　一般的な表示装置において、リモコン送信機から同一の制御信号の受信を繰り返すことで表示機能の状態のＯＮ／ＯＦＦを切り替えるトグル動作を行うものがある。例えば、リモコン送信機における電源のＯＮ／ＯＦＦボタンが同一であって、このＯＮ／ＯＦＦボタンが押下されたことにより送信される制御信号に基づき、表示装置が電源の切り替えを行う。
　一方、音量調整用のボタンのように、同一のボタンが押下されて、この操作による同一の制御信号を表示装置が連続的に受信した場合、機能の切り替えではなく、設定状態の連続的な変更を行う場合もある。
　このように、制御信号を連続して受信することによる表示装置の制御が異なる場合、受信した制御信号に応じて、次にリモコン送信機から受信する制御信号を制限するものがある（例えば、特許文献１参照）。 Some general display devices perform a toggle operation for switching ON / OFF of a display function state by repeatedly receiving the same control signal from a remote control transmitter. For example, the power supply ON / OFF buttons in the remote control transmitter are the same, and the display device switches the power supply based on a control signal transmitted when the ON / OFF button is pressed.
On the other hand, when the same button is pressed and the display device continuously receives the same control signal by this operation, such as a volume adjustment button, the setting state is not changed continuously, but the setting state is continuously changed. May be performed.
As described above, when the control of the display device by continuously receiving the control signal is different, there is one that restricts the next control signal received from the remote control transmitter according to the received control signal (for example, patents). Reference 1).

　しかしながら、複数の表示装置が直列的に接続されている場合、途中の一台で受信ミスが発生した場合、それ以降の表示装置に制御信号が伝送されないため、これら複数の表示装置を統括的に制御することができない問題がある。
　例えば、複数の表示装置のうち一の表示装置がリモコン送信機から電源ＯＮ／ＯＦＦを示す制御信号を受信した際、途中の一台で受信ミスが発生し、以降の表示装置に対して、電源ＯＮ／ＯＦＦを示す制御信号が伝送されない場合がある。この場合、電源ＯＮ／ＯＦＦを示す制御信号を受信した表示装置では電源がＯＮされるももの、受信ミスが発生した表示装置以降の表示装置においては電源がＯＦＦのままである。これに続けて、リモコン送信機から電源ＯＮ／ＯＦＦを示す制御信号が送信されると、現時点において電源がＯＮされている表示装置は電源がＯＦＦされ、電源がＯＦＦされている表示装置は電源がＯＮされる。よって、複数の表示装置が連動して動作されない問題がある。 However, when a plurality of display devices are connected in series, if a reception error occurs in one of the units, a control signal is not transmitted to the subsequent display devices. There is a problem that cannot be controlled.
For example, when one display device out of a plurality of display devices receives a control signal indicating power ON / OFF from a remote control transmitter, a reception error occurs in one of the devices, and power is supplied to the subsequent display devices. There is a case where a control signal indicating ON / OFF is not transmitted. In this case, the display device that has received the control signal indicating the power ON / OFF is turned on, while the display device after the display device in which the reception error has occurred remains off. Subsequently, when a control signal indicating power ON / OFF is transmitted from the remote control transmitter, the display device that is currently turned on is turned off, and the display device that is turned off is turned on. Turned on. Therefore, there is a problem that a plurality of display devices are not operated in conjunction with each other.

　次に、発明を実施するための一形態について図面を参照して詳細に説明する。
　図１は、本実施形態に係る表示システムの一例を示す図である。
　図１に示す通り、表示システムは、直列的に接続されている複数の表示装置（以下、ディスプレイという）１～９と、ディスプレイ１に制御信号であるリモコンコードを送信するリモコン送信機１０を備える。このディスプレイ１～９は、例えば、接続ケーブルを介して、符号１～９の順番通り、各ディスプレイは、１つ小さい数の符号のディスプレイに従属して接続されている。つまり、各ディスプレイは、１つ小さい数の符号のディスプレイから受信した制御信号に基づき動作する。 Next, an embodiment for carrying out the invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram illustrating an example of a display system according to the present embodiment.
As shown in FIG. 1, the display system includes a plurality of display devices (hereinafter referred to as displays) 1 to 9 connected in series, and a remote control transmitter 10 that transmits a remote control code as a control signal to the display 1. . For example, the displays 1 to 9 are connected via a connection cable in the order of reference numerals 1 to 9 depending on a display having a smaller number of signs. That is, each display operates based on a control signal received from a display having a code having a smaller number.
　リモコン送信機１０は、例えば、赤外線によるＩＲ（　Ｉｎｆｒａｒｅｄ　）信号にリモコンコードをのせてディスプレイ１に送信する。このリモコンコードは、リモコン送信機１０からディスプレイ１～９に対して指示される制御情報（リモコン情報）を含む。
　このディスプレイ１は、リモコン送信機１０から送信されるリモコンコードを受信し、このリモコンコードに基づき、伝送コード１００を作成する。このディスプレイ１は、作成した伝送コード１００を接続ケーブルで接続されているディスプレイ２に送信する。
　このディスプレイ２は、ディスプレイ１から受信した伝送コード１００に基づき、伝送コード１００の内容を判断する。このディスプレイ２は、判断結果に基づき伝送コード２００を作成して、ディスプレイ３に送信する。 The remote control transmitter 10 transmits a remote control code on an IR (Infrared) signal using infrared rays, for example, to the display 1. This remote control code includes control information (remote control information) instructed from the remote control transmitter 10 to the displays 1 to 9.
