In specific application, when a subscriber enters a video conference, the subscriber receives a video picture request and needs to know information to read, the system verifies whether the subscriber authenticates and checks, and if so, the subscriber receives the video picture of the initiator. The initiator only needs to input the video picture request information in a convenient mode.
The initiator only needs to input the video picture request awareness information in a convenient mode, and the system pushes the video picture to the participant who requests to receive the video picture of the initiator for the participant to check, the initiator does not need to make a commitment book by typesetting, the participant does not need to download, print and sign, the convenience is improved, the user experience is improved, in addition, based on the checking condition of the participant, whether the participant really checks and reads the video picture request awareness information or not is verified, and disputes caused by the fact that the participant does not violate the request awareness information after checking roughly are avoided.
Example 2
In one embodiment, in the step 1, acquiring the video picture request notification information input by the initiator includes:
acquiring video picture request awareness information input by an initiator; the self-propelled input includes: one or two of manual input and voice input are combined;
and/or the presence of a gas in the gas,

there are two ways for the initiator of the video conference to input the video picture request notification information: 1. self-input; the self-input mode includes manual typing input and voice input. 2. The system displays a preset list for selection; there are a plurality of video picture types in the preset video picture type list, for example: lecture materials and business secrets; the preset video frame request knowing condition list corresponding to the video frame type includes video frame request knowing conditions that may be special requirements when the initiator shares a video frame of a certain video frame type, for example: the video picture type is teaching material, and the video picture request needs to be known under the condition that if the video picture is transmitted outside, legal responsibility needs to be taken. The two modes can be carried out alternatively or together.
The embodiment of the invention introduces two modes for the initiator to input the video picture request awareness information, thereby improving the applicability of the system; the first mode is used for users to input by themselves, the requirements of some users with special requirements are met, the second mode can be selected by the users, the input efficiency of the video picture request information needing to be known is improved, and the method is more humanized.
Example 3
In one embodiment, the step 3: acquiring the viewing condition of the video picture request awareness information viewed by the subscriber, comprising the following steps:
acquiring the content weights of a plurality of content items in the video picture request awareness information;
taking the content item with the content weight smaller than a preset content weight threshold value as a first target content;
acquiring a first viewing duration for viewing the first target content by the subscriber;
taking the content item with the content weight greater than or equal to the content weight threshold value as second target content;
acquiring a first sight movement condition when the joiner views the second target content;
and integrating the first viewing time of the first target content viewed by the joiner and the first sight movement condition when the second target content is viewed by the joiner to obtain the viewing condition.
The working principle and the beneficial effects of the technical scheme are as follows:
the video picture request must know a plurality of content items in the information and is a special requirement of a strip of initiator for the video picture of the initiator. The video frame requests that the information be required to be displayed, each of the pieces is displayed page by page. Generally, the importance of specific requirements is high or low, for example: "cannot be transmitted outside, if the transmission outside needs to bear xxxx responsibility. "important is higher" and "please close the microphone while watching" is less important. Therefore, a content weight of the content item is introduced, the size of the content weight indicating the importance of the content item. The predetermined content weight threshold is a constant. If the content weight is smaller than the content weight threshold, the importance of the content item is low, the content item is used as first target content, whether the content item is viewed and read by the subscriber is determined according to the size of first viewing time when the subscriber views the first target content, the first viewing time is obtained, when the subscriber turns pages to the first target content, timing is started, and when the subscriber turns pages again, timing is stopped, and the content item can be obtained. If the content weight is greater than or equal to the content weight threshold, it is indicated that the importance of the content item is high, the content item is used as second target content, whether the content item is viewed and read by the jointer is determined according to a first sight movement condition when the jointer views the second target content, the first sight movement condition is a sight track, a sight movement speed, a position and a stay time of a sight stay point and the like, the start-stop time can also be determined based on page turning when the first sight movement condition is acquired, sight acquisition can be realized based on a camera and the like, the method belongs to the field of the prior art, and details are not given. And integrating the first viewing time of the first target content viewed by the joiner and the first sight movement condition when the joiner views the second target content as the viewing condition.
According to the embodiment of the invention, the checking condition is acquired according to the importance of the content item, when the importance of the content is lower, only the checking duration is acquired, and when the importance of the content is higher, the sight line movement condition is acquired, so that the acquisition efficiency is improved, the acquisition resources are reduced, and meanwhile, the method is more intelligent.
Example 4
In one embodiment, obtaining content weights for a plurality of content items in the video picture request awareness information comprises:
traversing the content items in sequence;
acquiring the input mode of the traversed content item during each traversal;
when the input mode is self-input by an initiator, performing semantic extraction on the traversed content items to obtain first content semantics, and determining the content weight of the traversed content items based on the first content semantics and a preset content semantics-content weight library;
otherwise, determining the content weight of the traversed content item based on a preset content weight library.
The working principle and the beneficial effects of the technical scheme are as follows:
the input modes of the content item are classified into a self-input and a list-based selection input. When the input mode of the content item is self-input, the content weight is required to be determined due to the randomness of the content, the semantic extraction is carried out on the content item, and the content weight is determined based on the extracted semantic and a preset content semantic-content weight library; the content semantics-content weight library includes content weights corresponding to different content semantics, for example: "closed wheat while watching", content weight 20. When the input mode of the content item is based on the list selection input, determining the content weight based on a preset content weight library; the content weight library comprises the content weight of each video picture request knowing condition in the video picture request knowing condition list.
According to the embodiment of the invention, the content weight is respectively determined in different modes according to different input modes of the content item, so that the rationality is improved; in addition, a content semantic-content weight library and a content weight library are introduced, so that the determination efficiency of the content weight is improved.
Example 5
In one embodiment, the step 4: based on the viewing condition, performing request verification on the participant, including:
sequentially traversing the first target content;
during each traversal, acquiring the word length of the traversed first target content;
determining a first target value according to the character length based on a preset first target value determination rule;
sequentially traversing the second target content;
during each traversal, acquiring the character layout of the traversed second target content;
determining a second target value according to the text layout based on a preset second target value determination rule;
accumulating and calculating each first target value and each second target value to obtain a target value sum;
if the target value sum is larger than or equal to the preset target value sum threshold, the subscriber requests that the verification is not passed;
wherein the first target value determination rule includes:
determining a second viewing duration which should be generated if the user carefully views the traversed first target content based on the character length;
if the second viewing time length is shorter than the first viewing time length of the first target content traversed by the participant, acquiring a time length difference between the second viewing time length and the first viewing time length of the first target content traversed by the participant;
giving the content weight of the first target content traversed by the duration difference value to obtain a first target value;
wherein the second target value determination rule includes:
determining a second sight movement condition which is generated if the user carefully views the traversed second target content based on the text layout;
performing difference analysis on the first sight line movement condition and the second sight line movement condition when the user views the traversed second target content to obtain a difference degree;
and giving the content weight of the second target content traversed by the difference degree to obtain a second target value.
The working principle and the beneficial effects of the technical scheme are as follows:
the importance of the first target content is smaller, and the character length of the first target content is obtained; the character length is the character length when the character length is displayed in a display interface of the intelligent terminal used by the subscriber. Determining a second checking duration which is generated if the subscriber checks seriously based on the character length, and comparing the second checking duration with the first checking duration; when the second viewing duration is determined, a preset text length-viewing duration library may be queried, where the second viewing duration corresponding to different text lengths is included, for example: the text length was 12cm and the second viewing time period was 1.3 seconds. If the first checking time length is smaller than the second checking time length, determining a time length difference value, wherein the larger the time length difference value is, the higher the possibility that the subscriber does not check seriously is. Giving a content weight of a first target content with the time length difference to obtain a first target value; when giving, they are multiplied by each other.
The importance of the second target content is larger, and the text layout of the second target content is obtained; the text layout is a text layout when displayed in a display interface of the intelligent terminal used by the user, for example: the starting position and the ending position of each line of the text, several line changes and the like. Determining a second sight line movement condition which is generated if the user carefully views the traversed second target content based on the character layout; the content type of the content included in the second sight line movement situation coincides with the first sight line movement situation, for example: the moving track is that the track point slowly moves from left to right for a certain distance (see the first row), quickly moves from right to left (the first row is seen and is switched to the second row), and then slowly moves from left to right for a certain distance (see the second row); the second sight movement condition can be determined based on a neural network model, the neural network model is an artificial intelligence model which is trained to be convergent based on a large number of logic processes which are manually determined based on content character layout and determine the sight movement condition which should be generated when the viewer carefully views, and simply speaking, the logic processes are used as training samples to train the artificial intelligence model which can replace the logic processes which are manually determined based on the content character layout and determine the sight movement condition which should be generated when the viewer carefully views; this logical process is, for example: the text layout is from left to right, and the sight line movement condition to be generated is that the sight line moves from left to right; the training of the neural network model belongs to the field of the prior art, and is not described in detail. And performing difference analysis on the first sight line movement situation and the second sight line movement situation to obtain a difference degree, wherein the larger the difference degree is, the larger the difference is, the larger the possibility that the join person does not view the sight line is. Giving the content weight of the second target content with the difference degree to obtain a second target value; when giving, they are multiplied by each other.
If the sum of the target values of the first target value and the second target value is calculated in an accumulated manner and is larger than or equal to the preset target value and threshold value, the fact that the whole enrollee is not viewed seriously is indicated to be high, and the enrollee requests that the verification is not passed.
According to the embodiment of the invention, different verification modes are adopted for the first target content and the second target content, the first target value and the second target value are respectively determined, and the degree that the whole joiner is not checked seriously is determined after accumulation, so that the requirement of the joiner is verified, and the verification accuracy and comprehensiveness are improved.

