In specific implementation, the application packages in the application layer are not limited to the above examples, and may actually include other application packages, which is not limited in this embodiment of the present application.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information about an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

In some embodiments, the activity manager is to: managing the life cycle of each application program and the general navigation backspacing function, such as controlling the exit of the application program (including switching the user interface currently displayed in the display window to the system desktop), opening, backing (including switching the user interface currently displayed in the display window to the previous user interface of the user interface currently displayed), and the like.

In some embodiments, the window manager is configured to manage all window programs, such as obtaining a size of the display screen, determining whether a status bar exists, locking the screen, clipping the screen, controlling a change of the display window (e.g., zooming the display window out, dithering the display, distorting the display, etc.), and the like.

In some embodiments, the system runtime layer provides support for the upper layer, i.e., the framework layer, and when the framework layer is used, the android operating system runs the C/C + + library included in the system runtime layer to implement the functions to be implemented by the framework layer.

In some embodiments, the kernel layer is a layer between hardware and software. As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display driver, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (such as fingerprint sensor, temperature sensor, touch sensor, pressure sensor etc.) etc..

In some embodiments, the kernel layer further comprises a power driver module for power management.

In some embodiments, software programs and/or modules corresponding to the software architecture of fig. 4 are stored in the first memory or the second memory shown in fig. 2 or 3.

In some embodiments, taking the magic mirror application (photographing application) as an example, when the remote control receiving device receives a remote control input operation, a corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the input operation into an original input event (including information such as a value of the input operation, a timestamp of the input operation, etc.). The raw input events are stored at the kernel layer. The application program framework layer obtains an original input event from the kernel layer, identifies a control corresponding to the input event according to the current position of the focus and uses the input operation as a confirmation operation, the control corresponding to the confirmation operation is a control of a magic mirror application icon, the magic mirror application calls an interface of the application framework layer to start the magic mirror application, and then the kernel layer is called to start a camera driver, so that a static image or a video is captured through the camera.

In some embodiments, for a display device with a touch function, taking a split screen operation as an example, the display device receives an input operation (such as a split screen operation) that a user acts on a display screen, and the kernel layer may generate a corresponding input event according to the input operation and report the event to the application framework layer. The window mode (such as multi-window mode) corresponding to the input operation, the position and size of the window and the like are set by an activity manager of the application framework layer. And the window management of the application program framework layer draws a window according to the setting of the activity manager, then sends the drawn window data to the display driver of the kernel layer, and the display driver displays the corresponding application interface in different display areas of the display screen.

In some embodiments, as shown in fig. 5, the application layer containing at least one application may display a corresponding icon control in the display, such as: the system comprises a live television application icon control, a video on demand application icon control, a media center application icon control, an application center icon control, a game application icon control and the like.

In some embodiments, the live television application may provide live television via different signal sources. For example, a live television application may provide television signals using input from cable television, radio broadcasts, satellite services, or other types of live television services. And, the live television application may display video of the live television signal on the display device 200.

In some embodiments, a video-on-demand application may provide video from different storage sources. Unlike live television applications, video on demand provides a video display from some storage source. For example, the video on demand may come from a server side of cloud storage, from a local hard disk storage containing stored video programs.

In some embodiments, the media center application may provide various applications for multimedia content playback. For example, a media center, which may be other than live television or video on demand, may provide services that a user may access to various images or audio through a media center application.

In some embodiments, an application center may provide storage for various applications. The application may be a game, an application, or some other application associated with a computer system or other device that may be run on the smart television. The application center may obtain these applications from different sources, store them in local storage, and then be operable on the display device 200.

The user can select the corresponding program on the display device according to own preference. Often some programs are not suitable for viewing by a particular user, for example, some violent programs are not suitable for viewing by children. In order to facilitate control of programs that are not suitable for viewing by a particular user, a parental lock feature is added to some display devices. The user can lock some channels by using the parental lock function of the display device, so as to achieve the purpose of limiting some users from watching programs played on the locked channels. The process of locking some programs by using the parental lock function of the display device is specifically as follows: a user calls a channel lock list on an interface of a parent lock, and the channel lock list comprises locking and unlocking controls corresponding to all channels; then, the user finds out an unlocking control corresponding to the channel needing to be locked in the channel lock list; and the user realizes the locking of the channel corresponding to the locking and unlocking control by clicking the locking and unlocking control. In the channel lock list, the arrangement sequence of the locking and unlocking controls is arranged according to the sequence of the channel numbers, and the sequence is fixed and cannot be changed under the influence of other factors. In markets such as europe and north america, the number of channels provided by a provider is very large, often reaching thousands, and it is extremely difficult to find a locking/unlocking control corresponding to a locked channel and unlock the locked channel in such a huge number of channels.

