[0019] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

[0020] It should be noted that the title of any section / subsection provided herein is not restrictive. Various embodiments are described throughout this document, and any type of embodiment can be included under any section / subsection. In addition, the embodiments described in any section / subsection can be combined with any other embodiments described in the same section / subsection and / or different section / subsections in any manner.

[0021] In the description of the embodiments of the present disclosure, the term "comprising" and its like should be understood as an open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". There may also be other explicit and implicit definitions hereinafter. Terms such as "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions hereinafter.

[0022] The embodiments of the present disclosure may involve the user's data, data acquisition and / or use, etc. These aspects all comply with the corresponding laws, regulations and related provisions. In the embodiments of the present disclosure, the collection, acquisition, processing, processing, forwarding, use, etc. of all data are carried out on the premise that the user is aware and confirms. Correspondingly, when implementing the embodiments of the present disclosure, the type, scope of use, usage scenario, etc. of the data or information that may be involved should be informed to the user and the user's authorization should be obtained through appropriate means according to the relevant laws and regulations. The specific informing and / or authorization methods may vary according to the actual situation and application scenarios, and the scope of the present disclosure is not limited in this regard.

[0023] In the solutions of this specification and embodiments, if personal information processing is involved, it will be processed on the premise of having a legal basis (such as obtaining the consent of the personal information subject, or being necessary for performing a contract, etc.), and will only be processed within the specified or agreed scope. The user's refusal to process personal information other than the necessary information required for the basic functions will not affect the user's use of the basic functions.

[0024] Currently, the number of live users who can participate in the live task mode is limited, unable to meet the needs of different numbers of live users to perform tasks together. Moreover, due to the relatively single current live tasks and mechanisms, it is unable to meet the diverse interaction needs between the host and the audience.

[0025] Embodiments of the present disclosure propose a solution for live streaming. According to this solution, a live interface associated with a first interaction event is presented. The first interaction event is associated with multiple live users and includes multiple event stages. A first component associated with the first interaction event is presented in the live interface. The first component presents a first element corresponding to a first live user. The first live user corresponds to the live interface, and the display position of the first element in the first component is determined based on the first interaction information of the first live user in the first interaction event. And based on the current event stage of the multiple event stages, the first component is divided into multiple sub-regions, where the positional relationship between the first element and the multiple sub-regions is used to characterize the event state of the first live user in the current event stage, and the division of the multiple sub-regions changes with the switching of the event stages.

[0026] Based on such a method, embodiments of the present disclosure can allow multiple live users to participate in the live event, meet the needs of different numbers of live users through multiple event stages, improve the interaction efficiency of the live event through the interaction operations between the audience and the live users, not only enhance the confrontation among multiple live users during the live process, but also enhance the interaction between the live users and the audience.

[0027] Example environment

[0028] Figure 1 A schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented is shown. As Figure 1 shown, the example environment 100 may include a terminal device 110.

[0029] In this example environment 100, the terminal device 110 may run an application 120 for providing and watching live streams.

[0035] It should be understood that the structures and functions of the various elements in the environment 100 are described only for exemplary purposes, without implying any limitation on the scope of the present disclosure.

[0036] Various example implementations of the present disclosure will be described in detail below.

[0037] Example process

[0038] The following will refer to Figures 2A to 6D to describe an example interaction process according to an embodiment of the present disclosure. Figures 2A to 6D Example interfaces 200A to 600D for a live event according to some embodiments of the present disclosure are shown. Such example interfaces may be implemented by a suitable terminal device 110 or a combination of terminal devices 110 (e.g., Figure 1 the terminal device 110, the server 130, or a combination of one or more of these devices) in

[0039] In some embodiments, the terminal device 110 may present an interface 200A associated with a live event as shown in Figure 2A . The live event may be an interactive event joined by at least one participant during the live broadcast in a pre - defined live broadcast room. As an example, the live event may be a host's live broadcast, or a co - hosting event in the live broadcast room, a competition event in the live broadcast room, etc. Such at least one participant may include live users, may also include multiple live users, and may also include live users and non - live users (such as guest users), etc. In some embodiments, the live event may correspond to any suitable type of interactive activity, such as a singing - type interactive activity, a game - type interactive activity, etc., which will not be elaborated here.

