In one example, to enable the display device to perform UI upgrade during the whole machine upgrade, a UI version upgrade package may be added to the whole machine upgrade package. In order to avoid that the newly downloaded UI version upgrade package cannot be accessed by a browser due to the fact that the UI version upgrade package in the newly downloaded complete machine upgrade package and the current version package of the UI are located in root directories of different authorities, and further the UI cannot be version-upgraded according to the newly downloaded UI version upgrade package, in one embodiment, the application requires that the browser based on the UI support access to the newly downloaded UI version upgrade package under the condition that the newly downloaded UI version upgrade package and the current version package of the UI are located in root directories of different authorities. Here, the browser may be a browser that supports only Single-page Application (SPA) such as Cobalt, and the UI may be implemented based on an HTML web page.

In one example, where the newly downloaded UI version upgrade package and the current version package of the UI are located in different-authority root directories, having the UI-based browser support access to the newly downloaded UI version upgrade package may include:

first, the browser that makes the UI based supports access to UI version packages under different root directories. The UI version package herein is a general description of the newly downloaded UI version upgrade package and the current version package of the UI, and both the newly downloaded UI version upgrade package and the current version package of the UI belong to the UI version package.

For convenience of description, a root directory in which a current version package of a UI is located is hereinafter referred to as a first root directory, and a root directory for storing a newly downloaded UI version upgrade package is referred to as a second root directory.

In order for a UI-based browser to support access to UI version packages located under different root directories, as one embodiment, a directory list may be created that includes at least a first root directory and a second root directory, and the browser may access UI version packages under either directory in the directory list when accessing the UI version packages.

To facilitate an understanding of the above list of directories, a simple example is given below.

Taking the first root directory as "/opt/bin/content/data/web/html/UI" and the second root directory as "/APPS/UI" as an example, a directory list including the first root directory and the second root directory can be created as follows:

“/opt/bin/content/data/web/html/UI

/APPS/UI”

based on the root directory list, the browser based on the UI can access the UI version package under the "/opt/bin/content/data/web/html/UI" or the UI version package under the "/APPS/UI" when accessing the UI version package.

Thus, the browser based on the UI is enabled to support to access the UI version packages under different root directories.

Second, the browser upon which the UI is based is enabled to support access to a second root directory.

As one example, the scope of access of the browser to the local file may be limited by setting an access restriction list. Specifically, at least one directory may be added to the access restriction list, and the browser may be restricted to access only the directory in the access restriction list, i.e. only have access rights to the directory in the access restriction list, thereby restricting the scope of access of the browser to local files.

Based on this, in order for the UI-based browser to support access to the second root directory, the second root directory may be added to the access restriction list of the browser.

To facilitate an understanding of the foregoing, a simple example is set forth below.

Taking the second root directory as "/APPS/UI" as an example, assume that the current access restriction list of the browser is:

“/opt/bin/content/data/web/html/UI

/var/local

/tmp”

the browser currently only has access rights to three directories in the access restriction list, and if the browser accesses the second root directory "/APPS/UI" outside the access restriction list at this time, it cannot access the second root directory "/APPS/UI" because it does not have access rights to "/APPS/UI". After adding the second root directory "/APPS/UI" to the access restriction list of the browser, a new access restriction list is available:

“/opt/bin/content/data/web/html/UI

/var/local

/tmp

/APPS/UI”

based on this access restriction list, the browser can access the second root directory "/APPS/UI" in the access restriction list.

Thus, it is achieved that the browser on which the UI is based supports access to the second root directory.

In some embodiments, the list of directories and the access restriction list may be the same list, that is, the browser may access any directory in the list, and may access the UI version package located under any directory in the list.

Through the embodiment, the browser based on the UI supports accessing the UI version program package under different root directories and supports accessing the second root directory, so that the browser can still realize the access to the newly downloaded UI version upgrade program package under the condition that the newly downloaded UI version upgrade program package and the current version program package of the UI are positioned in the root directories with different authorities.

