     Embodiment One 
       FIG.  1    is a flowchart of a target content search method according to embodiment one of the present disclosure. The embodiment of the present disclosure is applicable to the case where target search content corresponding to content to be processed is determined according to a search identifier in search content to be processed and content consistent with the target search content is selected from a text. The method may be performed by a target content search apparatus, and the apparatus may be implemented in the form of software and/or hardware. 
     As shown in  FIG.  1   , the method in this embodiment includes the steps described below. 
     In S 110 , a target search identifier in search content to be processed is determined and a target search strategy corresponding to the target search identifier is determined. 
     The search content to be processed is content acquired from a target page. A search content editing control is included on the target page. In the search content editing control, the user may edit corresponding content, and the edited content is used as the search content to be processed. Optionally, text information generated according to voice information of different language types or the same language type may further be included on the target page. A variety of search identifiers, optionally, “,” and the like are included in the search content to be processed. The search identifier may be preset. In the case where it is detected that the preset search identifier is included in the search content to be processed, it is determined that the search content to be processed includes the search identifier, and the search identifier included in the search content to be processed may be used as the target search identifier. 
     When the search content to be processed is acquired, whether the search content to be processed includes the search identifier may be determined according to the preset search identifier. If the search content to be processed includes the search identifier, the search identifier in the search content to be processed may be used as the target search identifier. After the target search identifier is determined, the search strategy corresponding to the target search identifier may be determined, so as to determine target search content corresponding to the search content to be processed according to the search strategy. 
     In some optional implementations of this embodiment, the step of acquiring the search content to be processed that is edited in the search content editing control includes if it is detected that a control for starting a search is triggered, acquiring target search content edited in the search content editing control. Exemplarily, the target page may include the search content editing control and the control for starting a search. Optionally, the control for starting a search may be a “search confirmation” control. A user may edit corresponding content in the search content editing control, and after the content editing is completed, the user may trigger the control for starting a search, that is, click on the “search confirmation” control, and a server may acquire the search content to be processed in the search content editing control. 
     Alternatively, in other optional implementations, if the search content editing control is triggered, the search content to be processed that is edited in the search content editing control is acquired. 
     Exemplarily, the target page includes the search content editing control. In the case where it is detected that the user triggers the search content editing control, acquisition of the search content edited in the search content editing control is started, and within a preset time period, optionally, within 30 s, if it is not detected that the user edits new search content, the acquired search content is used as the search content to be processed. 
     In S 120 , target search content corresponding to the search content to be processed is generated according to the target search identifier, the target search strategy, and the search content to be processed. 
     The target search strategy corresponds to the target search identifier, and the target search content corresponding to the search content to be processed may be determined according to the corresponding target search strategy. That is, the target search content is search content obtained after processing the search content to be processed according to the target search strategy. In this embodiment, one, two, or more pieces of the target search content may exist, and the number of pieces of the target search content is related to the target search strategy. 
     If the search content to be processed includes multiple target search identifiers, the target search strategy corresponding to each target search identifier may be determined, and then the search content to be processed is processed according to the target search strategy, so as to obtain the target search content corresponding to the search content to be processed. 
     In S 130 , target content corresponding to the target search content is searched out from text information. 
     The text information may be any text. Optionally, the text information is a document pre-acquired through an acquisition manner. The text information may be a text determined according to audio information of a multimedia data stream. The multimedia data stream may be generated according to a real-time interactive scenario (for example, a multimedia conference, a live broadcast, and a video chat) or obtained according to recordings. 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, a World Wide Web (Web) program, or the like. The audio information of the multimedia data stream may be collected, converted into the corresponding text, and displayed on the target page. The text displayed on the target page may be used as the text information. The target content is the same content as the target search content. 
     According to the target search content, the same content as the target search content may be selected from the text information and used as the target content. In the technical solution of this embodiment, since the target search content is associated content associated with the search content to be processed, the content associated with the search content to be processed may be selected from the text information according to the target search content, thereby improving the comprehensiveness of the determined target content. 
     In the technical solution of the embodiment of the present disclosure, the target search identifier in the search content to be processed is acquired, the target search strategy corresponding to the target search identifier is determined, the search content to be processed is optimized according to the target search strategy, that is, a search condition is optimized, and the corresponding target content is selected from the text information according to the optimized search condition, thereby improving the comprehensiveness of the determined target content. 
