The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the television, and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a kind of computer-readable storage medium, may include therein an operating system, a data storage module, a network communication module, a user interface module, and a screen projection program.
In the television shown in fig. 1, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 of the television of the present invention may be disposed in the television, and the television calls the screen projection program stored in the memory 1005 through the processor 1001 and executes the screen projection method provided by the embodiment of the present invention.
An embodiment of the present invention provides a screen projection method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a screen projection method according to the present invention.
In this embodiment, the screen projection method includes:
step S100, if the external picture of the screen is monitored, recording the external picture;
in this embodiment, it should be noted that the most common mode of the screen projection technology is to play a picture of a small-screen device on a large-screen device, so as to improve the viewing experience of a user. In this embodiment, a television is taken as an example of a large screen device, and specific description is given. The external screen of the projection refers to the projection content of the small-screen device on the large-screen device, for example, when a video on a mobile phone is projected on a television, the external screen refers to the video content projected on the television. When a user performs screen projection, according to a viewing requirement, it is often necessary to perform adjustment operations on a currently projected screen, for example, fast forward, fast backward, pause, play, and other operation modes. In some current conventional technologies, the adjustment operation is usually performed on a small-screen device, or the adjustment operation is performed by using a remote controller of a television, but the small-screen device has a small screen, and the accuracy is difficult to control during adjustment, for example, when a mobile phone casts a dance video on the television, a user wants to watch a previous dance action, because the time interval between the previous dance action and a current video picture is very small, when a manual video progress adjustment is performed at a mobile phone end, the adjustment is easy to be excessive, and the position of the user is difficult to be located to an actually required position. When the television remote control is used for adjustment, because corresponding control keys on the remote controller are different aiming at different applications, if the adjustment and the control are to be accurately carried out, a large amount of mapping is required, the workload is very large, and under some scenes that the network is unstable or the connection is unstable, the television remote control cannot accurately adjust and control the content of the screen shot by the mobile phone. In this example, a local video is formed by recording the external picture of the screen projection, and the accurate control of the screen projection content is realized by regulating and controlling the local video, so that the method is suitable for all screen projection scenes, and is particularly suitable for operation scenes when the picture needs to be viewed again. Specifically, when the television receives the external screen of the screen projection, the external screen is recorded.
Step S200, if a preset review instruction is triggered, generating a screen-casting video according to a recorded external picture, and playing the screen-casting video;
in this embodiment, the review instruction refers to an instruction to review the content that has been played. After the review instruction is triggered, the recorded external picture is played back. With the rise of new media industries, live video broadcasting is becoming a common way for information transfer in the society at present, for example, live game broadcasting, live sports broadcasting, live teaching broadcasting and the like. Many live video broadcasts do not have a playback function, and when a user participates in live broadcast watching, especially for some live teaching broadcasts, and needs to learn repeatedly, the live broadcasts do not have the playback function, and related contents cannot be confirmed again or reviewed in time. In this embodiment, when the review instruction is acquired, the recorded external picture is determined, the screen-casting video is generated according to the recorded external picture, and the screen-casting video is played.
And step S300, controlling the screen-casting video which is played according to the received adjusting instruction.
In this embodiment, it should be noted that the adjustment instruction refers to an instruction for adjusting the screen shot video, and includes operation instructions such as repeated watching, pausing, fast forwarding, and fast rewinding. After the screen-casting video is generated according to the recorded external picture, the played screen-casting video can be equivalent to the playing of local video at a television end, and at the moment, the playing control of the screen-casting video can directly correspond to the common control key of a television remote controller for the television. The adaptation of the screen-projecting application is not needed, and the mapping of the key meanings of the television remote controller is also not needed.
In the embodiment of the invention, if the external screen-casting picture is monitored, the external picture is recorded, the played external picture is preserved by recording the external screen-casting picture, a picture basis is provided for subsequent review, when a preset review instruction is monitored to be triggered, the screen-casting video is generated according to the recorded external picture, and the generated screen-casting video is played, so that review of screen-casting content is realized, the flexibility of controlling the screen-casting content is improved, the screen-casting video which is being played is controlled according to the received adjusting instruction, the counter control of the television terminal on the screen-casting content is realized, and the effectiveness of the television in counter control of the screen-casting content is improved based on the flexible control of the adjusting instruction.
