Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
In the embodiment of the invention, under the condition that the video network video conference comprises the first participant terminal and the second participant terminal, if a service instruction which enables the video picture of the second participant terminal to change is generated in the video conference, another service instruction can be sent to the first participant terminal, so that the video picture of the first participant terminal can change in linkage with the video picture of the second participant terminal, and the video picture displayed by the first participant terminal can be updated in time.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for adjusting a video frame according to the present invention may be applied to an electronic device for controlling a video conference, where the electronic device may be a video-networking conference scheduling tablet computer, and a video-networking conference scheduling tablet system is disposed in the tablet computer to control a participant terminal (i.e., a video-networking terminal), so as to control a video-networking video conference. The video networking conference scheduling tablet system can be in an App (Application) form and arranged in a tablet computer.
The control method has the advantages that the platform computer is used for controlling the video networking conference, so that the control mode of the traditional video conference by a desktop computer or directly by a control hardware system is changed. Compared with a desktop computer, the tablet computer has lighter body, convenient carrying and simple operation, and is beneficial to meeting control personnel to better control the video conference.
The method specifically comprises the following steps:
step 101: and sending the first service instruction to the target terminal.
The first service instruction is used for adjusting a video picture displayed when the target terminal is in the video conference.
In the embodiment of the invention, the electronic equipment for controlling the video conference can send the first service instruction to the target terminal so as to adjust the video picture displayed when the target terminal is in the video conference.
For example, a general participant terminal will display a video stream picture on the speaker side (i.e. a conference environment picture on the speaker side and a picture of a main video source of the speaker), but as the speaker, when there is a need, the participant terminal may connect an external video source (i.e. an auxiliary video source) to a data line (such as a high-definition multimedia transmission line, english "High Definition Multimedia", abbreviated as HDMI line) through the data line, and send the video stream of the external video source to other participant terminals for display. When the first service instruction is used for controlling the participant terminal to switch the displayed main video source picture of the speaking party to the auxiliary video source picture, the video picture displayed by the participant terminal receiving the first service instruction is switched from the main video source picture of the speaking party to the auxiliary video source picture.
The speaking party is a conference role with the participant terminal, participants can conduct conference speaking through the conference role, and other participant terminals can receive audio and video transmitted from the speaking party.
Wherein the number of the target terminals is at least one.
Step 102: and under the condition that the first service instruction is detected to be successfully executed, sending a second service instruction to the first participant terminal.
In the embodiment of the invention, the target terminal receiving the first service instruction can send the execution result of the first service instruction to the electronic equipment for controlling the video conference, so that the electronic equipment for controlling the video conference can know whether the first service instruction is successfully executed.
The electronic device for controlling a video conference may send a second service instruction to the first participant terminal upon detecting that the first service instruction was successfully executed. The second service instruction is used for adjusting the video picture displayed by the first reference terminal according to the video picture change of the target terminal. The target terminal added into the video conference belongs to a second participant terminal. Referring to fig. 2, the start of a video conference may be controlled by a video networking conference scheduling flat-panel system installed in an electronic device for controlling the video conference, after the video conference is started, a first service instruction may be sent to a second participant terminal, and after the first service instruction is successfully executed, a second service instruction is sent to the first participant terminal, so that the first participant terminal adjusts a displayed video picture according to the second service instruction. After the first service instruction is failed to be executed, the first service instruction can be continuously sent to the second participant terminal.
The first participant terminal displays video pictures displayed by the second participant terminal in a split screen mode, and the second participant terminal is a participant terminal except the first participant terminal in the video conference. For example, the first participant terminal is terminal a, and the second participant terminal includes: and the terminal A can respectively display the video picture displayed by the terminal B, the video picture displayed by the terminal C and the video picture displayed by the terminal D in each split screen in a split screen mode.
