DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of an information processing device and an information processing method according to the present disclosure will be described with reference to the accompanying drawings.

Note that the application of the system 1 is not limited to an RSE.

[0018] FIG. 2 is a diagram illustrating an example of a hardware configuration of the information processing device 10 and the display device 30. As shown in FIG.

[0019] The information processing device 10 and the display device 30 have a hardware configuration that utilizes a normal computer, with a CPU (Central Processing Unit) 11D, a ROM (Read Only Memory) 11E, a RAM (Random Access Memory) 11F, and an I / F (Interface) 11G, etc., interconnected by a bus 11H.

The I / F 11G is an interface for transmitting and receiving data.

[0021] The programs for executing information processing executed by the information processing device 10 and the display device 30 are provided by being pre-installed in a ROM 11E or the like. The programs executed by the information processing device 10 and the display device 30 may be provided by being recorded in a computer-readable recording medium such as a CD-ROM, a flexible disk (FD), a CD-R, or a digital versatile disc (DVD) in a format that can be installed or executed on the information processing device 10 and the display device 30.

[0022] Next, the system 1 will be described in detail.

[0023] FIG. 3 is a block diagram showing an example of the functional configuration of the system 1. As shown in FIG.

[0024] The system 1 includes an information processing device 10, a second display device 32, a first display device 31, a first audio output device 41, and a second audio output device 42. The information processing device 10, the first display device 31, and the second display device 32 are connected to each other so as to be able to communicate with each other.

[0025] First, the first display device 31 and the second display device 32 will be described.

[0026] The first display device 31 is an example of the display device 30. The first display device 31 includes a first input circuit 31A, a first control information input circuit 31B, a first display device control circuit 31C, a first power supply 31D, a first wireless communication circuit 31E, and a first display panel 31F.

[0027] The first input circuit 31A, the first control information input circuit 31B, the first power supply 31D, the first wireless communication circuit 31E, the first display panel 31F, and the first display device control circuit 31C are connected so as to be able to exchange data or signals.

[0028] The first input circuit 31A is connected to the first output circuit 10E of the information processing device 10 in a one-to-one communication manner. The first input circuit 31A receives first video and audio from the first output circuit 10E of the information processing device 10 and outputs the first video and audio to the first display device control circuit 31C. The first video and audio is an example of video and audio.

[0029] The first control information input circuit 31B is communicatively connected to the control information output circuit 10F of the information processing device 10. The first control information input circuit 31B receives various types of control information output under the control of the control circuit 10D from the control information output circuit 10F, and outputs the information to the first display device control circuit 31C.

[0030] The first power source 31D supplies power to each unit of the first display device 31. The first power source 31D is configured to be switchable so as to supply or cut off power to each unit of the first display device 31 in response to an operation instruction from a user, control information received from the information processing device 10, or the like.

[0031] The first wireless communication circuit 31E wirelessly outputs audio to the audio output device 40. The first wireless communication circuit 31E performs Bluetooth communication with the audio output device 40 that is capable of Bluetooth communication.

[0032] The first wireless communication circuit 31E supports at least one of a multicast protocol and a broadcast protocol, and performs transmission and reception of multicast audio (two-way communication) and transmission and reception of broadcast audio by wireless communication. The first wireless communication circuit 31E can also receive signals from multiple audio output devices 40.

[0033] The first wireless communication circuit 31E wirelessly communicates with the audio output device 40 using Bluetooth LE (Low energy) Audio. Bluetooth LE Audio is a Bluetooth audio standard that allows simultaneous Bluetooth communication with multiple audio output devices 40. Therefore, the first wireless communication circuit 31E is configured to be able to perform one-to-multiple wireless communication with multiple audio output devices 40.

[0034] In this embodiment, in an initial state, the first wireless communication circuit 31E outputs audio to the first audio output device 41 via wireless communication under the control of the first display device control circuit 31C. Also, the first wireless communication circuit 31E outputs audio to the first audio output device 41 and the second audio output device 42 via wireless communication under the control of the first display device control circuit 31C. Details of these controls will be described later.

[0035] In the present embodiment, a configuration in which the first wireless communication circuit 31E outputs audio to the audio output device 40 by multicast using a multicast protocol will be described as an example. For this reason, the description will be made assuming that the first wireless communication circuit 31E is pre-paired with the first audio output device 41 and the second audio output device 42. The first wireless communication circuit 31E may also be configured to output audio to the audio output device 40 by broadcast using a broadcast protocol.

[0036] The first display panel 31F is a display such as a liquid crystal display or an organic EL (Electro-Luminescence) display. In this embodiment, an image is displayed in a first display area D1 of the first display panel 31F (see also FIG. 1). The first display area D1 is an example of a display area D, and is an area where an image is displayed. The display area D is sometimes referred to as a display screen.

[0037] The first display device control circuit 31C controls at least one of the first display panel 31F and the first wireless communication circuit 31E in accordance with control information received from the information processing device 10. For example, the first display device control circuit 31C outputs the first video included in the first video and audio received from the first output circuit 10E via the first input circuit 31A to the first display region D1 of the first display panel 31F in accordance with the control information. Furthermore, the first display device control circuit 31C controls the first wireless communication circuit 31E in accordance with the control information so as to output the first audio included in the first video and audio received from the first output circuit 10E via the first input circuit 31A to the audio output device 40. Details of the control by the first display device control circuit 31C will be described later.

