Description

  The present invention relates to a remote control signal relay device and an AV system, and more particularly, to a remote control signal relay device and an AV system that are connected to a speaker device and an AV device and relay a signal from the remote control device and transmit the signal to the speaker device or AV device. About.

The remote control device is provided as a standard in various electronic devices such as speaker devices and AV devices. By operating each remote control device toward the corresponding electronic device, each electronic device can be operated from a distant place. .
On the other hand, it is inconvenient for the user to operate each remote control device toward the corresponding electronic device. For example, Patent Document 1 discloses a technique of a remote control signal relay device, and the corresponding electronic device can be operated by operating each remote control device toward the remote control signal relay device.

  However, it is inconvenient for the user to operate the speaker device by holding the remote control device for the speaker device and to operate the AV device by switching to the AV device remote control device. It is. For example, Patent Document 2 discloses a technique of a remote control signal relay device that can be operated by one remote control device.

JP 2003-283406 A Japanese Patent No. 3218141

  However, in the technique of Patent Document 2, the AV device may receive the operation signal (command) from the remote control device via the remote control signal relay device and directly from the remote control device. If the AV device receives the same signal at the same time, the command cannot be received due to crosstalk, and if the AV device receives it twice, the operation will be contrary to the user's intention.

  Here, as one method for enabling operation with one remote control device, there is a mechanism called CEC (Consumer Electronics Control) in the HDMI (High Definition Multimedia Interface) standard. By directly exchanging control signals between the speaker device and the AV device, for example, the AV device ignores the volume control signal sent from the remote control device for the AV device to the AV device, and HDMI (registered trademark) It is possible to control the volume of the speaker device by sending the signal to the speaker device via.

  However, in this case, a configuration capable of inputting and outputting HDMI (registered trademark) is required for the speaker device in addition to the AV device. That is, there is a problem that the speaker device cannot be manufactured at low cost because the speaker device is configured to handle not only sound but also video (for example, a pass-through function of input video).

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a remote control signal relay device and an AV system that can be operated with one remote control device and that can manufacture a speaker device at low cost. And

  In order to solve the above problems, a first technical means of the present invention is a remote control signal relay device connected to a speaker device and an AV device, relaying a signal from a remote control device and transmitting the signal to the speaker device or the AV device. The remote control signal relay device is provided at a position that shields the device receiving unit of the AV device, and receives a signal from the remote control device, and analyzes the signal received by the receiving unit. An analysis unit, a transmission control unit for determining whether to transmit the signal received by the reception unit to the device reception unit of the AV device, based on the analysis result of the signal by the analysis unit, and the reception unit A transmission unit configured to transmit the received signal to the speaker device or the device reception unit of the AV device, and the transmission control unit includes a signal analysis result of the analysis unit related to voice control. A signal related to the audio control from the transmission unit to the AV device is prohibited, and the signal related to the audio control is transmitted from the transmission unit to the speaker device. is there.

  According to a second technical means, in the first technical means, the transmission control unit transmits the power on / off signal when the analysis result of the signal by the analysis unit is a power on / off signal. Is transmitted to the AV device and the speaker device from the unit.

  The third technical means is an AV system in which the first or second technical means relays a signal from the remote control device and transmits the signal to the speaker device or the AV device.

  According to the present invention, since the remote control signal relay device is provided at a position that shields the device receiving unit of the AV device, the AV device does not receive the same signal. In addition, since the signal related to audio control is not transmitted to the AV device but transmitted to the speaker device, for example, when controlling the volume of the speaker device, for example, an HDMI (registered trademark) input / output unit is not mounted on the speaker device. I'll do it. Therefore, the AV device and the speaker can be operated with one remote control device, and the speaker device can be manufactured at low cost.

Example 1
DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments according to a remote control signal relay device and an AV system of the invention will be described with reference to the accompanying drawings.
FIG. 1 is a diagram showing a schematic configuration of an AV system according to an embodiment of the present invention. The AV system includes, for example, a television receiver 1, a speaker device 5, and a remote control signal relay device 10. The television receiver 1 corresponds to the AV device of the present invention, and the speaker device 5 corresponds to the speaker device of the present invention. In FIG. 1, the AV system is viewed from the side, and the remote control device R is arranged on the front side of the television receiver 1. The remote control device R is, for example, a remote control device for a television receiver.

