从理论和软件的角度讨论 Ｍ Ｐ Ｅ Ｇ２ 算法的论文已有很多，把算法作硬件实现的论述是文中的重点。在实际的硬件系统中会遇到实现上的各种问题，理论上的概念在实际的操作中有些是无法实现的。文中论述了采用硬件技术实现的一套实用化的数字电视编码和解码系统，较好地解决了系统的复杂性、可靠性和可实现性等方面的矛盾。从硬件开发的角度，对设计的调试方案作了较详细的描述。在仔细分析数字电视的系统结构的基础上，对于硬件实现中遇到的问题作了具体分析，并提出了解决的方法。在实际应用中取得了很好的效果。
From theory and software point of view to discuss M P E G 2 algorithm has many papers, the algorithm for hardware implementation is the focus of the article. In the actual hardware system will encounter a variety of problems on the realization of the concept of the theory in the actual operation of some can not be achieved. This paper discusses a set of practical digital TV encoding and decoding system using hardware technology to solve the contradiction between system complexity, reliability and realizable. From the perspective of hardware development, the design of the debugging program made a more detailed description. On the basis of careful analysis of the system structure of digital television, the problems encountered in the hardware implementation are analyzed in detail and the solutions are proposed. In practical application has achieved good results.
