When the user presses the fast forward playback key of the remote controller 30, the remote controller 30 sends out a key code for instructing fast forward playback.

[0125] Remote control receiver 16 receives this key code and sends the key code to code selector 15.

The code selecting section 15 determines whether the key code is for controlling itself or for controlling another device.
The key code for controlling itself is sent to the command execution unit 17, and the key code for controlling other devices is sent to the digital I / F 10.
Send to Incidentally, when a key code for controlling itself is sent to the instruction execution unit 17, the instruction execution unit 17 executes the instruction content of this key code. For example, an instruction to change the receiving channel of the tuner 18 of the STB 2 is executed.

Since the key code for instructing fast-forward reproduction sent from the remote controller is a key code for controlling another device, the code selecting section 15 sends this key code to the digital I / F 10.

The digital I / F 10 is connected to the transfer destination storage means 1
1 by referring to the device name and node number stored in
The key code sent from the code selection unit 15 is transferred to the device having the node number stored in the transfer destination storage unit 11. That is, as described above, this key code is transferred to VTR1 (3). Thus, the controller 6 transfers the key code sent from the remote controller 30 to the controlled device.

VTR 1 (3) receives this key code as target 22. That is, digital I / F
23 receives the key code and outputs the key code
Send to 4.

The key code detector 24 determines the key code. If the key code is a GUI update command, the key code is sent to the GUI information output unit 26. If the key code is an operation command, the key code is sent to the command execution unit 25. Since the key code just sent is a key code for instructing fast-forward playback, the key code detection unit 24 sets the instruction execution unit 2
Send the key code to 5.

The command execution section 25 executes fast forward reproduction.

As described above, the remote controller 30 can control the VTR 1 (3) to perform fast forward reproduction.

That is, as a default, the device to be controlled by the remote controller 30 has a broadcast-out-connection on channel 63.
It is a device that is on.

The remote controller 30 has a VT
Since R1 (3) is the controlled object by default, not only fast-forward playback, but also VTR1 (3) can be freely controlled such as playback, still, rewind playback, recording, recording pause, stop, fast-forward, and rewind. You can do it.

The operation in which the device stored in the transfer destination storage means 11 is controlled by the remote controller 30 has been described above.

Next, it is assumed that the user tries to reproduce the AV data recorded on the VTR 3 (5). In this case, as described above, it is possible to reproduce the VTR 3 (5) even by pressing the reproduction key on the operation panel of the VTR 3 (5). Here, another method will be described.

[0137] That is, an operation of switching a device to be controlled by the remote controller 30 using the remote controller 30 will be described.

When the user attempts to reproduce the AV data recorded on the VTR 3 (5), the character "VTR1" is displayed on the upper right of the screen of the monitor 7 as shown in FIG. That is, the VTR 1 (3) is controlled by the remote controller 30.

Then, the user presses the device switching key of the remote controller 30.

Then, the remote controller 30
Sends a key code for instructing device switching.

The remote control receiving section 16 receives the key code sent from the remote controller 30 and sends it to the code selecting section 15.

The code selection section 15 determines a key code. That is, since the sent key code is a key code for changing the transfer destination, the key code is sent to the digital I / F 10.

The digital I / F 10 is connected to the transfer destination storage unit 1
Reference is made to the device name and node number stored in No. 1. Then, the node number stored in the bus configuration unit 12 and the node number having the next largest number after the node number stored in the transfer destination storage unit 11 and the device name of the node number are stored in the transfer destination storage unit 11. Remember. If there is no node number having a higher number than the node number stored in the transfer destination storage unit 11, the node number having the smallest number and the name of the device having that node number are stored in the transfer destination storage unit 11.
To memorize. Thus, the transfer destination storage means 1 is newly added.
The device name stored in “1” indicates “VTR2 (4)”
TR2 ".

Further, the digital I / F 10 includes a GUI including a device name newly stored in the transfer destination storage means 11.
The information is sent to the GUI information acquisition unit 13.

[0145] The GUI information acquisition unit 13 outputs the GUI information to the display unit 14.

The display section 14 outputs an OSD to the monitor 7.

As a result, “VTR1” is displayed at the upper right of the screen of the monitor 7 as shown in FIG. 5, and is switched to “VTR2”. In this way, the device to be controlled by the remote controller 30 is
It is possible to switch from (3) to VTR2 (4).

