For example, the setting program 114a authenticates the user to the CPU 111 using the authentication information input by the key operation unit 1 and the setting authentication information set in advance. When the user is authenticated, the setting program 114a It is a program for realizing a function for allowing a user to set a setting time that can be used.
Specifically, the CPU 111 causes the display unit 9 to display a user authentication screen illustrated in FIG. 4 when executing the setting program 114a. On the game authentication screen of FIG. 4, the user operates the key operation unit 1 and inputs authentication information such as a password and a password. When the authentication information is input by the user on the authentication screen, the CPU 111 determines whether or not the input authentication information matches the setting authentication information stored in advance in the setting authentication information storage unit 1132a. If they match, it is determined that the user has been authenticated.

When the user is authenticated, the CPU 111 further causes the display unit 9 to display a game setting screen illustrated in FIG. In the game setting screen of FIG. 5, the user operates the key operation unit 1 to input and set a setting time during which the game machine 200 can be used. In FIG. 5, for example, a continuous play time in which the game machine 200 can be used continuously (for example, 1 hour) and a play time in a day in which the game machine 200 can be used during the day (for example, 3 hours) can be set separately.
Further, the user sets a method for restricting the use of the game machine 200 when the game machine 200 is used beyond the set time set by the user on the game setting screen of FIG. In the game setting screen of FIG. 5, for example, a desired method can be selected from “forced termination”, “video / audio mute”, “video mute”, “audio mute”, and “message display”. Yes. A plurality of methods may be selectable.
Furthermore, in the game setting screen of FIG. 5, the external input terminal 41 to which the cable C of the game machine 200 is connected can be selected and set from the game machine compatible external input terminals 41 provided in the interface unit 4. Yes.

The CPU 111 stores the setting time, the restriction method, and the external input terminal 41 for connecting the game machine 200 set on the game setting screen of FIG.
The CPU 111 functions as an authentication unit and a setting unit by executing the setting program 114a.

The measurement program 114b is a program for causing the CPU 111 to measure the usage time of the game machine 200, for example.
Specifically, when video / audio data played back on the game machine 200 is input via the cable C of the game machine 200 connected to the external input terminal 41 and the use of the game machine 200 is started, The CPU 111 causes the timer 112 to measure the elapsed time since the use of the game machine 200 is started.
The CPU 111 functions as a measurement unit together with the time measuring unit 112 by executing the measurement program 114b.

For example, the determination program 114c causes the CPU 111 to realize a function of determining whether or not the usage time of the game machine 200 measured by the execution of the measurement program 114b exceeds the set time set by the setting program 114a. It is a program.
Specifically, the CPU 111 refers to the setting storage unit 1132b that stores the setting time set by the user on the game setting screen (see FIG. 5) in the execution of the setting program 114a while the game machine 200 is being used. Then, it is determined whether or not the usage time of the game machine 200 measured by the timer unit 112 exceeds a set time (for example, 1 hour (continuous play time) or 3 hours (play time of one day)). When the user uses the game machine 200 beyond the set time, the CPU 111 determines that the usage time of the game machine 200 has exceeded the set time for using the game machine 200.
The CPU 111 functions as a determination unit by executing the determination program 114c.

