[0065] In some embodiments, the user may input a user command through a graphical user interface (GUI) displayed on the display 275, and the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user may input a user command by inputting a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through a sensor.

[0066] In some embodiments, "user interface" is a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an interface element such as an icon, window, or control displayed on a display screen of an electronic device, wherein a control may include at least one of icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, and other visual interface elements.

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

[0068] In some embodiments, the system of the display device may include a kernel, a command parser (shell), a file system, and an application. The kernel, shell, and file system together constitute the basic operating system structure, which allows users to manage files, run programs, and use the system. After power-on, the kernel starts, activates the kernel space, abstracts hardware, initializes hardware parameters, etc., runs and maintains virtual memory, schedulers, signals, and inter-process communication (IPC). After the kernel starts, the shell and user applications are loaded. After startup, the application is compiled into machine code to form a process.

[0069] See also Figure 4 In some embodiments, the system is divided into four layers, from top to bottom, namely, the application layer (Applications) layer (referred to as "application layer"), the application framework layer (Application Framework) layer (referred to as "framework layer"), the Android runtime (Android runtime) and system library layer (referred to as "system runtime library layer"), and the kernel layer.

[0070] In some embodiments, at least one application is running in the application layer, and these applications can be window programs, system settings programs, clock programs, etc. provided by the operating system, or applications developed by third-party developers. In specific implementations, the application packages in the application layer are 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 predefined functions. The application framework layer is equivalent to a processing center that determines the actions that applications in the application layer take. Through the API interface, applications can access system resources and obtain system services during execution.

[0072] like Figure 4 As shown, in the embodiment of the present application, the application framework layer includes managers, content providers, etc., wherein the manager includes at least one of the following modules: activity manager

[0073] (Activity Manager) is used to interact with all activities running in the system; the Location Manager is used to provide system services or applications with access to the system location service; the Package Manager is used to retrieve various information related to the application package currently installed on the device; the Notification Manager is used to control the display and clearing of notification messages; the Window Manager is used to manage icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0074] In some embodiments, the activity manager is used to manage the life cycle of each application and the common navigation back function, such as controlling the exit, opening, and back of the application. The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, capturing the screen, and controlling the display window changes (for example, reducing the display window, shaking the display, distorting the display, etc.).

[0075] In some embodiments, the system runtime layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system will run the C / C++ library contained in the system runtime layer to implement the functions to be implemented by the framework layer.

[0076] In some embodiments, the kernel layer is a layer between hardware and software. Figure 4 As shown, the kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0077] The hardware or software architecture in some embodiments may be based on the introduction in the above embodiments, and in some embodiments may be based on other similar hardware or software architectures, so as to implement the technical solution of the present application.

[0078] In some embodiments, a video recording program may be installed on the display device to implement the video recording function. The video recording program may be a PVR (Personal video recorder) program, which can implement the PVR recording function. In order to prevent video files from occupying a large amount of storage space of the display device, the PVR program may store the recorded video files in a memory connected to the display device, wherein the memory may be a disk or other storage device. The present application takes the disk as an example for introduction. When the display device uses a new disk to store recorded files, it is necessary to register the disk to check whether the performance of the disk meets the requirements for storing recorded files. In some embodiments, the user may have multiple disks to store recorded files. 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 often not the disk that the user wants to use.

[0079] In order to solve the above technical problems, the embodiment of the present application provides a video recording method according to the need to register a memory when the display device is recording a video. Figure 5 , the method may include the following steps:

[0080] Step S110: receiving a video recording request input by a user.

[0081] In some embodiments, the video recording request may be a request generated by an instruction to start a video recording program. A user inputs an instruction to start a PVR recording program on a display device, and the display device may generate a video recording request according to the instruction to start the PVR recording program.

[0082] Step S120: In response to the video recording request, the storage device with the latest registration time among the connected storage devices is set as the target storage device.

[0083] In some embodiments, the display device is already connected to a storage device before receiving the video recording request. In this case, the display device can directly use the storage device as the target storage device for video recording.

[0084] In some embodiments, before receiving the video recording request, the display device has been connected to multiple storage devices. At this time, the display device can select a storage device as the target storage device for video recording.

