[0002] Network live broadcast refers to a technology that anchors share live audio and video streams on the network to audiences through a network live broadcast platform. Network live broadcast is a new network industry, which embodies the characteristics of Internet openness and sharing, and enables every ordinary person to have the opportunity to show their talents on the network.

[0003] In the process of performing talents on the network live broadcast, some audiences will send virtual gifts in the live broadcast room to interact and express their affirmation of the live broadcast content, thereby enabling the anchors to create income and enabling the anchors to work at home. Especially for people in remote areas or people with limited mobility, or people who cannot normally go out to work, it has created a more convenient employment path and driven social employment.

[0004] The network live broadcast platform selects more talented anchors or encourages anchors to provide better live broadcast content, and allows two or more anchors to simultaneously live broadcast in the live broadcast room. Anchors with more talent or who can provide better live broadcast content will receive more audience support and recognition.

[0005] Currently, in the process of network live broadcast, anchors can interact in real time through the establishment of a call-in session, so that audiences who join their respective live broadcast rooms can watch the audio and video interaction content between the anchors in the live broadcast room.

[0043] Please refer to Figure 1 , Figure 1 The application scenario of the picture brightness adjustment method for live streaming and microphone connection provided in the embodiments of the present application is shown in the figure, which includes the host client 101, the server 102 and the audience client 103 provided in the embodiments of the present application. The host client 101 and the audience client 103 interact through the server 102.

[0044] The host client 101 refers to the end of sending a network live streaming video, and is usually the client used by the host (i.e., the live streaming host user) in the network live streaming.

[0045] The audience client 103 refers to the end of receiving and watching a network live streaming video, and is usually the client used by the audience (i.e., the live streaming audience user) watching the video in the network live streaming.

[0046] The hardware pointed to by the host client 101 and the audience client 103 essentially refers to a computer device, specifically, as shown in Figure 1 , it can be a smart phone, a smart interactive tablet and a personal computer, etc. The host client 101 and the audience client 103 can access the Internet through a known network access method and establish a data communication link with the server 102.

[0047] The server 102 is a service server, which can be responsible for further connecting related audio data servers, video stream servers and other servers providing related support, etc., to form a logically associated service cluster, to provide services for related terminal devices, such as the host client 101 and the audience client 103 shown in Figure 1 .

[0048] In the embodiments of the present application, the host client 101 and the audience client 103 can join the same live streaming room (i.e., live streaming channel), and the live streaming room refers to a chat room realized by Internet technology, which usually has audio and video broadcasting functions. The host user performs live streaming in the live streaming room through the host client 101, and the audience of the audience client 103 can log in to the server 102 to enter the live streaming room to watch the live streaming.

[0049] In the live room, the anchor and the audience can interact through voice, video, text and other known online interaction methods. The anchor user usually performs a program in the form of audio and video stream for the audience, and resource interaction behavior can also be generated in the interaction process, such as the audience client 103 sending virtual gifts to the anchor client 101 in the same live room. Of course, the application form of the live room is not limited to online entertainment, but can also be extended to other related scenarios, such as user pairing interaction scenarios, video conference scenarios, online teaching scenarios, product promotion and sales scenarios, and other scenarios that require similar interaction.

[0050] Specifically, the process of the audience watching live streaming is as follows: the audience can click to access the live streaming application installed on the audience client 103, and select to enter any live room, triggering the audience client 103 to load a live room interface for the audience. The live room interface includes a plurality of interaction components, which enable the audience to watch live streaming in the live room and perform various online interactions.

[0051] In the embodiments of the present application, the server 102 can also establish a mic-in session connection between the anchor clients 101 for mic-in live streaming. The mic-in session connection can be established in a random matching mode or a friend mode.

[0052] If the random matching mode is used, the server 102 will establish a mic-in session connection between a plurality of anchor clients 101 that send a mic-in live streaming request according to certain mic-in opening rules. After the mic-in session connection is established, the client in the live room can obtain audio and video stream data corresponding to a plurality of anchor identifiers, and output the audio and video stream data in the live room, so that the users (including the audience and the anchor) in the live room can simultaneously see the real-time live streaming of a plurality of anchors.

[0053] If the friend mode is used, the anchor can specify at least one friend anchor for mic-in. After the server 102 receives the mic-in confirmation information of the anchor client 101 corresponding to the at least one friend anchor, the server 102 will establish a mic-in session connection between the anchor client 101 corresponding to the anchor identifier and the anchor client 101 corresponding to the friend anchor identifier. Similarly, after the mic-in session connection is established, the users (including the audience and the anchor) in the live room can simultaneously see the real-time live streaming of a plurality of anchors.

