In particular, images are rich in expressiveness, and when a large number of image monitors are used, a large amount of information can be displayed, and their appeal is extremely large. As a video information display system that uses a large number of video monitors, a large number of televisions are arranged in a grid pattern, as in the case of cable TV broadcast programs, and a multi-channel broadcast program is displayed on each television. There are things that are. Also, as shown in FIG. 2, there is a system that simultaneously displays the same image on a plurality of image monitors via a distributor from an image generating device. As a system that displays different images on multiple video monitors, there is the system shown in Fig. 3. A dedicated video generation device is provided for each video monitor, and these multiple video generation devices are controlled by one video management device. By providing a video generator for each video monitor, different videos can be displayed on each video monitor. Such a system can be used in advanced ways such as displaying different images for each video monitor or expressing one video on the entire video monitor. Also, video signals used for video monitors are used as control signals for various purposes. An analog TV broadcast video signal consists of a video signal portion displayed on the TV screen and a blanking period for display control, and the blanking period includes a vertical blanking period and a horizontal blanking period. It is divided into periods. Then, a control signal for operating the broadcasting station and the like are transmitted while being superimposed on the horizontal scanning line signal in the vertical blanking period. As an example of using a video signal of a television as a control signal, there is a method of using a video signal having a special pattern as a criterion for selecting a specific video. Such a control signal can be easily created because it can be configured as a television image, but in this case, it is used to select a specific image.

発明の概要 Summary of the Invention
1台の映像生成装置からの映像を分配器を介して複数の映像モニタ一に同じ映 像を同時表示するシステムは、 簡便に構築でき、 映像生成装置の映像を変えるだ けで表示する映像をタイムリーに変更できる。 しかし、 個々の映像モニターに異 なる映像を表示できないので、 高度な映像サービスを提供することができない。 また、 複数の映像モニターに異なる映像を表示するシステムは、 個々の映像モ ニタ一に表示する映像の制御と、 全体としての映像表示の管理を行う装置が必要 になるなど、 システムが複雑になり、 その分コストが高くなる難点が存在する。 テレビに表示する映像はビデオカメラやディジタルカメラで容易に作成し送信 できるが、 帰線消去期間の水平走査線に制御信号を重畳するためには、 特殊な装 置が必要になり、 テレビに表示する映像との同期制御を行うためには更に複雑な 装置や手順が必要になるという問題点がある。 また、 M P E G— 2方式のデジタルテレビ放送ではテレビ映像の表示制御のた めのプログラム仕様情報 （P S I ) やサービス情報 （S I ) が映像信号とは別の 信号形式で送信されている。 これらの制御信号を利用するためには、 特殊な信号 編集システムや信号の合成器が必要になるという問題点がある。 通常、 N T S C方式のテレビ放送では毎秒 3 0枚の映像を送信しており、 この 映像情報をディジタル信号で送信する場合、 映像の圧縮技術を活用しても、 デ一 タ量が非常に大きいために、 高速伝送路を用いても N T S C方式のテレビ放送と 同じ映像の品質を確保することは容易ではない。 音声帯域の信号を送信する有線及び電波の伝送路は安価に使用できるが、 動画 映像の伝送が難しいため、 これら低速の信号伝送路を使用した映像情報の利用は 少ない。 有線及び電波の伝送路を使用した静止画伝送装置は専ら遠隔地間の静止 画伝送に用いられ、 これを複数の映像モニタ一に接続して映像の情報サービスを 行う例は見られない。 またテレビ映像を音声帯域の電波信号で送信する S S T V (スロースキャン T V) ゃテレビ電話を使用し映像を利用した情報サ一ビスがあ るが、 あまり普及はしていない。 以上のような状況に鑑み、 本発明は、 複数の映像モニターを使用する映像情報 サ一ビスシステムにおいて、 個々の映像モニター毎に、 特定の静止画や動画の表 示制御や音声の制御を簡便に行えるシステムを提供することを目的とする。また、 本発明は、 より効果的な映像情報サービスを行うために必要になる、 付属の装置 の制御も簡便に行えるシステムを提供することも目的としている。 映像の分配及び表示制御システムは、 制御映像生成装置と、 複数の映像制御装 置と、 複数の映像モニタ一と前記制御映像生成装置と前記複数の映像制御装置と 前記複数の映像モニターの各装置間の映像の伝送路から構成される。 制御映像生 成装置が出力する映像は、 映像モニターに表示する表示映像と、 映像制御装置を 指定する識別番号及び制御コマンドからなる制御映像の 2種で構成される。 制御 映像生成装置は制御映像の後に表示映像を配置し、 同一の映像伝送路を使用して 連続送信することにより、 この映像伝送路に接続された複数の映像制御装置に制 御映像と表示映像を分配する。 映像制御装置は、 制御映像生成装置から受信する 制御映像を検出し、 識別番号及び制御コマンドの内容を解析し、 識別番号が自局 宛の場合は制御コマンドの内容に従って、 映像を記憶 '蓄積 '再生し、 映像モニ ターに表示する。 