The embodiment of the application can be applied to various types of display devices (including but not limited to smart televisions, set top boxes and other devices), and optionally, the devices can access various pages of the display devices by using various different controllers.

In the embodiment of the application, after the display device receives the key value of the remote controller, the display device sends the key value to the UI interface design, and the UI interface is a page management system. It should be noted that, the communication interface of the display device described in this embodiment specifically receives the key value sent by the remote controller. The communication interface transmits the key value to the controller of the display device for further processing of a focus switching process to be described later.

Fig. 14 is a schematic structural diagram of a UI interface provided in the embodiment of the present application. The UI interface includes a page management module, a focus recording module, and a focus setting module, and certainly, the UI interface also includes other modules, which are not illustrated one by one here. The page management module is responsible for creating, updating, switching and destroying pages; and the focus setting module is responsible for setting focus display of the focus in the page according to the position of the focus acquired from the page.

After the UI interface obtains the key value of the remote controller, the UI interface confirms the current page needing the key value by using the page management module and sends the key value to the page.

In the embodiment of the application, the page is responsible for defining and displaying the page control. Fig. 15 shows a schematic structural diagram of a page provided in an embodiment of the present application, and referring to fig. 15, in the embodiment of the present application, a focus calculation module is included in the page, and the focus calculation module may calculate a position of a focus in the page and send the calculated position of the focus to a UI interface.

The page is also responsible for defining whether the page control can obtain focus (i.e. the attribute of the page control is a focused page control or a non-focused page control), and describes the page control identification of the next available focus of the control in the four directions of up, down, left and right (i.e. the identification value of the next page control is specified in the page control attributes nextfocusUP, nextfocusDOWN, nextfocusLEFT, nextfocusIGHT).

The page is also responsible for the processing of focus change events (focus change event refers to the page control getting focus onFocus, losing focus onBlur). And the page control for obtaining the focus is the focused page control.

With continued reference to fig. 15, the focus calculation module is responsible for receiving and converting the key value into a movement direction (direction) of the focus, and transmitting the movement direction into the focus position according to the current focus position currentFocusNode and the movement direction to calculate the position of the focus after the focus is updated.

It should be noted that the focus calculation module may be a piece of js (javascript) script program. This program needs to be embedded in the page for focus control.

Fig. 16 is a flowchart illustrating a method for focus management according to an embodiment of the present application, where as shown in fig. 3, the method includes:

step 1601: the display equipment acquires a key value sent by the remote controller, and the key value is used for controlling the moving direction of the focus.

Step 1602: analyzing the object pointed by the key value into a component object, specifically analyzing the object pointed by the key value into a reference number of the component object;

step 1603: the display equipment sends the reference number to a current page;

step 1604: the display equipment determines a second position after the focus is updated by using a unidirectional data flow mode according to a current focus value of a first position of the focus of a current page and a reference number of the component object;

Step 1605: the display equipment acquires the second position and switches the focus to the second position;

in step 1601, a key value of the remote controller corresponds to a moving direction of the focus, the correspondence is predetermined, and the display terminal can determine the moving direction corresponding to the key value through the received key value.

A user sends an operation instruction carrying a key value to a terminal by using a remote controller, the remote controller is used as operation equipment to transmit the key value to the terminal, and the terminal transmits the key value to a display page; the page has an attribute that can obtain the key value, which is specified in the protocol and is not described herein again.

In step 1602, the object pointed to by the key value is analyzed as a component object, specifically, as a reference number of the component object;

in this application, the information of the component object where the focus is located is recorded by the display device, which may specifically be a reference number of the component object, so that the display device no longer records an ID number of an object that needs to be focused.

In this embodiment, it can be considered that the display device is always set to be a component object.

The component object in focus has a reference to the component when it is created, specifically a reference number. And the reference number of the component object is unique.

Compared with the traditional mode that the focus needs to traverse the document object model tree, the focus recording mode provided by the application does not need to traverse all document object model trees when searching the component object where the focus is located, the component object is quickly positioned according to the reference number of the component object when being created, and the time for traversing the document object model tree to search the focus ID is saved to a certain extent.

The component object is uniquely present, i.e., it exists a unique number when created and stored.

Therefore, the efficiency of focus positioning can be improved by using the reference number of the component object where the focus is located to find the mode for positioning the focus.

The method of recording focus by using the component object can solve the problem of ID duplication of the nodes of the document object model tree to a certain extent.

FIG. 6 is a diagram illustrating a component object structure of a focus object repeat scene in a document object model tree.

When [ DIV: 2-2 ] the display device can be directly adjusted from [ DIV: and 2, acquiring a component object where the object is located to obtain a product index value (DIV: 2-2 ] node references of the component object in which the object resides.

