Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an AV system comprising a combination of a universal type remote controller and an AV (audio video) device, and more particularly to an input selector display switching function of the AV device.

[0002]

2. Description of the Related Art Conventionally, by operating an input selector switching key of a universal type remote control commander capable of controlling a plurality of AV (audio video) devices (amplifiers and receivers) of a plurality of manufacturers,
In an AV device having a function of switching an input selector for selecting an input source device, the name of the selector is determined from the beginning. For example, if there are four video selectors VIDEO1 to VIDEO4, these selectors are used. When selected with the selector switch key on the remote control or the selector switch key attached to the device body,
The display section provided on the device body or the remote control displays "VI
"DEO1" to "VIDEO4" were displayed. Therefore, when different types of video playback devices are connected to the video-based selector, the user needs to select the selector “VIDEO”.
It is necessary to remember the type of the video playback device connected to "1" to "VIDEO4" and switch the selector.

On the other hand, as described above, the name of the selector is "V
IDEO1 "-" VIDEO4 "
For example, "VCR", "LD", "CABL" which means a video cassette recorder, a laser disc player, a cable television, and a satellite broadcast tuner, respectively.
E "," SAT "or other fixed names on the display
When displaying character characters such as "R", "LD", "CABLE", and "SAT", the user can display which type of device is connected to which selector only when using the connected device as displayed. The parts are obvious at a glance and can be used without any problems. However, in such a case, it is difficult to use, because the number of connectable devices is limited to four. Also, for example, the selector “SAT”
It is also possible to connect a device regardless of the name of the selector by connecting a VCR to the device, but in this case, the user must remember the type of device connected to the selector, as described above. The problem arises.

Further, when the operation surface (device to be operated) of the universal type remote control commander is switched, the display of the amplifier or the receiver indicates the remote control operation surface. When the universal type remote control commander can control a plurality of devices and preset codes of the same type of device can be set, for example, when setting three different “VCRs”, the operation surface of the remote control commander is different. Even when switching to the VCR, the same character character of "VCR" is displayed on the display of the remote control commander main body for indicating the status of the remote control to the user and the display of the AV amplifier and the receiver operated by the remote control commander. There is a problem that it is very difficult to understand because only the display is output.

[0005]

FIG. 1 is a block diagram showing an embodiment of an AV system according to the present invention. In FIG. 1, 1
Denotes an AV device, which includes a microcomputer 2, a key operation unit 3, a remote control signal receiving (light receiving) unit 4, and a display unit 5.
And a selector switching unit 6. Reference numeral 11 denotes a remote control commander #, which includes a microcomputer 12, a key operation unit 13, a remote control signal transmission (light emission) unit 14, and a display unit 15. In order to operate a plurality of AV devices of a plurality of manufacturers, the remote control commander 11 checks a code (hereinafter, referred to as a preset code) of the used AV device from a preset code table, sets the code, and uses the code. A remote control that enables the operation of the AV equipment being used is generally called a universal type remote control.

[0010] In the AV equipment 1 capable of switching input selectors by using such a universal type remote control commander 11, the remote control commander 1
In the case where the preset code 1 of the input source device connected to the input selector of the AV device 1 can be set corresponding to the input selector, the input selector switching key of the key operation unit 13 is operated. At this time, the first remote control code for selector switching and the second remote control code indicating the type of the input source device preset in the selected selector are transmitted by remote control (light emission).
The output from the unit 14 causes the AV device 1 receiving the remote control code to display the selected selector and the type of the input source device in which the preset code is set on the display unit 5. For example, when the selector switch key of the remote control commander 11 is operated, two first and second remote control codes, "selector VIDEO1" and "type"
VCR "is output. The AV device 1 receives the two remote control codes, switches to the input selector “VIDEO 1” under the control of the microcomputer 2, and displays the character “VCR” on the display unit 5.

[0011] AV operation by key operation of the remote control commander 11
When the selector of the device 1 is switched, “VCR” or the like can be displayed on the display unit 5 by outputting the two remote control codes as described above. Even if the input selector switching key is operated, once the selector has been switched by the remote control commander 11, the microcomputer 2 of the AV device 1 sets the selector "VIDEO1" to "VC1".
"R" is stored, and after that, when "VIDEO1" is selected by operating the input selector switching key of the AV device 1, "VCR" is displayed on the display unit 5. It is possible. Also,
When a new preset code of a different AV device is set in “VIDEO 1”, the display is changed to a new remote control code.

In step S8, it is determined whether or not the received first remote control code is the selector VIDEO4.
If no, end the work. In S9, the selector is switched to VIDEO4, and then the process proceeds to S10. S10
Then, it is determined whether or not the received second remote control code is the preset type VCR. If yes, the process proceeds to S11, where the character "VCR" is displayed on the display unit of the AV device main body, and then the operation is terminated. If the answer to S10 is no, the process proceeds to S12. In S12, the received second
It is determined whether or not the remote control code is the preset type LD. If yes, the process proceeds to S13, where the character "LD" is displayed on the display unit of the AV device main body, and then the operation is terminated. If the answer to S12 is no, the process proceeds to S14.