The use restriction program 114d determines, for example, that the usage time of the game machine 200 measured by the execution of the measurement program 114b exceeds the set time set by the execution of the setting program 114a by the CPU 111 executing the determination program 114c. This is a program for realizing a function of restricting the use of the game machine 200 connected to the external input terminal 41 when it is executed.
Specifically, when the CPU 111 determines that the usage time of the game machine 200 has exceeded the set time in which the game can be used, the CPU 111 is set by the user on the game setting screen (see FIG. 5) in the execution of the setting program 114a. The setting storage unit 1132b that stores the restriction method is referred to, and processing for restricting use of the game machine 200 is performed. That is, for example, when the user sets “forced termination” on the game setting screen, the CPU 111 does not accept a signal from the game machine 200 and makes the game machine 200 unusable. Further, for example, when the user sets “video / audio mute”, the CPU 111 mutes the video / audio data input from the game machine 200 in a predetermined mute circuit, and outputs the video / audio of the game. Do not output. Further, for example, when the user sets “message display” on the game setting screen, the CPU 111 adds OSD data to the video signal output to the display unit 9 by the OSD circuit 8, and sets “setting”. A message such as “Time has expired. Please stop using the game machine 200.” is displayed on the display unit 9.
The method of restricting the use of the game machine 200 is not limited to the above-described video / audio mute and message display, and any process that prevents the normal use of the game machine 200 may be used. For example, a process of automatically turning off the power of the television receiver 100 may be used. Further, for example, a process of outputting a voice message when a parent inputs a voice message for a child in advance and the child uses the game machine 200 beyond a set time may be performed.
Moreover, you may alert | report to that effect before the predetermined time which passes set time (for example, 1 minute before).
The CPU 111 functions as a use restriction unit by executing the use restriction program 114d.

The insertion / removal monitoring program 114e is a program for causing the CPU 111 to realize a function of monitoring the insertion / removal of the cable C connected to the external input terminal 41 based on an on / off signal output from the switch 42, for example.
Specifically, the CPU 111 monitors the insertion / extraction of the external input terminal 41 to which the cable C of the game machine 200 is connected based on an on / off signal from the switch 42 provided on the external input terminal 41. When the user disconnects the cable C of the game machine 200 from the external input terminal 41 and the switch 42 provided in the external input terminal 41 is turned off, an off signal is output from the switch 42 to the CPU 111, and the CPU 111 Determines that the cable C of the game machine 200 has been disconnected from the external input terminal 41.
The CPU 111 functions as an insertion / removal monitoring unit by executing the insertion / removal monitoring program 114e.

For example, when the CPU 111 determines that the cable C has been disconnected from the external input terminal 41 by executing the insertion / extraction monitoring program 114e, the restriction program 114f is subsequently connected to the game machine 200 (electronic device) connected to the external input terminal 41. ) Is a program for realizing a function that restricts the use of.
Specifically, when the CPU 111 determines that the cable C of the game machine 200 is disconnected from the external input terminal 41 (for example, the composite terminal 41c) to which the game machine 200 is connected, the game machine included in the interface unit 4 is thereafter provided. The use of electronic devices such as the game machine 200 inserted into the corresponding external input terminal 41 (for example, the S terminal 41a, the D terminal 41b, the composite terminal 41c, and the component terminal 41d) is restricted.
As a method of restricting the use of the game machine 200, for example, a method similar to the method of restricting the use of the game machine 200 executed by the use restriction program 114d when a set time for using the game machine 200 is exceeded. Use. That is, for example, the CPU 111 refers to the setting storage unit 1132b that stores the restriction method set by the user on the game setting screen (see FIG. 5) in the execution of the setting program 114a, and is stored in the setting storage unit 1132b. Based on a restriction method set in advance by the user, a process for restricting the use of an electronic device such as the game machine 200 newly connected to the external input terminal 41 compatible with the game machine 200 is performed.
Further, for example, the CPU 111 shortens the set time set by executing the setting program 114a, and when the set time is exceeded, the use of the game machine 200 newly connected to the external input terminal 41 corresponding to the game machine is used. May be limited. Specifically, for example, the newly connected game machine 200 can be used only for a time (for example, 10 minutes) that is stored in the setting storage unit 1132b and is shorter than the setting time preset by the user. When the time is exceeded, the use is restricted based on the restriction method preset by the user and stored in the setting storage unit 1132b.
The CPU 111 functions as a limiting unit by executing the limiting program 114f.

