Currently, in some display devices 200 with two slots (slots), when the system is operating normally through one of the slots, the user can view the display device 200 normally. When The system of The display device 200 needs to perform OTA (Over The Air) upgrade, a native background process of The system (for example, an android system) may perform an erasure upgrade package on another idle slot through The background process based on The currently running slot, and after erasure is completed, The erased slot has The latest target system version. After the display device 200 is powered on by dc or ac, the system is automatically started from the erased slot, and at this time, the system upgrade of the display device 200 is completed.
The system upgrade method of the dual-slot display device 200 can erase and write the idle slot during the normal operation of the slot, the system upgrade process does not affect the use of the display device 200 by the user, and the upgrade method can also be called as 'seamless upgrade'; moreover, if the system in the slot of the target version cannot be started, the display device 200 will automatically roll back to the system in the slot of the previous old version to continue to operate, which will not cause the situation that the display device 200 cannot be started due to system failure.
However, when the dual-slot display device 200 is upgraded, after erasing and writing the other slot is completed, a message is immediately sent to the user to prompt the user to restart the display device 200 immediately so as to use the upgraded target version system, and if the user is operating the display device 200 or watching a video, the user can operate the display device 200 immediately by restarting the display device 200 immediately, which interrupts the user's operation and further affects the user experience.
Based on the above, the present embodiment provides a method for upgrading a display device system and a display device, where the display device 200 is a display device 200 with dual slots, and each slot corresponds to a partition in the display device 200, and the controller 250 can erase and write the first slot to erase and write the content to the first partition in the display device 200, and erase and write the second slot to erase and write the content to the second partition. According to the scheme of the embodiment of the application, the system upgrade package can be erased and written while the current version system is running, the restarting time of the display device 200 is determined according to the selection of the user, the system upgrade and the version switching can be completed under the condition that the normal use of the display device 200 by the user is not influenced, and the watching experience of the user is not influenced.
The slot in the display device 200 is used to decide to insert the carried content into a specific position, so that the template is blocked, and the display device has the characteristics of modularization and greater reusability, and is equivalent to an extension tool.
Fig. 5 illustrates a control flow diagram for the controller 250 of the display device 200 according to some embodiments.
As shown in fig. 5, in this embodiment of the application, 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 and writes contents of a current version system into 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 needed, the system upgrade package with new version contents is erased and written into a second partition, so that the second partition has contents of the new version system. Therefore, the scheme of the embodiment of the application can upgrade the system while the display device 200 operates normally, and the normal use of a user cannot be influenced in the upgrading process.
In a general case, the display apparatus 200 needs to be restarted immediately after the system upgrade package is written in order to start the new version of the system, but if the user is operating the display apparatus 200 or watching some content, such an immediate restart method inevitably 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 ask the user whether to restart immediately in order not to affect the normal operation of the user. If the user selects to restart the display device 200 later, the user may continue to operate the display device 200, and the controller 250 may control the display device 200 to enter a dc standby flow, so that when the display device 200 is started again, the content of the new version system in the second partition is run, and the purpose of switching to the new version system is achieved.
As can be seen from the above, according to the scheme of the embodiment of the application, system upgrade and version switching can be completed without affecting the normal use of the display device 200 by the user, so that the viewing experience of the user is not affected.
Fig. 6 illustrates a second control flow diagram of the controller 250 of the display apparatus 200 according to some embodiments.
As described in the foregoing embodiment, the controller 250 may inquire of the user 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 querying the page to overlay before the operating page or over the video content being played, etc. To avoid this, as shown in fig. 6, in some embodiments, the controller 250 further needs to detect whether the currently displayed content of the display 260 is a main page, and if the currently displayed content is a main page, it indicates that the user is not currently viewing 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 the display 260 is not currently displaying the main page, indicating that the user may be watching the video content or using some application software, the controller 250 does not control the display 260 to display the system upgrade prompt so as not to affect the user's operation.
FIG. 7 illustrates a schematic diagram of restart hints according to some embodiments.
As shown in fig. 7, the restart prompt is used to prompt the user to restart the display device immediately or to restart the display device later to complete the system version switching. The user is provided with two choices in the restart prompt interface, namely an "immediate restart" option and a "later restart" option. The user can select according to the requirement of the user.