The display 1 receives the remote control code transmitted from the remote control transmitter 10 and creates a transmission code 100 based on the remote control code. The display 1 transmits the created transmission code 100 to the display 2 connected by a connection cable.
The display 2 determines the content of the transmission code 100 based on the transmission code 100 received from the display 1. The display 2 creates a transmission code 200 based on the determination result and transmits it to the display 3.
　このようにして、ディスプレイ３～８は、それぞれ、受信する伝送コード２００～７００の内容を判断して、判断結果に基づき伝送コード３００～８００を作成し、接続されているディスプレイ４～９に送信する。ディスプレイ９は、送信先のディスプレイが接続されていないため、受信する伝送コード８００の内容を判断するものの、伝送コードを作成して送信することはしない。
　また、これらディスプレイ１～９は、それぞれ表示部を備えており、判断結果に基づき表示部を制御する。
　このように、ディスプレイ１～９は、受信した伝送コードの内容を判断した後に各表示部を制御するとともに、判断結果に応じた伝送コードを生成し、送信先のディスプレイに対して送信する。
　なお、ディスプレイ１～９は、複数であればよく９台に限定されない。また、接続ケーブルは、シリアル形式で情報を伝送するものが利用可能である。 In this way, the displays 3 to 8 determine the contents of the received transmission codes 200 to 700, respectively, create transmission codes 300 to 800 based on the determination results, and send them to the connected displays 4 to 9 To do. Since the display 9 is not connected to the transmission destination display, the display 9 determines the content of the transmission code 800 to be received, but does not create and transmit the transmission code.
Each of the displays 1 to 9 includes a display unit, and controls the display unit based on the determination result.
As described above, the displays 1 to 9 control the respective display units after determining the contents of the received transmission code, generate a transmission code corresponding to the determination result, and transmit the transmission code to the transmission destination display.
Note that the number of displays 1 to 9 is not limited to nine as long as they are plural. A connection cable that transmits information in a serial format can be used.

Based on the operation signal output from the operation unit 12, the remote control transmission unit 11 transmits a remote control code indicating the remote control information as the operation content to the display 1 on the IR signal. The operation unit 12 receives an operation from the user and outputs an operation signal corresponding to the operation to the remote control transmission unit 11.
　送信側のディスプレイであるディスプレイ１は、計時部３１と、受信部３２と、コード処理部３３と、制御部３４と、表示部３５と、送信部３６とを備える。
　計時部３１は、受信部３２が直前に受信したリモコンコードを受信した時から、予め決められている受信待ち時間を計時して、受信待ち時間が経過したことを示す信号を受信部３２に出力する。 The display 1 that is a display on the transmission side includes a timer 31, a receiver 32, a code processor 33, a controller 34, a display 35, and a transmitter 36.

　受信部３２は、計時部３１から受信待ち時間が経過したことを示す信号を受信したか否かを判断し、受信待ち時間が経過したことを判断した場合、リモコン送信機１０から送信されるリモコンコードを受信する。この受信部３２は、受信したリモコンコードをコード処理部３３に出力する。 The receiving unit 32 determines whether or not a signal indicating that the reception waiting time has elapsed has been received from the time measuring unit 31, and when determining that the reception waiting time has elapsed, the remote control transmitted from the remote control transmitter 10. Receive code. The receiving unit 32 outputs the received remote control code to the code processing unit 33.
　コード処理部３３は、コード判断部３３１と、コード生成部３３２を含む。
　コード判断部３３１は、受信部３２から出力されるリモコンコードの内容を判断して、このリモコンコードが示すリモコン情報を制御部３４およびコード生成部３３２に出力する。
　コード生成部３３２は、受信部３２から出力されるリモコンコードに基づき、伝送コード（例えば、伝送コード１００）を作成する。この伝送コード１００は、図３に示すように、コード生成部３３２によって決められたコード間隔Ｇ１でつながっている複数の制御コード１～５からなる。なお、このコード間隔Ｇ１は、送信部３６から送信される際の制御コード間の待ち時間であり、例えば、１００ｍｓの長さである。
　具体的に説明すると、このコード生成部３３２は、リモコンコードの内容を示すリモコン情報をそれぞれ含む制御コード１～５を生成する。この制御コード１～５は、全て同じリモコン情報を含む。コード生成部３３２は、これら制御コード１～５が少なくともコード間隔Ｇ１をあけて送信部３６から送信されることを示す送信タイミング情報を制御コード１～５に対応づけた伝送コード１００を送信部３６に出力する。 The code processing unit 33 includes a code determination unit 331 and a code generation unit 332.
The code determination unit 331 determines the content of the remote control code output from the reception unit 32 and outputs the remote control information indicated by the remote control code to the control unit 34 and the code generation unit 332.
The code generation unit 332 creates a transmission code (for example, the transmission code 100) based on the remote control code output from the reception unit 32. As shown in FIG. 3, the transmission code 100 is composed of a plurality of control codes 1 to 5 connected at a code interval G1 determined by the code generator 332. The code interval G1 is a waiting time between control codes when transmitted from the transmission unit 36, and has a length of 100 ms, for example.