[0038] The second display device 32 is an example of the display device 30. The second display device 32 is a display device 30 configured separately from the first display device 31, and has the same configuration as the first display device 31.

[0039] In detail, the second display device 32 includes a second input circuit 32A, a second control information input circuit 32B, a second display device control circuit 32C, a second power supply 32D, a second wireless communication circuit 32E, and a second display panel 32F.

[0040] The second input circuit 32A, the second control information input circuit 32B, the second power supply 32D, the second wireless communication circuit 32E, the second display panel 32F, and the second display device control circuit 32C are connected so as to be able to exchange data or signals.

[0041] The second input circuit 32A is connected to the second output circuit 10G of the information processing device 10 in a one-to-one communication manner. The second input circuit 32A receives second video and audio from the second output circuit 10G of the information processing device 10 and outputs the second video and audio to the second display device control circuit 32C. The second video and audio is an example of video and audio.

[0042] The second control information input circuit 32B is communicatively connected to the control information output circuit 10F of the information processing device 10. The second control information input circuit 32B receives various types of control information output under the control of the control circuit 10D from the control information output circuit 10F, and outputs the information to the second display device control circuit 32C.

[0043] The second power source 32D supplies power to each unit of the second display device 32. The second power source 32D is configured to be switchable so as to supply or cut off power to each unit of the second display device 32 in response to an operation instruction from a user, control information received from the information processing device 10, or the like.

[0044] The second wireless communication circuit 32E wirelessly outputs audio to the audio output device 40. Like the first wireless communication circuit 31E, the second wireless communication circuit 32E performs Bluetooth communication with the audio output device 40 that is capable of Bluetooth communication.

[0045] The second wireless communication circuit 32E, like the first wireless communication circuit 31E, supports at least one of a multicast protocol and a broadcast protocol. The second wireless communication circuit 32E transmits and receives multicast audio and broadcast audio via wireless communication. The second wireless communication circuit 32E can also receive signals from multiple audio output devices 40.

[0046] Similar to the first wireless communication circuit 31E, the second wireless communication circuit 32E wirelessly communicates with the audio output device 40 by Bluetooth LE Audio. Therefore, the second wireless communication circuit 32E is configured to be able to perform one-to-many wireless communication with a plurality of audio output devices 40.

[0047] In this embodiment, in an initial state, the second wireless communication circuit 32E outputs audio to the second audio output device 42 via wireless communication under the control of the second display device control circuit 32C. Also, the second wireless communication circuit 32E is switched to a power saving mode under the control of the second display device control circuit 32C.

[0048] The power saving mode is a mode in which at least audio output is stopped. When the second wireless communication circuit 32E is switched to the power saving mode, wireless communication is stopped. The second display device control circuit 32C controls the second wireless communication circuit 32E to stop audio output to the audio output device 40, or controls the second wireless communication circuit 32E to cut off power supplied to the second wireless communication circuit 32E. Through these controls, the second display device control circuit 32C controls the second wireless communication circuit 32E to operate in the power saving mode.

[0049] In addition, in the present embodiment, a configuration will be described as an example in which the second wireless communication circuit 32E outputs audio to the audio output device 40 by multicast using a multicast protocol, similar to the first wireless communication circuit 31E. In the present embodiment, the description will be made assuming that the second wireless communication circuit 32E is pre-paired with at least the second audio output device 42. Note that the second wireless communication circuit 32E may also be configured to output audio to the audio output device 40 by broadcast using a broadcast protocol.

[0050] The second display panel 32F is a display such as a liquid crystal display or an organic EL display. In this embodiment, an image is displayed in the second display area D2 of the second display panel 32F (see also FIG. 1). The second display area D2 is an example of the display area D, and is an area where an image is displayed.

[0051] The second display device control circuit 32C controls at least one of the second display panel 32F and the second wireless communication circuit 32E in response to control information received from the information processing device 10. For example, in response to the control information, the second display device control circuit 32C outputs the second video included in the second video and audio received from the second output circuit 10G via the second input circuit 32A to the second display area D2 of the second display panel 32F. In response to the control information, the second display device control circuit 32C also controls the second wireless communication circuit 32E to output the second audio included in the second video and audio received from the second output circuit 10G via the second input circuit 32A to the second audio output device 42. In response to the control information, the second display device control circuit 32C also operates the second wireless communication circuit 32E in a power-saving mode. Details of the control by the second display device control circuit 32C will be described later.

[0052] Next, the information processing device 10 of this embodiment will be described in detail.

[0053] The information processing device 10 includes a wired LAN (Local Area Network) communication circuit 10A, a wireless LAN communication circuit 10B, an external device connection circuit 10C, a control circuit 10D, a first output circuit 10E, a control information output circuit 10F, and a second output circuit 10G. The wired LAN communication circuit 10A, the wireless LAN communication circuit 10B, the external device connection circuit 10C, the first output circuit 10E, the control information output circuit 10F, and the second output circuit 10G are communicatively connected to the control circuit 10D.

