The detector 26L1 on the left side of the client 20 is connected to the detector 26R2 on the right side of the client adjacent to the left side.

  The client 20 detects whether or not there is an adjacent client using these four detectors 26, and when an adjacent client is detected, acquires the client ID of the adjacent client. The client ID is assigned and set in advance for each client.

  FIG. 9 shows an example of a procedure in which the server 10 shown in FIG. For example, the case of four clients shown in FIG. 4A will be described. The client IDs of the clients A20A to D20D are, for example, “A”, “B”, “C”, and “D”, respectively.

  The client A 20A uses the detector 26 to detect that there is a client with a client ID “B” in the right direction and a client with a client ID “C” in the downward direction. Clients B20B to D20D also detect adjacent clients by their respective detectors 26.

  In the client A 20A, the client ID of its own client is “A”, the client on the right side is the client with the client ID “B”, the client on the lower side is the client with the client ID “C”, Adjacent information indicating that there is no client is transmitted to the server 10. When the server 10 receives the neighbor information from the client A 20A, first, as shown in FIG. 9A, the server 10 registers the client with the client ID “A” on the map for managing the client configuration, and then As shown in FIG. 9B, the client with the client ID “B” is registered on the right side and the client with the client ID “C” is registered on the lower side.

  Next, the client B 20B has its own client ID “B”, the left client is the client ID “A”, the lower client is the client ID “D”, the upper and Adjacent information indicating that there is no client on the right side is transmitted to the server 10. Since the server 10 has already registered the client ID “A” and the client ID “B” on the map, the server 10 does not newly register. Since the client with the client ID “D” is not registered on the map, as shown in FIG. 9C, the client with the client ID “D” is registered below the client with the client ID “B”.

  Further, the client C20C has its own client ID “C”, the upper client is the client ID “A”, the right client is the client ID “D”, and the lower and left clients Transmits adjacent information indicating that there is no client to the server 10. Since all the clients included in the adjacent information are already registered on the map, no new registration is performed. Similarly, the client D20D has its own client ID “D”, the upper client is the client ID “B”, the left client is the client ID “C”, the lower side and Adjacent information indicating that there is no client on the right side is transmitted to the server 10. Since all the clients included in the adjacent information are already registered on the map, no new registration is performed.

  Finally, as shown in FIG. 9D, the server 10 creates a map composed of four clients in two vertical rows and two horizontal rows. The created map is set, that is, stored in the storage unit 11.

  FIG. 10 shows another example of a procedure in which the server 10 shown in FIG. 1 automatically sets the arrangement of the clients 20. In FIG. 9, when the server 10 includes the client ID of the adjacent client in the adjacent information, the server 10 unconditionally registers the adjacent client in the map. However, as illustrated in FIG. The adjacent clients are first temporarily registered, and are distinguished so that they are temporarily registered, for example, like the client with the client ID “C” indicated by the dotted line in FIG. Therefore, when the client is informed that the client is an adjacent client, the client may be registered like the client with the client ID “C” indicated by the thick solid line in FIG.

  9 and 10 show an example of a procedure for automatically setting the arrangement of the client 20 performed by the server 10. Detailed procedures for automatically setting the arrangement of the client 20 will be described later with reference to FIGS.

  FIG. 11 shows an example of the configuration setting screen 40 in the server 10 shown in FIG. The configuration setting screen 40 shown in FIG. 11 is a screen displayed on an output device such as a display (not shown) of the server 10, and is a screen for manually setting the position of each client actually arranged in the server 10. It is. An area 41 for displaying the client to be set is on the right side of the configuration setting screen 40, and the left area is a map area for setting the client to a position corresponding to the position where the client is actually arranged. The case of the configuration of two vertical rows and two horizontal rows shown in FIG. 4A will be described as an example.

  FIG. 11A is a configuration setting screen in which the arrangement position has not yet been set, and the client to be set is displayed in the area 41. The client to be set is a client from which the server 10 has received the adjacent information, and is displayed from the upper side of the area 41 in the order in which the adjacent information is received, for example. The client ID of the first client is “C”, the client ID of the second client is “A”, the client ID of the third client is “B”, and the client ID of the fourth client is “D”.

The user selects a client to be set first using an input device such as a keyboard or a mouse (not shown) of the server 10. At this time, the server 10 instructs the selected client to display that it is selected. For example, if the screen color is changed to a different color from other clients, the client's MAC (Media Access
Control) Instructs address display or display to flush the screen.

  FIG. 11B shows a state in which the first client is set at the position of the map area corresponding to the actual position. The user confirms the actual position of the first client selected in FIG. 11A, that is, the client with the client ID “C”, and sets the client at the position of the map area corresponding to the confirmed position.

  FIG. 12 shows the correspondence with the actual position of the client 20 displayed on the configuration setting screen 40 shown in FIG. FIG. 12A shows a state where the client C20C is selected. When the first client in the area 41 shown in FIG. 11A is selected, the server 10 instructs a display indicating that the client having the client ID “C” is selected, for example, a display for flushing the screen. To do. The client C20C flushes the screen according to an instruction from the server 10.

  FIG. 12B shows a state in which the second client in the area 41, for example, the client A 20A is selected. When the second client in the area 41 shown in FIG. 11A is selected, the server 10 instructs a display indicating that the client with the client ID “A” is selected, for example, a display for flushing the screen. To do. The client A 20A flushes the screen according to an instruction from the server 10.

  FIG. 13 shows an example of manual setting of the second client 20 on the configuration setting screen 40 shown in FIG. The user confirms the position of the flushed client shown in FIG. 12B, and sets the second client, for example, the client A 20A at the position of the map area corresponding to the position. Similarly, settings are made for the third and fourth clients.

  FIG. 14 shows an arrangement position of the client 20 manually set on the configuration setting screen 40 shown in FIG. The client A 20A as the second client is set in the upper left, the client B 20B as the third client is set in the upper right, the client C 20C as the first client is set in the lower left, and the fourth client is set in the lower right. A certain client D20D is set. The map manually set in the map area is stored in the storage device 11.

  In the case where four clients share and display each divided image obtained by dividing the content image, the server 10 enlarges the divided image to be displayed on each client to each client by unicast communication. However, in this case, the amount of data to be transmitted to the client needs to be equal to the number of clients. In order to reduce the amount of data to be transmitted, content is transmitted using multicast communication or broadcast communication.

  Specifically, the server 10 sends the configuration information to each client 20 before transmitting the content, that is, the overall configuration, for example, the number in the vertical direction and the number in the horizontal direction, in the overall configuration. Information indicating the position of each client is transmitted by the server communication unit 13. The configuration information is generated for each client based on the map stored in the storage device 11. For example, in the case of the configuration shown in FIG. 14, the information “configuration is 2 * 2” indicating that the configuration is two vertical rows and two horizontal rows and the position is the first in the second row for the client C20C. Information “Position is 2-1” is generated. Also for other clients, information “configuration is 2 * 2” and information indicating each position are generated.

  Each client 20 recognizes the location of the client in the overall configuration from the received configuration information. Each client determines a divided image at a position corresponding to the recognized arrangement position as a divided image to be displayed by the client. For example, the client A 20A receives information indicating “configuration is 2 * 2” and “position is 1-1” as configuration information. From the received configuration information, the client A 20A knows that its own client is the first client from the left in the first row in the configuration having two rows and two columns. That is, the client A 20A determines that the upper left divided image among the four divided images is the divided image to be displayed by the own client.

  The server 10 transmits the respective pieces of configuration information to all clients, and then transmits the contents by multicast communication or broadcast communication by the server transmission unit 13. Upon receiving the content, each client 20 cuts out a divided image corresponding to the arrangement position of the client from the content image, and enlarges the image according to the screen size. For example, since the client A 20A is the first client from the left in the first stage in the client configuration, the upper left divided image is cut out from the divided images when the received image is divided in half vertically and horizontally, The image is enlarged and displayed two times vertically and horizontally.

  The sound is set so that the server 10 outputs a sound according to the arrangement position of each client. For example, since the arrangement position is the first client from the left in the first row in the client configuration, the client A 20A is set to output the sound of the left channel from the L-SPK 22. Similarly, the client C20C is set to output the sound of the left channel from the L-SPK22. Both the client B 20B and the client D 20D are set to output the sound of the right channel from the R-SPK 23.

