The power supply source may supply power to the display device 200 through power input from an external power source under the control of the controller 250.

In some embodiments, the display device 200 may receive user input operations through the communicator 220. For example, when communicator 220 is a touch component, the touch component may together with display 260 form a touch screen. On the touch screen, a user can input different control instructions through touch operation, for example, the user can input touch instructions such as clicking, sliding, long pressing, double clicking and the like, and different touch instructions can represent different control functions.

To implement the different touch actions, the touch assembly may generate different electrical signals when the user inputs the different touch actions, and transmit the generated electrical signals to the controller 250. The controller 250 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features.

For example, when a user enters a click touch action at any program icon location in the display interface of an application, the touch assembly 220 will sense the touch action and thereby generate an electrical signal. After receiving the electrical signal, the controller 250 may determine the duration of the level corresponding to the touch action in the electrical signal, and recognize that the user inputs the click command when the duration is less than the preset time threshold. The controller 250 then extracts the location features generated by the electrical signals to determine the touch location. When the touch position is within the application icon display range, it is determined that a click touch instruction is input by the user at the application icon position. Accordingly, the clicking touch instruction is used for executing the application program corresponding to the running program chart or switching the function of the display interface in the current scene, that is, the controller 250 may start the running application program or control the display interface in the switching application program.

In some embodiments, the communicator 220 may also be an external control component, such as a mouse, remote control, or the like, which may establish a communication connection with a display device. When the user performs different control operations on the external control component, the external control component may generate different control signals in response to the control operations of the user and transmit the generated control signals to the controller 250. The controller 250 may perform feature extraction on the received control signal to determine a control function to be performed by the user according to the extracted features.

For example, when a user clicks a left mouse button at any position in a display interface of an application program through the external control component, the external control component can sense a control action to generate a control signal. After receiving the control signal, the controller 250 may control the stay time of the action at the position according to the control signal, and identify that the click command is input by the user through the external control component when the stay time is less than the preset time threshold. The clicking instruction is used for opening a corresponding interface of the application program or switching a display interface in the application program under the current scene, or controlling the position of a mouse cursor.

In some embodiments, the communicator 220 may also be a control component, such as a desktop computer, coupled to the display 260, which may be a keyboard coupled to the display. The user can input different control instructions such as clicking, switching and other operation instructions through the keyboard.

Illustratively, the user may input a click command, a switch command, etc. through the corresponding shortcut key. For example, the user may trigger the sliding operation by selecting the "Tab" key and the direction key, that is, when the user selects the "Tab" key and the direction key on the keyboard at the same time, the controller 250 may receive the key signal, determine that the user triggers the operation of performing the switching operation in the direction corresponding to the direction key, and then, the controller 250 may control to turn or scroll the display interface in the media presentation page to display the corresponding media options.

The following describes in detail a display control method based on a display device according to an embodiment of the present invention with reference to fig. 4.

The display control method provided by the embodiment of the present invention may be applied to the display device 200 as shown in fig. 1, and the display device 200 may include a display 260, a communicator 220, and a controller 250 coupled to the display 260 and the communicator 220, respectively.

According to the display control method provided by the embodiment, when the display is controlled to display the interface corresponding to the first channel, the display device can respond to the first starting operation input by the user to start the first time shift function of the display device and record the interface corresponding to the first channel, then respond to the first switching operation input by the user through the communicator to determine whether the second application program supports the background time shift function, and if the second application program supports the background time shift function, based on the first switching operation, control the display to display the interface of the second application program and record the interface corresponding to the first channel. The user can switch the application programs according to the own demands without interrupting the time shifting function of the application programs before switching, so that the recording continuity of the channel interface of the application programs before switching can be ensured, and when the user switches back to the original application program, the continuity of the watching content can be ensured by watching the recorded video, thereby improving the watching experience of the user.

As shown in fig. 4, the controller 250 is configured to perform the following steps S410 to S420:

step S410: when the display is controlled to display an interface corresponding to the first channel, a first time shift function of the display device is started in response to a first starting operation input by a user, and the interface corresponding to the first channel is recorded.

In this embodiment, the time shift function is a mode of watching a live program, and by using the time shift function, the controller can record the live program first and then buffer the live program, and when a user needs to watch, the user can read a recorded video from the buffer to watch, so that the function of recording and playing immediately can be realized. The first time shift function is a mode supporting the time shift function, corresponds to a strong time shift mode of the display device, and can control an application program running in the background to continue to run the time shift function when the display device opens a plurality of application programs.

