Next, FIG. 3 is a block diagram showing the main configuration of the smartphone 2. The smartphone 2 includes a touch panel 301, a control unit 302, a ROM 303, a RAM 304, a display unit 305, and a communication I / F 306. The smartphone 2 is an example of an information processing device.

The touch panel 301 corresponds to a reception unit that receives an operation from a user. The display unit 305 presents various information to the user. The smartphone 2 implements GUI (Graphical User Interface) by the touch panel 301 and the display unit 305.

The control unit 302 performs various operations by reading out the OS and application programs stored in the ROM 303, which is a storage medium, to the RAM 304. In the example illustrated in FIG. 3, the control unit 302 functions as a movement information reception unit 391, a reproduction management information movement unit 392, and a display processing unit 393. When the activation of the application program is instructed by the user via the touch panel 301, the display processing unit 393 activates the instructed application program and displays the screen of the application program on the display unit 305.

FIG. 4A shows an example of the application program screen. FIG. 5 is a flowchart showing the operation of the smartphone 2. FIG. 6 is a diagram illustrating a flow of information between apparatuses.

On the screen shown in FIG. 4A, a group name “Room1” indicating the installation location is displayed as a group of synchronized playback formed by the first playback device 1A, the first slave device 11A, and the second slave device 11B. Yes.

The first playback device 1A plays back and distributes content based on playback management information. The reproduction management information includes list information, an index, a reproduction position, and setting information as shown in FIG. The list information is information indicating the contents of an arbitrary content list selected by the user, as shown in FIG. The index is information indicating what number content is currently being reproduced in the list information. The reproduction position is information indicating the reproduction position (elapsed time from the start of reproduction) of the content currently being reproduced. The setting information is information indicating whether or not repeat playback is performed and whether or not random playback is performed. Repeat indicates whether or not the content currently being reproduced is repeatedly reproduced, or whether or not the content in the front row is reproduced after reproduction at the end of the list. Random playback includes information indicating the playback order after the contents listed in the list information are randomly sorted.

As shown in FIG. 4 (A), the audio data of the song title “Contents A” is currently being played in Room 1. That is, in the list information shown in FIG. 7, the song name “Contents A”, which is the content in the front row, is reproduced.

Here, there is a case where the user moves from Room 1 to Room 2 and wants to hear the continuation of the content that is currently being played in Room 2. In this case, the user presses the movement button 502. As a result, as shown in FIG. 5, the first playback device 1A is accepted as the playback device of the movement source (S11). When the movement button 502 is pressed, the display processing unit 393 displays a room selection screen as shown in FIG. 4B (S12). When the user selects the destination Room (Room 2 in this example) (Yes in S13), the master unit (second playback device 1B in this case) corresponding to the selected Room is designated as the destination playback device. .

The movement information reception unit 391 receives movement information indicating the movement source reproduction apparatus and the movement destination reproduction apparatus as described above. In the example of FIG. 4A and FIG. 4B, the first playback device 1A is the playback device that is the movement source, and the second playback device 1B is the playback device that is the movement destination.

Next, based on the movement information, the reproduction management information moving unit 392 performs a process of moving the content reproduction management information in the movement-source first reproduction device 1A to the movement-destination second reproduction device 1B.

In the flowchart of FIG. 5 and the data flow of FIG. 6, the reproduction management information moving unit 392 first obtains reproduction management information from the first reproduction apparatus 1A as the movement source (S14). Then, the reproduction management information moving unit 392 transmits the acquired reproduction management information to the second reproduction apparatus 1B that is the movement destination (S15).

The second playback device 1B acquires the playback management information transmitted from the smartphone 2 (S21), and plays back the content based on the acquired playback management information (S22). The reproduction management information includes information (Source) for specifying a device in which the content is stored and information (SongID) for specifying the target content.

The source includes, for example, identification information for uniquely identifying a device such as a device name, IP address, or identification information (such as a manufacturer ID or MAC address), and information indicating an interface for inputting content data. include.

The Song ID may be identification information for uniquely identifying the target content, or may be information indicating a directory selection position. For example, when the content of the above-mentioned song name AAA is stored as the second data in the uppermost directory of the USB device, information “1/2” is set as SongID as information indicating the selected position.

Note that the content acquisition destination is not necessarily a device in the distribution system. For example, content data held in an external server may be downloaded (or streamed). In this case, like the content indicated by SongID0010 in FIG. 7, the reproduction management information indicates the address (URL) of the external server. The source of content may be an album such as media. In this case, the reproduction management information includes a source, an album ID, and an index within the album.

As described above, also in the second playback device 1B, the content played back in the first playback device 1A is played back. Thereafter, the smartphone 2 transmits information for instructing to stop the reproduction to the first reproduction apparatus 1A that is the movement source (S16). When the first playback device 1A receives information instructing to stop playback (S31), the first playback device 1A stops playback of the content (S32). However, it is not indispensable to stop the playback in the playback device of the movement source.

As a result, as shown in FIG. 4C, the content listened to in Room 1 is also reproduced in the destination Room 2. Since the reproduction management information includes reproduction position information, the content is continuously reproduced from the reproduction position of Room 1 even in Room 2. However, the reproduction position information is not essential. In the destination Room 2, playback may be started from the beginning of the song name “Contents A” that was played back in Room 1.

Thus, in the distribution system of the present embodiment, the continuation of the content can be reproduced even when the user has moved.

Next, FIG. 8 is a flowchart showing the operation of each device according to the first modification. The same processes as those in the flowchart shown in FIG. In the first modification, the smartphone 2 instructs the first playback device 1A to transmit the playback management information to the second playback device 1B (S104).

