Alternatively, the user can input user commands by inputting specific sounds or gestures, and the user input interface receives the user input commands by recognizing the sounds or gestures through the sensor.

[0066] In some embodiments, a "user interface" is a medium interface for interaction and information exchange between an application program or an operating system and a user, which realizes the conversion between the internal form of information and the form that the user can accept. The commonly used form of a user interface is a graphic user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an icon, a window, a control, etc. displayed on the display screen of an electronic device, wherein the control can include at least one of the following visual interface elements: an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a widget, etc.

[0067] In some embodiments, the user interface 265 is an interface (e.g., a physical button on the body of the display device, or the like) that can be used to receive a control input.

[0068] In some embodiments, the system of the display device can include a kernel, a shell, a file system, and an application program. The kernel, the shell, and the file system together form a basic operating system structure, which allows a user to manage files, run programs, and use the system. After power-on, the kernel is started, the kernel space is activated, the hardware is abstracted, the hardware parameters are initialized, the virtual memory is run and maintained, the scheduler, the signal, and the inter-process communication (IPC) are maintained. After the kernel is started, the shell and the user application program are loaded. The application program is compiled into machine code after being started, forming a process.

[0069] Referring to Figure 4 In some embodiments, the system is divided into four layers from top to bottom, namely, an application layer (referred to as "application layer" for short), an application framework layer (referred to as "framework layer" for short), an Android runtime and system library layer (referred to as "system runtime library layer" for short), and a kernel layer.

[0070] In some embodiments, at least one application program is run in the application layer, which can be a window (Window) program, a system setting program, or a clock program, etc. provided by the operating system; or an application program developed by a third-party developer. In a specific implementation, the application program package in the application layer is not limited to the above examples.

[0071] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications in the application layer. The application framework layer includes some pre-defined functions. The application framework layer is equivalent to a processing center that decides which application in the application layer to act. The application accesses resources in the system and obtains services of the system through the API interface during execution.

[0072] As shown in Figure 4 In the embodiments of the present application, the application framework layer includes managers (Managers) and content providers (Content Provider), wherein the managers include at least one of the following modules: an activity manager (ActivityManager) for interacting with all activities running in the system; a location manager (Location Manager) for providing access to system location services for system services or applications; a package manager (Package Manager) for retrieving various information related to application packages currently installed on the device; a notification manager (NotificationManager) for controlling the display and clearing of notification messages; and a window manager (Window Manager) for managing icons, windows, toolbars, wallpapers, and desktop components on the user interface.

[0073] In some embodiments, the activity manager is used to manage the life cycle of each application and the general navigation back function, such as controlling the exit, opening, back, etc. of the application. The window manager is used to manage all window programs, such as obtaining the size of the display screen, determining whether there is a status bar, locking the screen, intercepting the screen, controlling the display window change (such as reducing the display window, shaking the display, twisting the display, etc.), etc.

[0074] In some embodiments, the system runtime library layer provides support for the upper layer, i.e. the framework layer. When the framework layer is used, the Android operating system runs the C / C++ library contained in the system runtime library layer to realize the functions of the framework layer.

[0075] In some embodiments, the kernel layer is a layer between hardware and software. As shown in Figure 4 The kernel layer includes at least one of the following drivers: an audio driver, a display driver, a Bluetooth driver, a camera driver, a WIFI driver, a USB driver, an HDMI driver, a sensor driver (such as a fingerprint sensor, a temperature sensor, a pressure sensor, etc.), and a power supply driver, etc.

[0076] The hardware or software architecture in some embodiments can be based on the above-mentioned introduction in some embodiments, and can be based on other similar hardware or software architectures, as long as the technical solutions of the present application can be implemented.