[0054] The wired LAN communication circuit 10A is connected to the Internet via a gateway or the like, and transmits and receives data such as video and audio to and from a server. The wired LAN communication circuit 10A is also connected to an STB (Set Top Box) or the like, and receives video and audio from the STB, such as cable broadcasting, satellite broadcasting, terrestrial television broadcasting, IP (Internet Protocol) broadcasting (broadband), and VOD (Video On Demand).

[0055] The wireless LAN communication circuit 10B transmits and receives data to and from wireless communication devices such as smartphones, tablets, etc. The wireless LAN communication circuit 10B can also connect to the Internet via an access point or the like.

[0056] The external device connection circuit 10C communicates with external devices wirelessly or via wires. The external devices are devices that transmit and receive uncompressed video signals using HDMI (High-Definition Multimedia Interface) (registered trademark) or the like, such as personal computers, projectors, and home theater devices.

[0057] The first output circuit 10E is connected one-to-one to the first input circuit 31A of the first display device 31, and outputs first video and audio to the first display device 31. The second output circuit 10G is connected one-to-one to the second input circuit 32A of the second display device 32, and outputs second video and audio to the second display device 32. The first video and audio and the second video and audio are examples of video and audio.

[0058] The control information output circuit 10F outputs the control information to the display device 30 under the control of the control circuit 10D.

[0059] The control circuit 10D executes various information processes in the information processing device 10. For example, the control circuit 10D causes the CPU 11D to read a program from the ROM 11E onto the RAM 11F and execute the program, thereby realizing each of the later-described functional units of the processing unit 20 on the computer.

[0060] A part or all of the control circuit 10D may be realized by causing a processing device such as a CPU 11D to execute a program, i.e., by software, or by hardware such as an IC (Integrated Circuit), or by a combination of software and hardware. Also, at least one of the functional units that execute the processing in 20D may be mounted on an external information processing device communicatively connected to the information processing device 10 via a network or the like.

[0061] The control circuit 10D acquires a plurality of video and audio signals to be output to the display device 30 from at least one of the wired LAN communication circuit 10A, the wireless LAN communication circuit 10B, and the external device connection circuit 10C. The control circuit 10D may also acquire a plurality of video and audio signals to be output to the display device 30 from a storage unit provided in the information processing device 10. In this embodiment, an example will be described in which the control circuit 10D acquires a first video and audio signal and a second video and audio signal as video and audio signals to be output to the display device 30.

[0062] The control circuit 10D outputs the first video and audio to the first output circuit 10E. The first output circuit 10E outputs the first video included in the first video and audio to the first display area D1, and outputs the first audio included in the first video and audio to the first wireless communication circuit 31E.

[0063] Furthermore, the control circuit 10D outputs the second video and audio to the second output circuit 10G. The second output circuit 10G outputs the second video included in the second video and audio to the second display area D2, and outputs the second audio included in the second video and audio to the second wireless communication circuit 32E.

[0064] The control circuit 10D determines whether the first video and audio and the second video and audio are the same video and audio. The control circuit 10D may determine whether the two video and audio are the same video and audio by a known method.

[0065] When the control circuit 10D determines that the first video and audio and the second video and audio are the same video and audio, the control circuit 10D operates the second wireless communication circuit 32E in the power saving mode. Specifically, the control circuit 10D outputs a control signal instructing the second wireless communication circuit 32E to operate in the power saving mode to the second control information input circuit 32B via the control information output circuit 10F.

[0066] The second display device control circuit 32C of the second display device 32, which receives the control signal from the control information output circuit 10F via the second control information input circuit 32B, switches the second wireless communication circuit 32E to a power saving mode. In particular, the second display device control circuit 32C, which receives the control signal, controls the second wireless communication circuit 32E to stop outputting audio to the audio output device 40, or controls the second power supply 32D to cut off power supplied to the second wireless communication circuit 32E. Through these controls, the second display device control circuit 32C switches the second wireless communication circuit 32E to a power saving mode.

[0067] By operating the second wireless communication circuit 32E in a power saving mode, the wireless communication connection between the second wireless communication circuit 32E and the second audio output device 42 is disconnected, and the output of the second audio from the second wireless communication circuit 32E to the second audio output device 42 is stopped.

[0068] Then, the control circuit 10D controls the first wireless communication circuit 31E so as to output the first audio included in the first video and audio to the first audio output device 41 and the second audio output device .

[0069] Therefore, if it is determined that the first video and audio and the second video and audio are the same video and audio, the second wireless communication circuit 32E is switched to a power saving mode, and the first audio is output from the first wireless communication circuit 31E to the first audio output device 41 and the second audio output device 42.

[0070] Here, priority order information indicating the priority of the wireless communication circuit to be connected via wireless communication may be registered in advance in each of the first audio output device 41 and the second audio output device .

[0071] In this embodiment, wireless communication circuit identification information for identifying the first wireless communication circuit 31E in association with first priority order information representing the highest priority order "1" is pre-registered in the first audio output device 41. Also, wireless communication circuit identification information for identifying the second wireless communication circuit 32E in association with second priority order information representing the next highest priority order "2" is pre-registered in the first audio output device 41.

[0072] Furthermore, wireless communication circuit identification information for identifying the second wireless communication circuit 32E in association with first priority order information representing the highest priority order "1" is pre-registered in the second audio output device 42. Furthermore, wireless communication circuit identification information for identifying the first wireless communication circuit 31E in association with second priority order information representing the next highest priority order "2" is pre-registered in the second audio output device 42.

