[0006] Patent Document 1: Japanese Patent Application Laid-Open No. 2002-199474 Summary of the invention

[0007] Technical issues

[0008] In the above-described system, a technology capable of controlling reproduction of content by a plurality of reproduction apparatuses connected to a network with good operability is desired.

[0009] In view of the above circumstances, an object of the present technology is to provide an information processing device, an information processing method, and a program capable of controlling reproduction of content by a plurality of reproduction devices connected to a network with good operability.

[0010] Solution to the problem

[0011] In order to achieve the above-mentioned object, an information processing device according to an embodiment of the present technology includes a detection unit, an acceptance unit, and an image control unit.

[0012] The detection unit can respectively detect whether each of a plurality of reproduction devices, each of which is connected to the network and can reproduce the content, constitutes a group related to the reproduction of the content.

[0013] The receiving unit receives an operation from a user regarding formation of a group.

[0014] The image control unit outputs a group status image based on the detection result of the detection unit, and controls the group status image in response to the accepted operation related to the composition of the group, wherein the group status image represents the composition status of the group, and the group status image includes an image showing each of the multiple reproduction devices.

[0015] In the information processing device, it is detected whether each of a plurality of reproduction devices connected to a network constitutes a group. A group status image including an image of each of the plurality of reproduction devices is output based on the detection result, and the group status image is controlled in response to a user operation. Therefore, the user can control the reproduction of content with good operability while viewing the group status image.

[0016] When a reproducing device constituting a group is detected, the image control unit may display an image of the group including the reproducing device in the group status image.

[0017] Therefore, it is possible to easily know whether a group is currently established.

[0018] The group may be a group that can simultaneously reproduce the same content.

[0019] By using the present technology, it is possible to control simultaneous reproduction of content by a group with good operability.

[0020] The accepting unit may accept a first operation of selecting an image showing the reproduction device. In this case, the image control unit may emphatically display an image showing the reproduction devices that can constitute the group in response to the first operation.

[0021] Therefore, it is possible to easily know the devices that can constitute a group, and to perform the establishment of a group and the like with good operability.

[0022] The accepting unit may accept a second operation that causes an image showing a non-constituent device that can constitute the group to be moved in the group state image in a condition where an image showing a non-constituent device that is a reproduction device that does not constitute the group is selected. In this case, when the destination of the second operation is an image showing a reproduction device that can constitute the group, the image control unit may display an image showing a group reconstructed by the selected non-constituent device and the reproduction device as the destination.

[0023] Therefore, a group can be established with a simple operation.

[0024] When the destination of the second operation is an image showing an already created group, the image control unit may display an image showing a group newly constituted by the selected non-constituent device and the reproducing device included in the group as the destination.

[0025] Therefore, non-configuration devices can be added to the group with a simple operation.

[0026] When the destination of the second operation is a position where an image of another reproducing device is not shown, the image control unit may cause the image showing the selected non-constituent device to move to the position.

[0027] Therefore, the playback device can be moved in the group status image by simple operation.

[0028] When the destination of the second operation is an image showing a reproducing device that cannot constitute a group, the image control unit may return the selected image showing the non-constituting device to its original position.

[0029] Therefore, it is possible to easily know that a group cannot be created or the like, and operability is improved.

[0030] The accepting unit may accept a third operation that causes the image showing the group devices, which are the reproduction devices constituting the group, to move in the group state image in a state where the image showing the group devices is selected. In this case, when the destination of the third operation is a position away from the image showing the group including the selected group device, the image control unit displays an image in which the group devices are withdrawn from the group.

[0031] Therefore, the group device can be withdrawn from the group by a simple operation.

[0032] The image control unit can identifiably display one of the plurality of group devices included in the group as a main device, and when an image showing the main device is selected and moved to a position away from an image showing the group by a third operation, display an image in which the group is disbanded.

[0033] Therefore, the group can be disbanded with a simple operation.

[0034] The accepting unit may accept a fourth operation of selecting an image of the group. In this case, the image control unit may output a reproduction information image including information related to reproduction of content by a plurality of group devices included in the group in response to the fourth operation.

