BACKGROUND OF THE INVENTION
The present invention relates to a local broadcasting device, and more particularly to a device for monitoring the state of a matrix used in the broadcasting device.
[0002]
[Prior art]
Some local broadcasting apparatuses have a plurality of sound sources, a plurality of speakers, and a matrix. The matrix connects each sound source to a desired speaker in accordance with a control signal from the CPU. Which speaker is connected to which speaker is stored as a pattern in the memory for each sound source. When a certain sound source starts operating, the CPU reads a pattern corresponding to the operating sound source from the memory, and the CPU connects the operating sound source to each speaker specified by the pattern. To control. In this private broadcasting apparatus, each pattern is stored in a memory by a user using a display device and operation keys.
[0003]
[Problems to be solved by the invention]
It is desirable to be able to monitor which sound source is currently broadcasting to which speaker when this local broadcasting apparatus is actually operating. In particular, it is desirable to be able to perform such monitoring when the operating sound source changes over time.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, the invention according to claim 1 corresponds to each of the sound sources, a plurality of sound sources, a plurality of speakers, matrix means provided between each of the sound sources and each of the speakers, and A storage unit storing a plurality of patterns, and a pattern corresponding to the sound source activated each time any of the sound sources is activated is read from the storage unit, and based on the read pattern Control means for controlling the matrix means so as to connect a designated speaker and the energized sound source; and display means for displaying a control state that changes every time the control of the matrix means changes. is doing.
[0005]
According to the first aspect of the invention, when a certain sound source is energized, a pattern corresponding to the sound source is read from the storage means, and based on this pattern, the control means controls the matrix and is energized. The sound of the selected sound source is broadcast from a desired speaker. At this time, since how the matrix is controlled is displayed on the display means, it can be determined to which speaker the energized sound source is supplied. When the energized sound source is changed to another sound source, the display on the display means is similarly changed.
[0006]
According to a second aspect of the present invention, in the first aspect of the present invention, the storage means also stores the priority order of the patterns when the speakers designated by the patterns compete. The control means controls the matrix means based on a high priority pattern when the competition occurs.
[0007]
According to the second aspect of the present invention, in a state where the matrix is controlled by a certain pattern, the sound from another sound source is supplied to the speaker to which the sound from the certain sound source is supplied by this pattern. When a pattern is selected, i.e., when a pattern conflict occurs, the matrix means is controlled based on the higher priority pattern. For example, if the priority of the current pattern is higher, the current pattern is maintained. If the priority of the pattern specified later is higher, the matrix means is controlled according to the pattern specified later. If there is such a competition, whether or not the control state of the matrix has changed is also displayed on the display means.
[0008]
According to a third aspect of the present invention, in the second aspect of the present invention, when a speaker designated in the same priority pattern competes with the storage means, the previously performed broadcast is given priority, and this broadcast ends. After that, either a preemptive style for performing later broadcasting or a preemptive style for performing broadcasting based on a later pattern by interrupting the previously performed broadcast is set.
[0009]
According to the third aspect of the present invention, in the state where the matrix is controlled in accordance with a certain pattern, when the same priority pattern conflicts, the matrix is determined according to which pattern stored in the storage means has priority. Be controlled. In this way, even when patterns with the same priority order compete, it is possible to know in real time whether the control state of the matrix has changed.
[0010]
According to a fourth aspect of the present invention, in the private broadcasting apparatus according to the second aspect, when a part of speakers designated by each pattern competes with the storage means, a non-competing speaker having a low priority pattern is used. Either a lockout on state where the broadcast is interrupted or a lockout off state where the broadcast is continued is set for each pattern.
[0011]
According to the invention of claim 4, when a pattern having a higher priority than the current pattern is selected, the matrix means is controlled based on the pattern having a higher priority. Of the speakers specified in the current pattern, those that have been heard until now but can no longer appear appear. In this case, the processing of whether to make it inaudible or to maintain the current broadcast only for these speakers is stored in the storage means, and the matrix means is controlled according to this storage. This change in the control state of the matrix is also displayed on the display means.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, the local broadcasting apparatus 1 according to the embodiment of the present invention receives signals from a plurality of sound sources, for example, input devices 2. As these input devices 2, an audio file in which an announcement at the time of opening a store, an announcement at the time of closing a store is recorded, a tape recorder loaded with a tape storing music for BGM, a microphone for in-store broadcasting, etc. are used. The In FIG. 1, four input devices 2 are shown, but the number can be arbitrarily changed according to the demand in the facility that broadcasts on the premises.