  FIG. 15 shows an example of sound allocation to be output from each speaker when the plurality of clients 20 shown in FIG. 1 have a configuration of two vertical rows and two horizontal rows. FIG. 15A shows a configuration in which two clients that output the left channel sound are provided on the left side and two clients that output the right channel sound are provided on the right side. The group CL51 of clients that output the sound of the left channel is configured by the client of the position 1-1 and the client of position 2-1, and the group CR52 of the client that outputs the sound of the right channel is defined as the client of the position 1-2. Configured by the client at location 2-2.

  FIG. 15B1 shows an example in which sound is output using only the outermost speaker. The speaker group SL53 that outputs the sound of the left channel is composed of the clients included in the group CL51, that is, the speaker on the left side of the clients at the position 1-1 and the position 2-1, that is, the L-SPK22, and outputs the sound of the right channel. The speaker group SR54 to be operated is configured by the right speaker of the clients included in the group CR52, that is, the clients at the position 1-2 and the position 2-2, that is, the R-SPK23. Speakers that do not belong to any of the group SL53 and the group SR54, that is, the R-SPK23 of the client at the position 1-1 and the position 2-1, and the L-SPK22 of the client at the position 1-2 and the position 2-2 are , Set mute, ie no sound.

  FIG. 15 (b2) shows an example in which sound is output using speakers other than the outermost speaker. That is, as shown in FIG. 15 (b1), the sound is not output from only the outermost speaker, but the sound is output using another speaker. For example, the speaker group SL53 that outputs the sound of the left channel is configured by the clients included in the group CL51, that is, the L-SPK22 and the R-SPK23 of the client at the position 1-1 and the position 2-1, and the sound of the right channel is formed. Is composed of the clients included in the group CR52, that is, the L-SPK22 and the R-SPK23 of the clients at the position 1-2 and the position 2-2.

  FIG. 16 shows an example of sound allocation to be output from each speaker when the plurality of clients 20 shown in FIG. FIG. 16 (a) shows a configuration in which two clients at the left end output sound of the left channel and two clients at the right end output sound of the right channel. That is, the client group CL51 that outputs the sound of the left channel is configured by the clients of the position 1-1 and the position 2-1, and the group CR52 of clients that output the sound of the right channel is the position 1-3 and the position 2. -3 clients. Clients at positions 1-2 and 2-2 mute both speakers.

  FIG. 16B1 shows an example in which sound is output using only the outermost speaker. The speaker group SL53 that outputs the sound of the left channel is configured by the L-SPK 22 of the client of the position 1-1 and the position 2-1, and the group of speakers SR54 that outputs the sound of the right channel is the position 1-3 and It is configured by the R-SPK 23 of the client at position 2-3. Speakers that do not belong to any of the group SL53 and the group SR54, that is, the R-SPK23 of the client at the position 1-1 and the position 2-1, and the L-SPK22 and R of the client at the position 1-2 and the position 2-2. The SPK 23 and the L-SPK 22 of the client at positions 1-3 and 2-3 are muted.

  FIG. 16B2 shows an example in which sound is output using speakers other than the outermost speaker. That is, as shown in FIG. 16 (b1), the sound is not output only from the outermost speaker, but the sound is output using other speakers. For example, the speaker group SL53 that outputs the sound of the left channel is configured by the L-SPK22 and R-SPK23 of the clients at the positions 1-1 and 2-1, and the speaker group SR54 that outputs the sound of the right channel is formed. , Position 1-3 and position 2-3 are constituted by L-SPK 22 and R-SPK 23 of the client.

  Alternatively, the group SL53 is configured by the L-SPK22 and R-SPK23 of the client at the position 1-1 and the position 2-1, and the L-SPK22 of the client at the position 1-2 and the position 2-2. It may be configured by the R-SPK 23 of the client at 1-2 and the position 2-2, and the L-SPK 22 and R-SPK 23 of the client at the position 1-3 and the position 2-3. In this case, the client located in the middle, that is, the client at the position 1-2 and the position 2-2, outputs the left channel sound from the L-SPK 22, and outputs the right channel sound from the R-SPK 23. As described above, when the number of clients in the horizontal direction is an odd number and sounds are output from all the speakers, the middle client outputs the sound of the left channel from the L-SPK 22 and the sound of the right channel is R-. Output from SPK23.

  FIG. 17 shows an example of sound allocation to be output from each speaker when the plurality of clients 20 shown in FIG. FIG. 17 (a1) shows a configuration in which two clients at the left end output sound of the left channel and two clients at the right end output sound of the right channel. That is, the client group CL51 that outputs the sound of the left channel is configured by the clients of the position 1-1 and the position 2-1, and the group CR52 of the client that outputs the sound of the right channel is the position 1-4 and the position 2. -4 clients. Clients at positions 1-2, 1-3, 2-2, and 2-3 mute all the speakers.

  FIG. 17A2 shows a configuration in which four clients on the left output the sound of the left channel and four clients on the right output the sound of the right channel. That is, the client group CL51 that outputs the sound of the left channel is configured by the clients of the position 1-1, the position 1-2, the position 2-1, and the position 2-2, and the client that outputs the sound of the right channel. The group CR52 is constituted by clients of position 1-3, position 1-4, position 2-3, and position 2-4.

  FIG. 17B1 shows an example in which sound is output using only the outermost speaker. The speaker group SL53 that outputs the sound of the left channel is configured by the L-SPK 22 of the client of the position 1-1 and the position 2-1, and the group of speakers SR54 that outputs the sound of the right channel is the position 1-4 and It is constituted by the R-SPK 23 of the client at position 2-4. Speakers that do not belong to any of group SL53 and group SR54, that is, R-SPK23, position 1-2, position 1-3, position 2-2, and position of clients at positions 1-1 and 2-1. The L-SPK 22 and R-SPK 23 of the 2-3 clients and the L-SPK 22 of the clients of the positions 1-4 and 2-4 are muted.

  FIG. 17B2 shows an example in which sound is output using speakers other than the outermost speaker. That is, as shown in FIG. 17 (b1), the sound is not output from only the outermost speaker, but the sound is output using another speaker. For example, the speaker group SL53 that outputs the sound of the left channel is configured by the L-SPK22 and R-SPK23 of the clients at the positions 1-1 and 2-1, and the speaker group SR54 that outputs the sound of the right channel is formed. And L-SPK 22 and R-SPK 23 of the clients at positions 1-4 and 2-4. The speakers that do not belong to any of the group SL53 and the group SR54, that is, the L-SPK22 and the R-SPK23 of the client at the position 1-2, the position 1-3, the position 2-2, and the position 2-3 are muted. To do.

  FIG. 17B3 shows another example in which sound is output using speakers other than the outermost speaker. That is, the speaker group SL53 that outputs the sound of the left channel is changed into the L-SPK22 and R-SPK23 of the client at the position 1-1 and the position 2-1, and the L-SP of the client at the position 1-2 and the position 2-2. The group SR54 of speakers configured by the SPK22 and outputting the sound of the right channel is divided into the R-SPK23 of the clients at the positions 1-3 and 2-3, and the L-SPK22 of the clients at the positions 1-4 and 2-4. And R-SPK23. Speakers that do not belong to any of the group SL53 and the group SR54, that is, the R-SPK23 of the client at the position 1-2 and the position 2-2, and the L-SPK22 of the client at the position 1-3 and the position 2-3 are , Mute.

  Alternatively, the speaker group SL53 that outputs the sound of the left channel is configured by the L-SPK22 and R-SPK23 of the client at the position 1-1, the position 1-2, the position 2-1, and the position 2-2, and the right The speaker group SR54 that outputs the sound of the channel is configured by the L-SPK22 and the R-SPK23 of the clients at the position 1-3, the position 1-4, the position 2-3, and the position 2-4.

  The number of speakers that output sound is input from an input device (not shown) of the server 10. For example, information indicating the number of speakers from the outside of the speakers arranged in the horizontal direction is input by the input device.

  FIG. 18 is a flowchart of the speaker pattern and volume control processing processed by the server 10 shown in FIG. When there is a content reproduction request from the remote controller of any client 20, and the server 10 receives the content reproduction request from the client 20, the process proceeds to step A1.

  In step A1, the arrangement state of the client is acquired. That is, the adjacent information is acquired from each client, and the entire configuration of the client and the arrangement position of each client are automatically set or manually set based on the acquired adjacent information. The setting contents are stored in the storage unit 11. In step A2, client location information, that is, configuration information representing the overall configuration and the location of each client is transmitted to each client. In step A3, the image division / same size setting is sent to each client. That is, each client transmits information indicating whether to divide and enlarge the received content image or to display the received content image as it is.