When the first playback device 1A receives the instruction (S201), the first playback device 1A transmits playback management information to the second playback device 1B that is the movement destination (S202).

The second playback device 1B receives the playback management information from the first playback device 1A (S21), and plays back the content based on the received playback management information (S22). Note that the first playback device 1A may stop playback of the content after the process of S202.

FIG. 9 is a flowchart showing the operation of each device according to the second modification. The same processes as those in the flowchart shown in FIG. In the first modification, the smartphone 2 instructs the second playback device 1B to acquire the playback management information from the first playback device 1A (S154).

When the second playback device 1B receives the instruction (S301), the second playback device 1B requests the first playback device 1A that is the movement source to transmit playback management information (S302). When receiving the request (S401), the first playback device 1A transmits playback management information to the second playback device 1B (S402). Note that the first playback device 1A may stop playback of the content after the process of S401.

The second playback device 1B receives the playback management information from the first playback device 1A (S21), and plays back the content based on the received playback management information (S22).

Next, FIG. 10 is a diagram showing an application screen according to the third modification. In the third modification, as shown in FIG. 10A, the user presses the movement button 502 on the reproduction screen of Room 2 as the movement destination. As a result, the second playback device 1B is accepted as a destination playback device. When the move button 502 is pressed, the display processing unit 393 displays a room selection screen as shown in FIG. When the user selects the source Room (Room 1 in this example), the master unit (here, the first playback device 1A) corresponding to the selected Room is designated as the source playback device.

Therefore, also in this case, as shown in FIG. 10C, the content listened to in Room 1 is also reproduced in the destination Room 2.

Next, FIG. 11 is a diagram showing an application screen according to the fourth modification. In the fourth modification, an error notification is performed when reproduction management information cannot be transferred on the selection screen of the movement destination (or movement source).

As shown in FIG. 11A, when the move button 502 is pressed on the playback screen of Room 1, the display processing unit 393 displays a move destination selection screen as shown in FIG. 11B. Here, for example, in the third playback device 1C installed in Room 3, if the audio data of the song name “Contents A” cannot be decoded and the content cannot be played back, the display processing unit 393 displays Room 3 in gray. Further, for example, when the third playback device 1C is temporarily unable to communicate and cannot receive playback management information, Room 3 may be displayed in gray. Further, as shown in FIG. 11C, when the reproduction management information is received but the designated content cannot be acquired and the content cannot be reproduced, an error display is displayed by displaying “Source Error” or the like. You may do it. In this example, the display processing unit 393 functions as an error notification unit, but an error notification may be performed by voice, for example.

Next, FIG. 12 is a diagram showing a configuration in a case where reproduction management information is transmitted / received mainly between reproduction apparatuses as a fifth modification. In the modified example 5, the distribution system 900 does not include the smartphone 2. Instead, a physical button 100 is installed in each room. The physical button 100 may be provided in the playback device or may be provided as room equipment. Further, instead of the physical button 100, a user operation may be received using a display unit (not shown) and an operation unit (not shown) provided in the first playback device 1A.

In Modification 5, the user uses the physical button 100 to specify a playback device that is a movement source and a playback device that is a movement destination. For example, when the physical button 100 is pressed during reproduction of content, the reproduction device that is reproducing the content is designated as the movement source. When the physical button 100 is pressed while content is not being played back, the playback device is designated as the destination. Alternatively, it is designated as the movement source when the physical button 100 is pressed long, and is designated as the movement destination when the physical button 100 is single-pressed. Further, a mode in which a plurality of buttons are provided, such as “movement source button” and “movement destination button”, is also possible.

The playback device specified as the movement destination searches for the playback device specified as the movement source, and acquires the playback management information from the playback device specified as the movement source. Alternatively, the reproduction device designated as the movement source searches for the reproduction device designated as the movement destination, and transmits reproduction management information to the reproduction device designated as the movement destination.

For example, before leaving the Room 1, the user presses the physical button to specify the first playback device 1A as the movement source, and presses the physical button in Room 3 to specify the third playback device 1C as the movement destination. Then, the content that was being played on Room 1 is played on Room 3. Therefore, the user can listen to the continuation of the content that has been listened to in Room 1 in Room 3.

Note that the movement of the user can also be detected by detecting the position of the terminal owned by the user. As a method for detecting the position of the terminal, for example, GPS may be used, or radio wave intensity in a wireless LAN or Bluetooth (registered trademark) may be used. For example, a terminal that transmits and receives a beacon signal in accordance with the Bluetooth Low Energy standard (hereinafter referred to as BLE) is provided in each room. And a user carries the smart phone 2 which transmits / receives a beacon signal. The smartphone 2 transmits a beacon signal. The terminal in each room measures the distance from the user terminal based on the received radio wave intensity of the beacon signal received from the smartphone 2. The measured distance is transmitted to the playback device in each room. When the received distance is less than a predetermined value, the playback device accepts the device as a destination device. Conversely, when the received distance is equal to or greater than a predetermined value, the playback device accepts the own device as the source device.

In this way, it is also possible to detect the movement of the user and accept movement information indicating the movement source reproduction apparatus and the movement destination reproduction apparatus in accordance with the detected movement of the user.

In the above-described embodiment, the first playback device 1A and the second playback device 1B each function as a master unit that distributes content. However, distribution is not essential in the present invention.

The description of the above-described embodiment is an example in all respects, and should be considered as not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the claims.