The interface corresponding to the first channel refers to an interface displayed when the first channel is played, which may be a playing interface of a television program of the first channel, or a display screen corresponding to the first channel, such as a main page of the first channel, and the like. The first opening operation refers to an operation of opening a first time shift function of the display device, which is input by a user, and may be that the user selects a corresponding function opening control in a display screen on the display, for example, a "permanent time shift function" option is triggered, that is, when the user selects to open the "permanent time shift function" option, the controller detects that the user inputs the first opening operation. Alternatively, the first opening operation may be triggered by the user through a control component externally connected to the display, such as a mouse, a keyboard, a remote controller, or the like, for example, when the user uses the remote controller to control the display to display a "system setup" interface and then selects an option of opening a "permanent time shift function" in the interface, the controller detects that the user inputs the first opening operation, or the user may also input a voice control instruction through a voice control function of the control component or the display device to trigger the first opening operation.

The display device may receive a first start operation input by a user when the display device is controlled to display an interface corresponding to the first channel, and may start a first time shift function of the display device in response to the operation when the display device receives the first start operation input by the user. The controller may start recording an interface corresponding to the first channel while the first time shift function is turned on.

It should be noted that, when the controller records the interface corresponding to the first channel, the display may display the interface corresponding to the first channel, or may not display the interface corresponding to the first channel. That is, the controller may record the interface corresponding to the first channel by recording a display screen of the display, or may obtain the media file of the interface corresponding to the first channel.

Step S420: and responding to a first switching operation input by a user through the communicator, if the second application program supports a background time-shifting function, controlling the display to display an interface of the second application program based on the first switching operation, and recording the interface corresponding to the first channel.

The first switching operation is used for switching the display device from a first application program to a second application program, wherein the first application program comprises a first channel. That is, the first application may include a plurality of channels, and the first channel may be any one of the channels in the first application. The first switching operation may be used to switch the display device from any one of the channels in the first application to the second application, such as any one of the video classification pages or a certain video play page of the second application, etc. Correspondingly, the first switching operation may be triggered by the user selecting a program switching control in a display screen on the display, or may be triggered by the user through a control component externally connected to the display, such as a keyboard, a remote controller, or the like, or the user may input a voice control instruction through a voice control function of the control component or the display device, so as to trigger the first switching operation.

The background time shift function refers to a time shift function that an application program runs in the background at the same time, and at this time, the application program can also execute the time shift function although running in the background, for example, the display device can still record an interface corresponding to the application program running in the background.

When the display device receives a first switching operation input by a user through the communicator, the display device indicates that the user wants to switch a first channel in the first application program to a certain interface in the second application program, in order to determine whether the first channel can continue to operate the time shifting function, the controller can control the display to display the interface of the second application program in response to the first switching operation input by the user when the second application program supports the background time shifting function, and simultaneously, the display device operates in a background time shifting state, namely, the first application program operates in the background, while the interface of the second application program is displayed, and the controller can continue to perform the time shifting function related to the first application program, namely, record the interface corresponding to the first channel.

In some embodiments, the controller may determine whether the second application supports the background time-shift function upon receiving the first switching operation input by the user.

For example, the controller may determine whether the first application program can run the background time-shift function while the second application program is running in the background according to the types of the first application program and the second application program, to determine whether the second application program supports the background time-shift function. If the first application program can run the background time shift function while the second application program runs in the foreground, the second application program supports the background time shift function, otherwise, the second application program does not support the background time shift function.

The types of the first application program and the second application program can be configured by a developer in the development process, and can comprise a type supporting a background time-shifting function and a type not supporting the background time-shifting function.

Through the steps S410 to S420, when the first switching operation of the user is received, the display device may control the first application program to enter the background for running, and when the second application program supports the background time shift function, the time shift function of the first application program may be run in the background, and the time shift function of the first application program may not be affected by the switching of the first application program to the background, and the interface corresponding to the first channel may be recorded through the time shift function of the first application program, so that when the user needs to review the first channel, the user may watch the first application program by recording the video and switch to the picture of the first channel when the user desires to review the first channel, so that the continuity of watching the video by the user may be ensured, and the user may watch the recorded video at any time without being limited by the timeliness of the program.

In some embodiments, the recorded video of the interface corresponding to the first channel may be stored in an internal hard disk of the display device, or may be stored in another storage device connected to the display device, such as a USB memory, a hard disk, or the like. That is, the display device may support a time shift function of the internal hard disk, and may also support a time shift function of the external storage device.

The user may set the maximum storage space for the recorded video, for example, the minimum storage space of the built-in hard disk may be set to 10G, the storage space of the external storage device may be set to 20G, or the maximum storage space of the storage device may be directly set according to the storage device type of the display device. When the storage space of the display device occupied by the recorded video reaches the maximum, the cyclic recording can be started, namely, the recorded video stored earliest is deleted according to the time sequence of the recorded video so as to store the latest recorded video.