On the basis, in the embodiment, an upgrading method of the user interface in the display device is provided to achieve version upgrading of the user interface UI of the display device. Fig. 2A-2F illustrate a flow chart of a method of upgrading a user interface in a display device. For the method shown in fig. 2A, the method may include the following steps S41-S42:

step S41: displaying a complete machine upgrading prompt when detecting that a new complete machine upgrading packet exists; the whole machine upgrade prompt is used for prompting whether a new whole machine upgrade package is needed to be upgraded or not when the new whole machine upgrade package is downloaded currently.

In one example, the whole machine upgrade prompt event in this step S41 is added as a new internal event in the browser. For ease of understanding the present embodiment, reference may be made to the following description of the browser-based UI display architecture in conjunction with fig. 2B, which is not repeated herein.

Based on the UI display architecture shown in fig. 2B, as an embodiment, after adding the whole machine upgrade prompt event to the browser as a new internal event, the UI page listens for the whole machine upgrade prompt event. And when the UI page detects a complete machine upgrading prompt event, displaying a complete machine upgrading prompt on a display of the display device. As an embodiment, the triggering of the whole machine upgrade prompt event may include: when the browser receives the information which is sent by the APM and used for indicating that the new complete machine upgrading package exists, a complete machine upgrading prompt event is triggered. As another example, the triggering of the whole machine upgrade prompt event herein may include: when the UI process receives information which is sent by the APM and used for indicating that a new complete machine upgrading packet exists, the complete machine upgrading prompt event is triggered.

When a complete machine upgrade prompt event is detected, in one example, displaying the complete machine upgrade prompt may include: and superposing a complete machine upgrading prompt on the current display picture of the display equipment. As an example, the screen currently displayed by the display device herein may include a play screen, a UI page such as a menu option page, or the like.

A schematic diagram of a screen currently displayed by the display device is exemplarily shown in fig. 2C. As shown in fig. 2C, the display device may provide a display with a play screen 61, which may be at least one of image, text, video content. For example, the playing frame shown in fig. 2C is a picture frame.

When the complete machine upgrade prompt event is detected, the current display screen of the display device is as shown in fig. 2C, and displaying the complete machine upgrade prompt includes: the complete machine upgrade prompt is displayed superimposed on the play screen 61 shown in fig. 2C. Fig. 2D illustrates a schematic diagram showing a complete machine upgrade prompt, and as shown in fig. 2D, when a complete machine upgrade prompt event is detected, a complete machine upgrade prompt 62 may be displayed superimposed on the play screen 61.

As an embodiment, the whole machine upgrade prompt may include: prompting a new complete machine upgrade package and prompting whether the display equipment needs to be upgraded. For example, the complete machine upgrade prompt may be: "is a new television upgrade package available, is an upgrade made? ". In one embodiment, the complete machine upgrade prompt may further include a selectable item indicating that an upgrade is to be performed, and a selectable item indicating that no upgrade is to be performed; in another embodiment, the complete machine upgrade prompt may include a selectable item indicating an immediate upgrade, and a selectable item indicating an upgrade while waiting for a restart without immediate upgrade. Referring to the complete machine upgrade prompt 62 shown in fig. 2D, wherein the selectable item "confirm" indicates an immediate upgrade, and the selectable item "cancel" indicates an upgrade that is not immediate upgrade while waiting for the display device to be restarted.

Step S42: and responding to an upgrade instruction based on the complete machine upgrade prompt, and installing a new complete machine upgrade package upgrade display device.

In one embodiment, the upgrade instruction based on the complete machine upgrade prompt may include: the selectable items indicating upgrade included in the whole machine upgrade prompt are selected. Namely, when the selectable items which are contained in the whole machine upgrading prompt and indicate upgrading are detected to be selected, the upgrade instruction based on the whole machine upgrading prompt is determined to be received. Taking the complete machine upgrade prompt 62 shown in fig. 2D as an example, if it is detected that the selectable item "confirm" indicating upgrade included in the complete machine upgrade prompt 62 is selected, it is determined that an upgrade instruction based on the complete machine upgrade prompt 62 is received. As one embodiment, when it is detected that the selectable item indicating not to be upgraded included in the whole machine upgrade prompt is selected, it is determined that a not to be upgraded instruction based on the whole machine upgrade prompt is received. Taking the complete machine upgrade prompt 62 shown in fig. 2D as an example, if it is detected that the selectable item "cancel" indicating not to upgrade, which is included in the complete machine upgrade prompt 62, is selected, it is determined that a not-upgrade instruction based on the complete machine upgrade prompt 62 is received.

