Furthermore, the program executed by the information processing device 10 and the display device 30 may also be provided as a file that can be installed on or executed within the information processing device 10 and the display device 30, recorded on a computer-readable recording medium such as a CD-ROM, floppy disk (FD), CD-R, or DVD (Digital Versatile Disc).

[0036] Next, System 1 will be described in detail.

[0037] Figure 3 This is a block diagram illustrating an example of the functional structure of System 1.

[0038] System 1 includes an information processing device 10, a second display device 32, a first display device 31, a first sound output device 41, and a second sound output device 42. The information processing device 10 is connected to the first display device 31 and the second display device 32 in a communicative manner.

[0039] First, the first display device 31 and the second display device 32 will be described.

[0040] 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.

[0041] 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 in a manner capable of transmitting data or signals.

[0042] 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 the first image sound from the first output circuit 10E of the information processing device 10 and outputs the first image sound to the first display device control circuit 31C. The first image sound is an example of an image sound.

[0043] The first control information input circuit 31B is connected to the control information output circuit 10F of the information processing device 10 in a communicable manner. The first control information input circuit 31B receives various control information output by the control circuit 10D from the control information output circuit 10F, and outputs the various control information to the first display device control circuit 31C.

[0044] The first power supply 31D supplies power to each part of the first display device 31. The first power supply 31D is configured to switch between supplying power to each part of the first display device 31 or cutting off the power supply based on user operation instructions, control information received from the information processing device 10, etc.

[0045] The first wireless communication circuit 31E outputs sound to the sound output device 40 via wireless communication. The first wireless communication circuit 31E and the sound output device 40, which is capable of Bluetooth communication, conduct Bluetooth-based communication.

[0046] The first wireless communication circuit 31E supports at least one of a multicast protocol and a broadcast protocol, and performs multicast audio transmission and reception (two-way communication) and broadcast audio transmission and reception via wireless communication. Additionally, the first wireless communication circuit 31E is capable of receiving signals from multiple audio output devices 40.

[0047] The first wireless communication circuit 31E communicates wirelessly with the audio output device 40 via Bluetooth LE (Low Power) audio. Bluetooth LE audio refers to a Bluetooth audio standard that enables simultaneous Bluetooth communication with multiple audio output devices 40. Therefore, the first wireless communication circuit 31E is configured to perform one-to-many wireless communication with multiple audio output devices 40.

[0048] In this embodiment, in the initial state, the first wireless communication circuit 31E outputs sound to the first sound output device 41 via wireless communication under the control of the first display device control circuit 31C. Additionally, the first wireless communication circuit 31E also outputs sound to the first sound output device 41 and the second sound 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.

[0049] Furthermore, in this embodiment, the following example will be used: the first wireless communication circuit 31E uses a multicast protocol to output sound to the audio output device 40 via multicast. Therefore, it will be described 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. Alternatively, the first wireless communication circuit 31E may also use a broadcast protocol to output sound to the audio output device 40 via broadcast.

[0050] The first display panel 31F is a liquid crystal display, an organic EL (electro-Luminescence) display, or the like. In this embodiment, an image is displayed in the first display area D1 of the first display panel 31F (see also [reference]). Figure 1 The first display area D1 is an example of display area D, and is the area where the image is displayed. Display area D is sometimes also referred to as the display screen.

[0051] The first display device control circuit 31C controls at least one of the first display panel 31F and the first wireless communication circuit 31E based on control information received from the information processing device 10. For example, the first display device control circuit 31C outputs a first image contained in a first image sound received from the first output circuit 10E via the first input circuit 31A to the first display area D1 of the first display panel 31F based on the control information. Additionally, the first display device control circuit 31C controls the first wireless communication circuit 31E based on the control information to output a first sound contained in a first image sound received from the first output circuit 10E via the first input circuit 31A to the sound output device 40. Details of the control performed by the first display device control circuit 31C will be described later.

[0052] The second display device 32 is an example of the display device 30. The second display device 32 is a display device 30 that is constructed separately from the first display device 31, and has the same structure as the first display device 31.

[0053] 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.

[0054] 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 in a manner capable of transmitting data or signals.

[0055] 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 the second image sound from the second output circuit 10G of the information processing device 10 and outputs the second image sound to the second display device control circuit 32C. The second image sound is an example of an image sound.

[0056] The second control information input circuit 32B is connected to the control information output circuit 10F of the information processing device 10 in a communicable manner. The second control information input circuit 32B receives various control information output by the control circuit 10D from the control information output circuit 10F, and outputs the various control information to the control circuit 32C of the second display device.