[0077] In some embodiments, a video recording program can be installed on the display device to implement the video recording function. The video recording program can be a PVR (Personal Video Recorder) program, which can implement the PVR recording function. In order to avoid occupying a large amount of storage space of the display device by the video file, the PVR program can store the recorded video file in a storage connected to the display device, wherein the storage can be a disk or other storage device, and the present application takes the disk as an example for introduction. When the display device uses a new disk to store the recording file, the disk needs to be registered to check whether the performance of the disk meets the requirement of storing the recording file. In some embodiments, the user can have multiple disks to store the recording file. When the display device is connected to multiple disks at the same time, the display device selects the first inserted disk as the disk corresponding to the PVR program. However, in general, the first inserted disk is not the disk that the user wants to use.

[0078] To solve the above technical problem, the present application provides a video recording method according to the need of registering the storage when the display device performs video recording, which is described as follows. Figure 5 The method can include the following steps:

[0079] Step S110: receiving a video recording request input by the user.

[0080] In some embodiments, the video recording request can be a request generated by the instruction of starting the video recording program. The user inputs the instruction of opening the PVR recording program on the display device, and the display device can generate the video recording request according to the instruction of opening the PVR recording program.

[0081] Step S120: in response to the video recording request, setting the storage with the latest registration time among the connected storages as the target storage.

[0082] In some embodiments, the display device has connected a storage before receiving the video recording request. At this time, the display device can directly set the storage as the target storage for video recording.

[0083] In some embodiments, the display device has connected multiple storages before receiving the video recording request. At this time, the display device can select one storage as the target storage for video recording.

[0084] In some embodiments, in order to optimize the user experience, the display device can set the target storage by referring to the following method:Figure 6 comprises steps S121-S127.

[0085] Step S121: judging whether the dynamic identifier corresponding to the memory variable exists, wherein the memory variable is configured to update the dynamic identifier according to the memory registered on the display device, and the memory corresponding to the dynamic identifier is the memory registered on the display device at the latest time.

[0086] In some embodiments, the display device is provided with a memory variable, which can be configured to take the value of the dynamic identifier. If there is no memory registered on the display device, the dynamic identifier is empty. If the user registers a memory, such as disk A, on the display device, the memory variable obtains the identifier of the memory, such as the UUID (Universally Unique Identifier) of disk A, and sets the dynamic identifier as the identifier of the memory, i.e., the value of the memory variable is equal to the ID of disk A. If the user registers a new memory, such as disk B, on the display device, the dynamic identifier is set as the identifier of the memory, i.e., the value of the memory variable is equal to the UUID of disk B. At this time, the memory variable only includes the identifier of disk B and does not include the identifier of memory A. According to the above configuration, the memory variable can be empty or include the identifier of the memory registered on the display device at the latest time.

[0087] In some embodiments, the memory variable can also not actively obtain the identifier of the memory registered on the display device. The controller of the display device updates the dynamic identifier in the memory variable as the identifier of the memory registered at the latest time after registering the memory.

[0088] In some embodiments, the memory variable can be stored in a preset path in the controller of the display device.

[0089] Step S122: if the dynamic identifier corresponding to the memory variable exists, judging whether the memory corresponding to the dynamic identifier is included in the connected memory according to the dynamic identifier.

[0090] In some embodiments, if one or more memories are registered on the display device, the value of the memory variable is the identifier of the memory registered on the display device at the latest time. The controller of the display device obtains the identifier of the memory registered on the display device at the latest time by obtaining the value of the memory variable.

[0091] In some embodiments, the connected storage can be one or more, and can or can not include the storage newly registered on the display device. The controller of the display device can compare the identification of the connected storage with the value of the storage variable, and if they are consistent, it is determined that the storage newly registered on the display device is included in the connected storage, and if they are inconsistent, it is determined that the storage newly registered on the display device is not included in the connected storage.

[0092] Step S123: If the storage corresponding to the dynamic identification is included in the connected storage, the storage corresponding to the dynamic identification is set as the target storage.

[0093] In some embodiments, if the storage corresponding to the dynamic identification is included in the connected storage, the storage path of the video recording program is set as the path of the storage corresponding to the dynamic identification on the display device, so that the storage corresponding to the dynamic identification becomes the target storage of the video recording program.