More specifically, this code generation unit 332 generates control codes 1 to 5 each including remote control information indicating the contents of the remote control code. The control codes 1 to 5 all include the same remote control information. The code generation unit 332 transmits the transmission code 100 in which the transmission timing information indicating that these control codes 1 to 5 are transmitted from the transmission unit 36 at least with the code interval G1 is associated with the control codes 1 to 5. Output to.
　制御部３４は、コード判断部３３１から出力されるリモコン情報に基づき表示部３５を制御する。
　表示部３５は、制御部３４の制御に従い、例えば表示部３５の電源をＯＮする。また、表示部３５は、制御部３４の制御に従い、メモリから読み出した画像データに基づく画像を表示し、あるいは、ケーブルや無線通信を介して接続される画像再生装置から送信される画像データを受信して当該画像データに基づく画像を表示することができる。
　送信部３６は、コード生成部３３２から出力された伝送コード１００をディスプレイ２に送信する。 The control unit 34 controls the display unit 35 based on the remote control information output from the code determination unit 331.
The display unit 35 turns on the power of the display unit 35, for example, according to the control of the control unit 34. In addition, the display unit 35 displays an image based on the image data read from the memory, or receives image data transmitted from an image reproduction device connected via a cable or wireless communication, under the control of the control unit 34. Thus, an image based on the image data can be displayed.
The transmission unit 36 transmits the transmission code 100 output from the code generation unit 332 to the display 2.
　受信側のディスプレイであるディスプレイ２は、計時部５１と、受信部５２と、コード処理部５３と、制御部５４と、表示部５５と、送信部５６とを備える。なお、これらの構成は、ディスプレイ１と同様の機能を有し、ここでは、受信側のディスプレイとしての機能について、具体的に説明する。 The display 2 that is a display on the receiving side includes a timer 51, a receiver 52, a code processor 53, a controller 54, a display 55, and a transmitter 56. Note that these configurations have the same function as the display 1, and here, the function as a display on the receiving side will be specifically described.
　受信部５２は、ディスプレイ１から送信される伝送コード１００を受信し、コード処理部５３に出力する。この受信部５２は、伝送コード１００に含まれる制御コード１～５を、順次受信する。
　計時部５１は、受信部５２が伝送コード１００を受信する際、伝送コード１００に含まれる制御コード１～５を受信する間隔（時間）を計時し、この制御コード１～５を受信する際のそれぞれの間隔を示す情報をコード処理部５３に出力する。 The receiving unit 52 receives the transmission code 100 transmitted from the display 1 and outputs it to the code processing unit 53. The receiving unit 52 sequentially receives the control codes 1 to 5 included in the transmission code 100.
When the receiving unit 52 receives the transmission code 100, the time measuring unit 51 measures an interval (time) for receiving the control codes 1 to 5 included in the transmission code 100, and receives the control codes 1 to 5. Information indicating each interval is output to the code processing unit 53.
　コード処理部５３は、コード判断部５３１と、コード生成部５３２を含む。
　コード判断部５３１は、受信部５２から出力される伝送コードと、計時部５１から出力される制御コード１～５を受信する際のそれぞれの間隔を示す情報に基づき、伝送コードの内容を判断して、この伝送コードが示すリモコン情報を制御部５４およびコード生成部５３２に出力する。
　具体的に説明すると、コード判断部５３１は、制御コード１～５を受信する際のそれぞれの間隔を示す情報に基づき、予め決められたコード受信間隔（時間）Ｇ２以内で、直前に受信した制御コードに連続して受信する制御コードを、同一の伝送コードに含まれる制御コードと判断する。
　このコード判断部５３１は、この同一の伝送コードと判断された複数の制御コード１～５に基づき、各制御コード１～５が示すリモコン情報を得て、同じ内容を示すリモコン情報のうち最もその数が多いリモコン情報を、伝送コード１００が示すリモコン情報であると判断する。このコード判断部５３１は、伝送コード１００が示すリモコン情報を判断した場合、この判断結果であるリモコン情報を制御部５４およびコード生成部５３に出力する。
　なお、同じ内容を示すリモコン情報の数が最も多くなるリモコン情報がない場合、コード判断部５３１は、判断できないことを示すエラー情報を制御部５４およびコード生成部５３２に出力する。 The code processing unit 53 includes a code determination unit 531 and a code generation unit 532.
The code determining unit 531 determines the content of the transmission code based on the transmission code output from the receiving unit 52 and the information indicating the intervals when receiving the control codes 1 to 5 output from the time measuring unit 51. The remote control information indicated by the transmission code is output to the control unit 54 and the code generation unit 532.
More specifically, the code determination unit 531 controls the control received immediately before within the predetermined code reception interval (time) G2 based on the information indicating the intervals when receiving the control codes 1 to 5. A control code continuously received in the code is determined as a control code included in the same transmission code.
The code determination unit 531 obtains remote control information indicated by the control codes 1 to 5 based on the plurality of control codes 1 to 5 determined to be the same transmission code, and most of the remote control information indicating the same content. It is determined that remote control information having a large number is remote control information indicated by the transmission code 100. When the code determination unit 531 determines the remote control information indicated by the transmission code 100, the code determination unit 531 outputs the remote control information that is the determination result to the control unit 54 and the code generation unit 53.
When there is no remote control information having the largest number of remote control information indicating the same content, the code determination unit 531 outputs error information indicating that determination cannot be made to the control unit 54 and the code generation unit 532.