In some embodiments, referring to fig. 5, the controller may also perform the following method:

step S510: if the second application program does not support the background time shift function, a time shift state of the display device before receiving the first switching operation input by the user is determined.

Wherein the time shift states include an implicit time shift state and an explicit time shift state. The hidden time shift state means that the time shift function is in a hidden state, and a user cannot perceive that the display device is running the time shift function; the explicit time shift state means that the time shift function is in an explicit state, and a user can learn that the display device is running the time shift function through a time shift information bar or a time shift window in an interface displayed on the display, as shown in fig. 6, a time shift window 610 may also be displayed on an interface 600 corresponding to the first channel, where the time shift window 610 may further include options such as a video name, a video playing progress bar, a played duration, a total playing duration, a recording key, a fast forward key, a fast backward key, and the like. In the explicit time shift state, the user may also control the interface being displayed on the display to perform time shift through a time shift information bar or a control option in a time shift window, for example, the user may drag a progress bar in the time shift window to adjust the playing progress of the video played on the display, or may also control the video played on the display to perform fast forward by selecting a "fast forward" key in the time shift window.

If the second application program does not support the background time shift function, it indicates that the first application program cannot continue to run the time shift function in the background after switching to the second application program, at this time, in order to facilitate switching of the application program, the controller may further determine whether the time shift state of the display device before receiving the first switching operation input by the user is an implicit time shift state or an explicit time shift state.

For example, the controller may determine whether the display device is in an implicit time shift state or an explicit time shift state according to whether the display device displays a time shift information bar or a time shift window on the display before receiving a first switching operation input by the user. When the time shift information bar or the time shift window is not displayed on the display, the display device can be determined to be in an implicit time shift state, and when the time shift information bar or the time shift window is displayed on the display, the display device can be determined to be in an explicit time shift state.

Step S520: if the display device is in the implicit time shift state before receiving the first switching operation input by the user, controlling the display to display the interface of the second application program, and stopping recording the interface corresponding to the first channel.

If the display device is in an implicit time shift state before receiving the first switching operation input by the user, it is indicated that the display device is time-shifted, i.e. recording the interface corresponding to the first channel, before the user inputs the first switching operation, but the user does not perceive the recording process.

Therefore, when the first switching operation input by the user is received, the controller can control the display to directly display the interface of the second application program to realize the switching of the application program, and meanwhile, before the first switching operation is received, the user does not know that the display equipment is recording the interface of the first channel, so that the time shift of the interface corresponding to the first channel in the first application program can be automatically closed when the interface of the second application program is switched to, namely, the recording of the interface corresponding to the first channel is stopped.

In this way, when the first application program runs in the implicit time shift state, if the first switching operation input by the user is received, the first switching operation is responded, the second application program is directly switched to, and the switching of the application programs is realized.

Step S530: if the display device is in an explicit time shift state before receiving the first switching operation input by the user, controlling the display to display the stop time shift prompt information, and controlling the display to display an interface of the second application program and stopping recording the interface corresponding to the first channel in response to the confirmation of the stop time shift operation input by the user through the stop time shift prompt information.

If the display device is in an explicit time-shifting state before receiving the first switching operation input by the user, it is indicated that the display device is time-shifting, that is, recording the interface corresponding to the first channel, before the user inputs the first switching operation, and the user may also control the interface corresponding to the first channel to perform time shifting, such as fast forward, pause, etc., through a time-shifting information bar or a time-shifting window displayed on the display. That is, in the explicit time shift state, the user can know that the time shift function is in operation through a time shift information bar or a time shift window displayed on the display.

At this time, when the first switching operation input by the user is received, the controller may control the display to display the stop time shift prompt information, so that the user may determine whether to close the time shift function of the first application program and switch to the second application program.

Referring to fig. 7, in the interface corresponding to the first channel, stop time shift prompt information 710 may be displayed, where the stop time shift prompt information 710 further includes two options of "confirm stop" and "cancel", and if the user selects the "confirm stop" option, which indicates that the user inputs an operation of confirming to stop time shift through the stop time shift prompt information, the controller may control the display to display the interface of the second application program, and simultaneously stop recording the interface corresponding to the first channel, that is, close the time shift of the interface corresponding to the first channel in the first application program. If the user selects the "cancel" option, indicating that the user does not want to stop the time shift of the interface corresponding to the first channel in the first application, the program switch may be canceled at this time to continue the time shift of the interface corresponding to the first channel in the first application.