[0094] Step S124: If the storage corresponding to the dynamic identification is not included in the connected storage, the storage registration data on the display device is queried.

[0095] In some embodiments, the display device can also store storage registration data, which can be stored in the form of a storage registration record table. The controller of the display device can record the registration time and the storage identification of each storage registered on the display device in the storage registration record table.

[0096] In some embodiments, the display device can set a user operation record file, and the controller of the display device can record some operations of the user on the display device in the file, wherein the user operations include the registration of the storage.

[0097] In some embodiments, in response to the video recording request, the controller of the display device can query the storage variable under the preset path, and after obtaining that the value of the storage variable is empty, it can query the storage registration record table to obtain the identification and the registration time of the storage registered on the display device.

[0098] In some embodiments, in response to the video recording request, the controller of the display device can query the storage variable under the preset path, and after obtaining that the value of the storage variable is empty, it can query the user operation record file to obtain the identification and the registration time of the storage registered on the display device.

[0099] Step S125: According to the storage registration data, the storage with the latest registration time in the connected storage is obtained, and the storage with the latest registration time in the connected storage is set as the target storage.

[0100] In some embodiments, the display device can match the identity of the connected storage with the identity of the storage in the storage registration record list, obtain the registration time of the connected storage, compare the registration times of the plurality of connected storages, and set the storage with the latest registration time as the target storage.

[0101] In some embodiments, the display device can match the identity of the connected storage with the identity of the storage in the user operation record file, obtain the registration time of the connected storage, compare the registration times of the plurality of connected storages, and set the storage with the latest registration time as the target storage.

[0102] Step S126: In response to the video recording request, the connected storage is registered according to the absence of the dynamic identity corresponding to the storage variable, wherein the storage variable is configured to update the dynamic identity according to the storage registered on the display device, and the storage corresponding to the dynamic identity is the storage with the latest registration time on the display device.

[0103] In some embodiments, if the value of the storage variable is empty, the dynamic identity is absent, indicating that no storage has been registered on the display device. At this time, the registration interface can be entered, and the user can register the connected storage in the registration interface.

[0104] In some embodiments, if the number of connected storages of the display device is one, the storage can be directly registered; in some embodiments, if the number of connected storages of the display device is a plurality, the registration interface can be entered, and the user can select one of the storages to register in the registration interface, for example, select the storage inserted into the display device the latest to register.

[0105] In some embodiments, the disk registration interface on the display device can refer to Figure 7 As shown in Figure 7 , the disk registration interface can display a peripheral list, Figure 7 In the peripheral list, the name of one storage is displayed, indicating that the number of connected storages of the display device at this time is one. Exemplarily, the name of the storage is “HISENSE”.

[0106] In some embodiments, when the peripheral list has only the name of one storage, the user can press the confirmation key on the remote controller to input a disk registration instruction to the display device. The display device registers the storage in response to the disk registration instruction.

[0107] In some embodiments, the display device can detect the memory parameters of the memory, such as the capacity control, storage speed, etc. of the memory when registering the memory. The last detected memory parameter can be the storage speed. See Figure 8 After the storage speed detection is completed, the storage speed detection interface can display the storage speed of the memory and a "complete" control. The user can click the "complete" control in Figure 8 to exit the storage speed detection interface.

[0108] Step S127: Set the registered memory as the target storage memory.

[0109] In some embodiments, after the registered memory is obtained according to step S126, the display device can set the registered memory as the target storage memory of the video recording program.

[0110] Step S130: Start video recording and store the recorded video to the target storage memory.

[0111] In some embodiments, the video recording program can be configured to start video recording and store the recorded video to the target storage memory after determining the target storage memory.

[0112] In some embodiments, the video recording program supports instant recording mode and scheduled recording mode. At this time, the method of starting video recording can refer to Figure 9 , including steps S131-S135.

[0113] Step S131: Display an instant recording control and a scheduled recording control.

