[Technical Field]

[0001] The present application relates to the field of subtitling technology, and in particular to a subtitling processing method, device, and storage medium. [Background technology]

[0002] In the past, audio / video codec technology and data transmission technology during multimedia playback have always been at the core of multimedia technology, which often leads people to unconsciously ignore the value of subtitles. However, with the development of software technology, just like the road of web page technology, from plain text to rich text, the content to be carried is becoming more and more abundant, and the content that can be conveyed through subtitles is also becoming more and more.

[0003] In the subtitle control logic, each subtitle does not actually need to have an end time, and may not even need a start time (called superimposed subtitles in some specifications). Normal subtitles, unlike superimposed subtitles, must have at least one start time. Therefore, depending on whether a subtitle has an end time, the traditional method implements two logics, interweaving subtitles with end times and subtitles without end times, and processing them in two processing logics respectively, which makes the control logic relatively complex. Summary of the Invention [Problem to be solved by the invention]

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without any creative work fall within the scope of protection of the present application.

[0023] As shown in Figure 1, a flow chart of a subtitle processing method provided in a first embodiment of the present invention includes the following steps:

[0024] Step S101: A terminal obtains an original subtitle sequence, the original subtitle sequence including at least one first original subtitle, the first original subtitle being a subtitle with an end time.

[0025] In an embodiment of the present invention, an original subtitle sequence includes one or more original subtitles, each of which has a start time. Here, the one or more original subtitles include at least one first original subtitle. In an embodiment of the present invention, the first original subtitle refers to a subtitle with an end time. When an original subtitle sequence includes multiple subtitles, the multiple subtitles may include at least one first original subtitle and may also include at least one second original subtitle. In an embodiment of the present invention, the second original subtitle refers to a subtitle without an end time.

[0026] If an original subtitle sequence includes multiple original subtitles, the multiple original subtitles are arranged in order of their start times to form this original subtitle sequence, where the first original subtitle and the second original subtitle may be arranged in a staggered manner, although this is not a limitation of the embodiments of the present application.

[0027] Step S102: The terminal performs a splitting operation on the first original subtitle of the original subtitle sequence to obtain a first type subtitle and a second type subtitle.

[0028] In an embodiment of the present invention, after obtaining an original subtitle sequence, the terminal performs a division operation on a first original subtitle included in the original subtitle sequence. Note that in an embodiment of the present invention, if the original subtitle sequence includes multiple first original subtitles, the terminal may perform the division operation on each of all the first original subtitles included in the original subtitle sequence, or may perform the division operation on only some of the first original subtitles among all the first original subtitles, but the embodiment of the present invention is not limited thereto.

[0029] In an embodiment of the present invention, taking one of the first original subtitles as an example, when a terminal performs a splitting operation on the first original subtitle, a first type subtitle and a second type subtitle are obtained, where the first type subtitle and the second type subtitle are both subtitles without end time. The start time of the first type subtitle is the start time of the first original subtitle, and the subtitle type of the first type subtitle is the first type subtitle, which indicates that the first type subtitle contains the subtitle content of the first original subtitle. subtitle The first type subtitle is for rendering subtitle content into an image. The start time of the second type subtitle is the end time of the first original subtitle time. The subtitle type of the second type subtitle is a second type subtitle for indicating the rendering of the content without subtitles of the second type subtitle. subtitle and a background content clearing operation is performed.

[0030] For example, if the playback period of a first original subtitle is 5S to 10S and is named Sub[5,10], the start time of the first original subtitle Sub[5,10] is 5S and the end time is 10S. A splitting operation is performed on this first original subtitle to obtain a first type subtitle Sub1[5,*] and a second type subtitle Sub2[10,*], where * indicates no end time. The subtitle type of the first type subtitle Sub1[5,*] uses a content identifier and is a first type subtitle. The subtitle type of the second type subtitle Sub1[10,*] uses a cleanup identifier and is a second type subtitle. Table 1 shows a table of subtitle types provided in an embodiment of the present application. Note that this table shows only an outline of the first type subtitle and the second type subtitle. In actual applications, other types and quantities of subtitle types may be included, and this is not a limitation of the embodiment of the present application.

[0031] [Table 1]

[0032] Step S103: Generate a target subtitle sequence based on the first type subtitle and the second type subtitle.

[0033] In an embodiment of the present invention, the terminal performs a division operation on each of all or a part of the first original subtitles included in the original subtitle sequence, obtains first-type subtitles and second-type subtitles corresponding to each of the first original subtitles, and then generates a target subtitle sequence corresponding to the original subtitle sequence based on the first-type subtitles and second-type subtitles corresponding to each of all or a part of the first original subtitles.