The working principle and the beneficial effects of the technical scheme are as follows:
generally, when an initiator hosts a video conference based on its own video picture, there may be some important contents, such as: the teaching key points, the technical content key points and the like all need to be marked by the initiator, and the marking is stopped, so that the time is delayed. Therefore, the video image of the initiator can be marked with emphasis based on the speaking content of the initiator, and the video image is transmitted to the participant after the emphasis marking is completed, for example: the initiator says "our technical emphasis is the third bar. ", the third piece of content on the marked picture is the key point. User experience is improved, and host efficiency of the initiator is improved.

and extracting a second content semantic meaning of the speech content. A preset key mark triggering semantic library is introduced, wherein the key mark triggering semantic library comprises a third content semantic meaning for representing that key mark is needed, for example: "technical emphasis is xxx" and "xxx is lecture emphasis, etc. Matching the second content semantics with the third content semantics, and if the matching is in accordance with the third content semantics, introducing a preset key marking strategy corresponding to the matched third content semantics, wherein the key marking strategy comprises: the key frame search strategy and the key frame marking strategy are, for example: and if the third content semantic is that the emphasis is the first item, searching the first item of content in the picture, and marking the emphasis picture with the emphasis picture marking strategy that the first item is marked as the emphasis.
In the embodiment of the invention, the key mark triggering semantic library is introduced to trigger and determine whether the key mark is needed or not, so that key mark resources are reduced, and in addition, a key mark strategy is introduced to improve the marking efficiency of the key mark.
