摘要
针对多屏互动中移动端与显示端必须同时显示且无法回控的问题,提出一种基于AOA协议和Android平台的异屏互动系统的设计方法。链路模块采用双链路,解决数据安全的问题;实时传输协议交互,实现实时、高效、准确的多媒体数据传输;回控链路采用用户输入回发通道,解决安卓系统封闭回的问题。测试表明,设计的异屏互动系统可在安卓手机上长时间运行,具有实时性和稳定性的特点。
Aimed at the problem that mobile terminal and display terminal must display at the same time and cannot control back in multi-screen interaction.A method of different screen interaction system based on AOA protocol and Android is proposed.Double links is adopted in the link module to solve the problem of data security.Real-time Transport Protocol(RTP)interaction realizes real-time,efficient and accurate multimedia data transmission.User Input Back Channel(UIBC)is adopted in the back-control link to solve the problem of Android system closed back.The results show that the different screen interactive system designed in this paper can run on Android phone for a long time,with the characteristics of real-time and stability.
