　以下、本発明の実施例について図面を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図１は、実施例１にかかる番組視聴システムの概念を示す図である。この番組視聴システムでは、携帯端末装置（以下、端末と呼称）と、デジタルテレビジョン（以下、ＤＴＶと呼称）、及び録画機能付きケーブルテレビ受信機（以下、ＣＡＴＶ／レコーダと呼称）等を接続して構成している。 FIG. 1 is a diagram illustrating a concept of a program viewing system according to the first embodiment. In this program viewing system, a portable terminal device (hereinafter referred to as a terminal), a digital television (hereinafter referred to as DTV), a cable television receiver with a recording function (hereinafter referred to as CATV / recorder) and the like are connected. Is configured.
　ＤＴＶ１３０やＣＡＴＶ／レコーダ１４０は、各々アンテナ信号１２０（以下、ＲＦ信号と呼称）もしくは光ケーブル１４１から放送信号を受信する。ＤＴＶとＣＡＴＶ／レコーダの間ではデジタルＡＶ信号１３１を送受信し、放送番組の表示や録画を行う。また端末１００は、地上デジタル放送の電波をアンテナで受信し、放送番組を表示視聴する。 The DTV 130 and CATV / recorder 140 each receive a broadcast signal from an antenna signal 120 (hereinafter referred to as an RF signal) or an optical cable 141. A digital AV signal 131 is transmitted and received between the DTV and the CATV / recorder, and a broadcast program is displayed and recorded. The terminal 100 receives radio waves of terrestrial digital broadcasting with an antenna, and displays and views the broadcast program.
　さらに端末１００では、ＤＴＶ１３０やＣＡＴＶ／レコーダ１４０が受信した放送番組を、無線ＬＡＮ等の通信手段を介して制御／映像信号１５０として受信し、表示することもできる。その場合には、ＤＴＶ１３０やＣＡＴＶ／レコーダ１４０は電源ＯＦＦの状態であっても、内蔵されたチューナーと無線ＬＡＮ等の通信手段の部分のみが電源供給されていればよい。 Further, the terminal 100 can also receive and display the broadcast program received by the DTV 130 or CATV / recorder 140 as the control / video signal 150 via communication means such as a wireless LAN. In that case, even if the DTV 130 and the CATV / recorder 140 are in the power-off state, only the built-in tuner and the communication means such as the wireless LAN need only be supplied with power.
　ここで、端末１００として画面の表示形式が異なる２つの例を示す。端末１００ａの画面には、番組映像とともに表示中の番組の放送局名と番組名を表示している。端末１００ｂの画面には、番組映像とともに現在放送中の他の放送局名と番組名を一覧表示している。本実施例の特徴として、端末１００ａと端末１００ｂでは、表示番組（チャンネル）の切り替えやＤＴＶ１３０への表示切り替えを以下のように行う。 Here, two examples of different display formats of the screen as the terminal 100 are shown. On the screen of the terminal 100a, the broadcast station name and program name of the program being displayed are displayed together with the program video. On the screen of the terminal 100b, a list of other broadcast station names and program names currently being broadcast are displayed together with the program video. As a feature of the present embodiment, the terminal 100a and the terminal 100b perform display program (channel) switching and display switching to the DTV 130 as follows.
　端末１００ａの画面にはタッチパネルが搭載されており、表示している番組映像をタッチペン１０２もしくは指でタッチした後、左右いずれかにスライド（以下、スワイプと呼称）することで、隣接するチャンネルの番組映像に切り替える。このとき、端末１００ａが地上波デジタル放送を自身のチューナーで直接受信している場合は、端末自身でチャンネルを切り替える。また、ＤＴＶ１３０もしくはＣＡＴＶ／レコーダ１４０を経由して番組映像を受信している場合は、制御／映像信号１５０を用いてＤＴＶもしくはＣＡＴＶ／レコーダへチャンネルの切り替えを要求し、受信した番組映像を画面に表示する。 A touch panel is mounted on the screen of the terminal 100a, and after touching the displayed program video with the touch pen 102 or a finger, it slides to the left or right (hereinafter referred to as swipe), so that the program of the adjacent channel is displayed. Switch to video. At this time, if the terminal 100a directly receives the terrestrial digital broadcast by its own tuner, the terminal itself switches the channel. When a program video is received via the DTV 130 or CATV / recorder 140, the control / video signal 150 is used to request the DTV or CATV / recorder to switch channels, and the received program video is displayed on the screen. indicate.