STB2, VTR1 (3), VTR2
(4), the names of VTR3 (5) are "STB",
It is assumed that “VTR1”, “VTR2”, and “VTR3”, and the node numbers increase in this order.

Then, similarly to the above description, when the user further presses the device switching key of the remote controller 30, the device to be controlled by the remote controller 30 is switched from the VTR 2 (4) to the VTR 3 (5). In the upper right corner of the screen of the monitor 7, "VTR3" is displayed.

When the user successively presses the device switching key of the remote controller 30, the devices to be controlled by the remote controller 30 are VTR1 (3), VT
R2 (4), VTR3 (5), STB2, VTR1
(3) Switching is performed in the order of device node numbers as in.

Therefore, if the user presses the device switching key of the remote controller 30 one after another and stops pressing the device switching key when the device to be controlled becomes the VTR 3 (5), the VTR 3 (5) Can be controlled by the remote controller 30.

Here, when the reproduction key of the remote controller 30 is pressed, the VTR 3
AV data recorded in (5) can be reproduced. However, when the VTR 3 (5) receives the key code for reproducing the AV data, the VTR 3 (5) sets the broadcast to the 63 channel.
It is assumed that a cast out connection is established.

As described above, the digital I / F 10 does not switch another device as a control target by the remote controller 30 for three minutes after changing the device to be controlled by the remote controller 30. As long as the name and the node number of the controlled device stored in the transfer destination storage unit 11 are not rewritten, That is, 3
During the minute, by operating the operation panel of another device, the device other than the device controlled by the remote controller 30 is set to 63 channels and Broadcast.
Even if the st out connection is set, the control target of the remote controller 30 is not changed.

Further, the user operates the remote controller 30.
When a menu key for giving an instruction to display the GUI screen is pressed, the remote controller 30 transmits a key code indicating an instruction to display the GUI.

[0155] Remote control receiver 16 receives this key code and sends it to code selector 15.

The code selector 15 sends this key code to the digital I / F 10.

The digital I / F 10 is connected to the transfer destination storage unit 1
This key code is sent to the device having the node number stored in 1. It is assumed that this device is a VTR 3 (5).

Then, VTR 3 (5) receives this key code as target 22 at digital I / F 23.

The digital I / F 23 sends the received key code to the key code detector 24.

The key code detector 24 detects that the key code is G
Since this is a UI update command, this key code is sent to the GUI information output unit 26.

The GUI information output section 26 outputs GUI information for controlling itself to the digital I / F 23.

The digital I / F 23 sends the GUI information to the controller 6.

The digital I / F 10 of the controller 6 is G
Receive UI information.

[0164] The GUI information acquisition unit 13 is a digital I / F
10 acquires the received GUI information and sends it to the display unit 14.

The display unit 14 displays the GUI information on the monitor 7
Output to SD.

The user operates the GU displayed on the monitor 7.
The user operates the remote controller 30 while watching the I information.

In some cases, the user needs to update the GUI information by operating the remote controller 30 while viewing the GUI information displayed on the monitor 7. For example, suppose that the selection items on the GUI screen displayed on the monitor 7 are “recording” and “reproduction” in a scene of selecting whether to record or reproduce. When "playback" is selected to perform playback, it is assumed that there is a GUI screen for determining whether to perform playback at a normal speed or fast forward.

In such a case, the remote controller 3
0 sends a key code corresponding to "play", and the controller 6 sends this key code to, for example, the VTR 1 (3). The VTR 1 (3) uses the key code detection unit 24 as the target 22 to determine whether the key code is a GUI update command or an operation command. For this determination, the key code detection unit 24 makes a determination also using the GUI information currently displayed on the monitor 7. Then, the key code is sent to the GUI information output unit 26, and the GUI information output unit 26 outputs GUI information for determining whether to perform normal reproduction or fast-forward reproduction.

The GUI information is transmitted to the controller 6
The case of controlling the controlled device by displaying it on the monitor 7 will be described in detail in a fourth embodiment.

As described above, since the devices to be controlled can be freely switched by the remote controller 30, a plurality of devices connected to the bus 1 can be easily controlled by using only one remote controller. You can do it.

In this embodiment, the controller 6
(STB2) is 63 channel and Broadcast
