  FIG. 5 is a flowchart showing notification broadcast processing in the notification broadcast receiver. As shown in this figure, the microcomputer 17 first determines whether or not its own terminal is designated as a broadcast target in the received notification broadcast (RS1). If it is designated, whether or not the notification broadcast can be recorded is determined from the recordability data included in the control information of the notification broadcast (RS2). When the recording permission / inhibition data indicates that recording is permitted, it is determined whether or not the voice memory 31 is empty (RS3). If the voice memory 31 is empty, a control signal is sent to the output means and the recording means 30. Output and broadcast the audio information through the speaker 25 and record the audio information in the audio memory 31 (RS4). If there is no space, the broadcast information is output and the audio information is overwritten and recorded in the audio memory 31 (RS5). ). When the recording permission / prohibition data in RS2 indicates that recording is prohibited, only the broadcast output is performed (RS6), and the sound memory 31 is not recorded.

  That is, the microcomputer 17 broadcasts the received audio information and records or overwrites it in the audio memory 31 when the recording availability data included in the control information of the announcement broadcast indicates that recording is permitted, and the recording permission data prohibits recording. In the case shown, only the audio information is broadcasted and not recorded in the audio memory 31. Then, the microcomputer 17 erases the recorded sound information of the notification broadcast when the period set by the retention period data has elapsed.

  Also, in the operation of RS5, the type data included in the control information of the notification broadcast is compared, and if a notification broadcast having a lower importance than the new notification broadcast is recorded, the notification broadcast is deleted and a new one is recorded. The notification broadcast may be recorded, and the new announcement broadcast may not be recorded unless the announcement broadcast having a lower importance than the new announcement broadcast is recorded in the audio memory 31. As a result, even if the recording permission / inhibition data indicates that recording is permitted, it is possible to prevent the more important announcement broadcast already recorded in the audio memory 31 from being deleted.

  The microcomputer 17 is connected to an audio switching unit 36 that switches the output of the notification broadcast. The sound switching unit 36 is controlled by the microcomputer 17 and can switch between the notification broadcast output received by the demodulation unit 22 and the reproduction output of the notification broadcast stored in the sound memory 31.

 The microcomputer 17 is connected to a notification lamp for notifying the recording state of the notification broadcast in the audio memory 31. The notification lamp includes an emergency notification lamp 35 for emergency notification broadcasting and a general notification lamp 34 for general notification broadcasting. The microcomputer 17 is connected to a reproduction switch 38 for reproducing and outputting the sound information of the notification broadcast stored in the sound memory 31.

  The general notification lamp 34 or the emergency notification lamp 35 is turned on during recording of the notification broadcast, and is switched to a blinking state when the recording of the notification broadcast is completed. When the playback switch 38 for playing back the recorded notification broadcast is pressed, the light is turned off. Therefore, since the general notification lamp 34 or the emergency notification lamp 35 keeps blinking unless the received recording of the notification broadcast is confirmed by the operation of the playback switch 38, even when the terminal user is in the absence of the notification broadcast, You can easily know that there was an announcement broadcast.

  When the reproduction switch 38 for reproducing the recorded announcement broadcast is pressed, the microcomputer 17 as the reproduction means selects the announcement broadcasts stored in the audio memory 31 in the descending order of importance and reproduces them from the speaker 25. That is, the terminal user can listen to important emergency notification broadcasts and the like, which is convenient when it is not possible to take a long time to confirm unconfirmed notification broadcasts.

  As mentioned above, although embodiment of this invention was described, application of this invention is not restricted to these embodiment, It can apply variously within the range of the technical idea. For example, in the notification broadcast transmission process, first, broadcast start data is transmitted so that the notification broadcast receiver 16 can receive and output audio information, and the microphone 13 and the BGM source 33 directly perform the notification broadcast.
