In one possible implementation manner, the determining the live sequence of each live product according to the product positioning includes:
determining a main pushing product and a drainage product in the at least one live product to be live broadcast according to the product positioning; obtaining the product heat and/or the product sales of each main pushing product; dividing the main pushing product into a plurality of sales grades according to the product heat and/or the product sales volume; acquiring predicted live broadcast time length; dividing the predicted live time length into a plurality of live time periods according to the predicted live time length and the plurality of sales grades; determining a live broadcast period of each main push product according to the sales grade corresponding to each main push product, wherein each live broadcast period corresponds to at least one main push product, and the sales grades of a plurality of main push products corresponding to the same live broadcast period are different; generating a reference live broadcast sequence according to the live broadcast period of each main push product; and generating the live broadcast sequence of each live broadcast product according to the drainage product and the reference live broadcast sequence.
The server presets a plurality of intervals divided according to the product heat and/or the product sales volume in advance, and divides the main pushing products falling into different interval thresholds into a plurality of sales grades according to the intervals, wherein each interval threshold corresponds to one sales grade.
For example, if three intervals are preset in advance by the server, the product heat or the product sales volume is less than or equal to 1 ten thousand and is a first interval, the product heat or the product sales volume is greater than 1 ten thousand and less than or equal to 5 ten thousand and is a second interval, the product heat or the product sales volume is greater than 5 ten thousand and is a third interval, the main pushing products of the first interval are products 1 and 2, the main pushing products of the second interval are products 3 and 4, the main pushing products of the third interval are products 5 and 6, the predicted live time length of the electronic device is 90 minutes at this time, the live time length is divided into a plurality of time periods according to the three intervals on average, each corresponding live time period is 30 minutes, one sales product serving as the time period is randomly extracted from the main pushing products in sales grades corresponding to the three intervals, the first direct time period is randomly extracted from the three sales grades to the products 1,3 and5 respectively, and the order of sales orders of different main pushing products, namely, the reference order is first product 1 and then the live time period is 3. When few live broadcast products exist and the main push products in all sales grades cannot be met in each live broadcast period, the main push products in more sales grades are preferentially ensured to be contained in the later period.
In this example, compared with the existing live video generation scheme, the server of the digital live video system divides products into different sales grades according to the sales volume and/or the product heat of the products, and then each live time period of the live scenario contains products with different sales grades, so that the live broadcasting room can be ensured to sell products with higher sales volume in different live time periods, and accordingly higher heat is maintained, and live broadcasting efficiency and conversion rate are improved.
In a possible implementation manner, the generating the live sequence of each live product according to the drainage product and the reference live sequence includes: determining the product type of each live broadcast product according to the product information of each live broadcast product; marking each drainage product according to the product type to obtain at least one piece of marking information corresponding to each drainage product, wherein the marking information is used for indicating a main pushing product associated with each drainage product;
wherein, live broadcast product includes owner pushes away product and drainage product, and every owner pushes away the product and all has at least one drainage product, and drainage product is used for arranging to sell before the owner pushes away the product and does not push away the product accumulation people's flow.
Referring to fig. 3, fig. 3 is a flowchart of the following operations performed on each of the drainage products according to the embodiment of the present application, and as shown in fig. 3, the following operations are performed on each of the drainage products:
Determining whether a plurality of marks correspond to the current drainage product; if the current drainage product is one, determining that the playing period of the current drainage product is the playing period of the main pushing product indicated by the mark corresponding to the drainage product, and sequencing the playing period of the main pushing product indicated by the mark; if the number of the current drainage products is multiple, determining that the current drainage products are target drainage products, and determining the playing time period of the current drainage products according to the number of the products corresponding to the playing time period of the main pushing products indicated by the marks corresponding to the target drainage products; determining the next drainage product as the current drainage product until the playing time period of all the drainage products is determined; and generating the live broadcast sequence of each live broadcast product according to the playing time periods of all the drainage products and the reference live broadcast sequence.
It can be seen that, in this example, compared to the existing live video generation scheme, the digital live system is beneficial to maintaining the flow of the live broadcasting room through the drainage products related to the main push products by determining the drainage products corresponding to each main push product according to the product information of each live broadcast product, so as to improve the live broadcasting benefit.