In order to solve the above technical problem, a first aspect of embodiments of the present application provides a display device, where the display device at least includes: a display and a controller. The interaction flow diagram of the display device and the user can be seen in fig. 6;

the controller is configured to execute step S101 to call a first unlock list;

in the application, a first locking list comprises locking and unlocking controls corresponding to all channels; each locking and unlocking control corresponds to one channel; the locking and unlocking controls in the first locking list are sorted according to the channel numbers of the corresponding channels; each channel corresponds to a weight value, the weight values are stored in a memory inside the controller, and the weight value corresponding to each locking and unlocking control in the initial state is equal to the initial weight value;

in one possible embodiment, the display device may receive M channels, which are: channel 1, channel 2, channel 3 \8230 \ 8230, channel M. The corresponding first unlocking list comprises M locking and unlocking controls, wherein the M locking and unlocking controls are respectively control 1, control 2 and control 3 \8230 \8230andcontrol M. Wherein, control 1 corresponds to channel 1, control 2 corresponds to channel 2, control 3 corresponds to channel 3 \8230: \ 8230, and control M corresponds to channel M. In the first list, the locking and unlocking controls are sorted according to the channel numbers of the corresponding channels, and fig. 7 is a schematic diagram of the first unlocking list according to a possible embodiment, and it can be seen that the locking and unlocking controls are arranged according to the channel numbers of the corresponding channels in an ascending order.

This embodiment is not limited to M; in the practical application, M is determined by the number of channels that can be received by the display device.

In some possible embodiments, the initial state may be a state in which the display device first constructs the first locking list. In some feasible embodiments, the initial state may be a state in which the user releases the second locking list (which will be described in detail later), and in some feasible embodiments, the initial state may also be a state in which the user starts to reproduce the channel.

The initial weight value may be set according to the actual situation of the display device.

For example: in a feasible embodiment, the display device is provided with an android system, wherein the android system defaults to arrange indexes of the list in an ascending order according to the size of a number, and in order to ensure that a locking and unlocking control corresponding to a channel with a large weight value is positioned in front of a first locking list, an initial weight value can be set to be a large value; for example, in a feasible embodiment, it can be seen that the initial weight value is set to 100, and then the controller can take the (100-weight value) as the sorted index of the corresponding lock/unlock control. For example: in a feasible embodiment, the display device may directly use the ascending order of the weight values corresponding to the channel numbers, in which case the initial weight value may be set to 0.

The present embodiment is only exemplary to describe several initial weight values; in the practical application process, the initial weight value can be set according to the requirement, and the applicant does not make excessive limitation.

The embodiment of the present application does not limit the time for building the first locking list.

For example, in one possible embodiment, the controller actively constructs the first locking list each time the display device completes the channel search function. In an actual application process, after the display device completes a channel searching function, the number of channels that the display device can receive and/or the type of channels may change, in this case, if the first locking list constructed before the display device is continuously used is obviously inaccurate, therefore, each time the display device completes the channel searching function, the controller actively constructs the first locking list to ensure that the locking and unlocking controls contained in the first locking list are matched with the channels that the display device can receive.

For example: in one possible embodiment, the controller actively constructs the first locking list after the display device releases the channel lock. In the process of practical application, the user can lock a plurality of channels by using the first locking list. When a user needs to unlock all locked channels, the user can unlock one channel by one channel; however, this procedure undoubtedly consumes a lot of time for the user, and in order to enhance the experience of the user, some display devices are provided with a channel lock release function. The first locked list is released in response to a user activating a channel lock release function. After the channel lock is released by the display device, the controller actively constructs the first locking list to ensure that the first locking list can be directly called when the user uses the channel lock function next time, so that the waiting time of the user is reduced, and the experience of the user is improved.

