Fig. 2 shows a flow chart of a method for filtering live video content according to another embodiment of the invention. As shown in fig. 2, the method for filtering live video content specifically includes the following steps:
step S201, receiving the video live broadcast content corresponding to the live broadcast room of the anchor broadcast sent by the anchor broadcast terminal.
This step is described with reference to step S101 in the embodiment of fig. 1, and is not described herein again.
Step S202, the installation information of the filter of at least one client entering the live broadcast room is counted to obtain the installation result of the filter.
And counting the installation information of the filter installed at the client entering the live broadcast room to obtain an installation result. Different filters comprise different algorithms, calculate from different dimensions, different data types and the like, and score the live video content. Such as different kinds of filters including a filter, B filter, C filter, D filter, E filter … …. The installation result includes, for example, information on the type of filter that has been installed, information on the number of filters installed, and the like. The type information of the installed filters may include the type of the corresponding filter installed for each client, such as client 1 installed a filter, client 2 installed B filter, etc.; the method further comprises the step of counting according to the types of the filters installed on all the clients in the live broadcast room, and the types of the filters installed in the live broadcast room comprise an A filter, a B filter, a C filter and the like. The information on the number of filters to be installed includes the number of different filters to be installed, such as a filter installed by 10 clients, B filter installed by 5 clients, and the like. Further, the installation result also includes whether the client has installed the filter, such as the client 5 does not have the filter installed, the client 1 has the a filter installed, and so on.
Step S203, determining whether the number of types of filters installed is less than the total number of types of filters, and whether there are any clients without filters on the clients entering the live broadcast room.
Counting is carried out according to the type information of the installed filters, so that the number of the types of the installed filters in the live broadcast room can be obtained, for example, 3 different types of filters including an installed filter A, a filter B and a filter C are obtained. Considering that the more the filter types are, the more accurate the scoring result is, the more the video live broadcast content can be scored from different aspects.
When the type number of the installed filters in the live broadcast room is judged to be less than the total type number of the filters, and the client entering the live broadcast room also has a client without the filter, step S204 is executed, and the filter can be installed on the client without the filter; or, when the type number of the installed filters in the live broadcast room is not less than the total number of the types of the filters, executing step S205; alternatively, it is determined that all clients entering the live broadcast room have filters installed, and step S205 is executed.
Step S204, pushing other various filters different from the types of the installed filters to the client without installing the filters so that the client can install the other various filters.
And pushing other various filters different from the types of the filters installed in the live broadcast room to the clients without installing the filters, wherein the filters installed in the live broadcast room comprise an A filter, a B filter and a C filter, the clients without installing the filters comprise a client 5, a client 7 and the like, and pushing a D filter, an E filter, an F filter and the like except the A filter, the B filter and the C filter to the clients so that the clients can install other various filters.
Further, when the number of clients without filters is less than or equal to the number of types of filters to be pushed, the clients install different types of filters respectively. If the client without the filter is the client 5, the client 7, the push D filter and the E filter, the client 5 is provided with the D filter, and the client 7 is provided with the E filter; or the client without the filter includes client 5, client 7, push D filter, E filter, F filter, client 5 installs D filter, client 7 installs F filter or client 5 installs E filter, client 7 installs F filter or client 5 installs D filter, client 7 installs E filter, and client 7 installs E filter. And when the number of the clients without the filters is larger than the number of the types of the pushed filters, the clients respectively install the same or different types of filters. If the clients without filters include client 5, client 7 and client 9, push D filter and E filter, client 5 installs D filter, client 7 installs E filter, and client 9 installs D filter. The specific client installed with which kind of filter can be randomly set, and is not limited herein.
And S205, distributing the live video content to at least one client according to the installation result so that the at least one client can score the live video content by using at least one filter which is installed in advance.
According to the installation result, when distributing the video live content to at least one client, the following different modes can be adopted:
and aiming at a plurality of clients provided with the same type of filters, selecting one or more clients from the plurality of clients as the clients for grading. For example, the client 1, the client 6 and the client 8 are all provided with a filter a, and considering that the same type of filter scores the live video content equally, the clients without the same type of filter need to score, and only the client 1 can be selected as the client for scoring. Or the client 1 and the client 6 may be selected as clients for scoring, so as to prevent the situation that the client 1 may have a problem and cannot score. And then distributing the live video content to the selected grading client side so that the grading client side can grade the live video content by using at least one pre-installed filter.