     According to the preceding technical solution, after the target content the same as the target search content is selected from the text information, in order to be convenient for the user to determine a position of the target content in the text, the target content may be displayed distinguishably in the text information. 
     The target content itself is one or more elements in the text information. When displayed, the target content may be displayed distinguishably from other elements, so as to highlight the selected target content, so that the user can find the target content more intuitively and conveniently. The distinguishable display may be in a color, a font, a background pattern, and other display formats. 
     In some optional implementations of this embodiment, before the target content is selected from the text information, the corresponding text information needs to be generated. Optionally, the step of generating the text information according to the multimedia data stream may be: collecting voice information according to the multimedia data stream; and according to the voice information, an original language type corresponding to the voice information, and a target translation language type, generating the text information that is displayed on the target page and corresponds to the target translation language type. 
     In some application scenarios, multiple users may participate in real-time interaction or participate in speaking in a screen-recorded video, a language type used by each speaking user to speak may be the same or different, and when language types used by other speaking users differ greatly from the language type used by the present user, the case where the present user cannot know speaking information of other speaking users may exist. 
     To solve this problem, on the basis of converting the collected voice information of the speaking user into the text information generated according to the original language type, the text information generated according to the original language type may be converted into the text information corresponding to a language type desired by the user (that is, the target translation language type). 
     The original language type may be understood as the language used by each user participating in voice interaction in the multimedia data stream. Correspondingly, the target translation language type may be understood as the language type desired by the user for displaying the text information. Correspondingly, the text information corresponding to the target translation language type may be translation data that is presented in the target translation language type and corresponds to the voice information. To be convenient for the user to intuitively determine a speaking user and speaking time corresponding to each piece of the translation data from the text information, the text information may display an identity of the speaking user and a speaking timestamp of each piece of the translation data. 
     Voice data, that is, the voice information, of multiple users participating in an interaction may be collected from the multimedia data stream corresponding to an interaction behavior interface, and the original language type corresponding to the voice information may be recorded. The voice information may be translated from the original language type to the target translation language type, so as to obtain the translation data corresponding to the voice information. The translation data, the identity of the speaking user corresponding to the translation data, and the speaking timestamp are used as the text information displayed on the target page. 
     In some application scenarios of these optional implementations, a language type selection control may be provided on the target page. In this manner, the user may select the translation language type by triggering the language type selection control on the target page, so as to translate the text information of the original language type generated by the voice information of the speaking user into the text information corresponding to the selected translation language type. 
     Alternatively, in other application scenarios of these optional implementations, the target translation language type may be determined through at least one of the following manners: acquiring a language type preset on a target client as the target translation language type; or acquiring a login address of the target client and determining the target translation language type corresponding to a geographic location where the target client is located according to the login address. 
     That is, at least two methods for determining the target translation language type are described below. The first method may be: using a default language type in a device to which the speaking user belongs as the target translation language type; or presetting, by the user, a language type to be converted to use the language type preset by the user as the target translation language type. Exemplarily, before the voice information is converted into the text information, the user may preset the target translation language type. Optionally, when the user triggers the language type selection control, a language type selection list may be popped up on the target page for the user to select from. The user may select any language type. For example, the user triggers a Chinese language type in the language type selection list and clicks on a confirmation button, and a server or a client may determine that the target translation language type is the Chinese language type. That is, the voice information in the multimedia data stream may be converted into Chinese text information which is then displayed on the target page. 
     The second method may be: acquiring the login address of the client, that is, an Internet Protocol (IP) address of the client, determining a region to which the client belongs according to the login address, determining a language type used in the region, and using the used language type as the target translation language type. 
     In this embodiment, the voice information in the multimedia data stream is converted into the text information of the target translation language type so that the text information is more in line with reading habits of the user, and the user can quickly understand the content corresponding to the multimedia data stream, thereby improving the interaction efficiency. 
     On the basis of the above, after the text information is obtained, the method further includes establishing a timestamp synchronization association relationship between the text information and the multimedia data stream and displaying the text information and the multimedia data stream on the target page so that in the case where it is detected that the target content is triggered, a video playing moment in the multimedia data stream corresponding to the target content is jumped to. 
