Problems solved by technology
[0004] The first is to fix the subtitles to the video screen, so that the subtitles and the video screen are combined into one screen: this method can make the subtitles and video have good synchronization performance, but the user cannot adjust the subtitles during the video playback process. Modifying the subtitles, that is, the subtitles cannot be enlarged or reduced, or the operation of changing the display mode has brought inconvenience to the user
[0005] The second is to embed the subtitles into the video stream in the form of characters: although the user can modify the subtitles with this method, the display of the subtitles needs to rely on the local character library. Once the character library is missing, the subtitles will not work normally. display of
[0006] The third is to provide subtitles to the display unit in the form of independent files: this method not only needs to rely on the local character library, but also because the subtitles and video streams transmitted in independent files do not belong to the same file, it is very easy cause loss or tampering of subtitles

Embodiment Construction
[0062] An embodiment of the present invention provides a method for processing subtitles, through which the playback effect of displaying subtitles on a player can be realized. The following combination figure 1 The embodiment of the invention is described in detail:
[0063] 101. The generation unit generates subtitle parameters;
[0064] The generation unit may generate subtitle parameters corresponding to subtitles and subtitle display effects according to user operations.
[0065] 102. The generation unit generates a subtitle image corresponding to the subtitle parameter;
[0066] The generation unit renders the generated subtitle parameters into a subtitle image of a specified style, and the subtitle parameters correspond to the subtitle image.
[0067] 103. The generation unit generates a subtitle stream in a video format according to the subtitle image;
[0068] The generation unit encodes the subtitle image to generate a subtitle stream in video format.
[0069] T...

The embodiment of the invention discloses a method and a device for processing subtitle and subtitle display system. The method disclosed by the embodiment of the invention comprises the following steps: a generating unit generates subtitle parameters; the generating unit generates subtitle images corresponding to the subtitle parameters; the generating unit generates subtitle stream in a video format according to the subtitle images; the generating unit combines the video stream and the subtitle stream to generate composite stream to allow a transmitting unit to read the composite stream and to send the stream to a display unit; then, the display unit displays the subtitles corresponding to the subtitle stream. As the generating unit can generate the subtitle parameters according to operation of a user, the display unit can display the subtitle playing effect; furthermore, the playing process is free from relying on a local character repertoire, so that the situation that the subtitle cannot be displayed normally will not happen. The subtitle stream and the video stream belong to the same file, so that the subtitle stream is not easy to lose or manipulate, and the safety of the subtitle stream transfer is improved.
Description
technical field [0001] The embodiment of the present invention relates to the field of multimedia technologies, and in particular to a subtitle processing method, device and subtitle display system. Background technique [0002] When a user watches a video through a computer, a television, or a handheld device, it is necessary to display the video content in the form of subtitles in order to facilitate the user to clearly understand the content of the video. [0003] In the prior art, there are roughly three ways to process subtitles: [0004] The first is to fix the subtitles to the video screen, so that the subtitles and the video screen are combined into one screen: this method can make the subtitles and video have good synchronization performance, but the user cannot adjust the subtitles during the video playback process. Subtitles are modified, that is, the subtitles cannot be enlarged or reduced, or the operation of changing the display mode has brought inconvenience ...
