Real-time Transmission And Control Based On Embeded Dual System Of Remote DV

The content of this thesis is to realize the transmission andcontrol of the remote DV,using mobile phone. The mobile phone will beused as a controler to control the remote DV to take a photo or recorda video and it can get the real-time view of the DV. The thesis is basedon a project. The author of this thesis mainly responsible for the partof building the remote control platform, as well as video transmission.Thedevelop board is A5S platform of the Ambralla Company. wifi communicationhardware is AR6003chip provided by the Athros company.The author’sdesign ideas are as flowers:1) Use wifi chip in the development board to achieve automaticallyassigns IP addresses to the mobile phone. In short, the camera is arouter. It assigns an ip address to the mobile phone to achieve theconnection.2) Build the web server and design the web page of the develop board.Themobile phone will use web page to access the camera.3) The development board is a dual system-the Uitron and Linuxsystem. The Uitron system is used for the basic function of the cameralike photo and video. The linux system is used for the stream out port.Weuse IPC for the communication of Uitron system and linux system.4) Use hls(HTTP live streaming) protocol for streaming out. Get the image flow from the sensor and cut it to ts frames flow and use plist forframes control.After a lot of research, and deeply understanding the Uitronsystem.The author achieve the goal of video setting and video streaming.The project’s physical machine has been producted and more than100,000products are ordered. For more products information you can see theproduct web page as follow: http://www.foxda.com/detail.php?id=54. Theproduct has limitation for distance. Wifi can’t connect too longdistance.