     The timestamp synchronization association relationship may be understood that the multimedia data stream and the text information are synchronized and associated based on time. In the case where one piece of content in the text information is triggered, a current timestamp corresponding to the piece of content may be determined, and the multimedia data stream corresponding to the current timestamp is jumped to according to the pre-established timestamp synchronization association relationship. For example, a playing position in the multimedia data stream corresponding to the current timestamp is jumped to. Secondly, since the timestamp synchronization association relationship between the multimedia data stream and the text information is established, when a progress bar of the screen-recorded video is dragged to a position, the current timestamp corresponding to this position may be acquired, and according to the pre-established timestamp synchronization association relationship, the content corresponding to the voice content at the playing position in the text information may be determined. To be convenient for the user to determine a position of the text content corresponding to the audio in the text information, the text content may be displayed distinguishably on the target page according to the timestamp synchronization association relationship. Optionally, the text content is highlighted on the target page. In the case where it is detected the text content in the text information is triggered, the current timestamp corresponding to the text content may be acquired, and a corresponding audio and video frame is acquired and displayed according to the timestamp synchronization association relationship. Optionally, if it is detected that the target content is triggered, the current timestamp of the target content is determined; and the video frame in the multimedia data stream corresponding to the current timestamp is jumped to according to the pre-established timestamp synchronization association relationship and the current timestamp. 
     In the case where it is detected that the user triggers the target content, the current timestamp corresponding to a sentence to which the target content belongs may be acquired. According to the pre-established timestamp synchronization association relationship, the playing position in the multimedia data stream corresponding to the current timestamp is jumped to so that it is convenient for the user to know the mood and state of the speaking user when publishing the voice information including the target content, thereby improving the interaction efficiency. 
     In the preceding technical solution, the method further includes displaying an identifier of the target content on a timeline corresponding to the multimedia data stream. 
     After the target content is determined, a timestamp of a sentence to which each piece of the target content belongs may be determined and used as the current timestamp corresponding to the target content. According to the timeline corresponding to the multimedia data stream, each current timestamp corresponding to the target content is displayed on the timeline so that the user can quickly determine the relative position of each piece of the target content in the multimedia data stream. 
     In the technical solution of this embodiment, the timestamp synchronization association relationship between the multimedia data stream and the text information is established so that synchronization and association between the text information and the multimedia data stream is achieved, and it is convenient for the user to quickly find the position of the corresponding text information in the multimedia data stream and learn the voice information of the speaking user in conjunction with the context, thereby improving the information interaction efficiency. 
     Embodiment Two 
       FIG.  2    is a flowchart of a target content search method according to embodiment two of the present disclosure. according to the preceding embodiment, in the case where the target search identifier in the search content to be processed is acquired, search strategies to be combined corresponding to different target search identifiers may be determined, the target search strategy is determined according to the search strategies to be combined, and the target search content corresponding to the search content to be processed is determined according to the target search strategy. Technical terms identical to or corresponding to the preceding embodiments are not repeated here. 
     As shown in  FIG.  2   , the method includes the steps described below. 
     In S 210 , at least one target search identifier in the search content to be processed is acquired. 
     The search content to be processed may include one or more target search identifiers. The target search identifiers may be preset special symbols. The special symbols may be “,”, “-”, and the like. 
     A search identifier library can be preset and includes multiple search identifiers. Correspondingly, to quickly call a search strategy corresponding to each search identifier, a correspondence between the search identifier and the search strategy may be established so that in the case where it is detected that the search identifier exists, the search strategy corresponding to the search identifier is called according to the correspondence. In this embodiment, the step of acquiring multiple target search identifiers in the search content to be processed may be: according to the preset search identifier library, determining the search identifiers included in the search content to be processed; or acquiring multiple symbols in the search content to be processed, determining a target symbol from the multiple symbols according to the preset search identifier library, and using the target symbol as the target search identifier. 
     The search content to be processed may include one, two, or more target search identifiers which may be the same or different. If the target search identifiers are the same, the corresponding search strategies are the same. 
     In S 220 , search strategies to be combined which are in one-to-one correspondence with the target search identifiers are determined. 
     After multiple target search identifiers are acquired, the search strategy corresponding to each target search identifier may be determined according to a correspondence table, and the determined search strategy is used as the search strategy to be combined. That is, the search strategy corresponding to each target search identifier may be used as the search strategy to be combined. 
     If multiple target search identifiers included in the search content to be processed are the same, the search strategies to be combined corresponding to the target search identifiers are the same; and if different target search identifiers exist among the multiple target search identifiers, the corresponding search strategies to be combined may be the same or different. 
