Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The screen transmission means that the current screen picture of the electronic equipment is synchronously displayed on the screen transmission terminal. The first electronic equipment is a transmitting end, and the screen transmission terminal is a receiving end. The electronic equipment and the screen transmission terminal can be the same type of electronic equipment, for example, the electronic equipment and the screen transmission terminal are notebook computers; the electronic device and the screen-transfer terminal may also be different kinds of electronic devices, such as an electronic device may be, but not limited to, a terminal device with image coding and data transmission capabilities, such as a personal computer, a notebook computer, a smart phone, a tablet computer and a portable wearable device. The screen transmission terminal can be intelligent interaction equipment capable of intensively displaying screen transmission images on the transmitting end, and can be specifically a display, an electronic whiteboard, an intelligent interaction panel, a curtain, a television, a video conference terminal and the like. The communication connection mode between the transmitting end and the receiving end can be communication modes such as Internet, local area network, bluetooth, wi-Fi or purple peak protocol (ZigBee).
Preferably, the screen transmission terminal is specifically configured with a display screen with a touch function, and the display screen with the touch function can be an infrared display screen, a capacitance display screen, a resistance display screen, an electromagnetic display screen, a pressure-sensitive display screen or the like. On a display screen with a touch function, a user can realize touch operation in a mode of touching the display screen by a finger or a writing pen, and correspondingly, the screen transmission terminal detects a touch position and responds according to the touch position so as to realize the touch function. In the description of the specific embodiment of the present solution, the screen-transfer terminal may install at least one application program with a writing function. The application program with writing function may be an application program of the operating system, and may also be an application program downloaded from a third party device or a server. Optionally, the application program has other editing functions, such as deleting, inserting pictures, drawing forms, drawing figures, and the like, in addition to the writing function based on the touch operation.
In one embodiment, as shown in fig. 1, a screen transmission method is provided, and the method is applied to a screen transmission terminal for illustration, and the method includes the following steps:
s101: and receiving the screen-passing image of the electronic equipment.
The execution main body of the embodiment is the screen transmission terminal. The electronic equipment and the screen transmission terminal can be connected through a wireless/wired network or through other communication cables, so that the current screen of the electronic equipment is synchronously displayed on the screen transmission terminal. And the screen transmission terminal receives the screen transmission image sent by the electronic equipment and displays the screen transmission image on the screen transmission terminal.
S102: detecting whether a first trigger operation is preset.
The detecting step can be performed by a corresponding detecting device. The detection device can be pre-installed in the screen transmission terminal. The preset trigger operation types in the detection device comprise a first trigger operation, a second trigger operation and a third trigger operation. When the screen transmission terminal is started, the detection device automatically operates, detects whether related trigger operation exists or not in real time, and detects and identifies the type of the trigger operation so as to execute the step corresponding to the trigger operation.
In this embodiment, the first trigger operation may be a marking operation. When the user wants to modify the screen image, the user can start the first triggering operation to mark the screen image.
In an embodiment, the first triggering operation may be a gesture of a user. For example, the screen of the screen terminal may be double-clicked by the user, or the user may make a biyer gesture, a heart gesture, or the like in front of the camera of the screen terminal, which is not limited herein. After the user makes a gesture action for triggering the first triggering operation, the detection device starts to start an editing mode after detecting the first triggering operation.
In another embodiment, the first triggering operation may be a specific device on the screen-transmitting terminal. For example, the first triggering operation may be an operation button or the like pre-installed on the screen transmission terminal, which is not limited herein. When the user needs to mark the screen image, the user can trigger the first triggering operation only by pressing the operation button. After the detection device detects the first trigger operation, the editing mode is started.
S103: if yes, generating a marking instruction, sending the marking instruction to the electronic equipment, and creating a transparent editing layer on the screen transmission image.