The embodiment is only an exemplary description of several construction times of the first locking list, and the construction times of the first locking list in the actual application process may be, but is not limited to, the above several ways.

First locking list construction process referring to fig. 8, fig. 8 is a flow chart illustrating a first locking list construction process according to a possible embodiment; the construction of the first locking list is performed by a controller, and the specific controller is configured to execute steps S11 to S16.

S11, acquiring a channel list;

the channel list is used for recording all channels which can be received by the display device and the channel number of the channel. In the channel list, the channels are arranged in ascending order according to the channel numbers, and fig. 9 is a schematic diagram of the channel list according to one possible embodiment, and it can be seen from the diagram that the channels in the channel list are arranged in ascending order according to the corresponding channel numbers.

The channel list preselection is stored in a memory of the controller, and the controller generates a channel list each time a channel search function is performed by the display device. In an actual application process, after the display device completes the channel searching function, the number of channels and/or the types of channels that the display device can receive may change, in which case if the channel list before the display device is continuously used is obviously inaccurate, and therefore, the controller actively constructs the channel list each time the display device completes the channel searching function, so as to ensure the accuracy of the channel list.

S12 reads a channel number (also referred to as a first channel number in this embodiment) of a first channel in the channel list;

for example, taking the channel list shown in fig. 9 as an example, the channel number of the first channel (channel 1) is 1.

S13, constructing a locking and unlocking control corresponding to the first channel;

the controller constructs a locking and unlocking control (locking and unlocking control 1) corresponding to the channel 1; the construction method of the locking and unlocking control can adopt a control construction method which is customary in the field, and the applicant does not make much limitation here.

S14 reads a channel number of a next channel (next channel number) in the channel list;

the next channel number is the last channel number +1, for example, if the last channel number is 1, then the next channel number is 1+1=2;

s15, judging whether the next channel number is empty or not;

the implementation of determining whether the next channel number is empty may determine whether the next channel number is empty by determining whether the next channel number is recorded in the channel list.

Taking the channel list shown in fig. 9 as an example, if the next channel number is M, the channel number is not empty. If the next channel number is M +1, then the channel number is empty.

If the next channel number is not empty, executing step S15 to construct a locking and unlocking control corresponding to the next channel; proceed to step S13

The construction process of the locking and unlocking control can adopt a control construction method which is customary in the field, and the applicant does not make much limitation here.

If the next channel number is empty, step S16 is performed to generate a first locking list.

This completes the construction of the first locking list.

The implementation mode of calling the first unlocking list is various;

for example: and the user triggers the controller to call the first unlocking list by touching the corresponding control. By way of example: fig. 10 is a diagram illustrating a change of a display presentation display interface during a first unlock list invocation process according to a possible embodiment. The user can start the parental lock function, at this time, the display interface of the display can refer to the interface 11, and the display displays the parental lock control; in response to the touch of the user on the parent-parent lock control, the display displays the child control of the parent-parent lock, and at this time, the display interface of the display may refer to the interface 12. Wherein, the child control can include: channel lock controls, level lock controls, etc. In response to the touch of the user on the channel lock control, the controller invokes the first unlock list and controls the display to display the first unlock list, and the display interface of the display may refer to the interface 13.

In some feasible embodiments, the display device may be provided with voice assistant software, and the user may trigger the controller to invoke the first unlock list through a voice instruction.

The embodiment merely describes several implementation manners of invoking the first unlocking list by way of example; in the process of actual application, the implementation manner of invoking the first unlock list may be, but is not limited to, the above-mentioned several manners.

The display executes step S102 to display a first locking list; the first locking list comprises locking and unlocking controls corresponding to all channels;

the display mode of the first locking list is various;

for example: in a possible embodiment, the first locked list may be presented on the display in a full screen modality. Fig. 11 is a schematic diagram of a display presentation interface according to some feasible embodiments, wherein the interface 21 is a presentation interface of the display when the first locked list is presented on the display in a full screen mode.

For another example, in one possible embodiment, the first locking list may be presented on the display in a partial screen modality. Interface 22 of FIG. 11 is a presentation interface for a display when a first locked list is presented on the display in a partial screen mode.

