Currently, in some display devices 200 with two slots (slots), a user may normally view the display device 200 when the system is operating normally through one of the slots. When The system of The display device 200 needs to perform OTA (Over The Air) upgrade, a background process of The system (for example, an android system) can erase and write an upgrade package to another idle slot through The background process based on The currently running slot, and after The erasing is completed, the erased slot has The latest target system version. After the display device 200 is turned on by direct current or alternating current, the system is automatically started from the erased slot, and the system upgrade of the display device 200 is completed.

The system upgrade mode of the dual-slot display device 200 can erase and write another idle slot during the normal operation of one slot, the system upgrade process does not affect the use of the display device 200 by a user, and the upgrade method can also be called as 'seamless upgrade'; and, if the system on the slot of the target version cannot be started, the display device 200 will automatically roll back to the system on the slot of the old version to continue to run, so that the situation that the display device 200 cannot be started due to system failure is not caused.

However, when the dual socket display device 200 is upgraded, after erasing another socket, a message is immediately sent to the user to prompt the user to immediately restart the display device 200 to use the upgraded target version system, if the user is operating the display device 200 or watching video, the user will immediately restart the display device 200 to interrupt the operation of the user, thereby affecting the user experience.

Based on the foregoing, in the embodiment of the application, a display device system upgrading method and a display device are provided, where the display device 200 is a dual-slot display device 200, and in the display device 200, each slot corresponds to a partition, the controller 250 may erase and write the first slot to erase and write the content to the first partition and erase and write the second slot to erase and write the content to the second partition in the display device 200. According to the scheme, the system upgrade package can be erased while the current version system is running, the restarting time of the display device 200 is determined according to the selection of a user, and further the system upgrade and the version switching can be completed without affecting the normal use of the display device 200 by the user, and the watching experience of the user is not affected.

The slots in the display device 200 are used for determining to insert the carried content into a specified position, so that the template is segmented, and the template has modularized characteristics and greater reusability and is equivalent to an expansion tool.

Fig. 5 illustrates a control flow diagram of the controller 250 of the display device 200 according to some embodiments.

In the embodiment of the present application, as shown in fig. 5, the display device 200 may erase and write two slots respectively, and erase and write different contents into two corresponding partitions, the controller 250 erases the contents of the current version system in one of the partitions, and controls the display device 200 to operate the current version system based on the contents in the partition, and then, when a system upgrade is required, erases a system upgrade package with new version contents into a second partition, so that the second partition has the contents of the new version system. Therefore, the scheme of the embodiment of the application can upgrade the system while the display device 200 is operating normally, and the normal use of the user is not affected in the upgrade process.

In general, after the system upgrade package is written, the display apparatus 200 needs to be restarted immediately in order to start a new version of the system, but if the user is operating the display apparatus 200 or is watching some content, such an immediate restart method necessarily affects the user's operation. Therefore, in the embodiment of the present application, as shown in fig. 5, after the second partition is erased, the controller 250 may query the user whether to restart immediately so as not to affect the normal operation of the user. If the user selects to restart the display device 200 later, the user may still continue to operate, and the controller 250 may control the display device 200 to enter the dc standby flow, so that when the display device 200 is restarted, the content of the new version system in the second partition is operated, so as to achieve the purpose of switching to the new version system.

As can be seen from the above, the scheme of the embodiment of the present application can complete system upgrade and version switching without affecting the normal use of the display device 200 by the user, so as not to affect the viewing experience of the user.

Fig. 6 illustrates a second control flow diagram of the controller 250 of the display device 200 according to some embodiments.

As in the previous embodiments, the controller 250 may query the user as to whether to restart immediately after the second partition erasure is completed so as not to affect the normal operation of the user. However, if the user is currently operating or using the display device 200, the process of querying the user may also affect some operations of the user, such as overlaying the query page before the operation page or overlaying the video content being played, etc. To avoid this, as shown in fig. 6, in some embodiments, the controller 250 may further need to detect whether the current display content of the display 260 is a main page, and if so, indicate that the user is not currently watching any video content or operating any software, at this time, the controller 250 may control the display 260 to display a restart prompt to the user; if display 260 is not currently displaying a main page, indicating that the user may be watching video content or using some application software, controller 250 does not control display 260 to display a system upgrade prompt so as not to affect the user's ongoing operation.

FIG. 7 illustrates a schematic diagram of a restart hint in accordance with some embodiments.