In some embodiments, after controlling the display to display the interface of the second application program and recording the interface corresponding to the first channel based on the first switching operation, the controller may further perform the following method:

And responding to a second switching operation input by the user through the communicator, controlling the display to switch back to the interface corresponding to the first channel, and recording the interface corresponding to the first channel.

Wherein the second switching operation may be used to switch the display device from the second application back to the first application. That is, after the user switches the interface corresponding to the first channel in the first application to the second application through the first switching operation, the second application may be further switched back to the interface corresponding to the first channel in the first application through the second switching operation. Correspondingly, the second switching operation can also be triggered by the user selecting a program switching control in a display picture on the display, or can be triggered by a control component externally connected with the display, such as a keyboard, a remote controller and the like, or can be triggered by the user through a voice control function of the control component or the display device.

When the user triggers the second switching operation, the controller can receive the second switching operation input by the user through the communicator, and in order to switch the application program back to the first application program, the controller can control the display to switch back to the first application program and present an interface corresponding to the first channel, so that the user can continue to watch the first channel. Meanwhile, the display device can start the time shifting function of the first application program so as to record the interface corresponding to the first channel.

Thus, after the user switches the second application program back to the first application program, the user can continue to operate the time shifting function of the first application program, record the interface corresponding to the first channel, and realize the connection of the time shifting function.

Fig. 8 shows a flowchart of yet another display control method provided in this embodiment, as shown in fig. 8, may include the following steps:

step S810: and receiving a first switching operation input by a user when the display device is determined to be in the implicit time shift state.

Step S820: upon receiving the first switching operation input by the user, it is determined whether the second application supports the background time-shift function, if so, step S830 is performed, and if not, step S840 is performed.

When the display device is in the implicit time shift state, if a first switching operation input by a user is received, the user is indicated to trigger the switching of the application program, and at this time, whether a second application program which the user wants to switch to supports a background time shift function can be further judged.

If the second application supports the background time shift function, it indicates that the display switches the first application to the background, and when the second application switches to the foreground, the first application may operate the background and simultaneously operate the time shift function, so step S830 may be executed to control the display to display an interface of the second application and record an interface corresponding to the first channel based on the first switching operation. Otherwise, if the second application program does not support the background time shift function, it indicates that the display is switching the first application program to the background, and when the second application program is switching to the foreground, the first application program cannot operate the time shift function while operating in the background, so step S840 may be executed, so that the display may switch to the interface of the second application program, and stop the time shift function of the interface corresponding to the first channel in the first application program, that is, stop recording the interface corresponding to the first channel.

Step S830: based on the first switching operation, the display is controlled to display the interface of the second application program, and the interface corresponding to the first channel is recorded.

When the display is controlled to display the interface of the second application program and the interface corresponding to the first channel is recorded, the display equipment is in a background time shifting state, namely, when the first application program runs in the background, the time shifting function is operated.

Step S840: and controlling the display to display the interface of the second application program, and stopping recording the interface corresponding to the first channel.

Step S850: a second switching operation input by the user through the communicator is received.

And when receiving a second switching operation input by the user, indicating that the user wants to switch the second application program back to the interface corresponding to the first channel in the first application program.

Step S860: and controlling the display to switch back to the interface corresponding to the first channel, and recording the interface corresponding to the first channel.

When the second switching operation is received, in order to facilitate the user to continuously watch the interface corresponding to the first channel, the controller may control the display to switch back to the interface corresponding to the first channel in the first application program and continuously record the interface corresponding to the first channel, at this time, the display device is in an implicit time shift state, that is, the first application program operates in the foreground and operates the time shift function, but the user does not perceive that the time shift function is in the operating state.

In some embodiments, after switching back to the interface corresponding to the first channel through steps S810 to S860, the controller may clear the video of the interface corresponding to the first channel recorded before, and restart recording the interface corresponding to the first channel when switching back to the interface corresponding to the first channel. Or, the controller may also keep the video of the interface corresponding to the first channel recorded before, and when switching back to the interface corresponding to the first channel, continue recording the interface corresponding to the first channel.

Fig. 9 shows a flowchart of yet another display control method provided in this embodiment, as shown in fig. 9, may include the following steps:

step S910: upon determining that the display device is in the dominant time-shifted state, a first switching operation is received that is input by a user.

Step S920: upon receiving the first switching operation input by the user, it is determined whether the second application supports the background time-shift function, if so, step S930 is performed, and if not, step S940 is performed.

When the display device is in the dominant time shift state, if a first switching operation input by a user is received, the user is indicated to trigger the switching of the application program, and at this time, whether a second application program to which the user wants to switch supports a background time shift function can be further judged.

