Referring to fig. 4, in some embodiments, the system is divided into four layers, which are, from top to bottom, an Application (Applications) layer (referred to as an "Application layer"), an Application Framework (Application Framework) layer (referred to as a "Framework layer"), an Android runtime (Android runtime) layer and a system library layer (referred to as a "system runtime library layer"), and a kernel layer.

In some embodiments, at least one application program runs in the application program layer, and the application programs may be windows (windows) programs carried by an operating system, system setting programs, clock programs or the like; or may be an application developed by a third party developer. In particular implementations, the application packages in the application layer are not limited to the above examples.

The framework layer provides an Application Programming Interface (API) and a programming framework for the application program. The application framework layer includes a number of predefined functions. The application framework layer acts as a processing center that decides to let the applications in the application layer act. The application program can access the resources in the system and obtain the services of the system in execution through the API interface.

As shown in fig. 4, in the embodiment of the present application, the application framework layer includes a manager (Managers), a Content Provider (Content Provider), and the like, where the manager includes at least one of the following modules: an Activity Manager (Activity Manager) is used for interacting with all activities running in the system; the Location Manager (Location Manager) is used for providing the system service or application with the access of the system Location service; a Package Manager (Package Manager) for retrieving various information related to an application Package currently installed on the device; a Notification Manager (Notification Manager) for controlling display and clearing of Notification messages; a Window Manager (Window Manager) is used to manage the icons, windows, toolbars, wallpapers, and desktop components on a user interface.

As shown in fig. 4, the core layer includes at least one of the following drivers: audio drive, display driver, bluetooth drive, camera drive, WIFI drive, USB drive, HDMI drive, sensor drive (like fingerprint sensor, temperature sensor, pressure sensor etc.) and power drive etc..

A user may view videos through display device 200 that may include digital television programs and non-digital television programs that may be data content provided for third party applications. In the process of watching videos, users often find that the current time difference displayed on the display equipment is large when different videos are played, and the use experience of the users is reduced. Illustratively, when the current time displayed when the video a is played on the display device is 8:00, the video B is switched to be played, when the video B is played on the display device, the current time displayed is 10:00, and the difference between the current time displayed when the video a and the current time displayed when the video B is played is large. Therefore, it is an urgent problem to be solved by those skilled in the art how to resolve the confusion of users due to the large difference between the current time displayed by different videos played on the display device.

When the display device plays the video, the user can control the current time displayed on the floating layer of the user interface through the control device. Illustratively, as shown in fig. 5, fig. 5 illustrates a schematic view of a user interface according to some embodiments, when the display device is playing a video, when a user can press a key on the control device to control the current time displayed on a floating layer of the user interface, as shown in fig. 6, and fig. 6 illustrates another schematic view of a user interface according to some embodiments, in which the current time is 8:00 as shown in fig. 6.

It should be noted that the present application is not limited to the manner of displaying the current time on the user interface, and in an example, the current time may be displayed on a floating layer of the user interface and located in the upper right corner of the user interface. In some embodiments, the floating layer may be configured as a transparent floating layer, which may reduce the influence on the user viewing the video when displaying the current time. In another example, a jump may be made from a user interface playing a video to another user interface, on which the current time is displayed.

The reason why the difference between the current time displayed when the video a and the video B are played is large is that: when the user watches a non-digital television program, the time displayed on the display device is determined based on the time zone information selected by the user on the display device and the utc time obtained from the server. When the user watches the digital television program, the time displayed on the display device is determined based on the time zone information in the digital television program code stream and the utc time. The determination mode of the display time is different when the digital television program and the non-digital television program are played. Generally, in a single time zone country, when a non-digital television program and a digital television program in the local time zone are played, the time displayed on the display device is the same. However, in a multi-time-zone country, the display device may receive and play digital tv programs in different time zones in the country, which may cause that the current time displayed by the current display device is determined by time zone information and utc time in the digital tv program code stream corresponding to other time zones, so that when the playing is switched between the digital tv program corresponding to other time zones and the non-digital tv program, the current time displayed by the display device may have a larger difference.

In order to solve the problem that a user cannot distinguish a specific source of currently displayed time, an embodiment of the present application provides a time zone information display method, where when a signal source of a display device is a DTV channel and a code stream exists in the DTV channel, a display state of a set time zone control is set to be different from a display state of a set parameter control on the same first user interface, so as to prompt the user that the currently displayed time of the display device is determined by content in a digital television program code stream, so that the user knows the source of the currently displayed time of the display device.

FIG. 7, as shown in FIG. 7, illustrates a flow chart of a time zone information display method according to some embodiments. The method comprises the following steps:

s100, when a first instruction for displaying a first user interface is received, a signal source of display equipment is detected, wherein the first user interface comprises a time zone setting control and a parameter setting control. In some embodiments, the signal source may be an ATV video channel (receiving analog signals), a DTV channel (receiving digital signals), an IPTV network channel, an HDMI channel, and the like, and the display device may play videos from various sources. In the embodiment of the application, before the display device displays the first user interface, the source of the currently played video is determined by detecting the signal source, and then how to display the time zone setting control in the first user interface is determined.

