In the embodiment of the application, through a parental control function of the display device, a user can select target objects to set parental locks one by one, such as applications, signal source channels, live television channels, television program contents and the like, so that the user without the operation right can be prevented from being unable to operate the target objects.
However, after the user sets the target object, each target object has an independent parental lock, so that the situation that the parental user needs to repeatedly input unlocking information during the process of using the display device easily occurs, the operation is complicated, and the user experience is not friendly.
For example, in a single use process before the user powers on and powers off the display device, when the user exits from a locked application and enters the locked application again, the user needs to input the unlocking information again, and when the user exits from a locked application and selects to enter another locked application in an application center, the user also needs to input the unlocking information again, or when the user exits from a locked application and switches a signal source channel of the display device from a current HDMI1 channel to an HDMI4 channel provided with a hometown lock, the user also needs to input the unlocking information again, so that the user experience is not friendly.
In order to solve the problem, the embodiment of the application provides a method for controlling parental locks of display equipment, which can implement unified control on a plurality of objects provided with parental locks, and for a user with an operation right item, in the process of using the display equipment once, the user is prevented from repeatedly inputting unlocking information, so that the user operation is reduced, and the experience is improved.
In the embodiment of the present application, a plurality of objects of different types are involved in the display device, for example, an application installed on the display device, a plurality of signal source channels (such as HDMI1, HDMI2, HDMI3, HDMI4, AV and/or TV, etc.) of the display device, live television channels (such as channel 1, channel 2, etc.) corresponding to different live broadcast signals that can be received by the display device, and television program content that can be played by the display device.
The user can optionally set the homeman lock on the part of the objects, and when a certain object is set with the homeman lock, the user who cannot provide unlocking information cannot operate the object.
Since various operations can be performed on an object, for example, when a certain object is an application program, multiple operations such as starting, exiting, setting, etc. can be performed on the object, in order to more clearly describe the technical solution of the present application, the present application proposes a concept of presetting an operation instruction.
The preset operation instruction is used to instruct the target object to execute the processing action corresponding to the preset operation instruction, and specifically, according to the difference of the target object, the preset operation instruction and the processing action corresponding to the preset operation instruction may include:
a first instruction, configured to instruct to start a target application of an application center of a display device, where the target application is the target object, and a processing action corresponding to the first instruction is to start the target application;
a second instruction, configured to instruct to receive and play a program signal of a target signal source channel, where the target signal source channel is the target object, and a processing action corresponding to the second instruction is to receive and play the program signal of the target signal source channel;
a third instruction for instructing to receive and play the program signal of the target live television channel;
and a fourth instruction for instructing to play the target television program content.
Fig. 7 and 10 are flowcharts of a display device parental lock control method according to an exemplary embodiment of the present application, respectively, where fig. 7 is a flowchart of a method when a preset operation instruction is a first instruction and a target object is an application. As shown in fig. 7, the method may include:
step 701, receiving a first instruction, where the first instruction is used to instruct to start a target application of a display device application center.
Fig. 8 is a diagram illustrating an interaction scenario of a user using a remote control and a display device according to an exemplary embodiment of the present application, where as shown in fig. 8, a screen of the display device presents an application center interface and a selector, UI icons of a plurality of applications are displayed in the application center, the selector is used for indicating a currently selected application, and when a target application is selected, the user presses an OK key on the remote control, and the remote control sends a first instruction corresponding to a key value of the OK key to the display device.
In this embodiment, the UI layer of the display device system receives the first instruction and executes the corresponding processing logic.
Step 702, determine whether the target application has a parental lock, if yes, execute step 703, if no, execute step 708.
Step 703, acquiring the parent lock state of the target application.
For an object provided with a parental lock, for example, an application program in this embodiment, as well as a signal source channel, a live television channel, television program content, and the like in another embodiment, the parental lock may be in two states in different situations, one of which is a locked state, and at this time, the object may only be operated when unlocking information is input and verification passes, and the other of which is an unlocked state, that is, when unlocking information is input and verification passes, and at this time, the object may be operated.