If the second application supports the background time shift function, it indicates that the display switches the first application to the background, and when the second application switches to the foreground, the first application may operate the background and simultaneously operate the time shift function, so step S930 may be executed to control the display to display an interface of the second application and record an interface corresponding to the first channel based on the first switching operation. Otherwise, if the second application program does not support the background time shift function, it indicates that the display is switching the first application program to the background, and when the second application program is switching to the foreground, the first application program may not operate the time shift function while operating in the background, so step S940 may be executed, and the display is controlled to display the stopping time shift prompt information, so that the user may select whether to stop the time shift function of the interface corresponding to the first channel in the first application program through the stopping time shift prompt information, so as to switch to the interface of the second application program.

Step S930: based on the first switching operation, the display is controlled to display the interface of the second application program, and the interface corresponding to the first channel is recorded.

Step S940: and controlling the display to display the stop time shift prompt information.

Step S950: and responding to the operation of stopping time shifting by confirming that the user stops the time shifting prompt information input, controlling the display to display the interface of the second application program, and stopping recording the interface corresponding to the first channel.

When the user selects to confirm the operation of stopping the time shift by stopping the time shift prompt information, the user is indicated to want to switch to the second application program, and the display device does not need to continuously execute the time shift function of the first application program, so that the controller can control the display to display the interface of the second application program, and stop the time shift function of the first application program, namely, stop recording the interface corresponding to the first channel.

Step S960: a second switching operation input by the user through the communicator is received.

Step S970: and controlling the display to switch back to the interface corresponding to the first channel, and recording the interface corresponding to the first channel.

Correspondingly, when the second switching operation is received, in order to facilitate the user to continuously watch the interface corresponding to the first channel, the controller may control the display to switch back to the interface corresponding to the first channel in the first application program and continuously record the interface corresponding to the first channel, at this time, the display device is in an implicit time shift state, that is, the first application program operates in the foreground and operates the time shift function, but the user does not perceive that the time shift function is in an operating state.

In some embodiments, after switching back to the interface corresponding to the first channel through steps S910 to S970, the controller may keep the video of the interface corresponding to the first channel recorded before, and continue recording the interface corresponding to the first channel when switching back to the interface corresponding to the first channel. Or, the controller may also clear the video of the interface corresponding to the first channel recorded before, and restart recording the interface corresponding to the first channel when switching back to the interface corresponding to the first channel.

By the method, the controller can control the display equipment to switch between different application programs according to the switching operation of the user and enter different time shifting states, so that the time shifting function connection between different application programs can be opened, the time shifting function of the application program before the switching is not required to be forcibly stopped, the user does not need to execute excessive operation, the operation requirement of the user can be met, the continuity of the time shifting function of the application program can be ensured, and convenience is provided for the subsequent user to watch the recorded video generated by the time shifting function.

In some embodiments, referring to fig. 10, the controller may also perform the following method:

Step S1010: and when the display is controlled to display the interface corresponding to the first channel, responding to a second starting operation input by a user, and starting a second time shifting function of the display device.

The second time shift function is another mode supporting a time shift function, which corresponds to a weak time shift mode of the display device, and can be selected by the user to stop time shift when the display device switches the displayed interface, so as to complete the switch. The second opening operation refers to an operation of opening the second time shift function of the display device, which is input by the user, and can be triggered by the user selecting a corresponding function opening control in a display screen on the display, for example, when the user selects to close a 'permanent time shift function' option, the controller detects that the user inputs the second opening operation. Alternatively, the second opening operation may be triggered by the user through a control component externally connected to the display, such as a keyboard, a remote controller, or the like, for example, when the user uses the remote controller to control the display to display a "system setup" interface, and then selects an option of turning off the "permanent time shift function" in the interface, the controller detects that the user inputs the second opening operation.

When the display is controlled to display the interface corresponding to the first channel, if a second starting operation input by a user is received, the display device is indicated to start a weak time shift mode, namely, the second time shift function is started.

Step S1020: and responding to the time shift control operation input by the user, and controlling the interface corresponding to the first channel to display.

The time shift control operation refers to an operation of displaying a time shift information bar or a time shift window, which is input by a user, and the user can select a corresponding time shift option in an interface displayed on the display, for example, the time shift bar triggers the time shift control operation, or can also input key operation through a control component externally connected with the display, so as to trigger the time shift control operation.

After the display device starts the second time shifting function, the display device enters a common time shifting state, at this time, if time shifting control operation input by a user is received, which indicates that the user needs to check the time shifting state of the first application program or control an interface corresponding to the first channel to perform time shifting, at this time, the controller can control the first application program to enter an explicit time shifting state, at this time, a time shifting information bar or a time shifting window can be displayed on the display, and the user can control the interface corresponding to the first channel to perform time shifting through the time shifting information bar or the time shifting window. Taking the interface corresponding to the first channel as a video playing interface as an example, a user can check the progress of playing the video through a time shift information bar or a time shift window, and can control the fast forward of the playing video through operation options on the interface.

