[Embodiment] Referring to FIG. 1, a television set 100 includes a signal receiving unit 10, a multiplexer 20, a playback unit 30, an input unit 40, a storage unit 50, a controller 60, a judging unit 70, and a counter 80. [0015] The signal receiving unit 10 is configured to receive a multi-channel signal source. In this embodiment, the signal receiving unit 10 is an antenna, and the signal source is a broadcast television signal of a multi-channel. 098144169 Form No. A0101 Page 5 of 15 0982075558-0 201122891 [0016] The multiplexer 20 is coupled to the signal receiving unit 10 for selecting one of the multiple signal sources received by the signal receiving unit 10 to provide The playback unit 30 plays. [0017] The television set 100 is locked by a function module such as the multiplexer 20, the input unit 40, the storage unit 50, the controller 60, the determination unit 70, and the counter 80. The following describes in detail how the television set 100 is locked in conjunction with the functional modules. [0018] The storage unit 50 stores a preset password, a lock time, and the number of times the password is input. The default password, lock time, and number of password entries can be set by the TV manufacturer before leaving the factory, or can be set by the user according to the habit. [0019] In the present embodiment, the lockup time is set according to the boot time. The determining unit 70 is configured to determine whether the time when the TV set 00 is turned on meets the preset locking time, and when it is determined that the preset locking time is met, a trigger signal is generated. For example, when the user wants to pass his permission every time the power is turned on, the locking time can be set to the power-on time, that is, the television 100 - power on, and the determining unit 70 generates the trigger signal. When the user limits the time range of 22: 00~00:00 to allow the TV to play the program, the locking time can be set to 22: 00~00:00, that is, the television 100 is at 22: 00~0 (h00 this time period) At some point in time, the determining unit 70 generates the trigger signal. [0020] The controller 60 should trigger the signal, and output a user interface prompting the user to input a password to request the user to input a password. The user interface 200 is as shown in FIG. 2. [0021] The input unit 40 is configured to input a password for the user. [0022] The determining unit 70 is configured to determine whether the password input by the user is the same as the preset password. Page 6 of 15 pages 098144169 Form No. A0101 201122891 ❹ [0023] 00 [0025] matching to determine whether the password input by the user is correct. That is, the determining unit 70 compares the input password with the preset password, and when the password input by the user is the same as the preset password, determining that the password input by the user is different from the preset password. Matching, that is, the input password is correct, otherwise, the input password is judged to be wrong. When the judging unit 70 judges that the input password is incorrect, the trigger signal is output to the controller 60 again to request the user to input the password. At the same time, the counter 80 starts counting to count the number of times the user inputs the wrong password. The determining unit 70 is further configured to determine whether the number of times the user inputs the wrong password exceeds a preset number of times, and when it is determined that the number of times the user inputs the wrong password exceeds the predetermined number of times, A shutdown command is generated. The controller 60 should close the instruction to turn off the multiplexer 20 to prevent the multi-channel signal source received by the signal receiving unit 10 from entering the playback unit 30. In other embodiments, the preset lock time can be played according to the playback. The time setting. The television set 100 further includes a timer 90 that starts timing when the television set 100 is playing, and is used to time the playing time of the television set 100. The determining unit 70 is further configured to determine whether the playing time exceeds the preset playing time. And outputting the trigger signal when the playing time exceeds the preset playing time, so that the controller 60 turns off the multiplexer 20 and outputs a user interface prompting the user to input a password. For example, the playing time is set to 60 minutes, and the determining unit 70 is timing. When the timer 90 is clocked for 60 minutes, the trigger signal is output. Referring to Figure 3, an upper The control method is used to restrict the television set 100 from playing the program, and the method includes the following steps: Step 601: preset password and lock time. The user password and lock time can be set by the TV manufacturer before the TV is shipped from the factory, or 098144169 Form No. A0101 Page 7 of 15 0982075558-0 [0026] 201122891 According to the user's custom settings, the lock time is set according to the time when the TV is turned on, and can also be set according to the TV play time. For example, you can set The boot time is 22: 00~0:00 or it is the boot time. You can also set the playback time to 60 minutes. [0027] Step 603: Determine whether the boot/play time meets the preset lock time. If the TV's power on/play time matches the preset lock time, it will match the lock time. On the contrary, it does not meet the lock time. When the lock-up time is 22: 00~00: 00, the TV is turned on at any time during the time period of 22: 00~00: 00, and the preset lock-up time is met. And when turned on at other times, it does not meet the preset lock time. When the lock time is 60 minutes of play time, the TV will match the preset lock time when it is played for 60 minutes. [0028] Step 605: If the lock time is met, the user is prompted to input a password; if the lock time is not met, 613 is performed. [0029] Step 607: Determine whether the password input by the user matches the preset password, and determine whether the password input by the user is correct. Specifically, the password input by the user is compared with the preset password. When the password input by the user is the same as the preset password, it is determined that the password input by the user matches the preset password, that is, the password input by the user is correct. Conversely, when the password entered by the user is different from the preset password, it is determined that the password entered by the user does not match the preset password, that is, the password entered by the user is incorrect. [0030] Step 609: If the password input by the user does not match the preset password, it is determined whether the number of times the user inputs the wrong password exceeds a preset number of times; if the password input by the user matches the preset password, step 613 is performed. 098144169 Form No. A0101 Page 8 of 15 0982075558-0 201122891 [0031] [0033] [0033] Step 611, if the number of times the user enters the wrong password exceeds the preset number of times, the multiplexer is turned off. If the number of times the user enters the password does not exceed the preset number of times, step 605 is performed. In step 613, the program is played normally. The above television set and the control method thereof can limit the start-up or play time of the television by setting a password and the lock time, and selectively restrict the television to play the program, thereby preventing the child from affecting the vision and learning due to the long time of watching the television program. . Further, the above-described television set and its control method can prevent the user from performing an erroneous operation by mistakenly entering the password by turning off the multiplexer and inputting the password a plurality of times. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
