JP 2009-71657 A

  The present invention has been made to solve the above-described conventional problems, and an object thereof is to provide a receiving apparatus that can be wirelessly connected to a transmitting apparatus without requiring a user operation.

  A receiving device according to a preferred embodiment of the present invention is a receiving device that can be wirelessly connected to a transmitting device, an identification information managing means for managing identification information of one or a plurality of the transmitting devices, and a person who senses the presence of a human being A sensor for searching for the transmission device managed by the identification information management means when the presence of a human being is detected by the human sensor, and the transmission device for detecting a human presence by the human sensor Search means that does not search for, when the search means finds the transmission device, connection means for wireless connection with the found transmission device, and reception means for receiving content from the transmission device connected by the connection means, And reproducing means for reproducing the content received by the receiving means.

  The searching means searches for the transmitting device when the human sensor detects the presence of a human being, and does not search for the transmitting device when the human sensor does not detect the human presence. Therefore, since the search means does not always search for the transmission device, it is possible to prevent generation of useless power consumption in the search means. The fact that there is no person in the vicinity of the receiving device is because the receiving device does not need to receive and reproduce content from the transmitting device. When the search means searches for and finds the transmission device, the connection means wirelessly connects to the transmission device. Therefore, a person possesses a transmission device, carries it, and moves to the vicinity of the reception device. The reception device automatically connects to the transmission device possessed and carried by the person, and receives and reproduces content from the transmission device. be able to.

  In a preferred embodiment, the identification information management means manages identification information of one or a plurality of the transmission apparatuses according to a predetermined priority, and when the connection means is wirelessly connected to the transmission apparatus, the identification information management means is wirelessly connected. The management content is changed so that the priority of the transmission device becomes the highest, and the search means searches the transmission devices managed by the identification information management means in order from the highest priority, and the transmission device The search for the transmitting device is terminated when the device is found.

  In this case, the search means searches for the transmission device in order from the recently connected transmission device, and ends the search when the transmission device is found. Since the recently connected transmitter is likely to be used again by the user, the receiver can quickly find the transmitter, and wasteful search processing can be reduced.

  In a preferred embodiment, when the presence sensor is no longer detected by the human sensor, the connection means releases the connection with the transmission device.

  Even if the person who owns the transmission device goes out of the room where the reception device is located, the content is transmitted from the transmission device to the reception device within the wireless range of the reception device. Will be played continuously. Therefore, if the receiving device releases the wireless connection with the transmitting device based on whether or not the content is received, the connection cannot be released at an appropriate time. Therefore, the connection can be released at an appropriate time by releasing the wireless connection with the transmission device when the human sensor no longer senses the presence of a person.

  In a preferred embodiment, the receiving apparatus is wirelessly connectable to a transmitting apparatus, manages identification information of one or a plurality of the transmitting apparatuses according to a predetermined priority order, and a connection unit wirelessly connects to the transmitting apparatus The identification information management means for changing the management contents so that the priority of the wirelessly connected transmission device is highest, and the transmission devices managed by the identification information management means are searched in order from the highest priority And searching means for ending the search for the transmitting device when the transmitting device is found, the connecting means for wirelessly connecting to the found transmitting device when the searching means finds the transmitting device, and the connection Receiving means for receiving content from a transmission device connected by the means, and playback means for playing back the content received by the receiving means.

  The search means searches for a transmission device in order from the recently connected transmission device, and ends the search when the transmission device is found. Since the recently connected transmitter is highly likely to be used by the user, the transmitter can be quickly found.

  In a preferred embodiment, the identification information management means has a predetermined number of items capable of registering a predetermined number of the identification information of the transmission devices, and is wirelessly connected when the connection means is wirelessly connected to the transmission device. The identification information of the transmitting device is moved or newly registered to the item with the highest priority, and the identification information of the other transmitting devices is moved in the item so that the priority is lowered one by one.

  In this case, the transmission device can be managed in the order of the time when it was last connected to the reception device only by managing on the memory a predetermined number of items that can register the identification information of the predetermined number of transmission devices. . Therefore, management in the memory is very simple, and the memory capacity can be reduced.