[0035] Therefore, it is possible to perform reproduction settings and the like for each group with a simple operation.

[0036] The reproduction information image may include information of contents that the plurality of group devices can simultaneously reproduce.

[0037] Therefore, it is easy to know the content that can be reproduced for each group.

[0038] The image control unit may display meta information related to content being reproduced by the plurality of group devices in the group status image.

[0039] Therefore, information on the content can be known.

[0040] The receiving unit may be a touch panel. In this case, the group status image may be displayed on the touch panel.

[0041] The reproduction of content can be controlled with good operability by using the touch panel.

[0042] An information processing method according to an embodiment of the present technology includes respectively detecting whether each of a plurality of reproduction devices, each of which is connected to a network and is capable of reproducing content, constitutes a group related to reproduction of content.

[0043] An operation from a user regarding formation of the group is accepted.

[0044] A group status image is controlled based on a detection result by a detection unit, and the group status image is controlled in response to an accepted operation related to the composition of the group, wherein the group status image represents the composition status of the group and includes an image showing each of the plurality of reproduction devices.

[0045] The program according to the embodiment of the present technology causes a computer to execute the following steps:

[0046] respectively detecting whether each of a plurality of reproduction devices constitutes a group related to reproduction of content, each of the plurality of reproduction devices being connected to a network and each of the plurality of reproduction devices being capable of reproducing the content;

[0047] accepting operations from users related to the formation of groups; and

[0048] A group status image is output based on a detection result by a detection unit, and the group status image is controlled in response to an accepted operation related to the composition of the group, wherein the group status image represents the composition status of the group and includes an image showing each of the plurality of reproduction devices.

[0070] Hereinafter, embodiments according to the present technology will be described with reference to the drawings.

[0071] [Network system]

[0072] Figure 1 The network system 500 includes a home network 1 created in a house, a plurality of reproduction devices 10 connected thereto, a server device 20 providing content, and a portable terminal 30 serving as an information processing device according to the present embodiment.

[0073] As the home network 1, for example, a network conforming to the DLNA (Digital Living Network Alliance) standard is used. In this case, each of the plurality of reproduction devices 10 serves as a DMR (Digital Media Renderer), and the server device 20 serves as a DMS (Digital Media Server). In addition, the portable terminal 30 serves as a DMC (Digital Media Controller). However, this configuration is not limited thereto, and for example, a network utilizing another protocol may also be used.

[0074] The plurality of reproduction devices 10, server device 20 and portable terminal 30 are connected to the home network 1 via an access point (not shown) by wireless communication such as WiFi, for example. However, the method of connecting to the home network 1 is not limited, and wired communication via a LAN cable or the like may be used.

[0075] like Figure 1As shown, the plurality of reproduction devices 10 are placed in the rooms of a living room 2, a hobby room 3, and a bedroom 4. By operating a portable terminal 30, a user 5 can instruct the respective reproduction devices 10 placed in the rooms to reproduce content in a server device 20. In this embodiment, music content is reproduced by the plurality of reproduction devices 10. However, the present technology is not limited to the reproduction of music content, and can be applied to the reproduction of various contents such as videos. Note that the number of reproduction devices 10 is not limited.

[0076] As each reproduction device 10, a reproduction device that can operate as a DMP (Digital Media Player) can be placed. In this case, by operating the UI (User Interface) of each reproduction device 10, the content can be reproduced in the server device 20.

[0077] As each reproduction device 10, for example, a television receiver, a PC (personal computer), an audio video receiver, a video monitor, a home video game console, etc. are used. As the server device 20, for example, a PC, a network-ready HDD (NAS), etc. are used. As the portable terminal 30, a smartphone is generally used. However, it is not limited to this, and it may also be a PDA (personal digital assistant) such as a tablet terminal and a game console.

