Description

【０００１】
【発明の属する技術分野】
この発明は、表示方法に関する。
【０００２】
【従来の技術】
ＦＭ放送においては、文字情報などの番組を音声の番組と一緒に放送する技術が実用化されている。このＦＭ文字多重放送は、日本の場合、ＤＡＲＣ方式と呼ばれ、文字情報などのデジタルデータが音声番組の信号に周波数多重化して放送されるものである。
【０００３】
そして、文字情報としては、ニュース、天気予報、交通情報、音声番組を補完する番組（例えば、音声番組が音楽であれば、その曲名、演奏者など）などがあり、さらに、ＧＰＳ情報、ＶＩＣＳ情報なども放送されている。
【０００４】
【発明が解決しようとする課題】
ところが、現行のＦＭ文字多重放送受信機においては、受信した文字情報を複数の機器で共有することができない。
【０００５】
したがって、ある受信機で受信した文字情報を複数の機器で表示したり、いくつかの文字番組を複数の機器に分散して表示したりすることができない。また、複数のＦＭ文字多重水平受信機で受信した複数の文字番組を１つの表示デバイスにまとめて表示することができない。
【０００６】
この発明は、これらの問題点を解決しようとするものである。
【０００７】
【課題を解決するための手段】
このため、この発明においては、
文字多重放送を受信する放送受信部と、
この放送受信部によって受信された上記文字多重放送を表示部に表示させる表示制御部と、
上記放送受信部によって受信された上記文字多重放送のデータを他の機器に送信するデータ送信部と
を有する文字多重放送データ送信機
とするものである。
したがって、ＦＭ文字多重放送受信機の受信した文字多重放送のデータを各機器が共有する。
【０００８】
【発明の実施の形態】
図１においては、２台のＦＭ文字多重放送受信機１０、２０と、１台のナビゲーション装置３０とを接続した場合を示す。
【０００９】
そして、受信機１０においては、ＦＭ文字多重放送の放送波信号が、アンテナ入力回路からＦＭ復調回路までを有するチューナ回路１１に供給されて音声番組のオーディオ信号（ステレオコンポジット信号あるいはモノラル信号）と、文字番組により変調されたＬＭＳＫ信号との多重化信号が取り出される。そして、この多重化信号がデコーダ回路１２に供給されて文字番組のデータがデコードおよびエラー訂正されて取り出され、このデータがシステム制御用のマイクロコンピュータ１３を通じてメモリ１４に格納されていく。
【００１０】
そして、キー１５を操作すると、メモリ１４に格納されたデータのうち、目的とする文字番組のデータが、マイクロコンピュータ１３によりメモリ１４から読み出され、この読み出されたデータがディスプレイコントローラ１６を通じて表示用のメモリ１７に書き込まれる。また、このとき、このメモリ１７に書き込まれたデータがディスプレイコントローラ１６により読み出されて表示信号が形成され、この表示信号が表示デバイス、例えばＬＣＤ１８に供給され、ＬＣＤ１８には、メモリ１７に書き込まれたデータに対応した文字、すなわち、目的とする文字番組が表示される。
【００１１】
さらに、この受信機１０はインターフェイス回路１９を有し、このインターフェイス回路１９がマイクロコンピュータ１３に接続されるとともに、外部のバスライン１００に接続される。
【００１２】
また、受信機２０も受信機１０と同様に構成されるもので、対応する回路には１０台に代わって２０台の参照符号を付けて説明は省略する。そして、この受信機２０のインターフェイス回路２９もバスライン１００に接続される。
【００１３】
さらに、ナビゲーション装置３０において、符号３１はそのナビゲーション装置本体である。このナビゲーション装置本体３１は、地図データの入ったＣＤ−ＲＯＭあるいはＤＶＤ−ＲＯＭ、走行位置および走行速度を検出するためのジャイロ装置、ＧＰＳ受信回路などを有する。
【００１４】
そして、このナビゲーション装置本体３１が、キー３５の操作にしたがってシステム制御用のマイクロコンピュータ３３により制御されて必要とするデータが取り出され、このデータがディスプレイコントローラ３６を通じて表示用のメモリ３７に書き込まれるとともに、コントローラ３６により読み出されて表示デバイス、例えばＬＣＤ３８に供給され、地図などのナビゲーション情報が表示される。また、このナビゲーション装置３０においても、マイクロコンピュータ３３が、インターフェイス回路３９を通じてバスライン１００に接続される。
【００１５】
なお、ＬＣＤ１８、２８、３８は、ドットの組み合わせにより各種の文字や図形などを表示するものとする。また、オーディオ信号系については、説明を省略する。
【００１６】
このような構成によれば、受信機１０の受信した文字番組のデータを、バスライン１００を通じて他の機器２０、３０に供給することができるとともに、受信機２０の受信した文字番組のデータを、バスライン１００を通じて機器１０、３０に供給することができる。あるいは、機器１０、３０は、バスライン１００を通じて受信機２０のメモリ２４のデータを得ることができ、機器２０、３０は、バスライン１００を通じて受信機１０のメモリ１４のデータを得ることができる。つまり、受信機１０、２０の受信した文字番組の情報をすべての機器１０、２０、３０で共有することができる。
【００１７】
