Problems solved by technology
[0020] The technical solution recorded in this prior art cannot achieve real-time audio, video and subtitle synchronization, and the subtitles and sign language produced by this solution cannot be synchronously added to the correct time axis of the live video even if the error offset is added.
[0021] In addition, the existing online live subtitles are all evolved from the addition of subtitles in the field of broadcasting and television. Subtitles are added at the signal terminal through hardware subtitle equipment, resulting in the inability of Internet subtitles to achieve real time synchronization between subtitles and video and audio.

The present invention discloses a streaming media and caption instant synchronization display and matching processing method, device and system. Wherein the method comprises: performing encoding of the video and audio data in a collected streaming media, and sending the video and audio data to a live server; obtaining the caption data corresponding to the video and audio data, and sending the video and caption data to the live server; the caching the encoded video and audio data through the live server according to a presetting delay time, forming a caption layer according to the caption data and caching the caption layer, establishing a synchronization coupling relation between the caption layer and the video and audio data, and sending the caption layer and the video and audio data; and mixing the received caption layer and the video and audio data having a synchronization matching relation to form streaming media information, and distributing the streaming media information to a network node for outputting so as to ensure the synchronized and instant display of the video and audio data and the caption layer and improve the matching accuracy of the video and audio data and the caption layer.
Description
technical field [0001] The present invention relates to the technical field of streaming media live streaming, in particular to a method and device for real-time synchronous display of streaming media and subtitles, a method and device for synchronous matching processing of streaming media and subtitles, and a system for real-time synchronous display of streaming media and subtitles. Background technique [0002] With the rapid promotion of the Internet + mode and the development of live streaming media, subtitle translation has greatly reduced visual interference and improved the synchronization level compared with simultaneous interpretation. At present, in the field of global Internet streaming media live broadcasting, most of them adopt the mode of independent video playback and independent translation of subtitles. The subtitles and videos cannot achieve real-time synchronization of audio, video and subtitles, and a transparent layer is placed on the video for subtitle d...
