Abstract: A multi-screen video display method and system, and a playing end and a storage medium. The multi-screen video display method comprises: a slave playing end decoding a preset number of video frames and storing same, sending a ready signal to a master playing end; the slave playing end receiving a start playing notification of the master playing end and starting to play video frames; the slave playing end receiving information of a frame to be displayed of the master playing end, calculating an adaptive synchronization threshold value range according to the information of the frame to be displayed of the master playing end; the slave playing end comparing a display timestamp of a frame to be displayed of the slave playing end with the calculated adaptive synchronization threshold value range, to determine whether a playing progress of the slave playing end is synchronized with that of the master playing end.

Abstract: Provided are a method for realizing a video conference, and a terminal and an SIP gateway. The method for realizing a video conference is applied to a WebRTC terminal, and comprises: performing interaction of SIP signaling with an SIP gateway by means of an SIP account, so as to establish a video conference connection with an SIP terminal, wherein SIP signaling between the WebRTC terminal and the SIP gateway is transmitted by means of a WebSocket protocol, and the WebRTC terminal can parse the received SIP signaling transmitted by means of the WebSocket protocol; and sending a locally collected video stream, and/or receiving a video stream of the SIP terminal, and playing same by means of a browser.
