Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Currently, many video content providers (such as BBC, Netflix, HBO) use time sequential text markup language (TTML) as subtitles. However, because the sequential text markup language adopts a relatively bloated XML format, some current browsers do not support the TTML subtitles, such as google Chrome browser. The browser has poor support, which causes embarrassment of TTML subtitles originally designed for Internet media at the Internet end.
In order to solve the problem, the scheme adopts the imscJS open source framework to realize the rendering of the TTML subtitles. imscJS is used to render IMSC text and image profile documents as JavaScript libraries in HTML. Firstly, downloading open-source imscJS.js; secondly, introducing js into a web page by the browser; then, writing a script for initializing imscJS; and finally, analyzing and rendering the caption resource of application/TTML + xml type in the < Track > tag, thereby realizing the effect of outputting the TTML caption in the browser. The parsing and rendering of the TTML subtitles is achieved using open source imscJS. In this way, pages in HTML5 may be provided with the ability to render TTML subtitles without relying on a browser or other underlying implementation. The following examples are intended to illustrate the details.
Example one
Fig. 1 is a flowchart of a subtitle processing method according to an embodiment of the present application, where the method is applicable to a situation where a browser outputs a sequential text markup language, and the method may be executed by a computer device or a smart television, where the computer device or the smart television can run an application that outputs an HTML page, where the application may be a browser, and the method specifically includes the following steps:
and step 110, acquiring a text resource of the time sequence text markup language (TTML) subtitles.
Web pages containing time sequential text markup language (TTML) subtitles can be written using hypertext markup language (html). The hypertext markup language describes tags contained in a web page containing time-sequential text markup language (TTML) subtitles and the content of each tag. The method comprises a label for displaying the caption, wherein the label records the address of the text resource of the time sequence text markup language TTML caption. And accessing the address to obtain the text resource of the TTML subtitle. Optionally, the text resource of the time-series text Markup Language TTML subtitle is written in an Extensible Markup Language (XML) format.
And step 120, determining at least one group of subtitle output information according to the text resources of the TTML subtitles.
Wherein each set of subtitle output information includes a subtitle output time and subtitle content. The text resource of the time sequence text markup language TTML caption comprises at least one group of caption output information. Each set of subtitle output information includes a subtitle output time representing a time at which a subtitle is output and subtitle content.
Since the caption is combined with the multimedia playing, the caption output time is associated with the playing duration of the multimedia playing, or associated with one or more frame pictures of the multimedia. When the caption output time is associated with the playing time of the multimedia playing, the caption output time is the multimedia playing time, and when the multimedia playing reaches the playing time, the caption content is output. When the caption output time is associated with one or more frame pictures of the multimedia, the caption output time is the multimedia playing duration, and when the multimedia is played to the playing duration, the caption content is output.
Optionally, the subtitle output information includes a subtitle output time and subtitle content. The subtitle output information may include a plurality of subtitle content information pairs, each subtitle content information pair including a subtitle output time, subtitle content, and a subtitle style. The subtitle is divided into a plurality of pairs of subtitle content information according to output time. Illustratively, the pair of subtitle content information is (first second, a), indicating that in the first second of multimedia data playback, the subtitle content is played as a.
Optionally, step 120, determining at least one group of subtitle output information according to the text resource of the TTML subtitle may be implemented in the following manner:
and analyzing the text resource of the TTML caption according to the XML grammar to obtain at least one group of caption output information.
The text resources of the chronological text markup language (TTML) subtitles may be text edited using an XML grammar. The caption output information can be marked in advance according to XML grammar to obtain the text resource of the time sequence text markup language TTML caption in the XML format. Step 120, when the text resource of the time sequence text markup language TTML subtitle in the XML format is obtained, analyzing the text resource according to the XML grammar to obtain at least one group of subtitle output information. The XML grammar has universality, and therefore reliability of subtitle output information identification is achieved.
Step 130, creating a subtitle object of the browser according to the target subtitle output information.
The target caption output information is any one group of caption output information in at least one group of caption output information, the target caption output information comprises target caption content and target caption output time, and the caption object is used for triggering a target caption event at the target caption output time so as to output the target caption content in an HTML page according to the target caption event in a browser.
One subtitle object is created for each set of subtitle output information. And configuring a target subtitle object to start a target subtitle event at the target subtitle output time according to the target subtitle output information, wherein the target subtitle event can be recognized by the browser. The target caption event is used to output target caption content in the HTML page at a target caption output time.
The HTML page includes a tag for displaying a subtitle, which is also called a subtitle display tag. Converting the target caption content into a caption text conforming to HTML; embedding the subtitle text of HTML into the tag for displaying subtitles; and outputting the subtitle text of the HTML according to the subtitle display tag.
Optionally, the page may be an HTML page, and optionally, the page is an HTML5 page. HTML5 is a language description way to build Web content. HTML5 is the next generation standard for the internet and is a language way to build and present internet content. The HTML5 page is an HTML page described using the HTML5 language. The syntax of the page is in the hypertext markup language HTML.