[0040] In some embodiments, for example, the live event may be an event in which, during the live broadcasts of multiple hosts, according to the interaction situation between different hosts and the audience, hosts are gradually screened to enter the next stage. The live event includes a first interactive event, a second interactive event, and a third interactive event. During each interactive event, some hosts are not allowed to enter the next stage according to different strategies. In chronological order, the order of occurrence of the events is the second interactive event, the first interactive event, and the third interactive event. In the embodiments of the present disclosure, the second interactive event is referred to as the first stage, the first interactive event is referred to as the second stage, and the third interactive event is referred to as the third stage.

[0041] In some embodiments, in the first stage, it is determined whether a host is allowed to enter the next stage according to the audience's gift - giving behavior or prop - using behavior. Conditions for a host to be allowed to enter the next stage may be set in the first stage. For example, the condition for a host to be allowed to enter the next stage may be set as: the host can enter the next stage only if the host receives 150 fireworks gifts, 150 butterfly gifts, and 150 balloon gifts within 20 minutes. This condition can be adjusted according to actual applications and will not be elaborated here.

[0042] Refer to Figure 2A, which is the interface display situation on the host side in the first stage. This interface includes three components 205, 206, and 207, and each component corresponds to a specific gift. For example, component 205 corresponds to a fireworks gift, component 206 corresponds to a butterfly gift, and component 207 corresponds to a balloon gift. When the audience sends the corresponding gift to the host, the style of the component will change accordingly. For example, the component 205 in Figure 2A is updated to the component 208 in Figure 2B . This change process is the process of lighting up the gift.

[0043] In some embodiments, the gifts corresponding to the components in the first stage are special gifts, that is, the audience must send the specified special gift to help the host enter the next stage. If the audience sends ordinary gifts, they cannot help the host enter the next stage. And the gifts can be adjusted according to the actual situation, which is not limited here. In addition, multiple special gifts can be set, but it is not necessary to display all of them on the interface. The components corresponding to the corresponding gifts can be selectively displayed according to the situation of the host. For example, 5 special gifts can be set, and 3 of them can be selected from the 5 special gifts to be displayed on the host's interface according to the host's level, classification, etc.

[0044] Moreover, each component includes the information of "0 / 3", indicating that the lighting process of each gift includes three steps. For example, it can be preset that the gift-giving quantity reaches 50 to change the style of the component. Then, if the host receives 50 fireworks gifts from the audience, the component 205 in Figure 2A can be updated to the component 208 in Figure 2B . If the host receives 150 fireworks gifts from the audience, it means that the host has received enough fireworks gifts, and the component can be further updated to the component 209 in Figure 2C , and "lit" is displayed in the component. At this time, it means that the host has obtained enough fireworks gifts. When the host obtains enough fireworks gifts, the gift logo displayed in the component 209 in Figure 2C can also be enlarged and moved to the middle of the component 209, and at the same time, the text of "lit" is hidden to inform the host and the audience that the host has collected enough fireworks gifts.

[0045] If the host meets the conditions for allowing entry into the next stage within the preset time, that is, the interface of Figure 2D is displayed, and "success" is displayed on the interface. Correspondingly, if the host does not meet the conditions for allowing entry into the next stage within the preset time, that is, the interface of Figure 2F is displayed, and "failure" is displayed on the interface. In addition, an animation of success or an animation of failure can also be displayed on the interface to increase the fun.

[0046] In some embodiments, refer to Figure 2A, the control 201 in the interface is used to display information related to the host, such as name, avatar, etc. The control 202 in the interface is used to display information of other hosts participating in the live event, such as name, avatar, etc. The control 202 in the interface is used to display the number of hosts participating in the live event. The control 204 in the interface is used to show the host the specific situation of the audience giving gifts. The "09:52" in the interface shows the remaining time until the end of the first stage. Additionally, refer to Figure 2B , the interface includes "66 people have lit up", indicating that currently 66 hosts meet the conditions to be allowed to enter the next stage.

