Receiver For Digital Television Terrestrial Broadcasting Based On DMB-TH

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 Transion stage,receiver holds the balance.Receiver is not only a substitute of digital TV,it is also the creation of new developing of digital TV such as the developding of VOD(Video On Device)and CA(Conditional Access)and IPTV.It is useful to study on the design of receiver since the analog-digital hybrid.DTV is not come into being.Meanwhile it studies on receiver can accelerate the development of multimedia.This dissertation involves in the development of receiver in two parts:application software design and hardward design.Work is finished bases on the chip of Hi2016. System requirement of receiver functions is analyzed,and the hardware system frame is worked out.The paper put forward the Hi2016's solution project,has improved the system's integration and function expansion.Furthemrore,the main chips of receiver's hardware system are introduced in this paper,and the paper not only provides detailed introductions for each module but also display some circuit designs.The powe-supply structure of hardware system and power adapter's design are studied as well.Receiver is based on uC/OS-Ⅱoperation-system.Some important characters of uC/OS-Ⅱare studied including running condition,replantation measure.The paper analyses the system's software structure,and focuses on the driver design of de-modularization chip and I2C's bus.
