Summary of the Invention

Problems to be Solved by the Invention

[0004] When distributing content, the content distributor operates the audio equipment. However, the distributor is performing a performance or the like that actually produces sound (for example, playing a musical instrument). In this case, the distributor will hear the sound generated by their own performance. On the other hand, the content listener only hears the distributed sound. Therefore, the distributor cannot operate the audio equipment while listening to the same sound as the listeners receiving the content distribution. In other words, the distributor cannot operate the audio equipment under the same conditions and environment as other terminals receiving the content distribution.

[0005] An object of one embodiment of the present invention is to provide an acoustic processing method that enables an operator of audio equipment to perform acoustic processing of the distribution source (acoustic processing of content) under the same conditions and environment as other terminals receiving content distribution.

Means for Solving the Problems

[0006] An acoustic processing method according to an embodiment of the present invention is as follows: A distributor terminal used by a distributor of content is connected to an acoustic device that performs acoustic processing related to the content. The distributor terminal distributes the content to one or more listener terminals. The distributor terminal designates an operating listener terminal that permits a change operation of the acoustic processing parameters of the acoustic device among the one or more listener terminals. The operating listener terminal accepts the change of the acoustic processing parameters. The operating listener terminal transmits the changed acoustic processing parameters of the acoustic device to the acoustic device via the distributor terminal. The acoustic device executes acoustic processing based on the acoustic processing parameters received from the operating listener terminal.

Advantages of the Invention

[0007] According to the acoustic processing method according to an embodiment of the present invention, an operator can perform acoustic processing of a distribution source under the same conditions and environment as other terminals receiving content distribution.

MODE FOR CARRYING OUT THE INVENTION

[0009] (First Embodiment) Hereinafter, the terminal according to the first embodiment will be described with reference to the drawings. FIG. 1 is a block diagram showing an example of the connection of the distributor terminal 10, the listener terminal 20, and the audio device 30. FIG. 2 is a block diagram showing an example of the configuration of the distributor terminal 10. FIG. 3 is a block diagram showing an example of the configuration of the audio device 30.

[0010] The distributor terminal 10 is a terminal that distributes content. As shown in FIG. 1, the distributor terminal 10 is used by the content distributor U. The distributed content is viewed by one or more listeners L. That is, the distributor terminal 10 distributes the content to one or a plurality of listener terminals 20. The distributor terminal 10 is connected to one or a plurality of listener terminals 20 via, for example, a communication line. The communication line is, for example, an Internet line. In the present embodiment, the distributor terminal 10 performs distribution with real-time performance. In this case, the distribution is, for example, streaming distribution or the like. Such distribution can be performed, for example, by constructing a virtual server or the like for distribution in the distributor terminal 10.

[0011] Note that the communication line does not necessarily have to be an Internet line. The distributor terminal 10 and the listener terminal 20 may communicate via a private network or the like that is not Internet-connected.

[0012] As shown in FIG. 2, the distributor terminal 10 includes a communication interface 100, a flash memory 102, a RAM (Random Access Memory) 103, a user interface 104, and a processing unit 105.

[0013] As shown in FIG. 2, the communication interface 100 communicates with a device different from the distributor terminal 10 (hereinafter referred to as an external device) via a signal line. The distributor terminal 10 and the external device are connected by wire such as an acoustic cable or wirelessly such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). The communication interface 100 includes, for example, USB, HDMI (registered trademark), a network interface, an audio interface, and a MIDI interface. In the present embodiment, the distributor terminal 10 and the listener terminal 20 are connected via a network interface.

[0014] The flash memory 102 stores various data. Specifically, the various data are programs and data for realizing the functions of the distributor terminal 10. For example, the flash memory 102 stores data for content distribution. The flash memory 102 also stores a program for establishing a connection between the distributor terminal 10 and the listener terminal 20, a program for transmitting and receiving data between the distributor terminal 10 and the listener terminal 20, and the like. Such programs include, for example, a program for encoding signals, a program for transmitting and receiving encoded signals, and the like.

[0015] The RAM 103 temporarily stores the data stored in the flash memory 102.

[0016] The user interface 104 inputs and outputs the operations of the distributor U. Thereby, in the present embodiment, the distributor U causes the distributor terminal 10 to execute operations related to distribution. Operations related to distribution are, for example, volume adjustment of distribution. Such a user interface 104 is, for example, a keyboard, a mouse, a touch panel, or the like.

[0017] The processing unit 105 controls the operation of the distributor terminal 10. Specifically, the processing unit 105 performs various operations by reading the program stored in the flash memory 102 into the RAM 103. Such a processing unit 105 is, for example, a CPU (Central Processing Unit). Note that the program does not necessarily need to be stored in the flash memory 102. For example, the processing unit 105 may download a program from a device different from the distributor terminal 10 via a network. Then, the processing unit 105 may read the downloaded program into the RAM 103.

[0018] As described above, the distributor terminal 10 is, for example, a PC, a smartphone, or the like.

[0019] In the present embodiment, the content is, for example, content related to sounds such as performances. Therefore, the distributor terminal 10 acquires a sound signal subjected to acoustic processing. Specifically, the sound signal is a digital signal obtained by sampling sound at a predetermined sampling rate. The distributor terminal 10 transmits the sound signal to one or a plurality of listener terminals 20. The method by which the distributor terminal 10 obtains the sound signal is, for example, a method of inputting the sound signal from the acoustic device 30 as shown in FIGS. 1 and 2. The acoustic device 30 performs adjustment of the sound signal and output of the sound signal, etc. Therefore, in the present embodiment, the acoustic device 30 executes acoustic processing related to the content. Specifically, as shown in FIGS. 1 and 2, the distributor terminal 10 is connected to the acoustic device 30. More specifically, the distributor terminal 10 is connected to the acoustic device 30 via the communication interface 100. The distributor terminal 10 receives the sound signal obtained by acoustic processing from the acoustic device 30. The distributor terminal 10 transmits the received sound signal to the listener terminal 20.

