In particular, the present invention relates to a video / audio reproduction system in which a video / audio signal reproduction device includes a plurality of input / output signal terminal sets and a slave device of a wireless signal transmission / reception device can be arranged in a plurality of zones.

  A content playback device including an audio playback device such as a CD player or a video recording / playback device such as an HDD video recorder or a DVD player is connected to an AV amplifier device including a plurality of input / output signal terminal sets. Thus, the video / audio reproduction system is used. The AV amplifier device includes an input selector that switches input signals from a plurality of content playback devices.

Similarly, the AV amplifier device includes an output selector that switches a video / audio signal to be output to another connected audiovisual apparatus.

  For example, a video / audio device connected to an AV amplifier device is a module externally attached to the AV amplifier device via a connector, and may be an optional unit that enhances the function of the AV amplifier device (Patent Literature). 1).

  Furthermore, the AV amplifier device may have a function of outputting video to a plurality of zones, outputting audio speakers, or outputting pre-out. In other words, the AV amplifier device is connected not only to other video / audio devices installed in the main zone where the AV amplifier device itself is installed, but also to other video / audio devices installed in a plurality of other zones. , May play back video and audio. Therefore, in order to operate an AV amplifier device located in the main zone from another zone, there is a case where a control signal is communicated via another video / audio device installed in that zone.

  For example, conventionally, in a multi-zone AV system, there is a function control device for a multi-zone AV system that can simultaneously operate each function such as a volume function and an input switching function (Patent Document). 2).

  On the other hand, the AV amplifier device is connected by a control line for transmitting / receiving a control signal so as to enable a system-linked operation with the content reproduction device and other video / audio devices installed in other zones. The control line is not limited to HDMI (registered trademark) (High-Definition Multimedia Interface) integrated with a signal line for transmitting video / audio signals, but is connected with an independent signal line or wirelessly. When connected to each other by communication, etc. are included. The AV amplifier apparatus receives an operation input by a remote control signal in addition to an operation input by an input interface including an input button on the operation panel, and sends a control signal to the content reproduction apparatus and other video / audio equipment installed in another zone. It is possible to send.

  In particular, when another video / audio device connected to the AV amplifier device is a wireless signal transmission / reception device including a parent device and a plurality of child devices connected wirelessly to the parent device, the wireless signal transmission / reception device and the child device There is a problem that it is necessary for the AV amplifier device to distinguish between which zone the control signal corresponding to the device is assigned. In addition to the fact that the AV amplifier device may not know a communication control signal between the parent device and the child device even when an operation input is made to the child device of the wireless signal transmitting / receiving device, the AV amplifier device This is because it may be preferable that the control signal between the radio signal transmitting / receiving apparatus and the radio signal transmitting / receiving apparatus is differentiated into separate control signals to correspond to each zone. In addition, since the parent device of the wireless signal transmitting / receiving device and the plurality of child devices are wirelessly connected, appropriate control operations differ depending on which zone the child device is located.

Further, the slave unit 24 of the wireless option device 20 is arranged in a zone 3 (Zone 3) which is a place different from the main zone arrangement zone 2.

  Therefore, the video / audio reproduction system 1 not only reproduces audio through the slave unit 22 of the wireless option device 20 in the main zone where the AV amplifier 10 is installed, but also wirelessly installed in another zone 2 or zone 3. Audio reproduction is possible via the slave unit 23 or 24 of the optional device 20. In the main zone and zone 2 or zone 3, the same audio source may be reproduced, or different audio sources may be reproduced. Furthermore, the AV amplifier 10 located in the main zone can be operated not only from the slave unit 22 in the main zone but also from the slave unit 23 in the other zone 2 or the slave unit 24 in the zone 3.

  FIG. 2 is a block diagram and table for explaining the video / audio reproduction system 1 according to the preferred embodiment of the present invention. Specifically, the block diagram of FIG. 2A is a diagram for explaining an input / output signal terminal set of the AV amplifier 10, a reproduction zone corresponding to these, and a wireless transmission channel of the wireless signal transmitting / receiving apparatus, It is described corresponding to a part of the configuration (main zone and zone 2) in the block diagram of FIG. In addition, about the subunit | mobile_unit 24 arrange | positioned in the zone 3, illustration and description are abbreviate | omitted.

  2 (b) to 2 (d) show information to be referred to by the CPU constituting each control unit of the AV amplifier 10, the master unit 21 of the wireless option device 20, and the slave units 22, 23, or 24. It is a table. Specifically, FIG. 2B is a table of connection information that stores a zone in which the AV amplifier 10 reproduces sound and a wireless transmission channel of the wireless option device 20. FIG. 2C is a table of parent device connection information that stores the wireless transmission channel and the individual identification numbers of the child devices 22, 23, or 24. FIG. 2D is a table of a remote control code conversion table of the wireless option device 20 corresponding to each zone in which the AV amplifier 10 reproduces sound.