[0057] The second power supply 32D supplies power to various parts of the second display device 32. The second power supply 32D is configured to switch between supplying power to various parts of the second display device 32 or cutting off the power supply based on user operation instructions, control information received from the information processing device 10, etc.

[0058] The second wireless communication circuit 32E outputs sound to the sound output device 40 via wireless communication. Similar to the first wireless communication circuit 31E, the second wireless communication circuit 32E conducts Bluetooth-based communication with the sound output device 40, which is capable of Bluetooth communication.

[0059] Similar to the first wireless communication circuit 31E, the second wireless communication circuit 32E supports at least one of a multicast protocol and a broadcast protocol. The second wireless communication circuit 32E performs the transmission and reception of multicast audio and broadcast audio via wireless communication. Furthermore, the second wireless communication circuit 32E is capable of receiving signals from multiple audio output devices 40.

[0060] Similar to the first wireless communication circuit 31E, the second wireless communication circuit 32E communicates wirelessly with the audio output device 40 via Bluetooth LE audio. Therefore, the second wireless communication circuit 32E is configured to perform one-to-many wireless communication with multiple audio output devices 40.

[0061] In this embodiment, in the initial state, the second wireless communication circuit 32E outputs sound to the second sound output device 42 via wireless communication under the control of the second display device control circuit 32C. Additionally, the second wireless communication circuit 32E is switched to a power-saving mode under the control of the second display device control circuit 32C.

[0062] Power-saving mode refers to a mode in which at least sound output is stopped. The second wireless communication circuit 32E, switched to power-saving mode, is in a state where wireless communication is stopped. The second display device control circuit 32C controls the second wireless communication circuit 32E by stopping sound output to the sound output device 40, or by cutting off the power supply 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 power-saving mode.

[0063] Furthermore, in this embodiment, the following example will be used: similarly to the first wireless communication circuit 31E, the second wireless communication circuit 32E uses a multicast protocol to output sound to the audio output device 40 via multicast. In this embodiment, it is assumed that the second wireless communication circuit 32E is at least pre-paired with the second audio output device 42. Alternatively, the second wireless communication circuit 32E may also use a broadcast protocol to output sound to the audio output device 40 via broadcast.

[0064] The second display panel 32F is a display such as a liquid crystal display (LCD) 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 [reference]). Figure 1 The second display area D2 is an example of display area D, and is the area where the image is displayed.

[0065] The second display device control circuit 32C controls at least one of the second display panel 32F and the second wireless communication circuit 32E based on control information received from the information processing device 10. For example, the second display device control circuit 32C outputs a second image contained in a second image / sound 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 based on the control information. Additionally, the second display device control circuit 32C controls the second wireless communication circuit 32E based on the control information to output a second sound contained in a second image / sound received from the second output circuit 10G via the second input circuit 32A to the second sound output device 42. Furthermore, the second display device control circuit 32C causes the second wireless communication circuit 32E to operate in a power-saving mode based on the control information. Details of the control performed by the second display device control circuit 32C will be described later.

[0066] Next, the information processing apparatus 10 of this embodiment will be described in detail.

[0067] 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.

[0068] The wired LAN communication circuit 10A connects to the Internet via a gateway or similar device, and transmits and receives video and audio data with a server. Additionally, the wired LAN communication circuit 10A connects to an STB (Set-Top Box) or similar device, and receives video and audio from the STB, including cable broadcasts, satellite broadcasts, terrestrial television broadcasts, IP (Internet Protocol) broadcasts (broadband), and VOD (Video On Demand).

[0069] The wireless LAN communication circuit 10B transmits and receives data with wireless communication devices such as smartphones and tablets. Additionally, the wireless LAN communication circuit 10B can also connect to the Internet via an access point.

[0070] The external device connection circuit 10C communicates with external devices wirelessly or via wired connection. External devices, for example, refer to devices that transmit and receive video signals in an uncompressed manner via HDMI (High-Definition Multimedia Interface) (registered trademark), such as personal computers, projectors, and home theater equipment.

[0071] The first output circuit 10E is connected one-to-one with the first input circuit 31A of the first display device 31, and outputs a first image and sound to the first display device 31. The second output circuit 10G is connected one-to-one with the second input circuit 32A of the second display device 32, and outputs a second image and sound to the second display device 32. The first image and sound and the second image and sound are examples of image and sound.

[0072] The control information output circuit 10F outputs control information to the display device 30 under the control of the control circuit 10D.

[0073] The control circuit 10D performs various information processing operations in the information processing device 10. For example, the control circuit 10D implements the various functional units of the processing unit 20 described later on the computer by having the CPU 11D read the program from the ROM 11E and execute the program on the RAM 11F.

