SUMMARY OF THE INVENTION A business broadcast system comprises:
As the broadcast scale becomes larger, it is necessary to prepare a program timer having a larger number of control output terminals, and connect input devices and output devices to a center unit (matrix) or a program timer. Moreover, if it is not clear which input device is connected to which input device and which output device is connected to which output device, it is not possible to create a broadcast program. If it is necessary to change the connection, it will lead to erroneous broadcasting unless the connection work is examined in detail, and in some cases, unless the input / output connection itself is changed, it will be impossible to cope.

[0006] In addition, even when one broadcast is performed, a contact opening / closing operation such as turning on / off an amplifier before and after the broadcast and turning on / off a power supply of a corresponding device such as a tape recorder during the broadcast program is performed during the broadcast program. In addition, there is a problem that it is necessary to describe each of them, and it is necessary to be skilled in the creation thereof, and it is difficult to cope with a sudden change in the broadcast program.

The present invention has been made in view of the above circumstances, and has as its object to provide a broadcast program creation method for a business broadcast system in which a broadcast program can be easily created and changed.

[0008]

An object of the present invention is to switch and connect a plurality of input devices respectively connected to a plurality of input contacts and a plurality of output devices respectively connected to a plurality of output contacts by a line control unit. In the broadcast program creating method of the business broadcast system for broadcasting an audio signal input from a predetermined input device from a predetermined output device, by managing connection information of each device, the input contact and the output contact It is possible to group related contact groups for each event included in a broadcast program, and by specifying an event in a broadcast program, the make / remake state of the grouped contact group corresponding to this event is automatically set. This can be achieved by describing in a formal manner.

[0009] Preferably, in the above, the business broadcasting system comprises: a program timer capable of outputting a series of make / remake information of input / output contacts based on the contents of a broadcast program in the form of serial data; A center unit that is connected to each of the terminals and has a plurality of output devices connected to each of the plurality of output terminals, receives the serial data, and controls connection between the input device and the output device based on make / remake information of a corresponding contact. (Matrix).

Each of the plurality of input devices has a different operation,
There are a type that reproduces the make-keeping period BGM of the control terminal, a type that starts a message at the rise of the control terminal, and a type that receives message broadcast control by serial control.
By retaining the classification and connection information of these connected devices, even in a system in which a plurality of devices are mixed, grouping of events and batch migration described below can be performed.

[0011] The present invention further preferably provides the above-mentioned,
When moving the event position in the broadcast program, the entire make / remake state of the group of related contacts corresponding to the event is moved collectively,
Priorities are assigned to the programs that make up a broadcast program.If multiple programs compete during the same time zone during automatic creation of a broadcast program, the program with the higher priority is placed on top of the program with the lower priority. Overwrite.

More preferably, in the above, when the execution of the higher priority program is switched from the lower priority program, the audio output method for starting the higher priority program is automatically corrected according to the type of the input device. At the time of execution switching from a program with a low priority to a program with a high priority, the output sound of the program with a low priority is automatically faded out before the required time before the execution switching,
When ending a program with a high priority and starting a program with a low priority, the program starts while automatically fading in the output sound of the program with a low priority.

[0013] For example, for each event of a chime in the morning and an event of a break start broadcast in the morning, related contact groups necessary for executing each event are grouped. Since the make / remake state is automatically developed in the broadcast program, the program can be easily created, the event can be easily moved, and a sudden program change can be handled. Further, even if a program conflict occurs, fade-in, fade-out, and the like are automatically set, so that a sense of incongruity does not occur during business broadcast.

Enter from. Thus, when the control unit 11a sends a command to that effect to the center unit 4 via the communication unit 11d, the center unit 4 transmits the monitor sound output from the semiconductor memory to the sound input terminal 21 (this terminal). Is also used as a monitor audio output terminal, as will be described later.)
Wrap back to The returned monitor sound is transmitted to the control unit 1
In response to a command from the remote control microphone 1a, the sound is input to the audio input / output switching unit 12f from the audio input / output terminal 13 of the remote control microphone 1a, sent from the audio input / output switching unit 12f to the monitor audio output control unit 12g, and output from the speaker 15.

