摘要
PSI／SI信息是数字电视实现DⅧ业务的数据基础。该文简述了PSI／SI信息及SI模块与其它模块的关系，从逻辑上将sI模块需求分解为不同的软件模块，并定义了每个模块的数据和功能，以及模块间的交互，最后介绍了sI模块对各种表信息提取和解析的实现算法。
PSI/SI is the data basis for realizing the DVB business in DTV. This paper introduces the PSI/SI information and the relationship between SI module and other modules.SI module is decomposed into different software mdodules in logic and defines the function and data of each modules.Then it describes how to fulfill the extraction and analysis of all kinds tables and gives conclusion.
