2. Description of the Related Art A remote controller for a conventional television receiver is a device for controlling the television receiver at a position distant from the television receiver. In addition to the remote controller for the conventional television receiver,
Remote controls such as a remote controller with a mobile phone function, a remote controller with a PDA function, and a remote controller with a wristwatch function are known.

PDA is a Personal Digital Assistant
(Portable personal information terminal), an electronic device that fits in the palm of your hand, and is a terminal that implements some of the functions of a personal computer.

The broadcasting system is a broadcasting system such as a radio wave broadcasting system or the Internet broadcasting. Radio broadcasting is used for general terrestrial television receiver broadcasting, radio broadcasting,
It is a broadcasting format for broadcasting programs through radio waves, such as satellite broadcasting and digital satellite broadcasting. Internet broadcasting is a broadcasting mode in which programs are broadcast over the Internet.

Video viewing devices such as a television receiver and a video recording / playback device include one video viewing device and one dedicated remote controller.
In general, it is equipped with a stand, and when the dedicated remote controller is operated, the video viewing apparatus can be controlled from a remote place via a wireless signal such as an infrared signal or a radio signal.

When a user operates an image viewing device such as a television receiver or a video recording / reproducing device, it is generally operated by using a remote controller, and when a single television receiver is viewed by a plurality of users. In addition, when the channel, volume, etc. of the television receiver are operated using the remote controller, the user having the remote controller operates the remote controller. When a user who does not have a remote controller operates a channel or the like, it is necessary to rent the remote controller to the user who has the remote controller, and there is a drawback that lending and renting the remote controller is complicated each time.

In order to solve this drawback, a plurality of remote controllers may be used so that one video viewing apparatus can be operated from any of the remote controllers. in this case,
If it is possible to operate from any remote controller, it may cause competition for channels, and this competition for channels becomes a new drawback.

In order to solve this new drawback, Japanese Unexamined Patent Application Publication No. 2001-61110 discloses a method of giving priority to a remote control device to improve the operability of a television receiver, and a method of assigning it to a plurality of remote controls. There has been proposed a method of determining the operation content based on the total of the priorities.

The "priority order" in the conventional example is
Priority data is given to the remote controller, and the order is determined according to the given priority data. Further, the priority data is considered in the same way as the score, and the remote controller having the largest numerical value (score) has a higher priority. The number of requests for each channel is weighted by priority and added, and the channel with the most number of requests is displayed.

[0010]

[Patent Document 1] Japanese Patent Application Laid-Open No. 2001-611
According to the method described in Publication No. 10, when a single video viewing device is operated using a plurality of remote controllers, the priority order of each remote controller is fixed, so that even when no one is watching the video viewing device, the priority order is given priority. Only the remote controller with the highest priority can control the video viewing device, and therefore, when no one is looking at the video viewing device, use the remote control other than the remote control with the highest priority to view the video viewing device. There is a problem that you can not.

That is, when operating one video viewing device using a plurality of remote controllers, when no one is watching the video viewing device, the remote control of the user who wants to operate controls the video viewing device. There is a problem that the right cannot be given properly.

According to the present invention, when a single video viewing device is operated by using a plurality of remote controllers, when no one is looking at the video viewing device, the video viewing device is controlled by the remote controller of the user who desires the operation. It is an object of the present invention to provide a control device for a video viewing device, a control method therefor, a program, and a recording medium that can appropriately give the control right to operate.

[0013]

According to the present invention, when a plurality of remote controllers are used to operate one television receiver or a video viewing apparatus such as a video, any one of the plurality of remote controllers can be used as the video viewing apparatus. In an indefinite state in which the user does not have the control right to control, the control right is given to the remote controller that first operated.

Is a means for holding the control right of the remote controller, which had the control right before the power was turned off, for a predetermined period of time when the power is turned off, and for setting the state to an indefinite state after the above-mentioned predetermined period of time.

