要約
(EN)
A broadcast channel modification detection device receives a broadcast wave containing channel modification information including modification date and time of a physical channel of a broadcast wave and physical channels before and after the modification. According to the channel modification information, the broadcast channel modification detection device searches and detects channel modification plan information including the modification date and time concerning the physical channel to be modified in the television reception device and the physical channels before and after the modification. Next, when the modification date and time in the channel modification plan information precedes the current date and time according to the detected channel modification plan information, a broadcast wave is received by the physical channel after the modification in the channel modification plan information so as to judge whether actual reception is enabled.

L'invention concerne un dispositif de détection de modification de canal de radiodiffusion qui reçoit une onde de radiodiffusion contenant des informations de modification de canal qui comprennent la date et l'heure de modification d'un canal physique d'une onde de radiodiffusion et de canaux physiques avant et après la modification. En fonction des informations de modification de canal, le dispositif de détection de modification de canal de radiodiffusion recherche et détecte des informations de plan de modification de canal comprenant la date et l'heure de modification concernant le canal physique à modifier dans le dispositif de réception de télévision et les canaux physiques avant et après la modification. Ensuite, lorsque la date et l'heure de modification dans les informations de plan de modification de canal précèdent la date et l'heure courantes en fonction des informations de plan de modification de canal détectées, une onde de radiodiffusion est reçue par le canal physique après la modification dans les informations de plan de modification de canal afin d'évaluer si une réception réelle est autorisée.

放送チャンネル変更検出装置は、放送波の物理チャンネルの変更日時と変更前後の物理チャンネルとを含むチャンネル変更情報を含む放送波を受信し、上記チャンネル変更情報に基づいて、テレビジョン受信装置において変更すべき物理チャンネルに関する変更日時と変更前後の物理チャンネルとを含むチャンネル変更予定情報を検索して検出する。次いで、検出されたチャンネル変更予定情報に基づいて、上記チャンネル変更予定情報内の変更日時が現在日時よりも以前であるときに、上記チャンネル変更予定情報内の変更後の物理チャンネルで放送波を受信して実際に受信できるか否かを判断する。
