       FIG. 1  is a flowchart of an interactive information processing method according to an embodiment of the present disclosure. The embodiment of the present disclosure is suitable for establishing a position linkage between a multimedia data stream and a display text, so as to achieve the linkage between the display text and the multimedia data stream when the display text or the multimedia data stream is triggered to be displayed. The method may be executed by an interactive information processing apparatus. The apparatus may be implemented by software and/or hardware, for example, by an electronic device. The electronic device may be a mobile terminal, a personal computer (PC) side, a server terminal, or the like. The method provided in this embodiment may be executed by a client, by a server terminal, or by both. 
     As shown in  FIG. 1 , the method in this embodiment includes the steps described below. 
     In S 110 , a position correspondence is established between a display text generated based on a multimedia data stream and the multimedia data stream. 
     The multimedia data stream may be audio-video stream data corresponding to a real-time interactive interface, or video stream data in a recording screen video after a real-time interactive interface is recorded. The real-time interactive interface is any interactive interface in a real-time interactive application scenario. The real-time interactive scenario may be implemented by means of the Internet and a computer, for example, an interactive application program implemented through a native program or a web program, etc. An audio frame of the multimedia data stream may be processed, for example, audio information is extracted from the audio frame to obtain text information corresponding to the multimedia data stream, and the text information is displayed on a target page. Correspondingly, the text information displayed on the target page is the display text. In order to achieve the effect of a synchronous linkage between the display text and the multimedia data stream, the position correspondence between the display text and the multimedia data stream may be established. The position correspondence may be determined based on the timestamp. For example, in some application scenarios, the display text may be obtained by performing the speech recognition on speech in the multimedia data stream. In these application scenarios, a position of the speech, which corresponds to a certain paragraph of characters in the display text, in the multimedia data stream may be used as a timestamp of the paragraph of characters, and a position correspondence between the paragraph of characters and the corresponding speech may be established. 
     In S 120 , the display text and the multimedia data stream corresponding to the display text are presented based on the position correspondence. 
     For example, the display text and the multimedia data stream between which the position correspondence has been established may be displayed on the target page. Thus, when a triggering operation (e.g. a click, etc.) on a certain part of the display text is detected, a video frame corresponding to the display text may be displayed according to the position correspondence. 
     In the technical scheme of the embodiments of the present disclosure, the position correspondence is established between the multimedia data stream and the display text, and when triggering the target content of the display text is detected, the multimedia data stream may be jumped to the video frame corresponding to the target content, so that a user can understand speech information of a speaking user by combining the video frame and the target content, thus improving the technical effect of the interaction efficiency. 
       FIG. 2  is a flowchart of an interactive information processing method according to another embodiment of the present disclosure. On the basis of the preceding embodiment, the corresponding display text is generated according to the multimedia data stream to establish a position correspondence between the display text and the multimedia data stream. Technical terms identical to or corresponding to the preceding embodiments are not repeated here. 
     As shown in  FIG. 2 , the method includes the steps below. 
     In S 210 , an audio-video frame of the multimedia data stream is acquired, and a user identity of a speaking user corresponding to the audio-video frame is determined. 
     The multimedia data stream refers to a data stream acquired from a real-time interactive interface. An interactive scenario achieved by a plurality of users based on the Internet or a computer is used as the real-time interactive scenario, for example, a multi-participant video conference, a live broadcast and the like. After the real-time interaction, to conveniently review the conference content or determine the core idea corresponding to the speech made by one or several speaking users, the real-time interactive scenario may be recorded during the real-time interaction process, for example, the video conference content may be recorded. The recorded real-time interactive scenario is used as a recording screen video. Correspondingly, the multimedia data stream is acquired based on the recording screen video. The recording screen video includes not only audio information of each speaker, but also video information, that is, the multimedia data stream corresponds to audio frames and video frames. The user identity is used for representing the identity of each user. 
     For example, a user corresponding to a terminal to which the audio information belongs may be determined based on the audio frames and the video frames of the multimedia data stream, and then the user identity of the speaking user corresponding to the audio frames and/or the video frames may be determined. 
     In S 220 , a display text corresponding to the multimedia data stream is generated based on the user identity and the audio-video frame. 