本発明のシステムは制御映像生成装置と、 複数の映像制御装置と、 複数の映像 モニターと前記制御映像生成装置と前記複数の映像制御装置と前記複数の映像モ 二ターの各装置間の映像の伝送路から構成されるが、 映像伝送路に複数の映像制 御装置が接続できない場合は、 制御映像生成装置の出力映像伝送路に分配器を設 け、 分配器の出力映像伝送路に映像制御装置が接続される。 制御映像生成装置は映像制御装置を制御する制御映像と表示映像を映像伝送路 に出力する。 制御映像生成装置としてはパーソナルコンピュータや、 ビデオテー プ装置、 ビデオ C Dや D V D等のビデオ出力機器が使用できる。 映像制御装置は、 映像伝送路から受信する制御映像を解析し、 指定された制御 動作を行う。 例えば当該映像制御装置を指定した制御映像を受信した場合には、 その映像制御装置は制御コマンドを解析する。 その制御コマンドが後続の映像を 記憶部に記憶し、 それを表示する指令であった場合には、 映像制御装置は続いて 送られてくる表示映像を受信し、 表示映像をフレームメモリーや磁気ディスク装 置等に記憶蓄積し、 再生表示を行う。 映像伝送路は、 映像信号がベースバンドの電気信号で送信される場合や、 アナ 口グ信号またはデジタル信号のテレビジョン電波信号に変調されて送信される場 合や、 レ一ザ一光線や赤外線などの光信号に変換されて伝送される場合があり、 映像信号の伝送形態に従って、 メタル線伝送路、 電波伝送路、 光ファイバ一伝送 路及び赤外線伝送路が利用される。 制御映像は、 映像信号の映像表示部分を利用して構成する。 映像が N T S C方 式のテレビジョン映像である場合、 テレビ放送では 5 2 5本の水平走査線で 1画 面のフレーム信号を構成している。 この 1フレームの映像は 2フィールドの映像 画面による飛び越し操作でテレビ画面上に 1画面として表示されている。 例えば 1フレームを構成する最初の奇数フィールドは 1番目の水平走査線信号から 2 6 3番目の水平走査線信号の前半部までで構成され、 第 1番目の水平走査線信号か ら 2 2番目の水平走査線の前半部分までが垂直帰線消去期間で、 それ以降が映像 表示部分になる。 映像表示部分である 2 3番目から 2 6 2番目までの 2 4 0本の 水平走査線を使用して、 制御映像を構成することができる。 偶数フィールドは 2 6 3番目の水平走査線信号の後半部から 5 2 5番目の水平走査線信号で構成さ れ、 奇数フィ一ルドと同様に映像表示部分の 2 4 0本の水平走査線を使用して、 制御映像を構成することができる。 また制御映像は 1枚の映像として構成することができる。 その構成の 1つの例 を下記に詳細に記述する。 下記の例では白と黒のスリット列から発生するのパル スの数を制御コマンドゃ識別番号に対応させた例であるが、 商品に付加されるバ —コードのように白と黒のバーの数と幅を制御コマンドゃ識別番号に対応させて も良い。 A system that simultaneously displays the same image on multiple video monitors via a distributor from the image from one image generation device can be easily constructed, and the image to be displayed by simply changing the image of the image generation device is displayed. Can be changed in a timely manner. However, since different images cannot be displayed on individual image monitors, advanced image services cannot be provided. In addition, a system that displays different images on multiple video monitors requires a device that controls the images displayed on each video monitor and manages the overall image display. However, there is a disadvantage that the cost is increased accordingly. Images to be displayed on a TV can be easily created and transmitted by a video camera or digital camera.However, a special device is required to superimpose control signals on horizontal scanning lines during the blanking interval, and display on a TV There is a problem that more complicated devices and procedures are required to perform synchronization control with the synchronized video. In digital television broadcasting of the MPEG-2 system, program specification information (PSI) and service information (SI) for controlling display of television images are transmitted in a signal format different from the video signal. In order to use these control signals, there is a problem that a special signal editing system and a signal synthesizer are required. Normally, 30 frames of video are transmitted per second in NTSC television broadcasting.When transmitting this video information as digital signals, the amount of data is very large even if video compression technology is used. In addition, it is not easy to ensure the same video quality as NTSC television broadcasting even when using high-speed transmission lines. Wired and radio transmission lines for transmitting signals in the audio band can be used at low cost, but it is difficult to transmit video images, so video information using these low-speed signal transmission lines is rarely used. Still image transmission devices using wired and radio wave transmission lines are used exclusively for still image transmission between remote locations, and are connected to multiple video monitors to provide video information services. There is no example of doing this. In addition, there