  In step A4, a speaker setting process to be described later for setting the number of speakers that output sound is called. In step A5, in accordance with the number of speakers set in the speaker setting process, a sound to be output from a speaker that outputs sound and a sound that is output from the speaker is set, and a speaker setting transmission process to be described later is transmitted to each client. call. In step A6, a content port is designated for each client. That is, a port number indicating a channel to receive content is transmitted to each client.

  In step A7, a setting response is received. That is, a response indicating completion of setting from the client with respect to the information transmitted in step A2, step A3, step A5, and step A6 is received. In step A8, it is determined whether or not responses indicating completion of setting have been received from all clients. If a setting completion response is received from all clients, the process proceeds to step A9. If a setting completion response is not received from all clients, the process returns to step A2. In step A8, the process is repeated until there is a response from all clients. However, if there is no response within a specified time using a timer, an error may be displayed on an output device (not shown) to warn the user. .

  In step A9, content to be transmitted to the client is acquired. For example, it is acquired by reading from the storage unit 11 or acquired from a video output device connected to a network. In step A10, the acquired content is transmitted by multicast or broadcast. In step A11, it is determined whether a speaker change has been received from the client. If a speaker change is received, that is, if a speaker configuration change request is received, the process proceeds to step A13. If a speaker change is not received, that is, if a speaker configuration change request is not received, the process proceeds to step A12. In step A12, it is determined whether or not the content transmission is completed. When the content transmission ends, the process ends. When the content transmission does not end, the process returns to step A10.

  In step A13, a speaker control process, which will be described later, is performed to change the number of speakers that output sound or change the volume output from the speakers. In step A14, the speaker setting is saved, and the process proceeds to step A12. That is, the changed number of speakers or volume is stored in the storage unit 13 so that it can be used next time, and the process proceeds to step A12.

  FIG. 19 is a flowchart of speaker setting processing called from the speaker pattern and volume control processing shown in FIG. In the speaker setting process, the number of speakers that output sound is set. When called at step A4 shown in FIG. 18, the process proceeds to step B1.

  In step B1, it is determined whether or not the environment used last time is used. The environment used last time is the number of speakers used last time, and is stored in the storage unit 11. Whether or not the number of speakers used last time is used is determined by, for example, displaying a menu for inquiring whether or not to use the number of speakers used last time on an output device (not shown), and by a response to the menu by an input device (not shown). to decide. If the previously used environment is used, the process proceeds to step B4. If the previously used environment is not used, the process proceeds to step B2.

  In step B2, the number of speakers SP to be output is manually set. For example, the number of speakers is input by an input device (not shown). The number of speakers SP is divided into one when the speakers of each client arranged vertically and horizontally are divided into vertical groups consisting of speakers in one vertical column, and the divided vertical groups are divided into two at the center in the horizontal direction. This is the number of vertical groups that output sound among the vertical groups to which they belong. The vertical group that outputs sound is a vertical group closer to the outside in the horizontal direction. That is, sound is output from the left group of vertical group speakers corresponding to the number of speakers SP, and from the right end of the vertical group speakers corresponding to the number of speakers SP. In step B3, the speaker setting is saved. That is, the input number of speakers is stored in the storage unit 11 and the process is terminated.

  In step B4, it is determined whether there is a setting storage. That is, when the number of speakers is stored in the storage unit 13, it is determined that there is a setting storage. If there is setting storage, the process proceeds to step B5, and if there is no setting storage, the process proceeds to step B6. In step B5, the previously set number of speakers SP is used. That is, the number of speakers to be used is set to the number of speakers stored in the storage unit 13 as it is, and the process ends. In step B6, a default number of speakers, for example, SP = 1 is used. That is, the number of speakers to be used is set to a default number of speakers, for example, “1”, and the process is terminated.

  FIG. 20 is a flowchart of the first half of speaker control processing called from the speaker pattern and volume control processing shown in FIG. The speaker control process changes the number of speakers that output sound or changes the volume output from the speakers. When called at step A13 shown in FIG. 18, the process proceeds to step C1.

  In step C1, the arrangement state of the client is acquired. That is, the adjacent information is acquired from each client, and the entire configuration of the client and the arrangement position of each client are automatically set or manually set based on the acquired adjacent information. Hereinafter, the client is also referred to as a “monitor”. In step C2, the number of effective monitors in the horizontal direction SPM is acquired. That is, the number of monitors in the horizontal direction is extracted from the overall configuration set in step C1, and the number of extracted monitors is set as the number of horizontal monitors in the effective monitor SPM.

  In step C3, it is determined whether to increase the number of speakers. That is, if there is a request to increase the number of speakers in the request to change the speaker configuration received from the client in step A11 in FIG. 18, it is determined that the number of speakers is to be increased. If the number of speakers is to be increased, the process proceeds to step C5. If the number of speakers is not increased, the process proceeds to step C4. In step C4, it is determined whether or not the number of speakers is reduced. That is, if there is a request to reduce the number of speakers in the request to change the speaker configuration received from the client in step A11 in FIG. 18, it is determined that the number of speakers is to be reduced. If the number of speakers is to be reduced, the process proceeds to step C8. If the number of speakers is not to be decreased, the process proceeds to step C11 shown in FIG.

  In step C5, it is determined whether SP <SPM. That is, it is determined whether or not the number of speakers SP that outputs sound is smaller than the number of effective monitors SPM in the horizontal direction. If SP <SPM, that is, if the number of speakers SP is smaller than the lateral number SPM, the process proceeds to step C6. If SP <SPM is not satisfied, that is, if the number of speakers SP is not smaller than the lateral number SPM, the process ends. . In step C6, “SP = SP + 1” is set. That is, the number of speakers SP is increased by “1”. In step C7, a speaker setting transmission process to be described later is called, and when the speaker setting transmission process ends, the process proceeds to step C11 shown in FIG. The speaker setting transmission process determines the sound to be output from the speaker that outputs sound and the sound that is output from the speaker according to the number of speakers, and transmits the determined content to each client.

  In step C8, it is determined whether SP> 1. That is, it is determined whether or not the number of speakers SP that outputs sound is greater than “1”. If SP> 1, that is, if the number of speakers SP that outputs sound is larger than “1”, the process proceeds to step C9. If SP> 1 is not true, that is, the number of speakers SP that outputs sound is “1”. If it is not too large, the process ends. In step C9, "SP = SP-1" is set. That is, the number of speakers SP is decreased by “1”. In step C10, a speaker setting transmission process described later is called, and when the speaker setting transmission process ends, the process proceeds to step C11 shown in FIG.

  FIG. 21 is a flowchart of the latter half of the speaker control process called from the speaker pattern and volume control process shown in FIG. When it is determined in step C4 shown in FIG. 20 that the number of speakers is not reduced, or after step C7 or step C10 is processed, the process proceeds to step C11.

  In step C11, it is determined whether or not the speaker volume control is performed. That is, if there is speaker volume control in the request for changing the speaker configuration received from the client in step A11 in FIG. 18, it is determined that the speaker volume control is being performed. If it is speaker volume control, it will progress to step C12, and if it is not speaker volume control, it will be complete | finished.

  In Step C12, “VOL = set volume / SP” is set. That is, a value obtained by dividing the set volume, that is, the already set volume by the number of speakers SP is set as the unit volume VOL. In Step C13, “NV = 1” is set. That is, the initial value “1” is substituted into the counter NV. In step C14, the NV-th speaker from the end is set to a volume of “set volume-VOL * (NV-1)”. For example, the volume of “set volume” is set for the farthest speaker, the volume of “set volume−VOL” is set for the second speaker from the end, and the “set volume” is set for the third speaker from the end. -2VOL "volume is set. That is, the volume decreases by 1 VOL in order from the end.

  In step C15, the setting is sent to the corresponding client. That is, the volume set in step C14 is transmitted to a client having a speaker that outputs a sound of that volume. In Step C16, “NV = NV + 1” is set. That is, “1” is added to the counter NV. In step C17, it is determined whether NV <= SP. That is, it is determined whether or not the value of the counter NV is equal to or less than the number of speakers SP. If NV <= SP, that is, if the value of the counter NV is equal to or less than the number of speakers, the process returns to step C14. If NV <= SP, that is, if the value of the counter NV exceeds the number of speakers, the process ends.

  In the example shown in FIG. 21, an example in which the sound output is controlled in the horizontal direction according to the arrangement position of the client is shown, but the sound output may be controlled in the vertical direction. Specifically, the volume of the upper client may be increased and the volume of the lower client may be decreased.