Further, based on the first embodiment of the screen projection method of the present invention, a second embodiment of the screen projection method of the present invention is provided, and in step S100, if the external screen projected is monitored, the step of recording the external screen includes:
step a, determining an equipment identifier of screen projection equipment;
b, traversing a configuration file stored in a cloud based on the equipment identifier, and determining a target configuration file matched with the equipment identifier;
and c, if the external picture of the screen is monitored, starting to record the external picture based on the target configuration file.
In this embodiment, it should be noted that the screen projection device refers to a large-screen device, and is a device for playing the content of the screen projection. The device identifier refers to identification information of the screen projection device, such as a model, a movement, transportation and storage information and the like. The configuration file refers to a strategy for recording an external picture when screen projection equipment projects a screen, and the configuration files are different for different screen projection equipment. The target configuration file refers to a configuration file matched with the current screen projection equipment. The configuration file is determined by an operator according to actual requirements and equipment performance, and is uploaded to a cloud end by the operator for storage. The configuration file comprises related equipment identification information, the screen projection equipment acquires the related configuration file at the cloud end based on the equipment identification of the screen projection equipment, and the external screen projection picture is recorded according to the acquired configuration file. And when the same equipment identifier is matched with a plurality of configuration files, acquiring the latest configuration file in the plurality of configuration files, and taking the latest configuration file as a target configuration file, wherein the latest configuration file is determined according to the version number or the generation time. Specifically, an equipment identifier of the screen projection equipment is determined, and traversal is performed on the cloud end according to the equipment identifier so as to determine a target configuration file matched with the equipment identifier in all configuration files stored in the cloud end. And monitoring whether the projected external picture exists in real time, and recording the external picture according to the determined target configuration file when the external picture is monitored.
In this embodiment, the corresponding configuration file is located through the device identifier, so that the external picture recording targeted processing of different screen projection devices is realized, and the applicability of the screen projection method is improved.
Specifically, the step of recording the external picture based on the target configuration file includes:
step d, comparing the target configuration file with the local configuration file;
and e, if the target configuration file is the update version of the local configuration file, updating the local configuration file into the target configuration file, and starting to record the external picture based on the target configuration file.
In this embodiment, it should be noted that the local configuration file refers to a configuration file locally stored by the screen projection device before recording the external screen projected, and the local configuration file may be an initial configuration file carried by a factory or a target configuration file obtained from a cloud end when recording the external screen projected last time. When monitoring the external screen projected, an operator needs to first obtain the latest configuration file, namely a target configuration file, and compare the latest configuration file with a local configuration file to determine whether the local configuration file is the latest configuration file, and when the local configuration file is not the latest configuration file, the local configuration file is updated to the latest configuration file acquired from a remote end, so that the external screen is recorded according to the updated configuration file. When determining whether the local configuration file is the latest configuration file, comparing the version number or the file generation time of the local configuration file with the version number or the file generation time of the target configuration file to determine whether the local configuration file is the latest configuration file.
Specifically, whether a local configuration file exists in the screen projection equipment is determined, and if the local configuration file does not exist, an external screen projection picture is recorded based on a target configuration file; if the local configuration file exists, the local configuration file is compared with a target configuration file acquired from a cloud end, whether the target configuration file is an updated version of the local configuration file or not is determined, if the target configuration file is not the updated version of the local configuration file, recording an external screen shot based on the local configuration file is started, and if the target configuration file is the updated version of the local configuration file, the local configuration file is updated to be the target configuration file, so that the external screen shot is recorded based on the target configuration file.
In the embodiment, the configuration file of the screen projection device is ensured to be the latest version through the target configuration file, the adaptability of the configuration file is improved, and the strategy for recording the screen projection content is updated in real time according to actual requirements, so that the screen projection device can further effectively control the external screen projection picture.
Further, the recording the external picture based on the target profile includes:
step f, recording a recording time point for starting recording the external picture, and determining a recording duration in real time based on the recording time point after the external picture is started to be recorded;
step g, determining a target recording duration in the target configuration file, and detecting whether the recording duration is equal to the target recording duration;
and h, stopping recording the external picture if the recording duration is equal to the target recording duration.
