The Design And Implementation Of The Vehicle Mobile Of Terrestrial Broadcasting Digital TV

Since 1990s, the technology in television has evolved into digital era. The trends of studying on digital TV(DTV) module, setting DTV standards, developing DTV equipment and DTV industrialization have become more and more popular in the world. In August 2006, China launched its own Digital Television Terrestrial Broadcasting Standard.The author first conducted a detailed introduction on the research situations and standards of DTV both at home and abroad, then analyzed in comparison and summed up the strength and weakness of various standards. Based on the current situation of domestic technology and industry levels, the author make a research on the realization of the receiving terminal of the terrestrial digital TV broadcasting. The author provided software and hardware solutions on vehicle mobile receiver and implemented the vehicle mobile reception of terrestrial digital TV broadcasting. The vehicle mobile receive transmitting standard adopts Tsinghua's DMB-TH terrestrial transmission standard which has become the major component of China's Digital Television Terrestrial Standard.Compared with the currently available vehicle mobile receiver solutions, this solution is based on China's Digital Television Terrestrial Standard. This solution also has a very high capability/price ratio because it is suitable for receiving digital TV broadcasting signals in standard definition and has broad market prospect and application values. To launch a terrestrial digital TV transmission terminal based on domestic technology is no doubt with a positive significance.