[0054] However, when multiple anchors perform live streaming mic-in, the exposure compensation values of the video pictures set by the anchors are different, resulting in a deviation in the brightness of the mic-in picture seen by the audience. Please refer to Figure 2 , Figure 2The display schematic diagram when the picture brightness of live streaming and microphone connection is not adjusted is provided for the embodiments of the present application. The video picture brightness of each host is different, resulting in poor viewing experience of the audience and affecting the retention rate of the audience in the live streaming room. Therefore, the embodiments of the present application provide a picture brightness adjustment method for live streaming and microphone connection.

[0055] Please refer to Figure 3 , Figure 3 The flowchart of the picture brightness adjustment method for live streaming and microphone connection is provided for the first embodiment of the present application, and the method comprises the following steps:

[0056] S10: In response to a microphone connection opening request, a plurality of host identifiers are acquired, and a microphone connection session connection between a plurality of host terminals corresponding to the plurality of host identifiers is established.

[0057] Before the microphone interaction is performed, the host needs to open the live streaming first. Specifically, the host can click to access the live streaming application, enter the live streaming interface, interact with the live streaming opening control in the live streaming interface, trigger the host client to send a live streaming opening instruction to the server, the server responds to the live streaming opening instruction, and distributes live streaming room data to the host client. The host client loads the live streaming room interface according to the live streaming room data, and plays the audio stream data collected by the host client in the live streaming room. At this time, the audience can also enter the live streaming room to obtain the voice live streaming of the host.

[0058] At this time, the microphone connection opening component is loaded in the live streaming room interface, and the host can send a microphone connection opening request to the server through the microphone connection opening component to invite the host of the other live streaming room to perform microphone connection. The host can invite the host of the other live streaming room to perform microphone connection in a random matching mode, or invite the host of the other live streaming room to perform microphone connection in a friend mode.

[0059] The server responds to the microphone connection opening request, acquires a plurality of host identifiers, and establishes a microphone connection session connection between a plurality of host terminals corresponding to the plurality of host identifiers.

[0060] S20: According to the exposure compensation range of the video picture of each host terminal, the best exposure compensation value of the video picture of each host terminal is determined, and the best exposure compensation value is distributed to the corresponding host terminal; wherein the exposure compensation range is determined according to the brightness of the video picture collected by the host terminal.

[0061] The exposure compensation is an exposure control method, and by adjusting the exposure compensation value (Exposure Values, EV for short), the exposure amount of the picture can be adjusted, so as to change the brightness of the picture. Specifically, increasing the exposure compensation value, the collected video picture will become brighter. Reducing the exposure compensation value, the collected video picture will become darker. For example, EV is greater than 0, such as EV+1, EV+2.5, etc., which means that the exposure amount is increased than EV0, and the picture brightness is brighter than EV0.

[0062] The exposure compensation range refers to the value range of the exposure compensation value, that is, the interval determined by the minimum exposure compensation value and the maximum exposure compensation value.

[0063] The exposure compensation range is determined according to the brightness of the video picture collected by the anchor end. The brightness of the video picture can be input into the exposure compensation model to obtain the exposure compensation range. Alternatively, the exposure compensation range can be obtained according to a preset mapping relationship between the brightness of the video picture and the exposure compensation range. In the mapping relationship, the brightness of one video picture corresponds to a unique exposure compensation range.

[0064] In the embodiments of the present application, the brightness of the video picture of the anchor collected by each anchor end can be input into the exposure compensation model to obtain the exposure compensation range of the video picture. Alternatively, the brightness of the video picture of the anchor collected by each anchor end can be sent to the server, and the server can input the brightness of the video picture into the exposure compensation model to obtain the exposure compensation range of the video picture.

[0065] The server can take the intersection of the exposure compensation ranges of the video pictures sent by all anchor ends. If the intersection is not an empty set, the average of each exposure compensation value in the intersection is calculated, the average result is rounded, and the calculation result is taken as the optimal exposure compensation value of the video picture of each anchor end.

[0066] Alternatively, the server can take the intersection of the exposure compensation ranges of the video pictures sent by all anchor ends. If the intersection is an empty set, the server can take the union of the exposure compensation ranges of the video pictures sent by all anchor ends, calculate the average of each exposure compensation value in the union, round the average result, and take the calculation result as the optimal exposure compensation value of the video picture of each anchor end.

[0067] S30: receiving target video picture data collected by each anchor end according to the optimal exposure compensation value.

