Description

  The present invention relates to a mobile radio terminal device such as a mobile phone.

  As is well known, mobile phones have a function of receiving one-segment broadcasting (for example, see Patent Document 1). One-segment broadcasting has the advantage of not incurring a reception fee, but requires some operation to receive.

  Recently, apart from normal one-segment broadcasting performed by television stations, area-limited one-segment broadcasting that is broadcast only in specific areas such as large stores and public facilities has been performed. According to this broadcast, it is possible to provide information according to the needs of the viewer by making use of the characteristics of the broadcast area.

  However, for area-limited one-segment broadcasting, the broadcast channel is not always preset in the mobile radio terminal device. Unlike normal one-segment broadcasting, program information is not broadcast through a predetermined channel. For this reason, in order to view the area-limited one-segment broadcast, the user is required to perform a more complicated operation than to receive the normal one-segment broadcast, and there is a problem that convenience is low.