In a possible implementation manner, the determining the playing period of the current drainage product according to the number of products corresponding to the playing period of the main pushing product indicated by the mark corresponding to the target drainage product includes: determining the number of live broadcast products corresponding to each playing period; determining the number of the target drainage products; determining the maximum receivable number for receiving the broadcasting of the live broadcast product in each broadcasting period according to the number of the target drainage products and the number of the live broadcast products corresponding to each broadcasting period; the following operations are performed for each target drainage product: determining a plurality of reference main stream products indicated by marks corresponding to the current target drainage product; determining a reference playing period corresponding to each reference mainstream product in the plurality of reference mainstream products; determining an alternative playing period which can accommodate the playing of the drainage product in the reference playing period according to the maximum accommodating quantity of the reference playing period; determining the alternative playing time period with the least quantity of the corresponding live broadcast products in the alternative playing time periods as a target playing time period; determining the playing time interval of the current drainage product as the target playing time interval, and changing the maximum accommodating quantity of the target playing time interval; and determining the next target drainage product as the current drainage product until the playing period of each target drainage product is determined.
When determining the drainage product associated with the main pushing product, the method first judges according to the product type information in the product information of each live broadcasting product, for example, if the main pushing product A, the drainage product B and the drainage product C belong to kitchen supplies, the drainage product B and the drainage product C are the drainage products corresponding to the main pushing product A.
If a plurality of direct broadcast products corresponding to the main push products exist, the operation is carried out on the direct broadcast products so that the overlapped direct broadcast products are only related to one main push product.
Specifically, whether the reference drainage products corresponding to each main pushing product are overlapped or not is determined, if so, whether the main pushing product with the overlapped drainage products is only corresponding to one reference drainage product is determined, if so, the reference drainage product is determined to be the target drainage product of the main pushing product, and the reference drainage product is deleted from the reference drainage products corresponding to other main pushing products. And the like, wherein a plurality of drainage products respectively correspond to the main pushing products corresponding to the reference drainage products which are overlapped at last.
Illustratively, the drainage products corresponding to the main pushing product a include a drainage product 1, a drainage product 2 and a drainage product 3, the drainage products corresponding to the main pushing product B include a drainage product 1, a drainage product 3, a drainage product 4 and a drainage product 5, the drainage products corresponding to the main pushing product C include a drainage product 3, the drainage products 1 and 3 appear in the drainage products corresponding to the main pushing products, at this time, regarding the drainage product 3, the number of live broadcast products corresponding to the main pushing product C in the alternative playing period is the minimum, regarding the drainage product 1, the number of live broadcast products corresponding to the main pushing product C in the alternative playing period is the minimum, the drainage product 1 is the drainage product corresponding to the main pushing product a, the drainage products 1 and 2 corresponding to the main pushing product a are finally obtained, the drainage products corresponding to the main pushing product B correspond to the drainage products 4 and 5, and the main pushing product C corresponds to the drainage product 3.
Therefore, in this example, compared with the existing live video generation scheme, the server of the digital human live broadcast system can ensure that each drainage product only appears once in one live broadcast process by continuously removing the overlapped drainage products in the plurality of main push products, so that user loss caused by repeatedly playing the same commodity in the generated live video is avoided, flow and heat between live broadcast rooms are ensured, and live broadcast efficiency is improved.
In one possible implementation manner, the generating a reference live scenario according to the product basic information of each live product and the scenario frame includes: determining the product type of each live broadcast product according to the product basic information; determining a description template of each live broadcast product according to the product type; acquiring a live broadcast universal conversation corresponding to each product type; generating an initial live script through the description template according to the product type of each product; and generating a reference live scenario according to the live universal conversation and the initial live scenario.
One or more description templates of the live broadcast product are obtained according to the product type, and then one of the description templates is selected to be filled in the basic information of the live broadcast product to be live broadcast, so that an initial live broadcast scenario is obtained.