　ここで、図４を参照して、このコード判断部５３１の判断例について説明する。
　例えば、同一の伝送コードに含まれる制御コード１～３のリモコン情報が「ａ」、制御コード４、５のリモコン情報が「ｍｉｓｓ（不明）」である場合（ケース１）、同じ内容を示すリモコン情報の数が最も多いリモコン情報は、リモコン情報「ａ」である。よって、コード判断部５３１は、判断結果としてリモコン情報「ａ」を制御部５４およびコード生成部５３２に出力する。
　また、同一の伝送コードに含まれる制御コード１、２のリモコン情報が「ａ」、制御コード３のリモコン情報が「ｂ」、制御コード４のリモコン情報が「ｃ」、制御コード５のリモコン情報が「ｍｉｓｓ（不明）」である場合（ケース２）、同じ内容を示すリモコン情報の数が最も多いリモコン情報は、リモコン情報「ａ」である。よって、コード判断部５３１は、判断結果としてリモコン情報「ａ」を制御部５４およびコード生成部５３２に出力する。
　一方、同一の伝送コードに含まれる制御コード１のリモコン情報が「ｍｉｓｓ（不明）」、制御コード２、３のリモコン情報が「ｂ」、制御コード４のリモコン情報が「ａ」、制御コード５のリモコン情報が「ｃ」である場合（ケース３）、同じ内容を示すリモコン情報の数が最も多いリモコン情報は、リモコン情報「ｂ」である。よって、コード判断部５３１は、判断結果としてリモコン情報「ｂ」を制御部５４およびコード生成部５３２に出力する。 Here, with reference to FIG. 4, a determination example of the code determination unit 531 will be described.
For example, when the remote control information of the control codes 1 to 3 included in the same transmission code is “a” and the remote control information of the control codes 4 and 5 is “miss (unknown)” (case 1), the remote control indicating the same contents The remote control information with the largest number of information is remote control information “a”. Therefore, the code determination unit 531 outputs the remote control information “a” as a determination result to the control unit 54 and the code generation unit 532.
The remote control information of the control codes 1 and 2 included in the same transmission code is “a”, the remote control information of the control code 3 is “b”, the remote control information of the control code 4 is “c”, and the remote control information of the control code 5 Is “miss (unknown)” (case 2), the remote control information with the largest number of remote control information indicating the same content is the remote control information “a”. Therefore, the code determination unit 531 outputs the remote control information “a” as a determination result to the control unit 54 and the code generation unit 532.
On the other hand, the remote control information of the control code 1 included in the same transmission code is “miss (unknown)”, the remote control information of the control codes 2 and 3 is “b”, the remote control information of the control code 4 is “a”, and the control code 5 If the remote control information is “c” (case 3), the remote control information having the largest number of remote control information indicating the same content is the remote control information “b”. Therefore, the code determination unit 531 outputs the remote control information “b” as a determination result to the control unit 54 and the code generation unit 532.
　また、ケース４のように、同一の伝送コードに含まれる全ての制御コード１～５のリモコン情報が異なる場合、コード判断部５３１は、リモコン情報が「ｍｉｓｓ（不明）」であると判断し、判断結果としてリモコン情報「ｍｉｓｓ（不明）」を制御部５４およびコード生成部５３２に出力する。
　さらに、ケース５のように、同じ内容を示すリモコン情報の数が最も多いリモコン情報が、リモコン情報「ａ」およびリモコン情報「ｂ」のように２以上ある場合、コード判断部５３１は、リモコン情報が「ｍｉｓｓ（不明）」であると判断し、判断結果としてリモコン情報「ｍｉｓｓ（不明）」を制御部５４およびコード生成部５３２に出力する。
　また、ケース６のように、同じ内容を示すリモコン情報の数が最も多いリモコン情報が、リモコン情報「ｍｉｓｓ（不明）である場合、コード判断部５３１は、リモコン情報が「ｍｉｓｓ（不明）」であると判断し、判断結果としてリモコン情報「ｍｉｓｓ（不明）」を制御部５４およびコード生成部５３２に出力する。 If the remote control information of all control codes 1 to 5 included in the same transmission code is different as in case 4, the code determination unit 531 determines that the remote control information is “miss (unknown)”, and As a determination result, remote control information “miss (unknown)” is output to the control unit 54 and the code generation unit 532.
Further, as in case 5, when there are two or more remote control information having the largest number of remote control information indicating the same content, such as remote control information “a” and remote control information “b”, the code determining unit 531 Is “miss (unknown)”, and remote control information “miss (unknown)” is output to the control unit 54 and the code generation unit 532 as a determination result.
Further, as in case 6, when the remote control information having the largest number of remote control information indicating the same content is the remote control information “miss (unknown)”, the code determination unit 531 indicates that the remote control information is “miss (unknown)”. The remote control information “miss (unknown)” is output to the control unit 54 and the code generation unit 532 as a determination result.