When the detection device detects that the first triggering operation is performed, a transparent editing layer is newly built on the screen image, the size of the editing layer is identical to that of the screen image, the editing layer and the screen image are completely overlapped, the editing layer and the screen image are mutually locked, the relative position between the editing layer and the screen image is guaranteed not to change, the editing layer and the screen image can be synchronously enlarged and reduced, and the user is guaranteed to accurately position the position to be marked when editing the mark. And because the editing layer is transparent, which is equivalent to attaching a transparent film to the screen-transfer image, the image seen by the user is still the screen-transfer image visually, and the existence of the editing layer is not felt, so that when the user marks the editing layer, the user can mark the screen-transfer image just like directly marking the screen-transfer image on the screen-transfer image, and the user can conveniently mark the screen-transfer image.
Meanwhile, the screen transmission terminal generates matching identification information at a preset position of the editing layer, and sends a marking instruction to the electronic equipment, so that the electronic equipment generates the same matching identification information at the same preset position of the current page according to the marking instruction, and the feedback image is matched with the editing layer later.
Further, if the detection device detects that the preset first trigger operation exists, the screen transmission terminal stops receiving the screen transmission image and/or sends a screen transmission stopping instruction to the electronic equipment. The electronic equipment is prevented from continuously sending a new screen image to the screen terminal, so that the relative position of the editing layer and the original screen image is changed, and the accurate positioning cannot be performed. Meanwhile, if the electronic equipment continuously sends the screen transmission image, resource waste can be caused, and the electronic equipment is always in a working state and is easy to cause blocking. After the first triggering operation is triggered, the electronic equipment stops screen transmission, so that the electronic equipment is in a low-load state, the heat generated by the electronic equipment can be reduced, the electronic equipment runs at the optimal performance, the phenomenon of blocking during screen transmission is avoided, and the user experience is improved. The screen transmission device has the advantages that transmission resources are saved, the screen transmission device does not need to continuously transmit screen transmission data, user experience is improved, and the phenomenon of blocking in the screen transmission process is not easy to occur.
S104: and generating marking information associated with the editing layer according to the marking instruction.
The screen transmission terminal generates mark information associated with the editing layer according to the mark instruction sent to the electronic equipment, the mark information is identical to the matching identification information generated by the electronic equipment, and matching can be performed according to whether the mark information is identical to the matching identification information, so that quick and accurate positioning is realized, and misplacement is prevented.
S105: and acquiring touch track information of the editing layer.
After a user writes or deletes a function or inserts a table or inserts a picture or an illustration graph or draws a table or draws a graph in the editing layer, the screen transfer terminal acquires touch track information of the editing layer.
Specifically, after a transparent editing image layer is newly built on the screen transmission image, the screen transmission terminal continuously captures operation or touch track information of a user, converts the touch track information into specific mark content and records the specific mark content on the newly built transparent editing image layer, so that when a preset second triggering operation is detected subsequently, the screen transmission image and the track information of the editing image layer are fused, and specific mark content on the editing image layer can be stored.
S106: detecting whether a second trigger operation is preset.
In this embodiment, the second trigger operation may be a save operation. And when the user finishes marking and needs to store the mark, starting a second triggering operation, and fusing the screen-passing image with the mark track information on the editing layer after the detection device detects the second triggering operation, so as to obtain a return image.
Likewise, in an embodiment, the second triggering operation may be a gesture of a user, for triggering the save function. For example, the screen of the screen terminal may be double-clicked by the user, or the user may make a biyer gesture, a heart gesture, or the like in front of the camera of the screen terminal, which is not limited herein. The second trigger operation is different from the first trigger operation in gesture action, so that different steps can be triggered and executed by the second trigger operation and the first trigger operation. And starting a storage mode after the user makes a gesture action triggering the second operation, and closing the editing mode.
In another embodiment, the second triggering operation may also be a specific device on the screen-transmitting terminal, which is used to trigger a save function. For example, the first triggering operation may be another operation button pre-installed on the screen transmission terminal, and the like, which is not limited herein. When the user needs to mark the screen image, the user presses the corresponding operation button to trigger the second triggering operation, so that the editing mode is closed, and the storage mode is started.
S107: if yes, fusing the screen-passing image with the editing layer track information to obtain a return image.