[0074] Part or all of the control circuit 10D can be implemented either by software, such as by a processing device like a CPU 11D executing a program, or by hardware, such as an IC (Integrated Circuit), or by a combination of software and hardware. Alternatively, it can be configured such that at least one of the functional units that perform processing in 20D is mounted on an external information processing device that is communicatively connected to the information processing device 10 via a network or the like.

[0075] The control circuit 10D acquires multiple video and audio signals intended for 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. Alternatively, the control circuit 10D may also acquire multiple video and audio signals intended for output to the display device 30 from the storage unit provided in the information processing device 10. In this embodiment, the following method will be described as an example: the control circuit 10D acquires a first video and audio signal and a second video and audio signal as video and audio signals intended for output to the display device 30.

[0076] The control circuit 10D outputs the first image and sound to the first output circuit 10E. The first output circuit 10E outputs the first image contained in the first image and sound to the first display area D1, and outputs the first sound contained in the first image and sound to the first wireless communication circuit 31E.

[0077] Additionally, the control circuit 10D outputs the second image and sound to the second output circuit 10G. The second output circuit 10G outputs the second image contained in the second image and sound to the second display area D2, and outputs the second sound contained in the second image and sound to the second wireless communication circuit 32E.

[0078] The control circuit 10D determines whether the sound of the first image and the sound of the second image are the same. The control circuit 10D can determine whether the two image sounds are the same using a known method.

[0079] When the control circuit 10D determines that the first image sound and the second image sound are the same, it causes the second wireless communication circuit 32E to operate in a power-saving mode. Specifically, the control circuit 10D outputs a control signal indicating that the second wireless communication circuit 32E should operate in a power-saving mode to the second control information input circuit 32B via the control information output circuit 10F.

[0080] The second display device control circuit 32C, 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 power-saving mode. Specifically, upon receiving the control signal, the second display device control circuit 32C controls the second wireless communication circuit 32E by stopping the output of sound to the sound output device 40, or by cutting off the power supply 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 power-saving mode.

[0081] By activating the second wireless communication circuit 32E in power-saving mode, the wireless communication connection between the second wireless communication circuit 32E and the second sound output device 42 is disconnected, and the output of the second sound from the second wireless communication circuit 32E to the second sound output device 42 is stopped.

[0082] Then, the control circuit 10D controls the first wireless communication circuit 31E in such a way that it outputs the first sound contained in the first image sound to the first sound output device 41 and the second sound output device 42.

[0083] Therefore, when it is determined that the first image sound and the second image sound are the same image sound, the second wireless communication circuit 32E is switched to power saving mode, and 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.

[0084] Here, priority order information indicating the priority of the wireless communication circuits of the objects to be connected to the wireless communication may also be pre-registered in the first sound output device 41 and the second sound output device 42, respectively.

[0085] In this embodiment, in the first sound output device 41, wireless communication circuit identification information for identifying the first wireless communication circuit 31E is pre-registered corresponding to the first priority information indicating the highest priority order "1". Additionally, in the first sound output device 41, wireless communication circuit identification information for identifying the second wireless communication circuit 32E is pre-registered corresponding to the second priority information indicating the next priority order "2".

[0086] Furthermore, in the second sound output device 42, wireless communication circuit identification information for identifying the second wireless communication circuit 32E is pre-registered corresponding to the first priority information indicating the highest priority order "1". Additionally, in the second sound output device 42, wireless communication circuit identification information for identifying the first wireless communication circuit 31E is pre-registered corresponding to the second priority information indicating the next priority order "2".

[0087] First priority information and second priority information are examples of priority information.

[0088] Then, if the first sound output device 41 and the second sound output device 42 are able to receive sound from the first wireless communication circuit 31E and the second wireless communication circuit 32E respectively via wireless communication, they will receive and output sound from the wireless communication circuit with higher priority. Alternatively, if the first sound output device 41 and the second sound output device 42 are unable to receive sound from the wireless communication circuit with the highest priority, they will receive sound from the wireless communication circuit with the next highest priority.

[0089] Assume that the second wireless communication circuit 32E enters a power-saving mode and stops outputting the second sound wirelessly. In this case, the second sound output device 42 becomes unable to receive the second sound from the second wireless communication circuit 32E, which is identified based on wireless communication circuit identification information corresponding to higher priority information. In other words, the second sound output device 42 becomes in a state where it stops receiving the second sound from the second wireless communication circuit 32E, which is identified based on wireless communication circuit identification information corresponding to the highest priority information "1".

