Description

System update display method and display equipment

Technical Field

The present application relates to the field of internet technologies, and in particular, to a system update display method and a display device.

Background

In an intelligent terminal (such as an intelligent television), two ways of updating an intelligent terminal system generally exist, one is an execution way of adopting background automatic silent updating so that the system updating is completed on the principle of not disturbing the use of a user (for example, when the intelligent television adopts the background automatic silent updating system, the user can normally watch television programs on a foreground), and the other is that the user inquires whether a latest software version exists at present or not and updates the intelligent terminal system under the condition that the latest software version exists by triggering a manual detection system updating function of a 'setting' page of the intelligent terminal.

However, when the background automatic silent updating system is adopted, the entry triggering the update function of the manual detection system is often set to be in an un-triggerable state on the intelligent terminal, so as to prevent the user from repeatedly updating the system. However, this processing scheme is too simple and violent, when a background automatic silent updating system is adopted, a user is liable to be confused that an entry for manually detecting an updating function of the system cannot be triggered, and the user cannot know the updating condition of the system.

Disclosure of Invention

The application discloses a system updating display method and display equipment, which are used for preventing updating failure caused by that a user directly closes an intelligent terminal because the updating condition of a system cannot be determined.

According to a first aspect of embodiments of the present application, there is provided a display apparatus including:

a display;

a controller coupled with the display and configured to:

when an externally input instruction for detecting system update is received, inquiring whether a process for updating a second system serving as a backup of a first system is started in the currently running first system;

when the process for updating the second system is inquired to be started and is determined to be updating the second system, determining that the current system background is updating the second system through the process for updating the second system, and displaying prompt information that the current system background is updating the second system on the foreground through the display;

and if an instruction which is input from the outside and is used for switching the process of updating the second system executed in the background to the foreground for execution is received, displaying the updating progress of the second system in each updating state through the display according to each updating state of the process used for updating the second system in the updating process.

According to a second aspect of the embodiments of the present application, there is provided a system update display method, including:

when the process for updating the second system is inquired to be started and is determined to be updating the second system, determining that the current system background is updating the second system through the process for updating the second system, and displaying prompt information that the current system background is updating the second system on a foreground;

and if an instruction which is input from the outside and is used for switching the process of updating the second system executed in the background to the foreground for execution is received, displaying the updating progress of the second system in each updating state in the foreground according to each updating state of the process used for updating the second system in the updating process.

The technical scheme provided by the embodiment of the application can have the following beneficial effects:

as can be seen from the above technical solutions, in the solution provided in the present application, when an externally input instruction for detecting a system update is received (i.e. a manual detection system update function is triggered), if a process that has been started to update a second system that is a backup of a currently running first system is queried in the first system and the process is updating the second system, a prompt message that a background of the current system is updating the second system may be displayed in a foreground to prompt a user that a system update is currently being performed in the background, and further, when an externally input instruction for switching a process that is performed in the background and is executed to update the second system to a foreground is received, an update progress of the second system in each update state may be displayed in the foreground according to each update state in which the process for updating the second system is in the update process, therefore, the user can see the updating condition of the system in the foreground, and the situation that the user directly closes the intelligent terminal to cause updating failure is prevented.

For the purpose of understanding the embodiments provided in the present application, the techniques involved in the embodiments of the present application will be described below.

First, it should be noted that, in order to not affect the normal use of the device by the user when updating the system in the intelligent terminal (such as the smart television), the intelligent terminal in the related art may implement system update by using an a/B seamless architecture in the process of the normal use of the device by the user.

The A/B seamless architecture comprises an update _ engine and two independent systems, wherein the update _ engine is arranged in the intelligent terminal, and the two independent systems are respectively stored in partitions of different Slot (Slot), such as a system A stored in the partition where the Slot A is located and a system B stored in the partition where the Slot B is located. In the A/B seamless architecture, each slot position has an attribute of 'startable', the attribute is used for indicating that a system stored in the slot position is correct, a device can start from the slot position and run the system stored in the slot position, only one slot position in each device belongs to a starting state, and only one system can be run in the device at a time.