Alternatively, a plurality of clients to which the same type of filter is installed are treated as a set of scoring clients. Such as client 1, client 6, client 8, each have an a filter installed. The client 1, the client 6, and the client 8 serve as a set of scoring clients. And then carrying out grouping processing on the frame images contained in the video live content. Wherein, the number of the groups is consistent with the number of a group of grading clients. For example, the 1 st and 2 nd frame images in the 6 th frame images are grouped, the 3 rd and 4 th frame images are grouped, and the 5 th and 6 th frame images are grouped. And distributing each group of frame images after grouping processing to a group of grading clients. The 1 st, 2 nd frame image is distributed to the client terminal 1, the 3 rd, 4 th frame image is distributed to the client terminal 6, the 5 th, 6 th frame image is distributed to the client terminal 8, and each scoring client terminal scores a group of frame images by using at least one filter which is installed in advance. Client 1 scores the 1 st and 2 nd frame images with an a filter, client 6 scores the 1 st and 2 nd frame images with an a filter, and client 8 scores the 5 th and 6 th frame images with an a filter. Therefore, the scoring speed of the client can be improved, and the pressure of the client is relieved. The number of frames of the frame images included in each group may be the same or different in the specific grouping processing. When the number of clients of each group of grading clients corresponding to different types of filters is inconsistent, if 3 clients of the A filter are installed and 4 clients of the B filter are installed, in order to conveniently group frame images, 3 clients of the B filter can be selected from the clients of the B filter to be used as the grading clients of the B filter; alternatively, the frame images may be divided into different groups corresponding to different filters, 3 groups for the a filter and 4 groups for the B filter, and the groups may be distributed to corresponding clients, so that each client for scoring scores a group of frame images using at least one filter installed in advance. It should be noted that after the grouping processing, each scoring client still receives the complete live video content distributed by the server, but each scoring client only scores the frame images distributed by the grouping, but does not need to score the complete live video content.
And step S206, obtaining a second score of the video live broadcast content according to at least one first score statistic.
According to different filter types, corresponding weight parameters can be set for each filter in advance. Such as an a filter weight of 0.2, a B filter weight of 0.4, etc. Correspondingly, the weight parameter is set according to the importance of the specific filtering content of the filter, the weight parameter with high importance is higher, and the weight parameter with low importance is lower.
And receiving at least one first score returned by at least one client, and obtaining corresponding weight according to the filter type installed by the client. And accumulating the products of at least one first score and the corresponding weight parameter thereof, and calculating the average value of the accumulated results to obtain a second score of the video live broadcast content.
Step S207, determining whether the second score is lower than a preset threshold.
And determining whether to filter the live video content according to the second score, executing the step S208 if the second score is lower than a preset threshold value, otherwise, not processing the live video content, and continuously distributing the live video content to each client for watching.
And step S208, determining to filter the live video content.
And when the second score is lower than the preset threshold value, the video live broadcast content is not distributed to all the client sides of the live broadcast room any more, and the client sides cannot watch the video live broadcast content any more.
According to the live video content filtering method provided by the invention, the installation information of the filter of at least one client entering the live broadcast room is counted to obtain the installation result of the filter. And distributing the live video content to at least one client according to the installation result so that the at least one client can score the live video content by utilizing at least one filter which is installed in advance. When the video live broadcast content is distributed, one or more clients can be selected from a plurality of clients provided with the same type of filters as scoring clients, and scoring is carried out only by using the scoring clients, so that repeated scoring is avoided; or a plurality of clients with the same type of filters installed are used as a group of grading clients to group frame images contained in the live video content, and each grading client grades a group of frame images by using at least one filter installed in advance, so that the advantages of the plurality of clients are fully utilized, and the client pressure is reduced. Further, when the number of the types of the installed filters is judged to be less than the total number of the types of the filters, and when the client entering the live broadcast room has a client without the filter, other various types of filters different from the types of the installed filters can be installed at the client, so that the live broadcast content can be judged from more aspects, and an accurate score can be obtained. And after the first score is obtained, calculating to obtain a second score according to the first score and the weight parameter corresponding to the filter type. And determining whether to filter the live video content according to the level of the second score. The method and the device utilize the client side to install the filter to score the live video content, reduce the pressure borne by the server, transfer the filtering of the live video content from the server to the client side, and save the expense of the server. In addition, the invention utilizes the characteristic that a plurality of live broadcast users are watched, and different filters can be installed on a plurality of client sides, so that the plurality of different filters can respectively score the live video content, and the scoring can be more accurate.