[0073] The first priority information and the second priority information are examples of priority information.

[0074] When the first audio output device 41 and the second audio output device 42 are able to receive audio via wireless communication from each of the first wireless communication circuit 31E and the second wireless communication circuit 32E, they receive and output audio from the wireless communication circuit with the higher priority. When the first audio output device 41 and the second audio output device 42 are unable to receive audio from the wireless communication circuit with the highest priority, they receive audio from the wireless communication circuit with the next highest priority.

[0075] Assume that the second wireless communication circuit 32E is in a power saving mode and the output of the second audio via wireless communication from the second wireless communication circuit 32E is stopped. In this case, the second audio output device 42 is in a state where it cannot receive the second audio from the second wireless communication circuit 32E identified by the wireless communication circuit identification information associated with the priority information having a higher priority. In other words, the second audio output device 42 is in a state where it has stopped receiving the second audio from the second wireless communication circuit 32E identified by the wireless communication circuit identification information associated with the first priority information having the highest priority level of "1."

[0076] In this case, the second audio output device 42 receives the first audio from the first wireless communication circuit 31E identified by the wireless communication circuit identification information associated with the lower priority information. In detail, the second audio output device 42 receives and outputs the first audio from the first wireless communication circuit 31E identified by the wireless communication circuit identification information associated with the second priority information of the next priority level, "2."

[0077] Therefore, when priority order information is registered in advance in the audio output device 40, the control circuit 10D can control the first wireless communication circuit 31E to output the first audio included in the first video and audio to the first audio output device 41 and the second audio output device 42 by operating the second wireless communication circuit 32E in the power saving mode. In other words, when priority order information is registered in advance in the audio output device 40, the control circuit 10D can control the first wireless communication circuit 31E with simple control to output the first audio included in the first video and audio to the first audio output device 41 and the second audio output device 42.

[0078] Note that the first audio output device 41 and the second audio output device 42 may not have pre-registered priority order information indicating the priority of the wireless communication circuit to be connected via wireless communication.

[0079] In this case, if the control circuit 10D determines that the first video audio and the second video audio are the same video audio, it operates the second wireless communication circuit 32E in a power saving mode and transmits control information to the first display device 31 to control the first wireless communication circuit 31E to output the first audio to the first audio output device 41 and the second audio output device 42.

[0080] In detail, before determining that the first video and the second video are the same video, i.e., in the initial state, the control circuit 10D controls the first wireless communication circuit 31E to output the first audio to the first audio output device 41, with the first audio output device 41 being the only output destination. In addition, the control circuit 10D controls the second wireless communication circuit 32E to output the second audio to the second audio output device 42, with the second audio output device 42 being the only output destination.

[0081] Then, when the control circuit 10D determines that the first video audio and the second video audio are the same video audio, it controls the first wireless communication circuit 31E to output the first audio to both the first audio output device 41 and the second audio output device 42 as output destinations.

[0082] The first wireless communication circuit 31E and the second wireless communication circuit 32E may be capable of using both a multicast protocol and a broadcast protocol and may be capable of outputting audio to the audio output device 40 by multicast or broadcast. In this case, in the initial state, i.e., before determining that the first video and the second video are the same video, the control circuit 10D controls the first wireless communication circuit 31E to output the first audio to the first audio output device 41 by multicast, with only the first audio output device 41 as the output destination. The control circuit 10D also controls the second wireless communication circuit 32E to output the second audio to the second audio output device 42 by multicast, with only the second audio output device 42 as the output destination. Then, when the control circuit 10D determines that the first video and audio and the second video and audio are the same video and audio, the control circuit 10D may control the first wireless communication circuit 31E to output the first audio to both the first audio output device 41 and the second audio output device 42 by broadcast.

[0083] Through these controls, when the control circuit 10D determines that the first video audio and the second video audio are the same video audio, it controls the first wireless communication circuit 31E to operate the second wireless communication circuit 32E in a power saving mode and output the first audio to the first audio output device 41 and the second audio output device 42.

[0084] Then, the control circuit 10D controls the first output circuit 10E to output the first video to the first display region D1, and controls the second output circuit 10G to output the second video to the second display region D2. That is, the first output circuit 10E outputs the first video to the first display region D1 of one or more display devices 30, and the second output circuit 10G outputs the second video to the second display region D2 of one or more display devices 30.

[0085] In this embodiment, the first output circuit 10E outputs the first video to the first display region D1 of the first display panel 31F of the first display device 31. The second output circuit 10G outputs the second video to the second display region D2 of the second display panel 32F of the second display device 32 (see also FIG. 1).

[0086] Specifically, when the first display device control circuit 31C of the first display device 31 receives the first video and audio from the first output circuit 10E of the information processing device 10 via the first input circuit 31A, it outputs the first video included in the first video and audio to the first display region D1 of the first display panel 31F. When the second display device control circuit 32C of the second display device 32 receives the second video and audio from the first output circuit 10E via the second input circuit 32A, it outputs the second video included in the second video and audio to the second display region D2 of the second display panel 32F. Therefore, as shown in FIG. 1 , the first video is displayed in the first display region D1 of the first display panel 31F, and the second video is displayed in the second display region D2 of the second display panel 32F. When the first video and audio and the second video and audio are the same video and audio, the same video is displayed in the first display region D1 and the second display region D2.