Based on the a/B seamless architecture, during the normal use of the device by the user, the update _ engine process may be executed to complete the system update (for example, the system update is completed by erasing and writing the read-only partition for the storage system according to the content in the downloaded update package). For example, assuming that the current device operates in Slot a and the running system in the device is system a, when the system in the device is updated, system B may be updated according to the downloaded update package under the condition of normally operating system a, after the system B is updated, the updated system B is marked, at this time, the device is restarted by direct current or alternating current once, and the next time the user uses the device, the system B is automatically switched to Slot B according to the mark, and the user can enjoy the updated software.

The technical solution in the embodiments of the present application is further described in detail below with reference to the accompanying drawings. Referring to fig. 2, fig. 2 is a flowchart of a method for updating a display by a system according to an embodiment of the present application. As an embodiment, the flow shown in fig. 2 may be applied to the display device as described above.

As shown in fig. 2, the process may include the following steps:

step 201, when receiving an externally input instruction for detecting system update, querying whether a process for updating a second system as a backup of a first system is started in the currently running first system.

It should be noted that, in the embodiment of the present application, the instruction for detecting system update received from the outside is generated when the user manually triggers the manual detection system update function set on the display device outside the display device.

For example, a user may use a remote controller configured for the display device to trigger a manual detection system update function through a setting interface of a key on the display device; or, if the display device has a touch screen function, the user may also trigger a manual detection system update function on the setting interface in a touch screen manner.

In specific implementation, the system update in this embodiment of the present application may be based on the above-mentioned a/B seamless architecture, that is, the first system and the second system included in this embodiment of the present application may be stored in partitions of different slot locations, where the first system refers to a system running in the current device, the second system refers to a system not running in the current device, and the system update in this embodiment of the present application refers to updating the second system not running under a condition that the first system is running normally.

Here, the second system and the first system are backup to each other, for example, when the first system has a problem in operation, the second system may be enabled to ensure that the user uses the device normally. In addition, in the embodiment of the present application, the first system and the second system may be systems of the same version or systems of different versions.

For example, in the embodiment of the present application, when the first system and the second system are different versions of systems, a function of rolling back an old version of the system may be provided for a user.

Optionally, the process for updating the second system in the embodiment of the present application may be an OTA (Over the Air) process using an OTA (Over the Air) technology. The method comprises the following 5 steps of updating the system by using an OTA process; updating package detection, updating package downloading, updating package checking, updating package installation and system restarting. In the embodiment of the application, an OTA process can be started, a regular trigger OTA process is set to realize background automatic silent updating, for example, every N seconds is set to trigger the OTA process to a server side of the system, whether a new update package for updating the equipment system exists is detected, when the update package for updating the equipment system exists in the server side, the update package is downloaded to the local equipment, the integrity, the validity and the like of the update package downloaded to the local equipment are verified, and when the verification is passed, an update _ engine process is further called to install the update package and the system is restarted to operate the updated system.

Step 202, when it is found that the process for updating the second system is started and it is determined that the process is updating the second system, it is determined that the current system background is updating the second system through the process for updating the second system, and a prompt message that the current system background is updating the second system is displayed in a foreground.

As an embodiment, when the process for updating the second system is an OTA process, if it is queried that the OTA process is started in the currently running first system, it may be determined whether the OTA process is updating the second system by querying whether a state currently stored in a state machine of the OTA process is an idle state.

Here, the state stored in the state machine of the OTA process may be used to indicate an update state in which the OTA process of the second system is currently updated. According to the above, the updating of the system by using the OTA process is divided into the following 5 steps; updating package detection, updating package downloading, updating package checking, updating package installation and system restarting. Optionally, the states stored in the state machine of the OTA process may be divided into the following states according to the 5 steps: idle, detection, finding new version, downloading completion, downloading failure, verification completion, verification failure, installation success, installation failure, waiting for restart and restart to represent different updating stages corresponding to different moments when the second system is updated.

In this embodiment of the present application, if the state currently stored in the state machine of the OTA process is not an idle state, but another state other than the idle state (for example, a state in detection or a state with medium non-idle installation) is queried, it may be determined that the current system background is updating the second system through the process for updating the second system, and this embodiment of the present application displays, in the foreground, a prompt that the current system background is updating the second system.