     In this embodiment, the step of determining the search strategy to be combined corresponding to each target search identifier may be: pre-establishing a correspondence between the search identifier and the search strategy. After the target search identifier is acquired, the search strategy to be combined corresponding to the target search identifier may be determined according to the correspondence between the search identifier and the search strategy. If one target search identifier exists, one strategy to be combined may exist; and if multiple target search identifiers exist, multiple search strategies to be combined may exist. 
     In S 230 , the target search strategy corresponding to the search content to be processed is generated according to each of the search strategies to be combined. 
     The target search strategy is made according to each search strategy to be combined. In the case where one search strategy to be combined exists, one target search strategy exists; and in the case multiple search strategies to be combined exist, the target search strategy includes multiple search strategies to be combined. 
     In S 240 , content to be converted in the search content to be processed is determined according to the at least one target search identifier, the content to be converted is processed according to the target search strategy, and content to be replaced corresponding to the content to be converted is determined. 
     The content to be converted is determined according to the target search identifier. The content to be replaced is obtained after processing the content to be converted according to the target search strategy. 
     If multiple target search identifiers exist, each target search identifier may be processed so as to determine the search strategy corresponding to each target search identifier and the content to be converted, and the content to be replaced corresponding to the content to be converted is determined according to the content to be converted and the search strategy corresponding to the content to be converted. 
     In this embodiment, the target search strategy includes at least one of the following: a search strategy of performing a combined search for part of character strings in the search content to be processed; a search strategy of determining associated content of part of character strings in the search content to be processed and performing a search according to the associated content; or a search strategy of performing a split search for part of character strings in the search content to be processed. 
     That is, the search strategy to be combined may be any of the preceding search strategies. The target search strategy is one or more of the preceding search strategies to be combined. Part of the character strings are determined according to the target search identifier in the search content to be processed. 
     A combined search strategy may be understood as a search strategy of performing a search with the character strings and the target search identifier as a whole after the character strings are determined according to the target search identifier. The search strategy of performing a search according to the associated content may be a strategy of determining a character string according to the target search identifier, determining content associated with the character string, and performing a search according to the determined associated content. The search strategy of split search refers to that after the character string is determined according to the target search identifier, each character string is used as the content to be replaced. 
     In this embodiment, the corresponding target search strategy and the content to be converted may be determined according to the target search identifier, and the content to be replaced may be generated according to the content to be converted so that the target search content may be generated according to the content to be replaced and the search content to be processed. 
     The different search identifiers may be divided into at least three types, that is, a first target search identifier, a second target search identifier, and a third target search identifier, and the search strategies corresponding to the different search identifiers may be divided into at least three types. If the search content to be processed includes multiple types of search identifiers, the search strategy corresponding to each type of search identifier may be determined separately, the content to be replaced is determined, and the target search content is generated according to the content to be replaced. 
     In this embodiment, for determining the content to be converted and the content to be replaced in the search content to be processed according to the target search identifier, reference may be made to at least one of the manners described below. For specific embodiments corresponding to the preceding three types of search strategies, reference may be made to the description described below. 
     The first manner may be: if the target search identifier includes the first target search identifier, determining a character string adjacent to the first target search identifier according to the first target search identifier and generating the content to be converted according to the character string; and generating the content to be replaced according to the content to be converted and the first target search identifier. 
     The first target search identifier may be an abbreviated identifier. Optionally, if “you&#39;ll” is included in the search content to be processed, the target identifier in this case may be “′”, and “′” may be used as the first target search identifier. After the target identifier is determined, the character string adjacent to the target identifier may be determined, and the adjacent character string may be used as the content to be converted. For example, if the target identifier is “′” and the character string adjacent to the target identifier is “you ll”, “you ll” may be used as the content to be converted. The content to be replaced is generated according to the content to be converted and the first target search identifier. Since the target search strategy corresponding to the first target search identifier is the search strategy of performing a combined search for part of character strings in the search content to be processed, the content to be converted and the first target identifier may be combined together as the content to be replaced, and the obtained content to be replaced may be “you&#39;ll”. 
     According to the preceding manner, the content to be converted in the search content to be processed can be determined and the content to be replaced corresponding to the content to be converted can be obtained. 
     The second manner may be: if the target search identifier includes the second target search identifier, acquiring a target character string before and adjacent to the second target search identifier in the search content to be processed and using the target character string as the content to be converted; and determining at least one associated word corresponding to the target character string and determining the content to be replaced according to the at least one associated word. 