[0047] In some embodiments, refer to Figure 2E , when there is still one minute or 30 seconds left until the end of the first stage, "Entering countdown" can also be displayed on the interface to prompt the host and the audience that the current stage is about to end. Additionally, the time information can be highlighted in different styles, such as adding a red background to the time "00:52". The duration of this countdown can be adjusted according to the actual situation and will not be elaborated here.

[0048] In some embodiments, on the host side, if the host triggers Figure 2A the control 204, then an interface as shown in Figure 5A can be displayed. In this interface, the current live situation can be understood through the component 501. "Collect gifts to clear the level within 20 minutes" indicates that the condition for allowing entry into the next stage in the first stage is to collect gifts within 20 minutes. "94 players have lit up" indicates that currently 94 hosts have met the conditions to be allowed to enter the next stage. The component 502 shows the situation of the host, such as success or failure, etc. The control 503 is used to show the host the strategy. When the host triggers the control 503, the strategy for entering the next stage can be displayed for the host. On the audience side, if the audience triggers Figure 2A the control 204, then an interface as shown in Figure 5B can be displayed, and the control 504 can be directly used to boost the host, with low understanding cost and being simple and convenient.

[0049] In some embodiments, in the second stage, whether the host is allowed to enter the next stage is determined according to the interaction behavior of the audience. This interaction behavior can be a gift-giving behavior, a like behavior, a prop-using behavior, etc. In the second stage, the conditions for the host to be allowed to enter the next stage can be set. For example, it can be set that within 5 minutes, multiple hosts are ranked according to the interaction situation between the audience and the host, and the top 8 hosts are allowed to enter the next stage, while the remaining hosts are not allowed to enter the next stage. The conditions for allowing entry into the next stage can be adjusted according to the actual application and will not be elaborated here.

[0050] In some embodiments, the second stage can also be divided into multiple event stages. For example, an event stage can be set to 30 seconds, and the second stage thus includes 10 event stages. It can be set that the maximum remaining number of people in the first event stage is 43, in the second event stage is 40, in the third event stage is 37, and so on, until the last 8 streamers are allowed to enter the next stage.

[0051] For example, if it is set that the maximum remaining number of people in the first event stage is 43 and in the second event stage is 40, then when the 30 - second settlement of the first event stage occurs, if a streamer is among the top 43, they can be allowed to enter the next stage; otherwise, they are not allowed to enter the next stage. After the first event stage ends, streamers who did not enter the top 43 are not allowed to enter the second event stage, and the top 43 streamers are allowed to enter the second event stage. Then when the 30 - second settlement of the second event stage occurs, if a streamer is among the top 40, they can be allowed to enter the third event stage; otherwise, they are not allowed to enter the third event stage, and the top 40 streamers enter the third event stage, and so on.

[0052] Reference Figure 3B , the figure includes a progress bar component. The progress bar is divided into a first sub - region 301 and a second sub - region 302. The first element is the image identifier of the first live user, such as an avatar or a special identifier, etc. For example, if it is set that the maximum remaining number of people in the first event stage is 43, then reference Figure 3B , if a streamer enters the top 43, the streamer's avatar is displayed in the first sub - region 301; reference Figure 3C , if a streamer does not enter the top 43, the streamer's avatar is displayed in the second sub - region 302. Additionally, streamers who are not allowed to enter the next stage can be displayed in the area 303 of the interface, such as "xxx is unqualified", etc.

[0053] In some embodiments, if it is set that the maximum remaining number of people in the first event stage is 43, reference Figure 3B , the avatars of streamers who did not enter the top 43 can be displayed in the second sub - region 302, and it can also be limited to display at most two streamer avatars, which will not be elaborated here. Reference Figure 3C , if a streamer does not enter the top 43, the avatars of other streamers can be not displayed, and "You enter the elimination area" can be displayed so that the streamer can clearly understand the current dangerous state at a glance.

