DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information receiving apparatus for receiving character information transmitted from an external information transmitting apparatus by using radio waves of teletext broadcasting.

[0002]

2. Description of the Related Art Conventionally, in text multiplex broadcasting using FM radio waves or the like, information transmitted from an information transmitting apparatus is defined as one screen composed of a fixed format (for example, three lines of 15 characters per line). A plurality of pages constitute one program, and the programs include traffic information, weather information, program information, and the like.

Some of the above-mentioned receiving apparatuses have a function of storing received information and displaying the stored information when the receiving state deteriorates and reception becomes impossible. .

[0004]

However, in the above-mentioned conventional receiver having a function of displaying stored information, old information is continuously displayed unless the stored contents are updated. In the case of a type of program whose content is arbitrarily updated at any time, such as information, there is a problem that the displayed content may be different from the current situation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide an information receiving apparatus which can easily determine whether or not stored information is the latest content when displayed.

[0006]

As shown in FIG. 11, the invention of claim 1 receives and displays character information transmitted from an external information transmitting device 3 using a radio wave of a text multiplex broadcast. In the information receiving apparatus 2, receiving means 50 for receiving the transmitted information, display means 51 for displaying the received information, and storage means 5 for storing the received information
2 and the information of the reception date and time is added to the received information,
A storage control means 53 for storing the information in the storage means 52, a display control means 54 for displaying the information added with the date and time information on the display means 51, and the date and time of the display having passed a predetermined time or more from the reception date and time. It is characterized in that a notifying means 55 for notifying that time is provided.

According to a second aspect of the present invention, in the first aspect, an update frequency detecting means 56 for detecting an update frequency of the information stored in the storage means 52 is provided, and the notifying means 55 updates the displayed information. When the frequency is lower than a predetermined value, the fact is notified.

[0008]

According to the information receiving apparatus 2 of the present invention, the reception date and time information is added to the reception information stored in the storage means 52 by the storage control means 53, and the display control means 54 displays the display means 51. When the display date and time of the information displayed on the device has passed a predetermined time or more since the reception date and time,
When the display information is old, the notification means 55 notifies the fact.

As described above, the information that has been received for a predetermined time or more is notified to the user,
There is an effect that it can be easily determined whether the display content is the latest one.

[0010] According to the information receiving apparatus 2 of the present invention, when the update frequency of the stored information detected by the update frequency detecting means 56 is displayed below the predetermined value, the notifying means 55 informs the user of the fact. Will be notified.

As described above, the stored information that is not updated at a predetermined frequency is notified to the user, so that it is possible to more easily determine whether or not the display content is the latest one. is there.