[0090] In this case, the second sound output device 42 receives the first sound from the first wireless communication circuit 31E, which is identified according to wireless communication circuit identification information corresponding to a lower priority information. Specifically, the second sound output device 42 receives and outputs the first sound from the first wireless communication circuit 31E, which is identified according to wireless communication circuit identification information corresponding to a second priority information "2" of the next priority order.

[0091] Therefore, when priority information is pre-registered in the sound output device 40, the control circuit 10D can control the first wireless communication circuit 31E to output the first sound contained in the first image sound to the first sound output device 41 and the second sound output device 42 by enabling the second wireless communication circuit 32E to operate in a power-saving mode. That is, when priority information is pre-registered in the sound output device 40, the control circuit 10D can control the first wireless communication circuit 31E to output the first sound contained in the first image sound to the first sound output device 41 and the second sound output device 42 through simple control.

[0092] Alternatively, it can be done in a manner where priority order information indicating the priority of the wireless communication circuits of the objects to be connected to the wireless communication is not pre-registered in each of the first sound output devices 41 and the second sound output devices 42.

[0093] In this case, when the control circuit 10D determines that the first image sound and the second image sound are the same image sound, it causes the second wireless communication circuit 32E to operate in a power-saving mode and sends control information to the first display device 31 to control 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.

[0094] In detail, before determining that the first image and the second image are the same image (i.e., in the initial state), the control circuit 10D controls the first wireless communication circuit 31E to output the first sound only to the first sound output device 41 as the output destination. Additionally, the control circuit 10D controls the second wireless communication circuit 32E to output the second sound only to the second sound output device 42 as the output destination.

[0095] Then, when the control circuit 10D determines that the first image sound and the second image sound are the same image sound, it controls the first wireless communication circuit 31E to output the first sound to both the first sound output device 41 and the second sound output device 42 as output destinations.

[0096] Alternatively, the first wireless communication circuit 31E and the second wireless communication circuit 32E can both use multicast and broadcast protocols, enabling them to output sound to the audio output device 40 via multicast or broadcast. In this case, before determining that the first image and the second image are the same image (i.e., in the initial state), the control circuit 10D controls the first wireless communication circuit 31E to output the first audio only to the first audio output device 41 via multicast. Furthermore, the control circuit 10D controls the second wireless communication circuit 32E to output the second audio only to the second audio output device 42 via multicast. Moreover, if the control circuit 10D determines that the first image audio and the second image audio are the same image 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 via broadcast.

[0097] Through these controls, when the control circuit 10D determines that the first image sound and the second image sound are the same image sound, it causes the second wireless communication circuit 32E to operate in a power-saving mode and 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.

[0098] Furthermore, the control circuit 10D controls the first output circuit 10E to output the first image to the first display area D1, and controls the second output circuit 10G to output the second image to the second display area D2. That is, the first output circuit 10E outputs the first image to the first display area D1 of one or more display devices 30, and the second output circuit 10G outputs the second image to the second display area D2 of one or more display devices 30.

[0099] In this embodiment, the first output circuit 10E outputs the first image to the first display area D1 of the first display panel 31F of the first display device 31. Additionally, the second output circuit 10G outputs the second image to the second display area D2 of the second display panel 32F of the second display device 32 (see also...). Figure 1 ).

[0100] In detail, when the first display device control circuit 31C of the first display device 31 receives the first image and sound from the first output circuit 10E of the information processing device 10 via the first input circuit 31A, it outputs the first image contained in the first image and sound to the first display area D1 of the first display panel 31F. Similarly, when the second display device control circuit 32C of the second display device 32 receives the second image and sound from the first output circuit 10E via the second input circuit 32A, it outputs the second image contained in the second image and sound to the second display area D2 of the second display panel 32F. Therefore, as... Figure 1 As shown, a first image is displayed in a first display area D1 of the first display panel 31F, and a second image is displayed in a second display area D2 of the second display panel 32F. Furthermore, if the sound of the first image and the sound of the second image are the same, the same image is displayed in both the first display area D1 and the second display area D2.

[0101] On the other hand, when the control circuit 10D determines that the first image sound and the second image sound are different image sounds, it controls the first wireless communication circuit 31E to output the first sound to the first sound output device 41, and controls the second wireless communication circuit 32E to output the second sound to the second sound output device 42.

[0102] When the control circuit 10D determines that the first image sound and the second image sound are different image sounds and determines that the second wireless communication circuit 32E is in power saving mode, after controlling the second wireless communication circuit 32E to deactivate the power saving mode, it controls the second wireless communication circuit 32E to output the second sound to the second sound output device 42.