[0020] The audio device 30 executes audio processing based on the audio processing parameter Pa. The audio processing parameter Pa is a parameter related to audio processing such as gain control and mixing. The audio processing parameter Pa includes, for example, a gain value, a mix balance value, and the like. When the value of the audio processing parameter Pa is changed, the content of the audio processing executed by the audio device 30 changes. For example, when the audio processing parameter Pa is a gain value, the amplification amount of the audio signal is changed by increasing or decreasing the gain value. Note that the audio processing executed by the audio device 30 is not limited to only gain control and mixing. For example, the audio device 30 may execute audio processing such as equalizing and compressing. In other words, the audio processing parameter Pa may include other values than the gain value and the mix balance value.

[0021] As shown in FIG. 3, the audio device 30 includes a communication interface 300, a DSP (Digital Signal Processor) 301, a flash memory 302, a RAM 303, and a processing unit 305.

[0022] The communication interface 300 communicates with an external device different from the audio device 30. In other words, the audio device 30 communicates with the distributor terminal 10 via the communication interface 300. Also, as shown in FIG. 3, the communication interface 300 communicates with an external device 40 different from the distributor terminal 10. The external device 40 includes an audio device. Therefore, as shown in FIG. 3, the external device 40 is a speaker, a microphone, or the like. The communication interface 300 is, for example, USB or HDMI (registered trademark). Note that the external device 40 and the audio device 30 may be connected by an interface such as an audio interface and a MIDI interface.

[0023] The DSP 301 performs signal processing on the audio signal. The signal processing is, for example, audio processing such as gain control and mixing.

[0024] The flash memory 302 stores various programs. The various programs are, for example, programs for operating the audio device 30 and the like. Further, the flash memory 302 stores the audio processing parameter Pa related to audio processing.

[0025] The RAM 303 temporarily stores a predetermined program stored in the flash memory 302.

[0026] The processing unit 305 controls the operation of the audio device 30. Specifically, the processing unit 305 performs various operations by reading a predetermined program stored in the flash memory 302 into the RAM 303. Such a processing unit 305 is, for example, a CPU. Note that the program does not necessarily have to be stored in the flash memory 302 inside the audio device 30. For example, the processing unit 305 downloads a program from an external device of the audio device 30 via a network. Then, the processing unit 305 may read the downloaded program into the RAM 303.

[0027] The audio device 30 as described above is, for example, a mixer or the like.

[0028] Incidentally, the distributor terminal 10 according to the present embodiment has a function of causing the listener L to operate the audio device 30 at the timing desired by the distributor U. Hereinafter, this function will be described with reference to FIGS. 1 and 4. FIG. 4 is a flowchart showing an example of the processing of the distributor terminal 10 and the listener operation terminal TR.

[0029] First, the distributor U starts the distribution of the content. Specifically, the distributor terminal 10 distributes the content to one or more listener terminals 20 (FIG. 4: step S11). In the example shown in FIG. 1, each of the listeners La, Lb, and Lc is listening to the distribution via the listener terminals 20a, 20b, and 20c.

[0030] Next, the distributor U designates an operator LL who will transfer the operation authority of the audio device 30 from among the listeners L who are listening to the distribution. Specifically, the distributor terminal 10 designates an operation listener terminal TR that performs a change operation on the audio processing parameter Pa of the audio device 30 among one or more listener terminals 20 (Fig. 4: step S12). In the case of the example shown in Fig. 1, a plurality of listener terminals 20 (listener terminals 20a, 20b, 20c) are connected to the distributor terminal 10. Here, when the distributor U wants the listener Lc to operate the audio device 30, the distributor U designates the listener terminal 20c as the operation listener terminal TR via the distributor terminal 10. By this designation, the operation of the audio device 30 by the operation listener terminal TR is permitted. As a result, the operation listener terminal TR can operate the audio device 30. In this case, the listener Lc becomes the operator LL who operates the audio device 30.

[0031] Next, the operator LL changes the acoustic processing parameter Pa via the operation listener terminal TR. That is, the operation listener terminal TR accepts the change of the acoustic processing parameter Pa (Figure 4: Step S13). In the example shown in Figure 1, the operation listener terminal TR includes a display unit TRD. In this case, for example, the display unit TRD displays a GUI (Graphical User Interface) related to the operation of the acoustic processing parameter Pa. Thereby, the operator LL changes the acoustic processing parameter Pa via the GUI. In the example shown in Figure 1, the display unit TRD displays a fader, a knob, etc. as the GUI. In the example shown in Figure 1, the fader is a GUI related to the change of the gain value. Therefore, when the operator LL wants to change the gain value, the fader is operated. In the example shown in Figure 1, the knob is a GUI related to the adjustment of the mix balance. Therefore, when the operator LL wants to adjust the mix balance, the knob is operated. The operation listener terminal TR detects the operation of the GUI by the operator LL. Then, the operation listener terminal TR stores the value of the acoustic processing parameter Pa based on the operation of the GUI in the storage device of the operation listener terminal TR. Hereinafter, the changed acoustic processing parameter Pa is referred to as the acoustic processing parameter PaAf. Note that since the method of using the GUI in the change of the acoustic processing parameter Pa is an example, it is not necessarily required to accept the change of the acoustic processing parameter Pa by the GUI.

[0032] Next, the operation listener terminal TR transmits the changed acoustic processing parameter PaAf to the audio device 30 (Figure 4: Step S14). Specifically, the operation listener terminal TR transmits the acoustic processing parameter PaAf to the distributor terminal 10. The distributor terminal 10 that has received the acoustic processing parameter PaAf transmits the acoustic processing parameter PaAf to the audio device 30.