　また、端末Ａ１００ａにてある番組映像を表示している状態で、端末の横に設けたボタン１０１を押すと、ＤＴＶ１３０の電源が入り、端末１００ａで表示していた番組映像を大画面のＤＴＶにて表示する。すなわち、端末１００ａにて視聴しているチャンネルの映像を、ボタン１０１を押すだけの操作で、直ちに大画面のＤＴＶの映像表示に切り替えて視聴することができる。 Further, when a button 101 provided on the side of the terminal is pressed while a program video is being displayed on the terminal A 100a, the DTV 130 is turned on, and the program video displayed on the terminal 100a is turned into a large screen DTV. To display. That is, the video of the channel being viewed on the terminal 100a can be immediately switched to the large-screen DTV video display by simply pressing the button 101 and viewed.
　次に、端末１００ｂの場合には、一覧表示している放送局名もしくは番組名から、所望の項目をタッチペン１０２もしくは指でタッチすることで、その放送局に切り替えて、所望の番組映像の表示を行うことができる。また、ボタン１０１を押すことで、表示している番組映像を大画面のＤＴＶ１３０の表示に切り替え、視聴することができる。 Next, in the case of the terminal 100b, a desired item is touched with a touch pen 102 or a finger from a list of broadcast station names or program names to switch to the broadcast station, and display of a desired program video is displayed. It can be performed. Also, by pressing the button 101, the displayed program video can be switched to the display on the large-screen DTV 130 and viewed.
　ＤＴＶでの視聴開始後は、端末のアプリケーションの動作を終了してもよいが、リモコン機能は継続して使用できるようにしてもよい。 After the start of viewing on the DTV, the operation of the terminal application may be terminated, but the remote control function may be continuously used.
　図２は、図１の番組視聴システムにおける機器構成を示すブロック図である。ここでは、ＣＡＴＶ回線にてインターネットに接続する構成とし、ＣＡＴＶの映像信号に接続される機器とネットワーク接続される機器との相互の繋がりを示している。 FIG. 2 is a block diagram showing a device configuration in the program viewing system of FIG. Here, it is assumed that the apparatus is connected to the Internet via a CATV line, and shows the mutual connection between the apparatus connected to the CATV video signal and the apparatus connected to the network.
　インターネット２０１からの情報は、ＣＡＴＶの光ケーブル２１１により屋内に持ち込まれる。この光ケーブルからの情報は、Ｉ／Ｆ　ＢＯＸ２１０にて分離され、映像信号を含むデジタル信号２１２と、インターネット信号を含むデジタル信号２１３が出力される。デジタル信号２１２は例えば同軸ケーブルでＣＡＴＶ２２０へ、デジタル信号２１３は例えばイーサネット（登録商標）ケーブルにて屋内ルータ２４０へ出力される。なお、同軸ケーブルのデジタル信号２１２は、アンテナから受信する放送電波であるＲＦ信号２９１と同等のものである。なお、各機器へ供給するデジタル信号２１２は放送電波から入力するのが一般的ではあるが、ここではＣＡＴＶ特有の番組を視聴できるように、一般のアンテナから入力したＲＦ信号２９１とは別系統で構成している。 Information from the Internet 201 is brought indoors by a CATV optical cable 211. Information from the optical cable is separated by the I / F BOX 210, and a digital signal 212 including a video signal and a digital signal 213 including an Internet signal are output. The digital signal 212 is output to the CATV 220 via a coaxial cable, for example, and the digital signal 213 is output to the indoor router 240 via an Ethernet (registered trademark) cable, for example. The digital signal 212 of the coaxial cable is equivalent to the RF signal 291 that is a broadcast radio wave received from the antenna. The digital signal 212 to be supplied to each device is generally input from a broadcast wave, but here, in order to be able to view a program specific to CATV, it is a separate system from the RF signal 291 input from a general antenna. It is composed.
　ＣＡＴＶ２２０では、ユーザーにより選択されたチャンネルについて内蔵するチューナーにより受信し、圧縮されたデジタル映像を復号してデジタルＡＶ信号２１４をＤＴＶ２３０に送り、ＤＴＶにて番組映像を視聴する。また、ＤＴＶ２３０、レコーダ２７０及びポータブルＤＴＶ２９０は、それぞれ通常のデジタル放送を受信するチューナーを内蔵しているので、一般放送のＲＦ信号２９１を入力することで、それぞれ単独でデジタル放送の受信や表示を行うことができる。すなわちＤＴＶ２３０は、自身のチューナーで受信した放送番組と、ＣＡＴＶ２２０にて受信したＣＡＴＶ専用の番組から、所望の番組を選択し視聴することができる。 The CATV 220 receives the channel selected by the user by the built-in tuner, decodes the compressed digital video, sends the digital AV signal 214 to the DTV 230, and views the program video on the DTV. The DTV 230, the recorder 270, and the portable DTV 290 each have a built-in tuner that receives normal digital broadcasts. Therefore, by receiving a general broadcast RF signal 291, each receives and displays digital broadcasts independently. be able to. That is, the DTV 230 can select and watch a desired program from the broadcast program received by its tuner and the CATV-dedicated program received by the CATV 220.