  The television receiver 1 is configured to display an image by performing image processing on an input video signal. In addition, the television receiver 1 includes a light receiving unit 2 that receives a signal (for example, an infrared signal: IR) from the remote control device R. The light receiving unit 2 corresponds to the device receiving unit of the AV device of the present invention. The light receiving unit 2 is provided, for example, in the lower frame of the television receiver 1 and can receive a signal from the front side. The television receiver 1 can be remotely operated by the remote control device R from the front side through a remote control signal relay device 10 described later.

  The remote control signal relay device 10 can relay the signal from the remote control device R and transmit it to the television receiver 1 and the speaker device 5. The remote control signal relay device 10 is disposed in front of the television receiver 1 and is provided, for example, at a position where the light receiving unit 2 is shielded. Therefore, the television receiver 1 cannot receive the operation signal from the remote control device R directly from the remote control device R but receives it via the remote control signal relay device 10.

  The speaker device 5 is formed to be elongated in the horizontal direction as a sound bar, for example, and is disposed in front of the television receiver 1. The speaker device 5 is connected to the television receiver 1 via the cable 3 and can reproduce powerful surround sound. In addition, the light receiving part is not provided. The speaker device 5 is connected to the remote control signal relay device 10 via the cable 4, and can be remotely operated by the remote control device R from the front side via the remote control signal relay device 10.

FIG. 2 is a diagram illustrating the configuration of the remote control signal relay device according to the first embodiment.
The remote control signal relay device 10 includes a reception unit 11 and a transmission unit 15. The receiving unit 11 is provided at a position where a signal from the front side can be received, and receives a signal from the remote control device R. The transmission unit 15 is provided at a position facing the light receiving unit 2 of the television receiver 1 described in FIG. 1 and transmits a signal from the remote control device R received by the reception unit 11 to the television reception device 1 or the speaker device 5. .

  The remote control signal relay device 10 includes a CPU, a memory (ROM, RAM), and the like, and includes a storage unit 12, an analysis unit 13, and a transmission control unit 14. The storage unit 12 can store a signal from the remote control device R received by the reception unit 11. The analysis unit 13 can analyze the signal from the remote control device R received by the reception unit 11. The transmission control unit 14 determines whether to transmit the signal from the remote control device R received by the receiving unit 11 to the light receiving unit of the television receiving device 1 based on the analysis result of the signal by the analyzing unit 13.

  The remote control signal relay device 10 is always in an energized state, and circuits necessary for power control of the television receiver 1 and circuits necessary for power control of the speaker device 5 are always energized.

FIG. 3 is a flowchart for explaining signal control according to the first embodiment.
In the remote control signal relay device 10 described with reference to FIG. 2, the receiving unit 11 receives a signal from the remote control device R (step S1). The reception result is output to the storage unit 12 and the analysis unit 13, and the storage unit 12 temporarily stores a signal from the remote control device R (step S2), and the analysis unit 13 analyzes the signal from the remote control device R (step S3). ). The analysis result is output to the transmission control unit 14.

The transmission control unit 14 determines whether or not the analysis result of the signal by the analysis unit 13 is a signal related to voice control (step S4). Examples of the signal related to voice control include control signals such as volume and surround on / off signals.
When the analysis result of the signal by the analysis unit 13 is a signal related to voice control (YES in step S4), the transmission control unit 14 transmits the signal related to voice control from the transmission unit 15 to the television receiver 1. Prohibit and transmit a signal related to the voice control from the transmitting unit 15 to the speaker device 5. Thereby, the transmission part 15 calls the signal regarding the said audio | voice control from the memory | storage part 12, and transmits only to the speaker apparatus 5 via the cable 4 demonstrated in FIG. 1 (step S5).

  As described above, since the signal relating to the audio control is not transmitted to the television receiver 1 but transmitted to the speaker device 5, it can be operated by one remote control device R. Furthermore, for example, when the volume of the speaker device 5 is controlled, the speaker device 5 does not have to be equipped with, for example, an input / output unit of HDMI (registered trademark), so that the speaker device 5 can be manufactured at low cost.