[0033] Finally, the audio device 30 executes audio processing based on the audio processing parameter PaAf received from the operation listener terminal TR (Fig. 4: step S15). Specifically, the previous audio processing parameter PaBe is recorded in the flash memory 302 of the audio device 30. The audio device 30 updates the audio processing parameter PaBe to the received audio processing parameter PaAf. As a result, the audio device 30 executes audio processing based on the audio processing parameter PaAf set by the operator LL. Consequently, the listener L can listen to the sound based on the operation of the operator LL.

[0034] If the content is being distributed, the distributor terminal 10, the operation listener terminal TR, and the audio device 30 can repeatedly perform the processes from step S12 to step S15.

[0035] The processes shown above are executed, for example, by using a GUI program. Specifically, as shown in Fig. 2, the flash memory 102 of the distributor terminal 10 stores the GUI program P1. Then, the distributor terminal 10 and the operation listener terminal TR read out and expand the GUI program P1. In this embodiment, the GUI program P1 is, for example, a web application program. Therefore, the distributor terminal 10 and the operation listener terminal TR can operate the audio device 30 via a general-purpose web browser. Hereinafter, a series of processes will be described in detail with reference to the drawings. Fig. 5 is a flowchart showing an example of the processing of the distributor terminal 10 when using the GUI program P1. In Fig. 5, the start of the processing (Fig. 5: START) is when the distributor terminal 10 starts distributing the content.

[0036] First, the distributor terminal 10 deploys the GUI program P1 to its own device (Fig. 5: step S101). After the deployment, the distributor terminal 10 starts accepting the designation of the operation listener terminal TR (Fig. 5: step S102). As a result, the distributor U can designate the operation listener terminal TR via the distributor terminal 10. In this case, the distributor terminal 10 designates the operation listener terminal TR from among the listener terminals 20 that are receiving content distribution. Specifically, the listener terminal 20 connects to the distributor terminal 10 that is the distribution source. At this time, the listener terminal 20 receives content distribution from the distributor terminal 10 and transmits information about its own device to the distributor terminal 10 (Fig. 5: step S200). The distributor terminal 10 acquires the information of the listener terminal 20 that is receiving content distribution. Then, the distributor terminal 10 displays the information of the listener terminal 20, for example, via the GUI. Based on the information of the listener terminal 20, the distributor U designates the operation listener terminal TR (operator LL). The information of the listener terminal 20 is, for example, information such as a handle name previously set in the listener terminal 20 by the listener L. In this case, the distributor terminal 10 causes, for example, a list of handle names to be displayed on a display unit (not shown) provided in the distributor terminal 10. At this time, for example, the distributor U designates the operation listener terminal TR by selecting a handle name via the GUI. Thereby, the distributor U can select the operator LL based on the handle name. Note that the information of the listener terminal 20 is not limited to the handle name. The information of the listener terminal 20 may be, for example, the IP address, MAC address, etc. of the listener terminal 20.

[0037] After designating the operation listener terminal TR, the distributor terminal 10 transmits a connection request to the operation listener terminal TR (Fig. 5: step S103). The operation listener terminal TR receives the connection request (Fig. 5: step S204). After receiving the connection request, the operation listener terminal TR transmits a connection request to the GUI program P1 to the distributor terminal 10 (Fig. 5: step S205). The distributor terminal 10 receives the connection request to the GUI program P1 (Fig. 5: step S106).

[0038] After step S106, the distributor terminal 10 deploys the GUI program P1 to the operation listener terminal TR (Fig. 5: step S207). Thereby, the operation listener terminal TR can change the acoustic processing parameter Pa via the GUI program P1.

[0039] After step S207, the operation listener terminal TR accepts a change operation of the acoustic processing parameter Pa (Fig. 5: step S208). Thereby, the operator LL can change the acoustic processing parameter Pa. After changing the acoustic processing parameter Pa, the operation listener terminal TR transmits the acoustic processing parameter PaAf to the distributor terminal 10 (Fig. 5: step S209). Specifically, the GUI program P1 executes an instruction to transmit the acoustic processing parameter PaAf to the acoustic device 30 for the operation listener terminal TR. Thereby, the operation listener terminal TR transmits the acoustic processing parameter PaAf to the distributor terminal 10.

[0040] After step S209, the distributor terminal 10 receives the acoustic processing parameter PaAf (Fig. 5: step S110). After receiving the acoustic processing parameter PaAf, the distributor terminal 10 transmits the acoustic processing parameter PaAf to the acoustic device 30 (Fig. 5: step S111). Such deployment of the GUI program P1 and transmission / reception of the acoustic processing parameter PaAf are performed, for example, by constructing P2P (Peer To Peer) between the distributor terminal 10 and the operation listener terminal TR. Then, the operation listener terminal TR transmits the acoustic processing parameter PaAf to the distributor terminal 10 via P2P.

[0041] After step S111, the acoustic device 30 receives the acoustic processing parameter PaAf (Fig. 5: step S312). After receiving it, the acoustic device 30 updates the value of the acoustic processing parameter PaBe stored in the flash memory 302 to the value of the acoustic processing parameter PaAf (Fig. 5: step S313). After the update, the acoustic device 30 executes acoustic processing based on the acoustic processing parameter PaAf (Fig. 5: step S314).

[0042] As described above, the operation listener terminal TR can operate the audio device 30 via the GUI program P1. Note that the method by which the operation listener terminal TR transmits the audio processing parameter Pa to the audio device 30 is not limited to the example using the GUI program P1. For example, the operation listener terminal TR may operate the audio device 30 by remotely operating the distributor terminal 10. For example, the distributor terminal 10 deploys a program for operating the audio device 30. Then, the operation listener terminal TR makes a remote connection to the distributor terminal 10. The remote connection is made, for example, by constructing P2P between the distributor terminal 10 and the operation listener terminal TR. Then, the operation listener terminal TR operates the distributor terminal 10 via P2P. Thereby, the operation listener terminal TR can operate the audio device 30 via the distributor terminal 10.

