  However, even with a receiver having a recording / playback function, the number of broadcasts that can be recorded is limited. For example, if there are a maximum of three broadcasts, when there are more broadcasts, the older ones are overwritten and recorded. As mentioned above, there are several types of announcement broadcasts, such as emergency broadcast / emergency group announcement broadcast, general broadcast / general group announcement broadcast, in descending order of importance. For example, even when an emergency announcement broadcast has already been recorded. If the maximum number of recorded broadcasts is exceeded, a new general notification broadcast with low importance will be received, and the emergency notification broadcast with high importance will be deleted in order to record it. Also, in order to record a general group announcement broadcast, it may happen that a more important general announcement broadcast must be deleted.

  The present invention has been made in view of the above problems, and provides a notification broadcast system that can prevent a notification broadcast with a high importance level from being deleted in order to record a notification broadcast with a low importance level. Objective.

In order to solve the above-described problems, a notification broadcasting system according to the present invention includes a notification device configured by connecting a center device having a notification broadcast transmission function and a notification broadcast receiver for receiving notification broadcasts from the center device. In the broadcasting system,
The center device includes a notification broadcast transmission unit that adds type data indicating the importance of the notification broadcast to the notification broadcast and transmits the data to the notification broadcast receiver.

Since it can confirm from broadcast, the convenience of a user can be improved.

  Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a notification broadcasting system in the present embodiment. First, the system configuration in this embodiment will be described. Reference numeral 1 denotes a transmission line as a signal line. In this embodiment, a coaxial cable of a CATV system is used. For this reason, a head end 2 is provided on the center side, and a television signal is transmitted from the head end 2 to a terminal. Is transmitting to the side. A transmission signal amplifier 29 is appropriately provided on the transmission line 1 in order to amplify the transmission signal. A center device 3 is provided on the center side, which is the head end 2 side, and a plurality of notification broadcast receivers 16 and 16 are connected to the terminal side of the transmission line 1 via branch terminals of the branching device 15.

  The center device 3 includes a control unit 4 that performs data processing and data transmission control, and a notification broadcast transmission unit 12 that transmits a notification broadcast to each notification broadcast receiver 16. The control unit 4 is connected to a display 9, a printer 10, a keyboard 11, and the like for inputting broadcast signal settings. Audio signals from the microphone 13 and the BGM source 33 are transmitted to the notification broadcast transmission unit 12, and are FM-modulated. An output from the notification broadcast transmission unit 12 is given to the transmission line 1 via the head end 2. Here, the control unit 4 can also transmit a broadcast signal from an audio device such as a tape recorder in addition to an audio signal from the microphone 13 or the BGM source 33. Alternatively, the character data input from the keyboard 11 and displayed on the display 9 can be encoded and transmitted as a broadcast signal. Furthermore, image data based on video input through the display 9 can be appropriately encoded and transmitted as a broadcast signal.

  The notification broadcast transmitted from the control unit 4 includes audio data broadcast by the speaker 25 of the notification broadcast receiver 16, type data including the type of notification broadcast and terminal information to be broadcast, and broadcast start / Control information such as end data is included. At this time, the transmission start or broadcast end time of the notification broadcast is read from the calendar circuit 37 and transmitted as the first or last sound of the sound information of the notification broadcast. The broadcast time may be sent as data instead of voice. The calendar circuit 37 may be provided on the notification broadcast receiver 16 side.

  The control information such as type data is set by operating the keyboard 11, and first, it is set whether the notification broadcast to be transmitted is an emergency notification broadcast or a general notification broadcast. Next, the address of the terminal device that is the target of the announcement broadcast is specified. There are two types of address designation: designation of all terminals for broadcasting to all participating terminals, and group designation that is divided into blocks such as service areas and apartments. In the case of group designation, a terminal address to be broadcast is designated by designating a block number with the keyboard 11. Or, conversely, the center device 3 side may designate and transmit only the block number, and it may be set to determine whether or not its own terminal is designated in the block transmitted on the notification broadcast receiver 16 side. .

  In other words, the announcement broadcast is an emergency broadcast that performs an emergency announcement broadcast to all subscriber terminals, a general broadcast that performs a general announcement broadcast to all subscriber terminals, and an emergency group that performs an emergency announcement broadcast to subscriber terminals divided into groups. Broadcasting is classified into general group broadcasting in which general announcement broadcasting is performed for subscriber terminals divided into blocks in groups. The emergency notification broadcast is more important than the general announcement broadcast, and the broadcast is more important than the group broadcast.

  The control unit 4 is also connected to a general telephone network 50, and at a specified time by registering the broadcast date / time, notification contents, broadcast group, etc. in advance from a telephone 51 such as a general home phone or a mobile phone. Announcement broadcasting can be performed automatically.

  Next, the notification broadcast receiver 16 provided at the terminal of the transmission line 1 will be described. FIG. 2 shows a block diagram of the notification broadcast receiver 16. As shown in this figure, the notification broadcast receiver 16 is provided with a demodulator 22 for receiving and demodulating the notification broadcast transmitted from the center apparatus 3, and a microcomputer 17 for controlling based on the control information included in the demodulated notification broadcast. . The output unit of the audio information demodulated by the demodulator 22 includes an audio amplifier 24 that amplifies the audio information and a speaker 25, and a volume for adjusting the volume from the speaker 25 in the previous stage of the audio amplifier 24. An adjustment unit 28 is provided.