For another example: in a possible embodiment, the first locking list may be presented on the display in a floating window modality. Interface 23 of fig. 11 is a presentation interface of a display when a first locked list may be presented on the display in a floating-layer window modality.

The user executes step S103 to touch the locking/unlocking control;

various touch control locking and unlocking controls can be realized;

for example: some display devices are touch screen display devices, and when the display displays the first locking list, a user can click the display at a position corresponding to the locking and unlocking control to lock or unlock a channel.

For another example, when the display presents the first locked list, the display simultaneously presents a focus, the focus configured to be controlled moved; the user can control the movement of the focus by using the remote controller, and when the focus moves to the position corresponding to the locking and unlocking control, the user can lock or unlock the channel by clicking the preset key of the remote controller. The preset key may be set according to actual requirements, for example, in some feasible embodiments, the preset key may be a confirmation key of a remote controller.

In order to facilitate the user in distinguishing which channels have been locked and which have been unlocked, in a feasible embodiment, some identification may be added to the locking and unlocking control. Specifically, referring to fig. 12, fig. 12 is a schematic diagram of a display showing a first locking list showing that channels 1 and 6 are locked according to a possible embodiment.

The controller executes the step S104 to update the weight values of the locking and unlocking controls according to the operated times of each locking and unlocking control and/or the states of the channels corresponding to the locking and unlocking controls;

various ways of updating the weight values of the locking and unlocking controls are available;

for example, in some feasible embodiments, the controller may update the weight value of the locking and unlocking control according to the state of the channel corresponding to the locking and unlocking control;

specifically, the controller is further configured to: and responding to the locking operation of the user on the locking and unlocking control, and increasing the weight value of the channel corresponding to the locking and unlocking control by N units. In practical applications, the units may be configured according to requirements, for example, the units may be 1 in some feasible embodiments, and the units may be 0.1 in some feasible embodiments.

In a feasible embodiment, each time the locking operation of the locking and unlocking control is responded by the user, the controller increases the weight value of the channel corresponding to the locking and unlocking control by N units. For example, in a possible embodiment, where N is 50, the controller adds 50 to the weight value of channel 1 in response to a user locking operation on the lock/unlock control 1.

In a feasible embodiment, the controller may record the operation of the user on each locking and unlocking control, and then increase the weight value of the channel corresponding to the locked locking and unlocking control by N units at preset time intervals. The preset time may be set according to the requirement, for example, the preset time may be 5min in a feasible embodiment. For example, in a feasible embodiment, the N units are 50, and in the period of 0min to 5min, the locking and unlocking control 1, the locking and unlocking control 2, and the locking and unlocking control 3 are locked; and 5min later, the control sound controller adds 50 to the weight value of the channel 1, 50 to the weight value of the channel 2 and 50 to the weight value of the channel 3. And in the period of 5-10 min, the locking and unlocking control 8, the locking and unlocking control 9 and the locking and unlocking control 10 are locked, and when the time is 5min, the control response controller adds 50 to the weight value of the channel 8, 50 to the weight value of the channel 9 and 50 to the weight value of the channel 10.

In a feasible embodiment, the controller may record the operation of the user on each locking and unlocking control, and when the user triggers the function of refreshing the list, the controller increases the weight value of the channel corresponding to the locked locking and unlocking control by N units. For example, the locking and unlocking control 1, the locking and unlocking control 2 and the locking and unlocking control 3 are locked; and 8min later, the user triggers a function of refreshing the list, and the controller adds 50 to the weight value of the channel 1, 50 to the weight value of the channel 2 and 50 to the weight value of the channel 3.

The controller is further configured to: and in response to the unlocking operation of the user on the locking and unlocking control, reducing the weight value of the locking and unlocking control by N units.

In a feasible embodiment, each time the user unlocks the locking and unlocking control, the controller reduces the weight value of the channel corresponding to the locking and unlocking control by N units.

In a feasible embodiment, the controller may record the operation of the user on each locking and unlocking control, and then decrease the weight value of the channel corresponding to the unlocked locking and unlocking control by N units at preset intervals.

In a feasible embodiment, the controller may record the operation of the user on each locking and unlocking control, and when the user triggers the function of refreshing the list, the controller reduces the weight value of the channel corresponding to the locked and unlocked control by N units.