[0114] In some embodiments, the display device can generate and display a recording mode selection interface after determining the target storage memory. The recording mode selection interface can display an instant recording control and a scheduled recording control. The instant recording control can be configured to start video recording in response to a trigger. The scheduled recording control can be configured to generate and display a scheduled recording setting interface in response to a trigger.

[0115] Step S132: Receive the trigger instruction of the instant recording control or the trigger instruction of the scheduled recording control input by the user.

[0116] In some embodiments, the user can click the instant recording control in the recording mode selection interface to input the trigger instruction of the instant recording control to the display device.

[0117] Step S133: Start video recording in response to the trigger instruction of the instant recording control.

[0118] In some embodiments, the user can click the instant recording control in the recording mode selection interface to input a trigger instruction of the instant recording control to the display device.

[0119] Step S134: In response to the trigger instruction of the scheduled recording control, a scheduled recording interface is displayed.

[0120] In some embodiments, the user can click the scheduled recording control in the recording mode selection interface to input a trigger instruction of the scheduled recording control to the display device. The display device can generate and display a setting interface of the scheduled recording in response to the trigger instruction of the scheduled recording control.

[0121] Step S135: A scheduled time input in the scheduled recording interface is received, and video recording is started according to the scheduled time.

[0122] In some embodiments, the setting interface of the scheduled recording can refer to Figure 10 As shown in Figure 10 , in the scheduled recording interface, the user can input a scheduled time, which can include a start time and an end time of video recording. The user can click a “save” control in the scheduled recording interface to complete the setting of the scheduled time.

[0123] In some embodiments, after the user clicks the “save” control in the scheduled recording interface, the display device can record the scheduled time input by the user, and video recording is performed at the scheduled time.

[0124] In some embodiments, the recording interface after the display device starts video recording can refer to Figure 11 , which is a schematic diagram of a video recording interface according to some embodiments. As shown in Figure 11 , the video recording interface can display a recording progress menu, which can display a recording duration and a total recording duration. The total recording duration can be obtained by subtracting the start time of recording from the end time of recording input by the user.

[0125] In some embodiments, the display device can be configured to close the video recording program after the video recording is completed.

[0126] In some embodiments, the display device can be configured to enter a recording file list interface after the video recording is completed.

[0127] In some embodiments, the display device can be configured to display a recording file list control in response to a user input instruction to open the video recording program. The recording file list control can be configured to generate a recording file list request in response to a trigger. The display device can display a recording file list in response to the recording file list request.

[0128] In some embodiments, the method of the display device to display a recording file can refer toFigure 12 comprises steps S210-S230.

[0129] Step S210: receiving a recording file list request inputted by a user.

[0130] In some embodiments, the user can input the recording file list request to the display device by clicking the recording file list control.

[0131] Step S220: in response to the recording file list request, setting the storage with the latest registration time among the connected storages as a target storage.

[0132] In some embodiments, after receiving the recording file list request, the display device needs to select a storage from the connected storages as a target storage to show the recording files in the target storage. The method for the display device to determine the target storage can refer to Figure 6 , which will not be described herein again.

[0133] Step S230: obtaining and showing the recording files of the target storage.

[0134] In some embodiments, the recording files recorded by the video recording program can be in a fixed storage format, and after determining the target storage, the display device can search for the files in the fixed storage format in the target storage, and show the recording file list according to the searched recording files.

[0135] In some embodiments, the recording files recorded by the video recording program can be stored in a preset storage path, and after determining the target storage, the display device can search for the recording files in the preset storage path, and show the recording file list according to the searched recording files.

[0136] In some embodiments, after the user makes a video recording reservation through the video recording program, the video recording program can store the video recording reservation record.

[0137] In some embodiments, the recording file interface can refer to Figure 13 , as shown in Figure 13 , the recording file interface can display a recorded control and a reserved control. After obtaining the recording files and the video recording reservation record, the display device can generate the recording file interface, and the user can click the recorded control to view the recording files and click the reserved control to view the reservation record.