The program timer 5 is configured to be able to perform control using a virtual communication contact function, while being able to follow a mixture of existing contact control devices and a program design technique. I have. That is, in the broadcast program according to the present embodiment, for example, the chime is activated by turning on the contact number # 1 at am 8:00, and the broadcast line is opened by turning on the contact # 2 and the contact # 3. In accordance with this program, the control unit 53b turns on the contact output number # 1 at am8: 00 and simultaneously turns on the communication contacts 102 and 103 at am8: 00 according to the program.

Is turned on, the power of the external sound source 2 is turned on and the BGM
Starts. The BGM is input to one of the audio input terminals 21 of the center unit 4 and, based on a signal sent from the program timer 5 to the center unit 4 via a communication cable, the BGM is output by the output device designated by the program timer 5. Output from

Since the CPU 24 of the center unit 4 needs to know whether the audio output from the external sound source 2 is actually input to the center unit 4, if the audio output is output from the external sound source 2, A busy signal indicating this is input from the external sound source 2 to the control input terminal 23a of the center unit 4, and the CPU 24 detects this. When the external contact terminal 5 of the program timer 5 is added, a dedicated expansion unit is connected to cope with it.

Each output of 3 is connected to an input section of the line control unit 25, and the output of the reproduction buffer 42 is output from the speaker 3. The output of the monitor reproduction buffer 43 is the remaining one input of the monitor system selector 33.

The external contact system has a contact control input section 45 connected to the control input terminal 23a and a contact control output section 46 connected to the control output terminal 23b.
24, the contact control input unit 45 transfers the signal received from the control input terminal 23a to the CPU 24,
The contact control output unit 46 that has received the command from the PU 24 controls the corresponding control output terminal 23b to turn on and off. The center unit 4 operates based on the concept of a virtual contact as described above, but also has an external contact system for coexistence with existing contact control devices.

In the center unit 4, the number of audio input terminals 21 functioning as virtual contacts, the number of control input terminals 22a and the number of control output terminals 23b, which are real contacts, are
By installing dedicated terminal boards, they can be expanded.

The CPU of the center unit 4 having the above configuration
24 receives a communication signal (broadcast program signal) from the program timer 5 captured from the communication terminal 22b, and refers to the above-described correspondence table in the memory 27a based on the ON / OFF signal of the virtual contact in the communication signal. The line selection switch group 31 (the function of this switch is to select the audio input side as a normal operation and send it to the A / D converter. If you want to monitor the broadcast destination on the input device side (remote control microphone), A signal selected as an output (a signal to the terminal 26a) is selected and returned to the corresponding audio input side.
The line of the line controller 25 is switched. Thus, the output audio signal of the corresponding input device (remote control microphone or external sound source) is converted into a digital signal by the corresponding A / D converter 30 through the line selection switch group 31, and the line control unit 25 outputs the digital signal. Is selected, converted into an analog signal by the D / A converter 32 on the selected output path, and output from the corresponding speaker 3.

Here, for example, when the content broadcast from the remote control microphone installed in the broadcast room is recorded and the broadcast is repeated after a predetermined time, a predetermined operation button of the remote control microphone is pressed. Thereby, the CPU of the center unit 4
24 receives a request signal fetched from the terminal 22a via the communication cable, closes the recording system selection switch 39, outputs a control command to the recording / reproduction control unit 40, and transmits an output signal of a remote control microphone installed in the broadcasting room to the line. A control signal is output to the line selection switch group 31 so as to be taken in from the selection switch group 31, and the line control unit 25 is controlled so as to select a speaker for outputting the sound.

The output signal of the remote control microphone installed in the broadcasting room is converted into a digital signal by the corresponding A / D converter 30, passes through the line control unit 25, and is converted to a digital signal by the corresponding D / A converter 3.
2 is output to the corresponding speaker in the same manner as described above, but the digital signal output from the A / D converter 30 is also input to the recording buffer 41 through the recording system selection switch 39. The recording / reproduction control unit 40 records the audio signal captured from the recording buffer 41 in the external storage device 36 or a memory device mounted in the card slot 37. A hard disk or the like is used as the external storage device 36. As the memory device, a PC memory card, a Compact Flash (registered trademark), or the like is used.