[0078] Note that in this embodiment, a reproduction device 13 not connected to the home network 1 (hereinafter referred to as a non-network device) is placed Figure 1 The non-network device 13 does not function as a DMR, and reproduces a CD, content read via a USB (Universal Serial Bus), or content acquired from another global network, etc. In this embodiment, the operation of the non-network device 13 can be controlled by the portable terminal 30 through near field communication such as Bluetooth (registered trademark).

[0079] [Configuration of portable terminal]

[0080] Figure 2 3 is a block diagram showing a configuration example of a portable terminal 30. The portable terminal 30 includes a CPU (Central Processing Unit) 31, a ROM (Read Only Memory) 32, a RAM (Random Access Memory) 33, a display 34, and a touch panel 35. In addition, the portable terminal 30 includes a communication unit 36, an external I / F (Interface) 37, a key / switch 38, and an imaging unit 39.

[0081] The CPU 31 exchanges signals with various blocks of the portable terminal 30 to perform various operations, and centrally controls various processes performed in the portable terminal 30 such as instructions for the reproducing device 10 to reproduce content and display images on the display 34 (touch panel 35 ).

[0082] The ROM 32 stores various data such as various image data and metadata, and various programs such as applications, which are processed by the CPU 31. The RAM 32 is used as a work area for the CPU 31. When a program such as an application is executed, various data required for the execution is loaded into the RAM 32.

[0083] An HDD (Hard Disk Drive), a flash memory, or another nonvolatile memory such as a solid-state memory may be provided instead of or in addition to the ROM 32. Then, in these storage devices, the above-mentioned various data or programs may be stored.

[0084] The display 34 is a display device using liquid crystal, EL (electroluminescence), or the like. Figure 2 As shown, the display 34 is formed integrally with the touch panel 35. Therefore, various GUIs (Graphical User Interfaces) are displayed on the touch panel 35, and touch operations can be input with respect to the GUI. In this embodiment, the touch panel 35 serves as an acceptance unit.

[0085] The communication unit 36 ​​is an interface for connecting the portable terminal 30 to the home network 1 or the non-network device 13. For example, as the communication unit 36, a wireless LAN module such as WiFi or a short-range wireless module such as Bluetooth (registered trademark) is provided.

[0086] The external I / F 37 is an interface for connecting to an external device based on standards such as USB and HDMI (registered trademark) (High-Definition Multimedia Interface). In addition, an interface for connecting to various memory cards such as a memory stick may be configured.

[0087] The key switch unit 38 specifically accepts operations performed by the user 5 which cannot be input via the touch panel 35 such as a power switch and shortcut keys. The imaging unit 39 includes, for example, a CMOS (Complementary Metal Oxide Semiconductor) or CCD (Charge Coupled Device) sensor, and generates a digital image of a subject.

[0088] The information processing performed by the portable terminal 30 having the above-mentioned hardware configuration is realized by the cooperation of the software stored in the ROM 32 and the like and the hardware resources of the portable terminal 30. For example, by the CPU 31 loading the program (application) according to the present technology stored in the ROM 32 and the like into the RAM 33 to execute it, the information processing method according to the present technology is realized. Figure 2 As shown, the CPU 31 functions as a detection unit 40, an image control unit 41, and a group control unit 42. To realize these blocks, dedicated hardware may be used appropriately.

[0089] A program such as an application is installed in the portable terminal 30 from, for example, a global network. Alternatively, the program may be installed in the portable terminal 30 via a recording medium.

[0090] [Multi-room reproduction]

[0091] As an operation of the portable terminal 30 according to the present embodiment, multi-room reproduction of content will be described. Multi-room reproduction is a reproduction method in which a group is composed of two or more reproduction devices 10 connected to the home network 1, and the group reproduces the same content simultaneously.

[0092] For example, by having multiple reproduction devices 10 in the same room reproduce the same content, music can be enjoyed at a high volume throughout the room. Or, for example, in the case of inviting many friends and having a party, the party can be livened up by having the reproduction devices 10 placed in the room reproduce the same content and controlling the operations simultaneously.