[0138] In some embodiments, when the display device displays the recording file interface, if a user inserts a memory into the display device, the display device can respond to the memory insertion instruction to determine whether the inserted memory is the memory corresponding to the dynamic identifier; if the inserted memory is the memory corresponding to the dynamic identifier, the display device refreshes the display to display the recording files of the memory corresponding to the dynamic identifier. If the inserted memory is not the memory corresponding to the dynamic identifier, the display device controls the display to continue to display the recording files of the target memory.

[0139] In some embodiments, when the display device displays the recording file interface, if a user inserts a memory into the display device, the display device can respond to the memory insertion instruction to determine whether the inserted memory is the memory corresponding to the dynamic identifier; if the inserted memory is the memory corresponding to the dynamic identifier, the display device refreshes the display to display the recording files of the memory corresponding to the dynamic identifier. If the inserted memory is not the memory corresponding to the dynamic identifier, the display device controls the display to continue to display the recording files of the target memory.

[0140] As can be seen from the above embodiments, the embodiments of the present application store the identifier of the latest registered memory on the display device, and when recording a video or displaying a recording file, the latest registered memory is selected from the memories connected to the display device, and the memory is used as the target memory for storing or displaying a video file. Since users usually prefer to select a newly registered disk for video recording, the present application is more in line with the actual needs of users compared with directly selecting the first memory connected to the display device as the target memory, and the user experience is improved.

[0141] In some embodiments, the display device can support multiple sources, such as a live source and an on-demand source, wherein the live source can include a broadcast television source, and the on-demand source can include an Internet of Things source. A user can switch sources through a remote control to watch programs of different sources. When the user starts a video recording program under a source, if the source is switched, the video recording program will be converted from a foreground program to a background program. When the user watches the program of the switched source, the user can forget to close the video recording program in time, which can cause the video recording program to continuously record and occupy a large amount of storage space.

[0142] To solve the above technical problems, the embodiments of the present application provide a video recording method, which is described below with reference to Figure 14 The method can include the following steps:

[0143] Step S1410: In response to receiving a video recording request input by a user under a first source, a video recording process is started.

[0144] In some embodiments, the first source can be a live source. When the source of the display device is a live source, the user can input a video recording request to the display device through the remote controller.

[0145] In some embodiments, a screen recording button can be provided on the remote controller of the display device, and a trigger signal of the screen recording button can be a video recording request. In some embodiments, a menu button can be provided on the remote controller of the display device, and the user can press the menu button to call up a menu containing a screen recording control on the display device, and a trigger signal of the screen recording control can be a video recording request.

[0146] In some embodiments, the display device generates a video recording request in response to a trigger signal of the screen recording button or a trigger signal of the screen recording control, and starts a video recording program according to the video recording request.

[0147] In some embodiments, the video recording program on the display device only supports one recording mode, such as instant recording. After the video recording program is started, a video recording process can be started to begin video recording.

[0148] In some embodiments, the video recording program on the display device can support instant recording and scheduled recording. When the video recording program supports instant recording and scheduled recording, the method for starting the video recording process can refer to Figure 15 , including steps S1511-S1513.

[0149] Step S1511: receiving a recording mode request input by the user under the first source.

[0150] In some embodiments, after the video recording program is started, the video recording process can display an instant recording control and a scheduled recording control. The instant recording control can be configured to generate a scheduled recording request in response to a trigger. The scheduled recording control can be configured to pop up a setting interface of scheduled recording in response to a trigger. The user can select or input a start time of recording and an end time of recording in the setting interface of scheduled recording, generate a scheduled recording request containing the start time of recording and the end time of recording, and in some embodiments, the user can also input a recording duration in the setting interface of scheduled recording without inputting the end time of recording. The scheduled recording request and the instant recording request both belong to the recording mode request.

[0151] Step S1512: determining whether the recording mode request is an instant recording request or a scheduled recording request.