     The target search strategy corresponding to the second target search identifier may be a search strategy of determining associated content of part of character strings in the search content to be processed and performing a search according to the associated content. The second target search identifier is preset. If it is detected that the second target search identifier exists, the character string before and adjacent to the second target search identifier may be acquired as the target character string. The target character string may be used as the content to be converted. Since the search strategy corresponding to the second target search identifier is a search strategy of acquiring the associated content of part of character strings, the associated content may be obtained after performing at least one form transformation on the target character string. Optionally, a tense change, singular and plural changes, and the like are performed on the target character string. A word associated with the target character string may be used as the content to be replaced. 
     In the case where it is detected that the target search content includes the second target search identifier, the character string before and adjacent to the second target search identifier in the search content to be processed may be acquired as the target character string, and the target character string is used as the content to be converted. Whether the associated content of the target character string exists may be detected. Optionally, the associated content may be words corresponding to the target character string in different tenses, words in a singular form or a plural form, and the like. If the associated content of the target character string exists, the associated content of the content to be converted is determined, and the determined associated content is used as the content to be replaced. 
     In this embodiment, the associated word, that is, the associated content, includes at least one of a derivative of the target character string, a character string in multiple tenses corresponding to the target character string, a singular form of the target character string, or a plural form of the target character string. 
     The derivative may be a word corresponding to the target character string determined by using the target character string as a root word. The tenses include the present tense, the future tense, and the past tense, and the words corresponding to the target character string in different tenses may be determined. Whether the target character string has a singular form and a plural form may be determined. If the target character string has a singular form and a plural form, the singular form and the plural form of the target character string are associated words. 
     Whether the associated word of the target character string exists may be determined. If the associated word of the target character string exists, the corresponding associated word may be acquired according to the preceding principle, and the associated word is used as the content to be replaced. 
     The third manner may be: if the target search identifier includes the third target search identifier, determining a character string adjacent to the third target search identifier according to the third target search identifier and generating the content to be converted according to the character string; and using each character string in the content to be converted as the content to be replaced. 
     The target search strategy corresponding to the third target search identifier may be the search strategy of performing a split search for part of character strings in the search content to be processed. Part of character strings are determined according to the third target search identifier. The third target search identifier is an identifier for performing a split search for part of character strings. Optionally, the third identifier may be “,”, “-”, and the like. If it is detected that the search content to be processed includes the third target search identifier, the character string adjacent to the third target search identifier is determined. Since the search strategy corresponding to the third target search identifier is the character string split search strategy, the character strings determined in this case may be used as the content to be converted separately. 
     Exemplarily, if “A-B” is included in the search content to be processed and the acquired search identifier included in the search content to be processed is “-”, the target search identifier is determined to be “-”. The target search strategy corresponding to “-” is a strategy of performing a split search for part of character strings, and the character strings adjacent to the target search identifier may be acquired. Optionally, the acquired adjacent character strings are “A” and “B”, that is, the character strings “A” and “B” are the content to be converted. “A” and “B” in the content to be converted may be used as the content to be replaced, respectively. 
     In S 250 , the target search content is generated according to the content to be replaced and the search content to be processed. 
     If the search content to be processed includes one target search identifier, at least one piece of the content to be replaced corresponding to the target search identifier may be determined, and both the content to be replaced and the search content to be processed may be used as one search condition in the target search content. If the search content to be processed includes at least two target search identifiers, the content to be converted corresponding to each target search identifier and at least one piece of the content to be replaced corresponding to each piece of the content to be converted may be determined according to corresponding search strategies, respectively. Each piece of the content to be converted is separately replaced with the content to be replaced, so as to obtain the target search content. 
     Optionally, the content to be converted in the search content to be processed is replaced with the content to be replaced, so as to obtain at least one piece of target sub-search content; and the target search content is generated according to the at least one piece of target sub-search content. 
     More than one piece of the content to be replaced corresponding to the search content to be processed exists, and a corresponding position in the search content to be processed may be replaced with the content to be replaced. Optionally, the corresponding content to be converted is replaced with the content to be replaced, and the search content to be processed after the replacement is used as one piece of target sub-search content in the target search content. That is, the target search content may include multiple pieces of target sub-search content, and the target sub-search content is obtained after the content to be converted in the search content to be processed is replaced with the content to be replaced. The number of pieces of target sub-search content corresponds to the number of pieces of content to be replaced. 