If the detection device detects a preset second triggering operation, the screen transmission terminal fuses the screen transmission image and the editing layer track information to form a return image, and the return image fuses all original information on the screen transmission image and all newly added mark information on the editing layer, so that the return image still has the same matching identification information at the same preset position of the editing layer; the screen transfer image and the editing layer track information are fused to obtain a return image, so that the mark content of the user can be quickly and conveniently stored, the user can also view the return image at the electronic equipment end, and the office efficiency of the user is improved.
In an embodiment, if a preset second triggering operation is detected, the screen transfer terminal stops receiving the message popup, and/or sends a message popup hiding instruction to the electronic device, so that the electronic device opens a do-not-disturb mode, and stops receiving the message popup.
In another embodiment, when the screen transfer application is started, the screen transfer terminal stops receiving the message popup, and/or sends a message popup hiding instruction to the electronic device, so that the electronic device starts a do-not-disturb mode, and message notifications of other third-party application programs are automatically hidden without user operation, so that the electronic device stops receiving the message popup.
In general, when content displayed on the electronic device is transmitted to the screen terminal for display, other third party applications may run on the electronic device, and other third party applications may receive a message notification during screen transmission, and at this time, the third party applications may pop up a message popup window to display specific message content, so that privacy of a user may be revealed, and meanwhile, progress of a screen transmission meeting may be disturbed. And the screen transmission terminal stops receiving the message popup window and/or the electronic equipment starts a do-not-disturb mode, so that message notification of other third-party application programs can be automatically hidden, privacy disclosure of a user is effectively prevented, and the screen transmission terminal is convenient to use. And the screen transmission terminal stops receiving the popup notification, so that when the screen transmission image and the editing layer track information are fused, the popup notification and the screen transmission image are fused together with the editing layer, the content of the returned image is blocked, and the omission of the user in the later period of correspondingly modifying the current page by comparing the returned image is prevented.
S108: and sending the return image and the associated marking information to the electronic equipment.
And the screen transmission terminal transmits the returned image to the electronic equipment, and the returned image is stored in the current page after being successfully matched with the current page. Compared with the prior complicated operation of recording or shooting and storing the mark information, the scheme of the application not only improves the efficiency of storing and recording for users, but also solves the problem that all mark contents cannot be completely recorded due to the existence of shooting dead zones, and even if people are more confused in the conference discussion process, all mark contents can be completely recorded, thereby bringing great convenience for users. And simultaneously, inserting the return image into the previous page or the next page of the current page, namely, setting the return image with the marking information adjacent to the corresponding page, so that a user can conveniently and correspondingly modify the current page by comparing the marking content on the return image in the later period.
Further, after the screen transmission terminal sends the return image to the electronic device, the screen transmission terminal automatically resumes receiving the screen transmission image and/or sends a screen transmission resuming instruction to the electronic device, so that the electronic device resumes screen transmission.
Further, the detecting device detects whether a preset third triggering operation exists. In this embodiment, the third triggering operation may be a delete operation. When the user wants to delete all the marks, the user can start the third triggering operation and start the deleting mode, so that the editing layer is deleted.
Likewise, in an embodiment, the third triggering operation may be a gesture of a user, for triggering a delete function. For example, the screen of the screen terminal may be double-clicked by the user, or the user may make a biyer gesture, a heart gesture, or the like in front of the camera of the screen terminal, which is not limited herein. The specific gesture actions of the third triggering operation and the first triggering operation and the second triggering operation are different, so that the related steps can be accurately executed. And after the user makes a gesture action triggering the third operation, starting a deleting mode, and deleting the editing layer by the user.
In another embodiment, the third triggering operation may be a specific device on the screen-transmitting terminal, which is used for triggering a deleting function. For example, the third triggering operation may be another operation button pre-installed on the screen transmission terminal, and the third triggering operation is not limited herein. When the user needs to delete all the marks on the screen image, the user presses the operation button, the deleting mode starts to be started, and the editing layer is deleted.