　コード生成部５３２は、コード判断部５３１から出力される判断結果に基づき、伝送コード（例えば、制御コード２００）を作成する。この伝送コード２００は、伝送コード１００と同様に、コード生成部５３２によって決められたコード間隔Ｇ１でつながっている複数の制御コード１～５からなる。
　このコード生成部５３２は、コード判断部５３１によって得られた判断結果であるリモコン情報を示す制御コード１～５を生成する。つまり、この制御コード１～５は、全て同じリモコン情報（判断結果）を含む。コード生成部５３２は、これら制御コード１～５がコード間隔Ｇ１をあけて送信部３６から送信されることを示す送信タイミング情報を制御コード１～５に対応づけた伝送コード２００を送信部３６に出力する。 The code generation unit 532 creates a transmission code (for example, the control code 200) based on the determination result output from the code determination unit 531. Similar to the transmission code 100, the transmission code 200 includes a plurality of control codes 1 to 5 connected at a code interval G1 determined by the code generation unit 532.
The code generation unit 532 generates control codes 1 to 5 indicating remote control information that is a determination result obtained by the code determination unit 531. That is, the control codes 1 to 5 all include the same remote control information (judgment result). The code generation unit 532 transmits to the transmission unit 36 a transmission code 200 in which transmission timing information indicating that these control codes 1 to 5 are transmitted from the transmission unit 36 with a code interval G1 is associated with the control codes 1 to 5.

　次に、図５を参照して、本実施形態に係る表示システムにおける伝送情報の伝送方法の一例について説明する。図５は、本実施形態に係る表示システムにおける伝送情報の伝送方法の一例を示すフローチャートである。
　ここで、ディスプレイ１の受信部３２は、リモコン送信機１０からリモコンコードの受信を拒否する状態である。この受信部３２は、計時部３１からの信号に基づき、直前のリモコンコードの受信から受信待ち時間を経過したか否かを判断する（ステップＳＴ１）。
　ここで、計時部３１は、直前のリモコンコードの受信から計時する時間が受信待ち時間を経過した場合、受信待ち時間が経過したことを示す信号を受信部３２に出力する。これにより、受信部３２は、リモコン送信機１０からのリモコンコードを受信可能な状態に遷移する（ステップＳＴ１－Ｙｅｓ）。 Next, an example of a transmission information transmission method in the display system according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing an example of a transmission method of transmission information in the display system according to the present embodiment.
Here, the receiving unit 32 of the display 1 is in a state of refusing reception of the remote control code from the remote control transmitter 10. Based on the signal from the time measuring unit 31, the receiving unit 32 determines whether or not a reception waiting time has elapsed since the reception of the immediately preceding remote control code (step ST1).
Here, the time measuring unit 31 outputs a signal indicating that the reception waiting time has elapsed to the receiving unit 32 when the reception waiting time has elapsed since the reception of the immediately preceding remote control code. Thereby, the receiving unit 32 transitions to a state in which the remote control code from the remote control transmitter 10 can be received (step ST1-Yes).
　次いで、リモコン送信機１０がリモコンコードをディスプレイ１に送信した場合、受信部３２は、このリモコンコードを受信し（ステップＳＴ２）、コード処理部３３に出力する。
　このコード処理部３３のコード判断部３３１は、例えば、入力するリモコンコードの内容を示すリモコン情報がリモコン情報「ａ」であることを判断し、判断結果であるリモコン情報「ａ」をコード生成部３３２におよび制御部３６に出力する。このリモコン情報「ａ」は、例えば、ディスプレイに含まれる表示部の電源をＯＮ／ＯＦＦすることを指示する制御情報である。 Next, when the remote control transmitter 10 transmits a remote control code to the display 1, the receiving unit 32 receives this remote control code (step ST2) and outputs it to the code processing unit 33.
The code determination unit 331 of the code processing unit 33 determines, for example, that the remote control information indicating the content of the remote control code to be input is the remote control information “a”, and the remote control information “a” as the determination result is used as the code generation unit. To 332 and to the control unit 36. The remote control information “a” is, for example, control information that instructs to turn on / off the power of the display unit included in the display.
　そして、コード生成部３３２は、このリモコン情報「ａ」を示す制御コード１～５を生成して、制御コード１～５がコード間隔Ｇ１をあけて順次送信部３６から送信されることを示す送信タイミング情報を制御コード１～５に対応づけた伝送コード１００を送信部３６に出力する。送信部３６は、入力する伝送コード１００に基づき、制御コード１～５を、コード間隔Ｇ１をあけてディスプレイ２に送信する（ステップＳＴ４）。
　また、判断結果であるリモコン情報「ａ」が入力された制御部３６は、このリモコン情報「ａ」に基づき、ディスプレイ１の表示部３５の電源をＯＮする（ステップＳＴ５）。 Then, the code generation unit 332 generates control codes 1 to 5 indicating the remote control information “a”, and indicates that the control codes 1 to 5 are sequentially transmitted from the transmission unit 36 with a code interval G1. The transmission code 100 in which the timing information is associated with the control codes 1 to 5 is output to the transmission unit 36. Based on the input transmission code 100, the transmission unit 36 transmits the control codes 1 to 5 to the display 2 with a code interval G1 (step ST4).
Further, the control unit 36 to which the remote control information “a” as the determination result is input turns on the power of the display unit 35 of the display 1 based on the remote control information “a” (step ST5).