Fig. 3 shows a functional block diagram of a live video content filtering apparatus according to an embodiment of the present invention. As shown in fig. 3, the apparatus for filtering live video content includes the following modules:
the receiving module 310 is adapted to receive the video live broadcast content sent by the anchor terminal and corresponding to the live broadcast room of the anchor.
The anchor can record the live video content by utilizing the anchor end, and simultaneously, the recorded live video content is transmitted in real time. The receiving module 310 receives the live video content sent by the anchor terminal, and marks a live broadcast room corresponding to the live video content as a live broadcast room in which the anchor is located.
And the scoring module 320 is suitable for distributing the video live content to at least one client entering the live room so that the at least one client can score the video live content by utilizing at least one pre-installed filter.
The present embodiment may pre-install a plurality of filters at a plurality of clients, wherein each client installs at least one filter. The filter types can be different, and when the filter is pre-installed at the client, the same or different filter types can be randomly installed at different clients. Each client is provided with one filter, or a plurality of filters of different types can be arranged in one client (the filters are required to be arranged by combining the equipment conditions of the client). Different filters comprise different algorithms, calculate from different dimensions, different data types and the like, and score the live video content. The size of the filter is set to be about several k, so that the client side is convenient to install. The specific installation mode is set according to the implementation condition, and is not set here.
The scoring module 320 may correspondingly distribute the live video content marked in the live broadcast room to at least one client after the at least one client enters the live broadcast room, and may perform corresponding scoring on the live video content by using at least one filter pre-installed in the client.
And the filtering module 330 is adapted to receive at least one first score returned by at least one client, and determine whether to filter the live video content according to the at least one first score.
The filtering module 330 receives at least one first score returned by at least one client, and performs corresponding processing on the live video content according to the level of the at least one first score. If at least one of the first scores is too low, the filtering module 330 performs filtering processing on the live video content, and does not continue to distribute the live video content to all the clients in the live broadcast room. Considering that the number of general users watching live broadcast is large, when the filtering module 330 receives a plurality of first scores returned by a plurality of clients, the filtering module 330 may count the plurality of first scores, for example, when the plurality of first scores are low, or calculate an average score of all the first scores, and when the average score is low, the filtering module 330 filters the live video content and does not distribute the live video content to all the clients entering the live broadcast room. The specific way of determining whether to filter the live video content is not limited herein.
According to the video live broadcast content filtering device provided by the invention, the video live broadcast content corresponding to the live broadcast room of the anchor broadcast sent by the anchor broadcast end is received; distributing the live video content to at least one client entering a live broadcast room so that the at least one client can score the live video content by utilizing at least one pre-installed filter; and receiving at least one first score returned by at least one client, and determining whether to filter the live video content according to the at least one first score. The filter is pre-installed on the client side, the client side scores the live video content by using the filter, the pressure borne by the server is reduced, the filter of the live video content is transferred to the client side from the server, and the expense of the server is saved. In addition, the invention utilizes the characteristic that a plurality of live broadcast users are watched, and different filters can be installed on a plurality of client sides, so that the plurality of different filters can respectively score the live video content, and the scoring can be more accurate.
Fig. 4 shows a functional block diagram of a live video content filtering apparatus according to another embodiment of the present invention. As shown in fig. 4, the difference from fig. 3 is that the live video content filtering apparatus further includes:
the statistical module 340 is adapted to perform statistics on the installation information of the filter of at least one client entering the live broadcast room to obtain an installation result of the filter.