The parent lock state is used as a judgment basis for judging whether the user needs to be prompted to input unlocking information to start the application or not by the UI layer. If the application is judged to be in the locking state according to the parent lock state, the application can be started only if the user inputs correct unlocking information, otherwise, the application can be operated without inputting the unlocking information.
In a specific implementation, the parent lock state of the application may be saved as an attribute of the application, and when the object needs to be locked, the state of its parent lock is set to UNLOCK, and when the object does not need to be locked, the state of its parent lock is set to true.
Step 704, determining the parent lock status of the target application, if the parent lock status is the locked status, then step 705 is executed, if the parent lock status is the unlocked status, then step 708 is executed.
Step 705, generating an interface prompt for prompting a user to input unlocking information, and presenting the interface prompt on a screen of the display device.
Fig. 9 is an exemplary illustration of a possible interface prompt for prompting a user to input unlocking information, in which an input box for inputting an unlocking password and a number option constituting the password are displayed, and the user selects and inputs a number by controlling a mobile selector through a remote controller.
And step 706, receiving unlocking information input by a user according to the displayed interface prompt. As described in step 105, the unlocking information is generally an unlocking password, but in another embodiment, the unlocking information may also be gesture information or voice information.
Step 707, the unlocking information is verified, if the verification is passed, step 708 is executed, and if the verification is not passed, step 705 is executed.
At step 708, the target application is launched.
And executing step 709 while executing step 708, judging whether a unified unlocking instruction is received, if so, executing step 710, and if not, not acting.
In step 710, the parental lock status of each object provided with the parental lock is modified to an unlocked status.
The objects provided with the parental lock comprise application programs, signal source channels, live television channels and television program contents. For the application program with the parental lock, the UI layer modifies the parental lock state, and for the signal source channel, the live television channel and the television program content with the parental lock, the target middleware for directly controlling the display device chip to play signals modifies the parental lock state.
The unified unlocking instruction is used for instructing the display device to modify the parental lock state of each object provided with the parental lock into an unlocking state during the use, and further, in the process of using the method, if the objects need to be operated, the unlocking information does not need to be input again, for example, after step 108, if exiting from the target application and re-entering the target application, the application can be launched directly without re-entering the unlock information, as another example, if exiting from the target application 2 and selecting the entry application 4 at the application center, there is no need to enter the unlocking information again, or, for example, if exiting from the target application 2 and switching the signal source channel of the display device from the current HDMI1 channel to the HDMI4 channel provided with the home lock, unlocking information does not need to be input again, so that user operation is greatly simplified, and user experience is improved.
It should be noted that the "use process of this time" may be understood as a period of time from when the display device is turned on to before the display device is turned off, specifically, after the display device is turned on, the use of the display device by the user starts, and after the display device is turned off, the use is finished.
The unified unlocking instruction is input by a user through a function control provided by the UI interface. For example, referring to fig. 9, in fig. 9, the function control for a user to input an instruction by checking is further included, and when the user checks "remember the unlock state before shutdown", a unified unlock instruction is input to the display device.
In step 711, it is detected whether a shutdown command is received, if so, step 712 is executed, and if not, no action is taken.
In step 712, the parental lock status of each of the objects provided with the parental lock is modified to a locked status, and shutdown is performed.
As can be seen from the foregoing embodiments, in the embodiments of the present application, when a first instruction for instructing to start a target application of a display device application center is received, a parent lock state of the target application is first determined, if the target application is in a locked state, a user is prompted to input unlocking information and a unified unlocking instruction, the target application is started when the unlocking information is verified, and the parent lock state of each object provided with a parental lock is modified into the unlocked state when the unified unlocking instruction is received, so that the user does not need to repeatedly input unlocking information during the use of the display device, thereby reducing user operations and improving user experience.
FIG. 10 is a flowchart illustrating a method when the predetermined operation command is the second command and the target object is the signal source channel. The target middleware is used for controlling the switching of the signal source channel and controlling whether the display equipment receives and plays the program signal. As shown in fig. 10, the method may include:
in step 101, the UI layer receives a second instruction, where the second instruction is used to instruct to switch a signal source channel of the display device to a target signal source channel, so as to receive and play a program signal of the target signal source channel.