[0085] In some embodiments, to optimize the user experience, the method for setting the target memory of the display device can be found in Figure 6 , including steps S121-S127.

[0086] Step S121: Determine whether a dynamic identifier corresponding to a memory variable exists, wherein the memory variable is configured to update the dynamic identifier according to a memory registered on a display device, so that the memory corresponding to the dynamic identifier is the memory with the latest registration time on the display device.

[0087] In some embodiments, the display device is provided with a memory variable, and the memory variable can be configured as follows: the value is a dynamic identifier, and if no memory has been registered on the display device, the dynamic identifier is empty. If the user registers a memory on the display device, such as disk A, the memory variable obtains the identifier of the memory, such as the UUID (Universally Unique Identifier) ​​of disk A, and sets the dynamic identifier to the identifier of the memory, that is, the value of the memory variable is equal to the ID of disk A; if the user registers a new memory on the display device, such as disk B, the dynamic identifier is set to the identifier of the memory, that is, 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 with the latest registration time on the display device.

[0088] In some embodiments, the memory variable may not actively obtain the identifier of the memory registered on the display device. After registering the memory, the controller of the display device updates the dynamic identifier in the memory variable to the identifier of the latest registered memory.

[0089] In some embodiments, the memory variables may be stored under a preset path within the controller of the display device.

[0090] Step S122: If the dynamic identifier corresponding to the memory variable exists, determine whether the connected memory includes the memory corresponding to the dynamic identifier according to the dynamic identifier.

[0091] 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 most recently registered on the display device. The controller of the display device obtains the identifier of the memory most recently registered on the display device by acquiring the value of the memory variable.

[0092] In some embodiments, the connected memory may be one or more, and may include the latest registered memory on the display device, or may not include the latest registered memory on the display device. The controller of the display device may compare the identifier of the connected memory with the value of the memory variable. If they are consistent, it is determined that the connected memory includes the latest registered memory on the display device. If they are inconsistent, it is determined that the connected memory does not include the latest registered memory on the display device.

[0093] Step S123: If the connected storage includes the storage corresponding to the dynamic identifier, the storage corresponding to the dynamic identifier is set as the target storage.

[0094] In some embodiments, if the connected storage includes the storage corresponding to the dynamic identifier, the storage path of the video recording program is set to the path of the storage corresponding to the dynamic identifier on the display device, so that the storage corresponding to the dynamic identifier becomes the target storage of the video recording program.

[0095] Step S124: If the connected storage does not include the storage corresponding to the dynamic identifier, query the storage registration data on the display device.

[0096] In some embodiments, the display device may also store memory registration data, which may be stored in the form of a memory registration record table. Each time a memory is registered on the display device, the controller of the display device may record the registration time and memory identifier of the memory in the memory record table.

[0097] In some embodiments, the display device may be provided with a user operation record file, and the controller of the display device may record some operations of the user on the display device in the file, wherein the user operations include the registration of the memory.

[0098] In some embodiments, the controller of the display device can query the memory variable under a preset path in response to a video recording request. After obtaining that the value of the memory variable is empty, it can search the memory registration record table to obtain the identifier and registration time of the memory registered on the display device.

[0099] In some embodiments, the controller of the display device can query the memory variable under a preset path in response to a video recording request. After obtaining that the value of the memory variable is empty, it can search the user operation record file to obtain the identifier and registration time of the memory registered on the display device.

[0100] Step S125: obtaining the memory with the latest registration time among the connected memories according to the memory registration data, and setting the memory with the latest registration time among the connected memories as the target memory.

[0101] In some embodiments, the display device may match the identifier of the connected memory with the identifier of the memory in the memory registration record table to obtain the registration time of the connected memory, compare the registration times of multiple connected memories, and set the memory with the latest registration time as the target memory.

[0102] In some embodiments, the display device may match the identifier of the connected storage with the identifier of the storage in the user operation record file to obtain the registration time of the connected storage, compare the registration times of multiple connected storages, and set the storage with the latest registration time as the target storage.

[0103] Step S126: In response to the video recording request, according to the absence of the dynamic identifier corresponding to the memory variable, the connected memory is registered, wherein the memory variable is configured to update the dynamic identifier according to the memory registered on the display device, so that the memory corresponding to the dynamic identifier is the memory with the latest registration time on the display device.