[0043] (Effect of the First Embodiment) According to the distributor terminal 10, the listener L can be remotely operated to operate the audio device 30 at the timing desired by the distributor U. More specifically, the distributor terminal 10 is used by the content distributor U. The distributor terminal 10 is connected to an audio device 30 that performs audio processing related to the content. The distributor terminal 10 distributes the content to one or more listener terminals 20. The distributor terminal 10 designates an operating listener terminal TR that performs an operation to change the audio processing parameter Pa of the audio device 30 among the one or more listener terminals 20. The operating listener terminal TR receives a change in the audio processing parameter Pa from the listener L. The operating listener terminal TR transmits the changed audio processing parameter Pa to the audio device 30 via the distributor terminal 10. Then, the audio device 30 executes audio processing based on the audio processing parameter Pa received from the operating listener terminal TR. With the above configuration, the distributor U can transfer the authority to operate the audio device 30 to the listener L via the distributor terminal 10 at the timing desired by the distributor U. Then, the listener L to whom the authority is transferred operates the audio device 30. As a result, the listener L can be remotely operated to operate the audio device 30 at the timing desired by the distributor U. The distributor U can concentrate on the distribution without having to worry about the operation of the audio device 30. Also, when the distributor U transfers the operation authority to a listener L who is accustomed to operating the audio device 30, the distribution can be performed with better audio settings.

[0044] Furthermore, according to the above configuration, it is not the distributor U but the listener L (i.e., the operator LL) who is receiving the content distribution that operates the audio device 30 while listening to the sound of the distributed content. Therefore, in the present embodiment, the operator LL who operates the audio device 30 can perform audio processing (content audio processing) under the same conditions and environment as other listeners who are receiving the content distribution.

[0045] (Second Embodiment) Hereinafter, the distributor terminal 10a according to the second embodiment will be described with reference to the drawings. FIG. 6 is a flowchart showing an example of the processing of the distributor terminal 10a when the GUI program P2 is used. In FIG. 6, the processing different from that of the first embodiment is marked with dot patterns.

[0046] The distributor terminal 10a is different from the distributor terminal 10 in that it causes the operation listener terminal TR to display the acoustic processing parameter Pa set in the acoustic device 30. Specifically, the operation listener terminal TR includes a display unit TRD. In the present embodiment, the display unit TRD corresponds to the listener display unit. After designating the operation listener terminal TR, the distributor terminal 10a causes the display unit TRD to display information related to the acoustic processing parameter PaBe. Such processing is executed, for example, when the distributor terminal 10b and the operation listener terminal TR read and expand the GUI program P2 (see FIG. 6).

[0047] The details will be described below. After the distributor terminal 10a designates the operation listener terminal TR, the distributor terminal 10a acquires the acoustic processing parameter PaBe set in the acoustic device 30 from the acoustic device 30. Specifically, after step S207, the distributor terminal 10a requests the acoustic device 30 to transmit the acoustic processing parameter PaBe (FIG. 6: step S2001). Next, the acoustic device 30 receives the request for transmitting the acoustic processing parameter PaBe (FIG. 6: step S2002). Next, the acoustic device 30 transmits the acoustic processing parameter PaBe stored in the acoustic device 30 to the distributor terminal 10a (FIG. 6: step S2003). The distributor terminal 10a receives the acoustic processing parameter PaBe (FIG. 6: step S2004).

[0048] Next, the distributor terminal 10a transmits the acoustic processing parameter PaBe set in the acoustic device 30 to the operation listener terminal TR (FIG. 6: step S2005).

[0049] After the operation listener terminal TR receives the acoustic processing parameter PaAf (Fig. 6: step S2006), the display unit TRD displays the acoustic processing parameter PaBe set in the received acoustic device 30 (Fig. 6: step S2007). For example, if the value of gain = 10 dB is set as the acoustic processing parameter PaBe in the acoustic device 30, the operation listener terminal TR acquires the parameter of gain = 10 dB. The GUI program P2 causes the display unit TRD to display the information indicating gain = 10 dB. For example, the GUI program P2 causes the display unit TRD to display the text message of gain = 10 dB.

[0050] After the process of step S2007, the distributor terminal 10a, the operation listener terminal TR, and the acoustic device 30 execute the processes from step S208 to step S314.

[0051] Note that the method by which the distributor terminal 10a causes the operation listener terminal TR to display the acoustic processing parameter PaBe is not limited to the method using the GUI program P2.

[0052] (Effect of the Second Embodiment) According to the distributor terminal 10a, it becomes easier for the operator LL to adjust the acoustic processing parameter Pa. Specifically, the distributor terminal 10a acquires the acoustic processing parameter PaBe set in the acoustic device 30 from the acoustic device 30. The distributor terminal 10a transmits the acoustic processing parameter PaBe set in the acoustic device 30 to the operation listener terminal TR. The operation listener terminal TR displays the acoustic processing parameter PaBe set in the received acoustic device 30. With the above configuration, before changing the acoustic processing parameter Pa, the operator LL can know the value of the acoustic processing parameter PaBe and the like. Therefore, the operator LL can determine the adjustment amount of the acoustic processing parameter Pa based on the value of the acoustic processing parameter PaBe and the like. Therefore, the operator LL can accurately adjust the acoustic processing parameter Pa.

[0053] (Third Embodiment) Hereinafter, the distributor terminal 10b according to the third embodiment will be described with reference to the drawings. FIG. 7 is a flowchart showing an example of the processing of the distributor terminal 10b when using the GUI program P3. In FIG. 7, the processing different from that of the first embodiment is marked with a dot pattern.

