In addition, when the display screen 130 is an inductive touch screen, it can also be used to provide an interactive interface between a user and the video terminal 100.
It should be understood that the structure shown in fig. 1 is merely an illustration, and the video terminal 100 provided in the embodiment of the present application may have fewer or more components than those in fig. 1, or may have a different configuration from that shown in fig. 1. Further, the components shown in fig. 1 may be implemented by software, hardware, or a combination thereof.
Referring to fig. 2, fig. 2 is a flowchart illustrating an online video method according to an embodiment of the present disclosure, where the method is applied to the video terminal 100 shown in fig. 1. It should be noted that the online video method provided by the embodiment of the present application is not limited by the sequence shown in fig. 2 and the following, and the specific flow and steps of the online video method are described below with reference to fig. 2.
In step S100, when the number of participants is greater than the predetermined number, the video frames of the predetermined number of participants are displayed in the current video interface 131 of the display screen.
In addition, in the embodiment of the present application, the predetermined number may be a preset number, for example, but is not limited to 3, 6, 9, and the like, and the predetermined number may also be set in real time according to the physical size of the display screen, and for example, the video terminal stores the corresponding relationship between the physical size and the display number, for example, the display number corresponding to the physical size interval (0,6.2] inch is 3, the display number corresponding to the physical size interval (6.2, 15.6] inch is 6, and the display number corresponding to the physical size interval (15.6, 32] inch is 9.
Based on the above description, in the embodiment of the present application, the current video interface 131 of the display screen may include an appointed number of first windows 1311 for displaying video images of participants, and the appointed number of first windows 1311 may be arranged in a row-column manner in the current video interface 131 of the display screen, for example, when the appointed number is 3, 3 first windows 1311 may be arranged in 1 row, when the appointed number is 6, 6 first windows 1311 may be arranged in 2 rows and 3 columns (as shown in fig. 3), and when the appointed number is 9, 9 first windows 1311 may be arranged in 3 rows and 3 columns.
In the embodiment of the present application, it should be noted that, at present, there are many types of large-scale video conferences, for example, a common video conference, an online teaching classroom, and the like. For the online teaching classroom, a teacher initiates a video conference as a video initiator, and participants mainly participate in listening, based on which, in the embodiment of the present application, the current video interface 131 of the display screen may further include a second window 1312 for displaying the video initiator, where the window size of the second window 1312 is larger than that of the first windows 1311 and is located above (as shown in fig. 4) a preset number of the first windows 1311.
Step S200, when the picture switching request is monitored, determining the video pictures of the replaced participants from the video pictures of the appointed number of participants, and obtaining the video pictures of the target participants.
Referring to fig. 5, in the embodiment of the present application, as a first implementation manner, a screen switching request may be generated through the following steps:
step S010, when the touch control gesture aiming at the display screen is monitored, whether a switching gesture matched with the touch control gesture exists in a preset switching gesture set or not is judged.
In the embodiment of the application, the switching gesture existing in the switching gesture set includes a designated switching gesture, a slide-up gesture, a slide-down gesture, a left slide gesture, a right slide gesture, and the like. When a touch gesture aiming at the display screen is monitored, firstly, whether the touch gesture is an appointed switching gesture or a straight line gesture is judged, and if the touch gesture is the appointed switching gesture or the straight line gesture, a switching gesture matched with the touch gesture exists in a preset switching gesture set.
Exemplarily, if the touch gesture comprises a first single-point gesture with the holding time being greater than or equal to a first appointed time length, and the interval time length between the trigger time and the first single-point gesture is less than a second appointed time length, and the trigger position is a second single-point gesture at an appointed position, determining that the switching gesture matched with the touch gesture is an appointed switching gesture, if the touch gesture is a straight-line gesture, obtaining an actual straight line formed between a starting point and a finishing point of the touch gesture, then establishing a plane coordinate system by taking the starting point of the touch gesture as a center, and finally determining the switching gesture matched with the touch gesture according to the angle between the actual straight line and an X positive half shaft in the plane coordinate system.
For example, when the angle between the actual straight line and the positive X-axis in the planar coordinate system is included in the angle range [45 °,135 °, the switching gesture matching the touch gesture is determined to be the up-slide gesture, when the angle between the actual straight line and the positive X-axis in the planar coordinate system is included in the angle range (-45 °, -135 ° ], the switching gesture matching the touch gesture is determined to be the down-slide gesture, when the angle between the actual straight line and the positive X-axis in the planar coordinate system is included in the angle range [135 °,180 ° ] or (-135 °, -180 ° ], the switching gesture matching the touch gesture is determined to be the left-slide gesture, and when the angle between the actual straight line and the positive X-axis in the planar coordinate system is included in the angle range [ -45 °,45 °), the switching gesture matching the touch gesture is determined to be the left-slide gesture.
Step S020, if a switching gesture matching the touch gesture exists in the switching gesture set, obtaining a picture switching rule corresponding to the switching gesture.
The picture switching rule corresponding to the designated switching gesture is designated switching, that is, the video picture displayed in the first window 1311 corresponding to the designated switching gesture in the current video interface 131 of the display screen is determined as the video picture of the replaced participant and is replaced with the video picture of the target participant.
