Multi-screen interaction video and audio content switching method and media player

Abstract

The invention discloses a multi-screen interaction video and audio content switching method and a media player. The method comprises the following steps: when a screen needs to be switched, connecting source equipment with target equipment; generating video and audio content switching data by use of the current playing position of the recorded current played video and audio, original compressed data stream from the previous key frame of the current playing frame to the tail part of the current playing frame as well as parameters and control information required by coding the current played video and audio; transmitting to the media player of the target equipment according to a multi-screen interaction protocol; switching the data by the media player of the target equipment according to the received video and audio content; and according to the current playing position, continuously playing the video and audio from the previous key frame of the current playing frame. According to the invention, multi-screen interaction can be flexibly realized among all equipment, video and audio pictures can be seamlessly switched, the target equipment is continuously remotely controlled on the source equipment to play, the source equipment is switched back to continuously play, low network bandwidth is occupied, and convenience is provided for users.

Description

technical field [0001] The invention relates to the technical field of multi-screen interaction, in particular to a multi-screen interactive audio and video content switching method and a media player supporting multi-screen interaction. Background technique [0002] With the development of network communication technology and multimedia technology, smart TVs, smart phones, and tablet computers have increasingly entered people's daily lives. Moreover, people hope to flexibly share and switch pictures, audio and video content between smart TVs, smart phones, and tablet computers, for example, switching a video watched on a mobile phone to continue playing on a TV. [0003] At present, there are already some methods to realize such a function. One method is to use screen copying technology, for example, to completely copy the content of the current mobile phone screen and transmit it to the TV screen. However, the use of this technology to realize the transmission of video im...

Problems solved by technology

However, the use of this technology to realize the transmission of video images requires the computing power of the mobile phone to be powerful enough, which takes up a lot of bandwidth resources, and it is almost impossible or very expensive for high-definition video

[0004] Another method is to use file transfer technology to transfer the compressed file of the media being played. The limitations of this technology are: first, it cannot be automatically switched to the current playback position to start playing when it is transferred in the form of a file. Second, if you are playing streaming media on the network, you may not have permission to perform or cannot complete file transfer in real time