[0152] In some embodiments, after receiving the recording mode request inputted by the user, the video recording program can determine whether the video recording request is an instant recording request or a scheduled recording request, for example, according to whether any one or more of the start time of the recording, the end time of the recording and the recording duration is included in the recording mode request, to determine that the recording mode request is an instant recording request, or according to whether the start time of the recording and the end time of the recording are included in the recording mode request, to determine that the recording mode request is a scheduled recording request.

[0153] Step S1513: If the recording mode request is an instant recording request, start the video recording process.

[0154] Step S1514: If the recording mode request is a scheduled recording request, determine whether the current time is the start time of the recording in the scheduled recording request.

[0155] Step S1515: If the current time is the start time of the recording, start the video recording process.

[0156] In some embodiments, if the current time is the start time of the recording, start the video recording process, and if the current time is not the start time of the recording, do not start the video recording process and return to step S1514.

[0157] Step S1420: After starting the video recording program under the first source, monitor the recording duration in real time.

[0158] In some embodiments, the display device can start a pre-set monitoring process according to the start of the video recording program, and in some embodiments, the monitoring process can also be configured to be started by the video recording program. In some embodiments, the monitoring process can be a system-level process.

[0159] In some embodiments, the video recording process starts timing after being started, and the timing time is the recording duration. The video recording process can report the recording duration to the monitoring process, so that the monitoring process can obtain the recording duration of the video recording process in real time.

[0160] In some embodiments, the monitoring process can also actively monitor the state of the video recording process. The state of the video recording process can include active and inactive, wherein the video recording process is active when the video recording process is in progress, and the video recording process is inactive when the video recording process is paused or ended. The monitoring process can obtain the recording duration of the video recording process according to the cumulative time of the active state of the video recording process.

[0161] In some embodiments, the video recording process can generate a recording progress menu. The recording progress menu is configured to display a recording duration that is updated in real time and a recording stop control configured to end the video recording program from recording in response to being triggered.

[0162] In some embodiments, the recording progress menu can be configured to be displayed superimposed on a recording interface of the video recording program. When the current source of the display device is the first source recorded by the video recording program, if the video recording program is the foreground program of the display device, the display device can display the recording interface on which the user can see the recording progress menu. When the user presses the stop button on the remote controller, the recording stop control can be triggered to end the video recording program from recording. When the current source of the display device is not the first source recorded by the video recording program, for example, the user switches the source to a second source, the video recording program is no longer the foreground program of the display device, and the display device does not display the recording interface of the video recording program, so the user cannot see the recording progress menu.

[0163] Step S1430: generating a recording status control with foreground display authority under all sources, wherein the recording status control is configured to display the recording duration.

[0164] In some embodiments, the monitoring process can generate a recording status control according to the recording duration, wherein the recording status control can be configured to display the recording duration.

[0165] In some embodiments, the recording status control is generated by a system-level program or process, such as the monitoring process, so as to have foreground display authority under all sources and can still be displayed in the foreground after the display device switches the source. For example, the recording status control can be generated by the display device master process after the video recording program is started or by the monitoring process of the display device after the video recording program is started, and can be configured to be displayed as a floating window on the current display interface of the display device. When the current source of the display device is the first source recorded by the video recording program, if the video recording program is the foreground program of the display device, the display device can display the recording interface on which the user can see the recording status control. When the current source of the display device is not the first source recorded by the video recording program, for example, the user switches the source to a second source, the video recording program is no longer the foreground program of the display device, and the display device does not display the recording interface of the video recording program, but can continue to display the recording status control as a floating window so that the user can see the recording status control.

[0166] Step S1440: in response to receiving a source switching request input by the user, switching the first source to a second source obtained according to the source switching request and controlling the video recording process to run in the background.

[0167] In some embodiments, after the user starts the video recording program under the first source, the user can press the source button on the remote controller to switch the source of the display device. In some embodiments, after the user starts the video recording program under the first source, the user can press the menu button on the remote controller to call up a menu containing a source switching control on the display device, and the trigger signal of the source switching control can be a source switching request.

[0168] In some embodiments, the display device generates a source switching request in response to the trigger signal of the source button or the trigger signal of the source switching control, and the source switching request can contain the source identifier of the source to be switched, such as the source identifier of the second source. The display device switches the first source to the second source according to the source switching request, where the second source can be an on-demand source.

