Design And Implementation Of A Multi-screen Interactive Media Player System For Home

With the rapid development of Internet technology,the use of smart phones,home computers,tablets and smart TVs has become more common,making the form of home entertainment richer and smarter.In the home entertainment office,the TV has the advantage of large screen,the mobile phone has the advantage of being convenient to use,and the advantage of the computer is that the performance is strong.They all have their own advantages,but they can't communicate with each other.When users want to combine the convenience features of mobile phones,the big screen features of smart TVs and the high-performance features of home computers in the family living room environment,they can't be satisfied.In order to combine mobile phones,home computers and smart TVs to achieve interoperability and resource sharing,thereby obtaining a better multimedia viewing experience and bringing convenience to users,a multi-screen interactive media player for home is proposed.By implementing the system,the user can push the media resources of the home computer or the mobile phone to the smart TV for remote playback,and at the same time,the media playback can be remotely controlled on the mobile phone,and the user can also screen the computer screen to the television.The system includes five modules,the network communication module is the communication basis of the whole system,and the transmitted information is encrypted;the media server module implements the media resource management,the media resource access service,and the RTSP streaming service.In the implementation process of RTSP,the constant multiplicative growth and constant multiplicative reduction control algorithm is adopted,which can dynamically adjust the transmission rate of the data stream;the media player module implements image loading,audio lyrics synchronization loading and media playback control services.And this part integrates VLC open source player to support multiple media formats;the media controller module implements multiple control interfaces for requesting media server services and media player services;smart recommendation and device interaction modules has realized Smart recommended subtitles or lyrics,TV application management,computer screen projection to TV and Bluetooth speaker control management,and in the smart recommendation subtitles or lyrics,a recommendation algorithm based on forgetting function and popularity is proposed toimprove the accuracy of subtitle or lyric matching.Finally,this thesis conducts functional tests,performance tests,and compatibility tests on various functional modules of the system.The test results show that the system can realize the interconnection and multi-screen interaction of mobile phones,home computers and smart TVs,and achieve the design goal.
