The Development Of The Dtv Receiver Chipsets

The technology of communications and information in the world will lead to therapid development of the entire broadcasting industry chain ransformation, digitalTV is a key step in this transformation. Along with the overall digital TV andbroadcasting, the traditional TV media will be inosculate in technology, featuresgradually and information, communication, other means of mutual integration ofthe field,and that to form a new, large digital TV industry. A new network of digitalTV and broadcasting could provide some service,for extempore mutual highdefinition TV,medicine care,education etc. The development of digital TV will beanother major technological revolution in the history. Digital TV broadcasting canbe divided into satellite digital television broadcasting, cable digital televisionroadcasting and terrestrial digital TV broadcasting three kinds. After years ofrelentless research and development in China in the technical aspects of digital TVterrestrial broadcasting made a lot of results, with the core intellectual property andhas formed a national standard in the next decade will be have great commercialvalue and development. Digital TV is not only a standard, equipment and programproduction and many other parts of the source of mutual support and matchingtechnology systems, but will also have an impact on related industries and topromote its development. Therefore, as the whole digital TV industry chain, animportant part of the receiver-chip module design and R & D by industry-wideconcern, especially Tuner-SiP chip system integration solutions, with its low cost,low power consumption and the characteristics of small size, the market prospectsare generally good.In this paper, we are succeed to receive and play back of the mobile digital TVbase on CMMB standard.Now that at the time of the mobile digital TV being in theascendant,the project is innovation and in advance.What I do in this project is thathow to use an existing industrial platforms, SiP technology includes dual-tuner anddemodulator features a variety of low-cost single-chip design, expand the researchand discussion to find an optimal solution.