  In a preferred embodiment, the information processing apparatus further includes instruction means for transmitting a reproduction application program start instruction and a content reproduction instruction to the transmission apparatus connected by the connection means when the connection means is wirelessly connected to the transmission apparatus.

  Even when the playback application is not activated or the content is not played back on the transmission device, the playback device plays the content without requiring a user operation, and the reception device receives the content from the transmission device Can do.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to these embodiments.

  FIG. 1 is a schematic block diagram showing a content reproduction system according to a preferred embodiment of the present invention. The content reproduction system includes a content receiving device (hereinafter referred to as a receiving device) 100 and a content transmitting device (hereinafter referred to as a transmitting device) 200. The receiving device 100 is, for example, a stationary audio device installed in each room. The transmission device 200 is a music player, laptop computer, smartphone, mobile phone, portable game machine, etc. that each individual has and carries. The content is a general term for music files (music data), audio files (audio data), video files (video data), still image files (still image data), etc., but in this embodiment, music files (music data). It is.

  The receiving device 100 and the transmitting device 200 can be connected to each other by wireless communication of any standard such as Bluetooth. The transmission device 200 reproduces the music file recorded by itself, and transmits the reproduced music data to the reception device 100 via wireless. The receiving device 100 receives and amplifies the music data transmitted from the transmitting device 200, and outputs sound from the speaker.

  The receiving apparatus 100 generally includes a CPU 1, a rewritable memory 2 such as a RAM or a flash memory, a ROM 3, a communication unit 4, a reproduction unit 5, a speaker 6, and a human sensor 7. The CPU 1 controls each unit of the receiving device 100 based on the operation program of the receiving device 100 stored in the ROM 3.

  The communication unit 4 is connected to and communicates with the communication unit 18 of the transmission device 200 and transmits / receives various control commands, music data, and the like to / from the transmission device 200. The communication unit 4 is, for example, a Bluetooth radio transceiver. The reproduction unit 5 reproduces the music data received by the communication unit 4 from the transmission device 200 (for example, decoding, D / A conversion, volume adjustment, amplification, etc.), and outputs sound from the speaker 6.

  The human sensor 7 detects the presence of a human and notifies the CPU 1 of the result. As the human sensor 7, a known sensor such as an infrared ray, an ultrasonic wave, or visible light can be used. When the CPU 1 searches for the transmitting device 200 and finds the transmitting device 200 when receiving a notification from the human sensor 7 that the presence of a person is detected when the receiving device 100 is not connected to the transmitting device 200 Is automatically connected to the transmission device 200. On the other hand, when the reception device 100 is not connected to the transmission device 200, the CPU 1 does not search the transmission device 200 when it does not receive a notification from the human sensor 7 that human presence has been detected. Therefore, power consumption due to a useless search of the receiving device 100 can be suppressed.

  The CPU 1 manages the identification information of one or a plurality of transmission devices 200 according to a predetermined priority order, and when the wireless device is wirelessly connected to the transmission device 200, the management content is such that the priority order of the wirelessly connected transmission device 200 is the highest. To change. The CPU 1 searches the transmission device 200 in descending order of priority, and ends the search for the transmission device 200 when the transmission device 200 is found.

  Specifically, the rewritable memory 2 stores connection history tables shown in FIGS. 2A to 2C. The connection history table is a table for managing a connection history between the receiving device 100 and the transmitting device 200. There are a predetermined number of items (eight in this example) in the connection history table, and identification information of the transmission device 200 can be registered in each item. The identification information is information that is mutually exchanged and registered when the receiving device 100 and the transmitting device 200 are paired, and is, for example, a combination of the address of the transmitting device 200 and an encryption key. 2A to 2C, the identification information of the transmission apparatus is simply abbreviated as “transmission apparatus A” or the like. In the connection history table, the item of number 1 (lower side in the figure) has a higher priority, and the priority becomes lower toward the item of number 8 (upper side in the figure). For example, in FIG. 2A, the priority order is the order of the transmission device A, the transmission device B, the transmission device C, and the transmission device D from the highest.

  When the receiving device 100 is wirelessly connected to the transmitting device 200, the CPU 1 moves (or newly registers) the identification information of the wirelessly connected transmitting device 200 to the item with the highest priority in the connection history table. The identification information of the transmission apparatus 200 is moved so that the priority order is lowered one by one.

