Abstract:
(EN) Provided is a modulation system whereby errors can be easily found. The modulation system 200A comprises: a first modulator 201 that, by generating a control signal and modulating an input signal in accordance with the generated control signal, controls the brightness of a first light source 211 emitting light in accordance with the modulated input signal and outputs the control signal; and a second modulator 202 that, by obtaining the control signal output by the first modulator 201 and modulating an input signal in accordance with the control signal, controls the brightness of a second light source 212 emitting light in accordance with the modulated input signal and outputs the control signal. The first modulator 201: generates, as a light ID signal, a control signal for sending a visible light signal by using the change in brightness of the first light source; and obtains a light information signal being a control signal output from the second modulator 202.
(FR) L'invention concerne un système de modulation au moyen duquel des erreurs peuvent être facilement trouvées. Le système de modulation 200A comprend : un premier modulateur 201 qui, par génération d'un signal de commande et modulation d'un signal d'entrée conformément au signal de commande généré, commande la luminosité d'une première source de lumière 211 émettant une lumière conformément au signal d'entrée modulé et délivre le signal de commande ; et un second modulateur 202 qui, par obtention du signal de commande délivré par le premier modulateur 201 et modulation d'un signal d'entrée conformément au signal de commande, commande la luminosité d'une seconde source de lumière 212 émettant une lumière conformément au signal d'entrée modulé et délivre le signal de commande. Le premier modulateur 201 : génère, sous la forme d'un signal d'identifiant (ID) de lumière, un signal de commande pour envoyer un signal de lumière visible par utilisation du changement de luminosité de la première source de lumière ; et obtient un signal d'informations de lumière qui est un signal de commande délivré à partir du second modulateur 202.
(JA) 異常を容易に見つけることができる変調システムを提供する。変調システム200Aは、制御信号を生成して、生成された制御信号に応じて入力信号を変調することによって、変調された入力信号にしたがって発光する第1の光源211の輝度を制御し、かつ、その制御信号を出力する第1の変調機201と、第1の変調機201から出力された制御信号を取得し、その制御信号に応じて入力信号を変調することによって、変調された入力信号にしたがって発光する第2の光源212の輝度を制御し、かつ、その制御信号を出力する第2の変調機202とを備え、第1の変調機201は、第1の光源の輝度変化によって可視光信号を送信するための制御信号を、光ID信号として生成し、第2の変調機202から出力される制御信号である光情報信号を取得する。