[0093] In the present embodiment, one of two or more reproduction devices 10 constituting a group is set as a master device, and the other reproduction devices 10 are set as slave devices. When performing multi-room reproduction, an instruction is sent to the master device. The master device downloads content from the server device 20, and simultaneously performs streaming distribution on the slave device. Thus, multi-room reproduction of content is achieved. Note that the method of achieving multi-room reproduction is not limited, and any technology related to, for example, synchronous reproduction can be appropriately used.

[0094] In the present technology, as described later, the current configuration state of the group is displayed transparently on the touch panel 35 of the portable terminal 30. Then, based on the image, it is possible to re-establish the group, disband the group, add a new member to the group, or withdraw from the group with good operability. Therefore, it is possible to control the multi-room reproduction of the content with good operability.

[0095] Figure 3 1 is a sequence diagram showing an operation example when a group status image showing a configuration status of a group is output. Figure 3 In FIG. 1 , three reproduction devices A to C are shown as reproduction devices connected to the home network 1 in order to simplify the diagram.

[0096] When the application is activated by the user 5, the detection unit 40 of the portable terminal 30 generates a search request for finding the reproduction device 10, and transmits the search request on the home network 1 by broadcasting (step 101). The reproduction devices A to C each transmit a response to the search request to the portable terminal 30 (step 102). The response includes information indicating whether it is a multi-room ready device.

[0097] A multi-room ready device is a reproduction device 10 that can form a group and perform multi-room reproduction. A reproduction device 10 that cannot perform multi-room reproduction is a not-ready device. Specifically, in step 102, information on whether a group can be formed is sent to the portable terminal 30.

[0098] The detection unit 40 makes an inquiry about the group status to the multi-room ready devices (reproduction devices A to C in this example) (step 103). The group status is information indicating whether it constitutes a group, or if it constitutes a group, whether it is a master device or a slave device.

[0099] By using the search request in step 101 and the inquiry about the group status in step 103, the detection unit 40 of the portable terminal 30 can detect whether each of the plurality of reproduction devices 10 connected to the home network 1 and capable of reproducing content constitutes a group for multi-room reproduction. Note that a control message such as UPnP (Universal Plug and Play) or the like for this detection is transmitted on the home network 1. It goes without saying that it is not limited to this, and another arbitrary technique may be used to perform the detection.

[0100] The detection unit 40 makes an inquiry to the master device (reproduction device A in this example) about checking the list of group devices (in step 104). The group devices are the reproduction devices 10 constituting the group. The master device sends a list of slave devices belonging to the group in response to the inquiry (step 105).

[0101] The detection unit 40 can determine the current group configuration state based on the acquired information. The image control unit 41 outputs a group state image based on the determination result. Note that a unique ID is set for each reproduction device, so the reproduction device can be identified.

[0102] Figure 4 and Figure 5 Each is a diagram showing a configuration example of a group status image 50 displayed on the touch panel 35 . Figure 3 A group status image 50A is shown in which no group is created, and Figure 4 A group status image 50B is shown in which a group is created.

[0103] like Figure 4 and Figure 5 As shown, the group status image 50 includes icon images 51 of a plurality of reproduction devices 10 connected to the home network 1. On the icon image 51, respective images depending on the kind of the reproduction device are displayed. Figure 4 and Figure 5 The icon images 51a to 51d shown correspond to Figure 1 The reproduction devices 10a to 10d are shown.

[0104] For example, each icon image 51 includes a text image 52 indicating a name. Therefore, it is possible to know the correspondence with the actual reproduction device 10 placed in each room. In addition, on each icon image 51, a network mark 53 (a WiFi mark in this example) indicating the connection form with the portable terminal 30 and a separate communication mark 54 (a Bluetooth (registered trademark) mark in this example) are placed. The network mark 53 is actively displayed on the reproduction device 10 connected to the home network 1.

[0105] The group status image 50 includes an icon image 55 of the non-network device 13 that is not connected to the home network 1. In addition, on the icon image 55, a text image 52, a network mark 53, and a separate communication mark 54 are placed. The separate communication mark 54 is actively displayed on the non-network device 13. Alternatively, information indicating that it is a non-network device 13 may be displayed.