  For example, when the receiving apparatus 100 is wirelessly connected to the transmitting apparatus C in the state of FIG. 2A, the priority order of the transmitting apparatus C is the highest and the priorities of the other transmitting apparatuses are decremented one by one as shown in FIG. 2B. It is done. 2B, when the receiving apparatus 100 newly connects to the transmitting apparatus E and executes the pairing process, as shown in FIG. 2C, the identification information of the transmitting apparatus E has the highest priority item ( Number 1) is newly registered, and the priorities of the other transmitting apparatuses 200 are lowered by one each.

  In addition, when pairing with a new transmission device 200 in a state where the identification information of the transmission device 200 is registered in all the eight items and registering the identification information of the transmission device 200, the lowest priority ( The identification information of the transmission device 200 in item 8) may be deleted from the connection history table.

  When searching for the transmission device 200, the CPU 1 first selects the transmission device 200 (the transmission device A in FIG. 2A) with the highest priority in the connection history table as a search target. The CPU 1 searches for the selected transmission device A and automatically establishes a wireless connection with the transmission device A if it can be found. On the other hand, if it cannot be found, the CPU 1 selects the transmission device 200 (transmission device B in FIG. 2A) with the next highest priority in the connection history table as a search target. The CPU 1 searches for the selected transmission device B and automatically establishes a wireless connection with the transmission device B if it can be found. Then, the CPU 1 rearranges the connection history table so that the transmission apparatus B has the highest priority.

  If necessary, the CPU 1 transmits an instruction to start a playback application program and an instruction to start playback of a music file to the wirelessly connected transmitting device 200. Accordingly, the transmission device 200 wirelessly connected to the reception device 100 can automatically start playing the music file and transmit the music data to the reception device 100 (ie, without requiring a user operation).

  The transmission device 200 includes a CPU 11, a RAM 12, a ROM 13, a content storage unit 14 such as a flash memory, a playback unit 15, a display unit 16, an operation unit 17, and a communication unit 18. The CPU 11 controls each unit of the transmission device 200 based on the operation program of the transmission device 200 stored in the ROM 13. Further, a reproduction application program is installed or recorded in the ROM 13. The CPU 11 reads the playback application program into the RAM 12 and executes it.

  A plurality of music files are recorded in the flash memory 14. The reproduction unit 15 reproduces the music file recorded in the flash memory 14 according to the reproduction application program, and transmits the music data to the receiving device 100 via the communication unit 18. The display unit 16 displays content information (music title, artist name, etc.) of the music file being played. The operation unit 17 receives an instruction based on a user operation, and is an operation button, a touch panel, or the like provided on the casing of the transmission device 200. The communication unit 18 communicates with the communication unit 4 of the receiving device 100 and transmits / receives various control commands, music data, and the like to / from the receiving device 100. The communication unit 18 is, for example, a Bluetooth wireless transceiver.

  The operation of this embodiment will be described below. FIG. 3 is a flowchart showing Bluetooth pairing processing between the receiving apparatus 100 and the transmitting apparatus 200. The receiving apparatus 100 and the transmitting apparatus 200 are connected to each other by wireless by a well-known method, and perform pairing processing by exchanging and registering pairing information (address and encryption key). (S101, S201). The CPU 1 of the receiving apparatus 100 has registered the identification information (pairing information) of the transmitting apparatus 200 that has newly performed the pairing process in the item having the highest priority in the connection history table, and has already been registered in the connection history table. The identification information of the other transmission devices 200 is decremented by one priority (S102). As a result of this processing, the receiving device 100 first searches for the transmitting device 200 newly paired with the receiving device 100 as shown below.

  FIG. 4 is a flowchart illustrating processing of the CPU 1 of the receiving device 100 when the receiving device 100 is not connected to the transmitting device 200. Although not particularly limited, in the receiving apparatus 100, portions other than the human sensor 7 and the CPU 1 are in a standby state. The human sensor 7 constantly monitors the presence of a human by a well-known method (S111). The CPU 1 determines whether or not human presence is sensed by the human sensor 7 (S112). For example, when a person who has the transmission device 200 enters a room in which the reception device 100 is arranged, the presence sensor 7 is detected by the human sensor 7 and the result is notified to the CPU 1. The CPU 1 determines that the presence of a human being is detected by the human sensor 7 (YES in S112). The CPU 1 shifts the receiving apparatus 100 from the standby state to the power-on state and shifts to the Bluetooth connectable state.