[0068] In the embodiments of the present application, each anchor end receives the optimal exposure compensation value issued by the server, and collects target video picture data according to the optimal exposure compensation value. Specifically, after the current exposure compensation value of the camera of each anchor end is controlled to be the optimal exposure compensation value, the anchor's video picture is collected again to obtain the target video picture data.

[0069] S40: according to the target video picture data sent by each anchor end, controlling the display of the live-mic live picture in the respective live room interface of the client in the live room.

[0070] Please refer to Figure 4 ,Figure 4 The display schematic diagram when the picture brightness of the live streaming co-mic is adjusted is provided in the embodiments of the present application. The co-mic live streaming picture includes the video picture of each anchor participating in the co-mic. Specifically, the target video picture data sent by each anchor end is subjected to the mixing operation to obtain the mixed video picture data, and the mixed video picture data is displayed on the live streaming room interface of each client in the live streaming room, that is, the co-mic live streaming picture is displayed.

[0071] The server can be the execution subject of the mixing operation. Specifically, after the server receives the target video picture data corresponding to each anchor identifier, the target video picture data is subjected to the mixing operation to obtain the mixed video picture data, and then the mixed video picture data is sent to the clients in the live streaming room. The clients in the live streaming room obtain the mixed video picture data and output the mixed video picture data in the live streaming room interface.

[0072] In another optional embodiment, the anchor end is the execution subject of the mixing operation. Specifically, after the server receives the target video picture data sent by each anchor end, the target video picture data corresponding to each anchor identifier is sent to the anchor end. Optionally, the server can send only the target video picture data corresponding to the anchor identifiers of other co-mic anchors to a certain anchor end, thereby reducing the data transmission amount. After the anchor end obtains the target video picture data corresponding to each anchor identifier, the target video picture data is subjected to the mixing operation to obtain the mixed video picture data, and then the mixed video picture data is sent to the clients in the live streaming room by the server. The clients in the live streaming room obtain the mixed video picture data and output the mixed video picture data in the live streaming room interface.

[0073] In other optional embodiments, the anchor end and the audience end are the execution subjects of the mixing operation. Specifically, after the server receives the target video picture data sent by each anchor end, the target video picture data corresponding to each anchor identifier is sent to the clients in the live streaming room (including the anchor end and the audience end). After the clients in the live streaming room obtain the target video picture data corresponding to each anchor identifier, the target video picture data is subjected to the mixing operation to obtain the mixed video picture data, and the mixed video picture data is output in the live streaming room interface.

[0074] In the embodiments of the present application, the execution subject of the mixing operation on the target video picture data corresponding to each anchor identifier is not limited, which can be the server, the anchor end, or the audience end.

[0075] According to the embodiment of the present application, the plurality of anchor identifiers are obtained in response to the request for starting the live-mixing, the live-mixing session connection between the plurality of anchor terminals corresponding to the plurality of anchor identifiers is established, the optimal exposure compensation value of the video picture of each anchor terminal is determined according to the exposure compensation range of the video picture of each anchor terminal, the optimal exposure compensation value is sent to the corresponding anchor terminal, wherein the exposure compensation range is determined according to the brightness of the video picture collected by the anchor terminal, the target video picture data collected by each anchor terminal according to the optimal exposure compensation value is received, and the live-mixing live picture is displayed in the live room interface of each client in the live room according to the target video picture data sent by each anchor terminal, thereby reducing the deviation of the brightness of the live-mixing picture and improving the retention rate of the audience in the live room.

[0076] In an optional embodiment, referring to Figure 5 , the step S20 of determining the optimal exposure compensation value of the video picture of each anchor terminal according to the exposure compensation range includes steps S201-S203, which are as follows:

[0077] S201: performing intersection operation on the exposure compensation range of the video picture of each anchor terminal to obtain an exposure compensation set;

[0078] S202: if the exposure compensation set is not empty, averaging all exposure compensation values in the exposure compensation set to obtain an average exposure compensation value;

[0079] S203: taking the average exposure compensation value as the optimal exposure compensation value of the video picture of each anchor terminal.

[0080] In the embodiment of the present application, each exposure compensation value in the exposure compensation range is spaced by 0.1. Taking the live-mixing between the anchor A and the anchor B as an example, if the exposure compensation range of the video picture of the anchor A is EV+3.0-EV+5.0, including the exposure compensation values EV+3.0, EV+3.1, EV+3.2, …, EV+5.0, and the exposure compensation range of the video picture of the anchor B is EV+4.0-EV+6.0, including the exposure compensation values EV+4.0, EV+4.1, EV+4.2, …, EV+6.0, then the exposure compensation set is {EV+4.0, EV+4.1, EV+4.2, …, EV+5.0}, and the average exposure compensation value is EV+4.5, which is taken as the optimal exposure compensation value of the video picture of the anchor A and the anchor B.