For example, the content of the prompt message may be referred to in fig. 3, and the prompt message may also be used to ask the user whether to switch the process of updating the second system, which is executed in the background, to the foreground. Optionally, if the user selects the "yes" button on the interface, an instruction for switching the process executed in the background to update the second system to the foreground may be generated, and if the user selects the "no" button on the interface, the interface may be directly closed.

Step 203, if an instruction for switching the process of updating the second system executed in the background to the foreground to be executed is received, displaying the updating progress of the second system in each updating state in the foreground according to each updating state of the process for updating the second system in the updating process.

As an embodiment, after the user sees the prompt information in step 202, the user may select whether to switch the process of updating the second system executed in the background to the foreground, for example, by selecting the "yes" button on the prompt information interface shown in fig. 3, inputting an instruction to switch the process of updating the second system executed in the background to the foreground, and by selecting the "no" button on the prompt information interface shown in fig. 3, the process of updating the second system continues to be executed in the background.

Further, after receiving an instruction for switching a process of updating the second system executed in a background to be executed in a foreground, when the process of updating the second system is an OTA process, an interface for indicating an update progress in the update state corresponding to the state may be displayed in the foreground according to the queried state stored in the state machine of the OTA process. For example, if the state stored in the state machine of the current OTA process is downloading, an interface as shown in fig. 4 may be displayed in the foreground, the download progress of the update package for updating the second system is displayed by using the percentage and progress bar, the progress bar and the percentage value are updated in real time according to the download progress, and when the progress bar is read full and the percentage value is 100%, a prompt message that the download is successful is popped up in the interface, or when the progress bar is not read full within a specified time and the percentage value is not 100%, a prompt message that the download is failed is popped up in the interface.

It should be noted that, in the embodiment of the present application, after the process for updating the second system is switched to the foreground for execution, the interface of the update progress displayed on the foreground is continuously updated according to the update state corresponding to the real-time process. For example, when the OTA process is switched to the foreground for execution, if the state displayed in the state machine of the OTA process is downloading, the display interface shown in fig. 4 is displayed in the foreground, after a period of time, the OTA process has completed downloading the update package of the second system, and starts to check the downloaded update package, the interface shown in fig. 5 is displayed in the foreground, and further, when the update package is installed after the check is completed, the interface shown in fig. 6 is displayed in the foreground.

Meanwhile, as can be seen from the interfaces shown in fig. 4, 5, and 6, in the embodiment of the present application, after the process for updating the second system is switched to the foreground for execution, the instruction for switching the process for updating the second system, which is executed by the foreground, to the background for execution may be further input through the "background execution" button displayed on the interfaces, at this time, the foreground will not display the update progress of the second system in each update state any more, and the interfaces for displaying the update progress of the second system will all disappear.

Thus, the flow shown in fig. 2 is completed.

As can be seen from the flow shown in fig. 2, when an instruction for detecting a system update is received from outside (i.e. a manual detection system update function is triggered), if a process that has started to update a second system that is a backup of a currently running first system is queried in the currently running first system and the process is updating the second system, a prompt message that the second system is being updated in the background of the current system may be displayed in the foreground to prompt a user that a system update is currently being performed in the background. Further, if an externally input instruction for switching the process of updating the second system executed in the background to the foreground is received, the update progress of the second system in each update state can be displayed on the foreground according to each update state of the process for updating the second system in the update process, so that a user can see the update condition of the system on the foreground, and the failure of updating caused by the fact that the user directly closes the intelligent terminal is prevented.

It should be noted that, as another embodiment, when it is queried in step 201 of the embodiment of the present application that the process for updating the second system is not started yet, or when it is found in step 202 of the embodiment of the present application that the process for updating the second system is started, but it is determined that the process does not update the second system, it may be determined that the current system background does not update the second system through the process for updating the second system, at which point the process is triggered to update the second system, and displaying the updating progress of the second system in the updating state in real time in the foreground according to the updating state of the process for updating the second system in the updating process, the interface of the update progress in the update state displayed by the foreground may refer to the interface used when the process of updating the second system is executed in the foreground.

And optionally, when the process for updating the second system is the OTA process in this embodiment, if the state currently stored in the state machine of the OTA process is queried to be the idle state, it may be determined that the process does not update the second system.
