With the rapid development of the mobile internet, videos show the trend of moving, fragmenting and socializing. At present, information transmission in a video mode becomes one of the mainstream modes of information transmission, and a user needs to share currently viewed content to others through a social platform while watching a video. Generally, a user extracts a wonderful segment seen on a screen on the intelligent terminal and publishes the wonderful segment to a social platform to share with friends, so that more users are attracted to watch long videos by wonderful short videos and are guided to a large television screen, and a transmission closed loop of large and small screens between the television and the intelligent terminal is formed. Through big data analysis, can acquire watching and propagating hobby of user to can further improve accurate service level, promote user's liveness.
In actual operation, when a currently watched live television video clip is shared to others on an intelligent terminal, a situation that a time deviation exists between the watched live television video clip and a sharing clip completed based on a source station stream often occurs. The main reason for the time deviation is that when a live video program is watched, a live video stream for watching and a source station stream for sharing are not the same stream, and the corresponding technologies of the streams are different. For example, there are Live streams using hls (http Live streaming) or RTMP (Real Time Messaging Protocol), and there are Live streams using P2P (Peer To Peer network), and so on; the source station stream is likely to be inconsistent with the technology used by the live stream, and there is uncertainty in the delay of each live stream. This results in inaccurate segments captured by the source station stream, and often occurs in a situation with a large time deviation.
Currently, the time offset is mainly eliminated by means of manual periodic calibration. The method has high treatment cost and great difficulty, and is not beneficial to popularization and use.