     The content to be replaced corresponding to each piece of the content to be converted may be acquired, and the content to be converted may be replaced with the corresponding content to be replaced, so as to obtain at least one piece of target sub-search content in the target search content. A set of at least one piece of target sub-search content is the target search content. 
     In S 260 , according to the target search content, content identical to the target search content is searched out from the text information so as to obtain the target content. 
     After the target search content is determined, the content identical to the target search content may be acquired from the text information and used as the target content. 
     In the technical solution of the embodiment of the present disclosure, the target search identifier in the search content to be processed is acquired, the target search strategy corresponding to the target search identifier is determined, and the search content to be processed is improved and enriched according to the target search strategy so that the target search content is obtained, and when the corresponding target content is searched from the text information according to the target search content, the comprehensiveness and richness of the target content are improved. 
     According to the preceding technical solution, the method further includes determining a timestamp of each piece of the target content on the timeline corresponding to the multimedia data stream and marking a position corresponding to the timestamp on the timeline. 
     The timeline corresponds to the multimedia data stream. Optionally, the total duration corresponding to the multimedia data stream is 50 min, and the timeline corresponding to the multimedia data stream is also 50 min. 
     After the target content is determined, the timestamp corresponding to the target content may be determined according to a sentence to which the target content belongs. After the timestamp corresponding to the target content is determined, a position of the timestamp corresponding to the target content on the timeline may be determined and marked. For example, the position is marked with a dot below the timeline or with a triangle, as shown in  FIG.  3   . 
     According to the preceding technical solution, the step of marking the position of the timestamp corresponding to the target content on the timeline includes determining a position of a control among multiple controls in one-to-one correspondence with all timestamps on the timeline and marking the position; where the control corresponds to the timestamp which corresponds to the target content and is used for adjusting an audio and video frame of the multimedia data stream. Referring to  FIG.  3   , the position of the control is where the dot mark is located. 
     Exemplarily, referring to  FIG.  3   , the search content edited by the user in the search content editing control is “algorithm”, the target content the same as the “algorithm” may be searched out from the text information and displayed distinguishably, for example, highlighted, the timestamp of the sentence to which the target content belongs is determined, and marking is performed on the timeline corresponding to the multimedia data stream according to the timestamp. For example, marking is performed with the dot. The color, size, and the like of the mark may be set by the user according to actual requirements and not limited herein. 
     The number of pieces of the target content may be displayed in the search content editing control. For example, the total number displayed in the search content editing control is 12, as shown in  FIG.  3   . 
     In this embodiment, marking the audio and video frame corresponding to the target content on the timeline is advantageous in that the user can clearly determine the position of the target content in the multimedia data stream according to the mark on the timeline, thereby improving the convenience of finding the corresponding target content. 
     More than one piece of the target content may exist. Correspondingly, more than one mark exists on the timeline. Referring to  FIG.  3   , the number of pieces of the target content is 12, and the number of marks on the timeline is also 12. To be convenient for the user to determine the ranking of the currently triggered target content among all pieces of the target content, the search content editing control further displays a sequence to which the currently triggered target content corresponds. 
     According to the preceding technical solution, the method further includes in the case where it is detected that one piece of the target content is triggered, determining a target timestamp corresponding to the one piece of the target content; and displaying a mark corresponding to the target timestamp distinguishably. 
     The user may trigger any one of pieces of the target content. In the case where it is detected that the user triggers the target content, the timestamp (the target timestamp) corresponding to the target content triggered by the user may be determined, a target mark corresponding to the target timestamp on the timeline may be determined, and the target mark is displayed distinguishably from other marks on the timeline, so as to highlight the target mark. For example, the target mark and other marks are displayed distinguishably in different colors. 
     Exemplarily, referring to  FIG.  4   , in the case where the user triggers the target content corresponding to mark  1 , the timestamp (which is also referred as to the target timestamp) corresponding to the target content corresponding to the mark  1  may be determined, and according to the target timestamp, a position of mark  2  corresponding to the target timestamp on the timeline may be determined, so as to highlight the position of the mark  2 . 
     In this embodiment, in the case where the target content is triggered, distinguishably displaying the mark corresponding to the target content on the timeline is advantageous in that the user can learn the position of the triggered target content in the multimedia data stream, thereby improving the accuracy of the audio and video frame corresponding to the target content determined by the user.