[0104] In some embodiments, if the value of the memory variable is empty, the dynamic identifier does not exist, indicating that no memory has been registered on the display device. At this time, a registration interface can be entered, and the user can register the connected memory on the registration interface.

[0105] In some embodiments, if the display device is connected to one storage device, the storage device can be directly registered; in some embodiments, if the display device is connected to multiple storage devices, a registration interface can be entered, and the user can select one of the storage devices to register on the registration interface, for example, select the storage device most recently inserted into the display device for registration.

[0106] In some embodiments, the disk registration interface on the display device can be seen in Figure 7 ,like Figure 7 As shown, the disk registration interface can display a list of peripherals. Figure 7 In the peripheral list, a storage name is displayed, indicating that the number of storages connected to the display device at this time is one. For example, the name of the storage is "HISENSE".

[0107] In some embodiments, when the peripheral list contains only one memory name, the user can press the confirmation key on the remote control to input a disk registration instruction to the display device, and the display device registers the memory in response to the disk registration instruction.

[0108] In some embodiments, when registering a memory, the display device may detect memory parameters that affect video recording, such as the memory capacity control and the storage speed. The last memory parameter detected may be the storage speed. Figure 8 After the storage speed test is completed, the storage speed test interface can display the storage speed of the storage device and the "Complete" control. Figure 8 Click the "Finish" control to exit the storage speed detection interface.

[0109] Step S127: Set the registered memory as the target memory.

[0110] In some embodiments, after obtaining the registered memory according to step S126, the display device may set the registered memory as the target memory of the video recording program.

[0111] Step S130: Start video recording, and store the recorded video in the target storage.

[0112] In some embodiments, the video recording program may be configured to start video recording after determining the target storage, and store the recorded video in the target storage.

[0113] In some embodiments, the video recording program supports an instant recording mode and a scheduled recording mode. In this case, the method of starting video recording can be found in Fig. 9 , including steps S131-S135.

[0114] Step S131: Displaying an instant recording control and a scheduled recording control.

[0115] In some embodiments, after determining the target storage device, the display device may generate and display a recording mode selection interface, and the recording mode selection interface may display instant recording controls and scheduled recording controls, wherein the instant recording controls may be configured to start video recording in response to a trigger, and the scheduled recording controls may be configured to generate and display a setting interface for scheduled recording in response to a trigger.

[0116] Step S132: receiving a trigger instruction of the instant recording control or a trigger instruction of the scheduled recording control input by the user.

[0117] In some embodiments, the user can click on the instant recording control in the recording mode selection interface to input a trigger instruction of the instant recording control to the display device.

[0118] Step S133: In response to the trigger instruction of the instant recording control, start video recording.

[0119] In some embodiments, the user can click on the instant recording control in the recording mode selection interface to input a trigger instruction of the instant recording control to the display device.

[0120] Step S134: In response to the triggering instruction of the scheduled recording control, displaying the scheduled recording interface.

[0121] In some embodiments, the user can click the scheduled recording control on 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 for scheduled recording in response to the trigger instruction of the scheduled recording control.

[0122] Step S135: receiving the reservation time input in the reservation recording interface, and starting video recording according to the reservation time.

[0123] In some embodiments, the setting interface for scheduled recording can be found in Fig.10 ,like Fig.10 As shown, in the reservation recording interface, the user can enter the reservation time, which may include the start time and end time of the video recording. The user can click the "Save" control in the reservation recording interface to complete the setting of the reservation time.

[0124] In some embodiments, when the user clicks the "Save" control on the scheduled recording interface, the display device may record the scheduled time entered by the user and perform video recording at the scheduled time.

[0125] In some embodiments, the recording interface after the display device starts video recording can be seen in Fig.11 , is a schematic diagram of a video recording interface according to some embodiments, such as Fig.11 As shown, the video recording interface can display a recording progress menu, and the recording progress menu can display the recording time and the total recording time, wherein the total recording time can be obtained by subtracting the recording start time from the recording end time input by the user.

[0126] In some embodiments, the display device may be configured to close the video recording program after the video recording ends.