  FIG. 22 is a flowchart of speaker setting transmission processing called from the speaker pattern and volume control processing shown in FIG. In the speaker setting transmission process, the sound output speaker and the sound to be output from the speaker that outputs the sound are determined according to the number of speakers set in the speaker setting process shown in FIG. 19, and the determined content is transmitted to each client. . The speaker setting transmission process is also called from the speaker control process shown in FIG. When called at step A5 shown in FIG. 18, step C7 shown in FIG. 20, or step C10 shown in FIG. 20, the process proceeds to step D1.

  In step D1, “SP2 = INT (SP / 2)” is set. That is, the integer part of the value obtained by dividing the number of speakers SP by 2 is the number SP2 of monitors that output sound from the left and right speakers. In step D2, the SP2 speakers are enabled from the left monitor, and the Lch output is set for both L / R. That is, the left and right speakers of the two SP monitors are enabled from the left side of the monitor arranged in the horizontal direction, and the sound to be output is set to output Lch, that is, the left channel sound for both L-SPK22 and R-SPK23. . In step D3, the SP2 speakers are validated among the monitors arranged on the right, and the Rch output is set for both L / R. That is, the left and right speakers of the two SP monitors are enabled from the right side of the monitor arranged in the horizontal direction, and the sound to be output is set so that both L-SPK22 and R-SPK23 output Rch, that is, the right channel sound. .

  In step D4, it is determined whether or not “SP = odd number”. That is, it is determined whether or not the number of speakers is an odd number. If “SP = odd number”, that is, if the number of speakers is an odd number, the process proceeds to step D7, and if “SP = odd number”, that is, if the number of speakers is not an odd number, the process proceeds to step D5. In step D5, the ineffective speaker is set to mute. That is, the speaker that has not been enabled in step D2, step D3, step D7, or step D8 is set not to output sound. In step D6, the setting is sent to the corresponding monitor and the process ends. That is, the setting of each speaker is transmitted to the monitor having the respective speaker, and the process ends.

  In step D7, only the monitor L of “SP2 + 1” is validated from the left monitor, and the Lch output is set. That is, the L-SPK 22 of the “SP2 + 1” -th monitor from the left side of the monitor arranged in the horizontal direction is validated and set to output Lch, that is, the sound of the left channel. In Step D8, only the R of the monitor “SP2 + 1” is validated from the right monitor, Rch output is set, and the process proceeds to Step D5. That is, the R-SPK 23 of the “SP2 + 1” -th monitor from the right side of the monitor arranged in the horizontal direction is validated and set to output Rch, that is, the sound of the right channel, and the process proceeds to step D5.

  This speaker setting transmission process is set so that the left channel sound is output from the speakers corresponding to the number SP of speakers from the left end in the horizontal direction, and the right channel sound is output from the speakers corresponding to the number SP of speakers from the right end in the horizontal direction. The

  In the example shown in FIG. 22, in step D5, the speaker that has not been enabled is set to mute, that is, the sound is not output, but the speaker that has not been enabled is used instead of the bass subwoofer. You may be more realistic. Specifically, for example, only the bass part of the left and right channel sounds are respectively extracted and amplified, and the left channel bass part is output from the speaker arranged on the left side among the mute-set speakers, The bass part of the channel is controlled to output from the speaker arranged on the right side among the speakers set to mute.

  FIG. 23 is a flowchart of the speaker pattern and volume control processing processed by the client 20 shown in FIG. When the configuration information is received from the server 10, the process proceeds to step E1.

  In step E1, client location information, that is, configuration information representing the overall configuration and the location of each client is acquired. In step E2, the image division / same size setting is received. In other words, the server 10 receives information from the server 10 that indicates image division / same size setting, that is, whether to divide and enlarge the content image, or to display the received content image as it is. In step E3, it is determined whether or not multi-playback is performed. If it is multi-reproduction, that is, if the information received from the server 10 is image division setting, the process proceeds to step E4. If it is not multi-reproduction, the process proceeds to step E12.

  In step E4, screen division / enlargement is set. That is, the divided image corresponding to the arrangement position of the client is set to be enlarged among the divided images obtained by dividing the content image. In step E5, speaker setting is performed. That is, the speaker setting transmitted in the speaker setting transmission process of the server 10 shown in FIG. 22 is received, and the received speaker setting is set for the speaker of the own client. In step E6, a content acquisition port is set. That is, it receives and sets the speaker pattern of the server 10 and the port number transmitted in the volume control process shown in FIG. In step E7, a setting completion notification is performed. That is, a response indicating that the setting has been completed is transmitted to the server 10.

  In step E8, the playback content is received and played back. That is, the content transmitted from the server 10 is received, and the received content is reproduced and displayed on the display screen unit 25. In step E9, it is determined whether or not a speaker change interrupt has occurred. That is, when a speaker configuration change is requested by an interrupt by the input unit 27, for example, a remote controller, it is determined that a speaker change interrupt has occurred. If there is a speaker change interrupt, the process proceeds to step E13. If there is no speaker change interrupt, the process proceeds to step E10. In step E10, it is determined whether a speaker change has been received. That is, when the changed speaker setting is received from the server 10, it is determined that the speaker change has been received. If the speaker change is received, the process proceeds to step E14. If the speaker change is not received, the process proceeds to step E11. In step E11, it is determined whether or not the content has ended. When the content ends, the process ends. When the content does not end, the process returns to step E8.

  In step E12, the same size screen is set and the process proceeds to step E5. That is, the screen is set to be displayed at the same magnification without dividing / enlarging the screen, and the process proceeds to Step E5. In step E13, a change request is transmitted to the server, and the process proceeds to step E10. That is, a request for changing the configuration of the speaker is received from the remote controller, for example, a request for increasing the speaker, a request for reducing the speaker, or a request for controlling the volume of the speaker is received, and the received request for changing the configuration is transmitted to the server. In step E14, speaker setting is performed, and the process proceeds to step E11. That is, the speaker setting transmitted from the server 10 is received, the received speaker setting is performed, and the process proceeds to Step E11.

  FIG. 24 is a flowchart of the position setting process processed by the server 10 shown in FIG. The position setting process is a process for setting the arrangement position, and when called in the process of step A1 shown in FIG. 18 or the process of step C1 shown in FIG. 20, the process proceeds to step F1.

  In step F1, it is determined whether or not to use the previous setting. That is, for example, when an input device (not shown) instructs to use the previously used client configuration stored in the storage unit 11, it determines that the previous setting is used. If the previous setting is used, the process proceeds to step F5. If the previous setting is not used, the process proceeds to step F2. In step F2, it is determined whether or not automatic setting is performed. That is, for example, if there is an instruction to automatically set the configuration of the client by an input device (not shown), it is determined that the automatic setting is performed. If automatic setting is to be performed, the process proceeds to step F7. If automatic setting is not to be performed, the process proceeds to step F3.

  In step F3, the configuration is manually set. For example, the client configuration is set on the configuration setting screen 40 shown in FIG. In step F4, the current setting is saved and the process ends. That is, the setting of the client configuration newly set in step F3 is stored in the storage unit 11, and the process is terminated. In step F5, it is determined whether there is a set value. That is, if the setting of the client configuration is stored in the storage unit 11, it is determined that there is a setting value. If there is a set value, the process proceeds to step F6, and if there is no set value, the process proceeds to step F2. In step F6, the previously stored set value is used and the process ends. That is, the setting of the client configuration is set as it is, and the processing ends.

  In step F7, an automatic setting process described later for automatically setting the monitor configuration is called. In step F8, an effective block selection process (to be described later) for selecting a group of monitors for displaying content is called. The effective block is a block for displaying content among blocks constituted by adjacent clients. In step F9, the current setting is saved and the process ends. That is, the setting of the client configuration newly set in step F7 and step F8 is stored in the storage unit 11, and the process ends.

  FIG. 25 shows an example of a reception array and a piece array used by the server 10 shown in FIG. In the figure, “piece” is also referred to as “Piece”. FIG. 25A shows a monitor state and a reception array corresponding to the monitor state. The monitor state indicates the actual configuration of the monitor. The reception arrangement is an arrangement in which adjacent information received from each monitor by the server 10 is arranged, for example, in the order of responses from the monitors, and is stored in the storage unit 11 of the server 10. The reception array includes items of “own ID” indicating the client ID of each monitor, and “upper”, “left”, and “upper” indicating the client IDs of the monitors adjacent to the upper, left, lower, and right sides of each monitor, respectively. There are items of "Bottom" and "Right". Hereinafter, the client IDs shown in the “upper”, “left”, “lower”, and “right” item columns are referred to as adjacent monitor IDs.

