Problems solved by technology

[0004] However, at present, this method generates video streams for video and files separately, and then the acquisition end transmits the video streams generated by the video and the video streams generated by the files to the server, and then the playback end downloads the video streams generated by the video and the video generated by the files from the server. The live broadcast technology for stream playback, because the video stream generated by the video and the video stream generated by the file need to be downloaded during transmission, and the video stream generated by the file contains a lot of redundant information, so it consumes a lot of traffic, and the synchronization operation When, because the video stream generated by the video and the video stream generated by the file need to be played synchronously, the synchronization operation is complicated and the error is high

Abstract

The invention discloses a method and an apparatus for synchronously displaying a file in live video. A specific embodiment of the method comprises the steps of enabling a collection end to obtain a corresponding relation between a video frame of a streaming media data and a file unique identification, performing coding based on the file unique identification to obtain a synchronous field, adding the synchronous field to an extended field of the video frame, and uploading the streaming media data after being added with the synchronous field to a server; and enabling a playing end to download the streaming media data from the server, detecting whether synchronous fields exist in expanded fields of each video frame in the streaming media data or not, responding to synchronous fields existing in the expanded fields, downloading files corresponding to the synchronous fields from the server, and synchronously displaying the video frames and files of the synchronous fields in playing the streaming media data. By adoption of the embodiment, the required flow in the live video is reduced; and in addition, a simple synchronous method and relatively low error rate are achieved.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a method and device for synchronously displaying files during live video broadcasting. Background technique [0002] With the development of mobile networks, mobile network live broadcast services have also received more and more attention. Today, when the live broadcast business is relatively homogeneous, how to break through the limitations of traditional video live broadcast and bring more derivative functions and interactive experiences has become a difficult problem. [0003] In the prior art, a live broadcast method of synchronously displaying files in a live video broadcast has been derived. The realization of this live broadcast method is that the acquisition end generates video streams for video and files (such as pictures, slideshows or graffiti, etc.), and then the acquisition end transmits the video st...