[0106] For example, by selecting the plus sign 59 or the like in the group status image 50, detection of the non-network device 13 is performed, and its icon image 55 is displayed if it is detected. The detection of the non-network device 13 may be automatically performed.

[0107] In this embodiment, the reproduction devices 10 and 13 in the surrounding environment can be collectively displayed on the touch panel 35. Therefore, the reproduction of the content can be controlled with good operability. Note that the non-network device 13 cannot perform multi-room reproduction.

[0108] like Figure 5 As shown, in the case where a group has been created, that is, in the case where a group device is detected, a group image 56 of the group including the group devices is displayed. The group image 56 is a circular image, and the icon images 51 of the group devices belonging to the group are displayed on the periphery of the group image 56. Figure 5 In the example shown, Figure 1 The reproduction devices 10 b and 10 d shown are detected as group devices, and its icon images 51 b and 51 e are placed on the periphery of the group image 56 .

[0109] When the group image 56 is displayed, the icon image 51 (the icon image 51e in this example) of the reproduction device 10 as the master device is displayed emphatically so that the master device can be identified. The method of emphasizing the icon image 51 is not limited, and the text image 52 is mainly displayed, for example, as shown in FIG. Figure 5 It goes without saying that it is not limited to this, and any display method such as emphasizing the color of the icon image 51 and blinking the icon image 51 may be adopted. Note that information indicating that it is a master device may be newly added.

[0110] like Figure 5As shown, display of the network mark 54 or the like of the icon image 51 placed on the periphery of the group image 56 may be omitted because it is obviously connected to the home network 1. Note that in the case where a plurality of groups are created, a plurality of group images 56 corresponding to the groups are displayed.

[0111] The method and technique of generating the group status image 50 is not limited, and any method and technique may be used. Figure 3 In steps 102, 103, etc. in the above, device information including the above-mentioned information related to the group composition and information for generating the group status image 50 is obtained. The device information may include an icon image of each reproduction device 10, and the icon image 51 may be used. Information about the name and the like is extracted from the device information, and a text image 52 is generated based on the information.

[0112] Alternatively, the icon image 51 is stored on the portable terminal 30 side, and an optimal icon image 51 may be selected based on the acquired device information. Alternatively, information or images such as the icon image 51 for generating the group status image 50 may be acquired via a global network such as the Internet.

[0113] The design of the icon image 51 or the group image 56 and the layout of the group status image 50 are not limited to Figure 4 , Figure 5 etc., and can be set appropriately.

[0114] The user 5 can input various operations related to the formation of the group to the group state image 50 displayed on the touch panel 35. The image control unit 41 controls the group state image 50 in response to the operations received by the touch panel 35.

[0115] For example, when inputting operations such as re-establishing a group or adding a new member, Figure 2 The group control unit 42 shown sends a request or instruction for a dependent operation to the master device. The master device responds to the request or the like operation and returns the result to the group control unit 42. The image control unit 41 controls the group status image 50 based on the information.

[0116] The detection unit 40 may make an inquiry about the group status at a predetermined timing (a timing after the master device is operated, etc.) or periodically. Then, based on the inquiry result, the group status image 50 may be controlled.

[0117] [Highlights of multi-room ready devices]

[0118] Figure 6is a diagram showing a configuration example of the group status image 50C in the case where a first operation is input. The first operation is an operation in which the icon image 51 of the reproduction device 10 in the group status image 50C is selected by the user 5. In response to the first operation, the image control unit 41 emphatically displays the icon images 51 of the reproduction devices 10 that can constitute a group among the icon images 51 in the group status image 50C (in this example, the icon 51b, the icon 51c, and the icon 51e). Specifically, the multi-room ready devices are emphatically displayed.

[0119] The method of emphasizing the icon image 51 is not limited. In the present embodiment, when the user 5 selects the icon image 51, an animation that dynamically changes the size of the icon image 51 of the multi-room ready device is displayed. Specifically, the icon image 51 of the multi-room ready device is enlarged or reduced. Alternatively, an animation whose color changes over time or an animation in which the icon image flashes may be displayed. Hereinafter, in some cases, the animation is simply referred to as an image.