[0054] During the entire second stage, as the event stages change, fewer and fewer streamers are allowed to enter the next stage, and more and more streamers are not allowed to enter the next stage, thus continuously enhancing the competitiveness of the live broadcast. For example, reference Figures 3A to 3B, the area of ​​the second sub-area 302 becomes larger and larger, and the area of ​​the first sub-area 301 becomes smaller and smaller. Specifically, for example, if the maximum number of remaining people is set to 43 in the first event stage and the maximum number of remaining people is set to 40 in the second event stage, then the area of ​​the second sub-area 302 in the second event stage is larger than the area of ​​the second sub-area 302 in the first event stage, and the area of ​​the first sub-area 301 in the second event stage is smaller than the area of ​​the first sub-area 301 in the first event stage. In addition, it is also possible that no anchor is prohibited from entering the next stage in a certain event stage, then the area of ​​the second sub-area 302 and the area of ​​the first sub-area 301 will not change in the next event stage.

[0055] In some embodiments, reference Figure 3D If the anchor is in the top 8 after 5 minutes, it will display "Success". Figure 3F If the anchor is not allowed to enter the next stage within 5 minutes, or the anchor is not in the top 8, "failure" will be displayed. In addition, you can also display success animation or failure animation on the interface to increase the fun. Figure 3E , and when there is one minute or 30 seconds left before the end of the second stage, "Entering Countdown" will be displayed on the interface. The countdown duration can be adjusted according to actual conditions, which will not be elaborated here.

[0056] In some embodiments, on the host side, if the host triggers Figure 3B In the control 304, the following can be displayed: Figure 6A In the interface shown, the current live broadcast status can be understood through the progress bar 601, and the progress bar 601 also includes a first sub-area and a second sub-area, the first sub-area is located on the left side of the progress bar, and the second sub-area is located on the right side of the progress bar. Figure 6A If the anchor's avatar is above the first sub-area, it means that the anchor is in the ranking that allows him to enter the next stage; refer to Figure 6B ,If the anchor’s avatar is above the second sub-area, it means that the anchor is in a ranking that is not allowed to enter the next stage.

[0057] In some embodiments, a certain score can be given to each anchor based on the interaction between the audience and the anchor, such as 100 gifts or 3,000 likes can increase a score for the anchor. Figure 6A Component 602 in , if the anchor is in the first sub-area, then "Leading xx" is displayed; Figure 6B If the anchor is in the second sub-area, it will display "behind xx". Figure 6C If the host does not allow the next stage, the message "Stop at the second stage" can be displayed. In addition, on the audience side, if the audience triggers Figure 3AFor the central control component 304, an interface as shown in Figure 6D can be displayed. This interface includes a control 605 "Boost the Anchor". If the viewer triggers the control 605, they can directly like or send gifts to the anchor, thus reducing the viewer's understanding cost.

[0058] In some embodiments, the third stage is to conduct a confrontation between the anchors based on the interaction behaviors of the viewers, and determine whether the anchor is allowed to enter the next stage according to the confrontation result. The interaction behaviors can be gift-giving behaviors, like behaviors, prop-using behaviors, etc. The third stage can include multiple event stages, and each event stage is in the form of a confrontation between two anchors. For example, if a total of 8 anchors enter the third stage, then in the first event stage, first divide the 8 anchors into 4 groups, with two anchors in each group, and then conduct a confrontation between the two anchors according to the interaction behaviors of the viewers. The 4 winning anchors can enter the second event stage. In the second event stage, divide the 4 anchors into 2 groups, with two anchors in each group, and then conduct a confrontation between the two anchors according to the interaction behaviors of the viewers. The 2 winning anchors can enter the third event stage. In the third event stage, conduct a confrontation between the two anchors according to the interaction behaviors of the viewers, and the winning anchor is the winner.