     The literal expression corresponding to an audio frame may be determined based on the audio information, i.e., the audio frame, of the multimedia data stream. A video frame of the multimedia data stream may be a document shared by an interactive user, a shared screen, etc. Information such as literal information and/or links on a display interface may be determined based on the video frame. The display text corresponding to the recording screen video may be determined based on the audio frame and the video frame. The correspondence may be a correspondence between the timestamp of the multimedia data stream and the timestamp in the display text. The target page may be a page displayed on the client. The page may include the multimedia data stream and the display text. 
     For example, the audio frames and the video frames of the multimedia data stream may be processed to obtain the literal expression corresponding to each audio frame and/or each video frame. The display text corresponding to the multimedia data stream is generated based on the user identity and the timestamp corresponding to each audio-video frame. To achieve a linkage between the display text and the multimedia data stream, the position correspondence between the multimedia data stream and the display text may be established. For example, the multimedia data stream is acquired based on the recording screen video. When it is detected that a progress bar of the recording screen video on the target page is triggered, a playback moment corresponding to the current video frame may be determined, and a text content corresponding to the playback moment may be displayed differentially in the displayed text. 
     In S 230 , the audio-video frame of the multimedia data stream is acquired, and the user identity of the speaking user corresponding to the audio-video frame is determined. 
     In S 240 , the display text and the multimedia data stream corresponding to the display text are presented based on the position correspondence. 
     The technical scheme of the embodiments of the present disclosure, by processing the audio-video frame of the multimedia data stream, the text information corresponding to the multimedia data stream may be generated and displayed on the target page. Through the position correspondence between the multimedia data stream and the text information displayed on the target page, a timestamp synchronization correspondence between the multimedia data stream and the display text is achieved, and the synchronization between the text reading and video watching of users is improved, thus improving the user experience. 
     In this embodiment, determining the user identity of the speaking user corresponding to the audio frame based on the audio frame of the multimedia data stream includes determining the user identity of the speaking user by performing the voiceprint recognition on the audio frame; and/or, determining a client identity of a client to which the audio frame belongs, and determining the user identity of the speaking user based on the client identity. 
     Generally, the voiceprint recognition is a kind of biometric recognition, which is used for identifying the identity according to acoustic characteristics of the speaking user. Since the language of each speaking user has a unique voiceprint, speaking users with different identities may be identified accordingly. Of course, the identity of the client to which each speaking user belongs may also be collected, and the user identity of each speaking user is determined based on the identity of the client. 
     For example, the acoustic characteristic processing may be performed on the audio frames in the multimedia data stream, and the user identity of each speaking user is determined according to a processing result. Generally, a client has its corresponding client account or client identity (ID) for distinguishing different clients. Therefore, the client to which each speaking user belongs is acquired, and the user identity corresponding to each speaking user may be determined based on the identity of the client. However, when multiple users speak on a certain client at the same time, the multiple users cannot be distinguished through the client ID. Therefore, the voiceprint recognition may be further performed on voice data of each user, and the voice of each person has a unique voiceprint, so that different users can be distinguished according to the voiceprint. Then the multiple uses may be marked as a client ID-user A and a client ID-user B, respectively, so as to distinguish identity information of different speaking users on the same client, that is, the user identity. 
     In this embodiment, the identity information of different speaking users is determined. After the audio information of each speaking user is converted into characters, the speaking user corresponding to the literal content may be determined, thereby facilitating other users to determine the core idea expressed by the speaking user corresponding to the speaking content, thereby achieving the technical effect of improving the interaction efficiency. 
     On the basis of the preceding technical schemes, generating the display text based on the user identity and the audio-video frame includes obtaining a literal expression corresponding to the audio frame by performing the speech-to-text processing on the audio frame, and generating a first display text in the display text based on the literal expression and the user identity; and obtaining characters in the video frame by performing an image-text recognition on the video frame, and generating a second display text in the display text based on the characters and the user identity. 
     For example, the audio frame in the recording screen video may be converted into the corresponding literal expression based on a speech-to-text module. The first display text in the display text may be generated based on the identity of the speaking user corresponding to the literal presentation and the audio. That is, the display text includes at least one display text, and each of the at least one display text may display the corresponding content. For example, the content displayed in the first display text may be characters generated based on the audio frame. After characters in a video image are determined based on the video frame, the second display text in the display text may be determined based on the characters in the video frame, that is, the second display text displays the content corresponding to the video image. Exemplarily, if the speaking user A shares a screen, the literal content in the screen may be recognized, and the literal content is displayed in the second display text. 
     It should be noted that the processed content for the audio frame and the video frame may be uniformly displayed in the same text, so the first display text and the second display text are the same. 