[0081] In an optional embodiment, if the average exposure compensation value has two decimal points, for example, the average exposure compensation value is EV+4.68, the average exposure compensation value can be rounded to keep only one decimal point to obtain EV+4.7.

[0082] By taking the average exposure compensation value as the optimal exposure compensation value of the video picture of each anchor end, the optimal exposure compensation value of the video picture of each anchor end is consistent, so that the brightness of the video picture of each anchor end is the same, which can reduce the deviation of the brightness of the live microphone picture and improve the retention rate of the live audience.

[0083] In an optional embodiment, referring to Figure 6 , the step S20 of determining the optimal exposure compensation value of the video picture of each anchor end according to the exposure compensation range includes steps S204-S207, which are as follows:

[0084] S204: If the exposure compensation set is empty, perform a set union operation on the exposure compensation range of the video picture of each anchor end to obtain a first exposure compensation set;

[0085] S205: Average all exposure compensation values in the first exposure compensation set to obtain a first average result, and perform a rounding operation on the first average result to obtain a first average exposure compensation value;

[0086] S206: Traverse the exposure compensation range of the video picture of each anchor end, and if the first average exposure compensation value is within the exposure compensation range of the video picture of the current anchor end, take the first average exposure compensation value as the optimal exposure compensation value of the video picture of the corresponding anchor end;

[0087] S207: If the first average exposure compensation value is not within the exposure compensation range of the video picture of the current anchor end, obtain the difference between each exposure compensation value in the exposure compensation range of the video picture of the current anchor end and the first average exposure compensation value, and take the exposure compensation value with the smallest difference as the optimal exposure compensation value of the video picture of the corresponding anchor end.

[0088] In the embodiments of the present application, if the exposure compensation range of the video picture of the host A is EV+3.0~EV+4.0, including the exposure compensation values EV+3.0, EV+3.1, EV+3.2, …, EV+4.0, and the exposure compensation range of the video picture of the host B is EV+6.0~EV+7.0, including the exposure compensation values EV+6.0, EV+6.1, EV+6.2, …, EV+7.0, the exposure compensation set is empty, the first exposure compensation set is {EV+3.0, EV+3.1, EV+3.2, …, EV+5.0, EV+6.0, EV+6.1, EV+6.2, …, EV+7.0}, and the first average exposure compensation value is EV+5.0. The first average exposure compensation value is neither in the exposure compensation range EV+3.0~EV+4.0 of the video picture of the host A nor in the exposure compensation range EV+6.0~EV+7.0 of the video picture of the host B, the exposure compensation value EV+4.0 in the exposure compensation range of the host A is closest to the first average exposure compensation value, that is, the difference is smallest, and the exposure compensation value EV+6.0 in the exposure compensation range of the host B is closest to the first average exposure compensation value, that is, the difference is smallest. Therefore, EV+4.0 is taken as the optimal exposure compensation value of the video picture of the host A, and EV+6.0 is taken as the optimal exposure compensation value of the video picture of the host B.

[0089] By judging whether the first average exposure compensation value is in the exposure compensation range of the video picture of the host side, the optimal exposure compensation value of the video picture of each host side is determined, so that the optimal exposure compensation values of the video pictures of each host side are the same or very small, thereby the deviation of the brightness of the mic-in picture can be reduced, and the retention rate of the live room audience can be improved.

[0090] In an optional embodiment, referring to Figure 7 , the step S201 of performing intersection operation on the exposure compensation ranges of the video pictures of each host side to obtain the exposure compensation set includes steps S2011-S2012, and the details are as follows.

[0091] S2011: in response to the mic-in exit request of at least one host side, determining the mic-in host side requesting to exit;

[0092] S2012: performing intersection operation on the exposure compensation ranges of the video pictures of the remaining host sides except the mic-in host side requesting to exit to obtain the exposure compensation set.

[0093] In the embodiment of the present application, if an anchor exits the live streaming during the live streaming, the server no longer considers the exposure compensation range of the video picture of the anchor end that exits the live streaming, and accordingly, the server re-determines the exposure compensation set according to the exposure compensation range of the video picture sent by the remaining live streaming anchor end, so as to subsequently re-determine the optimal exposure compensation value of each anchor end.