As shown in fig. 7, the restart prompt is used to prompt the user to restart the display device immediately or at a later time to complete the system version switch. Two choices are provided for the user in the restart prompt interface, namely an option of 'immediately restarting' and an option of 'later restarting'. The user can select according to own requirements.

And, the above-described operation of detecting the display contents is performed cyclically, and if the display 260 does not currently display the main page, it may be detected again after a certain period of time until the main page is detected. Moreover, the detection interval time may be set according to actual situations, which is not specifically limited in the embodiment of the present application.

In some embodiments, if the user selects the "immediately restart" option after viewing the restart prompt as shown in fig. 7, the controller 250 controls the display device 200 to immediately restart to start the latest version of the system in response to an immediately restart instruction, which may be considered as input. If the user selects the "restart later" option after viewing the restart prompt as shown in fig. 7, it may be considered that the user inputs a restart later instruction, and the controller 250 controls the display device 200 to perform a restart operation after the user finishes using the restart later instruction.

Fig. 8 illustrates a schematic diagram of a dc standby flow according to some embodiments.

For a later restart instruction, since the display apparatus 200 cannot be restarted immediately, the controller 250 is required to perform an additional dc standby flow to detect the state of the display apparatus 200 and thereby determine the timing of the restart of the display apparatus 200. In some embodiments, as shown in fig. 8, the main way for the controller 250 to execute the dc standby process is: in response to a later restart instruction of a user, setting an attribute value for controlling system restart in a system running program to be 1, and controlling the display device 200 to enter an STR standby flow, wherein, taking an android system as an example, a method for controlling system restart in the system running program may be sys.ota.later.reboot, and in the embodiment of the present application, the attribute value needs to be set to be 1; after the display device 200 performs the STR standby procedure, the display device 200 may run a program that specifically executes the STR standby procedure in the system running program, when the STR standby procedure goes to a certain method for determining the attribute value (for example, a gotosleep ()) in powermanager service, the controller 250 may invoke a restart interface (for example, a shutdown ()) in the power management service powermanager service, which is the system native, to restart the display device 200 when the STR standby procedure determines that the attribute value is 1, so that the display device 200 is restarted, and then the content of the target version system in the second partition is run.

In the STR (Suspend to RAM) standby process, the controller 250 of the display device 200 stores the current running state and other data in the memory, closes the devices such as the hard disk and the peripheral device, and enters the standby state. At this time, the memory still needs power to maintain its data, but the power consumption of the whole machine is very small. When the display device 200 is awakened, the controller 250 reads data from the memory, returns to the state before suspension, and resumes faster.

In general, after the user uses the display device 200, the user may operate the display device 200 to enter a state of shutdown, sleep, or sleep, but the display device 200 may be called dc standby only when the user turns on the display device 200 after entering the shutdown state. Not all states of the display device 200 are reset, and the reset effect is achieved. Therefore, in the above-described embodiment, if the user selects to restart the display apparatus 200 later, the controller 250 needs to forcedly modify the STR standby flow to the dc standby flow, so that, regardless of the state in which the user operates the display apparatus 200 after using the display apparatus 200, the controller 250 can control the display apparatus 200 to perform the dc standby flow so that the display apparatus 200 can be automatically switched to the new version system operation in the second partition when being restarted.

In some embodiments, if the user selects "immediately restart" after viewing the restart prompt interface shown in fig. 7, the controller 250 may also invoke a corresponding restart interface, such as, for example, shutdown () or the like, in response to the user's immediately restart instruction, thereby controlling the display device 200 to immediately restart. When the display device 200 is restarted, it may automatically switch to a new version of system operation within the second partition.

In addition, as described in the foregoing embodiments, the display device 200 in the embodiment of the present application has two slots, which are respectively referred to as a first slot and a second slot, and the first slot and the second slot are both stationary and need to be erased to have corresponding contents. The controller 250 may erase the first slot, further erase the content to the first partition, and erase the second slot, further erase the content to the second partition. In some embodiments, the content of the current version system that is previously written to the first slot in the first partition may be used to make the display device 200 operate normally, where the second slot is in an idle state; then, while the display device 200 normally operates the current version of system content in the first partition, the controller 250 downloads a system upgrade package corresponding to the display device 200 system from the server side; finally, the controller 250 erases the system upgrade package for the second idle slot through the already erased upgrade installation package process, i.e. the background process, in the first slot, so that the second partition has the content of the new version system.