By recording in this way, the recorded content is:
It can be used for broadcasting as an internal sound source. Here, if the input of the remote control microphone in the broadcasting room or a person near another remote control microphone wants to listen to the recorded content, the user presses a predetermined operation button of the remote control microphone installation and transmits a request signal to the communication cable. The data is transmitted to the CPU 24 via

Upon receiving this request signal, the CPU 24 sends a control signal to the recording / reproducing control unit 40, and the monitor reproduction buffer 43
The recording signal is output through the
3 is input. The CPU 24 controls the monitor system selecting unit 33
The CPU 24 also outputs a selection command to the selection switch 34 to select the output of the monitor system selection unit 33. As a result, the recorded audio signal is input to the selection switch 32.
Is converted into an analog signal by the D / A converter 32, and then returned to the line selection switch group 31 to be sent to the remote control microphone requesting the recorded content.

The signal of the recorded content is supplied from terminal 21 to FIG.
Flows through a monitor audio selection unit 12c, a selection addition unit 12e, and a monitor audio output control unit 12d, and is output from a speaker 15 installed in a remote control microphone.

When the remote control microphone confirms the recorded content while recording the output sound of the remote control microphone as the built-in sound source in the center unit 4, the request signal is output to the CPU 24 via a communication cable. Upon receiving the request signal, the CPU 24 closes the recording system selection switch 39 to perform recording, and at the same time, outputs a selection command to the monitor system selection unit 33 and the selection switch 34 to cause the monitor system selection unit 33 to select a recording signal. . Thus, the recording can be monitored simultaneously with the recording.

When it is desired to confirm the sound actually output from any of the speakers 3 on a speaker provided with a remote control microphone such as a broadcasting room, a request signal to that effect is output to the CPU 24 via a communication cable. Upon receiving the request signal, the CPU 24 sets the monitor system selection unit 33 and the selection switch 3
4 and outputs a selection command to the monitor system selection unit 33 to select a signal returned as an input to the monitor system selection unit 33 from among the signals output from the line control unit 25. Return to switch group 31. This allows the remote control microphone to check the content actually being broadcast in the building in the broadcast room or the like.

As described above, in the business broadcasting system of the present embodiment, the input device and the output device are connected based on the concept of virtual communication contacts, and business broadcasting is performed from a desired input device to a desired broadcast area. Although the configuration is used to facilitate system connection, even if the number of contact points between the input device and the output device becomes enormous, a broadcast program can be easily created and changed. It is, for example, as shown in FIG.
When creating a program at the start of M8: 00, the program creator can perform the grouping “AM8: 00 Start”.

Then, the arithmetic means automatically manages the detailed broadcast program by referring to the association table data between the contacts from within the program of “8:00 pm”. For example, when the contact A is turned on, the contact B is turned on x minutes before the contact B and turned off y minutes before, and the contact B is turned on m seconds before the contact A is turned on. This is the contact grouping data for turning on the contact C. The arithmetic means refers to such table data, and the 7:54:55 amplifier is turned on 7:55:00 in the above example of “start of work” 7:55:00 The input terminal to which the tape recorder that records the radio exercise music is connected Connect to the rooftop speaker 7:55:00 Turn on the tape recorder 7:59:55 Turn off the tape recorder 7:59:55 Connect the input terminal to which the chime sound source is connected to all output terminals 8:00:00 Chime sound source 8:00:05 Connect the input terminal to which the CD player is connected and the speaker 8:00:05 Turn on the CD player 8: 00: 05: 00 Disconnect the output terminal and the input terminal 8: 00: 05: 00 Turn off the amplifier A series of contact opening / closing programs (broadcasting programs) are automatically checked to see if there are any unsuitable places, and contacts are automatically assigned according to song numbers and grouped. And keep it as data.

When the program for the morning opening chime created as described above is to be moved and changed at 10:00,
Conventionally, it is necessary to re-create each contact opening / closing program while adjusting with other programs around 10:00. However, in this embodiment, the broadcast programs can be automatically changed by assigning priorities to the individual programs in the group. For example, if there is a BGM broadcast program around 10 o'clock before the start program moves, the start chime-related program has a higher priority than BGM, so the start chime program is unconditionally moved, The opening chime program is overwritten on the BGM program.