  The monitor shown in FIG. 25A is composed of nine monitors in three rows and three rows. Three monitors with client IDs “B”, “D”, and “F” from the left are arranged in the upper row, and client IDs “C”, “E”, and “G” from the left are arranged in the middle row. ”And three monitors with client IDs“ A ”,“ H ”, and“ I ”from the left are arranged in the lower row.

  For example, for a monitor having its own ID “C”, the “up” adjacent monitor ID is “B” and the “left” adjacent monitor ID is “NULL”. The “lower” adjacent monitor ID is “A”, and the “right” adjacent monitor ID is “E”. “NULL” indicates that there is no adjacent monitor. Similarly, for the self ID “E”, “D”, “C”, “H”, and “G” and the self ID “ “I” is “G”, “H”, “NULL”, and “NULL”, and the self ID is “D” with “NULL”, “B”, “E”, and “F”. Yes, when the self ID is “G”, “F”, “E”, “I”, and “NULL”, and when the self ID is “A”, “C”, “NULL”, “NULL” , And “H”, and the self ID “F” is “NULL”, “D”, “G”, and “NULL”, and the self ID “B” is “NULL”, “ NULL], “C”, and “D”, and the self ID is “H”, “E”, “A”, “N” LL], and is the "I".

  FIG. 25 (b) shows a piece array. The piece array is a two-dimensional array of received adjacent information items and “check” items indicating the arrangement confirmation status in the order of piece numbers indicating the order in which responses are received. The piece array has six items for each piece number: “own ID”, “upper ID”, “left ID”, “lower ID”, “right ID”, and “check”. Of these six items, the items other than “check” correspond to the five items in the receiving array shown in FIG. The item “check” indicates the state of confirmation of arrangement, and values “0” to “2” are entered. “0” indicates that the arrangement has been confirmed, “1” indicates an initial value, that is, no confirmation has been performed, and “2” indicates that the arrangement has been confirmed. Is in a state where it is adjacent to a monitor that has not been confirmed yet.

  Each element of the piece array is represented by piece [m] [n]. [M] is a piece number. [N] is a number corresponding to six items of “own ID”, “upper ID”, “left ID”, “lower ID”, “right ID”, and “check”. It is a number assigned an integer from "." That is, "Own ID" is [0], "Upper ID" is [1], "Left ID" is [2], "Lower ID" is [3], "Right ID" is [4], and "Check" Is [5]. The contents of the reception array shown in FIG. 25A are directly entered in piece [0] [0] to piece [8] [4].

  FIG. 26 shows an example of the confirmed ID storage array used by the server 10 shown in FIG. The confirmed ID storage array sumi [] is an array for registering the client ID of the monitor whose arrangement has been confirmed, and is stored in the storage unit 11. In the figure, “sumi” is also referred to as “Sumi”. The monitor registered in the confirmed ID storage array is a monitor in which the check column of the piece array is “0”, and the client ID of the monitor, that is, “own ID” is registered in the confirmed ID storage array. The confirmed ID storage array shown in FIG. 26 is initialized and all are blank, that is, “NULL”.

  FIG. 27 shows an example of the end ID storage array used by the server 10 shown in FIG. The end ID storage array haji [] is an array for registering client IDs of monitors without a monitor adjacent to the left side and the upper side, and is stored in the storage unit 11. In the figure, “haji” is also referred to as “Haj”. The end ID storage array shown in FIG. 27A is initialized and all are blank, that is, a state of “NULL”. The end ID storage array shown in FIG. 27B shows a state after the end ID search process described later is performed, and the monitor with the client ID “B” is registered. “Haji_count” indicates the number of monitors without a monitor adjacent to the left side and the upper side, that is, the number of monitors registered in the end ID storage array, and is registered in haji [0] to haji [haji_count-1].

  FIG. 28 is a flowchart of the automatic setting process called from the position setting process shown in FIG. The automatic setting process automatically sets the monitor configuration. When called in step F7 shown in FIG. 24, the process moves to step G1.

  In step G1, a configuration acquisition / storage process (to be described later) for storing adjacent information received from each client in a piece array is called. In step G2, a later-described confirmed ID storage array securing process for initializing the confirmed ID storage array is called. In step G3, an end ID storage array securing process (to be described later) for initializing the end ID storage array is called. In step G4, an end ID search process, which will be described later, for searching for a monitor without a monitor adjacent to the left and upper sides is called.

  In step G5, “block = 0”, “chk_total = 0”, and “BB = 0” are set. That is, the counter block for counting the number of blocks constituted by adjacent clients, the number of confirmed monitors chk_total, and the end ID confirmation counter BB are cleared to “0”. In the figure, “block” is also referred to as “Block”, and “chk_total” is also referred to as “Chk_total”. In step G6, it is determined whether or not piece [] [5] ≠ 0 in the piece array having the ID of haji [BB]. That is, it is determined whether the value of the check item piece [] [5] in the piece array of the client ID of the client ID of the BB-th monitor in the end ID storage array haji [] is “0”, that is, whether or not it has been confirmed. If piece [] [5] ≠ 0, that is, if it has not been confirmed, the process proceeds to step G7, and if piece [] [5] ≠ 0, that is, if piece [] [5] = 0, the monitor has already been executed. Has already been set, the process proceeds to step G11.

  In step G7, a map storage process, which will be described later, is performed for determining blocks configured by adjacent clients and creating a map of the monitor that configures each block. In step G8, “chk_total = chk_total + count + 1” is set. That is, the count value counted in the map storing process in step G7 and “1” are added to the number of confirmed monitors chk_total. In step G9, it is determined whether chk_total <total. If the confirmed number chk_total of the monitors is smaller than the total number of monitors, the process proceeds to step G10. If the confirmed number of monitors chk_total is not smaller than the total number of monitors, the process ends. In step G10, “block = block + 1” is set. That is, “1” is added to the block, and another block is confirmed. In step G11, “BB = BB + 1” is set, and the process returns to step G6. That is, "1" is added to the end ID confirmation counter BB, and the process returns to step G6 to confirm the next monitor not adjacent to the left side and the upper side.

  FIG. 29 is a flowchart of the configuration acquisition / storage process called from the automatic setting process shown in FIG. In the configuration acquisition / storage process, a piece array is created to determine the total number of monitors. In the figure, “total” is also referred to as “Total”. When called in step G1 shown in FIG. 28, the process proceeds to step H1.

  In step H1, “total = 0” is set and piece [] is secured / cleared. That is, first, the total number of monitors is cleared to “0”, a storage area for storing the piece array is secured in the storage unit 11, and the storage area is cleared to NULL. In step H2, an ID request is transmitted to the client through the control port. That is, the client of each client is connected to each client via the control port 33 of the network, for example, the control channel 33 of “IP = xx.xx.xx.xx: Port = xx” shown in FIG. A transmission request for adjacent information including the ID and the detected adjacent client is transmitted.

  In step H3, it is determined whether there is a response from the client, that is, a response of adjacent information. If there is a response from the client, the process proceeds to step H4, and if there is no response from the client, the process proceeds to step H6. In Step H4, “piece [total] [0] = reception ID” is set, “reception neighbor information is stored in piece [total] [4] from“ piece [total] [0] ”, and“ piece [total] [5] ] = 1 ”. That is, the client ID of the client that transmitted the neighbor information included in the neighbor information is registered in the “own ID” of the total piece array, and the “upper ID”, “left ID”, and “bottom” of the total piece array are registered. "ID" and "Right ID" include the client ID of the client adjacent on the upper side, the client ID of the client adjacent on the left side, the client ID of the client adjacent on the lower side, and the client ID of the client adjacent on the right side. Register the client ID. When there is no adjacent client, “NULL” indicating that there is no adjacent client is registered. The initial value “1” is registered in “check” of the total piece array.

  In step H5, “total = total + 1” is set, and the number of monitors responding to total is increased by “1”. That is, “1” is added to the total number of monitors. In step H6, it is determined whether it is within the timeout. That is, it is determined whether or not a monitoring time for monitoring a response to the ID request transmitted in step H2, for example, 10 seconds has not elapsed. If it is within the timeout, that is, within the monitoring time, the process returns to step H3, and if it is not within the timeout, that is, within the monitoring time, the process is terminated.