The control right management section 13 includes remote controllers RC1 to RC.
It manages which remote controller in C3 currently has control.

Next, the operation of the first embodiment will be described.

First, the operation when the first remote controller RC1 desires to acquire the control right in the unfixed state in the first embodiment will be described.

FIG. 2 is a flow chart showing an operation of operating a predetermined remote controller in the case of an undefined state in the first embodiment, and the operated remote controller acquires the control right.

In S101, a predetermined remote controller is used,
When an operation of turning on the power of the video viewing apparatus 20 or an operation of changing the channel is executed, the operation signal and the ID of the remote controller are input / output via the operation information input / output unit 1 and the control unit 4 of the remote controller. It is output from the unit 5.

The signal input / output unit 11 of the video viewing apparatus 20 receives the operation signal and the remote control ID (S102), and the control unit 12 interprets the operation content of the received operation signal (S102).
103), based on the received remote controller ID, the control unit 12 determines from which remote controller the operation information is received (S104, S110, S116).

When it is determined that the first remote controller RC1 is operated (S104), it is determined whether or not the first remote controller RC1 has the control right (S105).

3 and 4 are diagrams showing an example of the relationship between each remote controller and the presence / absence of control right possession in the above-mentioned embodiment.

In FIG. 3 and FIG. 4, when the numerical value of control right possession is 1, the remote controller whose numerical value is 1 has the control right and the remote controller whose numerical value is 0 does not have the control right. Is shown.

The state shown in FIG. 3 is the first remote controller RC.
Neither the first remote controller RC, the third remote controller RC3, nor the third remote controller RC3 has the control right, so that the state is undefined.

If none of the remote controllers have the control right (S
105, S106, S107), that is, it is determined that the operation (request) is performed by the first remote controller RC1 in the undefined state (S104), and thus the control right is given to the first remote controller RC1 (S108). ), The operation request by the first remote controller RC1 is reflected (S109).

As a result, the database of the control right management unit 13 changes to the state in which the first remote controller RC1 has the control right, as shown in FIG.

On the other hand, when it is determined whether or not the first remote controller RC1 has the control right (S105), if it is determined that the first remote controller RC1 has the control right, the video / audio output unit 21 The operation of the first remote controller RC1 is reflected (S
109).

When the first remote controller RC1 is not operated,
When the remote controller is operated (S104, S110),
The control right management unit 13 determines whether or not the second remote controller RC2 has the control right (S111).

Here, if none of the first remote controller RC1, the second remote controller RC, and the third remote controller RC3 has the control right (S111, S112, S11).
3) In the undetermined state, it is determined that the operation (request) has already been performed by the second remote controller RC2 (S110), so the control right is given to the second remote controller RC2 (S11).
4), the operation request by the second remote controller RC2 is reflected (S115).

First remote controller RC1 and second remote controller R
When C2 is not operated and the third remote controller is operated (S104, S110, S116), the third remote controller R
The control right management unit 13 determines whether or not C3 has the control right (S117).

Here, if any of the first remote controller RC1, the second remote controller RC, and the third remote controller RC3 has no control right (S117, S118, S11).
9) In the undetermined state, it is determined that the operation (request) has already been performed by the third remote controller RC3 (S116), so the control right is given to the third remote controller RC3 (S12).
0), the operation request by the third remote controller RC3 is reflected (S121).

On the other hand, if it is determined that the signal is not from any remote controller (S104, S110, S116), an error is displayed on the video / audio output unit 21 (S122).

According to the first embodiment, the control right can be given to the remote controller which is operated first from the state where the control right is not defined.

When there are a plurality of remote controllers, it is important to determine to which remote controller it is appropriate to give the control right to control the video viewing device 20, but according to the first embodiment, Assuming two states, one in which the control right for controlling the video viewing device 20 is given to one remote controller and an indefinite state in which no control right is given to any remote controller, the operation is performed in the indefinite state. A control right is given to the remote controller, and by this, the standard for exiting from the indeterminate state and exiting from the indeterminate state is clear.