     In this embodiment, the content corresponding to the audio-video frame is displayed in the display text, and the audio frame of each speaking user in the recording screen video may be intuitively displayed as corresponding characters, thus improving the convenience of determining the speaking content of the speaking user. 
     On the basis of the preceding technical schemes, obtaining the literal expression corresponding to the audio frame by performing the speech-to-text processing on the audio frame, and generating the first display text in the display text based on the literal expression and the user identity include determining the literal expression corresponding to the audio frame, a timestamp currently corresponding to the audio frame and a user identity of a speaking user to which the audio frame belongs, and generating one piece of display content in the display text based on the user identity, the timestamp and the literal expression. 
     It should be noted that the display text includes at least one piece of display content. When the speaking user speaks, speech information of the speaking user may be converted into a corresponding literal expression. One piece of display content in the first display text may be generated based on a timestamp of the speech information of the speaking user and literal information corresponding to the speech information. 
     For example, for continuous audio frames, when the continuous audio frames belong to the same speaking user, the literal expression corresponding to the continuous audio frames, a user identity corresponding to the continuous audio frames and timestamps corresponding to the continuous audio frames are determined, and one piece of display content in the first display text may be generated. 
     It should be noted that the first display text may include multiple pieces of display content, each piece of the display content includes a speaking user identity, a speaking timestamp and specific speaking content, and the user identity corresponding to each piece of display content may be the same or different, but the timestamp corresponding to each piece of display content is different. 
     In order to improve the readability of the display content in the display text, one piece of display content may include at least two display paragraphs. For example, obtaining the literal expression corresponding to the audio frame by performing the speech-to-text processing on the audio frame, and generating the first display text in the display text based on the literal expression and the user identity include generating a next paragraph in the display content based on the latter audio frame in the process of performing the speech-to-text processing on the audio frame, when it is detected that an interval duration between adjacent audio frames is greater than or equal to a preset interval duration threshold and a user identity of a latter audio frame of the adjacent audio frames is not changed. 
     That is, when the speech-to-text processing is performed on the audio frame, the interval duration between two adjacent audio frames may be acquired. When the interval duration is less than the preset interval duration threshold, it represents that two audio frames are continuous audio frames. When the interval duration is greater than or equal to the preset interval duration threshold and the user identity of the latter audio frame of the two adjacent audio frames is not changed, it represents that the speaking user is not changed and only a pause exists in the speaking process. Based on the content corresponding to the latter audio frame, it may be determined whether the content corresponding to the latter audio frame is generated into the next paragraph in the display content. That is, after the speech content corresponding to the later audio frame is detected, the speech content may be combined with the speech content corresponding to previous audio frames for performing the semantic analysis, and the speech content may be used as one paragraph or two paragraphs according to an analysis result. This can facilitate other users to understand the speech content of the speaking user, thereby improving the high efficiency of understanding the speech content. 
     In order to quickly determine the speaking user corresponding to the display content in the first display text, not only an identity of a user may be determined, but also a user avatar corresponding to each speaking user may be determined. Based on the user avatar, the speaking user corresponding to the literal content in the display text may be further quickly determined. For example, a user portrait corresponding to the user identity is acquired, and one piece of display content in the display text is generated based on the user portrait, the user identity, the timestamp and the literal expression. 
     It can be understood that each piece of display content may include the user avatar, the speaking timestamp (corresponding to a timestamp of the speaking user speaking in the recording screen video), and characters corresponding to the audio information. 
     Of course, if the multimedia data stream is the corresponding video frame of screen sharing, the content in the shared screen may be acquired, for example, the image-text recognition may be performed on the video frame to obtain the second display text in the display text. For example, if the video frame includes at least one uniform resource locator (URL) address, the first display content in the second display text is generated based on the at least one URL address. If the video frame includes a character, the second display content in the second display text is determined based on the character. 
     That is, after the multimedia data stream is acquired, the audio frame of the media data stream may be processed based on the speech-to-text module to obtain the literal expression corresponding to the audio information. To conveniently acquire information such as the screen content, document and link shared by the speaking user in the multimedia data stream, the image-text recognition may be performed on each video frame in the recording screen video to acquire the character and the link in the video frame. The display content in the second display text in the display text is based on the character, the link, the identity of the speaking user and a timestamp corresponding to the content. 