As can be seen from the above, the display device provided in the embodiment of the present application is a display device 200 with two slots, and the controller 250 of the display device 200 can erase and write the content to the first slot and the second slot, so as to erase and write the corresponding content to the first partition and the second partition respectively. While the display device 200 normally operates the current version of system content in the first partition, erasing the system upgrade package for the second partition so that the second partition has the content of the new version of system; and, in case that the user chooses to restart the display device 200 later, the display device 200 is controlled to enter a direct current standby flow, so that when the display device 200 is restarted, the content of the new version system in the second partition is operated. Therefore, the scheme of the application can erase and write the system upgrade package while the system is running, and the restarting time of the display device 200 is determined according to the selection of the user, so that the system upgrade and version switching can be completed without affecting the normal use of the display device 200 by the user, and the viewing experience of the user is not affected.

Fig. 9 is a flowchart illustrating a method for upgrading a display device system according to some embodiments, and as shown in fig. 9, a method for upgrading a display device system provided in an embodiment of the present application may include the following steps:

In step S101, while the display device 200 is operating normally the system content of the current version in the first partition, the system upgrade package is rewritten on the second partition, so that the second partition has the content of the new version system. In this embodiment of the present application, the display device 200 may erase and write different contents to two partitions, where one partition erases and writes the contents of the current version system, and the display device 200 runs the current version system based on the contents in the partition, and then when a system upgrade is required, erases and writes a system upgrade package with new version contents to a second partition, so that the second partition has the contents of the new version system.

In step S102, in the case that the user selects to restart the display device 200 later, the display device 200 is controlled to enter the dc standby flow, so that when the display device 200 is restarted, the content of the new version system in the second partition is operated.

According to the scheme provided by the embodiment of the application, the display device 200 can be restarted at the corresponding time according to the restarting method selected by the user, and the system upgrading and the version switching are completed under the condition that the normal use of the display device 200 by the user is not influenced, so that the watching experience of the user is not influenced.

In some embodiments, the above method may further comprise: detecting the current display content of the display 260 under the condition that the content of the new version system in the second partition is completely rewritten; in the case that the display 260 displays a main page, controlling the display 260 to display a restart prompt to a user; wherein the restart prompt is used to prompt the user to restart the display device 200 immediately or at a later time to complete the system version switch. A schematic diagram of the restart hint is shown in fig. 7 above.

If the content displayed on the display 260 is a main page, indicating that the user is not currently watching any video content or operating any software, the controller 250 may control the display 260 to display a restart prompt to the user; if display 260 is not currently displaying a main page, indicating that the user may be watching video content or using some application software, controller 250 does not control display 260 to display a restart prompt so as not to affect the user's ongoing operation.

In some embodiments, the method further includes controlling the display device 200 to execute a dc standby procedure, where a specific execution procedure of the dc standby procedure is: in the case where the user selects to restart the display apparatus 200 later, an attribute value for controlling system restart in the system running program (for example, an attribute value of sys.ota.later.reboot in the android native system) is set to 1, and the display apparatus 200 is controlled to enter the STR standby flow; the running program of the STR standby procedure includes a method (e.g., sys. Ota. Later. Reboot) for determining the attribute value; and under the condition that the STR standby flow judges that the attribute value is 1 in the running process, a restarting interface (such as a shutdown ()) in a power management service PowerManagerService of a system original is called to restart the display equipment 200, so that when the display equipment 200 is started again, the content of a new version of the system in the second partition is run.

In some embodiments, the above method further comprises: erasing and writing the first slot in advance so that the first partition has the content of the current version system; downloading a system upgrade package corresponding to the system of the display equipment 200 from a server side while the display equipment 200 normally operates the system content of the current version in the first partition; the system upgrade package comprises the content of a new version system; and erasing the system upgrade package for the idle second slot by utilizing an upgrade installation package process in the first slot so that the second partition has the content of the new version system.

In some embodiments, the above method further comprises: in the event that the user selects to immediately restart the display apparatus 200, a restart interface (e.g., shutdown ()) in the system-native power management service powermanager service is invoked to restart the display apparatus 200.

As can be seen from the foregoing embodiments, the method for upgrading a display device system provided in the embodiments of the present application may be applied to the dual-slot display device 200 in the foregoing embodiments, so as to achieve the purpose of upgrading one system while the other system is operating normally, and the user may select to restart the display device 200 immediately or restart the display device 200 later according to his own needs to complete the switching of system versions. In the embodiment of the application, the system upgrading and the system upgrading prompt can not influence the normal use of the display device 200 by the user, and further, the watching experience of the user can not be influenced.