  As shown in FIG. 2A, for example, in the video / audio reproduction system 1, the terminal 11 of the AV amplifier 10 and the terminal 25 of the base unit 20 of the wireless option device 20 are connected to each other. An audio signal transmitted from the signal transmission unit of the handset 22 to the wireless transmission channel CH1 is input to the input PORT IN which is an input terminal. Therefore, the audio signal from the handset 22 can be input to the audio signal input / output unit of the AV amplifier 10.

  Also, the audio signal input / output unit of the AV amplifier 10 transmits the audio signal output from the set of audio signal output terminals such as REC OUT or ZONE2 OUT from the signal transmission unit of the base unit 20 of the wireless option device 20 to the wireless transmission channel. It can be transmitted to the slave unit of the wireless option device 20 on CH2. Similarly, the audio signal input / output unit of the AV amplifier 10 receives the audio signal from the set of output terminals such as SURROUND BACK (SURRBK) OUT or ZONE3 OUT, which is a terminal for outputting the rear signal of the multi-channel surround signal, as a wireless optional device. It can be transmitted from the signal transmission unit of the 20 base units 20 to the slave unit of the wireless option device 20 on the radio transmission channel CH3.

  At this time, an operation event from the remote controller 32 input to the slave unit 22 arranged in the main zone of the wireless option device 20 is transmitted to the master unit 21 as a remote control signal, and the control unit of the amplifier 10 is transmitted via the master unit 21. Is transmitted. Similarly, an operation event from the remote controller 33 input to the slave unit 23 arranged in the zone 2 is transmitted to the master unit 21 as a remote control signal and transmitted to the control unit of the AV amplifier 10 via the master unit 21. . Since the control unit of the AV amplifier 10 does not know the remote control code signal between the master unit and the slave unit of the wireless option device 20, in order to achieve different appropriate control in the main zone and zone 2, the control of the master unit 21 is performed. The unit needs to convert the control signal (remote control signal) to the control unit of the AV amplifier 10 and the control unit of the slave unit 22 and the slave unit 23 by the control signal conversion unit, and communicate or transmit. This is because the control signals between the AV amplifier 10 and the wireless option device 20 are classified into separate control signals to correspond to the respective zones.

  Therefore, the control unit of the AV amplifier 10 stores the reproduction zone corresponding to each input / output signal terminal set and the wireless transmission channel of the wireless option device 20 as shown in FIGS. 2 (a) and 2 (b). Stores clue information. This association information is transmitted to the base unit 21 of the wireless option device 20 as described later. This association information is set so as to differ depending on the type, form, etc. of the AV amplifier 10. In the case shown in FIG. 2, the wireless transmission channel CH3 corresponds to the ZONE3 output, but if it is an AV amplifier 10 that outputs an audio signal from the SURRBK output without providing the ZONE3 output, The hooking information may be stored so that the SURRBK output, which is the voice output to the main zone, is associated with the radio transmission channel CH3.

  Further, as shown in FIG. 2C, the control unit of the base unit 21 of the wireless option device 20 sets the wireless transmission channel corresponding to the input / output signal terminal set and the individual identification number of the handset 22, 23, or 24. The base unit connection information to be stored is stored. Further, the control signal conversion unit of the parent device 21 stores an operation event-remote control code conversion table as shown in FIG. The control signal conversion unit converts the control signal from the slave unit included in the wireless transmission channel with reference to the connection information and the base unit connection information, and outputs the control signal to the control signal communication unit. In the parent device 21 of the wireless option device 20, the signal transmission unit communicates with the child device based on the parent device connection information storing the wireless transmission channel corresponding to the input / output signal terminal set and the individual identification number of the child device. And transmit wirelessly. The control signal communication unit communicates with the AV amplifier 10 a control signal including connection information.

  3 and 4 are flowcharts for explaining the control operation of the video / audio reproduction system 1. Specifically, FIG. 3 illustrates an initial state setting operation associated with the connection between the AV amplifier 10 and the wireless option device 20. FIG. 4 illustrates operation control of each control unit of the AV amplifier 10, the parent device 21 of the wireless option device 20, and the child device 22 in accordance with a remote control operation on the child device 22 of the wireless option device 20.

  When the base unit 21 of the wireless option device 20 is connected to the AV amplifier 10 (S101, S111), the control unit of the AV amplifier 10 stores the hooking information stored via the control signal communication unit to the base unit 21. Transmit (S102). The control unit of the base unit 21 of the wireless option device 20 receives and stores the association information transmitted via the control signal communication unit (S112), and ends the association information setting operation (S103, S113). . That is, when the master unit 21 of the wireless option device 20 is connected, the AV amplifier 10 determines the relationship between the setting of the zone corresponding to the set of its input / output terminals and the channel of the master unit 21 and communicates control signals. To the base unit 21 of the wireless option device 20.