  FIG. 30 is a flowchart of the confirmed ID storage array securing process called from the automatic setting process shown in FIG. When called in step G2 shown in FIG. 28, the process proceeds to step J1. In step J1, sumi [] is secured / cleared and the process ends. That is, a storage area for storing the confirmed ID storage array sumi [] is secured in the storage unit 11, the storage area is cleared to NULL, and the process ends.

  FIG. 31 is a flowchart of the end ID storage array securing process called from the automatic setting process shown in FIG. When called in step G3 shown in FIG. 28, the process proceeds to step K1. In step K1, haji [] is secured / cleared and the process ends. That is, a storage area for storing the end ID storage array haji [] is secured in the storage unit 11, the storage area is cleared to NULL, and the process ends.

  FIG. 32 is a flowchart of an end ID search process called from the automatic setting process shown in FIG. When called in step G4 shown in FIG. 28, the process proceeds to step L1. In step L1, “haji_count = 0” is set. That is, first, the number haji_count of monitors having no monitor adjacent to the left side and the upper side is cleared to “0”. In step L2, “c = 0” is set. That is, the piece number “c” of the array to be checked in the piece array is cleared to “0”. In the figure, “c” is also referred to as “C”.

  In step L3, it is determined whether or not piece [c] [1] = NULL & piece [c] [2] = NULL. That is, it is determined whether or not the monitor of the array to be checked is a monitor without a monitor adjacent to the left side and the upper side. If piece [c] [1] = NULL & piece [c] [2] = NULL, that is, if the monitor of the array to be checked is a monitor without a monitor adjacent to the left side and the upper side, the process proceeds to step L6, and piece [ If c] [1] = 0 & piece [c] [2] = 0, that is, if the monitor of the array to be checked is a monitor with a monitor adjacent to the left side or the upper side, the process proceeds to step L4. In step L4, “c = c + 1” is set. That is, “1” is added to the piece number “c” of the array to be checked in the piece array. In step L5, it is determined whether c <total. That is, it is determined whether or not the value of the piece number “c” of the array to be checked in the piece array is smaller than the total number of monitors. If c <total, that is, if the value of the piece number “c” of the array to be checked in the piece array is smaller than the total number of monitors, the process returns to step L3. If c <total is not satisfied, that is, the piece array. If the value of the piece number “c” of the array to be checked is not smaller than the total number of monitors, the process ends.

  In step L6, “haji [haji_count] = piece [c] [0]”. That is, the client ID of the monitor without the adjacent monitor on the left side and the upper side is registered in the haji_countth of the end ID storage array. In step L6, “haji_count = haji_count + 1” is set, and the process proceeds to step L4. That is, “1” is added to the number haji_count of monitors without a monitor adjacent to the left side and the upper side, and the process proceeds to Step L4.

  FIG. 33 is a flowchart of the first half of the map storage process called from the automatic setting process shown in FIG. In the map storage process, a block constituted by adjacent clients is determined and a map of a monitor constituting each block is created. When called in step G7 shown in FIG. 28, the process proceeds to step M1.

  In step M1, “count = 0, MM = 100, NN = 100, cc = 0” is set. A counter count for counting the number of monitors in the block is cleared to “0”, and the maximum number of monitors in the vertical direction and the maximum number of monitors in the horizontal direction of the block are set. In this example, the maximum number is “100” in all cases, but it is not limited to this value. Further, the counter cc for confirming whether or not the monitor has returned to the first monitor is cleared to “0”.

  In step M2, “mat [block] [0] [0] to mat [block] [254] [254] = NULL, temp = 0” is set. That is, each element of the three-dimensional array Mat representing the map for each block is initialized to “NULL”, and temp is cleared to “0”. In the figure, “mat” is also referred to as “Mat”, and “temp” is also referred to as “Temp”. “block” is a counter for counting the number of blocks, and the initial value is “0”. In streaming, IDs that can be flowed in the same segment are “0” to “254”. In this example, the range of the second and third elements of the mat array is “0” to “254”. However, the present invention is not limited to this.

In step M3, “next confirmation ID = haji [ BB ]” is set. That is, the client ID of the monitor to be confirmed next is the confirmed ID registered at the array position indicated by the value of “ BB ” in the end ID storage array haji []. In other words, among the monitors registered in the end ID storage array as monitors without an adjacent monitor on the left side and the upper side, the client ID registered at the array position indicated by the value “ BB ” is used.

  In step M4, “current ID = next confirmation ID, next confirmation ID = NULL”. That is, the client ID of the monitor for confirming whether there is a current ID, that is, whether there is an adjacent monitor, is the client ID indicated by “next confirmation ID”, and then initializes “next confirmation ID” to “NULL”. To do. In step M5, “sumi [count]” = current ID, and the current ID's piece [] [5] = 0 ”. That is, the client ID indicated by the current ID is registered in the confirmed ID storage array sumi [], and the check item of the piece array of the client ID indicated by the current ID is set to “0”, that is, confirmed.

  In step M6, “M = MM, N = NN”. That is, the value of the pointer M indicating the vertical position of the map is set as the value of MM, and the value of the pointer N indicating the horizontal position of the map is set as the value of NN. In step M7, an array including the current ID is extracted from piece [0] [0] to piece [total-1] [0]. In step M8, “mat [block] [M] [N] = piece of current ID piece [] [0]” is set. In other words, the vertical Mth and horizontal Nth positions of the map are set as client IDs indicated by the current ID.

  In step M9, an upper adjacent process described later for checking whether there is an adjacent monitor on the upper side is called. In step M10, a left adjacency process to be described later for checking whether there is an adjacent monitor on the left side is called. In step M11, a lower adjacent process to be described later for checking whether there is an adjacent monitor on the lower side is called. In step M12, a right adjacent process described later for checking whether there is an adjacent monitor on the right side is called. In Step M13, it is determined whether or not “next confirmation ID” = NULL. If the “next confirmation ID” is NULL, that is, if the monitor to be confirmed next is not in the adjacent monitor, the process proceeds to step M20 shown in FIG. 34, and if the “next confirmation ID” is not NULL, that is, If the monitor to be checked next is in the adjacent monitor, the process proceeds to step M14. In step M14, “count = count + 1” is set, and the process returns to step M4. That is, “1” is added to the counter count for counting the number of monitors in the block, and the process returns to step M4.

  FIG. 34 is a flowchart of the latter half of the map storage process called from the automatic setting process shown in FIG. If it is determined in step M13 illustrated in FIG. 33 that the “next confirmation ID” is NULL, the process proceeds to step M20.

  In step M20, “cc = count” is set. That is, the counter cc for confirming whether or not the first monitor has been returned is set to the value of the counter count for counting the number of monitors in the block. In step M21, “cc = cc−1” is set. That is, “1” is subtracted from the counter cc for confirming whether or not the monitor has returned to the first monitor. Step M22 determines whether or not cc <0. If cc <0, that is, return to the first monitor, the process ends. If not cc <0, that is, if the first monitor is not returned, the process proceeds to step M23.

  In step M23, it is determined whether or not the piece [] [1] = NULL of the sumi [cc] ID. That is, it is determined whether or not the upper ID in the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [1] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the upper side, the process proceeds to step M27, and the piece [] [1] = NULL of the sumi [cc] ID. If there is no adjacent monitor on the upper side, the process proceeds to step M24.

  In step M24, it is determined whether or not the piece [] [2] = NULL of the sumi [cc] ID. That is, it is determined whether or not the left ID of the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [2] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the left side, the process proceeds to step M28, and the piece [] [2] = NULL of the sumi [cc] ID. If there is no adjacent monitor on the left side, the process proceeds to step M25.

  In step M25, it is determined whether or not the piece [] [3] = NULL of the sumi [cc] ID. That is, it is determined whether or not the ID below the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [3] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the lower side, the process proceeds to step M29, and the piece [] [3] = NULL of the sumi [cc] ID. If there is, that is, if there is no adjacent monitor on the lower side, the process proceeds to step M26.

  In step M26, it is determined whether or not piece [] [4] = NULL of the sumi [cc] ID. That is, it is determined whether or not the right ID in the piece array of the client ID registered in sumi [cc] is NULL among the client IDs registered in the confirmed ID storage array sumi []. When the piece [] [4] of the sumi [cc] ID is not NULL, that is, when there is an adjacent monitor on the right side, the process proceeds to Step M30, and the piece [] [4] = NULL of the sumi [cc] ID. If there is no adjacent monitor on the right side, the process returns to step M21.