On the other hand, if the analysis result of the signal by the analysis unit 13 is not a signal related to voice control (NO in step S4), the process proceeds to step S6, and the transmission control unit 14 determines that the analysis result of the signal by the analysis unit 13 is power on / off It is determined whether it is a signal (step S6).
When the analysis result of the signal by the analysis unit 13 is a power on / off signal (YES in step S6), the transmission control unit 14 sends the power on / off signal from the transmission unit 15 to the television receiver 1. And transmitted to the speaker device 5. Thereby, the transmission unit 15 calls the power on / off signal from the storage unit 12 and transmits the signal to the light receiving unit 2 of the television receiver 1 described with reference to FIG. 5 (step S7).

  Thus, since the power on / off signal is transmitted to the television receiver 1 and the speaker device 5, the television receiver 1 and the speaker device 5 can be operated by one remote control device R.

  On the other hand, if the analysis result of the signal by the analysis unit 13 is not a signal related to voice control (NO in step S4) and is not a power on / off signal (NO in step S6), the process proceeds to step S8 and is transmitted. The control unit 14 causes the transmission unit 15 to transmit another control signal (for example, a channel signal) related to the television receiver 1, which is different from the signal related to audio control and the power on / off signal, from the transmission unit 15. Thereby, the transmission part 15 calls the said other control signal from the memory | storage part 12, and transmits toward the light-receiving part 2 of the television receiver 1 demonstrated in FIG. 1 (step S8).

  In this way, it is possible to provide an AV system that can be easily operated with a single remote control device R and can be manufactured at low cost.

(Example 2)
By the way, in the first embodiment, in order to operate the television receiver 1 and the speaker device 5 with one remote control device R, the remote control signal relay device 10 is provided at a position where the light receiving unit 2 of the television reception device 1 is shielded. .
However, when the remote control signal relay device is provided at a position that does not shield the light receiving unit of the television receiver, it is necessary that the television receiver does not directly receive the operation signal from the remote controller R. Therefore, the television receiver and the speaker device can be operated with one remote controller by the following configuration.

FIG. 4 is a diagram illustrating the configuration of the remote control signal relay device according to the second embodiment.
In the present embodiment, the transmission control unit 14 of the remote control signal relay device 10 can determine whether or not the signal is for specifying the television receiver 1 based on the signal received from the remote control device R. When the transmission control unit 14 determines that the signal is for specifying the television receiver 1, the transmission control unit 14 prevents the television receiver 1 from receiving a signal from the remote control device R so as to prevent the television receiver 1 from receiving a signal. 14a is transmitted. The transmission unit 15 transmits the interference signal 14 a toward the light receiving unit of the television receiver 1.

  The interference signal 14a is stored in the transmission control unit 14, for example. The interference signal 14a is a signal that is weak enough to reach only the light receiving unit of the television receiver 1 from the transmission unit 15 of the remote control signal relay device 10, and enters the receiving unit 11 of the remote control signal relay device 10 due to reflection or the like. Absent.

  Also in the second embodiment, the transmission control unit 14 determines whether to transmit the signal from the remote control device R received by the receiving unit 11 to the light receiving unit of the television receiving device 1 based on the analysis result of the signal by the analyzing unit 13. Can be determined. Further, the transmission unit 15 can transmit the signal from the remote control device R received by the reception unit 11 to the television reception device 1 or the speaker device 5. The configurations of the receiving unit 11, the storage unit 12, and the analyzing unit 13 have the same functions as those in the first embodiment, and thus detailed description thereof is omitted.

FIG. 5 is a flowchart for explaining the signal control of the second embodiment, and FIG. 6 is a flowchart for explaining the interference signal control of FIG.
In the remote control signal relay device 10 described with reference to FIG. 4, the receiving unit 11 receives a signal from the remote control device R (step S10 in FIG. 5). The reception result is output to, for example, the transmission control unit 14 in addition to the storage unit 12 and the analysis unit 13.