The following describes the contents of this step, continuing with the foregoing example as an example. Under the condition that the first service instruction is used for controlling the second participant terminal to switch the main video source picture of the displayed speaking party to the auxiliary video source picture, if the electronic equipment for controlling the video conference detects that the first service instruction is successfully executed by the second participant terminal, the second service instruction is sent to the first participant terminal, and the first participant terminal is controlled to switch the video picture of the displayed second participant terminal from the main video source picture of the speaking party to the auxiliary video source picture so as to synchronously change with the video picture of the second participant terminal.
In the embodiment of the invention, under the condition that the video conference comprises the first participant terminal and the second participant terminal, if a first service instruction which enables the video picture of the second participant terminal to change is generated in the video conference process, the second service instruction can be sent to the first participant terminal, so that the video picture displayed by the first participant terminal can synchronously change with the video picture of the second participant terminal, thereby updating the video picture displayed by the first participant terminal in time and facilitating the user to view the latest video picture. The technical scheme provided by the embodiment of the invention does not need to manually adjust the video picture of the first participant terminal by the user, reduces the control operation of the user and is convenient for the user to control the video conference.
In order to better understand the above technical solution provided by the embodiments of the present invention, a more detailed explanation will be given below.
In the embodiment of the invention, the target terminal can be at least one second participant terminal, and can also be terminal equipment which does not join in the video conference.
As an alternative embodiment, in the case that the target terminal is a terminal device that does not join the video conference, the first service instruction may be a service instruction for adding the target terminal to the video conference, and controlling the target terminal to display the first video picture.
The target terminal may join the video conference according to the first service instruction, and display a conference video stream picture (such as a video stream picture on the speaker side) pushed by the electronic device for controlling the video conference. Because the terminal equipment participating in the video conference is added, and the terminal equipment displays video pictures, the electronic equipment for controlling the video conference can send a second service instruction to the first participant terminal, wherein the second service instruction is used for adding the first video picture displayed by the target terminal after joining the video conference to the video picture displayed by the first participant terminal, and the electronic equipment for controlling the video conference can push the video stream corresponding to the first video picture displayed by the target terminal to the first participant terminal, so that the first participant terminal displays the first video picture displayed by the target terminal. At this time, the first reference terminal is adjusted from the original N split screens to n+x split screens, where x is the number of target terminals. For example, the second participant terminal originally has four split screens, and four video pictures displayed by the second participant terminal are respectively displayed. After a second participant terminal is added in the video conference, the four split screens are adjusted to five split screens so as to display video pictures displayed by the newly added second participant terminal.
As an alternative embodiment, in the case that the target terminal is at least one second participant terminal, the first service instruction may be configured to remove the target terminal from the video conference, and control the target terminal to stop displaying the first video frame, where the electronic device configured to control the video conference stops pushing the conference video stream to the target terminal.
Because the terminal devices participating in the video conference are reduced, the video frames displayed by the first participant terminal need to be synchronously updated, so the electronic device for controlling the video conference can send a second service instruction to the first participant terminal, the second service instruction is used for deleting the first video frame displayed by the target terminal from the video frames displayed by the first participant terminal, and the electronic device for controlling the video conference also stops pushing the video stream corresponding to the first video frame displayed by the target terminal to the first participant terminal. At this time, the second participant terminal is adjusted from the original N split screens to N-x split screens, where x is the number of target terminals, and N is greater than or equal to x. For example, the second participant terminal originally has four split screens, and video pictures displayed by the four second participant terminals are displayed respectively, and after one second participant terminal is reduced in the video conference, the four split screens are adjusted to three split screens so as to display the video pictures displayed by the existing second participant terminal in the video conference.
As an alternative embodiment, in the case that the target terminal is at least one second participant terminal, the first service instruction may also be an instruction for switching the first video frame displayed by the target terminal to the second video frame.