[0059] In some embodiments, corresponding scores can be assigned to the anchors according to the interaction behaviors of the viewers. Referring to Figure 4A , the live broadcast interface includes a component 401, and in this component, the avatars of the two sides in the confrontation and the scores obtained by the two sides in the confrontation will be displayed. It can also be set that the avatar on the left is the avatar of the current anchor. If the score obtained by the current anchor exceeds that of the other anchor, referring to Figure 4B , the avatars of both sides can be moved left and right according to the score situation of both sides, and "Leading" can be marked at the avatar of the anchor with the higher score.

[0060] In some embodiments, referring to Figure 4C , if the anchor wins, a winning logo can be displayed at the position of the anchor's avatar. Conversely, referring to Figure 4D , if the anchor lags behind the other anchor, a lagging logo can be displayed at the position of the anchor's avatar. After the end of the third preset duration, referring to Figure 4E , a logo of "Victory" or "Defeat" can be displayed at the positions of the anchor's avatar and the other anchor's avatar.

[0061] Based on such a method, the embodiments of the present disclosure can allow multiple live broadcast users to participate in the live broadcast event, meet the needs of different numbers of live broadcast users through multiple event stages, promote the competition among multiple live broadcast users through the interaction operations between the viewers and the live broadcast users, not only enhance the confrontation among multiple live broadcast users during the live broadcast process, but also enhance the interactivity between the live broadcast users and the viewers.

[0062] Example process

[0063] Figure 7 shows a flowchart of a process 700 for live streaming according to some embodiments of the present disclosure. The process 700 may be implemented at the terminal device 110. Refer to the following Figure 1 to describe the process 700.

[0064] In some embodiments, the terminal device 110 presents, in the live streaming interface, a second component associated with a second interaction event, and the second component indicates an interaction status associated with multiple interaction resources during the second interaction event. For example, the second interaction event is the first stage. Refer to Figure 2A which is the live streaming interface corresponding to the first stage. In the first stage, the audience needs to send special gifts to the anchor, and the special gift is the interaction resource. Additionally, the interaction resource can also be props, etc., which are not limited here. The second component is components 205, 206, and 207 in the interface, and each component corresponds to a special gift. Since in the first stage, as long as the anchor completes the corresponding tasks, they can enter the next stage, multiple anchors can perform tasks simultaneously, thus avoiding the problem of limited number of anchors participating in the tasks.

[0065] In some embodiments, the second condition indicates that the number of interaction events associated with the interaction resources reaches a threshold during the second interaction event. The second condition can be the clearance condition for the first stage. For example, the second condition can be to collect 150 fireworks gifts, 150 butterfly gifts, and 150 balloon gifts within 20 minutes. In this way, the audience can help the anchor enter the next stage during the interaction with the anchor, enhancing the interactivity of the live streaming event.

[0066] In some embodiments, the terminal device 110 presents, in the second component, multiple indication elements corresponding to multiple interaction resources, where the multiple elements indicate the number of interaction operations respectively corresponding to the multiple interaction resources. For example, refer to Figure 2A , the second component is components 205, 206, and 207 in the interface, and each component corresponds to a special gift. Component 205 shows the situation of the audience sending fireworks gifts to the anchor, component 206 shows the situation of the audience sending butterfly gifts to the anchor, and component 207 shows the situation of the audience sending balloon gifts to the anchor.

[0067] In some embodiments, the terminal device 110 updates the display style of the target indication element corresponding to the target interaction resource among the multiple indication elements in response to a target interaction operation associated with the target interaction resource. For example, updating the display style is the process of lighting up the gift. Refer to Figure 2A, each component is labeled "0 / 3", indicating that lighting each type of gift requires three steps. It can be preset that the number of gifts given reaches 50 to change one-third of the lit gifts. Then, if the host receives 50 fireworks gifts from the audience, Figure 2A the component 205 in Figure 2B can be updated to the component 208 in Figure 2C . If the host receives 150 fireworks gifts from the audience, it means the host has received enough fireworks gifts, and the component can be further updated to the component 209 in

[0068] and "lit" is displayed in the component. At this time, it means the host has obtained enough fireworks gifts. In this way, the current task execution status can be more clearly shown to the host and the audience, thereby reducing the understanding cost of the live broadcast and attracting more hosts and audiences to join.