[0127] In some embodiments, the display device may be configured to enter a recording file list interface after the video recording ends.

[0128] In some embodiments, the display device may be configured to display a recording file list control in response to an instruction input by a user to open a video recording program. The recording file list control may be configured to generate a recording file list request in response to a trigger, and the display device may display a recording file list in response to the recording file list request.

[0129] In some embodiments, the method for displaying a recording file on a display device can be found in Fig.12 , including steps S210-S230.

[0130] Step S210: receiving a recording file list request input by a user.

[0131] In some embodiments, the user may input a recording file list request to the display device by clicking a recording file list control.

[0132] Step S220: In response to the recording file list request, the storage device with the latest registration time among the connected storage devices is set as the target storage device.

[0133] In some embodiments, after receiving a request for a list of recorded files, the display device needs to select a storage device from the connected storage devices as a target storage device and display the recorded files in the target storage device. Figure 6 , I will not go into details here.

[0134] Step S230: Acquire and display the recording file in the target storage.

[0135] In some embodiments, the recording files recorded by the video recording program may be in a fixed storage format. After determining the target storage, the display device may search for files in the storage format in the target storage and display a list of recording files based on the found recording files.

[0136] In some embodiments, the recording files recorded by the video recording program can be stored in a preset storage path. After determining the target storage, the display device can search for the recording files in the preset storage path and display a list of recording files based on the found recording files.

[0137] In some embodiments, after the user schedules video recording through the video recording program, the video recording program may store the scheduled record of the video recording.

[0138] In some embodiments, the recording file interface can be found in Fig.13 ,like Fig.13 As shown, the recording file interface can display recorded controls and scheduled controls. After the display device obtains the recording file and the scheduled record of the video recording, it can generate the recording file interface. The user can click the recorded control to view the recording file, and click the scheduled control to view the scheduled record.

[0139] In some embodiments, when the display device displays a recording file interface, if the user inserts a memory on the display device, the display device can respond to the memory insertion instruction and 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, refresh the display so that the display displays the recording file of the memory corresponding to the dynamic identifier. If the inserted memory is not the memory corresponding to the dynamic identifier, control the display to continue to display the recording file of the target memory.

[0140] In some embodiments, when the display device displays a recording file interface, if the user unplugs a storage device on the display device, the display device can respond to the storage device insertion instruction to determine whether the unplugged storage device is the target storage device; if the unplugged storage device is the target storage device, refresh the display so that the display displays the recording file of the connected storage device; if the unplugged storage device is not the target storage device, control the display to continue to display the recording file of the target storage device.

[0141] As can be seen from the above embodiments, the embodiments of the present application store the identifier of the storage device most recently registered on the display device. When recording a video or displaying a recorded file, the storage device with the latest registration time can be selected from the storage devices connected to the display device, and the storage device can be used as the target storage device for storing or displaying the video file. Since users usually prefer to select a newly registered disk for video recording, this application is more in line with the actual needs of users and improves the user experience compared to directly selecting the first storage device connected to the display device as the target storage device.

[0142] In some embodiments, the display device may support multiple sources, such as live sources and on-demand sources, where the live sources may include broadcast TV sources, and the on-demand sources may include IoT sources. Users can switch sources through a remote control to watch programs from different sources. After a user starts a video recording program under one source, if the source is switched, the video recording program will be converted from a foreground program to a background program. When watching programs from a switched source, the user may forget to close the video recording program in time, causing the video recording program to continue recording and occupy a large amount of storage space.

[0143] In order to solve the above technical problems, the present application provides a video recording method. Fig.14 , the method may include the following steps:

[0144] Step S1410: Under a first information source, in response to receiving a video recording request input by a user, starting a video recording process.

[0145] In some embodiments, the first information source may be a live broadcast information source. When the information source of the display device is a live broadcast information source, the user may input a video recording request to the display device through a remote controller.

[0146] In some embodiments, a screen recording button may be provided on the remote control of the display device, and the trigger signal of the screen recording button may be used to generate a video recording request; in some embodiments, a menu button may be provided on the remote control of the display device, and the user may press the menu button to bring up a menu containing a screen recording control on the display device, and the trigger signal of the screen recording control may be used to generate a video recording request.

