多通道实时MPEG编解码器的方案设计及实现
摘要
数字化是电视产业发展的热点。随着年内各项国家相关标准的制定,数字电视技术正广泛的应用在各行业中。在市场需求和技术发展的促进下,功能多样的数字电视产品正在逐步走入寻常百姓家。电视制作和播出正在急切地由模拟向数字化过渡,传统的电视制作播出设备正在发生深刻的变革。
本文首先回顾了数字电视广播的发展历史,并对数字电视前端系统的组成进行了分析。根据电视系统数字化的要求,引出了多通道实时MPEG-2/4编解码器系统的设计需求。在对视频压缩标准和DVB标准进行了简要介绍后,提出了四种设计方案进行比较,并选择了其中最符合系统要求而稳定性最好的方案进行实现。接着,对实时MPEG-2/4编解码器的硬件系统和软件系统分别进行了论述。着重讨论了软件系统中硬件配置模块、数据库操作模块和硬件驱动模块的设计,及其与主控模块的协同关系,强调了系统软硬件中的自检测和自恢复设计。
在文章最后,作者以本文所论述系统为基础,介绍了可由本系统设计方案衍生出的三种派生产品,为数字电视前端系统的发展提供了更强有力的支持。
At present, digital TV become the hotpot of the television industry. In those years, with the establishment of relevant Chinese standards, the technology of digital TV has been applied in many other fields. Expedited by the market demand and the development of technology, more and more digital TV products will be found in common family. At present, TV program execution and broadcast are in the transition status. The equipment used in this industry is innovating profoundly.
This thesis first reviews the development history of Digital TV Broadcasting, and analyses the structure of the TV station forepart. Then, based on the requirement of Digital TV, this thesis put forward the demands of Multi-Channel Real-time MPEG-2/4 encoder-decoder system. After analyzing relative standards of digital TV system, this thesis put forward four designs of the encoder/decoder system and compares them to get the best design which accord with the demands. Furthermore, it discusses the hardware design and software design of this encoder system, emphasizes the design of hardware configuration module, database configuration module, and driver module, and the cooperation of these modules and main controller module. This thesis also stresses the self-test and self-recovery design of system.
At the end, three equipments can be derived from the encoder/decoder system are brought forward, to make the digital broadcast front-end system more consummate.