[0013]
Of these input devices 2, the announcement at the time of opening the store, the announcement at the time of closing, and the BGM are automatically activated at a predetermined time by a program timer (not shown). Further, the in-store broadcasting microphone is operated by a user's operation when necessary. These input devices 2 output audio signals when activated, and generate control signals indicating that they are operating.
[0014]
The audio signal is amplified by the amplifier 6 in the input unit 4 of the local broadcasting device 1, converted into a digital audio signal by the A / D converter 8, and supplied to the matrix circuit 10. The control signal is supplied to matrix control means, for example, the CPU 14 via the input / output interface 12 in the input unit 4.
[0015]
The digital audio signal output from the matrix circuit 10 is converted into an analog audio signal by the D / A converter 18 of the output unit 16, amplified by the amplifier 20 of the output unit 16, and further an amplifier 22 outside the private broadcasting apparatus 1. And supplied to a plurality of speakers 24. Although four of these speakers 24 are shown in FIG. 1, the number thereof can be arbitrarily increased or decreased depending on the size of the building in which the local broadcasting apparatus is installed.
[0016]
The matrix circuit 10 has a plurality of input lines 26 corresponding to the respective input devices 2 and a plurality of output lines 28 corresponding to the respective speakers 24. A plurality of bus lines 30 are provided between the input lines 26 and the output lines 28. At the intersection of each input line 26 and each bus line 30, a switch, for example, a semiconductor switch, is provided for connecting or disconnecting each input line 26 and each bus line 30. Similarly, at the intersection of each output line 28 and each bus line 30, a switch, for example, a semiconductor switch, which connects or disconnects these lines is provided. The CPU 14 switches these switches.
[0017]
Therefore, the audio signal of any input device 2 can be supplied to the desired speaker 24 by appropriately selecting the semiconductor switch to be connected. For example, the audio signal of the input device 2 for in-store broadcasting is supplied to all the speakers 24, but the audio signal of another input device, for example, the input device 2 for BGM, is supplied only to the specific speaker 24. In addition, the semiconductor switch can be switched. These switching states are stored in a storage unit, for example, the memory 32 as a pattern corresponding to the control signal from each input device 2.
[0018]
When an input device 2 starts operating, a control signal from the input device 2 is supplied to the CPU 14 via the input / output interface 12, and the CPU 14 reads a pattern corresponding to the input control signal from the memory 32, and Each semiconductor switch is switched according to the pattern. Such switching is performed every time a control signal is supplied.
[0019]
These patterns are stored in the memory 32 by the user using the operation unit 34 and the display device 36 connected to the CPU 14. When a predetermined key of the operation unit 34 is operated, a table having a plurality of cells arranged vertically and horizontally as shown in FIG. 2 is displayed. In each cell in the leftmost row of this table, the numbers assigned to the input lines 26 corresponding to the respective input devices are displayed. Each cell in the uppermost column of this table displays a number assigned to each output line 28 corresponding to each speaker 24.
[0020]
In this state, the cursor moves on each cell by operating the cursor keys 34U, 34D, 34R, and 34L provided on the operation unit 34. When the cursor is moved to a desired position cell and the mark 34M is operated, the mark is displayed at the cell position. Thereby, it is determined that the input line of the row and the output line of the column where the inverted cell intersects are connected. Hereinafter, similarly, each output line 28 to which a certain input device 2 is connected is determined as one pattern. Similarly, each output line 28 to which another input device 2 is connected is stored as a pattern. When this determination is completed, the determined pattern is stored in the memory 32 when the F-5 key of the operation unit 34 is operated. Although various functions are assigned to the other function keys F-1 to F-4, they are not directly related to the gist of the present invention, and thus description thereof is omitted.
[0021]
As described above, a pattern corresponding to each input device 2 is determined, but a certain speaker 24 may be in a state in which audio signals are supplied from a plurality of input devices 2, that is, in a competitive state. For example, in-store broadcasting may be performed while BGM is being broadcast. In such a case, it is necessary to determine which input device 2 should give priority to the audio signal.
[0022]
Further, when the priority order is determined, not all patterns are given different priority orders, but some patterns may be given the same priority order. In such a case, it is necessary to determine how to process the patterns having the same priority order. As this processing, for example, priority is given to the broadcast that has been performed first, and after this broadcast is finished, the preemptive style of performing the broadcast based on the pattern later, and the broadcast that has been performed earlier are interrupted immediately. There is a follow-up style of broadcasting based on later patterns. You need to decide which style to choose.