  In Step M27, “next confirmation ID = piece [] [1] having an ID of sumi [cc]” is set, and the process proceeds to Step M31. That is, “next confirmation ID” is set as the client ID of the upper ID in the piece array of the client ID registered in sumi [cc], and the process proceeds to step M31. In step M28, “next confirmation ID = piece [] [2] having ID of sumi [cc]” is set, and the process proceeds to step M31. That is, “next confirmation ID” is set as the client ID of the left ID of the piece array of the client ID registered in sumi [cc], and the process proceeds to step M31. In step M29, “next confirmation ID = piece [] [3] having ID of sumi [cc]” is set, and the process proceeds to step M31. That is, “next confirmation ID” is set as the client ID of the lower ID of the client ID registered in sumi [cc], and the process proceeds to step M31. In Step M30, “next confirmation ID = piece [] [4] having ID of sumi [cc]” is set, and the process proceeds to Step M31. That is, “next confirmation ID” is set as the client ID of the right ID in the piece array of the client ID registered in sumi [cc], and the process proceeds to step M31.

  In step M31, a search is made for mat [block] [M] [] and mat [block] [] [N] of mat [block] having “next confirmation ID”. That is, the vertical position M and the horizontal position N where the “next confirmation ID” is located are searched from the block including the client ID indicated by the “next confirmation ID”. In Step M32, “MM = M, NN = N” is set, and the process returns to Step M14 shown in FIG. That is, the value of MM is the value of M, and the value of NN is the value of N. That is, MM and NN are set to values representing positions in the monitor map to be checked next, that is, the values of M and N found in step M31, and the process returns to step M14 shown in FIG.

  FIG. 35 is a flowchart of the upper adjacent process called from the map storage process shown in FIG. The upper adjacent process confirms whether there is an adjacent monitor on the upper side. When called at step M9 shown in FIG. 33, the process proceeds to step N1.

  In step N1, it is determined whether or not the current ID piece [] [1] is not NULL. If the current ID piece [] [1] is not NULL, that is, if there is a client ID in the ID above the current ID piece array, the process proceeds to step N2, and if the current ID piece [] [1] is NULL, That is, the process ends when the upper ID of the current ID piece array is NULL.

  In Step N2, it is determined whether or not the client ID of the current ID piece [] [1] is in piece [0] [0] to piece [total-1] [0]. That is, it is determined whether or not the client ID indicated by the upper ID of the current ID piece array is within the own ID of the piece array. When the client ID of the current ID piece [] [1] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the upper ID of the current ID piece array is piece. If it is in the own ID of the array, the process proceeds to step N3, where the client ID of the current ID piece [] [1] is not in piece [0] [0] -piece [total-1] [0], that is, If the client ID indicated by the upper ID in the piece array of the current ID is not in the own ID of the piece array, the process ends.

  In Step N3, it is determined whether or not the target piece [] [5] is not “0”. That is, it is determined whether or not the check item of the piece array of the client ID indicated by the upper ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the upper ID has not been confirmed, the process proceeds to Step N4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the upper ID has been confirmed, the process ends.

  In step N4, it is determined whether mat [block] [M-1] [N] is not NULL. That is, it is determined whether or not a client ID is set at a position on the map. If mat [block] [M-1] [N] is not NULL, that is, if the client ID is set at one position on the map, the process proceeds to Step N7, where mat [block] [M-1] If [N] is NULL, that is, if the client ID is not set at the position one higher on the map, the process proceeds to Step N5. In Step N5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the upper ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step N6, the current ID piece [] [1] is set in mat [block] [M-1] [N]. That is, the client ID of the upper ID of the current ID piece array is set at a position one level higher on the map.

  In Step N7, “next confirmation ID = piece of current ID piece [] [1]” is set. That is, the “next confirmation ID” is set as the client ID of the upper ID in the piece array of the current ID. In step N8, piece [] [1] having the current ID is set to NULL. That is, the upper ID of the current ID piece array is set to NULL, and the search has been completed. In step N9, piece [] [3] having the target ID is set to NULL. In other words, the lower ID of the piece array of “next confirmation ID” is set to NULL, and the search has been completed. In Step N10, “MM = M−1, NN = N” is set, and the process ends. That is, MM and NN are set to values representing the position in the monitor map to be checked next, that is, the position one level higher, and the process ends.

When the client ID of the current ID piece [] [2] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the left ID of the current ID piece array is the piece ID. If it is in the own ID of the array, the process proceeds to Step P3, and if the client ID of the current ID piece [] [2] is not in piece [0] [0] to piece [total-1] [0], that is, If the client ID indicated by the left ID in the piece array of the current ID is not in the own ID of the piece array, the process ends.

  In Step P3, it is determined whether or not the target piece [] [5] is not “0”. That is, it is determined whether or not the check item of the piece array of the client ID indicated by the left ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the left ID has not been confirmed, the process proceeds to Step P4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the left ID has been confirmed, the process ends.

  In step P4, it is determined whether mat [block] [M] [N-1] is not NULL. That is, it is determined whether or not the client ID is set to the left one position on the map.

In Step P5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the left ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step P6, the current ID piece [] [2] is set in mat [block] [M] [N-1]. That is, the client ID of the left ID of the piece array of the current ID is set to the left one position on the map.

  In Step P7, it is determined whether or not “next confirmation ID” is set. If “next confirmation ID” is set, the process ends. If “next confirmation ID” is not set, the process proceeds to step P8. That is, in the upper adjacent process shown in FIG. 33, when “next confirmation ID” has already been set, updating of “next confirmation ID” is skipped.

  In step P8, “next confirmation ID = piece of current ID piece [] [2]” is set. That is, the “next confirmation ID” is set as the client ID of the left ID in the piece array of the current ID. In step P9, piece [] [2] having the current ID is set to NULL. That is, the left ID of the current ID piece array is set to NULL, and the search is completed. In step P10, piece [] [4] having the target ID is set to NULL. That is, the right ID of the piece array of “next confirmation ID” is set to NULL, and the search is completed. In Step P11, “MM = M, NN = N−1” is set, and the process ends. That is, MM and NN are set to values representing the position in the monitor map to be checked next, that is, the position one place to the left, and the process ends.

That is, it is determined whether or not the client ID indicated by the lower ID of the current ID piece array is within the own ID of the piece array. If the client ID of the current ID piece [] [3] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the lower ID of the current ID piece array is the piece ID. If it is in the own ID of the array, the process proceeds to step Q3, and the client ID of the current ID piece [] [3] is not in piece [0] [0] to piece [total-1] [0], that is, If the client ID indicated by the lower ID of the current ID piece array is not within the own ID of the piece array, the processing ends.

That is, it is determined whether or not the check item of the piece array of the client ID indicated by the lower ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the lower ID has not been confirmed, the process proceeds to step Q4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the lower ID has been confirmed, the process ends.

  In step Q4, it is determined whether mat [block] [M + 1] [N] is not NULL. That is, it is determined whether or not the client ID is set at the next lower position on the map. If mat [block] [M + 1] [N] is not NULL, that is, if the client ID is set at the next lower position on the map, the process proceeds to step Q7, where mat [block] [M + 1] [N] If it is NULL, that is, if the client ID is not set at the next lower position on the map, the process proceeds to step Q5. In Step Q5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the lower ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step Q6, the current ID piece [] [3] is set in mat [block] [M + 1] [N]. That is, the client ID of the lower ID in the piece array of the current ID is set at the position one level lower on the map.

  In step Q7, it is determined whether or not “next confirmation ID” is set. If “next confirmation ID” is set, the process ends. If “next confirmation ID” is not set, the process proceeds to step Q8. That is, when “next confirmation ID” is already set in the upper adjacent process shown in FIG. 35 or the left adjacent process shown in FIG. 36, the update of “next confirmation ID” is skipped.

  In step Q8, “next confirmation ID = piece of current ID piece [] [3]”. That is, the “next confirmation ID” is set as the client ID of the lower ID of the current ID piece array. In step Q9, piece [] [3] having the current ID is set to NULL. That is, the lower ID of the current ID piece array is set to NULL, and the search is completed. In step Q10, piece [] [1] having the target ID is set to NULL. That is, the upper ID of the piece array of “next confirmation ID” is set to NULL, and the search has been completed. In step Q11, the process ends with “MM = M + 1, NN = N”. In other words, MM and NN are set to values representing the position in the monitor map to be checked next, that is, the position one level below, and the process ends.

  FIG. 38 is a flowchart of the right adjacent process called from the map storage process shown in FIG. The right adjacency process checks whether there is an adjacent monitor on the right side. When called in step M12 shown in FIG. 33, the process proceeds to step R1.