The subtitle processing method provided by the embodiment of the application obtains text resources of a time sequence text markup language (TTML) subtitle; determining at least one group of subtitle output information according to the text resources of the TTML subtitles; and creating a subtitle object of the browser according to the target subtitle output information, wherein the subtitle object is used for triggering a target subtitle event at the target subtitle output time so as to output target subtitle content in the HTML page according to the target subtitle event in the browser. Compared with the problem that the current browser cannot play the time sequence text markup language subtitles and is poor in compatibility, the method and the device for playing the time sequence text markup language subtitles can determine subtitle output information according to the text resources of the time sequence text markup language letters after acquiring the text resources of the time sequence text markup language subtitles, create the subtitle objects of the browser according to the target subtitle output information, and enable the created subtitle objects to trigger the target subtitle events at the target letter output time. And the browser outputs the target subtitle content in response to the target subtitle event, so that the target subtitle content is output in the HTML page. And creating a subtitle object which can be supported by the browser according to the text resource of the time sequence text markup language, wherein the browser can respond to a target subtitle event triggered by the subtitle object, and then playing the time sequence text markup language subtitle in an HTML page, so that the compatibility of the browser is improved.

Js file content can also be read. The webpage designer can edit the imscJS.js file under the imscJS.js frame. When the browser outputs the HTML page, the imscJS.js frame is previewed and loaded, so that the content of the imscJS.js file can be read under the frame, and the TTML subtitles in the HTML page are analyzed and rendered. When the page contains the TTML subtitles, introducing an imscJS.js file into the page so as to obtain a script edited by a JavaScript language recorded in the imscJS.js file.
As a further description of the above embodiment, before step 110, the method further includes: and generating a subtitle display area in the HTML page according to the subtitle display tag in the browser. Accordingly, the step 130 of outputting the caption content in the HTML page according to the caption event in the browser may be implemented as follows: converting the target caption content into a target caption text conforming to HTML; and embedding the target subtitle text into the subtitle display tag so that the browser outputs the target subtitle content in the subtitle display area according to the target subtitle text in the subtitle display tag. When implemented in the above manner, the method comprises:
and step 210, generating a subtitle display area in the HTML page according to the subtitle display tag in the browser.
From the code of the HTML page, a subtitle display tag for displaying a subtitle can be known. When an HTML page is initialized, a plurality of regions are created according to the code of the HTML page, with different regions acting differently according to the content of the code tags. Alternatively, a < div > tag may be used as a subtitle display tag. And when the browser acquires the tag according to the code of the HTML page, a subtitle display area is created in the HTML page.
And step 220, acquiring a text resource of the time sequence text markup language (TTML) subtitle.
The execution of step 220 may refer to the description of step 110.
Optionally, step 220, obtaining the text resource of the time-series text markup language (TTML) subtitle may be implemented in the following manner:
acquiring a link address of a text resource of the TTML through a track tag, wherein a subtitle display tag comprises the track tag; and acquiring the text resource of the TTML subtitle according to the link address.
In the code of the HTML page, the Track tag may be a < Track > tag in HTML, which is nested within a subtitle display tag. The < Track > tag stores a link address, which is an address of a text resource of the TTML. After the link address of the text resource of the TTML is obtained, the text resource of the TTML subtitle can be downloaded by accessing the link address.
The designer of the HTML page can configure different subtitles for the HTML page by changing the link address in the < Track > tag. Furthermore, designers of the HTML webpage can modify the text resource of the TTML subtitle and move to adjust the subtitle in the HTML page accessing the text resource of the TTML subtitle, so that the subtitle modification efficiency is improved.
The process of step 230 can be performed as described with reference to step 120.
Step 240, creating a subtitle object of the browser according to the target subtitle output information.
The target caption output information is any one group of caption output information in at least one group of caption output information, the target caption output information comprises target caption content and target caption output time, and the caption object is used for triggering a target caption event at the target caption output time.
The execution of step 240 can be as described with reference to step 130.
Further, the target subtitle output information includes a target subtitle style. Accordingly, step 240, creating a subtitle object of the browser according to the target subtitle output information, may be implemented by:
and creating a target subtitle object according to the target subtitle output information, wherein the target subtitle object is used for triggering a target subtitle event at the target subtitle output time, so that the browser can output target subtitle content in a target subtitle mode in the HTML page according to the target subtitle event.
Optionally, the subtitle output information includes a subtitle output time, subtitle content, and subtitle style.
The subtitle output information may include a plurality of subtitle content information pairs, each subtitle content information pair including a subtitle output time, subtitle content, and a subtitle style. The subtitle is divided into a plurality of pairs of subtitle content information according to output time. Illustratively, the pair of subtitle content information is (first second, a), which means that in the first second of multimedia data playing, the subtitle content is a and the subtitle style is a.
The TTML subtitle can mark not only the output time and content of the subtitle but also the style of the subtitle. And if the target subtitle output information comprises a target subtitle style, triggering a target subtitle event by the created target subtitle object at the target subtitle output time, wherein the subtitle event comprises rendering the target subtitle content according to the target subtitle style.
