Definitions

  • the electric field strength measurement unit 301 measures the received electric field strength of the broadcast signal received by each of the tuners 4a and 4b and the FM tuner 4c.
  • the reception quality measuring unit 302 measures the reception quality of the broadcast signal received by each of the tuners 4a and 4b and the FM tuner 4c.
  • the reception quality is a parameter that is an indicator of the reception quality of the received broadcast signal, and includes, for example, a bit error rate of a signal obtained by decoding a demodulated signal of the broadcast signal.
  • the timer 24 measures the time elapsed from the storage time in association with the identification information of the alternative candidate station every time the alignment value of the alternative candidate station is stored in the list of the alignment storage unit 21. Therefore, the link control unit 20 can confirm the elapsed time since the alignment value is stored in the list of the alignment storage unit 21 by referring to the time measurement information of the timer 24.
  • step ST11 If the DAB reception state has not deteriorated (step ST11; NO), the DAB-FM link processing is terminated.
  • the series of processes shown in FIG. 2 is executed when reception is switched to regular or another DAB broadcast.
  • step ST11; YES when the DAB reception state deteriorates (step ST11; YES), the link control unit 20 proceeds to the DAB-FM link process shown in step ST12.
  • the present invention is not limited to this.
  • the present invention can also be applied to a so-called DAB-DAB link that receives a DAB broadcasting a program having the same content when the DAB reception state deteriorates.
  • the present invention can be applied to services other than DAB such as HD (High Definition) radio.
  • radio broadcasting has been described so far, the present invention can also be applied to television broadcasting. That is, the present invention can be applied to any function that switches the reception target from the first broadcast that is received to the second broadcast that includes a program with the same content that has a different reception frequency from that of the first broadcast. .

Abstract

Selon la présente invention, une unité de commande de liaison (20) détermine s'il est nécessaire de mettre à jour une valeur d'alignement stockée dans une unité de stockage d'alignement (21) sur la base du temps écoulé et/ou du changement dans un état de réception de diffusion FM, après que la valeur d'alignement a été stockée dans l'unité de stockage d'alignement (21). Une unité de calcul de valeur d'alignement (22) met à jour la valeur d'alignement stockée dans l'unité de stockage d'alignement (21) lorsque la mise à jour est déterminée comme étant nécessaire. Une unité de commande vocale (300) règle, au moyen de la valeur d'alignement mise à jour, l'état de sortie des données vocales de diffusion FM lorsqu'une diffusion à recevoir est commutée d'une diffusion DAB à une diffusion FM.