[0054] The distributor terminal 10b is different from the distributor terminal 10 in that it transmits notification information to the operation listener terminal TR. The notification information is information indicating that it has been designated as the operation listener terminal TR. Such processing is executed, for example, when the distributor terminal 10b and the operation listener terminal TR read and expand the GUI program P3 (see FIG. 7). Details will be described below.

[0055] When the distributor terminal 10b designates the operation listener terminal TR, the distributor terminal 10b transmits notification information indicating the designation to the operation listener terminal TR. Specifically, after the expansion of the GUI program P3 (FIG. 7: after step S207), the distributor terminal 10 transmits the notification information to the operation listener terminal TR (FIG. 7: step S3001). Next, the operation listener terminal TR receives the notification information (FIG. 7: step S3002). Then, the operation listener terminal TR displays information based on the notification information. Specifically, in this embodiment, as shown in FIG. 7, the operation listener terminal TR includes a display unit TRD. The display unit TRD displays information based on the notification information. For example, the distributor terminal 10b transmits a text message "You have been designated as the operation terminal" to the operation listener terminal TR. When the operation listener terminal TR receives the text message, the display unit TRD displays the message "You have been designated as the operation terminal".

[0056] After the display of the notification information (FIG. 7: after step S3003), the distributor terminal 10b, the operation listener terminal TR, and the audio device 30 execute the processing from step S208 to step S314 (see FIG. 7).

[0057] Note that the method by which the distributor terminal 10b causes the operation listener terminal TR to display based on the notification information is not limited to only the method using the GUI program P3.

[0058] (Effect of the Third Embodiment) According to the distributor terminal 10b, it is possible to accurately convey to the listener L that the listener L has been selected as the operator LL. Specifically, when the distributor terminal 10b designates the operation listener terminal TR, the distributor terminal 10b transmits notification information indicating the designation to the operation listener terminal TR. Then, the display unit TRD of the operation listener terminal TR displays information based on the notification information. For example, when using the GUI program P3 or the like, the display of the display unit TRD changes. In this case, the screen display of the terminal of the listener L selected as the operator LL changes. At this time, there is a possibility that the operator LL may be confused due to the change in the screen display. In the case of the configuration of the present embodiment, after the listener L knows that the listener L has been selected as the operator LL, the screen display of the terminal of the operator LL changes. Therefore, for example, even when the display of the display unit TRD changes by the GUI program P3, the possibility that the operator LL is confused is reduced.

[0059] (Fourth Embodiment) Hereinafter, the distributor terminal 10c according to the fourth embodiment will be described with reference to the drawings. FIG. 8 is a flowchart showing an example of the processing of the distributor terminal 10c when using the GUI program P4. In FIG. 8, the processing different from the first embodiment is marked with a dot pattern.

[0060] The content provider terminal 10c is different from the content provider terminal 10 in that it displays the acoustic processing parameter PaAf after being changed by the operator LL. Specifically, as shown in FIG. 8, the content provider terminal 10c includes a display unit 10cD. The display unit 10cD displays the acoustic processing parameter PaAf after being changed by the operation listener terminal TR. More specifically, after step S110 (FIG. 8: step S110), the display unit 10cD displays the acoustic processing parameter PaAf (FIG. 8: step S4001). In the example shown in FIG. 8, the display unit 10cD displays a fader and a knob as the GUI. In FIG. 8, the fader indicates the gain value, and the knob indicates the adjustment value of the mix balance. In other words, in the example shown in FIG. 8, the fader and the knob are displayed based on the value of the acoustic processing parameter PaAf. In the present embodiment, the display unit 10cD corresponds to the content provider display unit.

[0061] After the content provider terminal 10c displays the acoustic processing parameter PaAf (after step S4001 in FIG. 8), the content provider terminal 10c and the audio device 30 execute the processes from step S111 to step S314 (see FIG. 8).

[0062] The processes as described above are executed, for example, when the content provider terminal 10c and the operation listener terminal TR read and expand the GUI program P4 (see FIG. 8). Note that the method by which the content provider terminal 10c displays the acoustic processing parameter PaAf is not limited to the method using the GUI program P4.

[0063] (Effect of the Fourth Embodiment) According to the distributor terminal 10c, the distributor U can check the changed acoustic processing parameter PaAf. More specifically, the distributor terminal 10c includes a display unit 10cD. The display unit 10cD displays the acoustic processing parameter PaAf after being changed by the operation listener terminal TR. Thereby, the distributor U can check based on what acoustic processing parameter PaAf the audio device 30 is outputting sound. Therefore, for example, it becomes possible to check whether the value of the acoustic processing parameter PaAf is what the distributor U desires.

[0064] (Fifth Embodiment) Hereinafter, the distributor terminal 10d according to the fifth embodiment will be described with reference to the drawings. FIG. 9 is a flowchart showing an example of the processing of the distributor terminal 10d when using the GUI program P5. In FIG. 9, the processing different from that of the first embodiment is marked with dot patterns.

[0065] The distributor terminal 10d is different from the distributor terminal 10 in that it can stop the operation of the audio device 30 on the operation listener terminal TR. Specifically, as shown in FIG. 9, after the distributor terminal 10 designates the operation listener terminal TR, it accepts the cancellation of the designation of the operation listener terminal TR. More specifically, after the operation listener terminal TR deploys the GUI program P5 (FIG. 9: after step S207), the distributor terminal 10d starts accepting the cancellation of the designation of the operation listener terminal TR (FIG. 9: step S5001). When the distributor terminal 10d accepts the cancellation of the designation (FIG. 9: step S5002), it cancels the designation of the operation listener terminal TR (FIG. 9: step S5003). For example, the distributor terminal 10d displays a button for accepting the cancellation of the designation on the display unit 10dD of the distributor terminal 10d (see FIG. 9). The distributor U presses the button by an operation such as clicking. The GUI program P5 determines whether the button has been pressed by the distributor U. When the GUI program P5 determines that the button has been pressed, the GUI program P5 disconnects, for example, the communication for operating the audio device 30 with the operation listener terminal TR. Thereby, the operation of the audio device 30 on the operation listener terminal TR is stopped. Note that the method of stopping the operation of the audio device 30 on the operation listener terminal TR is not limited to the method of disconnecting the communication.