The first service instruction may specifically be a speaker switching instruction, a primary and secondary source switching instruction (i.e., a switching instruction between a primary video source and a secondary video source), and so on. For the instruction of switching the speaking party, besides being performed between the participant terminals, the external monitoring equipment can be switched to the speaking party, and the video picture collected by the monitoring equipment is pushed to the participant terminals for display. Because the video picture of the target terminal changes, the video picture displayed by the first participant terminal needs to be synchronously updated, so the electronic device for controlling the video conference can send a second service instruction to the first participant terminal, the second service instruction is used for switching the first video picture of the target terminal displayed by the first participant terminal into a second video picture, and the electronic device for controlling the video conference can push the video stream corresponding to the second video picture displayed by the target terminal to the first participant terminal, so that the first participant terminal displays the second video picture displayed by the target terminal.
The first video picture is a picture of a first video stream, the second video picture is a picture of a second video stream, and the first video stream and the second video stream are different video streams.
As an alternative embodiment, in the case that the target terminal is all the second participant terminals, the first service instruction may also be for controlling the target terminal to display full screen and display only the third video picture (the third video picture is a picture of the third video stream). For example, the user controls all the second participant terminals to be displayed full screen and only the picture of the video stream on the terminal D side among the second participant terminals to be displayed through the electronic device for controlling the video conference.
Because the video frames of the target terminal are changed, the video frames displayed by the first participant terminal need to be synchronously updated, so the electronic device for controlling the video conference can send a second service instruction to the first participant terminal, the second service instruction is used for controlling the first participant terminal to display the third video frames in a full screen manner, and the electronic device for controlling the video conference can push the third video streams to the target terminal so that the first participant terminal can display the third video frames in a full screen manner.
As an alternative embodiment, the target terminal is at least one second participant terminal, and the target terminal displays the first video frame and the fourth video frame in the first split-screen mode, respectively. The first video picture is a picture of a video stream of the other participant terminal side, and the fourth video picture is a picture of a video stream of the target terminal itself side.
For example, after the video conference is started, the electronic device for controlling the video conference may control all the second participant terminals to enter the first split screen mode (assuming that the first split screen mode is a split screen, and the display areas of the two split screens are one large and one small), set the speaker as the terminal B in the second participant terminals, and push the video stream on the terminal B side to the other second participant terminals, while the other second participant terminals display the pictures of the video stream on the terminal B side (corresponding to the first video picture) in the large split screen, and display the pictures of the video stream on the self side (corresponding to the fourth video picture) in the small split screen. In addition, the electronic device for controlling the video conference may push the video stream of the terminal B, the video streams of the other second participant terminals, and the first split screen mode information to the first participant terminal, so that the first participant terminal displays the video picture displayed by each second participant terminal according to the first split screen mode.
In the embodiment of the invention, the first service instruction may be used for switching the first split screen mode of the target terminal to the second split screen mode. For example, the two split screen modes with one size are switched to the two split screen modes with the same size. Specifically, the two split screens with equal size can be arranged left and right, or can be arranged up and down, and the specific situation can be set according to actual requirements.
After the split screen mode is switched, the target terminal displays the first video picture and the second video picture according to the new split screen mode. In order to update the video frame displayed by the first participant terminal and the frame displayed by the target terminal synchronously, the electronic device for controlling the video conference may send a second service instruction to the first participant terminal, where the second service instruction is used to switch the split screen mode of the video frame of the target terminal displayed by the first participant terminal from the first split screen mode to the second split screen mode. Specifically, the second service instruction includes second split screen mode information, so that the first participant terminal can adjust the split screen mode of the video picture of the displayed target terminal according to the second split screen mode information.
When the target terminal displays the first video picture and the fourth video picture in the first split screen mode, if an event that the first video picture is switched to the second video picture occurs, the video picture of the target terminal displayed by the first participant terminal is updated synchronously according to the mode. For example, after the video conference is started, the terminal C in the second participant terminals is set as the speaking party, and then the other second participant terminals respectively display the picture of the video stream from the terminal C side and the picture of the video stream from the first participant terminal in the split screen mode, and the first participant terminal displays the video picture displayed by each second participant terminal in the split screen mode. When the speaking party is switched from the terminal C to the terminal D, the video pictures displayed by the other second participant terminals are changed along with the operation of switching the speaking party, so that the picture of the video stream originally displayed from the terminal C side is switched to the picture of the video stream from the terminal D side, and the picture of the video stream from the self side is kept unchanged. The electronic device for controlling the video conference sends a service instruction to the first participant terminal according to the service operation of switching the speaking party, and pushes the video stream from the terminal D side to the first participant terminal, so that the first participant terminal adjusts the video picture of the second participant terminal with the displayed video picture changed, and switches the picture of the video stream from the C side originally displayed to the picture of the video stream from the terminal D side.