The statistical module 340 counts the installation information of the filter installed at the client entering the live broadcast room, and obtains the installation result. Different filters comprise different algorithms, calculate from different dimensions, different data types and the like, and score the live video content. Such as different kinds of filters including a filter, B filter, C filter, D filter, E filter … …. The installation result includes, for example, information on the type of filter that has been installed, information on the number of filters installed, and the like. The type information of the installed filters may include the type of the corresponding filter installed for each client, such as client 1 installed a filter, client 2 installed B filter, etc.; the information of the types of the installed filters also comprises statistics according to the types of the filters installed by all the clients in the live broadcast room, and the obtained types of the filters installed in the live broadcast room comprise an A filter, a B filter, a C filter and the like. The information on the number of filters to be installed includes the number of different filters to be installed, such as a filter installed by 10 clients, B filter installed by 5 clients, and the like. Further, the installation result also includes whether the client has installed the filter, such as the client 5 does not have the filter installed, the client 1 has the a filter installed, and so on.
The pushing module 350 is adapted to perform statistics according to the type information of the installed filters, and if the type number of the installed filters is judged to be less than the total number of the types of the filters, the clients entering the live broadcast room also have clients without the installed filters; pushing other various filters different from the installed filters to the client without installing the filters so that the client can install the other various filters.
The push module 350 performs statistics according to the type information of the installed filters, so as to obtain the number of the types of the installed filters in the live broadcast room, for example, 3 different types of filters including the installed a filter, the installed B filter, and the installed C filter. Considering that the more the filter types are, the more accurate the scoring result is, the more the video live broadcast content can be scored from different aspects.
When the pushing module 350 determines that the number of types of filters installed in the live broadcast room is less than the total number of types of filters, and a client entering the live broadcast room has a client without a filter, pushing other various types of filters different from the type of filters installed in the live broadcast room to the client without a filter, and installing other various types of filters on the client without a filter; when the push module 350 determines that the number of the types of the filters installed in the live broadcast room is not less than the total number of the types of the filters, or the push module 350 determines that the clients entering the live broadcast room all have the clients with the filters installed, the filters are not pushed any more.
The pushing module 350 pushes various other types of filters different from the type of the filter installed in the live broadcast room to the client without the filter installed in the live broadcast room, for example, the filter installed in the live broadcast room includes an a filter, a B filter, and a C filter, the client without the filter installed includes a client 5, a client 7, and the like, and the pushing module 350 pushes a D filter, an E filter, an F filter, and the like, except the a filter, the B filter, and the C filter, to the clients, so that the clients can install various other types of filters.
Further, when the number of clients without filters is less than or equal to the number of types of filters to be pushed, the clients install different types of filters respectively. If the client without the filter is the client 5, the client 7, the push D filter and the E filter, the client 5 is provided with the D filter, and the client 7 is provided with the E filter; or the client without the filter includes client 5, client 7, push D filter, E filter, F filter, client 5 installs D filter, client 7 installs F filter or client 5 installs E filter, client 7 installs F filter or client 5 installs D filter, client 7 installs E filter, and client 7 installs E filter. And when the number of the clients without the filters is larger than the number of the types of the pushed filters, the clients respectively install the same or different types of filters. If the clients without filters include client 5, client 7 and client 9, push D filter and E filter, client 5 installs D filter, client 7 installs E filter, and client 9 installs D filter. The specific client installed with which kind of filter can be randomly set, and is not limited herein.
The scoring module 320 is further adapted to distribute the live video content to at least one client according to the installation result, so that the at least one client can score the live video content by using at least one pre-installed filter.
The scoring module 320 may adopt the following different manners when distributing the live video content to at least one client according to the installation result:
the scoring module 320 selects one or more clients as scoring clients from the plurality of clients installed with the same type of filter. For example, the client 1, the client 6, and the client 8 are all installed with a filter a, and considering that the same kind of filters are all the same in scoring the live video content, it is not necessary to score by using a plurality of clients installed with the same kind of filters, and the scoring module 320 may only select the client 1 as the client for scoring. Or the scoring module 320 may select the client 1 and the client 6 as scoring clients, so as to prevent the client 1 from being unable to score due to a possible problem. The scoring module 320 then distributes the live video content to the selected scoring client, so that the scoring client scores the live video content with at least one pre-installed filter.