In the practical application process, the controller can record the operation of the user on each locking and unlocking control, when the user triggers the function of refreshing the list, the controller increases the weight value of the channel corresponding to the locked locking and unlocking control by N units, and the controller decreases the weight value of the channel corresponding to the unlocked locking and unlocking control by N units.

In the process of practical application, the controller can record the operation of a user on each locking and unlocking control, when the user triggers the function of refreshing the list, the controller increases N units for the weight value of the channel corresponding to the locked locking and unlocking control, and the controller decreases N units for the weight value of the channel corresponding to the unlocked locking and unlocking control.

For another example: in some feasible embodiments, the weight value of each locking and unlocking control is updated according to the number of times that each locking and unlocking control is operated.

In a possible embodiment, the controller is further configured to: and responding to the locking operation of the user on the locking and unlocking control, and increasing the weight value of the channel corresponding to the locking and unlocking control by 1 unit. For example, in one possible embodiment, in response to a user locking operation on the locking/unlocking control 1, the controller adds 1 to the weight value of channel 1.

In a possible embodiment, the controller is further configured to: and responding to the unlocking operation of the user on the locking and unlocking control, and increasing the weight value of the channel corresponding to the locking and unlocking control by 1 unit. For example, in one possible embodiment, in response to the user unlocking the lock/unlock control 1, the controller adds 1 to the weight value of the channel 1.

In order to reduce the data processing amount of the controller, in a feasible embodiment, in response to the locking and unlocking control completing a set of locking and unlocking actions, the controller increases the weight value of the locking and unlocking control by 1 unit. For example, in a feasible embodiment, in response to an unlocking operation of a user on the locking and unlocking control 1, the state of the locking and unlocking control 1 is controlled and recorded as a locking state; in response to an unlocking operation of the locking and unlocking control 1 by a user, the controller adds 1 to the weight value of the channel 1. In order to reduce the data storage capacity of the controller, in a possible embodiment, each time the controller completes the action of adding 1 to the weight value of the channel 1, the controller releases the state of the locking/unlocking control 1.

In a feasible embodiment, the controller may record the operation of the user on each locking and unlocking control, count the number C of times that the locking and unlocking control completes the locking and unlocking actions (including one locking action and one unlocking action) at preset time intervals, and then add C units to the weight value of the channel corresponding to the locking and unlocking control.

In a feasible embodiment, the controller may record the operation of the user on each locking and unlocking control, and when the user triggers the function of refreshing the list, the controller counts the number of times C that the locking and unlocking control completes the locking and unlocking actions (including one locking action and one unlocking action), and then increases C units for the weight value of the channel corresponding to the locking and unlocking control.

For another example: in some feasible embodiments, the weight values of the locking and unlocking controls are updated according to the number of times that each locking and unlocking control is operated and the state of the channel corresponding to the locking and unlocking control.

For the implementation manner of updating the weight value of the add-unlock control according to the number of times that each add-unlock control is operated and the state of the channel corresponding to the add-unlock control, reference may be made to the above embodiment, which is not described herein again.

Since the weight value corresponding to each channel needs to be stored in the memory of the controller, the larger the weight value is, the larger the storage space occupied by the corresponding weight value is, and in order to reduce the occupancy rate of the storage space to a certain extent, the embodiment of the present application shows a method for calculating the weight value, specifically, refer to fig. 13, where the controller is configured to execute steps S21 to S231/S232.

Completing a group of locking and unlocking actions, and executing a step S21 by the controller to call the weight value of the channel corresponding to the locking and unlocking control;

the controller is configured to perform step S22 to determine whether the weight value is equal to a preset weight value.

The implementation manner of judging whether the weight value is equal to the preset weight value may adopt a judgment manner commonly used in the art, and the applicant does not make much limitation here. In the practical application process, the preset weight value can be configured according to the requirement, and the applicant does not make excessive limitation.

If the weight value is not equal to the preset weight value, the controller is configured to perform step S231 of controlling the weight value to be increased by 1 unit.

If the weight value is equal to the preset weight value, the controller is configured to perform the step S232 with the weight value unchanged.