　一方、ディスプレイ２の受信部５２は、ディスプレイ１から送信される伝送コード１００を受信し、コード処理部５３に出力する。この受信部５２は、伝送コード１００に含まれる制御コード１～５を、順次受信する（ステップＳＴ６）。
　ここで、計時部５１は、受信部５２が伝送コード１００に含まれる制御コード１～５を受信する間隔を計時し、制御コード１～５を受信する際のそれぞれの間隔を示す情報をコード判断部５３２に出力する。 On the other hand, the receiving unit 52 of the display 2 receives the transmission code 100 transmitted from the display 1 and outputs it to the code processing unit 53. The receiving unit 52 sequentially receives the control codes 1 to 5 included in the transmission code 100 (step ST6).
Here, the timer 51 measures the interval at which the receiver 52 receives the control codes 1 to 5 included in the transmission code 100, and determines the information indicating the intervals when receiving the control codes 1 to 5 by code determination. To the unit 532.
　このコード判断部５３１は、この制御コード１～５を受信する際のそれぞれの間隔を示す情報に基づき、予め決められたコード受信間隔Ｇ２以内で、直前に受信した制御コードに連続して受信する制御コードを、同一の伝送コードに含まれる制御コードと判断する。ここで、制御コード１～５を受信する際のそれぞれの間隔がコード受信間隔Ｇ２以内であった場合、コード判断部５３２は、制御コード１～５を同一の伝送コード１００に含まれる制御コードであると判断する。
　そして、コード判断部５３１は、この伝送コード１００に含まれる複数の制御コード１～５に基づき、各制御コード１～５が示すリモコン情報を得る。ここで、制御コード１～３のリモコン情報が「ａ」、制御コード４、５のリモコン情報が「ｍｉｓｓ（不明）」であるとする（ケース１参照）。コード判断部５３１は、このリモコン情報に基づき、同じ内容を示すリモコン情報の数が最も多いリモコン情報は、リモコン情報「ａ」であると判断する（ステップＳＴ７）。そして、コード判断部５３１は、判断結果であるリモコン情報「ａ」を制御部５４およびコード生成部５３２に出力する。 The code determination unit 531 continuously receives the control code received immediately before within the predetermined code reception interval G2, based on the information indicating the intervals when receiving the control codes 1 to 5. The control code is determined as a control code included in the same transmission code. Here, when the respective intervals when receiving the control codes 1 to 5 are within the code reception interval G2, the code determining unit 532 uses the control codes included in the same transmission code 100 as the control codes 1 to 5. Judge that there is.
Based on the plurality of control codes 1 to 5 included in the transmission code 100, the code determining unit 531 obtains remote control information indicated by the control codes 1 to 5. Here, it is assumed that the remote control information of the control codes 1 to 3 is “a” and the remote control information of the control codes 4 and 5 is “miss” (see case 1). Based on this remote control information, code determination unit 531 determines that the remote control information having the largest number of remote control information indicating the same content is remote control information “a” (step ST7). Then, the code determination unit 531 outputs remote control information “a” as a determination result to the control unit 54 and the code generation unit 532.
　そして、コード生成部５３２は、コード判断部５３１から入力される判断結果に基づき、伝送コード２００を作成する。つまり、コード生成部５３２は、判断結果であるリモコン情報「ａ」を含む制御コード１～５を生成し、コード間隔Ｇ１をあけて送信部５６から送信されることを示す送信タイミング情報を制御コード１～５に対応づけた伝送コード２００を送信部５６に出力する。そして、送信部５６は、伝送コード２００に基づき、制御コード１～５を、コード間隔Ｇ１をあけてディスプレイ３に送信する（ステップＳＴ９）。
　また、判断結果であるリモコン情報「ａ」が入力された制御部５６は、このリモコン情報「ａ」に基づき、ディスプレイ２の表示部５５の電源をＯＮする（ステップＳＴ１０）。 Then, the code generation unit 532 creates the transmission code 200 based on the determination result input from the code determination unit 531. That is, the code generation unit 532 generates the control codes 1 to 5 including the remote control information “a” as the determination result, and transmits the transmission timing information indicating that the code is transmitted from the transmission unit 56 with the code interval G1. The transmission code 200 associated with 1 to 5 is output to the transmission unit 56. Based on the transmission code 200, the transmission unit 56 transmits the control codes 1 to 5 to the display 3 with a code interval G1 (step ST9).
Further, the control unit 56 to which the remote control information “a” as the determination result is input turns on the power of the display unit 55 of the display 2 based on the remote control information “a” (step ST10).
　上述の通り、本実施形態に係るディスプレイ１は、受信したリモコンコードに基づき、同一のリモコン情報を示す複数の制御コード１～５を生成し、この制御コード１～５を連続してディスプレイ２に送信する。このディスプレイ２は、受信した制御コード１～５に基づき、この制御コード１～５がそれぞれ示すリモコン情報を得て、これら複数のリモコン情報のうち、同じ内容を示すリモコン情報の数が最も多いリモコン情報を、受信した制御コード１～５が示すリモコン情報であると判断する。そして、ディスプレイ２は、判断結果に基づき表示部５５を制御するとともに、判断結果であるリモコン情報を示す複数の制御コード１～５を生成し、この制御コード１～５を連続してディスプレイ３に送信する。
　このように直列的に連続して接続されているディスプレイ１～９のそれぞれにおいて、受信した複数の制御コード１～５の示すリモコン情報に基づき、多数決で制御コード１～５が示すリモコン情報を判断する。
　これにより、ディスプレイ１～９の伝送時において外乱により伝送コードの情報の欠落が発生した場合であっても、この欠落による誤りを次のディスプレイで発見し、修正することができる。よって、複数のディスプレイ１～９が直列的に接続されているシステムにおいて、途中で伝送コードの情報の欠落があった場合であっても、最後のディスプレイ９でリモコン情報に基づく制御を実現することができる。 As described above, the display 1 according to the present embodiment generates a plurality of control codes 1 to 5 indicating the same remote control information on the basis of the received remote control code, and the control codes 1 to 5 are continuously displayed on the display 2. Send. The display 2 obtains remote control information indicated by each of the control codes 1 to 5 based on the received control codes 1 to 5, and the remote controller having the largest number of remote control information indicating the same content among the plurality of remote control information. The information is determined to be remote control information indicated by the received control codes 1 to 5. The display 2 controls the display unit 55 based on the determination result, and generates a plurality of control codes 1 to 5 indicating the remote control information as the determination result, and the control codes 1 to 5 are continuously displayed on the display 3. Send.