Alternatively, the scoring module 320 may set a plurality of clients to which the same type of filter is installed as a set of scoring clients. Such as client 1, client 6, client 8, each have an a filter installed. The client 1, the client 6, and the client 8 serve as a set of scoring clients. The scoring module 320 then performs a grouping process on the frame images contained in the live video content. Wherein, the number of the groups is consistent with the number of a group of grading clients. For example, the scoring module 320 groups the 1 st and 2 nd images, the 3 rd and 4 th images, and the 5 th and 6 th images of the 6 th images. The scoring module 320 distributes the grouped frame images to a group of scoring clients. The 1 st, 2 nd frame image is distributed to the client terminal 1, the 3 rd, 4 th frame image is distributed to the client terminal 6, the 5 th, 6 th frame image is distributed to the client terminal 8, and each scoring client terminal scores a group of frame images by using at least one filter which is installed in advance. Client 1 scores the 1 st and 2 nd frame images with an a filter, client 6 scores the 1 st and 2 nd frame images with an a filter, and client 8 scores the 5 th and 6 th frame images with an a filter. Therefore, the scoring speed of the client can be improved, and the pressure of the client is relieved. The number of frames of the frame images included in each group may be the same or different in the specific grouping processing. When the number of clients of each group of clients for scoring corresponding to different types of filters is inconsistent, if 3 clients of the filter a are installed and 4 clients of the filter B are installed, in order to conveniently group frame images, the scoring module 320 can select 3 clients for scoring of the filter B from the clients of the filter B; alternatively, the scoring module 320 may divide the frame images into different groups corresponding to different filters, divide the frame images into 3 groups for the a filter and divide the frame images into 4 groups for the B filter, and distribute the groups to corresponding clients, so that each client for scoring scores a group of frame images using at least one filter installed in advance. It should be noted that after the grouping processing, each scoring client still receives the complete live video content distributed by the server, but each scoring client only scores the frame images distributed in groups, but does not need to score the complete live video content.
The weight setting module 360 is adapted to set a corresponding weight parameter for each filter in advance according to the type of each filter.
The weight setting module 360 may set a corresponding weight parameter for each filter in advance according to different filter types. Such as an a filter weight of 0.2, a B filter weight of 0.4, etc. Correspondingly, the weight parameter is set according to the importance of the specific filtering content of the filter, the weight setting module 360 with high importance sets the weight parameter to be higher, and the weight setting module 360 with low importance sets the weight parameter to be lower.
The filtering module 330 is further adapted to receive at least one first score returned by at least one client and to derive a corresponding weight according to the client-installed filter category. The filtering module 330 accumulates the product of at least one first score and the corresponding weight parameter, and calculates an average value of the accumulated result to obtain a second score of the video live content.
The filtering module 330 determines whether to filter the live video content according to the second score, and when the filtering module 330 determines that the second score is lower than the preset threshold, the live video content is no longer distributed to all the clients in the live broadcast room, and the clients cannot continuously watch the live video content. Otherwise, the filtering module 330 does not process the live video content, and continues to distribute the live video content to each client for each client to watch.
According to the live video content filtering device provided by the invention, the installation information of the filter of at least one client entering the live broadcast room is counted to obtain the installation result of the filter. And distributing the live video content to at least one client according to the installation result so that the at least one client can score the live video content by utilizing at least one filter which is installed in advance. When the video live broadcast content is distributed, one or more clients can be selected from a plurality of clients provided with the same type of filters as scoring clients, and scoring is carried out only by using the scoring clients, so that repeated scoring is avoided; or a plurality of clients with the same type of filters installed are used as a group of grading clients to group frame images contained in the live video content, and each grading client grades a group of frame images by using at least one filter installed in advance, so that the advantages of the plurality of clients are fully utilized, and the client pressure is reduced. Further, when the number of the types of the installed filters is judged to be less than the total number of the types of the filters, and when the client entering the live broadcast room has a client without the filter, other various types of filters different from the types of the installed filters can be installed at the client, so that the live broadcast content can be judged from more aspects, and an accurate score can be obtained. And after the first score is obtained, calculating to obtain a second score according to the first score and the weight parameter corresponding to the filter type. And determining whether to filter the live video content according to the level of the second score. The method and the device utilize the client side to install the filter to score the live video content, reduce the pressure borne by the server, transfer the filtering of the live video content from the server to the client side, and save the expense of the server. In addition, the invention utilizes the characteristic that a plurality of live broadcast users are watched, and different filters can be installed on a plurality of client sides, so that the plurality of different filters can respectively score the live video content, and the scoring can be more accurate.
The application also provides a non-volatile computer storage medium, wherein the computer storage medium stores at least one executable instruction, and the computer executable instruction can execute the video live content filtering method in any method embodiment.