     In the process of a practical application, there is a case that users filter the target content according to keywords, therefore, in the process of generating the display text based on audio-video information, the method further includes determining a third display text in the display text based on the audio-video frame to determine a content corresponding to a target content from the first display text in response to detecting that the target content in the third display text is triggered, and displaying the content differentially. The third display text includes at least one keyword and/or at least one key sentence. 
     That is, in the process of converting the audio-video frame into the corresponding characters, a keyword and/or a key sentence may be extracted from the converted character content, and the keyword and/or the key sentence may be used as the third display text in the display text. In this embodiment, extracting the keyword and/or the key sentence may be that at least one vocabulary is obtained by performing the tokenization processing on the content in the display text and a word vector corresponding to each of the at least one vocabulary may be determined. According to the word vector corresponding to each of the at least one vocabulary, an average word vector is determined, a similarity value between the word vector of each vocabulary and the average word vector is calculated, and a vocabulary whose similarity value is higher than a preset value is used as the keyword. The key sentence in the text may be extracted in the same manner. A relationship between the first display text and each keyword and/or each key sentence in the third display text is established. When the key word or the key sentence is triggered, a position of the keyword or the key sentence in the first display text may be quickly determined from the first display text. Since the position correspondence is established between the display text and the multimedia data stream, when a sentence to which the keyword belongs in the first display text is triggered, the recording screen video may play the multimedia data stream corresponding to the timestamp, based on a timestamp of the sentence to which the keyword belongs. 
     In the process of the practical application, to achieve a reasonable layout, the quick determination of the display content corresponding to each region in the target page may be the determination of a region proportion of each display text on a display page, based on the display content in each display text. 
     For example, the region proportion of each display text on the display page may be dynamically determined according to the display content amount of each display text. For example, the more the display content of a region is, the larger the region on the target page is. 
     The first display text, the second display text, the third display text in the display text and the multimedia data stream are respectively displayed in preset display regions on the target page. A preset display region of the first display text is larger than a preset display region of the recording screen video, the preset display region of the recording screen video is larger than a preset display region of the second display text, and the display region of the second display text is larger than a display region of the third display text. 
     That is, the first display region is mainly used for displaying text data corresponding to the multimedia data stream, so that there is more content, and more regions may be acquired from the target page to display the first display text. An area of a second display region is smaller than an area of the first display region and is used for displaying the multimedia data stream such as the recording screen video; a display area of the third display region is smaller than the display area of the second display region and is used for displaying the content corresponding to the video frame in the multimedia data stream; and a fourth display region is a region for displaying the third display text and is used for displaying the keyword and/or the key sentence extracted from the multimedia data stream. Since the multimedia data stream generally corresponds to a relatively large number of characters, the large number of characters may be displayed in a relatively large font on the target page in order to be easy for users to read; and the content of key sentences or keywords is less, the display region for the content on the display page may be as small as possible. 
     To clearly understand the content displayed on the target page, as shown in  FIG. 3 , the target page may include a control  1 , a control  2 , a control  3  and a control  4 . The control  1  is a control for displaying the first display text, and the speaking content corresponding to each speaking user may be displayed in a text region of the control  1 . The control  2  is a control for displaying the recording screen video, and the recording screen video may be placed in the control  2 . The control  3  is a control for displaying the second display text, and information such as a shared document and a shared link may be displayed in the control  3 . The control  4  is a control for displaying the third display text, and the keywords or key sentences corresponding to the recording screen video and the first display text may be displayed in the control  4 . 
       FIG. 4  is a flowchart of an interactive information processing method according to another embodiment of the present disclosure. On the basis of the foregoing embodiments, there is a case that a language type used by each speaking user speaking in the multimedia data stream is not matched with a current user. Exemplarily, the language type used by each speaking user in the recording screen video includes English and Chinese. If the language type used by the current user is Japanese, the content in the display text and the recording screen video cannot be read or understood. To reduce this kind of situation, a target language type corresponding to a target user (the current user) may be determined in advance. Terminological explanations identical to or corresponding to the above embodiments will not be repeated here. 
     As shown in  FIG. 4 , the method includes steps described below. 
     In S 410 , a user identity of a speaking user corresponding to the audio-video frame is determined based on the audio-video frame of the multimedia data stream. 
     In S 420 , a target language type is determined, and the audio-video frame is converted into a literal expression corresponding to the target language type. 