　レコーダ２７０は、ＲＦ信号２９１として入力された放送番組を内蔵するハードディスク（ＨＤＤ）等に録画する。またこれを再生してデジタルＡＶ信号２３１をＤＴＶ２３０に送り、ＤＴＶにて再生映像を視聴することができる。ポータブルＤＴＶ２９０は、屋内を自由に持ち歩けるハンディ型ＤＴＶであり、バッテリーで駆動でき、またＤＶＤやブルーレイディスク（ＢＤ、登録商標）の再生も可能である。 The recorder 270 records the broadcast program input as the RF signal 291 on a hard disk (HDD) or the like built in. In addition, the digital AV signal 231 is transmitted to the DTV 230 so that the reproduced video can be viewed on the DTV. The portable DTV 290 is a handheld DTV that can be carried around indoors, can be driven by a battery, and can also reproduce a DVD or a Blu-ray Disc (BD, registered trademark).
　一方、Ｉ／Ｆ　ＢＯＸ２１０で分離されたデジタル信号２１３は屋内ルータ２４０に送られ、屋内ルータは屋内の各インターネット対応機器にＩＰアドレスを自動付与して、屋内ＬＡＮ２４１を構築している。本例ではインターネット対応機器として、ＰＣ２５０）やＮＡＳ（ネットワークアクセスストレージ）２６０を記載したが、上記したＤＴＶ２３０やレコーダ２７０、ポータブルＤＴＶ２９０でもインターネット接続が可能である。これらの機器は、さらに無線ＬＡＮ２８０を経由して、携帯電話、スマートフォンなどの携帯端末装置（端末）２００と接続されている。 On the other hand, the digital signal 213 separated by the I / F BOX 210 is sent to the indoor router 240, and the indoor router automatically assigns an IP address to each indoor Internet-compatible device to construct the indoor LAN 241. In this example, PC 250) and NAS (network access storage) 260 are described as Internet-compatible devices, but the above-described DTV 230, recorder 270, and portable DTV 290 can also be connected to the Internet. These devices are further connected to a mobile terminal device (terminal) 200 such as a mobile phone or a smartphone via a wireless LAN 280.
　端末２００は、自身のアンテナでワンセグ放送の番組を受信するだけでなく、無線ＬＡＮ２５０を経由してＤＴＶ２３０、レコーダ２７０、またはＣＡＴＶ２２０からそれらのチューナーで受信した放送番組を入手して、所望の番組を選択し視聴することができる。さらに端末２００は、ボタン１０１の押下げ操作により、大画面のＤＴＶ２３０での映像表示に切り替えることができる。その場合は、端末２００は視聴中のチャンネル番号をＤＴＶ２３０に送り、ＤＴＶは自身のチューナーにより受け取ったチャンネル番号の放送番組を受信して表示する。 The terminal 200 not only receives a one-segment broadcast program with its own antenna, but also obtains a broadcast program received by the tuner from the DTV 230, the recorder 270, or the CATV 220 via the wireless LAN 250, and selects a desired program. You can select and watch. Furthermore, the terminal 200 can be switched to video display on the large-screen DTV 230 by pressing the button 101. In that case, the terminal 200 sends the channel number being viewed to the DTV 230, and the DTV receives and displays the broadcast program of the channel number received by its tuner.
　図３は、携帯端末装置（端末）のハードウェア構成を示すブロック図である。図１、図２における端末１００，２００は、ＣＰＵ３００と以下に述べる各要素がバス３１１を介して接続された構成となっている。 FIG. 3 is a block diagram showing a hardware configuration of the mobile terminal device (terminal). The terminals 100 and 200 in FIGS. 1 and 2 have a configuration in which a CPU 300 and each element described below are connected via a bus 311.

　図５は、携帯端末装置の基本動作を示すフローチャートである。ステップ順に説明する
　Ｓ５００では、視聴するチャンネルの初期設定を行う。その場合、（ａ）過去に最後に見たチャンネル、あるいは（ｂ）予め指定したチャンネルなどに設定する。Ｓ５０１では、端末は初期設定されたチャンネルの映像を受信し、Ｓ５０２では、受信した映像を表示部（ＬＣＤ）３１２に表示する。 FIG. 5 is a flowchart showing the basic operation of the mobile terminal device. In step S500, which will be described in the order of steps, initial setting of channels to be viewed is performed. In that case, (a) the channel that was last seen in the past, or (b) the channel that has been designated in advance is set. In step S <b> 501, the terminal receives an image of an initially set channel. In step S <b> 502, the terminal displays the received image on the display unit (LCD) 312.