  Further, the notification broadcast receiver 16 is provided with an audio memory 31 that stores audio information of the received notification broadcast, and a recording unit 30 that stores the notification broadcast in the audio memory 31. When the demodulator 22 receives the broadcast start data included in the control information from the center device 3, the recording unit 30 receives a recording operation command signal from the microcomputer 17. Then, a recording process for converting the sound information of the announcement broadcast output from the demodulator 22 into sound data and storing it in the sound memory 31 is performed.

  The audio memory 31 is divided into a plurality of memory areas, and includes an emergency broadcast memory 31a, a general broadcast memory 31b, and a general group memory 31c. When the announcement broadcast from the center device 3 is emergency broadcast and emergency group broadcast, the audio information of the announcement broadcast is stored in the emergency broadcast memory 31a, and in the case of general broadcast, the general broadcast memory 31b stores the general group. In the case of broadcasting, it is stored in the general group broadcast memory 31c. That is, the audio memory 31 is classified according to the importance level of the announcement broadcast. Note that the control information demodulated by the demodulator 22 is stored in a memory 39 provided in the microcomputer 17, the correspondence with the audio information in the audio memory 31 is maintained, and is used for reproducing, recording, and erasing notification broadcasts. . FIG. 3 shows a flowchart of the recording process of the received notification broadcast.

  As shown in FIG. 3, when the demodulator 22 receives the notification broadcast from the center device 3, the microcomputer 17 identifies the type of the notification broadcast from the type data added thereto (S1), and corresponds to this type data. It is determined whether or not there is a free memory area (S2). If there is a free space in the memory area corresponding to the type data, a control signal is output to the recording means 30, and a notification broadcast is recorded in the memory area corresponding to the type data (S3). Overwrite recording is performed in the memory area corresponding to the type data (S4).

  Since the audio memory 31 is divided into different memory areas for each type of notification broadcast, the notification broadcast can be recorded and overwritten in each memory area for each importance level. That is, even if it is a new notification broadcast, since a low-importance notification broadcast is recorded, it is possible to prevent the already-recorded high-importance notification broadcast from being deleted.

  In this embodiment, the audio memory 31 is divided into different memory areas for each type of notification broadcast. For example, the audio memory 31 is divided into two memory areas for emergency notification broadcast and other notification broadcasts. It is possible to divide and store only the emergency notification broadcast separately from other notification broadcasts. Conversely, for example, a large number of group notification broadcast memory areas may be provided for each group.

  Here, regarding the capacity of each memory area, for example, if the emergency broadcast memory 31a is made larger than the general broadcast memory 31b or the general group broadcast memory 31c, it is advantageous that a large number of important notification broadcasts can be recorded.

  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 data 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.

  Next, a second embodiment will be described. In the present embodiment, the recording process for the notification broadcast is different from that of the first embodiment. FIG. 4 shows a flowchart of the notification broadcast recording process in the present embodiment.

  Similarly to the first embodiment, when the demodulator 22 receives the notification broadcast from the center device 3, the microcomputer 17 identifies the type of the notification broadcast from the type data added thereto (S1), and corresponds to this type data. It is determined whether or not there is a free memory area (S2). If there is a free space in the memory area corresponding to the type data, recording is performed in the memory area corresponding to the type data (S3). If there is no free space in the memory area corresponding to the type data, it is determined whether there is a free space in the memory area corresponding to the broadcast type lower than the memory area (S4). If there is an empty space in the lower memory area, the announcement broadcast is recorded in this lower memory area (S5). If there is no empty space in the lower memory area, the memory area corresponding to the received announcement broadcast is overwritten. Recording is performed (S6).

  Here, in the operation of S6, if there is a lower memory area, it is determined whether or not there is a vacancy in the lower memory area. If there is a vacancy, the announcement broadcast is recorded. That is, when there is no space in the memory area corresponding to the type data, it is determined whether there is space in order up to the lowest memory area, and when there is no space in all the lower memory areas, the memory corresponding to the type data You will be recording over the area.

  As described above, in this embodiment, when there is no free space in the memory area corresponding to the type data, and there is a free space in the lower priority memory area than the received notification broadcast, this lower memory area The high-order broadcast received was recorded. Therefore, a large number of highly important announcement broadcasts can be recorded in the audio memory 31 with a limited number of recording broadcasts, and each memory area can be used effectively.

  In the present embodiment, the upper broadcast is recorded when there is an empty memory area corresponding to the lower broadcast. However, even if there is no empty lower memory area, the memory area corresponding to the type data is recorded. When is full, overwriting recording may be performed in a lower memory area. Thereby, it is possible to record more announcement broadcasts with high importance.

  Furthermore, in the state where emergency notification broadcasts are recorded in all memory areas, overwriting recording is only performed when emergency notification broadcasts are received, and overwriting recording is not performed even if notification broadcasts other than emergency notification broadcasts are received, It is possible to more surely prevent the important notification broadcast from being erased by the notification broadcast having a low importance.

  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. In the present embodiment, the audio memory 31 is divided into memory areas. However, a plurality of independent audio memories 31 are provided, and the received notification broadcast is recorded in each audio memory 31 for each type of notification broadcast. May be.

It is a block diagram which shows the structure of the notification broadcasting system in this embodiment. It is a block diagram which shows the structure of a notification broadcast receiver. It is a flowchart which shows the recording process of notification broadcasting. It is a flowchart which shows the recording process of the notification broadcast in 2nd Embodiment.