     The audio-video frame in the multimedia data stream may be converted into a corresponding language type, and the converted language type is used as the target language type. For example, if it is required to convert an audio frame of the recording screen video frame into the language type of Japanese, the target language type may be Japanese. 
     In this embodiment, determining the target language type may be as follows: acquiring a historical language type used by the current client, and determining the target language type based on the historical language type. 
     For example, the historical language type selected by the current client, such as a language type used by the current client before this time, is acquired. The target language type is determined based on the historical language type. 
     In this embodiment, determining the target language type based on the historical language type includes at least one of a use frequency of each historical language type, a language type used in the case of converting a previous audio frame into characters, a language type set by the current client, or a login address of the current client, that is, determining the target language type based on the login address. 
     For example, the use frequency of each historical language type by the current client is acquired, and a language type with the highest frequency may be used as the target language type. For example, the historical language types used by the current client include Chinese with 5 times, English with 2 times and Japanese with 3 times, and Chinese may be used as the target language type based on the use frequency of each historical language type. Alternatively, the language type used in the case of converting the previous audio frame into the characters may be acquired, and the language type previously used is used as the target language type. Alternatively, it may be determined whether a default language type is set in the current client, if the default language type is set in the current client, the default language type is used as the target language type. Alternatively, the login address of the current client is acquired, a region to which the login address belongs is determined, such as China, then Chinese may be used as the target language type; and if the region to which the login address belongs is the United Kingdom, English may be used as the target language type. 
     It should be noted that if the user does not trigger a language type selection control, an original language type of each speaking user may be acquired. The audio information is directly translated into translation data in the original language type, and the user identity and the translation data are used as the display content in the display text. The original language type of the speaking user here may be, for example, the language type used by the speaking user when speaking. 
     On the basis of the technical schemes, to facilitate a user to adjust the language type corresponding to the user in time, the display interface further includes a language type setting control. For example, referring to  FIG. 3 , in response to detecting that a language type selection control  5  is triggered, a language selection list may be popped up and includes at least one language type, and from which the user may select a language type with a relatively high matching degree as the target language type. After the target language type is selected, the display text on the target page may correspond to the target language type. 
     In S 430 , the display text is generated based on the literal expression and the user identity, the position correspondence between the display text and the multimedia data stream is established, and the display text and the multimedia data stream are displayed on the target page. 
     For example, the display text corresponding to the recording screen video is generated based on the literal expression, the user identity and the character expression corresponding to each audio-video frame. 
     According to the technical schemes of the embodiments of the disclosure, the display text corresponding to the recording screen video can be displayed as the character expression corresponding to the target language type by acquiring a preset target language type, which not only improves the convenience for users to read the display text, but also can locate a corresponding position in the recording screen video based on the display text. Further, in a process of reading the display text, the target language type may also be updated based on the language type selection control on the page, further improving the matching degree with the users and the user experience. 
     On the basis of the technical schemes, the method further includes acquiring a search content edited in a search content editing control, and acquiring a target content corresponding to the search content from the display text, each target content is the same as the search content; and displaying the target content differentially in the display text, and marking an audio-video frame corresponding to the target content in a controlling control corresponding to the multimedia data stream. The controlling control is displayed associated with the playback timeline of the multimedia data stream. A position of the audio-video frame corresponding to the target content is marked in the controlling control based on a timestamp of the target content. 
     The search content editing control may be a control displayed on the target page and configured for editing the search content. The target page may include display texts generated based on speech information of different language types. A server may acquire the search content edited in the search content editing control and use the acquired search content as the target content. For example, the search content edited in the search content editing control is “algorithm”, and the target content acquired by the server is algorithm. Differentially displaying may be displaying the target content in bold to distinguish the target content from other content. Marking in the controlling control may be marking the audio-video frame corresponding to the target content. For example, after the audio-video frame corresponding to the target content is determined, a position of the audio-video frame in the controlling control may be determined, and a dot or a triangle is marked below the position, referring to  FIG. 5 . The audio-video frame corresponding to the target content in the multimedia data stream is determined based on a pre-established association, and the audio-video frame corresponding to the target content is marked on the controlling control. In this manner, the user can clearly know the position of the target content in the display text and the position of the target content in the multimedia data stream. 
     It should be noted that in the search content editing control, the number of target content may be displayed, for example, the total number of target content displayed in the search content editing control is 12, referring to  FIG. 5 . 