　Ｓ５０３で、端末がＯＦＦ操作された場合、もしくは端末の本動作アプリケーションが終了された場合、端末のリモコン機能はＯＦＦとなり、その結果Ｓ５０９でＤＴＶ他の全ＡＶ機器を一斉にＯＦＦとすることができる。これより、各機器の電源ＯＦＦをそれぞれ行う手間が省ける。 When the terminal is turned off in S503 or when the terminal operation application is terminated, the remote control function of the terminal is turned off, and as a result, all the DTV and other AV devices can be turned off all at once in S509. . This saves the trouble of turning off the power of each device.
　Ｓ５０４で、ボタン１０１の押し下げによりＤＴＶ表示が選択されると、Ｓ５０５へ進み、端末で現在受信中のチャンネル番号をＤＴＶ２３０に送信し、ＤＴＶにて同一チャンネルの番組を受信して表示させる。このように端末は、ＤＴＶに対し映像データを送信することなく、チャンネル番号を送るだけでよい。 When the DTV display is selected by pressing the button 101 in S504, the process proceeds to S505, where the channel number currently received by the terminal is transmitted to the DTV 230, and the program of the same channel is received and displayed by the DTV. In this way, the terminal only needs to send the channel number without sending video data to the DTV.
　その後端末は、Ｓ５０６に進み、端末で受信中の番組の映像と音声をＯＦＦする。なお、（ａ）音声を消して映像＋番組表を表示する、あるいは（ｂ）番組表のみを表示する、としてもよい。番組表を表示しておけば、ＤＴＶのリモコンとして利用することができる。すなわち、端末上で所望の番組を選択することで、赤外線もしくは無線ＬＡＮ経由でＤＴＶ、レコーダ、ＣＡＴＶのチャンネルを切り替えることができる。また、（ａ）の場合には、ＤＴＶでの表示番組と関係なく、端末で他のチャンネルの番組映像を確認することができる。 Thereafter, the terminal proceeds to S506 and turns off the video and audio of the program being received by the terminal. Note that (a) the sound may be turned off and the video + program guide may be displayed, or (b) only the program guide may be displayed. If the program guide is displayed, it can be used as a remote control for DTV. That is, by selecting a desired program on the terminal, channels of DTV, recorder, and CATV can be switched via infrared or wireless LAN. In the case of (a), the program video of another channel can be confirmed on the terminal regardless of the display program on the DTV.
　Ｓ５０７では、端末にてチャンネル変更の操作を受けると、Ｓ５０８に進み新たなチャンネルに切り替える。そしてＳ５０１に戻り、新たなチャンネルの映像を受信する。以下、これを繰り返す。 In S507, when a channel change operation is received at the terminal, the process proceeds to S508 to switch to a new channel. Then, the process returns to S501 to receive a new channel video. This is repeated below.
　図６は、携帯端末装置にてチャンネル変更操作を行うイメージ図である。（ａ）～（ｆ）は、ユーザーが映像を見ながらチャンネル変更を行う場合である。 FIG. 6 is an image diagram for performing a channel change operation on the mobile terminal device. (A) to (f) are cases where the user changes the channel while viewing the video.
　（ａ）に示すように、端末１００の画面には、現在選択中のチャンネルの映像６０１に加え、その両側に隣接するチャンネルの映像６０２，６０３を一緒に表示する。（ｂ）のように、画面上をタッチペン１０２もしくは指でスワイプして映像を左右にスライドすることで、（ｃ）のように隣接チャンネルの映像（例えば６０３）に切り替えることができる。ここで隣接チャンネルとは、放送局チャンネル番号順に隣接するものに限定しない。ユーザーが独自に番組表の順序を並べ替えることで、関連するチャンネル同士（例えばスポーツ放送チャンネルが複数ある場合）を隣接して並べ、選択することが可能になる。 As shown in (a), on the screen of the terminal 100, in addition to the image 601 of the currently selected channel, the images 602 and 603 of the adjacent channels on both sides thereof are displayed together.

　図８は、携帯端末装置で表示している番組をＤＴＶでの表示へ切り替える方法を示す図である。 FIG. 8 is a diagram illustrating a method of switching a program displayed on the mobile terminal device to display on the DTV.