The transmission control unit 14 determines from a part of the data being received from the remote control device R whether the signal is for specifying the television receiver 1 (step S11 in FIG. 5 and step S20 in FIG. 6).
Specifically, for example, the remote control code in the home appliance association format is omitted, but the reader signal without data, the 48-bit data signal, the trailer signal indicating the end of the signal, and the frame space that does not output infrared light. These are arranged in order to form one frame.

  The leader signal is composed of an 8T on-period and a 4T off-period, and is formed of a signal having a length of 12T. The data signal includes a custom code for identifying the television receiver 1, a data code for controlling the television receiver 1, and the like. In the case of logic 1, a 1T on-period and a 3T off-period In the case of logic 0, it consists of an ON period of 1T and an OFF period of 1T.

  The transmission control unit 14 receives the reader signal and the data signal in this order. For example, when it is determined that the control signal is a part of the data signal to the television receiver 1 (YES in step S20 in FIG. 6), this television reception is performed. The apparatus 1 is caused to transmit an interference signal. Thereby, the transmission part 15 receives an interference signal from the transmission control part 14, and transmits toward the light-receiving part of the said television receiver 1 (step S21).

  As described above, while the interference signal is transmitted to the television receiver 1, the television receiver 1 cannot directly receive the operation signal from the remote control device R. Therefore, it is not necessary to provide the remote control signal relay device at a position that does not shield the light receiving unit of the television receiver, and the installation position of the remote control signal relay device is not restricted.

  Subsequently, the transmission control unit 14 continues to receive a signal from the remote control device R until it is determined that the data reception is completed. And the transmission control part 14 stops transmission of the interference signal to this television receiver 1, for example, when it determines with the data reception having been completed from the trailer signal (YES of step S22 of FIG. 6). Thereby, the transmission part 15 stops transmission of the interference signal to the light-receiving part of the television receiver 1 (step S23).

On the other hand, the storage unit 12 temporarily stores a signal from the remote control device R (step S12 in FIG. 5), and the analysis unit 13 analyzes the signal from the remote control device R (step S13). The transmission control unit 14 determines whether or not the analysis result of the signal by the analysis unit 13 is a signal related to voice control (step S14).
If the analysis result of the signal by the analysis unit 13 is a signal related to voice control (YES in step S14), the transmission control unit 14 stops the transmission of the interference signal to the television receiver 1, and then transmits the transmission unit. The transmission of the signal related to the audio control from 15 to the television receiver 1 is prohibited, and the signal related to the audio control is transmitted from the transmission unit 15 to the speaker device 5. Thereby, the transmission part 15 calls the signal regarding the said audio | voice control from the memory | storage part 12, and transmits only to the speaker apparatus 5 (step S15).

As described above, since the signal relating to the audio control is not transmitted to the television receiver 1 but transmitted to the speaker device 5, it can be operated by one remote control device R. Furthermore, for example, when the volume of the speaker device 5 is controlled, the speaker device 5 does not have to be equipped with, for example, an input / output unit of HDMI (registered trademark), so that the speaker device 5 can be manufactured at low cost.
On the other hand, if the analysis result of the signal by the analysis unit 13 is not a signal related to voice control (NO in step S14), the transmission control unit 14 determines whether the analysis result of the signal by the analysis unit 13 is a power on / off signal. Is determined (step S16).

  If the analysis result of the signal by the analysis unit 13 is a power on / off signal (YES in step S16), the transmission control unit 14 stops transmission of the interference signal to the television receiver 1, The power on / off signal is transmitted from the transmitter 15 to the television receiver 1 and the speaker device 5. Thereby, the transmission unit 15 calls the power on / off signal from the storage unit 12, transmits the signal to the light receiving unit of the television receiver 1, and transmits the signal to the speaker device 5 (step S17).

  Thus, since the power on / off signal is transmitted to the television receiver 1 and the speaker device 5, the television receiver 1 and the speaker device 5 can be operated by one remote control device R.

  On the other hand, if the analysis result of the signal by the analysis unit 13 is not a signal related to voice control (NO in step S14) and is not a power on / off signal (NO in step S16), the transmission control unit 14 Another control signal related to the television receiver 1 is transmitted from the transmission unit 15 to the television receiver 1. Thereby, the transmission part 15 calls the said other control signal from the memory | storage part 12, and transmits toward the light-receiving part of the television receiver 1 (step S18).