When sound is output from the speaker, it may be better to change the manner of outputting the sound from the speaker depending on the type of the sound. For example, there is a method in which output sound from a digital sound source is immediately output from a speaker, and output sound from an analog sound source is output in a manner of fading in. Such an output method is
In order to set separately from the input / output device connection settings, when the broadcast program is moved as described above, the output method is also changed according to the type of input source (sound source) accompanying the switching of the input / output device before and after the movement. An arithmetic processing unit refers to a data table describing an output method corresponding to an input source, and automatically corrects the data table.

Similarly, it is not suitable for business broadcasts if the overwritten broadcast (BGM in the above example) is suddenly cut off, so that it is preferable to fade out the lower broadcast. Also in this case, the arithmetic processing unit
The broadcast program is automatically corrected with reference to a data table describing a method of fading out (corresponding to a time at which the fade-out starts) corresponding to the input source. In addition, it is preferable that the start of the original lower broadcast program (BGM in the above example) after the end of the program after the movement is faded in, and this is also automatically corrected by the arithmetic processing unit.

When the priorities of the broadcast programs before and after the movement are the same, the method of giving priority to the original program,
On the contrary, there is a method of giving priority to the program afterward, and it is preferable to be able to set which one is adopted. Alternatively, the program movement can be canceled by warning that the overlap has occurred.

The business broadcasting system as in the above-described embodiment is a multi-system broadcasting system, and a situation occurs in which a speaker line having a high output priority and a speaker line having a low output priority exist at the same time. While the setting of the priority of the speaker line having the higher priority is replaced by the movement of the program, the input source may not be switched due to the higher priority of the input source. For example, while outputting the sound of the sixth song in the CD to the speakers on the first, second, and third floors, it is desirable to lower the priority of the speaker on the second floor and output another sound. If the input source is the same CD
In the case of the first music, the music cannot be output because the sixth music is being output. If a broadcast program that causes such a situation is automatically created, there is a problem that the broadcast from the speakers on the second floor is actually interrupted. In order to avoid the occurrence of such a situation, it is desirable to adopt a configuration in which the association between the priority order and the connection of the input / output devices is integrally managed.

Therefore, for example, when an attempt is made to move an event program to AM 10:00,
Identify the highest priority broadcast program present during the 9:50 to 10:10 AM period (this identification is
It is easily obtained by taking the OR logic of the priority of each broadcast program during this time. ), Management can be facilitated by adopting a management method of comparing this priority with the priority of a broadcast program to be moved.

The above-described automatic program generation, modification, and change are performed, for example, when the storage medium storing the broadcast program describing the event “AM 8:00 start of business” is inserted into the card slot 54 of FIG.
May be developed into a detailed broadcast program by referring to the table data storing the grouping information of the contact group, but the display unit 5 provided in the program timer 5 may be used.
Since 3d has a small display area, it is not easy to check automatically generated and automatically changed programs. Therefore, in the present embodiment, the PC 6 connected to the center unit 4 is used to
A detailed broadcast program is automatically generated, corrected, and changed using a wide monitor screen of C6, and a warning is output when a broadcast conflict as described above occurs. Then, the result of automatic generation, modification, and change is transferred to the program timer 5 via the center unit 4 via a communication cable, or stored in a storage medium, and inserted into the card slot 54 of the program timer 5. I do.

In the above-described embodiment, the event "opening chime" has been described as an example. However, the present invention is not limited to this event. By grouping the related contact groups, it is possible to automatically generate, move, and correct broadcast programs corresponding to various situations.

According to the above-described embodiment, since programs are grouped for each event, there is an advantage that the work of changing the broadcast program is facilitated, and even an unskilled person can respond. At the actual business broadcast site, many program changes are required. For example, in business broadcasting such as a department store, since the broadcast contents and business hours are changed according to the season, it is necessary to change the broadcast program accordingly. In addition, the building manager often notices an inadequacy of the business broadcast program after listening to a specific business broadcast in the presence of the facility at the start of operation. In such a case, if the broadcast program cannot be changed without a skilled person, the business broadcast itself becomes impossible. However, by grouping related program groups as in the present embodiment, an unskilled person However, it becomes possible to easily and quickly respond to changes in the broadcast program.

[0060]

According to the present invention, the amount of items that need to be set in time is reduced, so that the creation of a broadcast program, that is, the setting of time in a business broadcast system is facilitated, and it is possible to eliminate program creation work errors. Furthermore,
The change of the broadcast program can be easily and quickly performed even by an unskilled person.