[0034] Optionally, in an embodiment of the present invention, when the terminal performs the division operation on each of all first original subtitles included in the original subtitle sequence, the target subtitle sequence includes first type subtitles and second type subtitles corresponding to each of the first original subtitles of all the first original subtitles. If the original subtitle sequence further includes one or more second original subtitle sequences, the target subtitle sequence includes the one or more second original subtitle sequences, and the first type subtitles and second type subtitles corresponding to each of the first original subtitles of all the first original subtitles and the one or more second original subtitle sequences are arranged according to start time.

[0035] Optionally, in an embodiment of the present invention, when a terminal performs a division operation on each of a portion of first original subtitles included in an original subtitle sequence, a target subtitle sequence includes first-type subtitles and second-type subtitles corresponding to each of the first original subtitles of the first original subtitles. In this case, the target subtitle sequence also includes the remaining portion of first original subtitles for which the division operation has not been performed, and the first-type subtitles and second-type subtitles corresponding to each of the portion of first original subtitles for which the division operation has been performed in the target subtitle sequence and the first original subtitles for the remaining portion for which the division operation has not been performed are arranged in order of the start times of each subtitle. Optionally, when the original subtitle sequence further includes one or more second original subtitle sequences, the target subtitle sequence includes one or more second original subtitle sequences, and the first-type subtitles and second-type subtitles corresponding to each of the first original subtitles for which the division operation has been performed, the first original subtitles for the remaining portion for which the division operation has not been performed, and the one or more second original subtitle sequences are arranged in order of the start times of each subtitle.

[0036] In the first embodiment, a first original subtitle with an end time is analyzed from an original subtitle sequence, and a splitting operation is performed on the first original subtitle to obtain a first type subtitle and a second type subtitle without an end time, thereby finally generating a target subtitle sequence corresponding to the original subtitle sequence. Since all subtitles in the target subtitle sequence only have a start time, the control logic of the subtitles can be simplified.

[0037] 2 is a flow chart of a subtitle processing method provided in embodiment 2 of the present invention, which includes the following steps:

[0038] Step S201: A terminal obtains an original subtitle sequence, the original subtitle sequence including at least one first original subtitle, the first original subtitle being a subtitle with an end time.

[0039] In the embodiments of this specification, step S201 can be understood by referring to the content related to step S101 in embodiment 1, so it will not be described here.

[0040] Step S202 includes determining whether the first original subtitle satisfies a dividing condition.

[0041] In an embodiment of the present invention, after obtaining an original subtitle sequence, the terminal first checks each of one or more first original subtitles included in the original subtitle sequence to determine whether each first original subtitle meets the splitting condition.

[0042] Optionally, the division condition in this embodiment of the present invention may include the time interval between the end time of a first original subtitle and the start time of the next subtitle being greater than a predetermined time. That is, if the time interval between the end time of a first original subtitle and the start time of the next subtitle is greater than the predetermined time, the first original subtitle is determined to satisfy the division condition. For example, the predetermined time may be any value between 30 milliseconds and 50 milliseconds. If the predetermined time is set to 40 sm, the first original subtitle is determined to satisfy the division condition if the time interval between the end time of a first original subtitle and the start time of the next subtitle is greater than 40 sm.

[0043] Optionally, the splitting condition in the embodiment of the present application may include that the first original subtitle is the last subtitle in the original subtitle sequence, i.e., if a first original subtitle is the last subtitle in the original subtitle sequence, the first original subtitle satisfies the splitting condition.

[0044] Step S203: If the division condition is met, perform a division operation on the first original subtitle to obtain a first type subtitle and a second type subtitle.

[0045] In this embodiment of the present invention, the terminal performs a splitting operation on each first original subtitle that satisfies the splitting condition, and obtains a first type subtitle and a second type subtitle corresponding to each first original subtitle. Specifically, step S230 can be understood by referring to the relevant content of step S102 in embodiment 1, and therefore will not be described here.

[0046] Step S204: If it is determined that the splitting condition is not met, adjust the end time of the first original subtitle to obtain the first target subtitle, or adjust the start time of the next subtitle to obtain the second target subtitle, where the start time of the second target subtitle is the end time of the first original subtitle.

[0047] In this embodiment, if the first original subtitle does not satisfy the division condition, for example, if the time interval between the end time of the first original subtitle and the start time of the next subtitle shown in step S202 is less than a predetermined time, the first original subtitle is not divided but adjusted to obtain a first target subtitle, i.e., the end time of the first original subtitle that does not satisfy the division condition is adjusted to the start time of the next subtitle. Alternatively, if the first original subtitle does not satisfy the division condition, the first original subtitle is not divided but adjusted to obtain a second target subtitle, i.e., the start time of the next subtitle is adjusted to the end time of the first original subtitle.

