなかったりするため、車内では宅内と同じようにしてコンテンツを記憶させることは難しかった。   As described above, with the advent of a music server, it is possible to store a large amount of music content by compressing CD music data in a car. However, downloading music data via the Internet as done at home, or recording a TV broadcast with a DVD or HDD recorder at any time, requires a mobile phone connection fee to connect to the Internet It is difficult to store content in the car in the same way as in the house because it must be used or power cannot be consumed while parking.

そのため、宅内のコンテンツを車に移動させるために前述の携帯型映像音声再生装置を利用することが考えられる。そして実際、携帯型映像音声再生装置を車載用映像音声再生装置に接続できるものが普及し始めている。   For this reason, it is conceivable to use the above-described portable video / audio reproduction device in order to move in-home content to a car. In fact, devices that can connect a portable video / audio playback device to an in-vehicle video / audio playback device are becoming popular.

しかしながら、前述の車内マルチメディアＬＡＮインタフェースが普及し、乗員が各々携帯型映像音声再生装置を持ち寄り、それぞれの携帯型映像音声再生装置を車内マルチメディアＬＡＮインタフェースに接続し、それぞれが独立に再生コンテンツの選択を可能にした場合、複数の携帯型映像音声再生装置に含まれるコンテンツから再生するコンテンツを容易に選択する手段がなかった。   However, the in-car multimedia LAN interface described above has become widespread, and passengers bring their respective portable video / audio playback devices together, connect the respective portable video / audio playback devices to the in-car multimedia LAN interface, and When selection is possible, there is no means for easily selecting content to be played back from content included in a plurality of portable video / audio playback devices.

車載用音響装置において、ＣＤチェンジャやラジオチュ−ナなどの複数のソースを複数のユーザが使用する際、割り込み的にソースを切り換える技術は、下記の特許文献１に開示されている。

ＭＯＳＴやＩＤＢ−１３９４には制御のためのＣＰＵが接続される。図１において、ＭＯＳＴやＩＤＢ−１３９４が車内マルチメディアＬＡＮインタフェース１１５として示され、これに接続されるＣＰＵに各種の機能を持たせた構成になっている。ここでは、４台の携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄを接続するための映像音声入力手段Ａ１００ａ〜映像音声入力手段Ｄ１００ｄを備え、この映像音声入力手段Ａ１００ａ〜映像音声入力手段Ｄ１００ｄが車内マルチメディアＬＡＮインタフェース１１５に接続されている。車内マルチメディアＬＡＮインタフェース１１５には、携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄからコンテンツが入力されたとき、それぞれのプレイリストを入力するためプレイリスト入力手段Ａ１０４ａ〜プレイリスト入力手段Ｄ１０４ｄと、入力されたプレイリストを収集するプレイリスト収集手段１０１と、収集されたプレイリストに基づいて統合プレイリストを作成する統合プレイリスト作成手段１０２とが接続されている。   A CPU for control is connected to the MOST and IDB-1394. In FIG. 1, MOST and IDB-1394 are shown as the in-vehicle multimedia LAN interface 115, and the CPU connected thereto has various functions. Here, the video / audio input means A100a to the video / audio input means D100d for connecting the four portable video / audio reproduction apparatuses A110a to the portable video / audio reproduction apparatus D110d are provided. A means D100d is connected to the in-vehicle multimedia LAN interface 115. When contents are input from the portable video / audio reproduction device A110a to the portable video / audio reproduction device D110d to the in-vehicle multimedia LAN interface 115, the playlist input means A104a to the playlist input means are used to input the respective playlists. D104d, a playlist collection unit 101 that collects an input playlist, and an integrated playlist creation unit 102 that creates an integrated playlist based on the collected playlist are connected.

また、車内マルチメディアＬＡＮインタフェース１１５には、それぞれソース選択手段Ａ１０３ａ〜ソース選択手段Ｄ１０３ｄを介して、映像音声を再生する再生手段Ａ１１１ａ〜再生手段Ｄ１１１ｄが接続されている。このうち、再生手段Ａ１１１ａにはＬＣＤＡ１１２ａとスピーカ１１３とが接続され、再生手段Ｂ１１１ｂ〜再生手段Ｄ１１１ｄには、それぞれＬＣＤＢ１１２ｂ及びヘッドホンＢ１１４ｂ〜ＬＣＤＤ１１２ｄ及びヘッドホンＤ１１４ｄが接続されている。   The in-car multimedia LAN interface 115 is connected to playback means A111a to playback means D111d for playing back video and audio via source selection means A103a to source selection means D103d, respectively. Among them, the LCD A 112a and the speaker 113 are connected to the reproducing means A 111a, and the LCD B 112b and the headphones B 114b to LCD D 112d and the headphones D 114d are connected to the reproducing means B 111b to the reproducing means D 111d, respectively.