[0169] In some embodiments, after the display device switches the first source to the second source, the video recording process can be controlled to run in the background, so that the video recording program becomes a background program, and the video recording process can continue to record. At this time, the foreground program is an application under the second source, such as a video on-demand program.

[0170] In some embodiments, the display device monitors the recording duration and state of the video recording process after the video recording program is converted into a background program, so as to update the recording state control.

[0171] Step S1450: Display the recording state control on the display interface under the second source.

[0172] In some embodiments, after the display device switches to the second source, the recording state control can be displayed in the form of a floating window on the display interface under the second source, so that the user can see the recording state control on the display device. The recording duration displayed by the recording state control can prompt the user that the program of the first source is being recorded, thereby solving the problem that the user cannot obtain video recording information after switching the source.

[0173] In some embodiments, the recording state control can be configured to be adjustable in position. The user can select the recording state control by pressing the screen recording button on the remote controller, and then move the recording state control to a suitable position by pressing the direction keys on the remote controller, for example, to the upper part, side part, or bottom part of the display area of the display device. In some embodiments, the size of the recording state control can also be configured to be adjustable.

[0174] As can be seen, by mounting the recording state control to the system-level program or process, the recording state control can still be displayed on the current interface of the display device when the source switching causes the video recording program to lose the right to display in the foreground, so that the user can check the recording progress at any time.

[0175] In some embodiments, after the user views the recording progress of the first source through the recording status control under the second source, if the user wants to end the recording, the user can press the source case on the remote controller to switch the source of the display device back to the first source, so that the video recording program is converted into the foreground program of the display device, the display device displays the recording interface of the video recording program, and the recording progress menu can be displayed on the recording interface. The user can trigger the recording stop control in the recording progress menu to stop the video recording of the video recording program.

[0176] In some embodiments, if the user wants to end the recording under the second source, the user can press the screen recording button, and the display device ends the video recording process under the first source according to the trigger instruction of receiving the screen recording button. The video recording process can be configured to automatically save the recorded video when the process is stopped.

[0177] To further describe the video recording method on the display device, Figure 16- Figure 19 Some interface schematic diagrams of the display device are shown. Figure 16- Figure 19 The interface shown does not show the display content of the first source or the second source, and only exemplary descriptions are made for the display of some controls or menus.

[0178] Referring to Figure 16 , a schematic diagram of a recording reservation setting interface according to some embodiments is shown, as Figure 16 shown, in some embodiments, the recording reservation setting interface can be provided with a recording mode control, a start time control, an end time control, a frequency control, a save control, and a cancel control. The recording mode control is configured to pop up a time option control and a manual stop option control in response to triggering. The time option control is configured to end the recording at the end time of the recording input by the user in response to triggering. The manual stop is configured to continue recording until the user triggers the recording stop control in the recording progress menu to end the recording in response to triggering. The frequency control is configured to pop up a frequency option control such as a once only option control, a daily option control, a Monday option control, a Tuesday option control, a Wednesday option control, a Thursday option control, and a Friday option control in response to triggering. The frequency option control can start recording at a specific time in response to triggering.

[0179] Referring to Figure 17 , a schematic diagram of a recording interface according to some embodiments is shown, as Figure 17 shown, in some embodiments, the recording interface can display a recording progress menu, and the recording progress menu can display the recording duration and the total recording duration. The total recording duration can be obtained by subtracting the start time of the recording from the end time of the recording input by the user.

[0180] In some embodiments, the recording progress menu can be configured to automatically close after displaying a second preset time, wherein the second preset time can be 10 seconds.

[0181] In some embodiments, when the current display interface of the display device is the recording interface, the user can press the return button on the remote control, and the display device will close the recording progress menu in response to receiving the trigger command from the return button.

[0182] In some embodiments, after the main process or monitoring process of the display device detects that the recording progress menu is closed, it can display the recording status control floating on the display interface below the first information source, such as... Figure 18 As shown.

