DVB-C数字接收机的软硬件设计和实现
摘要
数字电视系统取代模拟电视系统是必然的趋势。数字电视是21世纪最具发展前景的新兴产业,我国政府把数字电视列为新的经济增长点并大力推进数字电视系统的更新换代和普及工作。数字电视系统分为数字电视前端系统和后端接收机也即数字电视机顶盒。数字电视产业的发展是整个系统的大发展。在这个背景之下,本文对数字电视系统的前后端,尤其是后端数字电视接收机的相关技术和软硬件系统进行详细研究。
本文主要阐述了数字电视系统中相关理论和标准,数字电视前后端的关键设计,着重论述了数字电视接收机的软硬件设计与实现。文中首先简要介绍了数字电视在国内的发展现状和数字电视系统的发展趋势。然后简述了数字电视系统涉及到的理论和MPEG2传输流标准。接着阐述了数字电视接收机的软件系统,详细研究嵌入式实时操作系统STLite/OS20的关键技术。在作者实际工作的基础上,对硬件系统各部分和软硬件联调进行了深入讨论。文中将机顶盒硬件系统分为前端接口部分,音视频后处理部分和外围存储电路部分进行深入详细的阐述。最后结合实际工作,给出了软硬件联合调试的方法和技巧。
文中论述的数字电视机顶盒的设计和实现方法都是经过实践证实了的可行的方法,所开发的机顶盒己经应用于实际产品的生产。
It is the certain trend that the anolog television will be replaced by the digital television system. Digital TV has the best future in the 21st century. DTV is viewed as new and potential economy increasing by our government. The re-generation and dissemination of DTV have been carried on. DTV system is divided to two parts: DTV front part and DTV back-end part, the receiver of digital TV. The development of digital TV is that of the whole development of digital TV system. The thesis, under this background, studies the theory and related standards of the digital TV system in details, especially for the digital TV back-end part.
The thesis mainly discusses the theory and standards of Digital TV System. It introduces the design of Digital TV, both front and back-end, and studies the design and implementation of the DTV receiver in hardware and software. The thesis discusses the whole DTV resceiver system, firstly the present of development situation of the digital TV, then the future of Digital TV system as well as related theories and standards, thirdly the software of the resceiver and last the hardware system. The thesis briefly described the front tunner part, vedio and audio processing part, memory part and CPU part. Based on practical works and experience, thesis lists the methods and techniques of hardware and software co-debug. .
The feasibility of methods for designing and implementing the STB(Set Top Box) in the thesis has been proved in practice. The STB has put into practical mass-product.
