Description

  The present invention relates to a receiver for a notification broadcasting system for performing notification broadcasting.

  Notification broadcasting systems for performing various types of notification broadcasting from a center to a plurality of dwelling units are widespread. This notification broadcasting system is generally configured by connecting a center device arranged on the center side and a receiver installed in each dwelling unit via a transmission line such as CATV. Then, when performing general broadcasts such as holding local events or emergency broadcasts in the event of a fire or earthquake, the center device transmits a notification broadcast signal via a transmission line, and the receiver receives the notification broadcast signal. Then, the announcement broadcast is output by voice through a speaker (see, for example, Patent Document 1).

  In this announcement broadcasting system, in consideration of the possibility that the user cannot listen to the broadcast for reasons such as absence when the announcement broadcast is performed, a recording / playback function for recording and reproducing the announcement broadcast a predetermined number of times Is provided in the receiver. In this case, when the announcement broadcast is performed, the announcement broadcast is automatically recorded by the recording / reproducing function of the receiver, and when the reproduction instruction is received by the user's operation, the recorded announcement broadcast is reproduced (for example, Patent Document 2).

Japanese Patent Laid-Open No. 9-8753 JP 2006-261958 A

  In the conventional notification broadcasting system, after recording the notification broadcast up to the upper limit of the predetermined number of times, when recording a new notification broadcast, the recording memory space of the most recently recorded notification broadcast is new. I was recording over the announcement broadcast. In this way, when the deletion order is determined based solely on the recording order of the announcement broadcast, the importance of the announcement broadcast is ignored, and even the announcement broadcast with high importance is deleted first. Such an unfavorable situation may occur.

  In addition, when the recorded announcement broadcast is reproduced, the announcement broadcast is reproduced in the new order based on the recording order. In this way, when the playback order is determined based solely on the recording order of the announcement broadcast, the importance level of the announcement broadcast is ignored, and an unfavorable situation such as a high-importance announcement broadcast is not easily reproduced. Can happen.

  The present invention has been made in view of the above, and when recording and playing a notification broadcast by a receiver of the notification broadcast system, the priority order is determined in consideration of the type and reproduction history of the notification broadcast.

(Processing-Notification broadcast processing)
Next, notification broadcast processing in the notification broadcast system 1 configured as described above will be described. First, the notification broadcast process in the center apparatus 10 will be described. The operator on the center side inputs arbitrary audio information using the microphone 13 and the BGM source 14 of the center apparatus 10 in FIG. At this time, the operator uses the operation unit 11 to specify whether the notification broadcast is a general broadcast or an emergency broadcast, and when the broadcast is a general broadcast, inputs the scheduled broadcast date and time. General broadcast is a method that does not require urgency, for example, local event information or regular broadcast, and emergency broadcast is a broadcast that requires urgency, for example, disaster information. Further, the operator uses the operation unit 11 to specify the receiver 20 that is the reception destination.

  Upon receiving these various inputs, the control unit 18 of the center apparatus 10 determines whether the notification broadcast is a general broadcast or an emergency broadcast based on the content specified by the operator, and determines that the broadcast is an emergency broadcast. Obtains the unique address of the receiver 20 designated by the operator from the memory, and generates a broadcast command including the unique address and information for identifying the emergency broadcast. The broadcast command and the audio information input by the operator are modulated on a carrier having a predetermined frequency to generate a notification broadcast signal. The notification broadcast signal is transmitted to the head end 41 via the transmission unit 17. Send.

  On the other hand, when it is determined that the broadcast is a general broadcast, the control unit 18 acquires the unique address of the receiver 20 designated by the operator from the memory, and includes the unique address and information for specifying the broadcast. Generate broadcast commands. Then, the broadcast command and the audio information input by the operator are recorded in the memory 15. Thereafter, the control unit 18 monitors whether or not the scheduled broadcast date and time designated by the operator has arrived based on the date and time information from the date and time circuit 16, and when the scheduled broadcast date and time has arrived, broadcasts from the memory 15. Get command and audio information. Then, the control unit 18 generates a notification broadcast signal by modulating the broadcast command and the audio information on a carrier having a predetermined frequency, and transmits the notification broadcast signal to the head end 41 via the transmission unit 17. . Thus, the notification broadcast process in the center device 10 is completed.

  Next, notification broadcast processing in the receiver 20 will be described. A flowchart of this notification broadcast processing is shown in FIG. The head end 41 that has received the notification broadcast signal transmitted from the center device 10 by the above-described processing transmits the notification broadcast signal via the transmission line 42. The notification broadcast signal transmitted in this way is amplified or distributed by the amplifier 43, the distribution amplifier 44, or the distributor 46, and then arrives at the protector 48 of each dwelling unit and passes through the protector 48. A signal is input to the receiver 20.