[0103] Similarly, it is assumed that the first audio output device 41 and the second audio output device 42 each have priority order information indicating the priority of the wireless communication circuits of the objects to be connected via wireless communication pre-registered. Similarly, it is assumed that in the first audio output device 41, wireless communication circuit identification information for identifying the first wireless communication circuit 31E is registered corresponding to the first priority order information, and wireless communication circuit identification information for identifying the second wireless communication circuit 32E is pre-registered corresponding to the second priority order information, which is the next priority order. Furthermore, it is assumed that in the second audio output device 42, wireless communication circuit identification information for identifying the second wireless communication circuit 32E is registered corresponding to the first priority order information, and wireless communication circuit identification information for identifying the first wireless communication circuit 31E is pre-registered corresponding to the second priority order information, which is the next priority order.

[0104] In this case, when the power-saving mode of the second wireless communication circuit 32E is deactivated and the second sound is output wirelessly from the second wireless communication circuit 32E, the second sound output device 42 receives the second sound from the second wireless communication circuit 32E, which is identified based on wireless communication circuit identification information corresponding to higher priority information. Meanwhile, the first sound output device 41 receives the first sound from the first wireless communication circuit 31E, which is identified based on wireless communication circuit identification information corresponding to higher priority information.

[0105] Therefore, when priority information is pre-registered in the sound output device 40, the control circuit 10D can deactivate the power-saving mode of the second wireless communication circuit 32E, thereby controlling the first wireless communication circuit 31E to output the first sound contained in the first image sound to the first sound output device 41, and controlling the second wireless communication circuit 32E to output the second sound contained in the second image sound to the second sound output device 42. That is, when priority information is pre-registered in the sound output device 40, the control circuit 10D can easily control the first wireless communication circuit 31E to output the first sound to the first sound output device 41, and control the second wireless communication circuit 32E to output the second sound to the second sound output device 42.

[0106] Alternatively, similarly to the above, it is also possible that no priority order information indicating the priority of the wireless communication circuits of the objects to be connected to the wireless communication is pre-registered in each of the first sound output devices 41 and the second sound output devices 42.

[0107] In this case, when the control circuit 10D determines that the first image sound and the second image sound are different image sounds, it sends control information to the first display device 31 and the second display device 32 respectively to control the output of the first sound from the first wireless communication circuit 31E to the first sound output device 41 and the output of the second sound from the second wireless communication circuit 32E to the second sound output device 42.

[0108] In detail, the control circuit 10D sends a control signal to the first display device 31 via the control information output circuit 10F, indicating that the first sound output device 41 is the only output destination and that the first sound is output to the first sound output device 41. The first display device control circuit 31C, receiving this control signal via the first control information input circuit 31B, controls the first wireless communication circuit 31E to output the first sound only to the first sound output device 41. Additionally, the control circuit 10D sends a control signal to the second display device 32 via the control information output circuit 10F, indicating that the second sound output device 42 is the only output destination and that the second sound is output to the second sound output device 42. The second display device control circuit 32C, receiving this control signal via the second control information input circuit 32B, controls the second wireless communication circuit 32E to output the second sound only to the second sound output device 42.

[0109] Through these controls, when the control circuit 10D determines that the first image sound and the second image sound are different image sounds, it controls the first wireless communication circuit 31E to output the first sound to the first sound output device 41, and controls the second wireless communication circuit 32E to output the second sound to the second sound output device 42.

[0110] Then, the control circuit 10D controls the first output circuit 10E to output the first image to the first display area D1, and controls the second output circuit 10G to output the second image to the second display area D2. That is, the first output circuit 10E outputs the first image to the first display area D1 of the first display device 31, and the second output circuit 10G outputs the second image to the second display area D2 of the second display device 32. Therefore, as... Figure 1 As shown, a first image is displayed in a first display area D1 of the first display panel 31F, and a second image is displayed in a second display area D2 of the second display panel 32F. Furthermore, if the audio of the first image and the audio of the second image are different, different images are displayed in the first display area D1 and the second display area D2.

[0111] In addition, the control circuit 10D can also determine whether the system 1 is in the first power state or the second power state. If the system 1 is determined to be in the first power state, it can determine whether the first image sound and the second image sound are the same image sound.

[0112] The first power state refers to the state where the first wireless communication circuit 31E is powered on and the second wireless communication circuit 32E is powered off. In this embodiment, the following example will be used: 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. Therefore, in this embodiment, it will be assumed that the first power state represents the case where the first display device 31 is powered on and the second display device 32 is powered off.

[0113] The second power state refers to the state in which both the first wireless communication circuit 31E and the second wireless communication circuit 32E are powered on. In this embodiment, the following example will be used for explanation: 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. Therefore, in this embodiment, it will be explained as if the second power state refers to the state in which both the first display device 31 and the second display device 32 are powered on.