In S14, it is determined whether or not the received second remote control code is a preset type DVD (digital versatile disc). If the answer is YES, the process proceeds to S15, where the character character "DVD" is displayed on the display unit of the AV device main body. Is displayed, and then the operation is completed. If the answer to S14 is no, the process proceeds to S16. In S16, it is determined whether or not the received second remote control code is the preset type SAT. If the answer is YES, the process proceeds to S17, where the character character "SAT" is displayed on the display unit of the AV device main body.
Then, the operation is completed. If the answer in S16 is no, S18
Proceed to. In S18, it is determined whether or not the received second remote control code is a preset type DSS (Digital Satellite System).
The character character "DSS" is displayed on the display unit of the AV device main body, and then the operation is terminated. If the answer to S18 is no, the process proceeds to S20. In S20, it is determined whether or not the received second remote control code is the preset type CABLE. If the answer is YES, the process proceeds to S21, where the character "CABLE" is displayed on the display unit of the AV device body, and then the operation is terminated. . If the answer to S20 is no, the operation is terminated.

As described above, when the input selector is switched, the input selector is displayed on the basis of the output code of the remote controller, so that the user can easily know which selector is connected to which AV equipment. . "VCR", "LD",
Since it is not necessary to give a fixed name such as "CABLE" from the beginning, the type of AV device to which the user can connect is not limited.

Next, when the remote control commander 11 can control a plurality of devices and can set preset codes of the same type of device, for example, three
When the “VCR” operation surface is selected by the remote control commander 11 after the setting of one “VCR”, the display is displayed on three “VCR” operation surfaces as shown in the following first and second embodiments. Of which, it was easier to understand which operation surface was selected. Embodiment 1 FIG. When displaying that the operation surface of the remote control has been switched, the display is erased (blinking) for an arbitrary time to make it easy to recognize that the operation surface of the remote control has been switched.

FIG. 3 is a flowchart for explaining the above operation. First, in step S31, it is determined whether or not an operation surface switching key of the remote control commander 11 has been input. For example, if the selector switch key is operated following the operation of the shift key of the key operation unit 13, the remote mode VCR, the remote mode LD,. . . And the operation surface of the commander 11 is for VCR, LD
for,. . The remote control code representing each remote mode is transmitted from the remote control transmitting unit 14. (If only the selector switch key on the operation surface of the remote control commander 11 is operated, for example, the selector code
Two remote control codes such as VIDEO1 and preset type VCR are transmitted, and the operation follows the flowchart shown in FIG. 2, but the flowchart of FIG. 3 does not proceed. Therefore, if the answer to S31 is yes, the process proceeds to S32, and if no, the process proceeds to S46.

In S32, a timer for displaying a remote control operation surface (for example, a 5-second timer) is started.
Proceed to 3 to start a display erasing timer (for example, a 200 millisecond timer). Next, in S34, the microcomputer 2 of the AV device 1 determines whether or not the operation surface of the remote control commander 11 has been switched to the VCR based on the remote code received by the remote control signal receiving (light receiving) unit 4. For example, the process proceeds to S35, where the character character information of "VCR" is stored in the display buffer in the microcomputer 2, and then the process proceeds to S46. If the answer to S34 is no, the process proceeds to S36, where the microcomputer 2
Determines whether or not the operation surface of the remote control commander 11 has been switched to LD in the same manner as in the operation of S34. If yes, the process proceeds to S37, and the character buffer information of "LD" is stored in the display buffer in the microcomputer 2. And store
Next, the process proceeds to S46. If the answer to S36 is NO, the process proceeds to S38, and similarly, the microcomputer 2 determines whether or not the operation surface of the remote control commander 11 has been switched to DVD. If the answer is YES, the process proceeds to S39, and the display in the microcomputer 2 is performed. The character character information of "DVD" is stored in the buffer for the program, and then the process proceeds to S46.

If the answer to S38 is NO, the process proceeds to S40, and similarly, the microcomputer 2 determines whether or not the operation surface of the remote control commander 11 has been switched to SAT. The character character information of "SAT" is stored in the display buffer in the box, and the process proceeds to S46. If the answer to S40 is NO, the process proceeds to S42, and similarly, the microcomputer 2 determines whether or not the operation surface of the remote control commander 11 has been switched to DSS, and if YES, the process proceeds to S43.
"DS" is displayed in the display buffer in the microcomputer 2.
The character character information of "S" is stored, and then the process proceeds to S46. If the answer to S42 is NO, the process proceeds to S44, and the microcomputer 2 similarly determines whether or not the operation surface of the remote control commander 11 has been switched to CABLE. The character buffer information of "CABLE" is stored in the buffer for processing, and then the process proceeds to S46. If the answer to S44 is no, the process proceeds to S46.

