The Study On Encapsulation And Integration Of The Media In MMS System

This paper introduces the system of MMS and detailedly researches on the architecture of MMS.The implementation of MMS system in the terminal includes several parts:MMS editor,MMS PDU module,communication module and media module.The relationship of these modules and the implementation of these module have been given in this paper,include the flow of the editing and playing MMS.The design of the user interface in the MMS editor module,the architecture and function of each MMS PDU,the interface and method of playing media and so on.This paper discusses the encapsulation and integration of audio and video in detail,especially the encapsulation and realization of MPEG-4 and H.264.In the realization of the timed text,the analysis of the timed text conformance is also given.At the last,the algorithm of JPEG is discussed as the realization of JPEG which is fit for MMS.