[0023]
A speaker that broadcasts an audio signal from one input device 2 and a speaker that broadcasts an audio signal from another input device may partially overlap. The pattern with higher priority may have a smaller number of speakers. For example, in a certain pattern, broadcasting is performed to A and B among four speakers A to D, but in another pattern, broadcasting is performed to three speakers B, C, and D. Then, if the certain pattern has a higher priority, when broadcasting is performed in the other pattern, when broadcasting is started in the certain pattern, the C and D speakers suddenly broadcast. Stay interrupted. Whether it should remain as it is, that is, lockout on, or for C and D speakers that do not broadcast in a certain pattern, continue broadcasting in another pattern, that is, lock It is necessary to decide whether to turn off or not.
[0024]
Therefore, when a specific key of the operation unit is operated, a table having a plurality of cells as shown in FIG. 3 is displayed. In each cell in the leftmost table of this table, the number assigned to the input line 26 corresponding to each input device 2 is displayed. Also, in the explanation of each column at the upper end of this table, from the left, Pri indicating priority, Style indicating style, and Lout indicating lockout are displayed.
[0025]
Here, for example, each time the cursor keys 34U, 34D, 34R, and 34L are operated to move the cursor sequentially to each row of Pri and the function key F-1 is operated, the numerical value displayed in the cell is incremented by one. growing. Conversely, each time the function key F-2 is operated, the numerical value displayed in the cell decreases by one. In this way, priority is set for each row of Pri.
[0026]
In each line of Style, FIFO representing prefetch is displayed as a default value. Here, for example, when the cursor is moved to any cell of the input lines 3, 4 and 5 to which the same priority is assigned and the function key F-1 or F-2 is operated, each cell having the same priority is assigned. Changes to LIFO indicating boost.
[0027]
In addition, in each row of Lout, nothing is displayed as a default value, and in this state, the lockout is off. Here, by moving the cursor on the cell corresponding to the input line to be locked out and operating the mark key 34, a mark is displayed in the cell. In the same manner, a mark is displayed on the cell corresponding to the input line to be locked off.
[0028]
In this way, when all the settings are completed, the settings relating to the priority, style and lockout are stored in the memory by operating the function key F-5.
[0029]
Each time a control signal is supplied from the input device 2, the CPU 14 controls each semiconductor switch in the matrix 10 according to each pattern, priority, style, and lockout stored in the memory.
[0030]
At this time, a table as shown in FIG. 4 is displayed by operating a specific key of the operation unit 34. In this table, the cells in the leftmost row represent the input lines corresponding to the input device 2, and the cells in the uppermost column represent the output lines corresponding to the speakers. Each time a control signal is supplied from the input device 2 to the CPU 14 and the matrix circuit 10 is controlled by the CPU 14, the CPU 14 displays a mark on a cell that is an intersection of the input line and the output line connected to each other. To do. Of course, when the same priority pattern conflicts, the display does not change if a preemption instruction is given, but the display changes if a preemption instruction is given. Furthermore, when the lockout is turned off and broadcasting based on a plurality of patterns is performed simultaneously, the situation is displayed.
[0031]
In this way, it is possible to monitor the situation in which broadcasting is currently being performed by looking at the display on the display unit 36, and the display changes every time the situation of the matrix changes. The later state is instantly represented.
[0032]
In the above embodiment, the operation unit 34 is provided separately from the display unit 36, but a touch panel provided on the display unit 36 can also be used as the operation unit.
[0033]
【The invention's effect】
As described above, according to the first aspect of the present invention, whenever the energized sound source changes, the matrix is controlled according to the pattern corresponding to the energized sound source, and the sound of the energized sound source is desired. However, since the matrix is controlled and displayed on the display means, it is possible to monitor which sound source is currently broadcasting how.
[0034]
In the second aspect of the present invention, when the speakers broadcast by the energized sound source compete, the race condition is resolved according to a predetermined priority order. This can be confirmed by looking at the display on the display means.
[0035]
In the third aspect of the present invention, when the same priority pattern conflicts, the conflict is resolved by the designated method. The display on the display means checks whether this conflict has been resolved as scheduled. Can be confirmed.
[0036]
According to the fourth aspect of the present invention, when patterns with different priorities compete, the pattern with higher priority is processed with priority. The processing method when the number is different and the speaker of the previous pattern includes non-competing speakers is predetermined, but it is confirmed by looking at the display means whether broadcasting is performed according to the processing method can do.