[0069] In some embodiments, the terminal device 110 presents a first component associated with the first interaction event in response to the third interaction information of the first live party in the second interaction event of the live event satisfying the second condition. The live event includes at least the first interaction event and the second interaction event. For example, if the host has lit all the gifts within 20 minutes, it means the host can enter the second stage.

[0070] In some embodiments, the terminal device 110 presents an information control associated with the first interaction event in the live interface, and the information control is configured to present the status information of the first live user in the first interaction event.

[0070] In some embodiments, the terminal device 110 presents a viewing panel associated with the first interaction event in response to the triggering of the information display control. For example, referring to Figure 2A , when the host triggers the information display control 204, it can jump to the viewing panel in Figure 5A to view the status information of the current live broadcast. In this way, it is convenient for the host and the audience to view the live broadcast situation in real time, and through the components in the viewing panel, the host can learn the method to enter the next stage, and the audience can also simply and timely assist the host.

[0071] In block 710, the terminal device 110 presents a live interface associated with the first interaction event.

[0072] The first interaction event is the second stage. Referring to Figure 3B is the live interface corresponding to the second stage. In the second stage, all the hosts who enter the second stage need to be ranked according to the gifts given or likes from the audience to the host, and the hosts ranked at the top are allowed to enter the next level.

[0073] In some embodiments, the first interaction event is associated with multiple live users, and the first interaction event includes multiple event phases. For example, multiple hosts can enter the second phase, and the second phase can be divided into multiple event phases. It can be set that the maximum remaining number of people in the first event phase is 43, the maximum remaining number of people in the second event phase is 40, the maximum remaining number of people in the third event phase is 37, and so on, until the last 8 hosts enter the third phase. In this way, the needs of hosts with different numbers can be met. If the number of hosts is small, the number of event phases can be reduced to quickly screen out the top-ranked hosts; if the number of hosts is large, the number of event phases can be increased to screen out the top-ranked hosts in a distributed manner.

[0074] In block 720, the terminal device 110 presents a first component associated with the first interaction event in the live interface.

[0075] For example, referring to Figure 3B , the first component is the Figure 3B progress bar in. Since the progress bar is more intuitive, the host and the audience can directly understand the current live situation through the progress bar.

[0076] In block 730, the terminal device 110 divides the first component into multiple sub-regions based on the current event phase of the multiple event phases.

[0077] In some embodiments, the multiple sub-regions include a first sub-region and a second sub-region. The first sub-region corresponds to a first event state, and the second sub-region corresponds to a second event state. The first event state indicates that the first live user is allowed to enter the next event phase, and the second event state indicates that the first live user is not allowed to enter the next event phase. For example, referring to Figure 3B , the progress bar can be divided into a first sub-region 301 and a second sub-region 302. At the end of the time, the hosts in the first sub-region 301 are allowed to enter the next phase, and the hosts in the second sub-region 302 are not allowed to enter the next phase.

[0078] In some embodiments, the first component presents a first element corresponding to the first live user. The first live user corresponds to the live interface, and the display position of the first element in the first component is determined based on the first interaction information of the first live user in the first interaction event.

[0079] In some embodiments, the first element includes an image identifier of the first live user. For example, the first element can be the avatar of the host.

[0080] In some embodiments, the display position of the first element is determined based on the ranking of the first interaction information among the interaction information corresponding to multiple live users, and the first sub-region corresponds to a first ranking range, and the second sub-region corresponds to a second ranking range. For example, referring to Figure 3B , if the maximum remaining number of people in the first event stage is set to 43, and if the current ranking of the host enters the top 43, the host's avatar can be displayed in the first sub-region 301. If the current ranking of the host does not enter the top 43, the host's avatar can be displayed in the second sub-region 302. That is, by displaying the host's avatar in the first component of the live interface, both the host and the audience can understand the current ranking of the host and whether the host is in a dangerous state.