Then, in S46, it is determined whether or not the display erasing timer is counting.
The display unit 5 of the main body of the V device 1 is cleared and the display is turned off. S46
If the answer is no, the process proceeds to S48 to determine whether or not the operation surface display timer is counting. If the answer to S48 is yes, the process proceeds to S49, where the character character information stored in the display buffer is called and the display unit 5 of the main body of the AV device 1 is called.
To supply and display. If the answer to S48 is NO, the process proceeds to S50, where the current selector is displayed on the display unit 5 of the AV device 1 main body.

Therefore, when the input selector is switched, the display content of the display unit 5 blinks for a predetermined time (200 milliseconds in this example), so that the user is warned that the operation surface of the remote control commander 11 has been switched. .

Embodiment 2 FIG . When multiple presets of the same type of input source device are performed, when the remote controller or the AV device of the amplifier or the receiver having the function of receiving the output code of the remote controller changes the operation surface of the remote control commander, For example, a number is added to the display “VCR” on the display unit 5 of the device 1 and displayed. The microcomputer 12 built in the remote control commander 11 detects that there are a plurality of presets of the same type of input source device, and when the remote control operation surface is switched, the display shown on the display unit 5 of the AV device 1 is displayed as “VCR1 "
Differentiate with “VCR2”, “VCR3”, etc. Also,
By changing the output code when switching the remote control operation surface, or by including a code indicating a number in multiple output codes, these differences are broken down by the amplifier or receiver, and the display is the same as that of the remote control "VCR1", "VCR
By setting “2” and “VCR3”, it is easy to recognize that the operation surface of the remote controller has been switched.

FIG. 4 is a flowchart for explaining the above operation. In this example, when a plurality of presets of the same type of input source device are set, “N” indicating the N-th setting is added to the display of the display unit 5. First, in step S51, the remote control commander 11
It is determined whether or not the operation surface switching key has been input. If yes, the process proceeds to S52, and if no, the process proceeds to S71. In S52,
Timer for remote control operation surface display (for example, 5 seconds timer)
Is started, and then the process proceeds to S53. In S53, AV
The microcomputer 2 of the device 1 determines whether or not the operation surface of the remote control commander 11 has been switched to the VCR based on the remote code received by the remote control signal receiving (light receiving) unit 4. Check the number of the VCR and set "N", then S5
The program proceeds to S5, where the character character information of "VCR" N "" is stored in the display buffer in the microcomputer 2, and then the procedure proceeds to S71.

If the answer to S53 is NO, the process proceeds to S56, and the microcomputer 2 determines whether or not the operation surface of the remote control commander 11 has been switched to the LD similarly to the operation at S53, and if YES, the process proceeds to S57. , What L
D, and sets “N”. Then, the process proceeds to S58, where “L” is stored in the display buffer in the microcomputer 2.
The character information of D "N" is stored.
Proceed to 1. If the answer to S56 is NO, the process proceeds to S59, and the microcomputer 2 similarly executes the remote control commander 1
1 to determine whether the operation surface has been switched to the DVD,
If yes, proceed to S60, check the number of the DVD and set "N", and then proceed to S61 to display "DVD" N "" in the display buffer in the microcomputer 2.
Is stored, and then the process proceeds to S71.
If the answer to S59 is NO, the process proceeds to S62, and similarly, the microcomputer 2 determines whether or not the operation surface of the remote control commander 11 has been switched to the SAT, and if YES, the process proceeds to S63 to determine the number of the SAT. Check to set "N", and then proceed to S64 to store the character character information of "SAT" N "" in the display buffer in the microcomputer 2, and then proceed to S71.

If the answer to S62 is NO, the process proceeds to S65, and similarly, the microcomputer 2 determines whether or not the operation surface of the remote control commander 11 has been switched to the DSS. DSS is set and "N" is set. Then, the flow advances to S67 to display "DSS" in the display buffer in the microcomputer 2.
The character character information of "N" is stored, and then S71
Proceed to. If the answer to S65 is NO, the process proceeds to S68, and the microcomputer 2 similarly controls the remote control commander 11
It is determined whether or not the operation surface has been switched to CABLE. If yes, the process proceeds to S69, where the CABLE number is checked and “N” is set, and then the process proceeds to S70.
"CAB" is displayed in the display buffer in the microcomputer 2.
LE “N” character character information is stored, and then S
Go to 71. If the answer to S68 is no, the process proceeds to S71.

Next, in S71, it is determined whether or not the operation surface display timer is counting. If the determination is yes, the process proceeds to S72, where the character character information stored in the display buffer is called and the display unit 5 of the main body of the AV device 1 is called. To supply and display. If the answer to S71 is NO, the process proceeds to S73, and the current selector is displayed on the display unit 5 of the AV device 1 body. Therefore, for example, when four VCRs are preset as input source devices, and when the operation surface of the remote control commander 11 is set for the third VCR, the display unit 5
Is displayed as "VCR3".

Although the above description has shown the case of switching the remote control operation surface, it has other display functions, and the display itself does not change. The present invention can be applied.

As described above, it is easy to see that the operation surface of the remote controller has been switched. In addition, since it is known that the operation surface of the remote controller has been switched even with the same type of device, it becomes easy to control a plurality of devices of the same type with one remote control.