is an information service that uses video using a videophone, such as SSTV (slow scan TV), which transmits TV video using radio signals in the audio band, but it is not widely used. In view of the circumstances described above, the present invention provides a video information service system using a plurality of video monitors, which makes it easy to control display of a specific still image or moving image and control of audio for each video monitor. It is an object of the present invention to provide a system that can be used in a computer. Another object of the present invention is to provide a system that can easily control attached devices, which is necessary for providing more effective video information services. The video distribution and display control system includes a control video generation device, a plurality of video control devices, a plurality of video monitors, the control video generation device, the plurality of video control devices, and each of the plurality of video monitors. It consists of a video transmission path between them. The video output by the control video generator consists of two types: a display video displayed on a video monitor, and a control video consisting of an identification number specifying the video control device and a control command. The control video generation device arranges the display video after the control video and continuously transmits it using the same video transmission line, so that the control video and the display video are transmitted to the multiple video control devices connected to this video transmission line. Distribute. The video control device detects the control video received from the control video generation device, analyzes the identification number and the content of the control command, and stores the video according to the content of the control command when the identification number is addressed to its own station. Play back and display on the video monitor. The system of the present invention includes a control video generation device, a plurality of video control devices, a plurality of video monitors, the control video generation device, the plurality of video control devices, and the video of each of the plurality of video monitors. It consists of a transmission line, but if multiple video controllers cannot be connected to the video transmission line, a distributor is installed on the output video transmission line of the control video generation device, and video control is performed on the output video transmission line of the distributor. The device is connected. The control video generation device outputs a control video and a display video for controlling the video control device to a video transmission path. A personal computer, videotape, etc. Video devices such as video CDs and DVDs can be used. The video control device analyzes the control video received from the video transmission path and performs a specified control operation. For example, when receiving a control video specifying the video control device, the video control device analyzes the control command. If the control command is a command to store the subsequent image in the storage unit and display it, the image control device receives the subsequently transmitted display image, and stores the display image in the frame memory or the magnetic disk. The data is stored and stored in the device, etc., and played back. The video transmission path is used when the video signal is transmitted as a baseband electrical signal, when it is transmitted after being modulated into an analog or digital television signal, or when a laser beam