By the method, the second time shifting function of the display device can be started in response to the second starting operation input by the user, then when the time shifting control operation input by the user is received, the display is controlled to enter the dominant time shifting state, the dominant time shifting control based on the time shifting function of the display device can be realized, and the user can conveniently check the time shifting state of the application program.

In some embodiments, in a normal time shift state, if the user needs to switch the application program or switch the channel in the same application program, stopping time shift prompt information may be displayed when a switching operation input by the user is received, and when the user selects to stop the time shift function of the previous application program or the previous channel by stopping the time shift prompt information, the user switches to the next application program or the next channel. Otherwise, if the user selects to continue the time shift function of the previous application program or the previous channel by stopping the time shift prompt information or does not operate within the preset time period of displaying the time shift stop prompt information, the time shift function of the previous application program or the previous channel can be continued without switching the application program or the channel.

In other words, according to whether the display device starts the first time shift function or the second time shift function, the time shift control manner of the display device is different, when the display device starts the first time shift function, and when the application program is switched, if the application program to be switched supports the background time shift function, the display device can be directly switched to the corresponding application program from the implicit time shift state without querying the user. When the display device starts the second time shift function, the user needs to ask whether the user needs to stop the previous time shift interface or not whether the user needs to stop time shift no matter the user switches the application program or the channel in the same application program, and the user can switch to the next application program or the channel when the time shift function of the previous time shift interface needs to be stopped. It should be appreciated that the first time shift function and the second time shift function cannot be turned on simultaneously.

Through the two modes, a user can select to start a strong time shift mode or a weak time shift mode to control the display equipment to execute different time shift control modes, so that flexible switching of time shift control is realized, and the display equipment is more suitable for own requirements.

In order to facilitate the user to view the time shift state of the first channel, the controller may control the interface of the first channel to perform time shift, in some embodiments, after starting the first time shift function of the display device in response to the first start operation input by the user and recording the interface corresponding to the first channel, the controller may also control the interface corresponding to the first channel to display in response to the time shift control operation input by the user.

As described above, the time shift control operation refers to an operation of displaying a time shift information bar or a time shift window, which is input by the user. By way of example, the time shift control operation may include an operation of controlling the display of content on the interface to pause, play, fast forward, fast reverse, double-speed play, etc.

When the user inputs a time shift control operation through a time shift information bar or a time shift window, the controller can respond to the time shift control operation to control an interface corresponding to a first channel displayed on the display to display. For example, when the user inputs a play pause operation through the time shift information bar, the controller may control the video in the interface corresponding to the first channel to pause in response to the operation.

Therefore, when the display enters the dominant time shifting state, the user can control the interface on the display to execute corresponding time shifting operation, so that the user can flexibly select the video playing mode.

In some embodiments, the interface corresponding to the first channel may be used to play a first channel program, where the first channel program is any program corresponding to the first channel, and the time shift control operation may include at least one of a fast forward operation, a fast reverse operation, a play pause operation, and a play operation, and thus, referring to fig. 11, the controller may further perform any one of the following methods in steps S1110 to S1140:

step S1110: and controlling the first channel program to perform fast forward in response to the fast forward operation input by the user.

Step S1120: and controlling the first channel program to fast-back in response to the fast-back operation input by the user.

For example, when the user selects and presses the "fast forward" key in the time shift information bar on the interface corresponding to the first channel, the controller may control the first channel program to fast forward, and as the time for which the user presses the "fast forward" key increases, the fast forward speed of the first channel program may increase. When the user selects and presses the fast-rewinding key in the time-shift information bar on the interface corresponding to the first channel, the controller can control the first channel program to fast-rewind, and the fast-rewinding speed of the first channel program can be continuously increased along with the continuous increase of the time when the user presses the fast-rewinding key.

Step S1130: and controlling the first channel program to pause playing in response to the playing pause operation input by the user.

Step S1140: and controlling the first channel program to start playing in response to the playing operation input by the user.

For example, when the user selects a "play pause" key on the interface corresponding to the first channel, the controller may control the first channel program to pause playing. When the user selects the "play pause" key again, the controller may control the first channel program to continue playing.

By the method, when the display is in the dominant time shift state, the user can control the first channel program to play, so that the video playing requirement of the diversity of the user can be met, and the watching convenience is provided for the user.