　（ａ）は、端末１００に設けたハードウェアボタン８０１の押下げ動作により、端末で選択表示している番組を大画面のＤＴＶでの表示に切り替えるものである。このハードウェアボタン８０１は、図１のボタン１０１や図３のハードスイッチ３０５に相当する。

(C) When the OFF icon 803 is selected from the icons 802 in (b) with the touch pen 102 or the finger, the video / audio output of the terminal can be turned OFF (OFF operation in S506 in FIG. 5).
　図９は、携帯端末装置と接続機器間のデータの流れを示す図である。図２の構成図を用いてデータの流れを示している。 FIG. 9 is a diagram showing a data flow between the mobile terminal device and the connected device. The flow of data is shown using the block diagram of FIG.
　端末２００ではレコーダ２７０のチューナーで受信した放送番組を視聴している場合を示す。レコーダ２７０で受信した映像信号９０１は、無線ＬＡＮ２８０を経由して端末２００に送信され、表示される。端末２００でＤＴＶ２３０への表示を指示したとき、レコーダ２７０からＤＴＶ２３０へデジタル映像信号９０２を送信し、ＤＴＶ２３０での映像表示に切り替わる。このように、端末２００からＤＴＶ２３０へデジタル映像信号９０２を送信する必要はない。 The terminal 200 shows a case where a broadcast program received by the tuner of the recorder 270 is being viewed. The video signal 901 received by the recorder 270 is transmitted to the terminal 200 via the wireless LAN 280 and displayed. When the display on the DTV 230 is instructed by the terminal 200, the digital video signal 902 is transmitted from the recorder 270 to the DTV 230, and the display is switched to the video display on the DTV 230. As described above, it is not necessary to transmit the digital video signal 902 from the terminal 200 to the DTV 230.
　以上述べたように実施例１の構成によれば、携帯端末装置にて自身で受信できない番組を含めて視聴可能となる。また、携帯端末装置で視聴している番組映像をテレビジョンでの表示に簡単に切り替えることができる。よって、使い勝手の良い番組視聴システムを提供できる。 As described above, according to the configuration of the first embodiment, it is possible to view a program including a program that cannot be received by the mobile terminal device. Further, it is possible to easily switch the program video being viewed on the mobile terminal device to the display on the television. Therefore, a user-friendly program viewing system can be provided.
　実施例２では、番組視聴システムにおけるリソースの有効利用と使い勝手向上について説明する。 Example 2 describes effective use of resources and improvement in usability in a program viewing system.
　図１０は、番組視聴システムにおける受信機能リソースの割り当てを示す図である。番組視聴システムでは、端末，ＤＴＶ，レコーダ，ＣＡＴＶ等はそれぞれ受信機能（チューナー）を備えており、これらの複数の受信機能リソースを組み合わせて、効率的な画面表示を行う。ここでは、図６に示した端末の画面表示を想定し、選択中の番組映像（メイン映像）と、その両側に隣接チャンネルの番組映像（サブ映像）を表示するものとする。 FIG. 10 is a diagram showing allocation of reception function resources in the program viewing system. In the program viewing system, terminals, DTVs, recorders, CATVs, etc. each have a reception function (tuner), and these multiple reception function resources are combined to perform efficient screen display. Here, assuming that the terminal screen shown in FIG. 6 is displayed, the currently selected program video (main video) and the program video (sub video) of the adjacent channel are displayed on both sides thereof.
　（ａ）の構成では、３個のチューナー１００１～１００３を用いてメイン映像と２つのサブ映像を受信し、３個のデコーダ１００４～１００６でそれぞれの信号のデコードを行う。合成部１００７ではこれらの信号を合成し、合成した映像を端末の表示部（ＬＣＤ）３１２に表示し、またその音声をスピーカー３０８から出力する。 In the configuration of (a), the main video and the two sub-videos are received using the three tuners 1001 to 1003, and the respective signals are decoded by the three decoders 1004 to 1006. The synthesizer 1007 synthesizes these signals, displays the synthesized video on the display unit (LCD) 312 of the terminal, and outputs the sound from the speaker 308.
