The Design Of Wireless Digital TV Based On DMB-TH Standard

Digital TV has been developing for more than 20 years.China starts its Digital TV scheme on early 90s of 20 century.Digital TV will replace analog TV in next several years.People can watch programs more than 4 times as before.As a result,people can get more information and enjoy themselves more.During this Transition stage,STB(Set Top Box)holds the balance.STB is not only a substitute of digital TV,it is also the creation of new developing of digital TV such as the developing of VOD(Video On Dcvice)and CA(Conditional Access)and IPTV.It is useful to study on the design of STB since the analog-digital hybrid.DTV is not come into being.Meanwhile it studies on STB can accelerate the development of multimedia.This dissertation involves in the development of STB in two parts:application software design and hardware design. Work is finished bases on the chip of Hi2011.The main contents are as follows:1.Discussions of the key techniques of STB such as the operating system are included.Analysis of the hardware architecture of STB and the chip of Hi201 1e that we plan to use are also included in this dissertation.2.The design of program searching and parsing and demux module,which are the Application software of the STB,are discussed in this dissertation.3.The hardware design of STB is discussed and the PCB(Printed Circuit Board) picture is presented.4.We finished software debugging and program parsing;the result is presented at the last chapter of the dissertation.