[0147] In some embodiments, the display device generates a video recording request in response to a trigger signal of a screen recording button or a trigger signal of a screen recording control, and starts a video recording program according to the video recording request.

[0148] 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 start video recording.

[0149] In some embodiments, the video recording program on the display device may 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 be found in Fig.15 , including steps S1511-S1513.

[0150] Step S1511: receiving a recording mode request input by a user under a first information source.

[0151] In some embodiments, after the video recording program is started, the video recording process may display an instant recording control and a scheduled recording control. The instant recording control may be configured to generate a scheduled recording request in response to a trigger. The scheduled recording control may be configured to pop up a scheduled recording setting interface in response to a trigger. The user may select or enter the start time and end time of the recording in the scheduled recording setting interface to generate a scheduled recording request including the start time and end time of the recording. In some embodiments, the user may also enter the recording duration in the scheduled recording setting interface without entering the end time of the recording. Both the scheduled recording request and the instant recording request belong to the recording mode request.

[0152] Step S1512: Determine whether the recording mode request is an instant recording request or a scheduled recording request.

[0153] In some embodiments, after receiving a recording mode request input by a user, the video recording program can determine whether the video recording request is an instant recording request or a scheduled recording request. For example, based on the fact that the recording mode request does not contain any one or more of the recording start time, the recording end time, and the recording duration, the recording mode request is determined to be an instant recording request; based on the fact that the recording mode request contains the recording start time and the recording end time, the recording mode request is determined to be a scheduled recording request.

[0154] Step S1513: If the recording mode request is an instant recording request, start the video recording process.

[0155] 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.

[0156] Step S1515: If the current time is the start time of the recording, start the video recording process.

[0157] In some embodiments, if the current time is the start time of the recording, the video recording process is started; if the current time is not the start time of the recording, the video recording process is not started and the process returns to step S1514.

[0158] Step S1420: After starting the video recording program under the first signal source, the recording duration is monitored in real time.

[0159] In some embodiments, the display device can start a preset monitoring process according to the start of the video recording program. 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.

[0160] 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.

[0161] In some embodiments, the monitoring process may also actively monitor the status of the video recording process, and the status of the video recording process may include active and inactive, wherein when the video recording process is active, it indicates that the video recording process is recording the video, and when the video recording process is inactive, it indicates that the video recording process is paused or ends the video recording. The monitoring process may derive the recording duration of the video recording process based on the accumulated time that the video recording process is in the active state.

[0162] In some embodiments, the video recording process may generate a recording progress menu configured to display the recording duration and a recording stop control, wherein the recording duration is updated in real time, and the recording stop control is configured to cause the video recording program to end recording in response to a trigger.

[0163] In some embodiments, the recording progress menu may be configured to be displayed superimposed on the recording interface of the video recording program. When the current signal source of the display device is the first signal source recorded by the video recording program, if the video recording program is the foreground program of the display device, the display device may display the recording interface, and the user may see the recording progress menu on the recording interface. When the user presses the stop button on the remote control, the recording stop control may be triggered, so that the video recording program ends recording. When the current signal source of the display device is not the first signal source recorded by the video recording program, for example, when the user switches the signal source to the second signal source, the video recording program is no longer the foreground program of the display device, the display device does not display the recording interface of the video recording program, and the user cannot see the recording progress menu.

[0164] Step S1430: Generate a recording status control with foreground display permission for all signal sources, wherein the recording status control is configured to display the recording duration.

[0165] In some embodiments, the monitoring process may generate a recording status control according to the recording duration, wherein the recording status control may be configured to display the recording duration.

[0166] In some embodiments, the recording status control is generated by a system-level program or process, such as a monitoring process, so that it can have the foreground display permission under all signal sources, and can still be displayed in the foreground after the display device switches the signal source. For example, the recording status control is generated by the display device main process after the video recording program is started, or by the display device monitoring process after the video recording program is started. The recording status control can be configured to be displayed in a floating window on the current display interface of the display device. When the current signal source of the display device is the first signal 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, and the user can see the recording status control on the recording interface. When the current signal source of the display device is not the first signal source recorded by the video recording program, for example, when the user switches the signal source to the second signal 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 in a floating window so that the user can see the recording status control.