or infrared light is transmitted. In some cases, a metal wire transmission line, a radio wave transmission line, an optical fiber transmission line, and an infrared transmission line are used according to the video signal transmission form. The control video is configured using the video display portion of the video signal. If the video is an NTSC-type television video, a frame signal of one screen is composed of 525 horizontal scanning lines in television broadcasting. This one-frame video is displayed as one screen on the TV screen by a skip operation using a two-field video screen. For example, the first odd field that constitutes one frame consists of the first horizontal scanning line signal to the first half of the 26th horizontal scanning line signal, and the first horizontal scanning line signal to the second half of the second horizontal scanning line signal. Up to the first half of the horizontal scanning line is the vertical blanking period, and the rest is the video display part. The control video can be composed using 240 horizontal scanning lines from the 23rd to the 26th, which is the video display part. The even field consists of the second and fifth horizontal scanning line signals from the second half of the 23rd horizontal scanning line signal, and the 240 horizontal scanning lines of the video display portion are arranged in the same manner as the odd field. Can be used to compose the control video. The control video can be configured as one video. One example of that configuration is described in detail below. In the example below, the pallets generated from the white and black slit rows This is an example in which the number of bars corresponds to the control command ゃ identification number, but the number and width of the white and black bars, such as the bar code added to the product, may correspond to the control command ゃ identification number. .
2 4 0本の水平走査線を連続する 2 0本を 1つのグループにすると 1 2のダル ープに分割できる。 最初のグループで制御映像の開始を示す映像を構成し、 2番 目のグループで特定の映像制御装置の識別番号を指定する映像を構成し、 3番目 のグループで制御コマンドを指定する映像を構成することができる。 4番目のグ ループの映像で制御コマンドの動作タイミングを指示することができる。同様に、 5番目以降のグループも異なる目的に使用することができる。 制御映像の終了を 示す映像を最後に配置する。 制御信号として使用しない映像部分には、 制御映像 の内容を表す文を表示するのに使用できる。 第 1番のグループに含まれる全ての水平走査線が 3 0個の白パルス信号で構成 される場合を制御映像の判定基準とすることができる。 このような映像は黒地の 画面で水平走査線の 2 3番目から 4 2番目までの領域に、 3 0個の白の矩形バー を水平に配置して描画することにより作成できる。 同様にして、 第 2グループか ら第 4グループの映像信号も形成することができる。 制御映像を送信する場合、連続した複数枚の映像として送信することができる。 If 24 consecutive horizontal scanning lines are grouped into 20 groups, they can be divided into 12 groups. The first group configures the video that indicates the start of the control video, the second group configures the video that specifies the identification number of the specific video control device, and the third group configures the video that specifies the control command can do. The operation timing of the control command can be indicated by the video of the fourth group. Similarly, the fifth and subsequent groups can be used for different purposes. The video indicating the end of the control video is placed last. The video part not used as a control signal can be used to display a sentence indicating the content of the control video. A case where all the horizontal scanning lines included in the first group are composed of 30 white pulse signals can be used as a criterion for the control image. Such an image can be created by drawing 30 white rectangular bars horizontally in the 23rd to 42nd horizontal scanning lines on a black screen. Similarly, video signals of the second to fourth groups can be formed. When transmitting the control video, it can be transmitted as a plurality of continuous video.