[0120] By emphasizing the icon image 51 of the multi-room ready device, it is possible to easily know the multi-room ready device and perform the establishment of a group, etc. with good operability. Note that in this embodiment, even in the case where any one of the icon images 51 in the group status image 50C is selected, the icon image 51 of the multi-room ready device is emphatically displayed. Alternatively, the emphasizing display of the icon image 51 of the multi-room ready device may be performed only in the case where the icon image 51 of the multi-room ready device is selected. Furthermore, in the case where the icon image 55 of the non-network device 13 is selected, an indication thereof may be displayed.

[0121] [New creation of group]

[0122] Figure 7 5 is a diagram showing a configuration example of a group status image 50D in the case of inputting new creation of a group. When re-establishing a group, the user 5 inputs a second operation. The second operation is an operation of moving the icon image 51 in the group status image 50 while selecting the icon image 51 (in this example, the icon image 51b) of the reproduction device 10 that is a multi-room ready device and does not constitute a group (hereinafter, referred to as a non-constituting device).

[0123] like Figure 7 As shown, in the case where the destination of the second operation is the icon image 51e of the multi-room ready device and the selection is released on the icon image 51e, the selected non-constituent device and the multi-room ready device as the destination re-constitue the group, and the group image 56 thereof is displayed. As a result, the image changes from Figure 7 The group status image 50D shown transitions to the group status image 50B.

[0124] At this time, for example, an image in which two images of the icon image 51b and the icon image 51e are separated from each other by a predetermined distance, an image in which the circular shape of the group image 56 is expanded from a dotted line shape to a predetermined size, an image in which a color is added to the group image 56, etc. are displayed. Therefore, it is possible to easily recognize that a group is created. As described above, a group can be easily established by simply dragging and dropping an icon image 51 of a non-constituent device capable of performing multi-room reproduction onto an icon image 51 of another multi-room ready device.

[0125] Note that the image control unit 41 can automatically adjust the position or size of each image so that the icon image 51 and the group image 56 do not overlap each other. For example, in the case of displaying a plurality of group images 56, the size of the circular shape of each group image 56 is appropriately reduced and displayed. Therefore, the group constituent image 50 can be simply displayed.

[0126] Figure 8 201 is a sequence diagram showing an example of the operation of re-establishing a group. The group control unit 42 acquires the network status of the reproduction devices A to C as the target of group formation (step 201). The network status is information indicating the connection status with the home network 1, such as information on the network strength. This process can be performed at the input of the re-establishment Figure 7 The operations of the groups shown are performed from time to time or periodically.

[0127] Based on the acquired information about the network status, any one of the multi-room ready devices is set as the master device (step 202). For example, the reproduction device 10 with higher network strength is set as the master device. The method of determining the master device is not limited, and the user can select the master device.

[0128] The group control unit 42 sends a group establishment request to the master device (reproduction device A in this example) (step 203). The request includes the IDs of the reproduction devices (reproduction devices B and C in this example) that are slave devices. The master device that receives the establishment request sends a request to participate in the group to the reproduction devices B and C that are slave devices (step 204). Thus, a group is created, and the reproduction devices A to C are in a group state (step 205).

[0129] Note that Figure 8 In the example shown, there are multiple reproduction devices as slave devices. Figure 7 In the case of the operation shown in FIG. 1 , any one of the reproduction devices 10 b and 10 e is set as the master device, and a group participation request is sent to the other reproduction device 10. In the case where the touch panel 35 supports multi-touch operations performed by multiple fingers, two non-constituent devices are moved to another multi-room ready device in some cases. In this case, as shown in FIG. Figure 8As shown, a participation request is sent to the plurality of reproduction devices.