In this embodiment, it should be noted that the recording duration refers to a length of time for the screen projecting device to record the external screen, the target recording duration refers to a recording duration defined in the configuration file, and the target recording duration limits a duration of time for recording the external screen based on the configuration file. Because the device performances of different screen projection devices are inconsistent, when an operator creates a configuration file, different recording durations can be defined based on the device performances of different screen projection devices. When the screen projection equipment uses the configuration file to record the external screen projection picture, the recording time length reaches the target recording time length specified in the configuration file, and the screen projection equipment stops recording. Specifically, a target recording time length in the target configuration file is determined, a recording time point for starting recording is recorded when the external picture is started to be recorded, the current recording time length is determined in real time after the external picture is started to be recorded, whether the recording time length is equal to the target recording time length or not is judged in real time, and the recording of the external picture is stopped when the recording time length is equal to the target recording time length.
Further, after the step of detecting whether the recording duration is equal to the target recording duration, the method further includes:
step i, if the recording duration is less than the target recording duration, determining whether the external picture stops screen projection;
j, if the external picture does not stop being projected, continuing to record the external picture;
or step k, if the external picture stops projecting the screen, stopping recording the external picture.
In this embodiment, it should be noted that, when the screen projection device records the projected external picture, if the recording duration does not reach the target recording duration, the projected external picture is continuously recorded. Specifically, determining a target recording time length in a target configuration file, recording a recording time point for starting recording when an external picture is recorded, determining a current recording time length in real time after the external picture is recorded, judging whether the recording time length reaches the target recording time length in real time, determining whether the external picture projected by the screen stops projecting the screen when the recording time length is less than the target recording time length, stopping recording if the external picture stops projecting the screen, and continuing to record the external picture if the external picture projected by the screen does not stop projecting the screen until the external picture stops projecting the screen or the recording time length is equal to the target recording time length.
In the embodiment, the configuration file is used for limiting the recording time of the screen projection equipment so as to perform different recording standards according to different equipment performances, so that the equipment resources are reasonably utilized to the maximum extent, and the influence on the normal use of the equipment due to the fact that the recording of the external pictures occupies too many equipment resources is avoided. And the external picture of the screen is recorded according to the target recording duration, so that the effectiveness of the screen projection equipment in controlling the external picture of the screen is further realized.
Further, after the step of controlling the video-on-screen being played according to the received adjustment instruction, the method further includes:
step l, monitoring whether an input return instruction exists;
and m, if the return instruction is monitored, stopping playing the screen-projected video and skipping to play the external picture of the screen projection.
In this embodiment, it should be noted that, when there is a small-screen device projecting a screen on a large-screen device, the large-screen device also is the screen projecting device, and recording of an external picture of the screen projecting is performed in the background, that is, the large-screen device may play a corresponding external picture at the same frequency as the small-screen device, and record the played external picture synchronously in the background. And when the screen projection equipment monitors a review instruction, playing a screen projection video corresponding to the recorded external picture, and continuously recording the playing content of the current small-screen equipment. For example, the mobile phone casts a video on the television, when the video is played for 5 minutes, the review instruction is triggered, at this time, the television plays the cast video recorded for 0-5 minutes, and if the mobile phone does not quit the cast of the external picture, the television continues to record the external picture after 5 minutes, such as the external picture of the 6 th minute, in the background. The return instruction is an instruction for jumping from a screen-projected video recorded in a playback mode to a real-time external picture with the same frequency as that of the small-screen device, for example, when a video is played for 5 minutes, the playback instruction is triggered, at this time, the television plays the screen-projected video recorded in 0-5 minutes, the mobile phone does not quit the screen projection of the external picture, and when the video is played for the 6 th minute, if the external device receives the return instruction in the 6 th minute, the screen-projected devices jump from the screen-projected video recorded in 0-5 minutes to the external picture played in the 6 th minute with the same frequency as that of the mobile phone. In an embodiment, if a review instruction is received in the 5 th minute, the screen projection device will play the screen projection video recorded in 0-5 minutes, and will synchronously record the external picture projected after the 5 th minute, the recorded external picture projected after the 5 th minute will be converted into the screen projection video to be connected with the screen projection video in 0-5 minutes, that is, if the screen projection device receives the adjustment instruction and controls the screen projection video played by the current screen projection device to fast forward, the content recorded in 5-7 minutes after 0-5 minutes can be fast-forwarded when the screen projection device receives the adjustment instruction and controls the fast forward of the screen projection video played by the current screen projection device.
