DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an AV for a multi-room.
(Audio / video) system.

[0002]

2. Description of the Related Art A conventional multi-room AV system includes:
For example, as shown in FIG. 3, an AV amplifier (or receiver) 1 having a plurality of systems, for example, two systems of AV selectors, and a monitor TV (television) connected to the AV amplifier 1 are provided in a main room (for example, room A). 2), speakers 3 and 4 are arranged, and a monitor TV5 connected to a second room output terminal of the AV amplifier 1 and speakers 6 and 7 are arranged in a sub room (for example, room B). Was. Further, the AV amplifier 1 includes a remote control signal receiving (light receiving) device 10 for radio waves or infrared rays for the room A and a remote control signal receiving (light receiving) device 11 for the room B.
Are transmitted, and a remote control signal for the room A or B is transmitted (emitted) from the remote control commander 12 to the reception (light reception) device 10 or 11, thereby performing various operations of the AV amplifier 1 (for example, volume adjustment or input source selector selection). Switching, etc.). Also, the AV amplifier 1 has one built-in on-screen display (OSD) IC (not shown), and displays information on various operations of the AV amplifier 1 on the screen of the monitor TV 2 under the control of the OSDIC. The user in the room A can change the state of AV viewing while watching this display on the monitor TV.

[0003]

However, in the above-mentioned conventional configuration, various operation information is displayed only on the monitor TV2 in the room A, and the user in the room B cannot use the AV information.
The operation information of the amplifier 1 could not be known, which was inconvenient.

Further, a manual switching circuit 41 as shown in FIG. 4 is added to the AV amplifier 1, the switches S1 and S2, and the switches S3 and S4 are linked, and the switches S3 and S4 are turned on when the switches S1 and S2 are turned on. When turned off, the OSD input information of the room A from the input terminal 42 is output to the output terminal 44 via the OSDIC 11 and supplied to the monitor TV2. When the switches S3 and S4 are turned on, the switches S1 and S2 are turned off. Input terminal 43
Is input to the output terminal 45 via the OSDIC 11 and supplied to the monitor TV5, so that it can be displayed on the sub-room side. In this configuration, the user operates the switch every time. There was a problem that the operation had to be switched and the operation was troublesome.

An object of the present invention is to solve the above-mentioned conventional problems and provide an easy-to-use multi-room AV system.

[0006]

SUMMARY OF THE INVENTION A multi-room AV system according to the present invention is a multi-room AV system having a plurality of AV selectors for at least two rooms switchable by a remote controller. Means for determining a remote control code for each room, and switches the operation of the on-screen display IC for each room according to the result of the determination by the determination means.

[0007]

According to the present invention, the operation of the OSDIC is automatically switched to a dedicated operation for each room and displayed on the monitor TV of each room according to the result of the judgment.

[0008]

FIG. 1 is a block diagram showing an embodiment of a multi-room AV system according to the present invention. FIG.
The same reference numerals are given to the same components as in the conventional example. In FIG. 1, 1 is an AV stereo amplifier (or receiver),
2 is a monitor TV for the main room (room A), 3 and 4 are speakers for room A, and 5 is a sub room (room B)
Monitor TV, 6 and 7 are speakers for room B, 8 is OSDIC, 9 is a microcomputer (hereinafter referred to as microcomputer) for controlling the entire operation of the AV amplifier 1, 10 is a remote control signal receiving (light receiving) device for room A, 11 Is a remote control signal receiving (light receiving) device for room B, and 12 is a remote control commander. The remote control commander 12 is provided with a room selector key for selecting a room A or B, and a plurality of operation keys for performing various operations of the AV amplifier 1. A code dedicated to the room selected by the room selector key is provided. Can be transmitted.

In the above configuration, when a user in the room A transmits a remote control signal having a code for the room A using the remote control commander 12 to adjust the AV viewing environment, the remote control signal for the AV room A is received. (Received light) The AV amplifier 1 received by the device 10 and the microcomputer 9 determines that the signal is a remote control signal for the room A by the microcomputer 9,
Under the control of the microcomputer 9, various adjustments and switching operations for the room A are performed, and the operation of the OSDIC 8 is controlled to the room A.
And switch the room A OSD information to monitor TV2
Display on the screen. Similarly, when a user in room B transmits a remote control signal having a code for room B using remote control commander 12 in order to adjust the AV viewing environment, remote control signal receiving (light receiving) device 11 for AV room B The AV amplifier 1 determines that the signal is a remote control signal for the room B by the microcomputer 9,
Under the control of the microcomputer 9, various adjustments and switching operations for the room B are performed, and the operation of the OSDIC 8 is controlled by the room B.
And switch the room B OSD information to monitor TV5
Display on the screen.

Next, the above operation will be described with reference to the flowchart shown in FIG. Here, an example when the input source selector key is operated is shown. First, the user switches the operation mode of the room selector of the remote control commander 12 to the room A mode when used in the room A and to the room B mode when used in the room B. When the input source selector key is operated, the remote control commander 12, for example, [Room A-VIDE
O1] and [room B AUX]. Therefore, in step S1, the AV amplifier 1
Determines that the selector code has arrived, and if yes, proceeds to step S2, and determines whether or not the selector code is room A. If the answer to step S2 is yes, the operation proceeds to step S3, where the OSDIC 8 is automatically switched to the operation for the room A.
The SDIC 8 is switched to the room B.

As described above, the OSD display for each room is automatically displayed on the monitor TV of each room by the determination of the selector code from the remote control commander.

[0012]

According to the present invention, when the user operates the remote controller without being conscious of the operation, the OSD is displayed on the monitor of the room where the user is, and the user can know the information.