[0130] [New additions to groups]

[0131] Fig. 9 and Fig.10 50E and 50F are diagrams showing configuration examples of group status images 50E and 50F in a case where an operation of new addition to a group is input. Fig. 9 As shown in FIG. 5 , in the case where the destination of the second operation is the group image 56 of the already created group, the selected non-constituent device and the group device included in the group as the destination constitute the group again. Fig.10 As shown, a group image 56' is displayed as an image representing a group. An icon image 51c of a selected non-constituent device and icon images 51b and 51e of group devices included in the group are placed on the periphery of the group image 56'.

[0132] At this time, the animation may be appropriately displayed with respect to the position of each icon image 51 and the size or color of the circular shape of the group image 56 ′. As described above, by simply dragging and dropping a multi-room-ready non-constituent device onto the group image 56 , a new addition to the group can be easily made.

[0133] Fig.11 301 is a sequence diagram showing an example of the operation of new addition to a group. The group control unit 42 sends a request to add a slave device to the master device (reproduction device A in this example) (step 301). The master device sends a request to participate in the group to the reproduction device to be added (reproduction device C in this example) based on the ID included in the addition request (step 302). As a result, reproduction device C is added to the group as a slave device (step 303).

[0134] [Move icon image]

[0135] When the destination of the second operation is a position where there is no icon image 51 of another reproduction device in the group state image 50, the image control unit 42 moves the selected icon image 51 to that position. Therefore, the icon image 51 can be moved with a simple operation and the positional relationship between the icon images 51 can be changed.

[0136] For example, it is possible to easily arrange the icon images 51 in the group status image 50 in an arrangement relationship similar to the actual position of the reproduction device 10 placed in each room. Therefore, the user 5 can intuitively know the actual position of the reproduction device 10. In addition, it is also possible to arrange the icon images 51 by classifying them for each type of reproduction device 10 to improve operability. Needless to say, it is not limited to this.

[0137] In the case where the destination of the second operation is on the icon images 51 and 55 of the Not Ready device and the non-network device 13, the image control unit 42 returns the selected icon image 51 to the original position. Therefore, for example, it can be easily known that it cannot constitute a group.

[0138] [Disbandment of the group]

[0139] Figure 12 to Figure 14 50G, 50H, and 50I, respectively, in the case where an operation of disbanding a group is input. When disbanding a group, the user 5 inputs a third operation. The third operation is an operation of moving an icon image 51 in the group status image 50 while selecting the icon image 51 of the group device constituting the group.

[0140] like Fig.12 and Fig.13 As shown, it is assumed that the icon image 51e of the main device is selected and moved to a position away from the group image 56 of the group including the main device. As a result, the group is dissolved and the group image 56 is deleted, as shown in FIG. Fig.14 Furthermore, the icon image 51e of the reproduction device which has become the master device is moved to the position where the selection is released.

[0141] As described above, the group can be easily disbanded by simply dragging and dropping the icon image 51 of the main device to a position away from the group image 56. Note that as an image of the disbanded group, any image can be displayed as long as the instruction of the disbandment can be understood. In addition, the instruction that the group is disbanded can be displayed by a text image or the like.

[0142] The position away from the group image 56 is generally a position outside the group image 56. However, it is not limited thereto, and depending on the shape of the group image 56, etc., the inside of the group image 56 may be a position away from the group image 56. In addition, in the case where a predetermined area in the group status image 50 is defined as a group withdrawal area or a disbandment area, the inside of the area is a position away from the group image 56.

[0143] Fig.15 401. The group control unit 42 sends a request to disband the group to the master device (reproduction device A in this example) (step 401). The master device receiving the disband request sends a request to withdraw from the group to all slave devices belonging to the group (reproduction devices B and C in this example) (step 402). When all slave devices are withdrawn, the group is dissolved (step 403). Note that the disbanding of the group can be performed by another method.

[0144] [Withdraw from group]

[0145] Assume that the icon images 51b and 51c of the slave devices of the group devices are selected and moved to a position away from the group image 56 of the group including the slave devices. In this case, the selected slave devices are withdrawn from the group and their images (e.g., Fig. 9 The group status image 50E in Figure 5 As described above, the icon image 51 of the slave device can be easily removed from the group by simply dragging and dropping the icon image 51 to a position away from the group image 56.