It should be noted that the objects [ DIV: 2-2, when the assembly object is not the assembly object, the focus assignment process can be terminated; when the object [ DIV: and 2-2, when the component objects are the component objects, setting the component objects of the display equipment to the global system.

It can be seen that the focus is recorded and found in the manner of component objects, and the document object model tree may not need to be traversed [ body ] and [ DIV: 1, [ DIV: 1-1, [ DIV: 1-2, [ DIV: 2 ], [ DIV: 2-1, [ DIV: 2-2 ] such a way addressing finds the position [ DIV: 2-2), but directly provides the component reference number stored in the definition at the time of creation for finding and positioning, namely: [ body ] and [ Ref: 2 ], [ Ref: 2-2, [ DIV: and 2-2, the complex traversal process is simplified.

The display devices operate on objects and are all constrained to operate within the upper level component object, so that there is no possibility of duplicate focus occurring. In the component object where the object finding focus is located [ DIV: 2-2 ], the display device does not need to pay attention to [ DIV: this assembly object.

When needed, will [ DIV: 3 ] assembly object [ DIV: 2-2 ] when the assembly object is set to be in focus to be displayed on the display device, only the distance between [ DIV: and 3, operating under the assembly object, wherein the operation does not involve [ DIV: 2 ] assembly object [ DIV: 2-2 ] the assembly object comprises the following specific operation flows: [ body ] and [ Ref: 2 ], [ Ref: 2-2, [ DIV: 2-2. So that the problem of focus duplication does not occur, and finally the display device needs to display the component object [ DIV: 2-2.

It should be noted that there may not be two equal objects in a system but they represent different elements, i.e. if there are 2 objects equal, it can be considered that they necessarily represent the same element. Therefore, the focus is recorded by the component object, so that the problem of focus searching error is fundamentally avoided.

The mode of using the component object to record the focus can solve the problem that the document object model tree node is not mounted in the focus switching process to a certain extent.

FIG. 8 is a diagram illustrating a component object structure of a scene in which a focus object is not yet mounted in a document object model tree.

Although there are nodes that are not mounted, but objects have already been created, our upper nodes can get the object references of the new nodes.

When the object in focus needs to be displayed, the object is fully operational. Because it has established a unique reference number at the time of creation, although the corresponding branch is not yet mounted in the document object model tree.

The display equipment can change the state of the object, so that the object is displayed in a form expected by the display equipment when being mounted, and the problem that the focus is lost due to the fact that the focus object is not mounted in time is solved.

In step 1603, the display device sends the reference number to the current page. The attributes of the pages include the stacking order, and the page with the higher stacking order is always displayed in front of the page with the lower stacking order. In the embodiment of the application, the page which needs to be operated by the user through the remote controller is the page displayed at the forefront, so that the page with the largest stacking sequence in the pages displayed by the terminal, namely the current page, can be determined as the page where the focus is located at present.

In step 1604, the display device determines the updated second position of the focus by using a unidirectional data flow according to the current focus value of the first position of the focus of the current page and the reference number of the component object.

The focus is recorded based on the manner of the inter-component object, and the switching of the focus will be explained in detail below. To facilitate switching focus, the display device uses a unidirectional event stream to address this issue.

Fig. 9 shows a schematic diagram of a unidirectional data flow.

A unidirectional data flow refers to a state that can be modified from only one direction. When the display device needs to modify the state of the component object, it can be considered to completely restart a modified flow. This way of modification limits the state modification, making the state predictable.

The data transfer between component objects is unidirectional, i.e. data is always transferred from a parent component object to a child component object, which may have its own data maintained within it, but it has no right to modify the data transferred to it by the parent component, which is done for better decoupling between component objects.

In the display of the page, a plurality of sub-component objects may depend on certain data of the parent component object, and if the sub-component objects can modify the data of the parent component object, a change of one sub-component object may cause changes to all sub-component objects depending on the data, so the display device described in the present application uses a unidirectional data stream method to solve the switching of the focus.

In the document object modeled tree, a parent component object (which may also be considered a parent node) records the child component object of focus, which in turn records the child component objects of the child component object of focus.

Therefore, the display device can switch the focus of page display according to the recording information of the multilayer structure, and can preset an initial focus for each parent component object node, thereby further preventing focus loss.

It should be noted that, the limitation of the preset initial focus data also supports the memory function of the focus, and the display device does not need to spend time to store and read the previous focus position.

Fig. 10 is a schematic diagram showing a structure of the current page focus switching of the display device.

Switching focus within a page includes two scenarios, switching focus within sibling component objects, switching focus between component objects.

Fig. 11 shows a schematic diagram of switching the focus of the display device between sibling component objects, i.e. the component objects switched by the focus are all mounted under the same parent component object.

This scenario is the most common case, as shown in fig. 11, the focus is at the first position in the current page, i.e. the child component object with the current focus value of a1, the child component object a1 is mounted under the parent component object a, a2 is the second position where the focus needs to be switched, and a2 child component object is also mounted under the parent component object a.