In some embodiments, referring to fig. 12, the controller may also perform the following method:

step S1210: in response to a third switching operation input by the user through the communicator, a stop time shift prompt message is displayed, the third switching operation being for switching the display device from the first channel to the second channel.

Wherein the first application may include a second channel. That is, the second channel is another channel different from the first channel in the first application program. A third switching operation may be used to switch the display device from one channel to another channel of the same application. That is, the user can switch the first channel in the first application to the second channel through the third switching operation. Correspondingly, the third switching operation can also be triggered by the user selecting a program switching control in a display picture on the display, or can be triggered by the user through a control component externally connected with the display, such as a keyboard, a remote controller and the like.

Upon receiving a third switching operation entered by the user, it is indicated that the user triggered the channel switching operation, since the channel switching corresponds to the same application, which can only support time shifting of one channel. Therefore, in order to facilitate the user to switch channels, the controller may control the display to display stop time shift prompt information so that the user may select whether the time shift of the first channel needs to be stopped to switch to the third channel.

Step S1220: and stopping recording the interface corresponding to the first channel and switching to the interface corresponding to the second channel in response to the operation of stopping time shifting by the confirmation of stopping time shifting prompt information input by the user.

When the user confirms the operation of stopping time shifting through the time shifting stopping prompt information input, the user can be determined to determine to switch channels, and at the moment, the controller can control the display device to stop recording the interface corresponding to the first channel and switch to the interface corresponding to the second channel. Therefore, when the channel is switched, the user can conveniently select whether to stop time shifting of one channel or not so as to switch to the other channel.

After switching to another channel, the controller can automatically start time shifting to the other channel, i.e. start recording the interface corresponding to the other channel.

Fig. 13 is a schematic diagram showing a switching of a time shift state according to an embodiment of the present invention, where, as shown in fig. 13, a user may turn on a first time shift function of a display device through a first turn-on operation, where the first time shift function corresponds to a strong time shift function of the display device, and turn on a second time shift function of the display device through a second turn-on operation, where the second time shift function corresponds to a weak time shift function of the display device.

If the display device is in an implicit time shift state, namely the first application is in time shift, but not perceived by a user, when a first switching operation input by the user is received, the display device is indicated to want to switch the first application to the second application, at this time, the controller can control the display device to enter a background time shift state, namely the first application is operated in the background, and simultaneously the time shift function is operated so as to continuously record an interface corresponding to the first application, and the second application is operated in the foreground, and the display device displays the interface of the second application. Then, when a second switching operation input by the user is received, the user is indicated to want to switch the interface of the second application program back to the first application program, at this time, the controller can control the display device to enter an implicit time shift state, that is, the first application program operates in the foreground, the display displays the interface of the first application program, and at the same time, the time shift function is operated to record the interface corresponding to the first application program, at this time, the second application program can operate in the background or can be closed.

When the display device is in the implicit time shift state, if the time shift control operation input by the user is received, the controller can control the display device to enter the explicit time shift state, and at this time, the user can perform the time shift operation according to the time shift information bar or the time shift window displayed on the display, for example, control the playing, the pause or the fast forward of the video interface of the first application program, and the like. Then, if a first switching operation input by the user is received, the controller may execute the same time shift control method to make the display device enter a background time shift state, that is, the first application program is operated in the background, and at the same time, the time shift function is operated to continue recording the interface corresponding to the first application program, and the second application program is operated in the foreground, and the display displays the interface of the second application program.

Under the condition that the second time shifting function is started, the display device is in a common time shifting state, and background time shifting is not supported, so that when an application program or a channel in the same application program is switched, the time shifting function of a previous application program or a channel is required to be stopped, and the next application program or the channel can be switched.

To facilitate the generation of recorded video of live programming for viewing by a user, in some embodiments, referring to FIG. 14, the controller may further perform the following method:

Step S1410: and if the reserved recording time of the target multimedia resource is reached, receiving recording selection operation input by a user through the communicator.

The target multimedia resource is any multimedia resource corresponding to the first application program or the second application program, is a multimedia resource reserved by a user, and can be composed of any one or more of pictures, characters, sound, video, animation and derived expression forms. The recording selection operation refers to an operation of confirming recording or canceling recording entered by a user.

After the user reserves the reservation of the target multimedia resource, the controller may start a countdown, and when the reserved recording time of the target multimedia resource is reached, the controller may receive a recording selection operation input by the user through the communicator in a next preset period.

For example, when the scheduled recording time of the target multimedia asset is reached, the controller may control the display to display recording reminding information, where the recording reminding information may include selection controls, such as options of "confirm recording" and "cancel recording", and the user may input a recording selection operation by clicking the "confirm recording" option or the "cancel recording" option.