  In step R1, it is determined whether or not the current ID piece [] [4] is not NULL. If the current ID piece [] [4] is not NULL, that is, if there is a client ID in the right ID of the current ID piece array, the process proceeds to step R2, and if the current ID piece [] [4] is NULL, That is, the processing ends when the right ID of the current ID piece array is NULL.

  In step R2, it is determined whether or not the client ID of the current ID piece [] [4] is in piece [0] [0] -piece [total-1] [0]. That is, it is determined whether or not the client ID indicated by the right ID of the current ID piece array is in the own ID of the piece array. If the client ID of the current ID piece [] [4] is in piece [0] [0] to piece [total-1] [0], that is, the client ID indicated by the right ID of the current ID piece array is piece. If it is in the own ID of the array, the process proceeds to step R3, where the client ID of the current ID piece [] [4] is not in piece [0] [0] -piece [total-1] [0], that is, If the client ID indicated by the right ID in the piece array of the current ID is not in the own ID of the piece array, the processing ends.

  In Step R3, it is determined whether or not the target piece [] [5] is not “0”. That is, it is determined whether or not the check item of the piece array of the client ID indicated by the right ID is “0”. If the target piece [] [5] is not “0”, that is, if the check item of the piece array of the client ID indicated by the right ID has not been confirmed, the process proceeds to step R4, and the target piece [] [5] is “0”. ", That is, if the check item of the piece array of the client ID indicated by the right ID has been confirmed, the process ends.

  In step R4, it is determined whether mat [block] [M] [N + 1] is not NULL. That is, it is determined whether or not the client ID is set to the right one position on the map. If mat [block] [M] [N + 1] is not NULL, that is, if the client ID is set to the right one position on the map, the process proceeds to step Q7, where mat [block] [M] [N + 1] If it is NULL, that is, if the client ID is not set to the right one position on the map, the process proceeds to step Q5. In Step Q5, “target piece [] [5] = 2” is set. That is, the check item of the piece array of the client ID indicated by the right ID is set to “2”. “2” indicates that it is adjacent to a monitor whose arrangement has been confirmed and has not yet been confirmed. In step R6, the current ID piece [] [4] is set in mat [block] [M] [N + 1]. That is, the client ID of the right ID in the piece array of the current ID is set to the right one position on the map.

  In step R7, it is determined whether or not “next confirmation ID” is set. If “next confirmation ID” is set, the process ends. If “next confirmation ID” is not set, the process proceeds to step R8. That is, when the “next confirmation ID” is already set in the upper adjacent process shown in FIG. 35, the left adjacent process shown in FIG. 36, or the lower adjacent process shown in FIG. The update of “next confirmation ID” is skipped.

  In step R8, “next confirmation ID = piece of current ID piece [] [4]”. That is, “next confirmation ID” is set as the client ID of the right ID in the piece array of the current ID. In step R9, piece [] [4] having the current ID is set to NULL. That is, the right ID of the current ID piece array is set to NULL, and the search is completed. In step R10, piece [] [2] having the target ID is set to NULL. That is, the left ID of the piece array of “next confirmation ID” is set to NULL, and the search is completed. In Step R11, “MM = M, NN = N + 1” is set, and the process ends. That is, MM and NN are set to values indicating the position in the monitor map to be checked next, that is, the position to the right of one, and the process ends.

  FIG. 39 is a flowchart of an effective block selection process called from the position setting process shown in FIG. In the effective block selection process, a block for displaying content is selected. When called in step F8 shown in FIG. 24, the process proceeds to step S1.

  In step S1, it is determined whether or not Block> 0. That is, it is determined whether or not the number of blocks is larger than “0”. If Block> 0, that is, if the number of blocks is larger than “0”, the block is divided into two or more blocks, so that the process proceeds to step S4. If Block> 0 is not satisfied, that is, the number of blocks is “0”. If not, the process proceeds to step S2. In step S2, block = 0 is validated. In other words, block = 0 indicates that there is no block. In step S3, it is determined whether or not the selected block is configured as a square. That is, it is determined whether or not the shape of the selected and effective block, that is, the shape formed by the monitor screen that forms the block is a quadrangle. If the selected block is configured as a square, that is, if the shape of the selected block is a square, the process ends. If the selected block is not configured as a square, that is, if the selected block is not a square, the process proceeds to step S6. When the shape of the selected block is a quadrangle, the client ID of the monitor included in the block is stored in the storage unit 11.

  In step S4, a block is selected. That is, one block for displaying content is selected from a plurality of blocks. For example, the blocks are selected by assigning a block number to a plurality of blocks in the monitor configuration automatically set in the automatic setting process in step F7 shown in FIG. This is selected by specifying a block number with an input device (not shown) of the server 10. In step S5, the selected block is validated and the process proceeds to step S3. In step S6, the effective range is selected and the process ends. For example, the monitor is selected so that the shape of the selected monitor screen forms a quadrangle, and the process ends. The monitor selection may be selected, for example, by specifying a client ID with an input device (not shown) of the server 10 or may be selected by instructing a monitor set on the configuration setting screen 40. The selected block number and the client ID of the selected monitor are stored in the storage unit 11. The server 10 transmits the content to the selected monitor among the monitors constituting the block indicated by the block number stored in the storage unit 11.

  Thus, for example, the client 20 which is a plurality of display units each having a speaker, for example, which is a sound output unit which displays an image on the screen and converts sound signals such as sound signals into sound and outputs them, is determined in advance. Sound information arranged at each position and output by each sound output unit of a plurality of display units is selected from a plurality of predetermined sound information according to the arrangement position of each display unit, and each selected sound information is displayed Since the sound is output by the sound output unit, the sound corresponding to the position of the screen of each display unit in the large screen configured by the plurality of display units can be output from each display unit. Therefore, when displaying one content video on a large screen, it is possible to obtain an audio multiplexed sound effect over the plurality of display units.

  Further, for example, the client 20 which is a plurality of display units displays each of the divided images of the plurality of divided images obtained by dividing one image in an enlarged size of the screen, and each display unit Since one image constituted by the divided images to be displayed is displayed so as to coincide with the enlarged image of the one image before being divided, it is displayed on a large screen by a plurality of display units having a multi-screen configuration. A sound corresponding to the position of the image displayed by each display unit in one image can be output from each display unit. Therefore, a realistic sound can be output.

  Furthermore, for example, a speaker that is a sound output unit is a left-side sound output unit that is provided on the left side of the screen, for example, the portion of the client 20 that is a display unit having the sound output unit, such as L-SPK22. And R-SPK23 which is a right sound output unit provided on the right side of the screen, and the selected sound information is output by the left sound output unit and the right sound output unit of each display unit. Even if the display unit has left and right sound output units, the same sound according to the arrangement position can be output from the left and right sound output units. Therefore, each display unit can output the left channel sound from the left sound output unit and the right channel sound from the right sound output unit to distinguish between the left channel sound and the right channel sound. It can be prevented that it becomes impossible.

  Furthermore, for any two adjacent display units of the clients 20, for example, the plurality of display units, the sound output unit of the display unit closer to the center of the arrangement formed by the screens of the plurality of display units. For example, since the volume of a speaker is output at a volume smaller than the volume of the sound output section of the display section far from the center, the display section arranged at a position far from the center can be output at a larger volume. Therefore, a more realistic sound can be output.

  Furthermore, the plurality of predetermined sound information includes, for example, a sound signal that is stereo left channel sound information and right channel sound information, and is formed by each screen of the client 20 that is the plurality of display units. The left channel sound information is output by the sound output unit of at least one of the display units arranged on the left side of the screen with respect to the center of the arrangement, and the display is arranged on the right side of the screen. Since the sound information of the right channel is output by the sound output unit of at least one display unit among the units, the stereo effect can be exhibited in the plurality of display units each having the sound output unit. Therefore, a more realistic sound can be output.

  Furthermore, the sound output method of the display system 1 that is a display device also includes a plurality of, for example, speakers that are sound output units that display images on a screen and convert sound signals such as sound signals into sound and output them. For example, the client 20 which is a display unit is arranged at a predetermined arrangement position, and sound information to be output by each sound output unit of the plurality of display units is set to the arrangement position of each display unit from among the plurality of predetermined sound information. Since the selected sound information is output by the sound output unit of each display unit, the sound corresponding to the position of the screen of each display unit in the large screen composed of the plurality of display units is displayed. Part can output. Therefore, when displaying one content video on a large screen, it is possible to obtain an audio multiplexed sound effect over the plurality of display units.