In one example, when it is determined that an upgrade instruction based on the above-described complete machine upgrade prompt is received, a new complete machine upgrade package detected in step S41 is installed according to the upgrade instruction to upgrade the display device. In one embodiment, the complete machine upgrade package includes a UI version upgrade package. The display equipment responds to the upgrade instruction to install the whole machine upgrade package.

Specifically, the whole machine upgrade package can be downloaded according to the current OTA technology downloading flow.

When the complete machine upgrade package is downloaded, as an embodiment, the UI version upgrade package in the complete machine upgrade package may be stored to the second root directory. The second root directory here is a root directory for storing UI version upgrade packages, and the browser of the display device supports access to the UI version packages under the root directory and has access rights to the second root directory, as described above. As an embodiment, the second root directory may be preset in the display device before performing step S41, for storing the downloaded UI version upgrade package. As an embodiment, based on the UI display architecture shown in fig. 2B, a new type of message may be added in the interaction between the APM and other components in the architecture, to indicate that the complete machine upgrade package has been downloaded, and the new message may be denoted as ota_ready. When receiving the OTA_READY sent by the APM, as an embodiment, the browser triggers a complete machine upgrade prompt event to enable the UI page to display a complete machine upgrade prompt.

In response to the upgrade instruction based on the complete machine upgrade prompt, in one embodiment, if the upgrade instruction indicates to upgrade the display device immediately, the UI page notifies the browser to upgrade the UI version, and the browser upgrades the UI version according to the downloaded UI version upgrade package in response to the notification. Specifically, the UI page may notify the browser to upgrade the UI version through an extension function, where the extension function is a JavaScript extension function. With the embodiment, the UI version upgrade can be realized without restarting the display device. In this embodiment, other contents, such as upgrade packages of other functions of the display device, except for the UI version upgrade package, in the complete machine upgrade package may be upgraded according to a general complete machine upgrade procedure of the display device. As one embodiment, in response to a restart instruction for the display device, the display device is upgraded by other contents than the UI version upgrade package in the whole machine upgrade program.

In another embodiment, if the received upgrade instruction indicates to upgrade the display device immediately, the display device performs a restart on the display device and upgrades the display device according to the complete machine upgrade package in response to the upgrade instruction. As one embodiment, the process of upgrading the UI version according to the UI version upgrade package in the complete machine upgrade package may include: the operating system of the display device notifies the browser to perform UI version upgrades when the display device performs a restart. Specifically, the operating system notifies the browser to upgrade the version of the UI before the restart is performed on the display device or after the display device is completely restarted.

In one embodiment, the display device is not upgraded in response to a non-upgrade instruction based on the complete machine upgrade prompt described above. In another embodiment, in response to a non-upgrade instruction based on the complete machine upgrade prompt, the non-upgrade instruction indicates that the display device is not immediately upgraded and is to be upgraded when being restarted, after receiving a restart instruction for the display device input through the control device, the display device is restarted in response to the restart instruction, and the display device is upgraded according to the complete machine upgrade package.

In the above embodiment of the step S42, various implementations of upgrading the UI version according to the downloaded UI version upgrading package are provided, and are described below by way of example and not repeated herein.

In one embodiment, the version upgrade prompt is hidden in response to a UI upgrade instruction based on the version upgrade prompt.

The changes in the UI before and after the display device upgrade are briefly described below in connection with fig. 2E-2F:

fig. 2E illustrates a schematic diagram of UI600 prior to a display device upgrade. In one embodiment, the display device may display a menu option page 63 containing a background map and a plurality of selectable items on the display in response to an instruction to display a menu, as shown in FIG. 2E. In another embodiment, the display device displays a menu options page 63 on the display after startup, before providing a play screen to the display.