  In the receiver 20, the input notification broadcast signal is demodulated by the demodulator 21 (step SA- 1), the broadcast command is input to the controller 30, and the audio information is adjusted in volume via the audio switching unit 22. Are output to the unit 24 and the audio recording unit 23. The control unit 30 determines whether or not the address included in the broadcast command matches its own address recorded in advance in the memory 29 (step SA-2), and when it does not match (step SA-2). , No), the notification broadcast process is terminated, and if they match (step SA-2, Yes), a control signal is output to the audio switching unit 22 so that audio information is output. The voice switching unit 22 that has received this control signal outputs the demodulated voice information to the volume adjusting unit 24. The audio information is output from the speaker 26 after volume adjustment by the volume adjustment unit 24 and amplification by the amplifier 25.

  At this time, the control unit 30 determines whether or not the broadcast command indicates that the notification broadcast is an emergency notification broadcast (step SA-3), and if it is an emergency notification broadcast (step SA- 3, Yes), the emergency broadcast indicator lamp 28b is turned on or blinked, and the sound volume information is output at a predetermined high volume for emergency notification broadcasting by controlling the volume adjusting unit 24 (step SA-4). On the other hand, when the broadcast command indicates that the notice broadcast is a general notice broadcast (step SA-3, No), the control unit 30 turns on or blinks the general broadcast indicator lamp 28c and sets the volume. By controlling the adjusting unit 24, the audio information is output at the volume set by the volume switch (step SA-5).

  After the output control is performed as described above, the recording process for recording the voice information is executed by the recording control unit 30a (step SA-6), so that the voice information is recorded by the voice recording unit 23. Thereafter, when the user gives a reproduction instruction via the notification reproduction switch 27b (step SA-7, Yes), the audio information recorded in the audio recording unit 23 is controlled by the reproduction control unit 30b. 22 is output to the volume adjusting unit 24 via the speaker 22 and output from the speaker 26 (step SA-8).

  In addition, the recording process in step SA-6 is performed in the same way when a voice message is recorded, other than when a notification broadcast is received. That is, when the user inputs a voice message to the microphone 32 while pressing the voice memo switch 27d, this voice message is recorded as voice information by the voice recording unit 23, and the user gives a playback instruction via the notification playback switch. And output from the speaker 26.

(Processing-Recording process)
Next, the recording process in step SA-6 will be described in detail. 4 and 5 are flowcharts of the recording process. The recording control unit 30a determines whether or not there is an unrecorded area in the audio recording unit 23 (step SB-1). If the unrecorded area exists (step SB-1, Yes), the recording is already performed. The voice information is recorded in the unrecorded area without overwriting the recorded voice information (step SB-11), and the recording process is completed.

  On the other hand, if there is no unrecorded area (step SB-1, No), the recording control unit 30a needs to delete one of the audio information already recorded in the audio recording unit 23 to create an unrecorded area. Therefore, the audio information to be erased is determined. In this erasure target determination processing, the priority order of erasure is determined in the order of reproduced audio information, voice memo audio information, general announcement broadcast audio information, and emergency announcement broadcast audio information.

  Specifically, the recording control unit 30a determines whether there is reproduced audio information among the audio information already recorded in the audio recording unit 23 (step SB-2), and has been reproduced. When there is one or more audio information (step SB-2, Yes), the reproduced audio information is set as the deletion candidate audio information (step SB-12). For example, when the audio information is reproduced in a reproduction process described later, the determination as to whether or not the reproduced audio information is present corresponds to the number of reproduction times information (corresponding to the reproduction history information in the claims). ) Is set, and the content of the reproduction count information is determined in step SB-2. When the reproduced audio information is set as the deletion candidate audio information, it is not necessary to select other audio information as the deletion candidate, and the process proceeds to step SB-6 described later.

  On the other hand, when there is no reproduced voice information (step SB-2, No), the recording control unit 30a determines whether or not there is voice memo voice information (step SB-3). If there are two or more (step SB-3, Yes), the voice information of the voice memo is set as the deletion candidate voice information (step SB-13). Whether or not there is voice information of the voice memo is determined by, for example, determining the type information added to the voice information in the recording process in step SB-11 described later (in this way, the determination is based on the type information). (This is the same in the determination of audio information of general announcement broadcasting in step SB-4 described later). When the voice information of the voice memo is set as the erasure candidate voice information, it is not necessary to select other voice information as the erasure candidate. Therefore, the process proceeds to step SB-6 described later.