Next, in the above embodiment, when the first remote controller RC1 has the control right, the first remote controller R1
The operation when C1 abandons the control right will be described.

FIG. 5 is a flow chart showing the operation in the above-mentioned embodiment when a predetermined remote controller has the control right and wishes to abandon the control right.

First, when the control right abandon button 3 provided on a predetermined remote controller is turned on (S201), the signal input / output unit 5 of the remote controller outputs an operation signal (specifically, abandon signal) and a remote controller ID. And the signal input / output unit 11 of the control device 10 receives the remote control signal and the remote control ID (S202).

Then, the control unit 12 interprets the operation content (S203) and determines from which remote controller the operation information is based on the received remote controller ID (20).

When it is determined that the first remote controller RC1 has been operated (S204), the control right management unit 13 determines whether the first remote controller RC1 has the control right, and the first remote controller RC1 controls. If it has the right (S205), it deprives the first remote controller RC1 of the control right (S20).
8).

When it is determined that the first remote controller RC1 has been operated (S204), the first remote controller does not have the control right (S205), and the second remote controller RC2 or the third remote controller RC3.
If the remote controller RC3 has the control right (S206,
In S207), a message such as "You do not have control right" is displayed on the video / audio output unit 21 (S223).

On the other hand, when it is determined that the first remote controller RC1 is not operated (S204) and the second remote controller RC2 is operated (S210), it is controlled whether or not the second remote controller RC2 has the control right. If the right management unit 13 determines that the second remote controller RC2 has the control right (S211),
The control right is stripped from the second remote controller RC2 (S21).
4).

When it is determined that the second remote controller RC2 is operated (S210), the second remote controller does not have the control right (S211), and either the first remote controller RC1 or the third remote controller RC1 is operated.
If the remote controller RC3 has the control right (S212,
In S213), a message such as "You do not have control right" is displayed on the video / audio output unit 21 (S223).

On the other hand, when it is determined that the third remote controller RC3 is operated without operating the first remote controller RC1 and the second remote controller RC2 (S204, S210) (S21).
6), the control right management unit 13 determines whether the third remote controller RC3 has the control right, and the third remote controller RC3
If has the control right (S217), the control right is deprived from the third remote controller RC3 (S220).

When it is determined that the third remote controller RC3 is operated (S216), the third remote controller does not have the control right (S217), and the first remote controller RC1 or the second remote controller RC3 is not operated.
If the remote controller RC2 has the control right (S218,
In step S219, a message such as "You do not have control right" is displayed on the video / audio output unit 21 (S223).

If it is determined that the signal is not from any remote controller (S204, S210, S216), an error is displayed on the video / audio output unit 21 (S222).

[Second Embodiment] The second embodiment of the present invention is an embodiment in which the control right is deprived after a predetermined period of time has passed since the power of the video viewing apparatus 20 was turned off. is there.

The configuration of the second embodiment is the broadcasting system BS.
The same as 1.

FIG. 6 is a flow chart showing the operation in the second embodiment when the power source is turned off by a method other than the remote controller when the predetermined remote controller has the control right.

First, it is determined whether or not the power source of the video viewing apparatus 20 is turned off by an operation other than the remote control (S30).
1) If it is determined that the power switch 22 of the video viewing device 20 is turned off, the control unit 12 turns off the power of the video viewing device 20 (S302).

After the power of the video viewing apparatus 20 is turned off (S302), the timer of the control right management unit 13 is started (S303), and the elapsed time after the timer is started is measured (S3).
04), the control right management unit 13 determines whether or not a time longer than a preset control right holding time has elapsed (S30).
5) If the time longer than the control right holding time has not elapsed, the process returns to step S304 and the time is measured.