　（ｂ）の構成では、３個のチューナー１００１～１００３を使うが、デコーダは２個（１００４，１００５）に削減している。中央のメイン映像には第１のデコーダ１００４を割り当て、通常の表示を行う。一方、両側の２つのサブ映像については、チューナーはそれぞれ占有するがデコーダは第２のデコーダ１００５を共有する。両サイド画面用処理回路１００８では、２つのサブ映像のフレーム信号を交互に出力する。合成部１００７はこれらの信号を合成する。これによりサブ映像の表示フレームレートは半分になるが、隣接チャンネルの画面の一部分を表示するだけなので、フレームレート低下の影響は少ない。この構成は、端末がダイバーシティ受信方式で複数のチューナーを持っている場合に特に有効となる。 In the configuration of (b), three tuners 1001 to 1003 are used, but the number of decoders is reduced to two (1004, 1005). A first decoder 1004 is assigned to the central main video, and normal display is performed. On the other hand, the two sub-pictures on both sides are occupied by the tuner, but the decoder shares the second decoder 1005. Both side screen processing circuit 1008 alternately outputs frame signals of two sub-pictures. The synthesizer 1007 synthesizes these signals. As a result, the display frame rate of the sub video is halved, but only a part of the screen of the adjacent channel is displayed, so the influence of the frame rate reduction is small. This configuration is particularly effective when the terminal has a plurality of tuners in the diversity reception system.
　図１１は、携帯端末装置とＤＴＶの通信を同室内に限定するための構成図である。ＤＴＶと同一室内にある端末のみが、ＤＴＶの制御を行うことができ、室外（隣室）の端末からＤＴＶの選局を勝手に切り替えることを防止するものである。 FIG. 11 is a configuration diagram for limiting communication between the portable terminal device and the DTV in the same room. Only the terminal in the same room as the DTV can control the DTV, and prevents the channel selection of the DTV from the terminal in the outdoor (adjacent room).
　ＤＴＶ１３０は、赤外線信号１１０１を常時送信し続ける。同室にいる端末１００はこれを受信し、受信した旨の信号を無線ＬＡＮ１１０２経由でＤＴＶ１３０に返信することで、接続承認される。これにより端末１００はＤＴＶ１３０を制御する権限を得る。なお、赤外線信号１１０１は、ＤＴＶの代わりにセットトップボックス（ＣＡＴＶ、レコーダ）から送信しても構わない。 The DTV 130 keeps transmitting the infrared signal 1101 at all times. The terminal 100 in the same room receives this, and the connection is approved by returning a signal indicating the reception to the DTV 130 via the wireless LAN 1102. As a result, the terminal 100 has the authority to control the DTV 130. Note that the infrared signal 1101 may be transmitted from a set top box (CATV, recorder) instead of the DTV.
　ここに赤外線信号１１０１は、（ａ）特定の周波数の信号、あるいは（ｂ）メーカーコード、機器コード等を表したビット列（現行ＡＶリモコンと同様）の信号とする。赤外線信号以外として音声信号でもよく、隣室に届かない、同室の端末のみが受信できる信号であればよい。 Here, the infrared signal 1101 is (a) a signal of a specific frequency, or (b) a signal of a bit string (similar to the current AV remote controller) representing a manufacturer code, a device code, and the like. An audio signal other than the infrared signal may be used as long as the signal does not reach the adjacent room and can be received only by the terminal in the same room.
　図１２は、番組視聴システムにおける各種動作形態を示す図である。
  （ａ）のように、ここではワーストケースとして、ＤＴＶ、レコーダ、ＣＡＴＶの３個のチューナー１２０１～１２０３のみを用いる場合を想定する。これらに接続する３個のモジュール１２０４～１２０６は、録画動作１２０７、ＬＡＮ経由による映像信号の外部宛送信１２０８、大型ＤＴＶへの表示１２０９のいずれかの機能を切り替えて動作させることができる。 FIG. 12 is a diagram showing various operation modes in the program viewing system.
As shown in (a), here, it is assumed that only the three tuners 1201 to 1203 of DTV, recorder, and CATV are used as the worst case. The three modules 1204 to 1206 connected to these can be operated by switching one of the functions of a recording operation 1207, external transmission 1208 of a video signal via a LAN, and display 1209 on a large DTV.
　（ｂ）では各種の動作形態を表に示す。動作形態１では、３つの番組の同時録画をする場合で、３つとも録画に利用されるため、端末１００への表示は、この３つのチャンネルのいずれか１つに限られる。
  動作形態２では、１つの番組を録画、１つの番組を大画面ＤＴＶで表示している場合で、ＬＡＮ経由で端末Ａ（１００）に送って表示できる番組は１つ（メイン画面）だけになる。
  動作形態３では、３つの番組をＬＡＮ経由で端末Ｂ（１００）に送ることができ、図６に示したように、中央にメイン画面１、両側にサブ画面２，３を表示することができる。 In (b), various operation modes are shown in the table. In the operation mode 1, when three programs are simultaneously recorded, since all three are used for recording, the display on the terminal 100 is limited to any one of these three channels.