なお、この場合、メモリ１４、２４にデータを格納したときのアドレス情報と、そのデータを示すインデックス画面のデータとを、それぞれの機器に送るようにすれば、各機器はインデックス画面を表示することができるとともに、そのインデックス画面に関連してアドレス情報を得ることができるので、これによりメモリ１４、２４のうち、本来のデータの格納されているアドレスを知ることができ、したがって、各機器はどの情報を表示するかを選択することができる。
【００１８】
したがって、例えば、図２に示すように、ＬＣＤ１８の上半分に受信機１０の受信した文字番組を表示し、下半分に受信機２０の受信した文字番組を表示することができる。あるいは、例えば、ＬＣＤ１８の上半分および下半分に番組情報および天気予報を表示し、ＬＣＤ２８の上半分および下半分にニュースおよび交通情報を表示することができる。そして、これらの場合には、ユーザは複数の情報を同時に得ることができる。
【００１９】
また、例えば、図３に示すように、異なる文字番組をスクロールにより順番に表示することもでき、この場合には、ユーザは探している情報を複数の番組の中から容易に選択することができる。
【００２０】
さらに、受信機１０により文字番組に含まれるＶＩＣＳ情報を受信し、受信機２０により文字番組に含まれる差分ＧＰＳ情報を受信し、これらの情報をナビゲーション装置３０に供給すれば、より精度の高いナビゲーション情報を表示することができる。
【００２１】
こうして、上述のシステムによれば、受信機１０、２０の受信した文字番組のデータをメモリ１４、２４に格納するとともに、バスライン１００を通じてメモリ１４、２４を他の機器からアクセスできるようにしているので、受信した文字番組のデータを各種の機器１０、２０、３０で自由に利用することができる。
【００２２】
したがって、システム内にＦＭ文字多重放送を受信できる受信機が１台でも接続されていれば、その受信機で受信したデータをシステム内で共有することができる。また、これにより、ＦＭ文字多重放送の受信機能のない機器でも、その表示デバイスに文字情報を表示することができる。あるいは、ナビゲーション装置にＦＭ文字多重放送の受信機能がなくても、ＶＩＣＳ情報や差分ＧＰＳ情報を利用することができる。
【００２３】
さらに、ニュース、天気予報などの複数の文字番組をそれぞれの表示デバイスに分散して表示することにより同時に表示することができる。また、逆に、１つの表示デバイスに複数の文字番組を表示することもできる。
【００２４】
【発明の効果】
この発明によれば、受信した文字番組のデータを各種の機器で自由に利用することができる。

[0004]
[Problems to be solved by the invention]
However, in the current FM character multiplex broadcast receiver, the received character information cannot be shared by a plurality of devices.
[0005]
Therefore, the character information received by a certain receiver cannot be displayed on a plurality of devices, and some character programs cannot be distributed and displayed on a plurality of devices. In addition, a plurality of character programs received by a plurality of FM character multiplexed horizontal receivers cannot be displayed together on one display device.
[0006]
The present invention is intended to solve these problems.
[0007]
[Means for Solving the Problems]
For this reason, in the present invention,

It is an Rubun character multiplex broadcasting data transmitter having a data transmission unit that transmits data over Kibun shaped multiplex broadcast received by the broadcast receiving unit to another device.
Therefore, each device shares the text multiplex broadcast data received by the FM text multiplex broadcast receiver.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a case where two FM teletext receivers 10 and 20 and one navigation device 30 are connected.