For example, in a feasible embodiment, the preset weight value is equal to 49, the weight value of the channel 1 stored in the memory is equal to 49, and the weight value of the channel 2 is equal to 1; when the locking and unlocking control 1 completes a group of locking and unlocking actions, the controller calls the weight value of the channel 1 to be 49 (equal to the preset weight value), and the controller does not adjust the weight value of the channel 1; when the locking and unlocking control 2 completes a group of locking and unlocking actions, the controller calls the weight value of the channel 2 to be 1 (smaller than the preset weight value), and the controller adds 1 to the weight value of the channel 2.

And unlocking the locked channel in the channel lock list. The probability of this scenario is very high, and when a user unlocks a channel, only the locked channel is concerned, and the unlocked channel is not concerned. Therefore, it is necessary to increase the priority of the locked channels and to preferentially display the locked channels to increase the efficiency of unlocking by the user.

In the scheme shown in the embodiment of the application, the preset weight value is smaller than N units, and the N units are weight values added by the locking and unlocking control when the locking and unlocking control completes locking actions.

The preset weight value and the numerical value corresponding to N units are not limited in this embodiment, and the present invention can be applied to the solution as long as the limitation condition that the preset weight value is smaller than N units is satisfied.

In a feasible embodiment, the preset weight value may be equal to 49, n units may be equal to 50. Since scenario 1 (the number of times the lock/unlock control completes a set of lock/unlock operations) can obtain a maximum weight value of 49, the weight value of the locked channel is higher than those frequently operated but unlocked channels, so that the channel lock list is preferentially displayed. When the scene is processed, the weighted value before the channel is locked is less than 50, so that the weighted value is directly changed without judging.

The embodiment of the application shows that the technical scheme needs to store the weight value in the memory of the controller.

The way in which the weight value is stored is considered next. In the present solution, it is considered that the user does not perform frequent locking operation on a specific channel in a short time, and therefore, it is necessary to continuously record the locking operation of the user to calculate an accurate operation frequency. Therefore, the weight value cannot be saved in a normal variable, which cannot guarantee that the weight value continues to be memorized after the television is restarted, and a nonvolatile storage must be used to save the weight value. Meanwhile, the weight values to be stored are strongly correlated with the channels, that is, each channel has an independent position to store the weight value thereof. If the common EEPROM is used for storage, a variable must be created for each channel to meet the requirement;

further, in some embodiments to reduce a waste of system resources. The other scheme is that the weight value is stored in a mask _ bit at the bottom layer of a scheme provider, each channel has the mask _ bit, so that resource waste cannot be caused by storage, but strong dependence is generated on the data structure of the scheme provider, the whole function is failed due to replacement of the scheme provider, each bit in the mask _ bit is of a Boolean type, the number of bits using the mask _ bit is increased along with increase of the weight value, and the control is difficult.

Further, in some embodiments, the scheme adopted is to store the weight value into a TV database TV db (which may be referred to as a TV database in this application), and use an idle field in the database to store the channel weight value, so that system resources are not wasted, and an int-type field in TV db may be used to store data, so that an available upper limit is greatly increased. The superiority and inferiority of the above-described 3 types of nonvolatile storage are summarized as follows:

name (R)	Data type	Channel correlation	Solution quotient dependency
				EEPROM	int	Is low in	Is low in
mask _ bit flag bit	boolean	Height of	Height of
				Db (for this scheme)	int	Height of	Is low with

In response to the list refreshing instruction, the controller executes step S105 to draw a second locking list according to the updated weight value;

in some feasible embodiments, the list refresh instruction may be issued by a user, for example, some display devices are touch screen display devices, and the user may issue the refresh instruction by touching the list refresh control; for example, a user may control the focus to move through a remote controller, and when the focus moves to a list refresh control, a refresh command is issued; for example, the user issues a list refresh command using a remote control or voice.

The present embodiment only describes several ways of generating the list refresh command by way of example, and in the process of practical application, the ways of generating the list refresh command may be, but are not limited to, the above several ways.

An implementation manner of rendering the second locking list according to the updated weight value may be referred to fig. 14, where fig. 14 is a flow chart illustrating the rendering of the second locking list according to a feasible embodiment, and the controller is configured to execute steps S31 to S361/S362.

S31, calling the weight values corresponding to all channels, and arranging the weight values in a descending order.

S32 reads the maximum weight value.