If the time longer than the control right holding time has passed (S305), the remote controller having the control right is specified (S306, S308, S310). If the first remote controller RC1 has the control right (S306),
The control right is stripped from the first remote controller RC1 (S30
7) If the second remote controller RC2 has the control right,
(S308), the second remote controller RC2 is deprived of the control right (S309), and if the third remote controller RC1 has the control right (S310), the third remote controller RC3 is deprived of the control right (S311). ),finish.

If none of the remote controllers RC1, RC2 and RC3 has the control right, the power-off operation of the video viewing device 20 is terminated. At this time, none of the remote controllers have the control right, so that the state is undefined as shown in FIG.

According to the second embodiment, the person who does not have the control right can obtain the control right by the video viewing device 20.
When the power of the video viewing apparatus 20 is turned off, the remote controller, which has the control right immediately before the power of the video viewing apparatus 20 is turned off, holds the control right within a certain time after the power of the video viewing apparatus 20 is turned off. , By this, control is not easily transferred.

That is, in a television receiver or the like, the power switch provided on the main body can be used to turn off the power of the television receiver. For example, when a user who owns this remote controller leaves the television receiver while the predetermined remote controller has the control right, the power of the television receiver may be turned off. It is useless to give the remote controller control rights.

That is, when the power of the image viewing apparatus 20 is turned off by an operation other than the remote control, it is often unnecessary to give the remote control the control right. Therefore, it is considered preferable to leave the image viewing device 20 in an indefinite state when the power is not turned on by an operation other than the remote control.

However, it is conceivable that the power may be accidentally turned off, or the power may be turned off for a short time during a telephone call. In such a case, the control right should be stripped each time. On the contrary, it is inconvenient. Therefore,
In the second embodiment, the power may be accidentally turned off, and in preparation for turning off the power for a short time during a telephone call, if the power is turned off continuously for a predetermined fixed time or longer,
The control right held until immediately before that is deprived, and the above-mentioned predetermined fixed time is counted by the timer (S303, S304,
S305), if there is any operation from the remote controller having the control right before the lapse of the certain period of time, the power is not turned on, for example.

[Third Embodiment] A third embodiment of the present invention is an embodiment in which, when the power of the video viewing apparatus is turned off by operating the remote controller, the control right of the remote controller is stripped.

The configuration of the third embodiment is similar to that of the broadcasting system BS1 shown in FIG.

FIG. 7 is a flow chart showing the operation of the third embodiment of the present invention. When the power of the video viewing device 20 is turned off by the operation of the remote controller, the operation of depriving the control right of the remote controller will be described. It is a flowchart shown.

The flowchart shown in FIG. 7 is basically the same as the flowchart shown in FIG.
Only 409, S415, and S421 are different from FIG. Therefore, common parts are given the same step numbers as in FIG. 5, only different parts are given step numbers in the 400s, and by displaying in this way, the different parts are described at a glance. I am doing it.

First, when the power switch 6 provided in a predetermined remote controller is turned off (S401), the signal input / output unit 5 of the remote controller outputs the operation signal and the remote controller ID, and the signal input / output of the control device 10 is performed. The unit 11 receives the remote control signal and the remote control ID (S202).

Then, the control section 12 interprets the operation content (S203) and determines which remote controller the operation information is from based on the received remote controller ID (20).
4, S210, S216).

When it is determined that the first remote controller RC1 is operated (S204), the control right management unit 13 determines whether the first remote controller RC1 has the control right, and the first remote controller RC1 controls. If it has the right (S205), the control right is stripped from the first remote controller RC1 (S20).
8), turn off the power of the video viewing device 20 (S40).
9).

When it is determined that the first remote controller RC1 is operated (S204), the first remote controller does not have the control right (S205), and the second remote controller RC2 or the third remote controller RC2 is operated.
If the remote controller RC3 has the control right (S206,
In S207), a message such as "You do not have control right" is displayed on the video / audio output unit 21 (S223).