Fig. 2F illustrates a schematic diagram of UI700 after a display device upgrade. After the complete machine upgrade in which the display device includes the UI version upgrade is implemented through steps S41-S42 described above, in one embodiment, the display device displays a menu option page 71 including a background view and a plurality of selectable items on the display in response to an instruction to display a menu, as shown in fig. 2F. In practice, menu option page 71 may be distinguished from menu option page 63 in terms of background map and number of selectable items, roles, icon size, icon shape, etc., and may provide a different use experience than menu option page 63.

Thus, the description of the flow shown in fig. 2A is completed.

Through the flow shown in fig. 2A, when the display device detects that a new complete machine upgrade package has been downloaded, the display device displays a complete machine upgrade prompt, and installs the complete machine upgrade package to upgrade the display device in response to an upgrade instruction based on the complete machine upgrade prompt. The whole machine upgrading package comprises the UI version upgrading program package, so that when the display equipment performs whole machine upgrading, the UI version upgrading of the display equipment is realized, and after the whole machine upgrading is finished, the display equipment displays a new version UI.

Moreover, through the flow shown in fig. 2A, the display device can display the complete machine upgrade prompt under the condition that a playing picture is currently provided, so that a user can select whether to interrupt the current playing picture for upgrading, rather than directly interrupt the current playing picture for upgrading, thereby further improving the user experience. In one embodiment, the browser in the flow shown in FIG. 2A may be a browser that supports only single page applications, such as Cobalt.

Fig. 2B illustrates a schematic diagram of a browser-based UI display architecture. As one example, the browser herein may be a coblt browser.

As shown in fig. 2B, the UI display architecture may include: UI Pages 51, cobalt Lib (Cobalt browser library file) 52, TV Process 53, UI Process 54, and DB Framework (Driver Based Framework, drive-based system Framework) 55.

In the UI display architecture described above, the following description mainly refers to the components of the embodiments provided in the present application:

the UI page 51 is a UI page displayed on the display of the display device through the Coblat browser. In one embodiment, the UI page may access the extended functionality 522 of the Coblat browser. Specifically, the UI page may access the extended functionality 522 of the Coblat browser through an extended JavaScript interface.

The Cobalt browser library file 52, in one embodiment, may include two parts, cobalt Engines 521 and Extensions 522. The coblt engine 521 is used for realizing functions of the coblt browser, such as parsing and rendering functions of the accessed web page; extension function 522, in one embodiment, may include a local function, which is a special function associated with the display device, such as channel switching, and other functions; other functions may be functions such as accessing a local profile. In one embodiment, the functionality of the browser may be extended through a Web IDL interface.

The UI process 53, in one embodiment, is primarily used to display the UI page 51 on a display using the coblt browser library file 52. For example, the UI process 53 may adjust the UI page 51 displayed on the display with the coblt browser library file 52 according to the received information such as key input information, startup and shutdown information, etc., sent by the APM 543.

The TV process 54 mainly describes APM (application manager) 543 included therein. In some embodiments, the APM may interact with each component in the UI display architecture shown in fig. 2B, thereby managing each component. For example, after determining that the new complete machine upgrade package has been downloaded, the APM may send information indicating "the new complete machine upgrade package has been downloaded" to the UI process, and the UI process may perform a corresponding operation in response to the information, such as displaying a complete machine upgrade prompt on a display using the Cobalt browser library file 52.

In addition to the components of the UI display architecture described above, other components of the architecture shown in fig. 2B are not emphasized in this embodiment, and therefore are not described in detail herein, but are only briefly described herein:

in some embodiments, DB Framework 541, driver Based Framework, is a drive-based system Framework; MW (Middle Ware) 542, see description of Middle Ware in the related description of FIGS. 1C-1D above; directFB 55 is a graphics library that provides hardware graphics acceleration, input device processing, and abstraction.