[0009]
In the receiver 10, a broadcast wave signal of FM text multiplex broadcasting is supplied to a tuner circuit 11 having an antenna input circuit to an FM demodulation circuit, and an audio signal (stereo composite signal or monaural signal) of an audio program, A multiplexed signal with the LMSK signal modulated by the character program is taken out. Then, this multiplexed signal is supplied to the decoder circuit 12 and the data of the character program is decoded and error-corrected and taken out, and this data is stored in the memory 14 through the microcomputer 13 for system control.
[0010]
When the key 15 is operated, the data of the target character program among the data stored in the memory 14 is read from the memory 14 by the microcomputer 13 and the read data is displayed through the display controller 16. Is written in the memory 17 for use. At this time, the data written in the memory 17 is read out by the display controller 16 to form a display signal. The display signal is supplied to a display device, for example, the LCD 18, and is written in the memory 17 in the LCD 18. The character corresponding to the data, that is, the target character program is displayed.
[0011]
Further, the receiver 10 has an interface circuit 19, which is connected to the microcomputer 13 and to the external bus line 100.
[0012]
The receiver 20 is also configured in the same manner as the receiver 10, and corresponding reference circuits are denoted by 20 reference numerals instead of 10 and description thereof is omitted. The interface circuit 29 of the receiver 20 is also connected to the bus line 100.
[0013]
Further, in the navigation device 30, reference numeral 31 denotes the navigation device body. The navigation device main body 31 includes a CD-ROM or DVD-ROM containing map data, a gyro device for detecting a traveling position and a traveling speed, a GPS receiving circuit, and the like.
[0014]
The navigation device main body 31 is controlled by the system control microcomputer 33 in accordance with the operation of the key 35, and necessary data is taken out. The data is written into the display memory 37 through the display controller 36. The information is read out by the controller 36 and supplied to a display device such as an LCD 38, where navigation information such as a map is displayed. Also in the navigation device 30, the microcomputer 33 is connected to the bus line 100 through the interface circuit 39.
[0015]
Note that the LCDs 18, 28, and 38 display various characters, graphics, and the like by combinations of dots. Further, description of the audio signal system is omitted.
[0016]
According to such a configuration, the character program data received by the receiver 10 can be supplied to the other devices 20 and 30 through the bus line 100, and the character program data received by the receiver 20 can be It can be supplied to the devices 10 and 30 through the bus line 100. Alternatively, the devices 10 and 30 can obtain data in the memory 24 of the receiver 20 through the bus line 100, and the devices 20 and 30 can obtain data in the memory 14 of the receiver 10 through the bus line 100. That is, the information on the character program received by the receivers 10 and 20 can be shared by all the devices 10, 20 and 30.
[0017]
In this case, if the address information when the data is stored in the memories 14 and 24 and the data of the index screen indicating the data are sent to each device, each device displays the index screen. Since the address information can be obtained in relation to the index screen, it is possible to know the address where the original data is stored in the memories 14 and 24. It is possible to select whether to display information.
[0018]
Therefore, for example, as shown in FIG. 2, the character program received by the receiver 10 can be displayed on the upper half of the LCD 18 and the character program received by the receiver 20 can be displayed on the lower half. Alternatively, for example, program information and weather forecasts can be displayed on the upper and lower halves of the LCD 18 and news and traffic information can be displayed on the upper and lower halves of the LCD 28. In these cases, the user can obtain a plurality of information simultaneously.
[0019]
Also, for example, as shown in FIG. 3, different character programs can be displayed in order by scrolling, and in this case, the user can easily select the information they are looking for from a plurality of programs. .
[0020]
Furthermore, if the receiver 10 receives the VICS information included in the character program, the receiver 20 receives the differential GPS information included in the character program, and supplies these information to the navigation device 30, navigation with higher accuracy is possible. Information can be displayed.
[0021]
Thus, according to the above-described system, the character program data received by the receivers 10 and 20 are stored in the memories 14 and 24, and the memories 14 and 24 can be accessed from other devices through the bus line 100. Therefore, the received text program data can be freely used by the various devices 10, 20, and 30.
[0022]
Therefore, if at least one receiver capable of receiving FM teletext broadcasting is connected in the system, the data received by the receiver can be shared in the system. In addition, this makes it possible to display character information on the display device even with a device that does not have an FM character multiplex broadcast reception function. Alternatively, even if the navigation device does not have an FM character multiplex broadcast reception function, VICS information and differential GPS information can be used.
[0023]
Furthermore, a plurality of character programs such as news and weather forecasts can be displayed simultaneously by being distributed and displayed on each display device. Conversely, a plurality of character programs can be displayed on one display device.
[0024]