If the detection device detects that the preset third triggering operation exists, deleting the editing layer and recovering to receive the screen transmission image. And simultaneously, the screen transmission terminal sends a cancellation mark instruction and a screen transmission restoration instruction to the electronic equipment, so that the electronic equipment cancels the matching identification information of the current page and continues to send the screen transmission image to the screen transmission terminal.
Further, when the user mistakenly triggers the first triggering operation or after triggering the first triggering operation, the editing layer needs to be deleted after the user does not need to make any mark through the discussion, that is to say, the editing layer is still blank finally, the user can trigger the third triggering operation to delete the editing layer. And simultaneously, the screen transmission terminal sends a cancellation mark instruction and a screen transmission restoration instruction to the electronic equipment, so that the electronic equipment cancels the matching identification information of the current page and continues to send the screen transmission image to the screen transmission terminal.
After the screen transmission is finished, the screen transmission terminal generates a do not disturb mode closing instruction and sends the do not disturb mode closing instruction to the electronic equipment, and the electronic equipment receives the do not disturb mode closing instruction, closes the do not disturb mode and returns to a normal use state.
According to the screen transmission method, whether the related trigger operation exists or not is detected in real time through the automatic detection function of the detection device, and the type of the trigger operation is detected and identified, so that the step corresponding to the trigger operation is executed. And the required steps can be executed only by the gesture action of the user or triggering a specific device on the screen transmission terminal, so that the screen transmission terminal is convenient to use.
When the detection device detects that a first preset trigger operation exists, a transparent editing layer is newly built on the screen image, the editing layer and the screen image are locked with each other, so that the relative positions of the editing layer and the screen image are not changed, the editing layer and the screen image can be synchronously enlarged and reduced, and the user can accurately position the position to be marked when the user marks the mark. Further, the screen transmission terminal stops receiving the screen transmission image and/or sends a screen transmission stopping instruction to the electronic equipment, so that the electronic equipment stops screen transmission, is in a low-load state, can reduce the heat generated by the electronic equipment, enables the electronic equipment to run at the optimal performance, avoids the occurrence of blocking during screen transmission, and improves the user experience. Meanwhile, the electronic equipment can be prevented from continuously sending the screen transmission image, so that resource waste is caused. The screen transmission device has the advantages that transmission resources are saved, the screen transmission device does not need to continuously transmit screen transmission data, user experience is improved, and the phenomenon of blocking in the screen transmission process is avoided.
When the detection device detects a preset second triggering operation, the screen transmission terminal fuses the screen transmission image and the editing layer track information to form the return image, and the return image is sent to the electronic equipment. After the electronic equipment receives the returned image, matching is carried out according to the matching identification information on the preset position of the returned image and the same matching identification information on the same preset position of the current page, so that quick matching of the two is realized. And inserting the return image into a position after the current page is the previous page or the next page, so that the marking information is adjacently arranged with the corresponding page, and the user can conveniently carry out later comparison and modification. And simultaneously, the electronic equipment continues to restore the screen transmission. Compared with the prior art, the method has the advantages that the screen recording or shooting is not needed to save the marking information, the efficiency of recording and saving is greatly improved, the marking information is arranged adjacent to the corresponding page, and the user can conveniently and correspondingly modify the current page against the marking content on the return image in the later period.
When the detection device detects a preset third trigger operation, a user can trigger the third trigger operation to start a deleting mode, so that the editing layer is deleted.
In one embodiment, as shown in fig. 2, a screen transmission method is provided, and the method is applied to an electronic device for illustration, and the method includes the following steps:
s201: transmitting a screen transmission image to a screen transmission terminal;
the execution body of the embodiment is the electronic device. And the user operates on the electronic equipment to select a target screen file required by the interaction, and after the target screen file is selected, the electronic equipment converts the target screen file into the screen image and sends the screen image to the screen terminal, so that the screen image is displayed on the screen terminal.
S202: if a marking instruction sent by the screen transmission terminal is received, generating identification information matched with the current page according to the marking instruction;
when the detection device detects that a preset first triggering operation exists in the screen transmission process, the screen transmission terminal establishes a transparent editing layer on the screen transmission image, generates matching identification information on the editing layer and sends a marking instruction to the electronic equipment.