[0066] When the distributor terminal 10d does not accept the cancellation of the designation (FIG. 9: step S5002), the distributor terminal 10d, the operation listener terminal TR, and the audio device 30 repeat the processing from step S5002 to step S314.

[0067] Note that the method by which the distributor terminal 10d stops the operation of the audio device 30 on the operation listener terminal TR is not limited to the method using the GUI program P4.

[0068] (Effect of the Fifth Embodiment) According to the distributor terminal 10d, the distributor U can transfer the operation authority of the acoustic processing parameter PaAf to the operator LL only when necessary. More specifically, after specifying the listener terminal TR for operation, the distributor terminal 10d accepts the cancellation of the specification of the listener terminal TR for operation. When the distributor terminal 10d accepts the cancellation of the specification, it cancels the specification of the listener terminal TR for operation. In the case of the above configuration, when the distributor U considers that the operation of the acoustic device 30 by the operator LL is unnecessary, the operation of the acoustic device 30 by the operator LL can be stopped.

[0069] (Sixth Embodiment) Hereinafter, the distributor terminal 10e according to the sixth embodiment will be described with reference to the drawings. FIG. 10 is a block diagram showing an example of the connection between the distributor terminal 10e, the listener terminal 20, and the server 60e. FIG. 11 is a flowchart showing an example of the processing of the distributor terminal 10e when the GUI program P6 is used. In FIG. 11, the communication via the server 60e is described by dotted arrows. Hereinafter, the communication via the server 60e will be referred to as communication Co60.

[0070] The distributor terminal 10e is different from the distributor terminal 10 in that it distributes content via one or more listener terminals 20 and the server 60e. This will be described in detail below.

[0071] As shown in FIG. 10, the server 60e includes a flash memory 602, a RAM 603, and a processing unit 605. The processing unit 605 performs various operations by reading a predetermined program stored in the flash memory 602 into the RAM 303. As shown in FIG. 10, the distributor terminal 10e is connected to the server 60e. The listener terminal 20 is connected to the server 60e. The server 60e stores information related to the communication between the distributor terminal 10e and the listener terminal 20. The information related to the communication is, for example, routing information and the like. Thereby, the distributor terminal 10e transmits the sound signal input from the audio device 30 to the listener terminal 20 via the server 60e. Specifically, as shown in FIG. 11, the operation listener terminal TR transmits the information of its own device to the distributor terminal 10 by communication Co60 (FIG. 11: step S200). Further, the distributor terminal 10e transmits a connection request to the operation listener terminal TR by communication Co60 (FIG. 11: step S103). Further, the operation listener terminal TR transmits a connection request to the GUI program P6 to the distributor terminal 10e by communication Co60 (FIG. 11: step S205). In other words, the distributor terminal 10e designates, via the server 60e, the operation listener terminal TR that performs the change operation of the audio processing parameter Pa of the audio device 30 among one or more listener terminals 20. Further, the operation listener terminal TR transmits the audio processing parameter PaAf to the distributor terminal 10e by communication Co60 (FIG. 11: step S209). In other words, the operation listener terminal TR transmits the changed audio processing parameter PaAf to the audio device 30 via the server 60e.

[0072] (Effect of the Sixth Embodiment) According to the distributor terminal 10e and the server 60e, the processing speed in the distributor terminal 10e is improved. Specifically, the distributor terminal 10e distributes content to one or more listener terminals 20 via the server 60e. The distributor terminal 10e designates, via the server 60e, an operation listener terminal TR that performs an operation to change the acoustic processing parameter Pa of the acoustic device 30 among one or more listener terminals 20. The operation listener terminal TR transmits the changed acoustic processing parameter Pa to the acoustic device 30 via the server 60e. With the above configuration, the server 60e executes processing related to the communication between the distributor terminal 10e and the listener terminal 20. The processing related to communication is, for example, routing processing between the distributor terminal 10e and the listener terminal 20. Thereby, the distributor terminal 10e does not have to execute processing related to communication with the listener terminal 20. Therefore, the number of processes executed in parallel in the distributor terminal 10e is reduced. As a result, the processing speed in the distributor terminal 10e is improved.

[0073] (Modification Example 1 of the Sixth Embodiment) Hereinafter, the distributor terminal 10e2 and the server 60e2 according to Modification Example 1 of the Sixth Embodiment will be described with reference to FIG. 12. FIG. 12 is a flowchart showing an example of communication between the distributor terminal 10e2 according to Modification Example 1 of the Sixth Embodiment, the server 60e2, and the operation listener terminal TR. In FIG. 12, processes different from those in the Sixth Embodiment are marked with dot patterns.

[0074] In this modification, the server 60e2 is a distribution server that distributes content to one or more listener terminals 20. In other words, the server 60e2 executes processing related to content distribution instead of the distributor terminal 10e2. Therefore, the server 60e2 stores a program or the like related to content distribution. On the other hand, the distributor terminal 10e2 does not have to store a program or the like related to content distribution. Hereinafter, the processing flow will be described in detail.

[0075] As shown in FIG. 12, the distributor terminal 10e2 transmits a connection request to the server 60e2 (FIG. 12: step S7001). The server 60e2 receives the connection request (FIG. 12: step S7002). After receiving the connection request, the server 60e2 deploys a program related to content distribution. After deployment, content distribution is started by the distributor terminal 10e2 and the server 60e2 (FIG. 12: step S7003). Since the processing after content distribution is the same as the processing described in the sixth embodiment, the description thereof is omitted.