[0146] Fig.16 501 is a sequence diagram showing an example of an operation of withdrawing from a group. The group control unit 42 sends a request to withdraw a slave device to the master device (reproduction device A in this example) (step 501). The master device sends a withdrawal request to the reproduction device to be withdrawn (reproduction device C in this example) based on the ID included in the withdrawal request (step 502). As a result, reproduction device C withdraws from the group, and a group configuration including the remaining reproduction devices is left (step 503).

[0147] Note that in the present disclosure, withdrawal means getting rid of the state of the group that constitutes it, that is, eliminating the state of belonging to the group. When the group is dissolved, belonging to the group is inevitably eliminated. Therefore, in the present disclosure, the image of the group dissolution is included in the image of withdrawing the group device from the group (eliminating the image belonging to the group).

[0148] As described above, in the portable terminal 30 according to the present embodiment, it is detected whether each of the plurality of reproduction devices 10 connected to the home network 1 constitutes a group. The group status image 50 including the icon image 51 of each reproduction device 10 is output based on the detection result, and the group status image 50 is controlled in response to the operation performed by the user 5. Therefore, the user 5 can input various operations such as new establishment of a group and new addition to a group while viewing the group status image 50 on one screen. As a result, the reproduction of content can be controlled with good operability.

[0149] The operations that can be input to the group status image 50 are not limited to the above operations. For example, the icon images 51 and 55 of the non-ready device and the non-network device 13 that do not support multi-room reproduction can be selected and moved to a location where there is no icon image 51 of another reproduction device 10. In the case where the destination is on another reproduction device 10, the icon images 51 and 55 are returned to the corresponding original locations.

[0150] In the case where the icon image 51 of the group device is dragged and dropped onto the icon image 51 of another group-ready device located at a position away from the group image 56, a new group including the group device and the group-ready device as the destination can be created, and its group image 56 can be displayed. Furthermore, in the case where the destination of the icon image 51 of the group device is another group image 56, the group image 56 in which the group device is added to the group can be displayed. In the case where the destination is on the icon images 51 and 55 of the not-ready device and the non-network device 13, the icon image 51 is returned to the periphery of the group image 56 (not withdrawn from the group).

[0151] Furthermore, in the case where the icon image 51 of the master device is moved to a position away from the group image 56, the group does not necessarily need to be dissolved, and the group may continue with any of the remaining slave devices as the master device and may display its group image 56. Furthermore, various operations may be input.

[0152] <Other embodiments>

[0153] The present technology is not limited to the above-described embodiments, and other various embodiments can be implemented.

[0154] Fig.17 is a diagram showing a configuration example of a group state image 50J that displays meta information related to content. For example, meta information 60 related to content reproduced by a plurality of group devices included in the same group may be displayed in the group state image 50J. Fig.17 In the example shown, the content name 61 and the artist image 62 are displayed as the meta information. However, it is not limited to this.

[0155] For example, in the above-described embodiment, the content provided from the server device 20 on the home network 1 is described as an example of the content for which multi-room reproduction is performed. However, it is not limited to this, and content read by the group-ready device via a CD or USB or content acquired by the group-ready device from a predetermined service such as the Internet may be reproduced. In this case, as the meta-information 60, information 63 indicating the acquisition destination of the content (location of the content) may be displayed.

[0167] By displaying the reproduction information image as described above, it is possible to perform reproduction settings, EQ settings, etc. for each group with simple operations. Specifically, it is possible to centrally perform reproduction settings, etc. for multiple group devices, and to exert high operability. It goes without saying that an image including information different from the above may be displayed as a reproduction information image.

[0168] By selecting the icon image 51 of the reproduction device 10 that performs normal reproduction other than multi-room reproduction, the reproduction information image 70 related to normal reproduction can be output. It can be said that the reproduction information image is a functional image related to multi-room reproduction or normal reproduction.