1番目に映像の開始を示す映像、 2番目に映像制御装置の識別番号の映像、 3番 目に制御コマンドの映像、 4番目に制御コマンドの動作タイミングを表す映像、 5番目に制御映像の終わりを示す映像を並べ、 5枚の映像を連続して送信する方 法がある。 低データ量の M P E G— 2信号に変換して制御映像を伝送する場合、 Iピクチャー、 Pピクチャー、 Bピクチャーで構成される複数枚の映像として制 御映像を送信することができ、 映像制御装置は制御映像の開始と終了を示す映像 を検出することにより複数枚の映像信号から有効な制御映像を取出すことができ る。 電話回線等の低速度の伝送路で制御映像を 1枚の映像として伝送する場合、 完 全な映像として制御映像を送信するのに時間がかかるが、 映像制御装置は制御映 像の開始と終了を示す映像を検出することにより受信した映像から有効な制御映 像を取出すことができる。 The first is the video that indicates the start of the video, the second is the video with the identification number of the video controller, the third is the video of the control command, the fourth is the video that indicates the operation timing of the control command, and the fifth is the end of the control video There is a method of arranging the images that indicate, and transmitting five images continuously. When transmitting control video by converting it to a low data amount MPEG-2 signal, the control video can be transmitted as a plurality of videos consisting of I picture, P picture, and B picture. By detecting the video indicating the start and end of the control video, an effective control video can be extracted from a plurality of video signals. When transmitting control video as a single video over a low-speed transmission line such as a telephone line, Although it takes time to transmit the control video as a complete video, the video control device can extract a valid control video from the received video by detecting the video that indicates the start and end of the control video.

FIG. 7 shows an example of a video output by the control video generation device (1), in which a control video and a display video are combined to form a continuous video. A display image to be controlled is arranged after the control image, and is continuously transmitted using the same video transmission line, so that a plurality of video control devices (2 ) Can simultaneously distribute control information and video information. The control video and the display video do not necessarily need to be paired. For example, the first video indicates that it is a control video, and the second video specifies a specific video control device (2). The control operation can be specified by the third image. Similarly, the displayed image may be used as a plurality of images such as a still image for the first image and a moving image for the second image. Next, a procedure for displaying a desired image on the video monitor (3) connected to the second video control device (2) will be described with reference to the system shown in FIG. First, the control video generation device (1) outputs a control video addressed to the second video control device (2). This control video is transmitted to four video controllers (2). The video signals input to the four video control units (2) are amplified by the respective video signal amplification / distribution units (2 1) and sent to the detection units (2 2). The detection unit (22) detects whether the received video is a control video, and if it is a control video, analyzes the identification number. Since the second video control device (2) has received the control video having the identification number addressed to itself, the control CPU (23) analyzes the control command included in the control video and performs a predetermined operation. Becomes The video control device other than the second video control device (2) detects that the control video is not intended for itself, stops the process, and waits for the next control video to arrive. If this control command instructs that the subsequent display video be captured as a one-frame still image after twice the unit time, stored in the storage device, and displayed on the video monitor (3), The procedure and operation are as follows. After outputting the control video, the control video generator (1) outputs a display video that is sufficiently longer than the capture time specified by the video controller (2), for example, three times as long as the unit time. The control CPU (23) of the second video controller (2) sets the set value of the built-in timer to twice the unit time. When the built-in timer generates an interrupt signal after the lapse of the set time after a doubling of the unit time, the control CPU (23) sends a recording start signal to the video signal storage (25). The video signal storage section (25) captures one frame of video while synchronizing with the video synchronization signal. Next, the control CPU (23) sends a reproduction output signal of the recorded video to the video signal storage (25). The video signal storage unit (25) reproduces and outputs the specified video according to the control signal of the control CPU (23). Next, the control CPU (23) sends a control signal for selecting the specified video signal and outputting it to the video monitor (3) to the display video selection control unit (27). The display video selection control unit (27) switches the switch according to the control signal from the control CPU (23) and outputs the specified video signal to the output circuit. As a result of the above control operation, the specified video is displayed on the video monitor (3) connected to the output circuit. In the same procedure, the second video control device (2) can store the second video as a still image of one frame in the second storage unit. By sending a command to alternately display the first still image and the second still image at regular time intervals, the blinking display using two still images is displayed on the video monitor (3). Can be done.
