The Design Of T-DMB Mobile TV Phone Player

Korea firstly released T-DMB standard about terrestrial wave and immediately put this standard into practice in Dec 2005.Many countries begin to focus on Mobile TV Phone and show extreme interesting.With the rapid increasing requirement of embedded devices,mobile TV phone will become a hot branch of the embedded devices development in the future.This article focuses on the principle of T-DMB standard,design of a T-DMB player and some key methods in T-DMB player development.Firstly,some global mobile TV phone standards will be introduced and a comparison between T-DMB and DVB-H will be made.In chapter 2,the principle of the DMB terminal receiver will be implemented, including the method of video-audio coding,scene description and the recovery of the system clock.Chapter 3 talks about structure of the DMB player,demultiplexing process of the TS stream,decoding BIFS scene,synchronization between video and audio,filter structure design of video and audio decoder and T-DMB player running information and effect will be implemented.In chapter 4,methods of the software modules transplanted on WinCE and Algorithm optimizing will be introduced.In the last chapter,the key technics will be summarized and the works in future will be put forward.