  The CPU 1 determines whether or not at least one piece of identification information of the transmission device 200 is registered in the connection history table (S113). If no identification information of the transmission device 200 is registered in the connection history table (S113), the process is terminated. On the other hand, when at least one piece of identification information of the transmission device 200 is registered in the connection history table (YES in S113), the CPU 1 indicates a value i = 1 indicating an item number (any one of 1 to 8) in the connection history table. (S114). i = 1 is the item with the highest priority as described above.

  The CPU 1 automatically searches for the transmission device 200 specified by i (S115). Specifically, the identification information (address, encryption key) of the transmission device 200 specified by i is read from the connection history table, and polling processing is executed. The CPU 1 determines whether or not a response to polling has been received from the transmission device 200 specified by i (S116). That is, as a result of the search, it is determined whether or not the transmission device 200 identified by i has been found. When the transmission device 200 identified by i exists within the wireless range, a response is returned from the transmission device 200. On the other hand, when the transmission device 200 identified by i does not exist within the wireless range, no response is returned from the transmission device 200.

  When a response cannot be received from the transmission device 200 specified by i (NO in S116), that is, when the transmission device 200 specified by i does not exist within the wireless range and cannot be found, the CPU 1 increments i ( S121). In the CPU 1, i is equal to or less than a predetermined number (the predetermined number is the number in which the identification information of the transmission device 200 can be registered in the connection history table, 8 in this example), and the item specified by i is the transmission device. It is determined whether 200 pieces of identification information are registered (S122). When i is larger than a predetermined number, or when the identification information of the transmission device 200 is not registered in the item specified by i (NO in S122), all the transmission devices 200 registered in the connection history table. This means that it was found in order, but the process ends. On the other hand, when i is equal to or less than the predetermined number and the identification information of the transmission device 200 is registered in the item specified by i (YES in S122), all the transmission devices 200 registered in the connection history table. Since the search has not been finished yet, the CPU 1 returns to S115 and searches for the transmission device 200 specified by i (S115). Therefore, the CPU 1 executes a search in order from the transmission device 200 having the highest priority in the connection history table.

  When a response is received from the transmission device 200 specified by i (YES in S116), the CPU 1 automatically establishes a wireless connection with the transmission device 200 specified by i (S117). A well-known technique can be adopted for the connection process itself.

  The CPU 1 transmits an instruction to start the playback application program to the connected transmission device 200 via wireless (S118). When the CPU 11 of the transmission device 200 receives an instruction to start the playback application program, the CPU 11 starts the playback application program if it has not been started. Subsequently, the CPU 1 transmits a reproduction instruction to the connected transmission device 200 (S119). When receiving the reproduction instruction, the CPU 11 of the transmission apparatus 200 starts reproduction of the music file and transmits the music data to the reception apparatus 100 via wireless if the music file is not being reproduced. When receiving the music data, the receiving device 100 reproduces the music data by the reproducing unit 5 and outputs sound from the speaker 6.

  If the priority order of the connection history table of the transmission device 200 specified by i is not the highest, the CPU 1 moves the priority order in the connection history table of the transmission device 200 specified by i to the highest item, and the other transmission device. The priority of 200 is lowered one by one (S120). For example, in the state of FIG. 2A, when a wireless connection is established with i = 3 transmitting apparatus C, the table is rewritten so that the priority order of transmitting apparatus C is the highest as shown in FIG. 2B.

  As a result of the above processing, when the user who owns the transmission device 200 approaches the reception device 100, the reception device 100 is automatically turned on, and the transmission device 200 is sequentially turned on according to the priority order registered in the connection history table. When the transmission device 200 is found by searching, the transmission device 200 and the reception device 100 are automatically connected. In response to an instruction from the receiving device 100, the transmitting device 200 playback application program is activated to start playback of the music file. Therefore, music can be automatically reproduced from the receiving device 100 only by the user holding the transmitting device 200 and approaching the receiving device 100. In addition, since the identification information of the transmitting device 200 connected last is registered in the item having the highest priority in the connection history table, when the music file of the same transmitting device 200 is transmitted to the receiving device 100 next time, it is received. The device 100 can immediately discover and automatically connect to the transmission device 200 (without having to search for a plurality of transmission devices 200).