On the other hand, if it is determined that the first remote controller RC1 is not operated (S204) and the second remote controller RC2 is operated (S210), it is controlled whether the second remote controller RC2 has the control right. If the right management unit 13 determines that the second remote controller RC2 has the control right (S211),
The control right is stripped from the second remote controller RC2 (S21
4), turn off the power of the video viewing device 20 (S41)
5).

When it is determined that the second remote controller RC2 is operated (S210), the second remote controller does not have the control right (S211), and either the first remote controller RC1 or the third remote controller RC1 is operated.
If the remote controller RC3 has the control right (S212,
In S213), a message such as "You do not have control right" is displayed on the video / audio output unit 21 (S223).

On the other hand, when it is determined that the third remote controller RC3 is operated without operating the first remote controller RC1 and the second remote controller RC2 (S204, S210) (S21).
6), the control right management unit 13 determines whether the third remote controller RC3 has the control right, and the third remote controller RC3
Has the control right (S217), the control right is deprived from the third remote controller RC3 (S220), and the video viewing apparatus 20 is powered off (S421).

When it is determined that the third remote controller RC3 is operated (S216), the third remote controller does not have the control right (S217), and the first remote controller RC1 or the second remote controller RC2 is not operated.
If the remote controller RC2 has the control right (S218,
In step S219, a message such as "You do not have control right" is displayed on the video / audio output unit 21 (S223).

If it is determined that the signal is not from any remote controller (S204, S210, S216), an error is displayed on the video / audio output unit 21 (S222).

According to the third embodiment, when the power switch 6 provided on the remote controller is turned off, it is determined that the remote controller which has turned off the power switch 6 provided on the remote controller has abandoned the control right. When the control right is desired to be abandoned, the control right can be easily abandoned and the control right can be easily managed.

The above embodiment can be understood as a program invention. That is, in the above-described embodiment, a plurality of remote controllers are associated with one video viewing device, and only one remote controller among the plurality of remote controllers operates in the program for controlling the video viewing device. None of the remote controllers have the control right to control the video viewing device, and the remote controller ID detection procedure for detecting the ID of the first operated remote controller in an indefinite state and the remote controller having the detected ID. 3 is an example of a program that causes a computer to execute the control right granting procedure for granting the control right.

In this case, the program determines that the remote controller having the control right has abandoned the control right and that the remote controller having the control right has abandoned the control right. It is a program that causes a computer to execute an indefinite state setting procedure for setting an indefinite state when judged by the abandonment determination procedure.

The abandonment determination procedure is performed when the remote controller having the control right turns off the power of the video viewing apparatus or when the control right abandon button provided on the remote controller is turned on. This is a procedure for determining that the remote controller having the control right has abandoned the control right.

Further, in the indefinite state setting procedure, when the power of the video viewing apparatus is turned off by an operation other than the operation of the remote controller, the user has the control right immediately before the power is turned off for a predetermined fixed time. This is a procedure of holding the control right of the remote controller and setting it to an indefinite state after the lapse of the predetermined time.

In addition, the above-mentioned program is applied to FD (floppy (registered trademark) disk), CD (compact disk), HD (hard disk), DVD (Digital Ver.
It may be recorded on a recording medium such as a satileDisc) or a semiconductor memory.

Although each of the above embodiments relates to the radio wave broadcasting system, the above embodiments can be applied to not only radio wave broadcasting but also Internet broadcasting other than radio wave broadcasting, and the remote control information is stored. The above-described embodiment can be applied regardless of where the mechanism is installed.

Even if the remote controller has two remote controllers,
The above embodiment can be applied to the case where there are one or more.

In radio wave broadcasting such as terrestrial television, one channel is assigned to one broadcasting station, and a program to be viewed can be selected by selecting a channel. Can change the channel. On the other hand, in Internet broadcasting, the equivalent of a channel is a URL.
A program can be selected by specifying. In the above embodiment, the TV channel is described as an example for easy understanding, but the present invention is not limited to a radio wave broadcasting system such as a terrestrial television.