S33, constructing a locking and unlocking control of the channel corresponding to the maximum weight value;

S34, reading a next weight value;

s35, judging whether the channel number corresponding to the next weight value is empty or not;

the implementation manner of determining whether the channel number corresponding to the next weight value is empty may determine whether the next channel number is empty by determining whether the next channel number is recorded in the channel list.

If the channel number corresponding to the next weight value is not empty, executing step S361 to construct a locking and unlocking control of the channel corresponding to the next weight value; continuing to execute step S34;

the construction process of the locking and unlocking control can adopt a control construction method which is conventional in the field, and the applicant does not make excessive limitation.

If the channel number corresponding to the next weight value is not empty, step S361 is executed to generate a second locking list.

In some application scenarios, the weight value corresponding to the channel may not be changed, and in this application scenario, if the table is refreshed, the redrawing of the second locking list will undoubtedly increase the data throughput of the controller. In order to reduce the data processing amount of the control to a certain extent, the present embodiment shows a page refresh method, specifically referring to fig. 15, fig. 15 is a flowchart illustrating a page refresh method according to a possible embodiment, wherein the controller is configured to execute steps S41 to S431/S432.

In response to the list refresh instruction, the controller S41 reads the weight values of all channels;

s42, judging that the weight value changes;

the implementation manner for judging whether the weight value changes may be a judgment manner commonly used in the art. In a feasible embodiment, whether the weight value changes can be determined by determining whether a new weight value is written in a preset time period. In a possible embodiment, it may be determined whether the weight value is changed by determining whether the weight value stored in the accessor is consistent with the weight value recorded in the original channel list (in some cases, the first locking and unlocking list, and in some cases, the second locking and unlocking list).

If any one of the weight values recorded in the memory is changed within the preset time period, S431 redraws the second locking list according to the updated weight;

in this embodiment, the preset time period may be a time period from the time when the first lock/unlock list construction is completed to the time when the refresh command is received; the preset time period may be a time period from a time when the refresh command is received last time to a time when the refresh command is received this time.

The second locking list may be constructed in the manner described in the above embodiments, and details are not repeated herein.

Controlling the display to display the redrawn second locked list;

or, if none of the weight values recorded in the memory has changed within the preset time period, S432 does not redraw the second locking list.

The controller executes step S106 to control the display to display the second locking list.

In response to the list refresh command, the controller will uniformly clear the previously changed weight values, adjust the channel order, and present the adjusted list to the user.

Optionally, the control is further configured to: in response to the user activating the release function (either the release of the parental lock or the release of the channel lock), the second locked list is deleted and the updated weight value recorded in the memory is changed to the initial weight value.

Under the condition that the user starts the release function, the channel which can be received by the display device is not changed, correspondingly, the data recorded in the first locking list is still available, and under the condition, the controller deletes the second locking list and changes the updated weight value recorded in the memory into the initial weight value.

Optionally, the control is further configured to: and in response to the channel re-receiving operation of the user, deleting the weight values, the first locking and unlocking list and the second locking list of all the locking and unlocking controls.

Under the condition that a user starts a channel receiving function, channels which can be received by the display device are changed, correspondingly, data recorded in the first locking list are unavailable, and under the condition, the controller deletes the weight values of all the locking and unlocking controls, the first locking and unlocking list and the second locking list.

The display device shown in the embodiment of the application comprises a display and a controller, wherein the controller can update the weight value of the channel corresponding to the locking and unlocking control according to the number of times each locking and unlocking control is operated and/or the state of the channel corresponding to the locking and unlocking control; when a user needs to perform locking and unlocking operations on some channels, the user can send a list refreshing instruction, and a second locking list is drawn according to the updated weight value in response to the list refreshing instruction; and the second locking list sorts the locking and unlocking controls based on the weight values, and the locking and unlocking controls corresponding to the channels concerned by the user are positioned at the front position. Therefore, a user of the display device shown in the embodiment of the application can quickly find the locking and unlocking control corresponding to the concerned channel in the second locking list, and the user experience is good.

In a specific implementation, the present invention further provides a computer storage medium, where the computer storage medium may store a program, and the program may include some or all of the steps in each embodiment of the method for customizing a control key and the method for starting the control key provided by the present invention when executed.