In each of the displays 1 to 9 connected in series in this way, the remote control information indicated by the control codes 1 to 5 is determined by majority decision based on the received remote control information indicated by the plurality of control codes 1 to 5. To do.
As a result, even if transmission code information is lost due to disturbance during transmission of the displays 1 to 9, an error due to this loss can be found on the next display and corrected. Therefore, in a system in which a plurality of displays 1 to 9 are connected in series, control based on remote control information can be realized on the last display 9 even if transmission code information is missing on the way. Can do.
　また、上述の構成により、ディスプレイ１～９が、リモコン送信機１０からのリモコン情報に基づき、同一のリモコン情報の受信を繰り返すことで表示部３５の機能の状態のＯＮとＯＦＦを切り替えるトグル動作を行う場合、ディスプレイ１～９における動作の乱れの発生を防止することができる。
　本実施形態によらない場合を例に以下説明する。ディスプレイ１´がリモコン送信機１０´からリモコン情報「ａ」（ディスプレイの電源をＯＮ／ＯＦＦさせる制御信号）を受信した場合、途中のディスプレイにおいて受信ミスが発生すると、それ以降のディスプレイに対してリモコン情報「ａ」が伝送されない。これにより、リモコン情報「ａ」を受信したディスプレイでは電源がＯＮされるももの、受信ミスが発生したディスプレイ以降のディスプレイにおいては電源がＯＦＦのままである。これに続けて、ディスプレイ１´がリモコン送信機１０´からリモコン情報「ａ」を受信すると、現時点において電源がＯＮされているディスプレイは電源がＯＦＦされ、電源がＯＦＦされているディスプレイは電源がＯＮされる。従って、複数のディスプレイが連動して動作することができず、表示システムがうまく作動しない問題がある。
　本実施形態に係る表示システムは、上記構成により、上記問題を解決することができる。
　なお、このような問題は、リモコン送信機１０から受信するリモコンコードに従って制御されるディスプレイにおいては想定されない問題である。リモコン送信機１０からのリモコンコードの送受信が失敗した場合、再度、リモコン送信機１０からリモコンコードを送信すればよいからである。一方、上述のような表示システムでは、このようなリモコンコードを伝送する際のディスプレイ間における伝送ミスに対する補償が、そもそも従来想定されていなかったために上記問題が生じた。 Further, with the above-described configuration, the display 1 to 9 performs a toggle operation for switching ON / OFF of the function state of the display unit 35 by repeatedly receiving the same remote control information based on the remote control information from the remote control transmitter 10. When performed, it is possible to prevent the disturbance of the operation of the displays 1 to 9.
A case not according to the present embodiment will be described below as an example. When the display 1 ′ receives remote control information “a” (control signal for turning on / off the display) from the remote control transmitter 10 ′, if a reception error occurs in the display on the way, the remote control is performed for the subsequent displays. Information “a” is not transmitted. As a result, the display receiving the remote control information “a” is turned on, but the display after the display where the reception error has occurred remains off. Subsequently, when the display 1 ′ receives the remote control information “a” from the remote control transmitter 10 ′, the display that is currently turned on is turned off, and the display that is turned off is turned on. Is done. Therefore, there is a problem that a plurality of displays cannot operate in conjunction with each other and the display system does not work well.
The display system according to the present embodiment can solve the above problem by the above configuration.
Such a problem is not expected in a display controlled according to a remote control code received from the remote control transmitter 10. This is because if the remote control code transmission / reception from the remote control transmitter 10 fails, the remote control code may be transmitted from the remote control transmitter 10 again. On the other hand, in the display system as described above, the above-mentioned problem has occurred because compensation for transmission errors between displays when transmitting such a remote control code has not been assumed.
　ここで、以下の３つの問題が発生した場合について、本実施形態に係る表示システムの解決手段についてそれぞれ説明する。
　１つ目の問題として、例えば、リモコン送信機１０の操作部１２が短い間隔で連続して押下された場合、先に送信されたリモコンコードに続けて送信される次のリモコンコードに含まれる情報に欠落が生じる場合がある。
　上述の通り、本実施形態に係る表示システムでは、ディスプレイ１の受信部３２が、計時部３１から受信待ち時間が経過したことを示す信号を受信したか否かを判断し、受信待ち時間が経過したことを判断した場合、リモコン送信機１０から送信されるリモコンコードを受信する。これにより、先に送信されたリモコンコードを受信してから、次に送信されたリモコンコードを受信するまでの間隔が、受信待ち時間に達していない場合、次に送信されたリモコンコードの受信を拒否することができる。
　よって、上記１つ目の問題を解決し、情報の欠落が生じているおそれのある連続操作による次のリモコンコードの受信を回避することができる。 Here, the solutions of the display system according to the present embodiment will be described in the case where the following three problems occur.