  In this embodiment, since the connection history tables of FIGS. 2A to 2B need only be managed on the RAM, the management content in the RAM is very simple, which can contribute to the reduction of the used capacity of the RAM. .

  FIG. 5 is a flowchart showing the processing of the CPU 1 when the human sensor 7 no longer senses human presence. When the receiving device 100 is connected to the transmitting device 200 (receives and reproduces music data) (S131), the human sensor 7 constantly monitors the presence of a person. The CPU 1 determines whether the presence of a person is detected by the human sensor 7 (S132). When the presence of a human is sensed (YES in S132), the CPU 1 continues the connection with the transmission device 200 and the process of receiving and playing music data from the transmission device 200. On the other hand, for example, when a person carrying the transmission device 200 goes out of a room where the reception device 100 is arranged, the presence sensor 7 is not detected by the human sensor 7 and the result is notified to the CPU 1. CPU 1 determines that human presence is no longer detected by human sensor 7 (NO in S132). At this time, the CPU 1 automatically releases the wireless connection with the transmission apparatus 200 (no longer receives music data from the transmission apparatus 200), shifts to a standby state, and shifts to the processing of S101 in FIG.

  Even if a person carrying the transmission device 200 leaves the room where the reception device 100 is located, if the transmission device 200 is within the wireless range of the reception device 100, the reception from the transmission device 200 is received. Music data is transmitted to the device 100. Therefore, the receiving device 100 cannot disconnect the wireless connection with the transmitting device 200 depending on whether or not music data is received. Therefore, in the present embodiment, when the human sensor 7 no longer senses the presence of a person, the wireless connection with the transmission device 200 is automatically disconnected. Therefore, the wireless connection and the music data transmission / reception between the receiving apparatus 100 and the transmitting apparatus 200 are maintained despite the absence of a person, and the wasteful power consumption of the receiving apparatus 100 and the transmitting apparatus 200 is prevented from occurring. it can. Also, in Bluetooth, since one transmission device can be connected to only one reception device, the user who owns the transmission device 200 is in another room by being automatically disconnected by the human sensor 7. When approaching another receiving apparatus 100, it becomes possible to automatically connect to another receiving apparatus 100.

  Next, a modification of the process of FIG. 4 will be described. FIG. 6 is a flowchart showing the processing of this example. The same processing as in FIG. In FIG. 6, if it is determined in S122 that i is greater than the predetermined number, or the identification information of the transmission device 200 is not registered in the item specified by i (NO in S122), that is, If all the transmission devices 200 registered in the connection history table have been searched, the CPU 1 returns to S114, initializes to i = 1, and gives priority to the transmission device 200 registered in the connection history table again. Search in descending order. By performing the processing in this way, after the transmission device 200 is searched for in the connection history table but cannot be found, the transmission device 200 comes within the wireless range of the reception device 100, and the second and subsequent times. The transmission device 200 can be found in the search of Also, as shown in FIG. 7, an index j is defined, j is initialized to 1 in S131, and when NO is determined in S122, j is incremented in S132 and j is incremented to a predetermined number (eg, three times) in S133. ) It is determined whether the following is true. If j is equal to or smaller than the predetermined number (YES in S133), the process returns to S114. If j exceeds the predetermined number (NO in S133), the process is terminated. Therefore, according to FIG. 7, it is possible to prevent the search for the transmission device 200 from being continued until when.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. Depending on the specifications of the transmission apparatus 200, only the playback instruction may be transmitted without transmitting the playback application activation instruction. The receiving device 100 may play back content (for example, a video file or a still image file) other than a music file on the playback device. The communication standard is not limited to Bluetooth, and a wireless LAN, wireless HDMI, or any other wireless communication standard can be appropriately selected and adopted. The present invention may be provided in the form of a computer program for operating the receiving device 100 and the transmitting device 200 of the present invention or a recording medium recording the computer program.

  The present invention can be suitably applied to, for example, a stationary audio device and a portable music player.