And when the electronic equipment receives the marking instruction sent by the screen transmission terminal, the same matching identification information is generated according to the marking instruction and is used for matching the return image with the editing layer.
Specifically, the generation of the identification information matched with the current page according to the marking instruction may be to create a new association list, and associate the position relationship of the corresponding pages with the identification information generated by the marking instruction.
Further, the electronic device receives a screen transmission stopping instruction sent by the screen transmission terminal, stops sending the screen transmission image to the screen transmission terminal, and prevents the original screen transmission image from being replaced by a new screen transmission image, so that the relative position of the editing image layer and the original screen transmission image is changed, and the accurate positioning cannot be performed. The electronic equipment is enabled to stop screen transmission, the electronic equipment can be prevented from being in a working state all the time and in a low-load state, the generated heat can be reduced, the electronic equipment can be enabled to operate in the best performance, the phenomenon of blocking during screen transmission is avoided, and the user experience is improved.
S203: judging whether a returned image and identification information of the returned image are received or not;
specifically, when the detection device detects that a preset first triggering operation exists, the screen transmission terminal builds a transparent editing layer on the screen transmission image, and acquires touch track information of the editing layer; when a preset second triggering operation is detected, the screen transmission image and the mark track information on the editing layer are fused, so that a return image is obtained, the return image is sent to the screen transmission terminal, and the screen transmission terminal receives the return image.
Wherein the determining step may be performed by a corresponding detecting means. The detection device can be pre-installed in the electronic equipment, and the detection device is used for judging whether the electronic equipment receives the return image or not.
S204: if yes, matching the target page according to the identification information of the returned image;
and if the electronic equipment receives the returned image and the identification information of the returned image, inquiring and matching are carried out according to the identification information of the returned image and the association list so as to match the target page.
And if the electronic equipment does not receive the returned image or receives a screen transmission restoration instruction sent by the screen transmission terminal, continuing to send the screen transmission image to the screen transmission terminal.
S205: and judging whether the number of the identification information of the target page is 1, if so, inserting the return image into the position before/after the target page.
After receiving the returned image and the identification information of the returned image, the electronic device inquires and matches a target page according to the identification information of the returned image and the association list, after successful matching, the position of the target page and the number of identifications corresponding to the target page are determined, if the number of the matched identification information of the target page is 1, the returned image is inserted into the position behind the front page or the rear page of the target page, so that the marking information is adjacently arranged with the corresponding page, and the later comparison and modification of a user are facilitated. Meanwhile, deleting the matching identification information of the target page successfully matched, and updating the association list, wherein the updating of the association list comprises the following steps: and adding the inserted return image to the list, and redetermining the position relation of each page of the list and the corresponding identification information thereof.
Further, after the electronic device receives the return image, the electronic device receives a screen transmission restoration instruction at the same time, and the electronic device continues to restore screen transmission. And after the screen transmission is finished, the electronic equipment receives the do-not-disturb mode closing instruction, closes the do-not-disturb mode and returns to the normal use state.
S206: and if the number of the identification information of the target page is not 1, replacing the target page with the return image.
Specifically, a target page is queried and matched according to the identification information of the returned image and the association list, after matching is successful, the position of the target page and the number of identifications corresponding to the target page are determined, if the number of the matched identification information of the target page is greater than 1, the matched target page is replaced by the returned image, and the association list is updated.
It should be noted that, after step S205, the file may insert a new return image as a new page, and the electronic device may revise the inserted return image after re-screening, and the identifier before the return image is already recorded in the association list, so that the return image has a plurality of identifiers during the re-screening process. Therefore, whether the page of the screen is the previously inserted return image can be determined through the number of the identification information, and the return image is the information processed by the screen transmission equipment operation, so that when the return image is obtained again, the last editing operation processing is judged, and at the moment, redundant pages can be reduced by replacing the previously inserted return image, and the return image confirmed by the latest operation can be reserved for comparison.