[0114] For example, the control circuit 10D sends control information indicating the power supply status to the first display device 31 and the second display device 32 via the control information output circuit 10F. Then, the control circuit 10D receives a response signal indicating an on state from the first display device 31 within a specified time in response to the control information. If no response signal indicating an on state is received from the second display device 32 within the specified time, or if a response signal indicating an off state is received, it is determined that the power supply is in the first power state.

[0115] Alternatively, for example, the control circuit 10D sends control information indicating the power supply status to the first display device 31 and the second display device 32 via the control information output circuit 10F. Then, 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 if it receives a response signal indicating an on state from the second display device 32 within the predetermined time, it determines that it is a second power state.

[0116] When the control circuit 10D determines that it is in the second power state, it determines whether the first image sound and the second image sound are the same image sound and performs the same processing as described above.

[0117] Furthermore, when the control circuit 10D determines that the first power state is active, it 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. The method for controlling 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 can be the same as described above. Then, the control circuit 10D controls the first output circuit 10E in the same way as described above to output the first image contained in the first image sound to the first display area D1.

[0118] In addition, when the control circuit 10D determines that the power state of the system 1 has switched from the first power state to the second power state, it can determine whether the first image sound and the second image sound are the same image sound and perform the same processing as described above.

[0119] Next, an example of the information processing flow performed by the information processing apparatus 10 of this embodiment will be described.

[0120] Figure 4 This is a flowchart illustrating an example of the information processing flow performed by the information processing apparatus 10 of this embodiment. Figure 4 In this case, we will describe a scenario where the control circuit 10D acquires the first image sound and the second image sound as the image sound to be output to the display device 30.

[0121] The control circuit 10D determines whether system 1 is in the second power state (step S100). When it is determined that system 1 is in the second power state (step S100: "Yes"), proceed to step S102.

[0122] In step S102, the control circuit 10D determines whether the first image sound and the second image sound of the output object are the same image sound (step S102).

[0123] When the control circuit 10D determines that the first image sound and the second image sound are the same image sound (step S102: "Yes"), it proceeds to step S104.

[0124] In step S104, the control circuit 10D causes the second wireless communication circuit 32E to operate in power-saving mode (step S104). For example, the control circuit 10D outputs a control signal indicating that the second wireless communication circuit 32E should operate in power-saving mode to the second control information input circuit 32B via the control information output circuit 10F (step S104). Through the processing in step S104, the wireless communication connection between the second wireless communication circuit 32E and the second sound output device 42 is terminated, and the output of the second sound from the second wireless communication circuit 32E to the second sound output device 42 is stopped.

[0125] Additionally, 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). Through 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 via wireless communication.

[0126] Additionally, the control circuit 10D controls the first output circuit 10E to output the first image to the first display area D1, and controls the second output circuit 10G to output the second image to the second display area D2 (step S108). Through the processing in step S108, the first image is output to the first display area D1 of the first display panel 31F of the first display device 31, and the second image is output to the second display area D2 of the second display panel 32F of the second display device 32.

[0127] Next, the control circuit 10D determines whether to end the process (step S110). For example, the control circuit 10D performs the determination in step S110 by determining whether it has received an indication signal indicating the end of the process based on the user's operation instructions, etc. Alternatively, the control circuit 10D may also perform the determination in step S110 by determining whether it has received an indication signal indicating the cutting off of power supply to system 1. When a negative determination is made in step S110 (step S110: "No"), the process returns to step S100. When a positive determination is made in step S110 (step S110: "Yes"), the routine ends.

[0128] On the other hand, in step S102 above, when the control circuit 10D determines that the first image sound and the second image sound are different image sounds (step S102: "No"), it proceeds to step S112.

[0129] In step S112, the control circuit 10D determines whether the second wireless communication circuit 32E is in power-saving mode (step S112). If the control circuit 10D makes a negative judgment in step S112 (step S112: "No"), it proceeds to step S116 as described later. If the control circuit 10D makes a positive judgment in step S112 (step S112: "Yes"), it proceeds to step S114.

[0130] In step S114, the control circuit 10D controls the second wireless communication circuit 32E to deactivate its power-saving mode (step S114). Then, proceed to step S116.

[0131] In step S116, the control circuit 10D controls the first wireless communication circuit 31E to output a first sound to the first sound output device 41, and controls the second wireless communication circuit 32E to output a second sound to the second sound output device 42 (step S116). Through the processing of step S116, the first sound is output wirelessly from the first wireless communication circuit 31E to the first sound output device 41, and the second sound is output wirelessly from the second wireless communication circuit 32E to the second sound output device 42.

