The Design And Realization Of Car Digital Television Based On ITRON System

With the rapid development of the science and technology,Car Digital Television has become a well-established industry.However,with the rapid innovation of new products of Car Digital Television,various problems have emerged.When the Car Digital Television received the weak signal,the screen will be not smooth or be dark and will have adverse effects on customer experience.The customer will have to reselect channel,which may endangers security of driving.Thus,it might provide strong support to improve the Car Digital operator's core competitiveness by solving the problems of the existing system and providing Car perfect Digital Television system.In this thesis,we had thought over the actual needs of the Car Digital Television system provided by a Car Digital operator and we use the stable forming ITRON system in the software development.We take the Car Digital Television technology as the core to solve the problem of being Adverse effects in the when the channel signal becoming weak in the driving car.Because of The system increased background control,the background can start Relay station search,when the foreground signal become weak.Also the system can switch to the same channel and become the Optimal Channel selection,when retrieve the channel with the strong signal.At the same time,the switching does not affect to the foreground seeing and hearing and saves time with the auto switching strategy.Therefore,the system create the perfect customer experience of the real-time smooth playback.The program has passed a number of substantive tests and has been initially applied in practice and has got a better application effect which provided an effective solution to the practical problems of the Car Digital Television.