上述したプレイリスト収集手段１０１、統合プレイリスト作成手段１０２、映像音声入力手段Ａ１００ａ〜映像音声入力手段Ｄ１００ｄ、プレイリスト入力手段Ａ１０４ａ〜プレイリスト入力手段Ｄ１０４ｄ、再生手段Ａ１１１ａ〜再生手段Ｄ１１１ｄはいずれも車内マルチメディアＬＡＮインタフェース１１５に接続されるＣＰＵに持たせた機能であり、各機能名称の後に付した「Ａ」、「Ｂ」、「Ｃ」、「Ｄ」はそれぞれ車内の座席位置に対応させた識別符号である。   The playlist collection means 101, integrated playlist creation means 102, video / audio input means A100a to video / audio input means D100d, playlist input means A104a to playlist input means D104d, and playback means A111a to playback means D111d are all in the vehicle. This function is given to the CPU connected to the multimedia LAN interface 115, and “A”, “B”, “C”, and “D” after each function name correspond to the seat position in the car. It is an identification code.

ここで、再生手段Ａ１１１ａにのみスピーカ１１３が接続され、これ以外の再生手段Ｂ１１１ｂ〜再生手段Ｄ１１１ｄにヘッドホンＢ１１４ｂ〜ヘッドホンＤ１１４ｄが接続されている理由は、互いに異なるソースを同時に再生したとき、音声が混じるのを防いでユーザがコンテンツを快適に視聴するためである。また、４台の携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄにはそれぞれ図３Ａ〜図３Ｄに示すプレイリストがユーザによって前もって設定されている。そして、携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄが映像音声入力手段Ａ１００ａ〜映像音声入力手段Ｄ１００ｄに接続されたとき、プレイリスト入力手段Ａ１０４ａ〜プレイリスト入力手段Ｄ１０４ｄによって、図３Ａ〜図３Ｄに示すプレイリストが繰り返し再生されるものとする。なお、再生手段Ａ１１１ａ〜再生手段Ｄ１１１ｄ、ＬＣＤＡ１１２ａ〜ＬＣＤＤ１１２ｄ、スピーカ１１３、及びヘッドホンＢ１１４ｂ及びヘッドホンＤ１１４ｄが本発明の車載用映像音声再生システムを構成している。また、ＬＣＤＡ１１２ａ〜ＬＣＤＤ１１２ｄは本発明のプレイリスト表示手段の機能をも備えている。   Here, the reason why the speaker 113 is connected only to the reproducing means A111a and the headphones B114b to D114d are connected to the other reproducing means B111b to D111d is that when different sources are reproduced simultaneously, the sound is mixed. This is to prevent the user from watching the content comfortably. In addition, playlists shown in FIGS. 3A to 3D are set in advance by the user in each of the four portable video / audio reproduction devices A110a to D110d. When the portable video / audio reproduction device A110a to the portable video / audio reproduction device D110d are connected to the video / audio input unit A100a to the video / audio input unit D100d, the playlist input unit A104a to the playlist input unit D104d perform FIG. Suppose that the playlist shown in FIG. The reproduction means A111a to reproduction means D111d, LCDA112a to LCDD112d, speaker 113, headphone B114b, and headphone D114d constitute the in-vehicle video / audio reproduction system of the present invention. The LCDA 112a to LCDD 112d also have the function of the playlist display means of the present invention.

上記のように構成された第１の実施の形態の動作について、図２のフローチャートに従って、さらに、図３Ａ〜図３Ｄに示したプレイリストの例及び図４に示した統合プレイリストの表示画面例をも参照して以下に説明する。まず、携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄが映像音声入力手段Ａ１００ａ〜映像音声入力手段Ｄ１００ｄに接続されて再生動作を開始すると、映像音声入力手段Ａ１００ａ〜映像音声入力手段Ｄ１００ｄは映像音声データを車内マルチメディアＬＡＮインタフェース１１５に送出する。そのとき、プレイリスト入力手段Ａ１０４ａ〜プレイリスト入力手段Ｄ１０４ｄはそれぞれ対応するプレイリストを車内マルチメディアＬＡＮインタフェース１１５に送出する。   With respect to the operation of the first embodiment configured as described above, according to the flowchart of FIG. 2, the example of the playlist shown in FIGS. 3A to 3D and the display example of the integrated playlist shown in FIG. Is described below with reference to FIG. First, when the portable video / audio reproduction device A110a to the portable video / audio reproduction device D110d are connected to the video / audio input means A100a to the video / audio input means D100d and start the reproduction operation, the video / audio input means A100a to the video / audio input means D100d. Sends the audio / video data to the in-vehicle multimedia LAN interface 115. At that time, each of the playlist input means A 104 a to the playlist input means D 104 d sends the corresponding playlist to the in-car multimedia LAN interface 115.