[0132] Additionally, the control circuit 10D controls the first output circuit 10E to output the first image to the first display area D1, and controls the second output circuit 10G to output the second image to the second display area D2 (step S118). Through the processing in step S118, the first image is output to the first display area D1 of the first display panel 31F of the first display device 31, and the second image is output to the second display area D2 of the second display panel 32F of the second display device 32. Then, the process proceeds to step S110.

[0133] On the other hand, if a negative judgment is made in step S100 (step S100: "No"), proceed to step S120. In step S120, the control circuit 10D determines whether the power state of system 1 is the first power state (step S120). When a negative judgment is made in step S120 (step S120: "No"), proceed to step S110. When a positive judgment is made in step S120 (step S120: "Yes"), proceed to step S122.

[0134] In step S122, the control circuit 10D controls the first wireless communication circuit 31E to output a 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 a powered-on state and the second wireless communication circuit 32E is in a powered-off state, i.e., a first power state, the first sound is output wirelessly from the first wireless communication circuit 31E to the first sound output device 41 and the second sound output device 42.

[0135] Additionally, the control circuit 10D controls the first output circuit 10E to output the first image contained in the first image sound to the first display area D1 (step S124). Then, proceed to step S110.

[0136] As described above, the information processing apparatus 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 a first image contained in a first image sound to a first display area D1, and outputs a first sound contained in the first image sound to a first wireless communication circuit 31E, which outputs sound to a first sound output device 41 via wireless communication. The second output circuit 10G outputs a second image contained in a second image sound to a second display area D2, and outputs a second sound contained in the second image sound to a second wireless communication circuit 32E, which outputs sound to a second sound output device 42 via wireless communication. When the control circuit 10D determines that the first image sound and the second image sound are the same image sound, it causes the second wireless communication circuit 32E to operate in a power-saving mode.

[0137] In this way, when the information processing apparatus 10 of this embodiment determines that the first image sound and the second image sound are the same image sound, it puts the second wireless communication circuit 32E, which outputs the second sound contained in the second image sound to the second sound output device 42 via wireless communication, into a power-saving mode. Therefore, it is possible to avoid both the first wireless communication circuit 31E and the second wireless communication circuit 32E, which output sound to the sound output device 40 via wireless communication, operating in order to output the same sound.

[0138] Therefore, the information processing device 10 of this embodiment can reduce the power consumption of system 1.

[0139] (Variation Example 1)

[0140] In the above embodiment, the following method is described as an example: when the control circuit 10D determines that the first image sound and the second image sound are the same image sound, it causes the second wireless communication circuit 32E to operate in a power-saving mode, and 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, and controls the output of the first image to the first display area D1 and the second image to the second display area D2.

[0141] However, the control circuit 10D can also, even when the input of either the first image / sound or the second image / sound is stopped, cause the second wireless communication circuit 32E to operate in a power-saving mode, and control 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. Alternatively, at this time, the control circuit 10D can also control the output of the first image to at least one of the first display area D1 and the second display area D2.

[0142] (Variation Example 2)

[0143] In the above embodiment, the following example is provided: the first display device 33 included in system 1 includes a first wireless communication circuit 31E, and the second display device 32 includes a second wireless communication circuit 32E. However, at least one of the first wireless communication circuit 31E and the second wireless communication circuit 32E may also be provided in the information processing device 10. In addition, 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 a display device 30 that is communicatively connected to the information processing device 10.

[0144] Figure 5 This is a schematic diagram of an example of system 1A of this modification. System 1A includes an information processing device 11A, a second display device 34, a first display device 33, a first sound output device 41, and a second sound output device 42.

[0145] The information processing device 11A also includes a first wireless communication circuit 31E and a second wireless communication circuit 32E, and is otherwise the same as the information processing device 10 described in the above embodiment. In this embodiment, the first wireless communication circuit 31E of the information processing device 11A is connected to the first output circuit 10E in a communicable manner, and the second wireless communication circuit 32E is connected to the second output circuit 10G in a communicable manner.

[0146] The first display device 33 and the second display device 34 are examples of the display device 30. The first display device 33 is the same as the first display device 31 in the above embodiment except that it does not have the first wireless communication circuit 31E. The second display device 34 is the same as the second display device 32 in the above embodiment except that it does not have the second wireless communication circuit 32E.

[0147] like Figure 5 As shown, the information processing device 11A may also have a structure that includes a first wireless communication circuit 31E and a second wireless communication circuit 32E.