In this embodiment, the playing picture of the screen projection device is controlled to return to the content currently played in real time by the small-screen device through the return instruction, so that the flexibility of the screen projection device in controlling the external picture of the screen projection is improved.
Referring to fig. 3, in an application scenario, the application scenario includes a picture source device, a TV terminal, a cloud terminal and an operator, the operator updates a configuration file and stores the configuration file in the cloud terminal, the TV terminal obtains the configuration file in the cloud terminal, compares the configuration file with a local configuration file, selects a latest configuration file, obtains an external picture when monitoring the external picture, starts to record the external picture of screen projection according to the configuration file, generates a screen projection video, plays the screen projection video when monitoring a review instruction, and can return to play the external picture of screen projection during playing, or pause, play, fast forward, fast backward, repeat watching the screen projection video.
Further, if the external picture of the screen shot is monitored, before the step of starting to record the external picture, the method further comprises the following steps:
n, if the equipment performance of the screen projection equipment meets a first preset performance standard, executing a step of starting to record an external picture if the external picture of the screen projection is monitored;
step o, if the performance of the equipment meets a second preset performance standard, determining whether an input trigger instruction exists when an external screen of a screen is monitored;
and p, if the trigger instruction exists, starting to record the external picture until the external picture stops being projected or until a storage module of the screen projection equipment reaches a storage limit, wherein the first preset information standard is lower than the second preset performance standard.
In this embodiment, it should be noted that the screen projection devices have different performances, that is, different screen projection devices need to have different recording standards when recording external pictures of a screen projection. For example, some screen projection devices have a small storage space, and therefore the recording time for recording external pictures needs to be limited. For another example, if the operating resources of some screen projection devices are in short supply, the resolution of the screen projection device for displaying the replayed screen projection video needs to be limited. The recording standard for recording the external picture of the screen projection device can be recorded in the configuration file. The first preset performance standard and the second preset performance standard are limiting conditions for recording external pictures projected by the screen projection equipment based on the equipment performance of the screen projection equipment, and if the corresponding preset performance standards are met, the corresponding recording standards under the preset performance standards are executed. The requirement of the second preset performance standard is higher than the first preset performance standard, that is, the device performance of the screen projection device meeting the second preset performance standard is better than the device information of the screen projection device meeting the first preset performance standard. The storage module has a storage limit that the storage space available for storing the screen shot video is full. The trigger instruction is an instruction for recording an external picture projected on a screen, and is manually triggered by a user. In this embodiment, the recording standard corresponding to the first preset performance standard is a limit recording duration, and when the recording of the external picture by the screen projection device meets the recording duration, the recording of the screen projection device is stopped; the winning recording standard of the second preset performance standard is unlimited in time and can be recorded until the storage space of the screen-casting device is occupied. Referring to fig. 4, in an application scenario, device performance of the screen projection device is defined in a configuration file, for example, a model, a movement, and a transportation and storage; and limits the recording standards under different device performances, such as the recording start time and the recording duration.
Specifically, the device performance of the screen projection device is determined, the device performance is matched with a first preset performance standard, if the device performance meets the first preset performance standard, the device performance is matched with a second preset performance standard, if the device information does not meet the second preset performance standard, whether an external screen of the screen projection exists is monitored, and when the external screen is monitored, the external screen is recorded. And if the performance of the equipment meets a second preset performance standard, monitoring whether an external screen for screen projection exists, determining whether an input trigger instruction exists when the external screen is monitored, and starting to record the external screen when the trigger instruction is monitored until the external screen stops screen projection or until a storage module of the screen projection equipment reaches a storage limit.
It can be understood that, when determining whether the device performance meets the first preset performance standard or the second preset performance standard, the device performance may be matched with the second preset performance standard first, and when the device performance does not meet the second preset performance standard, the first preset performance standard may be matched; the method may further include determining a preset performance criterion that matches the device performance for matching the device performance with the first preset performance criterion and the second preset performance criterion at the same time. In another embodiment, there may be more or less preset performance criteria to achieve the limitation of external picture recording for different screen projection devices for device performance of the screen projection devices.