[0087] On the other hand, if the control circuit 10D determines that the first video audio and the second video audio are different video audio, it controls the first wireless communication circuit 31E to output the first audio to the first audio output device 41, and controls the second wireless communication circuit 32E to output the second audio to the second audio output device 42.

[0088] If the control circuit 10D determines that the first video audio and the second video audio are different video audio and that the second wireless communication circuit 32E is in a power saving mode, it controls the second wireless communication circuit 32E to cancel the power saving mode, and then controls the second wireless communication circuit 32E to output the second audio to the second audio output device 42.

[0089] As in the above, it is assumed that priority order information indicating the priority of the wireless communication circuit to be wirelessly connected is pre-registered in each of the first audio output device 41 and the second audio output device 42. As in the above, it is assumed that wireless communication circuit identification information for identifying the first wireless communication circuit 31E in association with the first priority order information is pre-registered in the first audio output device 41, and wireless communication circuit identification information for identifying the second wireless communication circuit 32E in association with the second priority order information, which is the next priority order, is pre-registered in the second audio output device 42. It is also assumed that wireless communication circuit identification information for identifying the second wireless communication circuit 32E in association with the first priority order information is pre-registered in the second audio output device 42, and wireless communication circuit identification information for identifying the first wireless communication circuit 31E in association with the second priority order information, which is the next priority order, is pre-registered in the second audio output device 42.

[0090] In this case, when the power saving mode of the second wireless communication circuit 32E is released and the second wireless communication circuit 32E starts to output the second audio via wireless communication, the second audio output device 42 receives the second audio from the second wireless communication circuit 32E identified by the wireless communication circuit identification information associated with the higher priority information. Also, the first audio output device 41 receives the first audio from the first wireless communication circuit 31E identified by the wireless communication circuit identification information associated with the higher priority information.

[0091] Therefore, when priority order information is registered in advance in the audio output device 40, the control circuit 10D can cancel the power saving mode of the second wireless communication circuit 32E to control the first wireless communication circuit 31E to output the first audio included in the first video and audio to the first audio output device 41, and control the second wireless communication circuit 32E to output the second audio included in the second video and audio to the second audio output device 42. In other words, when priority order information is registered in advance in the audio output device 40, the control circuit 10D can control each of the first wireless communication circuit 31E and the second wireless communication circuit 32E with simple control to output the first audio to the first audio output device 41 and the second audio to the second audio output device 42.

[0092] Similarly to the above, priority information indicating the priority of the wireless communication circuit to be connected via wireless communication may not be pre-registered in each of the first audio output device 41 and the second audio output device 42.

[0093] In this case, if the control circuit 10D determines that the first video audio and the second video audio are different video audio, it transmits control information to each of the first display device 31 and the second display device 32 to control the first wireless communication circuit 31E to output the first audio to the first audio output device 41 and the second wireless communication circuit 32E to output the second audio to the second audio output device 42.

[0094] In detail, the control circuit 10D transmits a control signal indicating that the first audio is to be output to the first audio output device 41 only as an output destination to the first display device 31 via the control information output circuit 10F. The first display device control circuit 31C, having received the control signal via the first control information input circuit 31B, controls the first wireless communication circuit 31E to output the first audio to the first audio output device 41 only as an output destination. Furthermore, the control circuit 10D transmits a control signal indicating that the second audio is to be output to the second audio output device 42 only as an output destination to the second display device 32 via the control information output circuit 10F. The second display device control circuit 32C, having received the control signal via the second control information input circuit 32B, controls the second wireless communication circuit 32E to output the second audio to the second audio output device 42 only as an output destination.

[0095] Through these controls, when the control circuit 10D determines that the first video audio and the second video audio are different video audio, it controls the first wireless communication circuit 31E to output the first audio to the first audio output device 41, and controls the second wireless communication circuit 32E to output the second audio to the second audio output device 42.

[0096] Then, the control circuit 10D controls the first output circuit 10E to output the first video to the first display region D1, and controls the second output circuit 10G to output the second video to the second display region D2. That is, the first output circuit 10E outputs the first video to the first display region D1 of the first display device 31, and the second output circuit 10G outputs the second video to the second display region D2 of the second display device 32. Therefore, as shown in FIG. 1, the first video is displayed in the first display region D1 of the first display panel 31F, and the second video is displayed in the second display region D2 of the second display panel 32F. Furthermore, if the first video and audio and the second video and audio are different video and audio, different videos will be displayed in the first display region D1 and the second display region D2.

[0097] In addition, the control circuit 10D may determine whether the system 1 is in the first power state or the second power state, and if it determines that the system 1 is in the first power state, may determine whether the first video and audio and the second video and audio are the same video and audio.

[0098] The first power state means that the first wireless communication circuit 31E is in an ON state in which power is supplied, and the second wireless communication circuit 32E is in an OFF state in which power supply is cut off. In this embodiment, an example will be described in which the first wireless communication circuit 31E is mounted on the first display device 31, and the second wireless communication circuit 32E is mounted on the second display device 32. For this reason, in this embodiment, the first power state will be described assuming that the first display device 31 is in an ON state in which power is supplied, and the second display device 32 is in an OFF state in which power supply is cut off.