[0148] Alternatively, the information processing device 11A may include either a first wireless communication circuit 31E or a second wireless communication circuit 32E, with the other being disposed in an external device such as a display device 30 that is communicatively connected to the information processing device 11A.

[0149] (Variation Example 3)

[0150] In the above embodiment, the following example is provided: System 1 includes a first display device 31 and a second display device 32. However, System 1 may have one or more display devices 30, or it may have only one display device 30.

[0151] Figure 6 This is a schematic diagram of an example of system 1B of this modification. System 1B includes an information processing device 10, a first display device 35, and a sound output device 40. The information processing device 10 and the first display device 35 are connected in a communicable manner. At least one of the information processing device 10 and the first display device 35 is connected to the sound output device 40 in a manner that enables wireless communication.

[0152] The first display device 35 is an example of the display device 30. In this modified example, the first display device 35 includes at least a display panel 30F for displaying various images. Images are displayed in a display area D of the display panel 30F, or images are displayed in a first display area D1 and a second display area D2 of the display panel 30F respectively.

[0153] Figure 7 This is a block diagram illustrating an example of the functional structure of system 1B.

[0154] System 1B includes an information processing device 10, a first display device 35, a first sound output device 41, and a second sound output device 42. The information processing device 10 and the first display device 35 are connected in a communicative manner.

[0155] 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.

[0156] 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 in a manner capable of transmitting data or signals.

[0157] 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 in the above embodiment. The control information input circuit 30B is equivalent to the first control information input circuit 31B and the second control information input circuit 32B in the above embodiment. The display device control circuit 30C is equivalent 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 part of the first display device 35. The display panel 30F is a display such as a liquid crystal display or an organic EL display.

[0158] In this modified example, the first display device 35 includes a first display area D1 and a second display area D2. More specifically, as... Figure 6 As shown, a first image is displayed in the first display area D1 of the display panel 30F, and a second image is displayed in the second display area D2 of the display panel 30F. In this modified example, as... Figure 7 As shown, the second output circuit 10G of the information processing device 10 outputs the first image to the first display area D1 of the first display device 35 and outputs the second image to the second display area D2 of the first display device 35.

[0159] Similar to the second display device control circuit 32C and the first display device control circuit 31C in the above embodiments, the display device control circuit 30C controls the first wireless communication circuit 31E, the second wireless communication circuit 32E, and the display panel 30F according to the control information received from the information processing device 10.

[0160] In the same manner as in the above embodiment, when the control circuit 10D of the information processing device 10 in system 1B determines that the first image sound and the second image sound are the same, it causes the second wireless communication circuit 32E to operate in power-saving mode and 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. Furthermore, the control circuit 10D of the information processing device 10 in system 1B controls the output of the first image to the first display area D1 of the display panel 30F and the output of the second image to the second display area D2 of the display panel 30F.

[0161] Furthermore, similar to the modified example 1, the control circuit 10D of the information processing device 10 included in system 1B can also, when the input of either the first image sound or the second image sound is stopped, cause the second wireless communication circuit 32E to operate in a power-saving mode, and control 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. Additionally, at this time, the control circuit 10D can also control the output of the first image to the display area D of the display panel 30F.

[0162] (Variation Example 4)

[0163] In the above-described variation 3, the following example is provided: the first display device 35 included in system 1B includes a first wireless communication circuit 31E and a second wireless communication circuit 32E. However, at least one of the first wireless communication circuit 31E and the second wireless communication circuit 32E may also be provided in the information processing device 10.

[0164] Figure 8 This is a schematic diagram of an example of system 1C of this modification. System 1C includes an information processing device 11C, a first display device 36, a first sound output device 41, and a second sound output device 42.

[0165] The information processing device 11C also includes a first wireless communication circuit 31E and a second wireless communication circuit 32E, except that it is the same as the information processing device 10 in the above-described variant 3. In this variant, the first wireless communication circuit 31E of the information processing device 11C is connected to the first output circuit 10E in a communicable manner, and the second wireless communication circuit 32E is connected to the second output circuit 10G in a communicable manner.

[0166] The first display device 36 is an example of the display device 30. The first display device 36 is the same as the first display device 35 of the above-described variation 3 except that it does not have the first wireless communication circuit 31E and the second wireless communication circuit 32E.

[0167] like Figure 8 As shown, the information processing device 11C may also have a structure that includes a first wireless communication circuit 31E and a second wireless communication circuit 32E.

[0168] Alternatively, the information processing device 11C may include either a first wireless communication circuit 31E or a second wireless communication circuit 32E, with the other being disposed in a first display device 36 that is communicatively connected to the information processing device 11C.

[0169] In addition, this technology can also adopt the following structure.