[0076] (Effect of Modification Example 1 of the Sixth Embodiment) According to the distributor terminal 10e2 and the server 60e2, the processing speed of the distributor terminal 10e2 is improved. Specifically, the server 60e2 is a distribution server that distributes content to one or more listener terminals 20. In the case of the above configuration, the server 60e2 executes processing related to content distribution in addition to processing related to communication between the distributor terminal 10e and the listener terminal 20. Thereby, the distributor terminal 10e2 does not have to execute processing related to content distribution. Therefore, the number of processes executed in parallel in the distributor terminal 10e2 is reduced. As a result, the processing speed in the distributor terminal 10e2 is improved.

[0077] (Modification Example 2 of the Sixth Embodiment) Hereinafter, the distributor terminals 10e3 and 10e4, and the servers 60e3 and 60e4 according to Modification Example 2 of the sixth embodiment will be described with reference to the drawings. FIG. 13 is a block diagram showing an example of the connection between the distributor terminal 10e3, the server 60e3, and the listener terminal 20 according to Modification Example 2 of the sixth embodiment. FIG. 14 is a flowchart showing an example of communication between the distributor terminal 10e3, the server 60e3, and the operation listener terminal TR according to Modification Example 2 of the sixth embodiment. In FIG. 14, the processing different from that in the sixth embodiment is marked with a dot pattern. FIG. 15 is a block diagram showing an example of the connection between the distributor terminal 10e4, the server 60e4, and the operation listener terminal TR according to Modification Example 2 of the sixth embodiment.

[0078] In this modification example, as shown in FIG. 13, the server 60e3 stores the GUI program P6Sv instead of the distributor terminal 10e3. Specifically, the flash memory 602 of the server 60e3 stores the GUI program P6Sv. The distributor terminal 10e3 reads the GUI program P6Sv from the server 60e3. Specifically, the distributor terminal 10e3 sends a connection request to the GUI program P6Sv to the server 60e3 (FIG. 14: step S8001). The server 60e3 receives the connection request to the GUI program P6Sv (FIG. 14: step S8002). The server 60e3 deploys the GUI program P6Sv to the distributor terminal 10e3 (FIG. 14: step S8003).

[0079] Also, the operation listener terminal TR reads the GUI program P6Sv from the server 60e3. Specifically, the operation listener terminal TR sends a connection request to the GUI program P6Sv to the server 60e3 (FIG. 14: step S8004). The server 60e3 receives the connection request to the GUI program P6Sv (FIG. 14: step S8005). The server 60e3 deploys the GUI program P6Sv to the operation listener terminal TR (FIG. 14: step S8006).

[0080] The processing described in the sixth embodiment is the same as that described above except that the GUI program P6Sv is read from the server 60e3, so the description is omitted.

[0081] As shown in FIG. 15, the distributor terminal 10e4 and the listener terminal 20 may not be connected via the server 60e4. In this case, the server 60e4 only executes the deployment of the GUI program P6Sv to the distributor terminal 10e4 and the deployment of the GUI program P6Sv to the operation listener terminal TR.

[0082] Note that the designation of the operation listener terminal TR by the distributor terminal 10e3 may be, for example, a method using a password. For example, the distributor U sets a password for the server 60e3 via the distributor terminal 10e3. Then, when the operation listener terminal TR makes a connection request to the GUI program P6Sv to the server 60e3, the server 60e3 requests the operation listener terminal TR to send a password. When the password is input, the server 60e3 deploys the GUI program P6Sv to the operation listener terminal TR. In this case, for example, the password may be sent from the distributor terminal 10e3 to the operation listener terminal TR by a text message or the like.

[0083] (Modification Example 1 from the First Embodiment to the Sixth Embodiment) Hereinafter, the distributor terminal 10f (not shown) according to Modification Example 1 will be described. The distributor terminal 10f is different from the distributor terminal 10 in that it deploys a preview function to the operation listener terminal TR. The preview function is a function that can simulate the result of acoustic processing based on the acoustic processing parameter PaAf before transmitting the acoustic processing parameter PaAf to the acoustic device 30. Thereby, the operator LL can listen to a sound imitating the sound output from the acoustic device 30 before transmitting the acoustic processing parameter PaAf. Therefore, the operator LL can adjust the acoustic processing parameter Pa more accurately.

[0084] (Modification Example 2 from the First Embodiment to the Sixth Embodiment) Next, the distributor terminal 10g (not shown) according to Modification 2 will be described. The distributor terminal 10g is different from the distributor terminal 10 in that it can transfer the operation authority of the audio device 30 to each of a plurality of listeners L. Hereinafter, it will be described by making quasi-reference to FIG. 4. For example, the distributor terminal 10g can transfer the operation related to the gain adjustment to the listener Lb. Similarly, the operation related to the mix balance adjustment can be transferred to the listener Lc. The audio device 30 executes audio processing based on the parameters input from each of the listener terminals 20b and 20c. Thereby, the operator LL can share the adjustment of the audio processing parameter Pa.

[0085] (Modification 3 from the First Embodiment to the Sixth Embodiment) Next, the distributor terminal 10h (not shown) according to Modification 3 will be described. The distributor terminal 10h is different from the distributor terminal 10 in that it can transfer the operation of devices other than the audio device to the listener L. The distributor terminal 10h is used, for example, for distributing video content. In this case, the distributor terminal 10h is connected to a video device. Then, the distributor terminal 10h can transfer the operation authority of the video device to the listener L. Such a video device is, for example, a video switcher or the like. In this case, the operation listener terminal TR is transferred the operation authority for video switching, for example. Note that the distributor terminal 10h may transfer the operation authority of lighting to the listener L instead of transferring the operation authority of the video device, for example. In this case, the distributor terminal 10h is connected to a dimmer. Then, the distributor terminal 10h can transfer the operation authority of the dimmer to the listener L. In this case, the operation listener terminal TR is transferred the operation authority such as the light amount and the ON / OFF of lighting, for example.