In this case, the display device only needs to assign the value of the Focus of the current page to a2, and obtain the second position of the Focus.

Fig. 12 shows a schematic diagram of switching of the focus of the display device between parent component objects, i.e. the component object switched by the focus is mounted under a different parent component object.

This scenario is also very common, mainly consisting in the direct switching of multiple lists in the current page of the display device. The focus is at the first position in the current page, i.e., the child component object with the current focus value of a2, which is mounted under parent component object A at a2, B1 is the second position where the focus needs to be switched, and B1 is mounted under parent component object B.

With continued reference to fig. 12, the display device uses a current focus to record the focus under the current component object, i.e. the first position of the focus of the current page, and when the first focus moves out, the display device can be used for focus recording.

The display device directly assigns the Focus value of the current page to the parent component object B at the second position of the Focus, then the recursive search mechanism of the Focus finds the currentFocus value of the current Focus value of the parent component object B, and finally the Focus value is assigned to B1, so that the second position of the Focus is obtained.

It should be noted that the assignment of the above focuses is performed by using the reference number of the component object.

In some embodiments, the current page may specifically be a focus calculation module of the current page, and may determine a page control corresponding to the first position, and when a page control exists in the moving direction controlled by the key value, determine the page control having the attribute of the focused page control as the focused page control. The attribute is a focused page control, the presentation focus can be located in the page control, and a user can execute corresponding actions, such as clicking operation, on the page control through the focus.

If the current page determines the focused page control, the position of the focused page control may be determined as the second position after the focus is updated.

It should be noted that in the embodiment of the present application, the page control refers to some visible tags in the current page, such as a button, a text input box, and the like.

It should also be noted that, in the embodiment of the present application, detailed description is only given by taking the UI interface of the smart television as an example, the UI interface of the corresponding display device is accessed through other display devices, and the server interface and the web interface interconnected with the display device are both within the protection scope of the present application, and are not described herein again.

In some embodiments, the current page may specifically be a focus calculation module of the current page, and if it is determined that a page control corresponding to the first position exists in the moving direction controlled by the key value, and a page control with a property of being a focused page control does not exist, a page control with a property of being a focused page control is searched in a DOM (Document Object Model) of the current page, and the position of the searched page control is determined as the second position after the focus is updated.

It should be noted that a page is a collection of a series of page controls included in the page, and these page controls form the tree structure, which is generally referred to as a DOM tree.

In some embodiments, the current page may be specifically a focus calculation module of the current page, and if it is determined that a page control corresponding to the first position does not exist in the moving direction controlled by the key value, the position of a preset page control in the first page is determined as the second position after the focus is updated. The preset page control may be any page control in the first page, and is determined specifically according to an actual situation, which is not described herein again.

In step 1605, the display device acquires the second position and switches the focus to the second position;

the above process is described below by a detailed embodiment.

As shown in fig. 13, a schematic flowchart of the focus movement provided in the embodiment of the present application includes:

step 1301: and the user operates the keys of the remote controller to trigger the remote controller to send the corresponding key values to the display equipment.

Step 1302: and the display equipment calls a standard interface and sends the key value to the UI interface.

Step 1303: and the focus recording module in the UI sends the reference number of the component object corresponding to the key value to the focus calculation module of the current page.

Step 1304: and the focus calculation module of the current page calculates a second position of the focus according to the reference number and the first position of the focus in the current page, stores the second position in the current page, and sends the second position to the focus setting module in the UI.

The remote control module is used for acquiring a key value sent by the remote controller, analyzing an object pointed by the key value into a component object, judging whether the analyzed object is the component object or not, and if not, ending the assignment process; and

if the analyzed object is a component object, analyzing the current focus value of the component object, and if the current focus value is the component object, assigning the current focus value to the current component object;

if the analyzed current focus value is not the component object, if not, ending the process; and

if the current component is a component object, if the previous focus exists, the state of the previous focus is reset, and the state of the current focus is set.

The assignment logic can find that the focus logic simplifies a lot of operations, but simultaneously, the focus logic is more ergodic, safer and more efficient. The state of the focus is uniformly controlled by the display device, and the generation of multi-focus problems can be prevented. The display device adds the focus state of the component object, and each component object realizes a style in each state. Not only the centralized management of the states is realized, but also the individual requirements are met.

The hardware associated with implementing the above-described focus management in the embodiments of the present application will be explained below.

and determining the position of the focused page control as the second position after the focus is updated.

Optionally, if the page control corresponding to the first position is determined, in the moving direction controlled by the key value, a page control exists, and a page control with the attribute of being a focused page control does not exist, searching for the page control with the attribute of being the focused page control in the document object model DOM of the first page;

And determining the position of the searched page control as the second position after the focus is updated.