The frame switching rule corresponding to the slide-up gesture is to replace the video frames with one line as a step value, and obtain the video frames of the corresponding number of target participants to be displayed in the first window 1311 in the bottom line. Taking the agreed number as 6, that is, the current video interface 131 of the display screen includes 6 first windows 1311, and the 6 first windows 1311 are arranged in 2 rows and 3 columns as an example, the picture switching rule corresponding to the slide-up gesture is to replace the video pictures in the first windows 1311 in the first row with the video pictures in the first windows 1311 in the second row, and obtain the video pictures of a corresponding number of target participants to display in the first windows 1311 in the second row.
The frame switching rule corresponding to the slide-down gesture is to replace the video frames with one line as a step value and obtain the video frames of the corresponding number of target participants to be displayed in the top row of the first window 1311. Taking the agreed number of 6, that is, the current video interface 131 of the display screen includes 6 first windows 1311, and the 6 first windows 1311 are arranged in 2 rows and 3 columns as an example, the picture switching rule corresponding to the downslide gesture is to replace the video picture in the first window 1311 in the second row with the video picture in the first window 1311 in the first row, and obtain the video pictures of a corresponding number of target participants to display in the first window 1311 in the first row.
The frame switching rule corresponding to the left slide gesture is to replace the left with one row as a step value, and obtain video frames of a corresponding number of target participants to display in the first window 1311 in the rightmost row.

In addition, it should be noted that the target participant may be selected according to a preset circular display sequence, or according to a specific request triggered by a user. In the embodiment of the application, after the picture switching rule corresponding to the switching gesture is obtained, if the generation of the designated request is monitored in the third appointed time, the target participant is selected according to the designated request triggered by the user, and otherwise, the target participant is selected according to the preset circular display sequence.
Step S030 generates a screen switching request according to the screen switching rule.
In the embodiment of the application, after the picture switching rule corresponding to the switching gesture is obtained and the obtaining mode of the target participant is determined, the information of the target participant is further obtained, and then, a picture switching request is generated according to the picture switching rule and the information of the target participant.
Referring to fig. 6, in the embodiment of the present application, as a second implementation, a screen switching request may also be generated through the following steps:
step S040, when it is monitored that voice information is input, determines whether there is a switching keyword in the voice information.
When the fact that voice information is input is monitored, word segmentation processing can be carried out on the monitored language information through a preset word segmentation tool to obtain a plurality of independent words, wherein the preset word segmentation tool can be, but is not limited to, a character string matching system, a word segmentation system based on statistics and the like. For example, when the voice input information is "replace the video picture of lie four with the video picture of zhang, the individual words obtained after the word segmentation processing is performed on the voice information include" replace with "," zhang "," of "," video picture "," replace "," lie four "," of "," video picture ". For another example, when the voice input information is "replace the video picture of the participant in the first window with the video picture of zhang san", the obtained individual words include "replace", "first window", "middle", "participant", "video picture", "replace", "zhang", "etc." after the word segmentation processing is performed on the voice information.
After obtaining the plurality of individual words, the plurality of individual words may be matched with the switching keyword in the keyword database to determine whether the switching keyword exists in the voice message. In the embodiment of the present application, the switching keyword in the keyword database includes the identification number of the first window 1311, the information of the participant, and the substitute verb. The identification number of the first window 1311 may be a window number, a window row number, and the like, the participant information may be names of participants, video account information, and the like, and the substitute verb includes "replace", "switch", "delete", "replace", "switch", and the like.
And step S050, if the voice information has the switching keyword, generating a picture switching request according to the switching keyword.
When the switching keywords exist in the voice information, all the keywords included in the voice information are extracted, and the indication short message is synthesized according to all the extracted keywords and the front-back logic relation among the keywords. Therefore, it can be understood that the replacing object and the replaced object are included in the indication short message. Similarly, taking the voice input information as "replace the video picture of lie four with the video picture of zhang san", the extracted keywords include "zhang san", "replace", and "lie four", and the synthesized indication short message is "replace lie four with zhang san", where the video picture of zhang is the replacement object and the video picture of lie four is the replaced object. Then, taking the voice input information as "replace the video picture of the participant in the first window with the video picture of zhang san" as an example, the extracted keywords include "first window", "replace" and "zhang san", the synthesized indication short message is "replace the first window with zhang san", wherein the video picture in the first window is a replaced object, and the video picture of zhang san is a replaced object.
After obtaining the indication short message, the indication short message may be used as a screen switching request.

And step S204, acquiring the video picture of the target participant according to the information of the target participant.
Taking a slide-up gesture of a switching gesture matched with the touch gesture, and taking as an example that the current video interface 131 of the display screen includes 6 first windows 1311, and the 6 first windows 1311 are arranged in 2 rows and 3 columns, at this time, the picture switching rule corresponding to the slide-up gesture is to replace the video pictures in the first windows 1311 in the first row with the video pictures in the first windows 1311 in the second row, and obtain the video pictures of a corresponding number of target participants to display in the first windows 1311 in the second row. Therefore, the target window to be subjected to screen switching includes each first window 1311 in the video interface 131 of the display screen at present.
For the first window 1311 in the first row, the target participant corresponding to the first window 1311 is a video picture in the first window 1311 in the second row, and for the first window 1311 in the second row, the target participant corresponding to the first window 1311 is a target participant selected according to a specified request triggered by a user, or a target participant selected according to a preset circular display sequence.