As can be seen from the foregoing description of the optional embodiments, the technical solution provided by the embodiments of the present invention not only can update the video image displayed by the first participant terminal in time, improve the linkage between the first participant terminal and the second participant terminal, but also does not need to manually adjust the video image of the first participant terminal by a user, thereby reducing the control operations of the user and facilitating the control of the user on the video conference.
The technical solution provided by the embodiment of the present invention is further explained below by using a specific example.
In this example, the electronic device for controlling the video conference is a video networking conference scheduling tablet (hereinafter simply referred to as tablet) in which a video networking conference scheduling tablet system is provided.
Referring to fig. 3, before a video conference is started, a certain terminal ready for a conference may be set as a first participant terminal and other terminals ready for a conference may be set as second participant terminals through an internet-of-view conference scheduling tablet system in the tablet computer. After the video conference is started, the video stream picture displayed by the second participant terminal can be set to the first participant terminal by the video networking conference scheduling tablet system in the tablet computer. Specifically, the video-on-line conference scheduling tablet system may invoke an interface for setting up video stream pictures, sending scheduling requests for the video stream pictures to a video-on-line conference scheduling server (on which the video-on-line conference scheduling service system is set). And the video networking conference scheduling server sends scheduling instructions of corresponding video stream pictures to the video networking autonomous server according to the received scheduling request, and feeds back processing results to the video networking conference scheduling flat-panel system. And the video networking autonomous server sends a corresponding video stream picture to the first participant terminal according to the received scheduling instruction, and feeds back a processing result to the video networking conference scheduling server. And the first participant terminal displays the video stream pictures after receiving the corresponding video stream pictures sent by the video networking autonomous server, and feeds back the receiving results to the video networking autonomous server.
After the video networking conference scheduling flat-panel system sends out a first service instruction (such as switching a speaking party, switching a main source and an auxiliary source, adding a participant terminal, removing the participant terminal, displaying a video stream picture on a screen, and the like), the participant terminal which receives the first service instruction executes corresponding service operation. And under the condition that the participant terminal receiving the first service instruction feeds back that the service operation is successfully completed, the video network conference scheduling flat-plate system sends a second service instruction to the first participant terminal according to the first service instruction, and the video picture displayed by the first participant terminal is updated in time. The first participant terminal which completes the video picture update can feed back the result to the video networking conference scheduling flat-panel system.
Under the condition that the operation of the participant terminal receiving the first service instruction is not successfully completed, the video networking conference scheduling flat-plate system can reissue the first service instruction to the corresponding participant terminal.
In the case that the video stream picture needs to be pushed to the first participant terminal again, the video stream picture can be called according to the mode, and the called video stream picture is pushed to the first participant terminal.
Finally, it should be noted that the reference terminal in the embodiment of the present invention may be an internet-of-view terminal, and the internet-of-view terminal may be externally connected with a display device to display a video picture. In addition, the first participant terminal may display a picture of the video stream on its own side, and the number of the first participant terminals is at least one.
In summary, in the embodiment of the present invention, when the video conference includes the first participant terminal and the second participant terminal, if a first service instruction is generated in the video conference process, which causes the video frame of the second participant terminal to change, the second service instruction may be sent to the first participant terminal, so that the video frame displayed by the first participant terminal may change synchronously with the video frame of the second participant terminal, thereby updating the video frame displayed by the first participant terminal in time, and facilitating the user to view the latest video frame. The technical scheme provided by the embodiment of the invention does not need to manually adjust the video picture of the first participant terminal by the user, reduces the control operation of the user and is convenient for the user to control the video conference.