As a first problem, for example, when the operation unit 12 of the remote control transmitter 10 is continuously pressed at a short interval, information included in the next remote control code transmitted after the previously transmitted remote control code. May be missing.
As described above, in the display system according to the present embodiment, the reception unit 32 of the display 1 determines whether or not the signal indicating that the reception waiting time has elapsed from the time measuring unit 31 and the reception waiting time has elapsed. If it is determined that the remote control code is transmitted, the remote control code transmitted from the remote control transmitter 10 is received. As a result, if the interval between receiving the previously transmitted remote control code and receiving the next transmitted remote control code has not reached the reception waiting time, receive the next transmitted remote control code. You can refuse.
Therefore, the first problem described above can be solved, and reception of the next remote control code by a continuous operation that may cause a loss of information can be avoided.
　２つ目の問題として、例えば、ディスプレイ１～９間の伝送中に外乱の影響を受けて、伝送データの情報が欠落する場合がある。
　上述の通り、本実施形態に係る表示システムでは、（１）直列的に接続されているディスプレイ１～９のそれぞれにおいて、受信した伝送コードに基づきリモコン情報を判断し、（２）判断されたリモコン情報を示す複数の制御コード１～５の連続して送信する。また、（３）送信部３６、５６が、予め決められているコード間隔Ｇ１をあけて制御コード１～５を送信側のディスプレイに送信し、（４）受信側のディスプレイが、コード受信間隔Ｇ２以内で受信する複数の制御コード１～５を同一の伝送コードに含まれる制御コードとして判断し、この制御コード１～５に基づき、多数決で、リモコン情報を判断する。
　これにより、上記２つ目の問題を解決し、ディスプレイ１～９の伝送時において外乱により伝送コードの情報の欠落が発生した場合であっても、この欠落による誤りを次のディスプレイで発見し、修正することができる。 As a second problem, for example, transmission data information may be lost due to the influence of disturbance during transmission between the displays 1 to 9.
As described above, in the display system according to the present embodiment, (1) the remote control information is determined based on the received transmission code in each of the displays 1 to 9 connected in series, and (2) the determined remote control A plurality of control codes 1 to 5 indicating information are continuously transmitted. Further, (3) the transmission units 36 and 56 transmit the control codes 1 to 5 to the transmission side display with a predetermined code interval G1, and (4) the reception side display displays the code reception interval G2. A plurality of control codes 1 to 5 received within 5 are determined as control codes included in the same transmission code, and remote control information is determined by majority decision based on the control codes 1 to 5.
As a result, the second problem is solved, and even if transmission code information is lost due to disturbance during transmission of displays 1 to 9, an error due to this loss is found on the next display, It can be corrected.
　３つ目の問題として、直列的に接続されているディスプレイ１～９のそれぞれにおいて、途中の一台で伝送コードの情報の欠落があった場合、ディスプレイ１～９を統括的に制御することができず、表示システムのうまく動作しなくなる。
　これは、１つ目の問題と２つ目の問題を解決する手段を両方用いることにより、解決することができる。つまり、複数のディスプレイ１～９が直列的に接続されているシステムにおいて、途中で伝送コードの情報の欠落があった場合であっても、最後のディスプレイ９でリモコン情報に基づく制御を実現することができる。 The third problem is that, in the case of each of the displays 1 to 9 connected in series, if there is a lack of transmission code information in the middle, the displays 1 to 9 can be controlled in an integrated manner. The display system does not work well.
This can be solved by using both means for solving the first problem and the second problem. That is, in a system in which a plurality of displays 1 to 9 are connected in series, control based on remote control information can be realized on the last display 9 even when transmission code information is missing on the way. Can do.
　なお、本実施形態に係る表示システムにおいて、ディスプレイ１～９は、ディスプレイ１が受信したリモコン送信機１０からのリモコンコードを直列的に伝送する例をあげて説明したが、本発明はリモコン送信機１０からのリモコンコードの伝送に限られない。例えば、複数のディスプレイや電子機器が直列的に接続されているシステムに適用可能である。

　さらに、送信部３６、５６が、データ処理部３３、５３から入力される複数の制御コード１～５を、予め決められているコード間隔Ｇ１をあけて、順次送信するものであってもよい。 In the display system according to the present embodiment, the displays 1 to 9 have been described with reference to an example in which the remote control code received from the remote control transmitter 10 received by the display 1 is serially transmitted. The transmission of the remote control code from 10 is not limited. For example, the present invention can be applied to a system in which a plurality of displays and electronic devices are connected in series.
Further, the code interval G1 of the plurality of control codes 1 to 5 on the display 1 on the transmission side and the code reception interval G2 when determined as control codes included in the same transmission code on the display 2 on the reception side are the same. Preferably there is. Note that the code reception interval G2 may be lengthened by this amount in consideration of the case where the transmission speed is reduced.
Further, the transmission units 36 and 56 may sequentially transmit a plurality of control codes 1 to 5 input from the data processing units 33 and 53 with a predetermined code interval G1.