[0167] Step S1440: in response to receiving a signal source switching request input by a user, switching the first signal source to a second signal source obtained according to the signal source switching request, and controlling the video recording process to run in the background.

[0168] In some embodiments, after the user starts the video recording program under the first source, the user presses the source button on the remote control 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 presses the menu button on the remote control to call up a menu containing a source switching control on the display device, and the trigger signal of the source switching control may be to generate a source switching request.

[0169] In some embodiments, the display device generates a source switching request in response to a trigger signal of a source button or a trigger signal of a source switching control. The source switching request may include an identifier of a source to be switched, such as a source identifier of a second source. The display device switches the first source to a second source according to the source switching request, wherein the second source may be an on-demand source.

[0170] In some embodiments, after the display device switches the first signal source to the second signal source, it can control the video recording process to run in the background, making the video recording program a background program, and the video recording process can continue recording. At this time, the foreground program is an application under the second signal source, such as a video on demand program.

[0171] In some embodiments, after the video recording program of the display device is converted into a background program, the monitoring process can continue to monitor the recording duration and status of the video recording process, thereby updating the recording status control.

[0172] Step S1450: Displaying the recording status control on the display interface of the second information source.

[0173] In some embodiments, after switching to the second source, the display device may display the recording status control in the form of a floating window on the display interface under the second source, so that the user can see the recording status control on the display device. The recording time displayed by the recording status control can remind 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.

[0174] In some embodiments, the recording status control can be configured to be adjustable in position, and the user can select the recording status control by pressing the screen recording button on the remote control, and then press the direction keys on the remote control to move the recording status control to a suitable position, for example, to the top, side, or bottom of the display area of ​​the display device. In some embodiments, the size of the recording status control can also be configured to be adjustable.

[0175] It can be seen that this application mounts the recording status control setting to a system-level program or process. When the signal source is switched so that the video recording program does not have the permission to display in the foreground, the recording status control can still be displayed on the current interface of the display device, allowing the user to check the recording progress at any time.

[0176] In some embodiments, after the user views the recording progress of the first signal source through the recording status control under the second signal source, if the user wants to end the recording, the user can press the signal source case on the remote control to switch the signal source of the display device back to the first signal source, so that the video recording program is converted to the foreground program of the display device, and the display device displays the recording interface of the video recording program. A recording progress menu can be displayed on the recording interface, and the user can trigger the recording stop control in the recording progress menu to make the video recording program stop video recording.

[0177] In some embodiments, if the user wants to end recording under the second signal source, he can press the screen recording button. The display device ends the video recording process under the first signal source based on the trigger instruction received from the screen recording button. The video recording process can be configured to automatically save the recorded video when the process is stopped.

[0178] To further describe the video recording method on the display device, Figure 16-Figure 19 Shown are schematic diagrams of interfaces of some display devices. Figure 16-Figure 19 The interface shown does not show the display content of the first information source or the second information source, and only exemplifies the display of some controls or menus.

[0179] See also Fig.16 , is a schematic diagram of a setting interface for scheduled recording according to some embodiments, such as Fig.16 As shown, in some embodiments, the setting interface of the scheduled recording may 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, wherein the recording mode control is configured to pop up a time option control and a manual stop option control in response to a trigger, the time option control is configured to end the recording at the end time of the recording input by the user in response to a trigger, and the manual stop is configured to continue recording in response to a trigger until the user ends the recording when the recording stop control is triggered in the recording progress menu. 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 a trigger, and the frequency option control can start recording at a specific time in response to a trigger.

[0180] See also Fig.17 , is a schematic diagram of a recording interface according to some embodiments, such as Fig.17 As shown, in some embodiments, the recording interface may display a recording progress menu, which may display the recording duration and the total recording duration, wherein the total recording duration may be obtained by subtracting the recording start time from the recording end time input by the user.

[0181] In some embodiments, the recording progress menu may be configured to automatically close after being displayed for a second preset time, where the second preset time may be 10 seconds.

[0182] In some embodiments, when the current display interface of the display device is a recording interface, the user can press the return button on the remote control, and the display device closes the recording progress menu in response to receiving the trigger instruction of the return button.