According to the embodiment, the subtitles in the HTML page can be rendered according to the style characteristics of the TTML subtitles, so that the subtitle styles are enriched, and the subtitle visual effect is improved.
Step 250, when the target caption event is triggered, converting the target caption content into a target caption text conforming to the HTML.
Optionally, the ISD is created when a target caption event is triggered. ISD is the HTML representation of the subtitle style. And assigning the ISD according to the target subtitle content and the target subtitle style conversion so as to obtain a subtitle text conforming to the HTML. And transferring the subtitle text conforming to the HTML into the subtitle display tag, so that when the browser runs the page, the subtitle text is output according to the subtitle text conforming to the HTML transferred into the subtitle display tag.
And step 260, embedding the target subtitle text into the subtitle display tag, so that the browser outputs the target subtitle content in the subtitle display area according to the target subtitle text in the subtitle display tag.
The target caption text conforms to the HTML syntax, and optionally, the assigned ISD may be used as the target caption text. And embedding the target subtitle text into a subtitle display tag of the HTML page code. When the HTML page is displayed according to the HTLM page code, the target subtitle text is output in the subtitle display area.
Further, after outputting the target subtitle content in the subtitle display area according to the target subtitle text in the subtitle display tag in the browser, in other words, after outputting the target subtitle content in the subtitle display area according to the target subtitle text in the subtitle display tag in the browser, the method further includes:
and deleting the target subtitle text in the target subtitle display label.
When there are a plurality of subtitle output information, a plurality of target subtitle events are generated. The output time corresponding to each target subtitle event is different. And after a certain target subtitle text is output, if the next target subtitle event of the target subtitle event corresponding to the target subtitle text is triggered, deleting the target subtitle text. And migrating the target caption text corresponding to the next target caption event into the target caption display label. And deleting the target subtitle text in the target subtitle display label in real time to realize the alternate playing of the subtitles.

the method comprises the following steps: js is loaded in the output device of the HTML page.
And (3) downloading the latest version of the imscJS through https:// github.com/sandflow/imscJS, and configuring the imscJS architecture.
Step two: from the code of the HTML page, a subtitle display tag (< div > tag) is created for which the subtitle is rendered blank, and the display of the subtitle will be implemented within the div.
When the HTML page is output, the previously edited imscjs. According to the JavaScript statement described in the document, the following steps are executed: and acquiring the URL address of the TTML subtitle text through a Track tag < Track > contained in the code of the HTML page, and downloading the text resource of the TTML subtitle.
Step three: parsing and rendering TTML subtitles according to records of imsc.JS files
3.1 analyzing the text resource of the TTML caption to obtain at least one group of caption output information. And analyzing information such as time, caption content, caption style and the like according to the TTML caption file in the XML format.
3.2 creating the subtitle object of the browser according to the target subtitle output information. And generating a subtitle object supported by the browser according to the acquired subtitle output information. When the subtitle object outputs multimedia data, a target subtitle event is triggered when the target subtitle output time is reached.
3.3 when the target caption event is triggered, the ISD is created. And assigning the ISD according to the subtitle output information to obtain a target subtitle text conforming to the HTML.
3.4 rendering subtitles. And 3.3, embedding the target subtitle text generated in the step 3.3 into div of a subtitle rendering area, and presenting a rich subtitle effect.
3.5 clear subtitles. When the browser triggers a subtitle end event, the HTML elements in the div of the subtitle rendering area are emptied.
3.6, the current caption event is ended, the next caption event is waited to start, and the steps 3.3, 3.4 and 3.5 are repeated.
The subtitle processing method provided by the embodiment of the application obtains text resources of a time sequence text markup language (TTML) subtitle; determining at least one group of subtitle output information according to the text resources of the TTML subtitles; and creating a subtitle object of the browser according to the target subtitle output information, wherein the subtitle object is used for triggering a target subtitle event at the target subtitle output time so as to output target subtitle content in the HTML page according to the target subtitle event in the browser. Compared with the problem that the current browser cannot play the time sequence text markup language subtitles and is poor in compatibility, the method and the device for playing the time sequence text markup language subtitles can determine subtitle output information according to the text resources of the time sequence text markup language letters after acquiring the text resources of the time sequence text markup language subtitles, create the subtitle objects of the browser according to the target subtitle output information, and enable the created subtitle objects to trigger the target subtitle events at the target letter output time. And the browser outputs the target subtitle content in response to the target subtitle event, so that the target subtitle content is output in the HTML page. And creating a subtitle object which can be supported by the browser according to the text resource of the time sequence text markup language, wherein the browser can respond to a target subtitle event triggered by the subtitle object, and then playing the time sequence text markup language subtitle in an HTML page, so that the compatibility of the browser is improved. The development work and the platform adaptation amount can be effectively reduced through the imscJS. Meanwhile, the latest TTML standard can be better supported, and the TTML subtitles meeting the Internet requirements at the beginning of design are better met.