Step S1420: if the recording selection operation indicates to start recording, the display device is controlled to stop recording the interface corresponding to the first channel and start recording the target multimedia resource in response to the recording selection operation.

For example, when the user clicks the "confirm recording" option in the recording reminding information, the controller may determine that the recording selection operation indicates to start recording, at this time, the controller may control the display device to stop recording the interface corresponding to the first channel and start recording the target multimedia asset in response to the recording selection operation.

It should be noted that, when the display device is controlled to stop recording the interface corresponding to the first channel and start recording the target multimedia resource, the target multimedia resource may be displayed on the display, or the interface corresponding to the first channel may be continuously displayed, or the interface corresponding to the target multimedia resource and the first channel may be simultaneously displayed, for example, the interface corresponding to the first channel may be displayed on the display in a full screen manner, and the target multimedia resource may be displayed on the display in a form of small window playing.

Step S1430: and if the recording selection operation indicates to cancel recording, canceling the recording target multimedia resource so as to continue recording the interface corresponding to the first channel.

For example, when the user clicks the "cancel recording" option in the recording reminding information, the controller may determine that the recording selection operation indicates to cancel recording, at this time, the controller may control the display device to continue recording the interface corresponding to the first channel and cancel recording of the target multimedia asset in response to the recording selection operation.

In some cases, if the user does not perform any operation within a preset period of time, such as 2 minutes from the start of displaying the recording reminder, the recording selection operation is a null value indicating that the recording selection operation indicates that recording is canceled.

By the method, the user can reserve the recording of the target multimedia resource in advance according to the own requirement, so that the user can watch the recorded video of the target multimedia resource when watching conveniently, and great convenience can be provided for the user.

In this embodiment, during the operation of the time shift function, the controller may receive a video viewing operation of the interface corresponding to the application program running the time shift function from the user, regardless of the time shift state of the display device. Upon receiving a video viewing operation input by a user, the controller may generate a recorded video of an interface corresponding to a corresponding application in response to the operation. Specifically, referring to fig. 15, the following method may be included:

Step S1510: a video viewing operation of a user is received while the application is running the time-shift function.

During the time-shifting function of the application program, whether the application program is running in the foreground or the background, the controller may receive the video viewing operation input by the user, for example, when the user inputs a voice control command "i want to see the XX video of the XX application program" through the external component, if the application program is in the time-shifting function, the video viewing operation of the XX video input by the user in the application program may be determined.

Step S1520: and converting the buffer data of the interface corresponding to the application program generated by the time shifting function into a recorded video.

When the application program runs the time shift function, the application program can record a corresponding interface, such as an interface displayed on a display when the time shift function is started, and generate cache data. Upon receiving a video viewing operation from a user, the controller may convert the buffered data into a recorded video in a video format.

Step S1530: and judging whether the conversion of the cache data is finished, if yes, executing step S1540, modifying the time shift state of the interface corresponding to the application program into a video recording state, and if not, executing step S1550, and detecting whether the conversion of the cache data is overtime.

Step S1540: and modifying the time shift state of the interface corresponding to the application program into a video recording state.

When the time shift state corresponding to the application program is changed to the video recording state, the video recording identification can be displayed on the interface corresponding to the application program, so that a user can know that the recorded video is generated and can watch at any time.

Step S1550: whether the conversion of the buffered data is overtime is detected, if yes, step S1560 is executed to stop the recorded video conversion operation, and if not, step S1530 is executed continuously to determine whether the conversion of the buffered data is completed.

Step S1560: the cached data conversion is stopped.

By the method, the recorded video can be controlled to be stored and converted, convenience is brought to the user for watching the recorded video, and the cache data can be flexibly stored according to the running condition of the display device and the operation requirement of the user, for example, if the user does not trigger the video watching operation all the time within the preset time after the cache data is generated, the user is indicated that the user may not have the requirement for watching the recorded video corresponding to the cache data, so that the cache data can be deleted after the preset time is reached, and the storage space is saved.

In summary, according to the display control method provided in this embodiment, when the display is controlled to display the interface corresponding to the first channel, the display device may start the first time shift function of the display device and record the interface corresponding to the first channel in response to the first start operation input by the user, and then control the display to display the interface of the second application based on the first switch operation and record the interface corresponding to the first channel in response to the first switch operation input by the user through the communicator when the second application supports the background time shift function. The user can switch the application programs according to the own demands without interrupting the time shifting function of the application programs before switching, so that the recording continuity of the channel interface of the application programs before switching can be ensured, and when the user switches back to the original application program, the continuity of the watching content can be ensured by watching the recorded video, thereby improving the watching experience of the user.
