When a user starts a video recording program under an information source, if the information source is switched, the video recording program is converted from a foreground program to a background program. When watching the switched information source program, the user may forget to turn off the video recording program in time, so that the video recording program may be continuously recorded and occupy a large amount of storage space.

In order to solve the above technical problem, an embodiment of the present application provides a video recording method, and referring to fig. 6, the method may include the following steps:

step S110: and under the first information source, responding to the received video recording request input by the user, and starting a video recording process.

In some embodiments, the first source may be a live source. When the information source of the display equipment is a live information source, a user can input a video recording request to the display equipment through a remote controller.

In some embodiments, a remote controller of the display device may be provided with a screen recording key, and a trigger signal of the screen recording key may be to generate a video recording request; in some embodiments, a menu button may be disposed on a remote controller of the display device, and a user may call up a menu containing a screen recording control on the display device by pressing the menu button, and a trigger signal of the screen recording control may be a request for generating a video recording.

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.

In some embodiments, the video recording program on the display device only supports one recording mode, such as real-time recording, and after the video recording program is started, a video recording process can be started to start video recording.

In some embodiments, a video recording program on a display device may support both live and scheduled recordings. When the video recording program supports both the instant recording and the scheduled recording, the method for starting the video recording process can be seen in fig. 7, which includes steps S111-S113.

Step S111: under a first source, a user input recording mode request is received.

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, and the instant recording control may be configured to generate a scheduled recording request in response to a trigger. The scheduled recording control can be configured to pop up a scheduled recording setting interface in response to the trigger, and the user can select or input the recording starting time and the recording ending time in the scheduled recording setting interface to generate a scheduled recording request containing the recording starting time and the recording ending time. The reservation recording request and the instant recording request both belong to recording mode requests.

Step S112: and judging whether the recording mode request is an instant recording request or a reserved recording request.

In some embodiments, after receiving a recording mode request input by a user, a video recording program may determine whether the video recording request is an instant recording request or a scheduled recording request, for example, determine that the recording mode request is the instant recording request according to any one or more of a start time of recording, an end time of recording, and a recording duration that are not included in the recording mode request, and determine that the recording mode request is the scheduled recording request according to the start time of recording and the end time of recording that are included in the recording mode request.

Step S113: and if the recording mode request is an instant recording request, starting a video recording process.

Step S114: and if the recording mode request is a reserved recording request, judging whether the current time is the recording starting time in the reserved recording request.

Step S115: and if the current time is the recording start time, starting a video recording process.

In some embodiments, if the current time is the recording start time, the video recording process is started, and if the current time is not the recording start time, the video recording process is not started, and the step S114 is returned to.

Step S120: and after a video recording program is started under the first information source, monitoring the recording time length in real time.

In some embodiments, the display device may initiate a pre-configured monitoring process upon initiation of the video recording program, and in some embodiments, the monitoring process may also be configured to be initiated by the video recording program. In some embodiments, the monitoring process may be a system level process.

In some embodiments, the video recording process starts timing after being started, the timing time is the recording duration, and 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.

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, where when the video recording process is active, it indicates that the video recording process is performing video recording, and when the video recording process is inactive, it indicates that the video recording process is pausing or ending video recording. The monitoring process can obtain the recording duration of the video recording process according to the accumulated time when the video recording process is in an active state.

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

In some embodiments, the recording schedule menu may be configured to be displayed superimposed on a recording interface of a video recording program. When the current information source of the display equipment is the first information source recorded by the video recording program, if the video recording program is the foreground program of the display equipment, the display equipment can display the recording interface, and a user can see the recording progress menu on the recording interface. When the user presses the stop button on the remote controller, the recording stop control can be triggered, so that the video recording program is finished recording. When the current information source of the display device is not the first information source for recording the video recording program, for example, when the user switches the information source to the second information 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.

Step S130: and generating a recording state control with foreground display authority under all the information sources, wherein the recording state control is configured to display the recording duration.

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.

In some embodiments, the recording status control is generated by a system-level program or process, such as a monitoring process, so that the recording status control can have foreground display permission under all information sources, and can still be displayed in the foreground after the information sources are switched by the display device. For example, the recording state control may be configured to float on the current display interface of the display device when the display device host process is initiated or the monitoring process of the display device is initiated. When the current information source of the display equipment is the first information source recorded by the video recording program, if the video recording program is the foreground program of the display equipment, the display equipment can display the recording interface, and a user can see the recording state control on the recording interface. When the current information source of the display device is not the first information source for recording the video recording program, for example, when the user switches the information source to the second information 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, but can continue to display the recording state control in a floating window, so that the user can see the recording state control.

Step S140: and responding to a received information source switching request input by a user, switching the first information source into a second information source obtained according to the information source switching request, and controlling the video recording process to run in a background.

In some embodiments, after the user starts the video recording program under the first information source, the user can switch the information source of the display device by pressing the information source key on the remote controller. In some embodiments, after the user starts the video recording program under the first information source, pressing a menu key on the remote controller may call up a menu containing an information source switching control on the display device, and the trigger signal of the information source switching control may be to generate an information source switching request.

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

In some embodiments, after the display device switches the first information source to the second information source, the display device may control the video recording process to run in the background, so that the video recording program becomes a background program, and the video recording process can continue recording, where the foreground program is an application program under the second information source, such as a video-on-demand program.

In some embodiments, after the video recording program is converted into the background program, the monitoring process may continue to monitor the recording duration and the recording status of the video recording process, so as to update the recording status control.

Step S150: and displaying the recording state control on a display interface under the second information source.

In some embodiments, after the display device is switched to the second information source, the recording state control can be displayed on the display interface under the second information source in a floating mode, so that a 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 information source is being recorded, so that the problem that the user cannot acquire video recording information after switching the information sources is solved.

In some embodiments, the recording status control may be configured to be positionally adjustable, and a user pressing a screen recording button on the remote control may select the recording status control, and then pressing a direction key on the remote control may move the recording status control to a suitable position, e.g., to an upper, side, or bottom portion of a display area of the display device. In some embodiments, the size of the recording status control may also be configured to be adjustable.

Therefore, the recording state control is mounted on the system-level program or process, and when the information source is switched, the video recording program does not have the permission of foreground display, the recording state control can still be displayed on the current interface of the display device, so that a user can check the recording progress at any time.

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

In some embodiments, if the user wants to end the recording under the second information source, the user may press a screen recording button, the display device ends the video recording process under the first information source according to receiving a triggering instruction of the screen recording button, and the video recording process may be configured to automatically save the recorded video when the process is stopped.