[0048] In this embodiment, since the second type of subtitle is a background content clearing operation, if the time interval between the end time of the first original subtitle and the start time of the next subtitle is short, a splash screen is likely to occur when the background content clearing operation is performed. Therefore, for first original subtitles that do not satisfy this division condition, division is not performed, and the end time of the first original subtitle that has an end time is adjusted to be the same as the start time of the adjacent subtitle, that is, adjusted so that the adjacent subtitle starts when the first subtitle ends. Therefore, by connecting the first subtitle and the adjacent subtitle without any time difference on the time axis, a splash screen can be prevented.

[0049] A target subtitle sequence corresponding to the original subtitle sequence is generated based on the first type subtitle and the second type subtitle.

[0050] In the embodiments of this specification, step S205 can be understood by referring to the content related to step S103 in embodiment 1, so it will not be described here.

[0051] In the second embodiment, a first original subtitle with an end time is analyzed from an original subtitle sequence, and a splitting operation is performed on the first original subtitle to obtain a first type subtitle and a second type subtitle without an end time, thereby finally generating a target subtitle sequence corresponding to the original subtitle sequence, and all subtitles in the target subtitle sequence only have start times, which simplifies the subtitle control logic. Different from the first embodiment, the second embodiment also achieves the advantage of preventing splash screens.

[0052] 3 is a flow chart of a subtitle processing method provided in embodiment 3 of the present invention, the subtitle processing method includes the following steps:

[0053] Step S301: A terminal obtains an original subtitle sequence, the original subtitle sequence including at least one first original subtitle, the first original subtitle being a subtitle with an end time.

[0054] Step S302: Perform a dividing operation on the first original subtitle to obtain a first type subtitle and a second type subtitle.

[0055] Step S303: Generate a target subtitle sequence corresponding to the original subtitle sequence based on the first type subtitle and the second type subtitle.

[0056] In the embodiments of this specification, steps S301 to S303 can be understood by referring to the content related to steps S101 to S103 in the first embodiment, and therefore will not be described here.

[0057] Step S304: Determine the subtitle type of the currently broadcast subtitle, where the currently broadcast subtitle is any one of the subtitles in the target subtitle sequence.

[0058] Step S305: Obtain a target background content by rendering the currently broadcast subtitle according to the subtitle type of the currently broadcast subtitle.

[0059] In the embodiments of the present specification, when the subtitle type of the currently broadcast subtitles is the first type subtitles, the target background content is background content obtained by rendering the subtitle content of the currently broadcast subtitles, and when the subtitle type of the currently broadcast subtitles is the second type subtitles, the target background content is background content obtained by performing a background content clear operation.

[0060] Step S306: Compare whether the current playback progress time is longer than the start time of the currently broadcast subtitles.

[0061] Step S307: If the current playback progress time is longer than the start time of the currently broadcast subtitles, the target background content is displayed.

[0062] In the second embodiment, a first original subtitle with an end time is analyzed from an original subtitle sequence, and a splitting operation is performed on the first original subtitle to obtain a first type subtitle and a second type subtitle without an end time, thereby finally generating a target subtitle sequence corresponding to the original subtitle sequence, and all subtitles in the target subtitle sequence only have start times, which simplifies the subtitle control logic. Different from the first embodiment, the second embodiment also achieves the advantage of preventing splash screens.

[0069] In an embodiment of the present invention, taking one of the first original subtitles as an example, when a terminal performs a splitting operation on the first original subtitle, a first type subtitle and a second type subtitle are obtained, where the first type subtitle and the second type subtitle are both subtitles without end time. The start time of the first type subtitle is the start time of the first original subtitle, and the subtitle type of the first type subtitle is the first type subtitle, which indicates that the first type subtitle contains the subtitle content of the first original subtitle. subtitle The first type subtitle is for rendering subtitle content into an image. The start time of the second type subtitle is the end time of the first original subtitle time. The subtitle type of the second type subtitle is a second type subtitle for indicating the rendering of the content without subtitles of the second type subtitle. subtitle and a background content clearing operation is performed.

A splitting operation is performed on this first original subtitle to obtain a first type subtitle Sub1[5,*] and a second type subtitle Sub2[10,*], where * indicates no end time. The subtitle type of the first type subtitle Sub1[5,*] uses a content identifier and is a first type subtitle. The subtitle type of the second type subtitle Sub1[10,*] uses a cleanup identifier and is a second type subtitle. Table 1 shows a table of subtitle types provided in an embodiment of the present application. Note that this table shows only an outline of the first type subtitle and the second type subtitle.