  Next, when there is no voice information of the voice memo (step SB-3, No), the recording control unit 30a determines whether there is voice information of the general announcement broadcast (step SB-4), and the voice of the general announcement broadcast. If there is one or more information (step SB-4, Yes), the audio information of the general announcement broadcast is set as the erasure candidate audio information (step SB-14). If the audio information of the general announcement broadcast is set as the deletion candidate audio information, it is not necessary to select other audio information as the deletion candidate, and the process proceeds to step SB-6 described later.

  Next, when there is no audio information of the general announcement broadcast (step SB-4, No), the recording control unit 30a performs the audio information already recorded in the audio recording unit 23 at that time (in this case, the audio of the emergency broadcast) All of the information is set as deletion candidate voice information (step SB-5).

  Thereafter, in step SB-6, the recording control unit 30a determines whether or not there are a plurality of pieces of audio information that have been selected as erasure candidates so far (step SB-6). 6, No), the only speech information selected as the erasure candidate is set as the final erasure candidate (step SB-7), and when there are a plurality of erasure candidates (step SB-6, Yes), the plurality of erasure candidates Among them, the audio information with the oldest timing recorded in the audio recording unit 23 is set as a final erasure candidate (step SB-8). The recording timing is determined by determining the recording timing information added to the audio information in the recording process in step SB-11 described later.

  Then, the unrecorded area is generated in the sound recording unit 23 by deleting the sound information set as the final deletion candidate in this way (step SB-9). In this case, the recording control unit 30a records erasure history information for specifying the type of the erased audio information in the memory 29 (step SB-10).

  Next, the recording control unit 30a records the newly acquired voice information in the generated unrecorded area (step SB-11). At this time, the recording control unit 30 a adds the type information indicating the type of the recorded audio information to the audio information and records it in the audio recording unit 23. In addition, the recording control unit 30a acquires date and time information at that time by a known method, adds the date and time information to the audio information as recording timing information, and records it in the audio recording unit 23. This completes the recording process.

  FIG. 6 illustrates the state of the recording area of the audio recording unit 23. In the example of FIG. 6, the audio information with the recording area numbers = “2” and “3” is selected as erasure candidates in step SB-12 of FIG. 4, and the recording area number == in step SB-7 of FIG. The audio information “3” is selected as the final erasure candidate, and new audio information is recorded in this recording area.

  Further, after such a recording process is performed, the control unit 30 monitors the erasure history information recorded in the memory 29 in step SB-10 at a predetermined interval, and when the erasure history information is recorded. Notifies the user that there is erased audio information. The notification form is arbitrary. For example, the receiver 20 shown in FIG. 2 is provided with an indicator lamp for erasure notification (corresponding to the erasure notification means in the claims), and this indicator lamp is lit or blinked. . A user who sees the indicator lamp can easily grasp the fact that once recorded voice information is automatically deleted. In this case, notification may be performed only when unreproduced audio information is erased. In this case, the user has recorded audio information that has not been heard yet. The fact that information is automatically deleted can be easily grasped. Alternatively, the notification may be performed only when the voice information of the voice memo that has not been reproduced is deleted (this is the same in the voice notification of the deletion history information in step SC-13 in FIG. 7 described later).

(Processing-Reproduction processing)
Next, the reproduction process in step SA-8 in FIG. 3 will be described in detail. FIG. 7 is a flowchart of the reproduction process. When the user gives a reproduction instruction via the notification reproduction switch 27b, the reproduction control unit 30b determines the priority order of reproduction of the audio information recorded in the audio recording unit 23. In this priority order determination process, unreproduced audio information is preferentially reproduced over reproduced audio information. Also, among each of the reproduced audio information and the unreproduced audio information, the priority order of reproduction is determined in the order of the audio information of the emergency announcement broadcast, the audio information of the general announcement broadcast, and the audio information of the voice memo.

  Specifically, the reproduction control unit 30b determines whether there is unreproduced audio information in the audio information recorded in the audio recording unit 23 (step SC-1), and unreproduced audio If there is information (step SC-1, Yes), steps SC-2 to SC-6 are performed for the unreproduced audio information. That is, the reproduction control unit 30b determines whether or not there is emergency notification broadcast audio information in unreproduced audio information (step SC-2), and there is one or more emergency notification broadcast audio information. (Step SC-2, Yes), the audio information of the emergency notification broadcast is set as the reproduction candidate audio information (step SC-3). For example, whether there is unreproduced audio information is determined by setting a reproduced flag in the audio information reproduced in step SC-14, which will be described later, and determining whether or not there is the reproduced flag in step SC-1. It is done by judging. Further, for example, whether or not there is audio information of emergency notification broadcast is determined based on the type information added to the audio information in step SB-11 of FIG. 5 (whether there is audio information of general notification broadcast or not). The same in the judgment).