[0099] The second power state refers to an ON state in which both the first wireless communication circuit 31E and the second wireless communication circuit 32E are supplied with power. In this embodiment, an example will be described in which the first wireless communication circuit 31E is mounted on the first display device 31 and the second wireless communication circuit 32E is mounted on the second display device 32. For this reason, in this embodiment, the description will be made assuming a case in which the second power state represents an ON state in which both the first display device 31 and the second display device 32 are supplied with power.

[0100] For example, the control circuit 10D transmits control information inquiring about the power supply state to each of the first display device 31 and the second display device 32 via the control information output circuit 10F. Then, if the control circuit 10D receives a response signal indicating an ON state from the first display device 31 within a predetermined time in response to the control information, and does not receive a response signal indicating an ON state or receives a response signal indicating an OFF state from the second display device 32 within the predetermined time, the control circuit 10D determines that the first power state is being established.

[0101] Furthermore, for example, the control circuit 10D transmits control information inquiring about the power supply state to each of the first display device 31 and the second display device 32 via the control information output circuit 10F. Then, when the control circuit 10D receives a response signal indicative of an ON state from the first display device 31 within a predetermined time in response to the control information, and receives a response signal indicative of an ON state from the second display device 32 within the same predetermined time, the control circuit 10D determines that the display device is in the second power state.

[0102] When the control circuit 10D determines that it is in the second power state, it determines whether the first video and audio and the second video and audio are the same video and audio, and executes the same process as above.

[0103] Furthermore, when the control circuit 10D determines that it is in the first power state, it only needs to control the first wireless communication circuit 31E to output the first audio to the first audio output device 41 and the second audio output device 42. The method of controlling the first wireless communication circuit 31E to output the first audio to the first audio output device 41 and the second audio output device 42 can be the same as the method described above. Then, the control circuit 10D can control the first output circuit 10E to output the first video included in the first video signal to the first display region D1 in the same manner as described above.

[0104] Furthermore, when the control circuit 10D determines that the power state of the system 1 has been switched from the first power state to the second power state, it determines whether the first video and audio and the second video and audio are the same video and audio, as described above, and performs the same processing as described above.

[0105] Next, an example of the flow of information processing executed by the information processing device 10 of this embodiment will be described.

[0106] 4 is a flowchart showing an example of the flow of information processing executed by the information processing device 10 of this embodiment. In FIG. 4, a situation will be described in which the control circuit 10D has acquired the first video and audio and the second video and audio as video and audio to be output to the display device 30.

[0107] The control circuit 10D determines whether the system 1 is in the second power state (step S100). If the control circuit 10D determines that the system 1 is in the second power state (step S100: Yes), the process proceeds to step S102.

[0108] In step S102, the control circuit 10D determines whether the first video and audio to be output and the second video and audio are the same video and audio (step S102).

[0109] If the control circuit 10D determines that the first video and audio and the second video and audio are the same video and audio (step S102: Yes), the control circuit 10D proceeds to step S104.

[0110] In step S104, the control circuit 10D operates the second wireless communication circuit 32E in the power saving mode (step S104). For example, the control circuit 10D outputs a control signal indicating that the second wireless communication circuit 32E is to operate in the power saving mode to the second control information input circuit 32B via the control information output circuit 10F (step S104). By the processing of step S104, the wireless communication connection between the second wireless communication circuit 32E and the second audio output device 42 is released, and the output of the second audio from the second wireless communication circuit 32E to the second audio output device 42 is stopped.

[0111] Furthermore, the control circuit 10D controls the first wireless communication circuit 31E to output the first sound to the first sound output device 41 and the second sound output device 42 (step S106). By the processing of step S106, the first sound is output from the first wireless communication circuit 31E to the first sound output device 41 and the second sound output device 42 by wireless communication.

[0112] Furthermore, control circuit 10D controls first output circuit 10E to output the first video to first display area D1, and controls second output circuit 10G to output the second video to second display area D2 (step S108). By the processing of step S108, the first video is output to first display area D1 of first display panel 31F of first display device 31, and the second video is output to second display area D2 of second display panel 32F of second display device 32.

[0113] Next, the control circuit 10D determines whether or not to end the process (step S110). For example, the control circuit 10D makes the determination in step S110 by determining whether or not an instruction signal indicating the end of the process has been received, such as through an operation instruction from a user. Alternatively, the control circuit 10D may make the determination in step S110 by determining whether or not an instruction signal indicating the cutoff of the power supply to the system 1 has been received. If a negative determination is made in step S110 (step S110: No), the process returns to step S100. If a positive determination is made in step S110 (step S110: Yes), the present routine ends.

[0114] On the other hand, if the control circuit 10D determines in step S102 that the first video and audio and the second video and audio are different video and audio (step S102: No), the process proceeds to step S112.

[0115] In step S112, the control circuit 10D determines whether the second wireless communication circuit 32E is in the power saving mode (step S112). If the control circuit 10D determines negative in step S112 (step S112: No), the process proceeds to step S116, which will be described later. If the control circuit 10D determines positive in step S112 (step S112: Yes), the process proceeds to step S114.

[0116] In step S114, the control circuit 10D controls the second wireless communication circuit 32E to cancel the power saving mode (step S114), and then the process proceeds to step S116.