Next, the use restriction processing of the game machine 200 performed in the television receiver 100 will be described with reference to the flowchart of FIG.
First, when the use of the game machine 200 is started in step S1 of FIG. 6, in step S2, the CPU 111 causes the time measuring unit 112 to start measuring the use time after the use of the game machine 200 is started. .
Next, in step S <b> 3, the CPU 111 refers to the setting storage unit 1132 b in which the setting time set in advance by the user is stored, and determines whether or not the usage time of the game machine 200 has exceeded the setting time. In step S3, when the CPU 111 determines that the usage time of the game machine 200 does not exceed the set time (step S3; No), the process proceeds to step S5. On the other hand, when the CPU 111 determines in step S3 that the usage time of the game machine 200 has exceeded the set time (step S3; Yes), a setting storage unit 1132b in which a restriction method set in advance by the user is stored in step S4. The use of the game machine 200 is restricted based on the restriction method, and the process proceeds to step S5.

In step S <b> 5, the CPU 111 determines whether or not the cable C is disconnected from the external input terminal 41 to which the game machine 200 is connected based on an on / off signal from the switch 42 provided in the external input terminal 41. If the CPU 111 determines that the cable C is not disconnected (step S5; No), it returns to step S3 and repeats the above processing. On the other hand, if it is determined that the cable C is disconnected (step S5; Yes), it proceeds to step S6. .
In step S <b> 6, the CPU 111 determines whether or not a new electronic device is connected to the game machine compatible external input terminal 41 provided in the interface unit 4 based on an on / off signal from the switch 42 provided in the external input terminal 41. Judgment. When CPU 111 determines in step S6 that there is no newly connected electronic device (step S6; No), it repeats the process of step S6. On the other hand, if it is determined in step S6 that there is a newly connected electronic device (step S6; Yes), in step S7, the use of the electronic device such as the newly connected game machine 200 is restricted, and this processing is performed. Exit.

By executing the insertion / removal monitoring program 114e, the insertion / removal of the cable C connected to the external input terminal 41 is monitored based on the on / off signal output from the switch 42. When it is determined that the cable C is disconnected from the external input terminal 41 by the execution, the use of the game machine 200 (electronic device) connected to the external input terminal 41 is restricted thereafter. In addition, user authentication information is input by the key operation unit 1, and user authentication is performed by the authentication information input by the key operation unit 1 and preset setting authentication information by executing the setting program 114a. In addition, a set time during which the game machine 200 can be used is set by the user, the use time of the game machine 200 is measured by executing the measurement program 114b, and measured by executing the measurement program 114b by executing the determination program 114c. It is determined whether or not the usage time of the game machine 200 to be executed exceeds the set time set by the execution of the setting program 114a, the execution of the measurement program 114b is executed by the execution of the determination program 114c by the execution of the use restriction program 114d. The usage time of the game machine 200 measured by the If it is determined that exceeds the set set time by the execution of the program 114a, the use of gaming machine 200 connected to the external input terminal 41 is limited. Furthermore, the restriction program 114f shortens the setting time set by executing the setting program 114a, and the setting program 114a enables setting of the setting time when the user is authenticated.

Therefore, when the game machine 200 is used beyond the set time set by the user, the use of the game machine 200 is restricted.
Furthermore, when the user disconnects the cable C of the game machine 200 connected to the external input terminal 41 from the external input terminal 41, the use of an electronic device such as the game machine 200 connected to the external input terminal 41 after that is used. Is limited. That is, when the user once unplugs the cable C of the game machine 200 and inserts it again into the same external input terminal 41, or when the user inserts it into another external input terminal 41, the game machine 200 thereafter. Cannot be used normally, and unauthorized use beyond the set time is more reliably prevented. Therefore, in a display device that is used by connecting the game machine 200, for example, unauthorized use performed by operating the external input terminal 41 connected to the game machine 200 can be more reliably prevented.

  In addition, only when the user authentication is performed based on the input user authentication information, the set time in which the game machine 200 can be used can be set, and the set time is changed by an unauthorized person. Can be prevented and unauthorized use of the game machine 200 can be more reliably prevented.
