Design And Implementation Of Mobile Terminal Video Player Based On SP Platform

Along with mobile communication and multimedia technology fast development,the embedded multimedia function of mobile terminal is stronger. The SP mobile phone developing platform is the only native platform which provides the entire mobile phone developing plan support to the customer. This platform with single chip plan solution support mobile terminal to realize the strong multimedia function while shortening the research and development cycle of the products, reducing the production cost.This article takes the SP mobile phone developing platform as a foundation. First briefly introduces mobile communication technology development course as well as the characteristics of the 4th generation mobile communication system , Discusses embedded system's composition and the embedded operating system's technical characteristics,introduces the SP mobile phone developing platform's development environment in detail and makes a detailed demand analysis to video player based on the SP platform. Demand analysis includes the demand modeling and the formulation instructions of software specification. After the demand analysis, this article gives a detailed software design and implementation of video player. Based on the SP developing platform's feature, I divide the video player's development into two layers to carry on the design and implementation. One layer is the window design, mainly defines the window attributes and the connected window processing function; Another layer is function realization, mainly unifies the resources which the SP mobile phone platform provided and function analysis to the vedio player to realize the demand definition function. Finally it carries on the function test.
