摘要
本文在对DVB OC标准理论研究的基础上,提出了一种对象轮播专用码流分析软件的设计实现方法。该方法采用层次递近的方式,解析码流中传输的对象,并根据获得的对象类型进行下一层次的解析,直到解析完全部对象,从而获得码流中全部对象的内容和逻辑关系。最后采用VC6.0编写程序证实了这种方法的可行性。通过此软件,可以将对象轮播中复杂的数据结构以图形的方式形象地表示出来,便于更好地对基于对象轮播的数据广播码流进行分析和研究。
Based on the research of DVB O12 standard, this paper introduced a method of designing object carousel special stream analyze software. This method is that the bit stream is parsed progressively, and it＇s parsed on next level according to the result in the previous level. After all the objects transmitted are parsed, the content and logical relationships are obtained. The feasibility is proved by programming using VC6. 0 Using this software, it can show the complex data structure in Object Carousel stream in the form of graphics, and will be convenient for researching and receiving the Obiect Carousel data.