     It should also be noted that the number of target content may be more than one, and correspondingly, the number of marks on the timeline may be more than one. Referring to  FIG. 3 , the number of target content is 12, and the number of marks on the timeline is also  12 . Of course, to facilitate the user to determine which piece of content in all target content is currently triggered, the search content editing control also displays the order corresponding to the currently triggered target content. 
     In this embodiment, marking the audio-video frame corresponding to the target content in the controlling control corresponding to the multimedia data stream includes: determining a playback timestamp corresponding to the target content, and marking a video playback moment corresponding to the target content in the controlling control corresponding to the multimedia data stream according to the playback timestamp. 
     For example, the playback timestamp corresponding to the target content may be determined, a corresponding multimedia data stream may be determined according to the playback timestamp, and a position corresponding to the playback timestamp is marked in the controlling control. 
     In this embodiment, the method further includes, in response to detecting a triggering operation triggering the target content, determining a target playback timestamp of the target content; and displaying a marker corresponding to the target playback timestamp differentially. 
     For example, the user may trigger the target content, when the target content is triggered, the target playback timestamp corresponding to the target content is determined, and the marker corresponding to the target playback timestamp is displayed differentially from other markers. Differentially displaying may be color-differential displaying, highlight displaying, etc. 
     Exemplarily, referring to  FIG. 6 , when the user triggers the target content corresponding to a marker 1, a target playback timestamp corresponding to the target content of the marker 1 may be determined. According to the target playback timestamp, it may be determined that a marker corresponding to the target playback timestamp on the timeline is the marker 2, and this marker may be highlighted. 
       FIG. 7  is a flowchart of an interactive information processing method according to another embodiment of the present disclosure. On the basis of the foregoing embodiments, after the content displayed on the client display interface is determined, when a control on the target page is triggered, a corresponding operation may be performed. Technical terms identical to or corresponding to the preceding embodiments are not repeated here. 
     As shown in  FIG. 7 , the method includes steps described below. 
     In S 510 , the user identity of the speaking user corresponding to the audio-video frame is determined based on the audio-video frame of the multimedia data stream. 
     In S 520 , the display text is generated based on the user identity and the audio-video frame. 
     In S 530 , the position correspondence is established between the display text and the multimedia data stream. 
     In S 540 , the display text and the multimedia data stream corresponding to the display text are presented based on the position correspondence. 
     In S 550 , in response to detecting a triggering operation triggering a display content in the display text on a target page, the multimedia data stream is adjusted to jump to a video frame corresponding to a timestamp based on the timestamp corresponding to the display content; and/or, in response to detecting a triggering operation for the multimedia data stream, a playback timestamp of the multimedia data stream corresponding to the triggering operation is acquired, and the display text is jumped to the display content corresponding to the playback timestamp in the display text based on the playback timestamp. 
     It should be noted that since there is a certain position linkage relationship between the multimedia data stream and the display text displayed on the target page, a synchronous display between the multimedia data stream and the display text on the target page can be achieved. 
     Exemplarily, referring to  FIG. 4 , in response to detecting a triggering operation on the display content corresponding to a speaking user Andy in the first display text on the target page, based on the timestamp of 00:00:05 corresponding to the display content, a progress bar of the multimedia data stream may jump to a playback moment corresponding to the timestamp of 00:00:05. That is, when a user triggers a sub-control  6  in the control  1 , the progress bar of the multimedia data stream may jump to the playback time of the timestamp corresponding to the sub-control  6 . Correspondingly, in response to detecting a triggering operation triggering the progress bar on the multimedia data stream, the playback moment of the multimedia data stream may be determined, and based on a current playback moment of the multimedia data stream, the display text may be jumped to the literal expression corresponding to the current playback moment in the display text to achieve a linkage between the characters and the multimedia data stream. 
     On the basis of the preceding schemes, it should be noted that the display content corresponding to the multimedia data stream is displayed differentially in the display text based on the position correspondence. 
     For example, the multimedia data stream may be a recording screen video. In the process of playing the recording screen video, the text content corresponding to a current video frame is displayed differentially in the display text, so that the user can know the specific position of the current video frame in the display text, thus facilitating the user to read. 
     In this embodiment, differentially displaying may be presenting the text content corresponding to the current video frame in a manner different from other content in the text. Presenting the text content corresponding to the current video frame may be, but not limited to, the presentation region and/or the presentation style. The presentation region may be a presentation region in the target page that may attract the attention of the user. The presentation style may be any at least one of highlight displaying, bold displaying of the text content corresponding to the current video frame, and displaying a font color differentially from the font color of other content. 