そこで、ステップＳ２００でプレイリスト収集手段１０１はプレイリストの収集先を携帯型映像音声再生装置Ａ１１０ａに設定し（対象機器＝Ａと記載）、ステップＳ２０１で携帯型映像音声再生装置Ａ１１０ａのプレイリストを収集する。図３Ａは携帯型映像音声再生装置Ａ１１０ａのプレイリストを示している。次に、ステップＳ２０２ですべての機器、すなわち携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄのプレイリストの収集が終了したか否かを判定し、終了していなければステップＳ２０３にてプレイリストの収集先を次の機器、例えば携帯型映像音声再生装置Ｂ１１０ｂに設定し、ステップＳ２０１で携帯型映像音声再生装置Ｂ１１０ｂのプレイリストを収集し、ステップＳ２０３で携帯型映像音声再生装置Ｄ１１０ｄのプレイリストの収集が終了したと判定するまで、ステップＳ２０１〜ステップＳ２０３の処理を繰り返す。図３Ｂ〜図３Ｄはそれぞれ携帯型映像音声再生装置Ｂ１１０ｂ〜携帯型映像音声再生装置Ｄ１１０ｄのプレイリストを示している。   Therefore, in step S200, the playlist collection unit 101 sets the collection destination of the playlist to the portable video / audio playback device A 110a (target device = A), and in step S201, the playlist collection unit 101 sets the playlist of the portable video / audio playback device A 110a. collect. FIG. 3A shows a playlist of the portable video / audio reproduction device A110a. Next, in step S202, it is determined whether or not the playlist collection of all the devices, that is, the portable video / audio playback device A110a to the portable video / audio playback device D110d is completed. The playlist collection destination is set to the next device, for example, the portable video / audio reproduction device B110b, the playlist of the portable video / audio reproduction device B110b is collected in step S201, and the portable video / audio reproduction device D110d is collected in step S203. Until it is determined that the playlist collection has been completed, the processes in steps S201 to S203 are repeated. 3B to 3D show playlists of the portable video / audio reproduction device B110b to the portable video / audio reproduction device D110d, respectively.

次に、ステップＳ２０４で、統合プレイリスト作成手段１０２はプレイリスト収集手段１０１で収集されたプレイリストを、そのプレイリストが設定されていた携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄと対応することが分かるように統合プレイリストを作成する。図４は作成された統合プレイリストを示している。続いて、ステップＳ２０５で、この統合プレイリストがＬＣＤＡ１１２ａ〜ＬＣＤＤ１１２ｄ（図４では１１２と記す）に表示される。そこで、ステップＳ２０６でユーザはＬＣＤＡ１１２ａ〜ＬＣＤＤ１１２ｄに表示された統合プレイリストを見て、好みの機器Ａ〜機器Ｄ、すなわち携帯型映像音声再生装置Ａ１１０ａ〜携帯型映像音声再生装置Ｄ１１０ｄのソース（映像音声）をソース選択ボタン１１６ａ〜１１６ｄによって選択する。図４に示したソース選択ボタン１１６ａ〜１１６ｄが図１に示したソース選択手段Ａ１０３ａ〜ソース選択手段Ｄ１０３ｄに対応している。   Next, in step S204, the integrated playlist creation unit 102 selects the playlist collected by the playlist collection unit 101 from the portable video / audio playback device A110a to portable video / audio playback device D110d in which the playlist is set. Create an integrated playlist so that FIG. 4 shows the created integrated playlist. Subsequently, in step S205, this integrated playlist is displayed on the LCDA 112a to LCDD 112d (denoted as 112 in FIG. 4). Therefore, in step S206, the user looks at the integrated playlist displayed on the LCDA 112a to LCDD 112d, and selects the source (video / audio) of the desired device A to device D, that is, the portable video / audio playback device A 110a to D110d. ) Is selected by the source selection buttons 116a to 116d. The source selection buttons 116a to 116d shown in FIG. 4 correspond to the source selection means A103a to source selection means D103d shown in FIG.