In the operation mode 2, when one program is recorded and one program is displayed on the large screen DTV, only one program (main screen) can be sent to the terminal A (100) via the LAN and displayed. .
In the operation mode 3, three programs can be sent to the terminal B (100) via the LAN, and as shown in FIG. 6, the main screen 1 can be displayed in the center and the sub screens 2 and 3 can be displayed on both sides. .
　これらはチューナーリソースが３個の場合であり、例えばレコーダが同時２局録画、ＤＴＶも同様に裏番組を含めた同時２局録画ができるように、チューナーが多数あれば、端末画面に表示する画像を１画面や、表示不可になるリスクは少なくなる。ただし、それらのチューナーが各々のＡＶ機器で目いっぱい使用している場合は、端末の画面表示は上記と同じ制限を受ける。 These are cases where there are three tuner resources. For example, if there are a large number of tuners so that the recorder can perform simultaneous two-station recording and the DTV can simultaneously record two-station recording including the back program, an image to be displayed on the terminal screen. The risk of being unable to display or display one screen is reduced. However, if these tuners are fully used in each AV device, the terminal screen display is subject to the same restrictions as above.
　図１３は、携帯端末装置とＤＴＶでの放送番組の連携視聴を説明する図である。番組視聴システムでは、放送局１３００からの放送映像を２系統で受信できる。 FIG. 13 is a diagram for explaining cooperative viewing of a broadcast program on a mobile terminal device and a DTV. In the program viewing system, broadcast video from the broadcast station 1300 can be received in two systems.
　放送局１３００からの映像コンテンツは、生放送でない限りストレージ１３０１に保存されており、これを放送波（ブロードキャスト）１３０２で送信する。ＤＴＶ２３０はこれを受信して表示する。 Video content from the broadcast station 1300 is stored in the storage 1301 unless it is a live broadcast, and is transmitted by a broadcast wave (broadcast) 1302. The DTV 230 receives this and displays it.
　一方、ストレージ１３０１に保存されている映像コンテンツは、ネットワーク１３０３とルータ２４０経由で動画像ストリーム１３０４として配信され、ＤＴＶ２３０や端末２００、ＰＣ２５０では、映像のストリーミング再生が可能となる。 On the other hand, the video content stored in the storage 1301 is distributed as a moving image stream 1304 via the network 1303 and the router 240, and the DTV 230, the terminal 200, and the PC 250 can perform video streaming playback.
　ネットワーク１３０３で配信される映像は、ネットワークに負担をかけないようにデータ転送レートが制限されている。そのため、ブロードキャスト１３０２の映像に比べて画素数やフレームレート、圧縮率などが異なる設定となっている。ただし、ブロードキャスト１３０２の映像のような放送時刻の制約がなく、ユーザーは所望の時刻に受信再生することができる。 The video transfer rate of the video distributed on the network 1303 is limited so as not to put a burden on the network. Therefore, the number of pixels, the frame rate, the compression rate, and the like are different from those of the broadcast 1302 video. However, there is no restriction on the broadcast time like the image of the broadcast 1302, and the user can receive and reproduce at a desired time.
　これらの２系統の受信を連携させて視聴する例を説明する。図７（ｄ）で示したように、端末２００が現在時刻以外の番組を選択した場合、端末ではネットワーク１３０３経由で当該番組のダイジェスト／コマーシャル映像を受信することができる。これは現在時刻の番組についても同様に可能である。ユーザーは選択した番組のダイジェスト／コマーシャル映像を確認した上で、大画面ＤＴＶ２３０への表示に切り替えることができる。本機能は、端末２００だけでなくＰＣ２５０上のアプリケーションで行ってもよい。 An example in which these two systems of reception are viewed together will be described. As illustrated in FIG. 7D, when the terminal 200 selects a program other than the current time, the terminal can receive a digest / commercial video of the program via the network 1303. This is also possible for the program at the current time. The user can switch to display on the large screen DTV 230 after confirming the digest / commercial video of the selected program. This function may be performed by an application on the PC 250 as well as the terminal 200.
　図１４は、携帯端末装置とＤＴＶにおける番組選択時の映像・音声の制御の一例を示す図である。 FIG. 14 is a diagram illustrating an example of video / audio control when a program is selected in the mobile terminal device and the DTV.