[0086] (Modification 4 from the First Embodiment to the Sixth Embodiment) Hereinafter, the distributor terminal 10i (not shown) according to Modification 4 will be described. The distributor terminal 10i is different from the distributor terminal 10 in that the distributor U can select the acoustic processing parameter Pa to transfer the authority to the listener L. Specifically, when specifying the operation listener terminal TR, the distributor terminal 10i accepts the selection of the acoustic processing parameter Pa that permits the change. The distributor terminal 10i permits only the change of the selected acoustic processing parameter Pa to the operation listener terminal TR. For example, when the distributor U selects only the mix balance as the acoustic processing parameter Pa that permits the change, the operation listener terminal TR can adjust only the mix balance. Thereby, the distributor U can have the operator LL adjust only the acoustic processing parameter Pa that the distributor U wants to be adjusted.

[0087] (Other Embodiments) The distributor terminals 10 to 10e according to the present invention are not limited to the distributor terminals 10 to 10e according to the above embodiment, and can be changed within the scope of the gist thereof. Note that the configurations of the distributor terminals 10 to 10e may be arbitrarily combined.

[0088] Note that the distributor terminals 10, 10b to 10e do not necessarily have to acquire the acoustic processing parameter Pa set in the acoustic device 30 from the acoustic device 30. Therefore, the distributor terminals 10, 10b to 10e do not necessarily have to transmit the acoustic processing parameter Pa set in the acoustic device 30 to the operation listener terminal TR. In this case, the operation listener terminal TR does not necessarily have to display the acoustic processing parameter Pa set in the received acoustic device 30.

[0089] Note that the distributor terminals 10, 10a, 10c to 10e do not necessarily have to transmit notification information indicating that the operation listener terminal TR has been specified to the operation listener terminal TR when the operation listener terminal TR is specified.

[0090] Note that the distributor terminals 10 to 10b, 10d, 10e do not necessarily have to display the acoustic processing parameter PaAf after being changed by the operation listener terminal TR.

[0091] In the example shown in FIG. 4, the operation listener terminal TR accepts changes to the acoustic processing parameter Pa by operating the fader or knob displayed on the display unit 200c. However, the method by which the operation listener terminal TR accepts changes to the acoustic processing parameter Pa is not limited to the example of operating the fader or knob. For example, the operation listener terminal TR may accept changes to the acoustic processing parameter Pa based on the numerical value input by the operator LL. For example, the operator LL inputs a value of gain = 20 dB. In this case, the operation listener terminal TR may output the acoustic processing parameter Pa of gain = 20 dB to the audio device 30.

[0092] Note that the distributor terminals 10 to 10c, 10e do not necessarily have to execute a process of canceling the designation of the operation listener terminal TR.

[0093] Note that the distributor terminals 10 to 10d do not necessarily have to distribute the content via the server 60e to one or more listener terminals 20. In other words, the distributor terminals 10 to 10d do not necessarily have to specify the operation listener terminal TR that performs the change operation of the acoustic processing parameter Pa of the audio device 30 among one or more listener terminals 20 via the server 60e. Similarly, the operation listener terminal TR does not necessarily have to transmit the changed acoustic processing parameter Pa to the audio device 30 via the server 60e.

[0094] Note that the server 60e does not necessarily have to be a distribution server.

[0095] Note that the distributor terminal 10 may be connected to an audio device other than the audio device 30.

[0096] Note that the number of connections between the distributor terminal 10 and the listener terminal 20 is not limited to the examples shown in FIGS. 1 and 4. The distributor terminal 10 may be connected to one or two listener terminals 20. Also, the distributor terminal 10 may be connected to four or more listener terminals 20.

[0097] Note that the distributor terminal 10 and the listener terminal 20 do not necessarily have to be connected by P2P.

[0098] Note that the distributor terminal 10e and the listener terminal 20 may be connected via a plurality of servers in addition to the server 60e.

[0099] Note that the acoustic processing parameter Pa may include values other than the gain value or the mix balance value. The acoustic processing parameter Pa may include, for example, equalizer values, level values, and the like.

[0100] Note that the audio device 30 does not necessarily have to be a mixer.

[0101] Note that the external device 40 does not necessarily have to be a speaker or a microphone.

[0102] Note that the processing unit 105 does not necessarily have to be a CPU. The processing unit 105 may be, for example, an MPU (Micro Processing Unit) or the like.

[0103] Note that in the second embodiment, the operation listener terminal TR may acquire the parameters of the audio device 30 in real time.

[0104] Note that in the second embodiment, the method by which the distributor terminal 10a causes the operation listener terminal TR to display the acoustic processing parameter PaBe is not limited to the method of displaying a text message on the operation listener terminal TR.

[0105] Note that in the third embodiment, the method by which the distributor terminal 10b causes the operation listener terminal TR to display the notification information is not limited to the method of displaying a text message on the operation listener terminal TR.

[0106] Note that, in the fourth embodiment, the method by which the distributor terminal 10c displays the acoustic processing parameter PaAf is not limited to the method of displaying faders and knobs via a GUI. The distributor terminal 10c may display the value of the acoustic processing parameter PaAf, for example, by means of a text message.

[0107] Note that, when changing the acoustic processing parameter Pa, a physical controller may be used. The physical controller includes, for example, faders, knobs, etc. Then, when the operator LL operates the faders, knobs, etc., the acoustic processing parameter Pa is changed. At this time, the operation listener terminal TR and the physical controller are connected, for example, by a cable. In this case, the operation listener terminal TR and the physical controller are connected, for example, via a physical interface (such as USB).