[0117] In step S116, the control circuit 10D controls the first wireless communication circuit 31E to output the first audio to the first audio output device 41, and controls the second wireless communication circuit 32E to output the second audio to the second audio output device 42 (step S116). By the processing of step S116, the first audio is output from the first wireless communication circuit 31E to the first audio output device 41 via wireless communication, and the second audio is output from the second wireless communication circuit 32E to the second audio output device 42 via wireless communication.

[0118] Furthermore, control circuit 10D controls first output circuit 10E to output the first video to first display region D1, and controls second output circuit 10G to output the second video to second display region D2 (step S118). By the processing of step S118, the first video is output to first display region D1 of first display panel 31F of first display device 31, and the second video is output to second display region D2 of second display panel 32F of second display device 32. Then, the process proceeds to step S110.

[0119] On the other hand, if the determination in step S100 is negative (step S100: No), the process proceeds to step S120. In step S120, the control circuit 10D determines whether the power state of the system 1 is the first power state (step S120). If the determination in step S120 is negative (step S120: No), the process proceeds to step S110. If the determination in step S120 is positive (step S120: Yes), the process proceeds to step S122.

[0120] In step S122, the control circuit 10D controls the first wireless communication circuit 31E to output the first sound to the first sound output device 41 and the second sound output device 42 (step S122). Therefore, when the first wireless communication circuit 31E is in an ON state in which power is supplied, and the second wireless communication circuit 32E is in a first power state in which power supply is cut off and the second wireless communication circuit 32E is in an OFF state, the first sound is output from the first wireless communication circuit 31E to the first sound output device 41 and the second sound output device 42 by wireless communication.

[0121] Furthermore, the control circuit 10D controls the first output circuit 10E to output the first video included in the first video signal to the first display region D1 (step S124), and then the process proceeds to step S110.

[0122] As described above, the information processing device 10 of this embodiment includes a first output circuit 10E, a second output circuit 10G, and a control circuit 10D. The first output circuit 10E outputs the first video included in the first video and audio to the first display area D1, and outputs the first audio included in the first video and audio to the first wireless communication circuit 31E, which outputs the audio to the first audio output device 41 via wireless communication. The second output circuit 10G outputs the second video included in the second video and audio to the second display area D2, and outputs the second audio included in the second video and audio to the second wireless communication circuit 32E, which outputs the audio to the second audio output device 42 via wireless communication. If the control circuit 10D determines that the first video and audio and the second video and audio are the same video and audio, it operates the second wireless communication circuit 32E in a power-saving mode.

[0123] In this way, when the information processing device 10 of the present embodiment determines that the first video and audio and the second video and audio are the same video and audio, it places the second wireless communication circuit 32E, which outputs the second audio included in the second video and audio to the second audio output device 42 via wireless communication, in a power saving mode. This makes it possible to avoid operating both the first wireless communication circuit 31E and the second wireless communication circuit 32E, which are multiple wireless communication circuits that output audio to the audio output device 40 via wireless communication, in order to output the same audio.

[0124] Therefore, the information processing device 10 of this embodiment can reduce the power consumption of the system 1.

[0125] (Variation 1) In the above embodiment, an example was described in which, when the control circuit 10D determines that the first video audio and the second video audio are the same audio, it operates the second wireless communication circuit 32E in a power saving mode, controls the first wireless communication circuit 31E to output the first audio to the first audio output device 41 and the second audio output device 42, and controls the first video to be output to the first display area D1 and the second video to the second display area D2.

[0126] However, the control circuit 10D may further control the first wireless communication circuit 31E to operate the second wireless communication circuit 32E in a power saving mode and output the first audio to the first audio output device 41 and the second audio output device 42 when the input of either the first video and audio or the second video and audio is stopped. At this time, the control circuit 10D may also control the first video to be output to at least one of the first display area D1 and the second display area D2.

[0127] (Variation 2) In the above embodiment, an example has been described in which the first display device 33 included in the system 1 includes the first wireless communication circuit 31E, and the second display device 32 includes the second wireless communication circuit 32E. However, at least one of the first wireless communication circuit 31E and the second wireless communication circuit 32E may be provided in the information processing device 10. Furthermore, at least one of the first wireless communication circuit 31E and the second wireless communication circuit 32E may be provided in an external device, such as the display device 30, that is communicatively connected to the information processing device 10.

[0128] 5 is a schematic diagram of an example of a system 1A of this modification. The system 1A includes an information processing device 11A, a second display device 34, a first display device 33, a first audio output device 41, and a second audio output device 42.

[0129] The information processing device 11A is similar to the information processing device 10 of the above embodiment, except that it further includes a first wireless communication circuit 31E and a second wireless communication circuit 32E. In this embodiment, the first wireless communication circuit 31E of the information processing device 11A is communicatively connected to the first output circuit 10E, and the second wireless communication circuit 32E is communicatively connected to the second output circuit 10G.

[0130] The first display device 33 and the second display device 34 are examples of the display device 30. The first display device 33 is similar to the first display device 31 of the above embodiment except that it does not include the first wireless communication circuit 31E. The second display device 34 is similar to the second display device 32 of the above embodiment except that it does not include the second wireless communication circuit 32E.