　（ａ）は、端末１００の画面上で映像を左右にスクロールさせて選局を行っている状態である。この状態では、端末のスピーカー（図３の符号３０８）から出力する音量は小さくし、２つの番組の音声が混在して出力されないようにする。また、ＤＴＶ１３０が既にスピーカー１４０１から音声を出力している場合は、選局中は同様にスピーカーから出力する音量を小さく（または消音）する。すなわち、端末での画面スライド量に応じて、スピーカー１４０１の音量を変化させる。 (A) is a state where the channel is selected by scrolling the video left and right on the screen of the terminal 100. In this state, the volume output from the speaker of the terminal (reference numeral 308 in FIG. 3) is reduced so that the audio of the two programs is not mixedly output. If the DTV 130 has already output sound from the speaker 1401, the volume output from the speaker is similarly reduced (or muted) during channel selection. That is, the volume of the speaker 1401 is changed according to the screen slide amount on the terminal.
　さらに、ＤＴＶ１３０が既に映像を表示している場合は、端末の選局操作に伴って、ＤＴＶでも同時に番組切り替えを行うことになる。その場合は、ＤＴＶ１３０では切り替え途中の画面を表示せず、例えば「選局中」の文字１４０２を表示する。これにより、ＤＴＶの故障ではないことをユーザーに知らせることができる。 Further, when the DTV 130 is already displaying video, the program is switched simultaneously on the DTV as the terminal selects a channel. In this case, the DTV 130 does not display the screen during the switching, but displays, for example, a character 1402 “channel selection”. As a result, the user can be notified that the DTV is not malfunctioning.
　（ｂ）は、端末１００にて選局動作が完了した状態である。選局が完了したら、端末のスピーカーから出力する音量を通常に戻す。またＤＴＶ１３０では、スピーカー１４０１からの音量を通常に戻し、画面には選局後の映像を表示する。 (B) is a state in which the channel selection operation is completed at the terminal 100. When tuning is complete, return the volume output from the terminal speaker to normal. In DTV 130, the volume from speaker 1401 is returned to normal, and the selected video is displayed on the screen.
　図１５は、携帯端末装置とＤＴＶにおける番組選択時の映像・音声の制御の他の例を示す図である。 FIG. 15 is a diagram showing another example of video / audio control when a program is selected in the portable terminal device and the DTV.
　（ａ）は、選局中の端末１００は音声を消音にしつつ、選局先の音量が分かるように音声レベルゲージ１５０１を表示する。ＤＴＶ１３０でも、選局中はスピーカー１５０２の音声を消音にし、選局完了後は、音声レベルゲージ１５０１で設定された音量で音声を出力する。もちろん、ユーザーは音声レベルゲージ１５０１のレベルを調整できる。 (A) displays the voice level gauge 1501 so that the selected terminal 100 can mute the voice and can know the volume of the tuning destination. Also in the DTV 130, the sound of the speaker 1502 is muted during channel selection, and after the channel selection is completed, the sound is output at the volume set by the audio level gauge 1501. Of course, the user can adjust the level of the audio level gauge 1501.
　（ｂ）は、選局中の端末１００はスピーカーではなくイヤホン１５０３（図３の符号３０９に相当）から音声を出力する。ＤＴＶ１３０では、選局中はスピーカー１５０２の音声を消音にする。これによりユーザーは、イヤホン１５０３を使って選局時の音声を確認することができる。なお、イヤホン１５０３と端末１００は有線接続だけでなく、近距離無線接続（図３の符号３１８，３１８１）としてもよい。 (B), the selected terminal 100 outputs sound from the earphone 1503 (corresponding to reference numeral 309 in FIG. 3) instead of the speaker. In the DTV 130, the sound of the speaker 1502 is muted during channel selection. As a result, the user can check the sound at the time of channel selection using the earphone 1503. Note that the earphone 1503 and the terminal 100 may be not only wired connection but also short-range wireless connection ( reference numerals 318 and 3181 in FIG. 3).
　（ｃ）は、選局中の端末１００は音声を消音にするとともに、ＤＴＶ１３０でもスピーカー１５０２を消音にする。ただしＤＴＶ１３０では、それまで放送している番組が字幕付きの場合には画面に字幕１５０４を表示し、他の人の継続視聴に支障が出にくいようにする。 (C) In the selected channel 100, the terminal 100 mutes the sound, and the DTV 130 also mutes the speaker 1502. However, the DTV 130 displays subtitles 1504 on the screen when the program that has been broadcast so far has subtitles, so that it is difficult for other people to continue watching.
　以上のように、番組を選択する期間、携帯端末装置とＤＴＶの映像・音声出力を制御することで、映像や音声の乱れに伴いユーザーが受ける不快感を軽減することができる。 As described above, by controlling the video / audio output of the mobile terminal device and the DTV during the program selection period, it is possible to reduce the discomfort experienced by the user due to the disturbance of the video and audio.