And, the above-mentioned operation of detecting the display content is performed in a loop, if the display 260 currently displays not the main page, the detection may be performed again after a period of time until the main page is detected. In addition, the detected interval time may be set according to an actual situation, and is not specifically limited in the embodiment of the present application.
In some embodiments, if the user selects the "restart immediately" option after viewing the restart prompt shown in fig. 7, that is, selects to restart the display device immediately, it may also be considered as inputting an immediate restart instruction, and the controller 250 may control the display device 200 to restart immediately in response to the immediate restart instruction to start the latest version of the system. If the user selects the option "restart later" after viewing the restart prompt as shown in fig. 7, it may be regarded that the user inputs a later restart instruction, and the controller 250 controls the display device 200 to restart after the user finishes using the display device in response to the later restart 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 immediately restarted, the controller 250 is required to perform an additional dc standby flow to detect the state of the display apparatus 200 and to determine the timing for restarting the display apparatus 200. In some embodiments, as shown in fig. 8, the main ways for the controller 250 to execute the dc standby procedure are as follows: 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, where, taking an android system as an example, a method for controlling system restart in the system running program may be sys. After the display device 200 performs the STR standby procedure, the display device 200 may run a program that is specially used for executing the STR standby procedure in its system running program, and when the STR standby procedure goes to a certain method (e.g., a gotosleep () in PowerManagerService) for determining the attribute value, the controller 250 may call a restart interface (e.g., a shutdown () in a PowerManagerService of the system native power management service to restart the display device 200 when the STR standby procedure determines that the attribute value is 1, so that when the display device 200 is restarted, the content of the target version system in the second partition is run.
In the STR (Suspend to RAM) standby flow, the controller 250 of the display device 200 stores data such as the current operating state in the memory, closes the hard disk, the peripheral device, and the like, and enters a waiting 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 woken up, the controller 250 reads data from the memory, returns to the state before suspension, and has a high recovery speed.
Generally, after using the display device 200, a user may operate the display device 200 to enter a power-off state, a hibernation state, or a sleep state, but the display device 200 can be called as a dc standby state only by turning on the display device 200 after entering the power-off state, in this standby mode, the power supply of the power-off display device 200 is turned off, but the auxiliary power supply is still turned on, and when the display device 200 is restarted again, the display device 200 may be switched to a new version system of the second partition to operate. The display device 200 may not be restarted after entering all states. Therefore, in the above-described embodiment, if the user selects to restart the display apparatus 200 later, the controller 250 needs to forcibly modify the STR standby flow to the dc standby flow, so that the controller 250 can control the display apparatus 200 to perform the dc standby flow no matter what state the user operates the display apparatus 200 after using up the display apparatus 200, so that the display apparatus 200 can be automatically switched to the new version system operation in the second partition when being started again.
In some embodiments, if the user selects "restart immediately" after viewing the restart prompting interface shown in fig. 7, the controller 250 may further call a corresponding restart interface, such as shutdown () or the like, in response to the user's immediate restart instruction, so as to control the display apparatus 200 to restart immediately. When the display device 200 is restarted, the system operation can be automatically switched to the new version in 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 static and need to be erased to have corresponding contents. The controller 250 can erase and write the first slot to erase and write the content to the first partition, erase and write the second slot to erase and write the content to the second partition. In some embodiments, the content of the current version system in the first partition may be erased and written to the first slot in advance, so that the display device 200 operates normally, and the second slot is in an idle state; then, while the display device 200 normally operates the current version 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 idle second slot through the 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 200 provided in the embodiment of the present application is a display device 200 with dual slots, and the controller 250 of the display device 200 can erase and write contents in the first slot and the second slot, and further erase and write corresponding contents in the first partition and the second partition, respectively. While the display device 200 normally operates the current version system content in the first partition, erasing and writing the system upgrade package for the second partition so that the second partition has the content of the new version system; and, in case that the user selects to restart the display apparatus 200 later, the display apparatus 200 is controlled to enter a dc standby flow, so that the content of the new version system in the second partition is run when the display apparatus 200 is restarted. Therefore, the scheme of the application can erase and write the system upgrade package while the system is running, and the restart opportunity of the display device 200 is determined according to the selection of the user, so that 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 viewing experience of the user cannot be affected.
