The Design And Implemetation Of Intelligent Multimedia System Based On TMS320DM365 Platform

With the maturing of 3G technology and the coming of the era of IOT (Internet of Things), intelligent, embedded multimedia applications have got more and more favour of people in recent years, and there is a wide range of applications in many areas, such as security monitoring, TV set-top boxes, family multimedia servers, digital TV, video phone, video conference, personal media players, electronic imaging and so on. According to actual demands, we design and implement a intelligent multimedia system based on TMS320DM365 platform, and this system has a variety of functions of multimedia embedded applications, and has a good user interface.This thesis firstly describes the research status of intelligent multimedia system, and introduces the main characteristics of DaVinci technology and the development situations of DaVinci technology platform. Based on this, this thesis has expounded the hardware structure of DaVinci platform TMS320DM365 and the related knowledge background of software development on DaVinci platform.Then, according to the application requirements of intelligent multimedia system, this thesis designs and implements the application framework of the system, and describes the functions of various software modules in the whole system. After describing the overall framework, several key software modules of the system are analyzed in details, they are video acquisition module supporting SD (Standard Definition) and HD (High Definition) video signals, motion detection module to give alarms when object invasion is found, audio and video synchronization mechanism in the course of multimedia processing, and web-based remote control module.For multimedia playback demand, this thesis transplants and implements a multimedia playback subsystem based on GStreamer software framework. First introduces the basic knowledge of GStreamer software framework, including writting the application programming code and composing the pipeline plugin based on GStreamer. Then develops the plugin of TMS320DM365 platform and designs a fully functional multimedia player which is able to play AVI format files. Finally the whole system is tested and summarized, and this thesis discusses the urgent needs to perfect and improve the related aspects.
