[0039] The database 11 is used to preset multiple broadcast styles of aerial subtitles;

[0040] The subtitle attribute setting unit 12 is used to set the attribute of the subtitle, and the attribute includes the mapping relationship between the subtitle on the fly and the broadcast style.

[0041] Then, when the subtitle playout module 2 is used to play out subtitles, according to the mapping relationship, the corresponding subtitles will be played out according to a predefined playout style.

[0042] Among them, the diversified broadcast styles can highlight fonts, for example, some words can be highlighted by changing fonts, colors, sizes, and bolding. Diversified broadcast styles can also be replaced by various styles such as pictures or animations. For example, the word "heart" can be replaced by a dynamic heart-shaped animation, or the word "happy" can be replaced by a smiling face. pictures, etc.

[0043] The playout style can be stored in the database in the form of a file. If the broadcast style is font highlighting, you can store the fonts to be highlighted in the form of picture files, of course, you can also not store them in the form of files, but set them in the way of attribute definition; and replace the text with pictures or animations The broadcast style, its picture or animation itself exists in the form of a file.

[0044] Subtitle creators can use the subtitle attribute setting unit 12 to set attributes for the subtitle being produced according to various broadcast styles in the database 11 . If the broadcast style exists in the form of a file, a mapping relationship between subtitles and files needs to be established.

[0045] Usually, the subtitle file header information data includes multiple subtitle sections (Section), each subtitle section includes the content and display information of a section of subtitle, and one section contains multi-screen subtitles. Subtitles are displayed sequentially in units of screens, and each screen can contain multiple subtitle blocks, and each subtitle block uniformly defines display attributes such as font, font size, color, and position through subtitle block parameters.

[0046] When defining the mapping relationship between subtitles and playback styles, it can be realized by setting subtitle block parameters. The font of a whole sentence can be set to be highlighted, and a certain word in a whole sentence can also be set to be replaced and displayed with animation, all of which can be completed by the subtitle producer using the subtitle attribute setting unit 12.

[0047] After the subtitle production module 1 completes the production of the subtitle, it can be transmitted to the subtitle broadcast module 2 for broadcasting. When the subtitle broadcasting module 2 is broadcast, the screen scrolls from right to left. If some subtitles are set with styles such as font highlighting and animation display, they will be played according to the set style.

[0048] To sum up, the subtitles produced by the subtitle machine greatly enrich the broadcasting effect of subtitles and meet the application needs of some special scenarios. For example, in the subtitles broadcasting the stock market information, the ups and downs information can be prominently broadcast to remind the viewers to pay attention. Or in some lyrics, some lyrics are highlighted. For another example, when playing the weather forecast, the word "cloudy" can be replaced with a picture of a cloud, and the word "heavy rain" can be replaced with an animation of rain, so that the display is more vivid and easier to be accepted by the audience.

Example Embodiment

[0049] Embodiment two:

[0050] refer to figure 2 , is a structural diagram of a subtitle machine for performing diversified subtitle broadcasting according to Embodiment 2 of the present invention.

[0051] As described in Embodiment 1, the subtitle machine includes a subtitle making module 1 and a subtitle playing module 2, wherein the subtitle making module 1 includes:

[0052] The database 21 is used to preset multiple broadcast styles of aerial subtitles;

[0053] The subtitle attribute setting unit 22 is configured to set the attribute of the subtitle, and the attribute includes the mapping relationship between the subtitle on the fly and the broadcast style.

[0054] Then, when the subtitle playout module 2 is used to play out subtitles, according to the mapping relationship, the corresponding subtitles will be played out according to a predefined playout style.

[0055]The differences between this embodiment and Embodiment 1 are:

[0056] The subtitle attribute set by the subtitle attribute setting unit 22 also includes whether to broadcast diversified subtitles on the fly; if not, the subtitle playout module 2 plays out according to the original playout style of the subtitle.