Illustratively, the product price portion text in one description template of the filled-in scenario frame is: in the following, a total of 10 cans, one 6 cans and one 8 cans of sea buckthorn juice, 68 pieces of money, are described. When imitation is performed, information can be filled in by referring to the sentence pattern, wherein the reference sentence pattern is as follows: in the template text, A is filled in the name of the live broadcast product to be directly broadcast, B is filled in the price of the live broadcast product to be directly broadcast, C is filled in the specification of the live broadcast product to be directly broadcast, and D is filled in the unit price of the live broadcast product to be directly broadcast, so that the reference live broadcast script is completed.
After the initial live scenario is obtained, the initial live scenario can be improved by inserting some live commonly used conversations in different stages of the initial live scenario.
In this example, compared with the existing live video generation scheme, the server of the digital human live broadcast system generates the live scenario through the product basic information and the description template and improves the live scenario by using the live universal phone, so that the efficiency and the accuracy of the generation of the live scenario can be ensured.
In one possible implementation manner, before the generating the reference live scenario according to the live general speaking and the initial live scenario, the method further includes: searching in a preset website according to the product name of each live broadcast product to obtain propaganda content corresponding to each product; determining propaganda emphasis of each live broadcast product according to the propaganda content; acquiring a target propaganda text corresponding to the propaganda key point; and the initial live broadcast script is moistened according to the target propaganda text.
Specifically, acquiring the propaganda content includes searching in the product official network by taking the brand name and the product as keywords, or opening a sales page of the product in a sales platform, and extracting text from a product introduction page of the sales page to obtain the propaganda content. Or sending data request information to the user, and uploading propaganda text of the product or linking the propaganda text by the user.
The propaganda emphasis is determined according to propaganda content of each live product, for example, the propaganda emphasis can be a research and development process of the product, a use experience of the product or after-sales service of the product.
It can be seen that, in this example, compared with the existing live video generation scheme, the server of the digital live system obtains the propaganda content of each product through inquiry and determines propaganda emphasis, so as to moisten the initial live scenario, which is favorable for better grasping the propaganda emphasis of the product of the reference live scenario generated later, effectively attracts attention of users, and improves the benefit of live broadcasting.
In one possible implementation manner, the rendering the initial live scenario according to the target advertisement text includes: dividing the scenario content of the initial live scenario into first scenario content and second scenario content, wherein the first scenario content is scenario content with higher propaganda key relevance than a preset value with the target propaganda text, and the second scenario content is scenario content except the first scenario content in the scenario content of the initial live scenario; replacing the first script content with the target propaganda text to obtain target first script content; performing spoken language modification on the content which is not related to the transcript content of the initial live broadcast transcript and has the transcript content association degree higher than a preset value in the propaganda key point to obtain target second transcript content; and generating an initial live broadcast scenario after the color rendering according to the target first scenario content and the target second scenario content.
The method comprises the steps of performing sentence breaking on an initial live script through punctuation marks, and comparing the relevancy of each sentence with the propaganda key point of a target propaganda text, wherein the relevancy is higher than a preset value and is the content of a first script.
The preset value can be modified at the server to adjust the association degree of the first script content and the propaganda key point of the target propaganda text.
If the association degree of a certain propaganda key point of the propaganda text in the initial live broadcast script is not higher than a preset value, carrying out text analysis on the propaganda key point, generating a spoken text, and adding the spoken text into the initial live broadcast script. For example, if the scenario content of the initial live scenario has A, B, C and D, the propaganda emphasis has emphasis 1 and emphasis 2, at this time, the association degree between A, C and the emphasis 1 in the scenario content is higher than a preset value, the association degree between A, B, C and D and the emphasis 2 are both lower than the preset value, at this time, the first scenario content is A, C, the second scenario content is B, D, the first scenario content is replaced by the target propaganda text, and at the same time, the emphasis 2 is subjected to spoken modification to obtain the target second scenario content, and then the target second scenario content is added into the scenario content of the initial live scenario to obtain the initial live scenario after the color is moistened.
It can be seen that, in this example, compared with the existing live video generation scheme, the server of the digital live system generates the target first scenario and the target second scenario by comparing the initial live scenario and the propaganda key, so as to moisten the initial live scenario, and the moistened live scenario can more easily highlight the propaganda key of the live product to be live, thereby being beneficial to increasing the attention of the live product to be live and improving the live efficiency and conversion rate.
