Design And Implementation Of Video Interaction And Wireless Control System Based On Android

In recent years,Ansroid system smartphone has been developing rapidly.Digital high definition television occupies the important position.With the characteristics,such as high speed,flexibility and simpleness to manage,Wi Fi has been grow up to be the current main stream technology and the most common way of Internet access.However,Android smartphone can only enjoy the resources and services from itself,and most televisions can also only watch the traditional television programs.These devices provide users with the services and functions in a single and there is no link between each other.Therefore,the research on video interaction and wireless control system between the mobile phone and the television,has the practical significance and application value for the function expansion of the mobile phone and television.Firstly,this paper introduced the system scheme selection,Android development and the relevant technology of video interaction.Then according to the current reality of most TV that does not have a networking capability,by using the I.MX536 coreboard as the foundation,the paper gived the hardware design of video interaction box.The design of video interaction box mainly includes the design of peripheral interface,the conversion design of VGA to HDMI,as well as the modification and transplantation related to Android system driver.In addition,the paper also analysed and studied on the basic principles of video interaction technology DLNA protocol,then integrated receiver and server in the video interaction box,also integrated server,player and controller in the Android mobile phone control terminal,based on the characteristics of Android system.The hardware test shows,the video interaction box designed in the paper realized the function that user can control wireleely the video interaction box to browse and play the media files with the mobile phone,and support to delivery media files from the mobile phone to the television.The system can also expand the function of projector with the video interaction box designed in this paper.The paper makes the fact that PDF document is converted to images on the pnone and the user delivery the images to big screen possible.