  When there is not one or more emergency notification broadcast audio information (step SC-2, No), the reproduction control unit 30b determines whether or not general reproduction broadcast audio information is included in the unreproduced audio information ( Step SC-4) If there is one or more audio information of the general announcement broadcast (step SC-4, Yes), the audio information of the general announcement broadcast is set as the reproduction candidate audio information (step SC-5). ). When there is not one or more general announcement broadcast audio information (step SC-4, No), the reproduction control unit 30b uses the remaining unreproduced audio information (in this case, audio information of a voice memo) as reproduction candidate audio information. (Step SC-6).

  On the other hand, when it is determined in step SC-1 that there is no unreproduced audio information (step SC-1, Yes), the reproduction control unit 30b targets steps SC-2 to SC-6 for the reproduced audio information. The same processing is performed in steps SC-7 to SC-11, and reproduction candidate audio information is set. Then, the audio information having the smallest number of reproductions so far is set as the audio information of the reproduction candidate from the audio information set as the reproduction candidates so far (step SC-12). The determination of the number of times of reproduction is performed based on the information on the number of times of reproduction, for example, by setting the number of times of reproduction as audio information reproduced in step SC-15 described later.

  Thereafter, when there are a plurality of pieces of audio information that have been selected as reproduction candidates so far, the reproduction control unit 30b selects the audio information with the latest recorded timing in the audio recording unit 23 among the plurality of reproduction candidates. The final reproduction candidate is set (step SC-13). However, if there is only one piece of audio information selected as a reproduction candidate so far, the audio information is set as a final reproduction candidate. Then, the audio information set as the final reproduction candidate is reproduced through the speaker 26 (step SC-14). Further, before or after the reproduction of the final reproduction candidate, the reproduction control unit 30b acquires the erasure history information recorded in the memory 29 in step SB-10 in FIG. 5, and based on the erasure history information. The audio information for notifying the user of the deleted audio information may be output. For example, voice notification such as “Voice memo has been deleted” is performed by synthesizing voice data recorded in advance in the memory 29.

  When the reproduction is performed in this way, the reproduction control unit 30b adds the reproduction number information to the audio information that has been reproduced in the audio recording unit 23. That is, the initial value of the playback count information = “1” is set at the first playback, and the playback count information is incremented by 1 at the second playback and thereafter (step SC-15). This completes the playback process.

  For example, in the example of FIG. 6, the recording area numbers = “1”, “4” and “5” are selected as reproduction candidates in step SC-1 of FIG. 7, and the recording area numbers are selected in step SC-2. = "1" audio information is selected and output as the final reproduction candidate.

(Effect of embodiment)
As described above, according to the present embodiment, the priority of erasure of audio information recorded in the audio recording unit 23 is based on the type of audio information already recorded in the audio recording unit 23 or the reproduction history of the speaker 26. Since the order is determined, it is possible to delete information with low importance and leave information with high importance, and it is possible to perform overwriting recording of voice information that matches the convenience of the user. Further, since the reproduction order of the audio information by the speaker 26 is determined based on the type of the audio information already recorded in the audio recording unit 23 or the reproduction history by the speaker 26, the reproduction of the less important information is postponed. Therefore, it is possible to preferentially reproduce information with high importance, and it is possible to reproduce audio information that matches the convenience of the user.

  Further, since the audio information that has already been reproduced by the speaker 26, the audio information of the general announcement broadcast, and the audio information of the emergency announcement broadcast are preferentially deleted and overwritten and recorded, information that has not been reproduced and is highly urgent can be obtained. It can be left, and overwriting recording of voice information that matches the convenience of the user can be performed. Further, since the audio information of the emergency announcement broadcast, the audio information of the general announcement broadcast, and the audio information already reproduced by the speaker 26 are preferentially reproduced, information that has not yet been reproduced and is highly urgent is preferentially reproduced. Therefore, it is possible to reproduce audio information that matches the convenience of the user.

  In addition, the voice information of the voice memo by the microphone 32 is preferentially erased from the emergency broadcast, or the emergency broadcast is preferentially reproduced to record or reproduce the audio information that matches the convenience of the user. be able to.

  Further, since the priority order of erasure or playback is determined based on the timing at which the audio information is recorded in the audio recording unit 23, for example, the recorded timing is erased from the oldest or the recorded timing is new. Audio information that matches the convenience of the user can be recorded or reproduced, for example, in order.

  In addition, since the display unit for erasure notification and the speaker 26 that outputs information related to the audio information erased by the audio recording unit 23 are provided, even when the audio information is automatically erased, the fact of the erase is used. The user can be notified and the situation where the user is erased without noticing the presence of the voice information can be prevented.