[0183] In some embodiments, after the main process or monitoring process of the display device detects that the recording progress menu is closed, the recording status control may be suspended and displayed on the display interface under the first information source, such as Fig.18 shown.

[0184] See also Fig.18 , is a schematic diagram of a recording interface according to some embodiments, such as Fig.18 As shown, during the recording process, when the display device does not display the recording progress menu, the recording status control can be displayed. In some embodiments, the recording status control can display the recording duration. Fig.18 In the video, the recording duration is 00:00:30, which means the recorded duration is 30 seconds.

[0185] In some embodiments, under the first signal source, when the user switches the signal source, the display device may Fig.17 The recording progress menu shown switches to Fig.18 The appearance of the recording status control shown, that is, the recording status control under the first source and the recording status control under the second source, can be Fig.18 The appearance shown is a small dot and the recording time.

[0186] In some embodiments, the main process or monitoring process of the display device may reduce the transparency of the recording status control after the recording status control is displayed for a first preset time, such as Fig.19 As shown, visible, and Fig.18 In comparison, the transparency of the recording status control is reduced, wherein the first preset time may be 5 seconds.

[0187] In some embodiments, under the first source, the recording progress menu may be displayed Fig.17 After the second preset time in the recording progress menu, the Fig.17 Convert to Fig.18 The recording status control shown in the figure can be changed after the first preset time. Fig.18 Convert to Fig.19 The appearance shown; when the first signal source is switched to the second signal source, if the display interface before switching shows Fig.17 The recording progress menu shown in the figure is displayed after switching. Fig.18The recording status controls shown in the figure are as follows: Fig.18 The recording status control shown in the figure is displayed after switching. Fig.18 The recording status controls shown in the figure are as follows: Fig.19 The recording status control shown in the figure is displayed after switching. Fig.18 The recording status controls are shown in the figure. In the second source, the recording status controls can be Fig.18 After the first preset time, the recording status control shown by Fig.18 Convert to Fig.19 The appearance shown.

[0188] like Fig.19 As shown, after the transparency of the recording status control is reduced, the visual interference to the display content of the display device can be reduced. In some embodiments, the transparency of the recording status control can be configured to be reduced to 50%, and of course, it can also be configured to be reduced to other values.

[0189] In some embodiments, under the first signal source, when the user presses the screen recording button on the remote control to start the video recording program, the user can select a recording mode; when the user selects to schedule recording, the user can proceed as follows: Fig.16 The scheduled recording setting interface shown in the figure; the user Fig.16 The setting interface shown can be used to set the scheduled recording time; when the recording start time is reached, you can enter Fig.17 The recording interface shown in the figure; users can press the return button on the remote control to enter Fig.18 The recording interface shown, or after an interval of 10 seconds, Fig.17 Automatically switches to Fig.18 ; After another 5 seconds, Fig.18 Automatically switches to Fig.19 When the user presses the Record Screen button or the Confirm button on the remote control, Fig.19 Enter Fig.17 .

[0190] In some embodiments, under the first information source, the current display interface is Figure 17-Figure 19 When the user switches the source of the display device, he can enter Fig.18 The interface shown, at this time, the signal source of the display device has been switched to the second signal source; after an interval of 5 seconds, Fig.19 Automatically switches to Fig.19 If the user needs to end the recording, he can switch the display device from the second source to the first source and enter Fig.17 In the interface shown, trigger the recording stop control to end the recording.

[0191] It can be seen from the above embodiments that the embodiments of the present application generate a recording status control with foreground display permissions under all signal sources after starting the video recording process, so that after the user switches the signal source, the recording status control can be seen on the display interface of the switched signal source, thereby solving the problem of not being able to view the recording information after switching the signal source, avoiding continuous recording causing the recorded video to occupy a large amount of storage space on the disk, and improving the user's video recording experience; displaying the recording information through the recording status control has little impact on the user's viewing effect under the switched signal source.

[0192] Since the above embodiments are all described by citing and combining with other embodiments, different embodiments have the same parts, and the same and similar parts between the embodiments in this specification can be referred to each other. No further detailed description is given here.