[0081] In some embodiments, the positional relationship between the first element and multiple sub-regions is used to characterize the event state of the first live user in the current event stage, and the division of the multiple sub-regions changes with the switching of the event stage.

[0082] In some embodiments, in response to a first interaction event, the terminal device 110 switches to the next event stage, reduces the first size of the first sub-region, and increases the second size of the second sub-region. For example, if the maximum remaining number of people in the first event stage is set to 43 and the maximum remaining number of people in the second event stage is set to 40, then in the second event stage, the area of the first sub-region is smaller than the area of the first sub-region in the first event stage, and in the second event stage, the area of the second sub-region is larger than the area of the second sub-region in the first event stage. In this way, during the process of multiple event stages, the area of the first sub-region can be gradually reduced, that is, fewer hosts are allowed to enter the next event stage, thereby continuously increasing the competitiveness of the live broadcast.

[0083] In some embodiments, in response to the second interaction information of the second live user among multiple live users satisfying a first condition, the terminal device 110 presents a second element corresponding to the second live user in the second sub-region. For example, referring to Figure 3A , if the maximum remaining number of people in the first event stage is set to 43 and the ranking of the second live user does not enter the top 43, the avatar of the second live user is displayed in the second sub-region. In this way, both the host and the audience can not only understand the current ranking situation but also know which hosts are currently in a dangerous state.

[0084] In some embodiments, timing information associated with the current event stage is presented in the live interface. For example, referring to Figure 3B , "01:52" can be displayed on the interface to prompt the host of the remaining duration of this stage.

[0085] In some embodiments, the terminal device 110 presents an information control associated with a first interaction event in the live broadcast interface, and the information control is configured to present the status information of the first live user in the first interaction event.

[0086] In some embodiments, in response to the triggering of the information display control, the terminal device 110 presents a viewing panel associated with the first interaction event. For example, referring to Figure 3B When the host triggers the information display control 304, it can jump to Figure 6A the interface to view the status information of the current live broadcast.

[0087] In some embodiments, the live broadcast event further includes a third interaction event. After the first interaction event ends, in response to the first historical interaction information of the first live user in the first interaction event satisfying a third condition, a third component associated with the third interaction event is presented in the live broadcast interface. The third interaction event is associated with a third live user among multiple live users, and the second historical interaction information of the third live user in the first interaction event satisfies the third condition.

[0088] For example, the third condition can be set such that the top 8 hosts in the second stage are allowed to enter the third stage. The third interaction event is the third stage. Referring to Figure 4A is the live broadcast interface corresponding to the third stage. In the third stage, according to the gifts or likes given by the audience to the hosts, the hosts compete one-on-one to determine the winner. Through the one-on-one confrontation method, the competition needs when the number of hosts is small can be met, and the confrontation of the live broadcast can be gradually enhanced.

[0089] In some embodiments, the terminal device 110 presents the third interaction information of the first live user in the third live interaction event and the fourth interaction information of the third live user in the third live interaction event in the third component.

[0090] For example, referring to Figure 4A is the live broadcast interface for the confrontation between the first live user and the third live user. The third component 401 may include the avatars of the first live user and the third live user. These two avatars can move in the third component 401, and the current confrontation situation of the two hosts can be determined according to the moving positions. In this way, the hosts and the audience can intuitively understand the current confrontation situation.

[0091] By setting multiple interactive events in a live event and adopting different mechanisms for different interactive events, the diversity of live broadcasts is greatly enriched, thus meeting various live broadcast requirements. And by setting multiple interactive events, it is also possible to meet the needs of different numbers of live broadcast participants. There are not only competition mechanisms set for a relatively large number of hosts, but also competition mechanisms set for a relatively small number of hosts, so there is no need for excessive restrictions on the number of people. Moreover, the live broadcast interface is very simple, greatly reducing the understanding cost for both hosts and audiences, so as to attract more hosts and audiences to participate.
