  Furthermore, according to the notification broadcast system according to the present invention, the notification broadcast receiver is provided with a reproducing means for reproducing the audio data, so that the group setting can be easily confirmed.

  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. Connected to the control unit 4 are a display 9, a printer 10, a keyboard 11, and the like for setting and inputting broadcast signals. The control unit 4 transmits an audio signal from the microphone 13 or the BGM source 33 to the notification broadcast transmission unit 12, and the audio signal is FM modulated by the notification broadcast transmission unit 12. 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, 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 type information including the audio information broadcast by the speaker of the notification broadcast receiver 16, the type of the notification broadcast, and the terminal information that is the target of the notification broadcast, and broadcast start / end Control information such as 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. The address designation includes all terminal designation for broadcasting all the participating terminals, group designation divided into blocks such as service areas and apartments, and individual designation for individually designating the joining terminals.

  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. . A memory 39 for storing various information is connected to the microcomputer 17.

  The memory 39 stores an individual address unique to each notification broadcast receiver 16, a group address corresponding to the group to which the own broadcast receiver belongs, and control information demodulated by the demodulator 22. Further, the memory 39 also stores data for setting a group address. This will be described in detail later.

  The notification broadcast receiver 16 has an audio amplifier 24 that amplifies audio information and a speaker 25 as an output means of the audio information demodulated by the demodulator 22, and the volume from the speaker 25 is set in front of the audio amplifier 24. A volume adjustment unit 28 for adjustment is provided. Further, the notification broadcast receiver 16 has an audio memory 31 for storing audio information of the received notification broadcast, and a recording unit 30 for storing the notification broadcast in the audio memory 31. The recording means 30 performs a recording process in which the audio information of the announcement broadcast output from the demodulator 22 is converted into recorded data and stored in the audio memory 31.

  The announcement broadcast from the center device 3 is transmitted to all the subscriber terminals. Then, the microcomputer 17 of the notification broadcast receiver 16 determines that its own terminal is a broadcast target when the terminal address specified in the control information of the notification broadcast matches the individual address or group address stored in the memory 39. The voice information output command signal is output to the output means, and the recording operation command signal is output to the recording means 30. Here, the control information demodulated by the demodulator 22 and stored in the memory 39 retains the correspondence with the audio information in the audio memory 31 and is used for reproduction, recording and erasure of the announcement broadcast.

  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. Furthermore, a notification lamp for notifying the recording state of the notification broadcast in the audio memory 31 is connected to the microcomputer 17. 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.

  Next, group setting for performing group broadcasting will be described. The group address is set by transmitting group setting data from the notification broadcast transmission unit 12 to each notification broadcast receiver 16. The group setting data is configured in the same format as the notification broadcast, and the type of data can be set to either the notification broadcast or the group setting by the control information. That is, the notification broadcast receiver 16 performs the above-described notification broadcast processing when the received data is notification broadcast, and performs group setting processing when the received data is group setting data.

  The control information of the group setting data is set by operating the keyboard 11 and is composed of a group address to be registered and an individual address of the notification broadcast receiver 16 belonging to the group. In addition, voice data representing the group, such as a group name, is input from a microphone or the like, and transmitted together with control information as voice information of group setting data. The microcomputer 17 of the notification broadcast receiver 16 associates the address of the group with the audio data when the individual address indicating the own device is specified in the control information of the group setting data demodulated by the demodulator 22. 39 is stored.

  The audio data stored in the memory 39 is used for checking the group setting. The microcomputer 17 reproduces the audio data stored in the memory 39 from the speaker 25 when the above-described reproduction switch 38 is pressed for a long time. Since the audio data is a group name or the like, the group set in the own device can be easily confirmed by reproducing the audio data. Further, instead of using the playback switch 38 also as a group confirmation function, a dedicated switch for playing back audio data may be newly provided.

  The microcomputer 17 is connected to a voice input means 40 such as a microphone and a voice recognition means 41. The voice input means 40 inputs a group number by voice, and the voice recognition means 41 recognizes the input voice and outputs a group address. In the memory 39, all the group addresses of the entire system and the corresponding audio data are stored in advance. The group address and audio data of the entire system may be stored and installed in advance in each notification broadcast receiver 16, or the group address and audio data set by the center device 3 may be set for each notification broadcast after the system starts operating. It may be downloaded to the receiver 16.

  When the group address obtained by the voice recognition unit 41 matches any of the group addresses stored in the memory 39, the microcomputer 17 stores the group address and corresponding voice data in the memory 39. Thereby, the group setting can be performed in each notification broadcast receiver 16. As a result, when it is determined by the above-described setting confirmation that the group setting data has not been set correctly due to reception of the group setting data, the group can be easily reset for each terminal. Even when a group is set directly in the notification broadcast receiver 16 as described above, it is easy to confirm the success or failure of the group setting by reproducing the audio data stored corresponding to the set group address.

  In this embodiment, each notification broadcast receiver 16 transmits a group address and corresponding audio data as a set to be transmitted and stored. However, the present invention is not limited to this. After all the group addresses and corresponding audio data are transmitted and stored, only the group address not including audio information may be transmitted and set for each notification broadcast receiver. In this case, the correspondence between the group address set to be transmitted by specifying the individual address and the audio data stored in advance is performed in the notification broadcast receiver, so that the group setting can be confirmed by the operation of the receiver.

  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.

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.