[0183] See Figure 18 This is a schematic diagram of a recording interface according to some embodiments, such as Figure 18 As shown, during recording, when the display device does not show the recording progress menu, a recording status control can be displayed. In some embodiments, the recording status control can display the recording duration. Figure 18 In the text, the recording duration is 00:00:30, which means that 30 seconds have been recorded.

[0184] In some embodiments, under the first signal source, when the user switches the signal source, the display device can... Figure 17 The recording progress menu shown has been switched to Figure 18 The recording status controls shown, namely the recording status controls under the first signal source and the recording status controls under the second signal source, can both have the following appearances: Figure 18 The appearance shown is a small dot indicating the recording duration.

[0185] In some embodiments, the main process or monitoring process of the display device may reduce the transparency of the recording status control after a first preset time has elapsed, such as... Figure 19 As shown, it can be seen that, with Figure 18 In comparison, the transparency of the recording status control is reduced, and the first preset time can be 5 seconds.

[0186] In some embodiments, under the first source, the recording progress menu can be displayed. Figure 17 After the second preset time shown in the recording progress menu, by Figure 17 Convert to Figure 18 The recording status control shown can be set to open after a first preset time. Figure 18 Convert to Figure 19 The appearance shown; when the first signal source is switched to the second signal source, if the interface displayed before the switch is as shown. Figure 17 The recording progress menu shown will be displayed after switching. Figure 18If the recording state control is displayed before the switching, the interface displays Figure 18 If the recording state control is displayed before the switching, the interface displays Figure 18 If the recording state control is displayed before the switching, the interface displays Figure 19 If the recording state control is displayed before the switching, the interface displays Figure 18 If the recording state control is displayed before the switching, the interface displays Figure 18 If the recording state control is displayed before the switching, the interface displays Figure 18 If the recording state control is displayed before the switching, the interface displays Figure 19 If the recording state control is displayed before the switching, the interface displays

[0187] If the recording state control is displayed before the switching, the interface displays Figure 19 The transparency of the recording state control can be reduced to reduce the visual interference with the display content of the display device. In some embodiments, the transparency of the recording state control can be configured to be reduced to 50%, and can also be configured to be reduced to other values.

[0188] In some embodiments, under the first source, when the user presses the screen recording button on the remote controller to start the video recording program, the recording mode can be selected; when the user selects the scheduled recording, the setting interface of the scheduled recording as shown in Figure 16 can be entered; the user can set the scheduled recording time in the setting interface as shown in Figure 16 ; when the start time of the recording is reached, the recording interface as shown in Figure 17 can be entered; the user can press the back button on the remote controller to enter the recording interface as shown in Figure 18 , or after an interval of 10 seconds, Figure 17 the interface as shown in Figure 18 can be automatically switched to; after an interval of 5 seconds, Figure 18 the interface as shown in Figure 19 can be automatically switched to. When the user presses the screen recording button or the confirm button on the remote controller, the interface as shown in Figure 19 can be entered. Figure 17 In some embodiments, under the first source, when the current display interface is any one of the interfaces in

[0189] , the user switches the source of the display device to enter the interface as shown in Figure 17- Figure 19 , at this time, the source of the display device has been switched to the second source; after an interval of 5 seconds, Figure 18 the interface as shown in Figure 19 can be automatically switched to; if the user needs to end the recording, the display device can be switched from the second source to the first source to enter the interface as shown in Figure 19 , and the recording stop control is triggered to end the recording. Figure 17

[0190] ​As can be seen from the above embodiments, the embodiments of the present application generate a recording state control with foreground display permission of all sources after starting the video recording process, so that the user can see the recording state control on the display interface of the switched source after switching the source, solve the problem of unable to view the recording information after switching the source, avoid the continuous recording to occupy a large amount of storage space of the disk, and improve the user's video recording experience; the recording information is displayed through the recording state control, and the influence on the user's viewing effect after switching the source is small.