  Next, the master unit 21 and the slave unit 22 of the wireless option device 20 start wireless connection with each other (S114, S121). The control part of the subunit | mobile_unit 22 transmits the channel number of the main | base station 21 connected via a signal transmission part to the main | base station 21 (S122). The control unit of the parent device 21 receives the channel number of the child device 22 that the child device 22 wants to connect from the control signal received through the signal transmission unit (S115), updates the parent device connection information (S116), and The update operation of the machine connection information is finished (S117, S123). Accordingly, in the video / audio reproduction system 1, the AV amplifier 10 can be remotely controlled by the remote controller 32 from the slave unit 22 of the wireless option device 20.

  The operations of the control units of the AV amplifier 10 and the base unit 21 and the handset 22 of the wireless option device 20 will be described with reference to the flowchart of FIG. When the remote control operation is started from the slave unit 22 of the wireless option device 20 (S201, S211, S221), for example, when the user presses the VolumeUP button of the remote control 32 (S222), the operation input unit of the slave unit 22 is The infrared signal transmitted from the remote controller 32 is received as a VolumeUP event code (S223). The control unit of the slave unit 22 wirelessly transmits the VolumeUP event code to the master unit 21 of the wireless option device 20 via the signal transmission unit (S224).

  When the control unit of the master unit 21 receives the VolumeUP event code via the signal transmission unit (S212), the channel to which the slave unit 22 is connected with reference to pre-established connection information and master unit connection information It is confirmed which number corresponds to the main zone / zone 2 / zone 3 (S213). Then, since the control signal conversion unit refers to the stored operation event-remote control code conversion table and obtains the remote control code of the Volume UP event of the corresponding zone (S214), the control unit of the parent device 21 controls the control signal. The remote control code is transmitted to the AV amplifier 10 via the communication unit (S215).

  When the control unit of the AV amplifier 10 receives the remote control code from the parent device 21 via the control signal communication unit (S202), the control unit increases the volume for controlling the volume of the corresponding zone (S203), and the remote control 32 The remote control by is terminated (S204, S216, S225). In the case of the above embodiment, since the remote control 32 of the handset 22 of the wireless option device 20 arranged in the main zone is operated, the volume of sound reproduced in the main zone can be increased. If the handset 22 includes an operation input unit including buttons, switches, and the like, user operations on the handset 22 can be similarly reflected in the operation of the AV amplifier 10.

  Further, when the remote control 33 or 34 of the slave unit 23 or 24 of the wireless option device 20 arranged in the zone 2 or the zone 3 is individually operated, the volume of the sound reproduced in the respective zone 2 or the zone 3 is set. Needless to say, it can be raised individually. This is because the control signal conversion unit of the parent device 21 can calculate different control signals according to a plurality of operation inputs or remote operation inputs for different reproduction zones. That is, in this video / audio reproduction system 1, video / audio reproduction is performed on each of the slave units 22 to 24 by an operation input or a remote control input to the slave units 22 to 24 of the wireless option device 20 located in each of the playback zones. It is possible to make the control possible and prevent the operation input or the remote operation input from being reflected on the slave device in another reproduction zone.

  It is preferable that the wireless option device 20 constituting the video / audio reproduction system 1 connected to the AV amplifier 10 corresponds to the type, model and format of the AV amplifier 10 which are different for one model. If the hooking information can be set differently according to the type, type, etc. of the AV amplifier 10 as in the present embodiment, it can be used as a common option unit compatible with a plurality of AV amplifiers 10. There is an advantage that it can be designed.

  In the case of the present embodiment, the control signal conversion unit of the base unit 21 refers to the stored operation event-remote control code conversion table. However, even if such a conversion table is not provided, it is appropriate. Any other method may be employed as long as it is a method for calculating the control signal. In addition, any control unit that controls the video / audio reproduction system 1 can be employed as long as it substantially stores the transmission information and the base unit connection information, and transmits and calculates the control signal. It may be based on other methods.

  The optional unit 20 of the AV amplifier 10 is a module that is externally attached to the AV amplifier 10 by wired connection, but may be a module that can be wirelessly connected to the AV amplifier 10. Of course, the AV amplifier 10 may be configured integrally with the base unit 21 of the option unit 20 built-in.

  The video / audio reproduction system, the video / audio signal reproduction device, and the radio signal transmission / reception device of the present invention are not only a stereo device or a multi-channel surround sound reproduction device that reproduces content including a digital audio signal, but also a video / audio such as a display. It can also be applied to equipment.