Fig. 11 is another interaction scenario of a user using a remote controller and a display device according to an exemplary embodiment of the present application, where as shown in fig. 11, a screen of the display device presents a signal source channel selection interface and a selector, a UI icon of a plurality of signal source channels is displayed in the interface, the selector is used to indicate a currently selected signal source channel, and in a case that a target signal source channel is selected, the user presses an OK key on the remote controller, and the remote controller sends a second instruction corresponding to a key value of the OK key to the display device.
Step 102, the UI layer sends a second instruction to the target middleware.
And 103, switching the signal source channel from the current channel to the target signal source channel by the target middleware.
And 104, the target middleware judges whether the switched target signal source channel is provided with a home lock, if so, the step 105 is executed, and if not, the step 111 is executed.
And 105, the target middleware acquires the parent lock state of the switched target signal source channel.
Step 106, the target middleware determines the parental lock state of the target signal source channel, if the target signal source channel is in the lock state, step 107 is executed, and if the target signal source channel is in the unlock state, step 111 is executed.
Step 107, the target middleware generates an instruction for instructing the UI layer to acquire the unlocking information, and sends the instruction to the UI layer.
And step 108, the UI layer receives the instruction, generates an interface prompt for prompting a user to input unlocking information, and presents the interface prompt on a display device screen.
And step 109, the UI layer receives unlocking information input by a user and sends the unlocking information to the target middleware.
And step 110, the target middleware verifies the unlocking information, if the unlocking information passes the verification, step 111 is executed, and if the unlocking information does not pass the verification, step 107 is executed.
And step 111, the target middleware controls the display equipment chip to receive and play the program signal of the target signal source channel.
And in step 112, the target middleware judges whether a unified unlocking instruction is received, if so, the step 113 is executed, and if not, the action is not carried out.
In step 113, the parent-lock status of each object having a parent lock set therein is modified to an unlocked status by the UI layer and/or the target middleware.
For the application class object, the UI layer sets the parental lock state of the application class object to be the unlocking state, and for the channel class or the object of the television program content, the target middleware sets the parental lock state of the application class object to be the unlocking state.
This embodiment still includes: and detecting whether a shutdown instruction is received, if so, modifying the parental lock state of each object provided with the parental lock into a locking state, and executing shutdown. If not, no action is taken.
As can be seen from the foregoing embodiments, in the embodiments of the present application, when a first instruction for instructing switching of a signal source channel of a display device is received, the display device is first switched to a target signal source channel, and then a parental lock state of the target signal source channel is obtained, if the target signal source channel is in a locked state, a user is prompted to input unlocking information and a unified unlocking instruction, and under the condition that the unlocking information is verified, a program signal of the target signal source channel is received and played, and under the condition that the unified unlocking instruction is received, a parental lock state of each object provided with a parental lock is modified to an unlocking state, and further, in the use process of the display device by the user, the user does not need to repeatedly input unlocking information, so that user operations are reduced, and user experience is improved.
In order to further ensure that the content of the display device can be safely browsed by underage, a time lock can be set by using a home control function, and for the locked time slot object, a user without operation authority cannot operate any object on the display device.
Based on this, on the basis of the above embodiment, in another embodiment, the parent lock control method for a display device provided by the present application further includes the steps shown in fig. 12:
in step 121, an arbitrary operation instruction is received, where the arbitrary operation instruction includes the preset operation instruction and a non-preset operation instruction.
In step 122, it is determined whether the time for receiving the operation command belongs to a lock time period, if so, step 123 is executed, and if not, step 125 is executed.
In step 123, unlock information is acquired.
For a specific implementation process of obtaining the unlocking information, reference may be made to the above embodiments, which are not described herein again.
In step 124, the unlocking information is verified. If the verification is passed, step 125 is performed, and if the verification is not passed, step 123 is performed.