[0131] As shown in FIG. 5, the information processing device 11A may be configured to include a first wireless communication circuit 31E and a second wireless communication circuit 32E.

[0132] Furthermore, the information processing device 11A may include either the first wireless communication circuit 31E or the second wireless communication circuit 32E, and the other may be provided in an external device such as a display device 30 communicably connected to the information processing device 11A.

[0133] (Variation 3) In the above embodiment, an example has been described in which the system 1 includes the first display device 31 and the second display device 32. However, the system 1 may be configured to include one or more display devices 30, or may be configured to include one display device 30.

[0134] 6 is a schematic diagram of an example of a system 1B of this modified example. The system 1B includes an information processing device 11B, a first display device 35, and an audio output device 40. The information processing device 11B and the first display device 35 are communicably connected. At least one of the information processing device 11B and the first display device 35 is communicably connected to the audio output device 40 via wireless communication.

[0135] The first display device 35 is an example of the display device 30. In this modification, the first display device 35 includes at least a display panel 30F that displays various images. Images are displayed in one display area D of the display panel 30F, or in each of the first display area D1 and the second display area D2 of the display panel 30F.

[0136] FIG. 7 is a block diagram showing an example of the functional configuration of the system 1B.

[0137] The system 1B includes an information processing device 10, a first display device 35, a first audio output device 41, and a second audio output device 42. The information processing device 10 and the first display device 35 are connected so as to be able to communicate with each other.

[0138] The first display device 35 includes a first input circuit 31A, a control information input circuit 30B, a display device control circuit 30C, a power supply 30D, a first wireless communication circuit 31E, a second wireless communication circuit 32E, and a display panel 30F.

[0139] The first input circuit 31A, the second input circuit 32A, the control information input circuit 30B, the power supply 30D, the first wireless communication circuit 31E, the second wireless communication circuit 32E, and the first display panel 31F are connected to the display device control circuit 30C so that data or signals can be exchanged.

[0140] The first input circuit 31A, the second input circuit 32A, the second wireless communication circuit 32E, and the first wireless communication circuit 31E are the same as those in the above embodiment. The control information input circuit 30B corresponds to the first control information input circuit 31B and the second control information input circuit 32B in the higher-level embodiment. The display device control circuit 30C corresponds to the first display device control circuit 31C and the second display device control circuit 32C in the above embodiment. The power supply 30D supplies power to each component of the first display device 35. The display panel 30F is a display such as a liquid crystal display or an organic EL display.

[0141] In this modification, the first display device 35 includes a first display region D1 and a second display region D2. Specifically, as shown in Fig. 6, a first video is displayed in the first display region D1 of the display panel 30F, and a second video is displayed in the second display region D2 of the display panel 30F. In this modification, as shown in Fig. 7, the second output circuit 10G of the information processing device 10 outputs the first video to the first display region D1 of the first display device 35, and outputs the second video to the second display region D2 of the first display device 35.

[0142] The display device control circuit 30C, like the second display device control circuit 32C and the first display device control circuit 31C in the above embodiment, may control the first wireless communication circuit 31E, the second wireless communication circuit 32E, and the display panel 30F in accordance with control information received from the information processing device 10.

[0143] As in the above embodiment, when the control circuit 10D of the information processing device 10 included in the system 1B determines that the first video and audio and the second video and audio are the same audio, it controls the first wireless communication circuit 31E to operate the second wireless communication circuit 32E in a power saving mode and output the first audio to the first audio output device 41 and the second audio output device 42. Furthermore, the control circuit 10D of the information processing device 10 included in the wireless LAN communication circuit 10B controls the first video to be output to the first display region D1 of the display panel 30F, and the second video to be output to the second display region D2 of the display panel 30F.

[0144] Furthermore, similarly to the above-described first modification, the control circuit 10D of the information processing device 10 included in the system 1B may further control the first wireless communication circuit 31E to operate the second wireless communication circuit 32E in a power saving mode and output the first audio to the first audio output device 41 and the second audio output device 42 when the input of either the first video and audio or the second video and audio is stopped. At this time, the control circuit 10D may also control the first video to be output to the display area D of the display panel 30F.

[0145] (Variation 4) In the above-described modification example 3, the first display device 35 included in the system 1B is provided with the first wireless communication circuit 31E and the second wireless communication circuit 32E. However, at least one of the first wireless communication circuit 31E and the second wireless communication circuit 32E may be provided in the information processing device 10.

[0146] 8 is a schematic diagram of an example of a system 1C of this modified example. The system 1C includes an information processing device 11C, a first display device , a first audio output device 41, and a second audio output device .

[0147] The information processing device 11C is similar to the information processing device 10 of the above-described modified example 3, except that it further includes a first wireless communication circuit 31E and a second wireless communication circuit 32E. In this modified example, the first wireless communication circuit 31E of the information processing device 11C is communicatively connected to the first output circuit 10E, and the second wireless communication circuit 32E is communicatively connected to the second output circuit 10G.

[0148] The first display device 36 is an example of the display device 30. The first display device 36 is similar to the first display device 35 of the above-described third modification, except that the first display device 36 does not include the first wireless communication circuit 31E and the second wireless communication circuit 32E.

[0149] As shown in FIG. 8, an information processing device 11C may have a configuration including a first wireless communication circuit 31E and a second wireless communication circuit 32E.