In some embodiments, the first instruction to display the first user interface may be accomplished by: and a second user interface is displayed on the display equipment, and a date and time setting control is displayed on the second user interface. Illustratively, as shown in FIG. 8, FIG. 8 illustrates a schematic view of a second user interface according to some embodiments, on the second user interface in fig. 8, a date and time setting control 801, a network setting control 802, a sound setting control 803, and a system upgrade control 804 are displayed, the user can move the focus to the set date and time control 801 by the control means, and pressing a confirmation key on the control device, at this time, the user interface jumps to the first user interface, as shown in fig. 9, fig. 9 illustrates a first user interface diagram according to some embodiments, the first user interface is displayed with an automatic date and time display control 901, a date setting control 902, a time setting control 903, a time zone setting control 904 and a 24h control using control 905, and the rest controls except the time zone setting control 904 on the first user interface are parameter setting controls.

S200, after detecting a signal source, if the signal source is a first channel, judging whether a code stream exists in the first channel. In an embodiment of the present application, the first channel may be a DTV channel. In the embodiment of the application, when the signal source is the first channel, it is determined that it is possible that the display device is playing the digital television program at this time. When the display device is playing the digital television program, the code stream must exist in the first channel. Therefore, in order to determine whether the current display device is playing the digital television program, when the signal source is the first channel, whether the code stream exists in the first channel is continuously judged.

In some embodiments, in step S300, when the signal source is a first channel and a code stream exists in the first channel, the code stream is analyzed to obtain first time information, where the first time information includes first time zone information.

In some embodiments, the code stream includes video data, first time information, and the like. And the display equipment analyzes the received code stream and plays the corresponding video content. In addition, the first time information in the code stream corresponds to the time zone information to which the digital television program belongs, the first time information in the code stream corresponding to the digital television program in different time zones is different, and the first time information comprises the first time zone information.

S400, controlling the position corresponding to the time zone setting control to display the first time zone information, setting the time zone setting control to be in a first display state, and setting the parameter setting control to be in a second display state, so as to distinguish the time zone setting control from the parameter setting control through the first display state and the second display state.

In the embodiment of the application, in order to facilitate a user to know a source of the current time displayed by the display device, when a signal source of the display device is a first channel and a code stream exists in the first channel, a first display state of the time zone setting control is controlled to be displayed, and the first display state is different from a second display state of the parameter setting control.

In some embodiments, setting the set time zone control to a first display state comprises: the time zone setting control is positioned between the two parameter setting controls; and when a fourth instruction that the focus moves towards the direction of the time zone setting control from the time parameter setting control positioned on one side of the time zone setting control is received, controlling the focus to directly move to the time parameter setting control positioned on the other side of the time zone setting control.

Illustratively, as shown in FIG. 10, when the focus is on the set time control 1003, the user presses a key on the control, illustratively a "down key," at which time the focus moves directly to the use 24h control 1005.

In some embodiments, the second display state is that the focus can be moved onto the control. Illustratively, in FIG. 10, when the focus is on the set date control 1002, the user presses a key on the control, illustratively a "down key," which moves the focus down to the set time control 1003.

In some embodiments, there are only two controls on the first user interface, including a set parameter control and a set time zone control located below the set parameter control.

And when a sixth instruction that the focus moves towards the direction of the time zone setting control from the parameter setting control is received, controlling the focus not to move, namely the focus is not positioned on the time zone setting control.

In some embodiments, setting the set time zone control to a first display state comprises: and when a fifth instruction for selecting the set time zone control is received, not executing the operation corresponding to the selected set time zone control.

Illustratively, as shown in FIG. 10, when the user moves the focus to the set time zone control 1004 and presses the confirmation key on the control device, a fifth instruction is generated to select the set time zone control, but the first user interface is unchanged.

In some embodiments, the second display state is that a certain control is selected, and an operation corresponding to the selected control is executed. Illustratively, as shown in fig. 10, when the user moves the focus to the set date control 1002 by using the control device and presses the enter key on the control device, the set date control is selected, and the corresponding operation is performed, the time corresponding to the set date control is modifiable, i.e., the time corresponding to the set date control can be modified as required, i.e., the time corresponding to 23 days, 3 months, 2022 years.

In some embodiments, when the set time zone control is in the first display state, the first time zone information displayed at the position corresponding to the set time zone control is not changeable.

It should be noted that, when jumping to the first user interface displayed with the first time zone information, the displayed first time zone information is the current locally stored time zone information. In some embodiments, the locally stored time zone information is initially set time zone information if the user has not changed the first time zone information in the past. If the user changes the first time zone information before jumping to the first user interface, the locally stored time zone information is the time zone information changed by the user last time.