So far, the description of the browser-based UI display architecture is completed in connection with fig. 2B. It should be noted that the browser-based UI display architecture shown in fig. 2B is merely an example, and is not particularly limited, and many similar UI display architectures may exist in practical applications.

In the following step S42, when the display device is upgraded according to the complete machine upgrade package, how to upgrade the version of the UI according to the UI version upgrade package is described:

in one example, the browser may determine, according to the value of the specified environment variable, a root directory in which the UI version package according to which the UI is updated is located, thereby accessing the UI version package under the root directory, and further updating the UI version according to the UI version package. On the basis, the browser can access the UI version upgrading program package under the second root directory according to the second root directory by setting the value of the appointed environment variable as the root directory where the downloaded UI version upgrading program package is located, namely the second root directory.

As one embodiment, the specified environment variable is an environment variable in the operating system of the display device, and is used for informing the browser of which UI version package under the directory is accessed.

As an embodiment, after the complete machine upgrade package is downloaded, and the UI version upgrade package is stored in the second root directory described above, the value of the specified environment variable is set to the second root directory. Specifically, before storing the UI version upgrade package in the second root directory, the setting the value of the specified environment variable is the root directory where the current version package of the UI is located, that is, the first root directory described above, so the setting the environment value includes: changing the value of the environment variable from the first root directory to the second root directory.

To facilitate understanding of the present embodiment, a simple example is as follows:

and recording the environment variable as UI_HOME, taking the first root directory of the UI of the display device as "/opt/bin/content/data/web/html/UI" and the second root directory as an example, after storing the downloaded UI version upgrade package into the second root directory, changing the value of the UI_HOME from the current "/opt/bin/content/data/web/html/UI" to "/APPS/UI" so as to inform the browser to access the UI version package under "/APPS/UI".

So far, the browser finishes the description of the version of the upgrade UI according to the UI version program package in the downloaded complete machine upgrade package according to the value of the appointed environment variable.

In another example, the browser may determine the directory carried by the received directory indication information as a root directory in which the UI version package according to which the UI upgrade is performed is located, thereby accessing the UI version package under the root directory, and further upgrading the version of the UI according to the UI version package. On the basis, the browser can access the downloaded UI version upgrading program package under the second root directory according to the second root directory by sending directory indication information carrying the second root directory to the browser.

In one embodiment, the directory indication information may be sent by the APM, and specifically, the APM may send the directory indication information carrying the second root directory to the browser after determining that the downloading of the complete machine upgrade package is completed and the UI version upgrade package has been stored in the second root directory. The directory indication information is used for indicating the browser to access the UI version program package according to the directory carried by the directory indication information.

As described in the above embodiment, by changing the value of the environment variable or sending the directory indication information to the browser, the UI version is updated according to the UI version-up package in the downloaded complete machine upgrade package.

It should be noted that the above embodiment is only an example of implementing step S42, and is not particularly limited. The above embodiments may also be used in combination in a specific implementation. Other ways of implementing step S42, which are easily conceivable based on the above embodiments, should be regarded as the protection of the present application.

In some embodiments, it may be necessary to switch the upgraded UI version back to the pre-upgraded UI version, i.e., to require UI version rollback, due to detection that there is a problem with the upgraded new version UI, etc. Reference is made to the method of upgrading a UI version described above. As one embodiment, in response to an instruction indicating the UI version rollback, the UI is displayed according to the instruction and in accordance with the UI version package before the upgrade, and the rollback of the UI version is implemented.

For one embodiment, displaying the UI in accordance with the pre-upgrade UI version package may include: changing the value of the appointed environment variable from the current second root directory to the first root directory, and accessing the UI version program package before upgrading under the first root directory by the browser according to the current value of the appointed environment variable to display the UI according to the UI version program package before upgrading, namely realizing UI version rollback.

As another example, displaying the UI in accordance with the pre-upgrade UI version package may include: and sending directory indication information carrying the first root directory to the browser, and accessing the UI version program package before upgrading under the first root directory by the browser according to the directory indication information to display the UI according to the UI version program package, thereby realizing UI version rollback.
