一种基于嵌入式平台屏幕内容分享系统的设计与实现
Design and implementation of a screen sharing system based on embedded platform
摘要
Abstract
In order to share screen among intelligent devices with high quality and low band width,a screen sharing system based on embedded system has been designed and implemented,which consists of a cross-platform client and server.For the purpose of reducing bandwidth and improving screen quality,a self-adaptive method based on scene recognition is proposed,which could recognize the application scene intelligently and adjust H.264 code rate according to network congestion state and application context.On the other hand,the server has been deployed on embedded board.For the server side,a solution based on multiple threads has been proposed,which consists of main thread, message receiving thread,decode thread and display thread.Every thread focuses on their own task, which could improve the robustness and coupling dramatically.Experiment results show that the pro-posed screen sharing system could support screen sharing between PC and embedded display system with 720 p high resolution.And this solution has the advantages including real time,low-bandwidth and low cost.关键词