     To achieve the precise adjustment of the multimedia data stream, the target page may also include a controlling control. Referring to  FIG. 3 , a controlling control  7  may also be configured to adjust a current playback moment of the multimedia data stream. To achieve the precise adjustment, the length of a progress bar corresponding to the controlling control  7  is larger than the length of a progress bar in the multimedia data stream. Since a playback duration corresponding to the multimedia data stream is fixed, the longer the length of the progress bar is, the smaller the corresponding change amount is, that is, the higher the corresponding adjustment precision is. Therefore, the length of the progress bar corresponding to the controlling control  7  is larger than an entry bar corresponding to the multimedia data stream, thus the adjustment precision corresponding to the controlling control  7  is higher than the adjustment precision of an adjustment control for the progress of the multimedia data stream in the multimedia data stream. 
     For example, in response to detecting a triggering operation triggering the controlling control on the target page, a playback timestamp corresponding to the controlling control is acquired, the multimedia data stream is adjusted to jump to a playback position corresponding to the playback timestamp based on the playback timestamp, and the content of a display text of a video frame corresponding to the playback timestamp is displayed differentially in the display text. 
     For example, in response to detecting the triggering operation triggering the controlling control on the target page, the playback moment corresponding to the progress bar in the controlling control may be acquired, that is, a position to which the progress bar in the controlling control moves may be dragged, and the position may correspond to the playback timestamp of the multimedia data stream. Based on the playback timestamp, the multimedia data stream is jumped to the audio-video frame corresponding to the playback timestamp, and the display content corresponding to the video frame in the display text is determined at the same time. 
     It should be noted that in the playback process of the multimedia data stream, to facilitate the user to determine the text content corresponding to the current video frame, that is, the text content corresponding to the current video frame is quickly determined from the display text. For example, in the playback process of the multimedia data stream, based on a playback timestamp corresponding to the current audio-video frame, the display content corresponding to the playback timestamp in the display text is determined, and the display content is displayed differentially, such as highlight displaying. In this way, the display content corresponding to the current video frame may be quickly located from the display text, thus improving the convenience and efficiency of the user reading. 
     For example, in response to detecting a triggering operation triggering an editing control on the target page, a permission editing list is displayed, and a user permission of each interactive user is determined based on the permission editing list. The user permission includes a read permission and an editing permission, the read permission is to read text information and video information, and the editing permission is to edit information in a text. 
     It should be noted that the target page further includes an editing control. If a user triggers a permission editing control, a drop-down menu corresponding to the editing permission may be displayed, and the user may edit the user permission of each speaking user in the drop-down menu. The user permission may include the read permission and the editing permission. The read permission is to only browse or read a video or a display text on the target page, but cannot edit the content on the target page. A user with the editing permission can not only edit the content of the display text on the target page, but also share the content with other users. In this way, corresponding permissions can be set for different users, thus effectively avoiding the outflow of internal resources. 
     Exemplarily, referring to  FIG. 3 , in response to detecting a trigger operation triggering the editing control  8  on the target page, the permission editing list may be popped up, and a permission of each interactive user may be edited based on the permission editing list. 
     It should be noted that in the process of the practical application, if the multimedia data stream and the corresponding display text need to be shared to other users, it may be achieved through a sharing control on the target page. For example, in response to detecting a triggering operation triggering the sharing control on the target page, a target link corresponding to the current target page is generated, and the target link is sent to a user to share with, to cause the user to share with to view the multimedia data stream and the display text based on the target link. 
     The sharing control may share the multimedia data stream and the display text included in the target page to other users. 
     For example, in response to detecting a triggering operation triggering the sharing control on the target page, a link based on the content on the target page may be generated and sent to other users. When the link is received by other users, the target page including the multimedia data stream and the display text may be acquired based on the link. 
     Exemplarily, referring to  FIG. 3 , in response to detecting a triggering operation triggering a sharing control  9  on the target page, a target link corresponding to the target page may be generated, and the target link is sent to other users to cause the other users to view the multimedia data stream and the display text based on the target link. 
     On the basis of the technical schemes, it should be noted that in order to make other users to be clear about each interactive user and the total number of users in the multimedia data stream, a head portrait of each interactive user and an identity of the total number of users may be displayed, for example, at a position corresponding to a control  10 , and the host of the multimedia data stream may also be displayed, for example, at a position corresponding to a control  11 .
