摘　　要：从实用的角度出发,针对MPEG-2复用器输入传输流的节目特殊信息表可能有一个或多个分段,以及一个分段可能有一个或多个传输流包的情况进行详细的探讨,并提出节目特殊信息分析提取的FPGA实现方案。最后通过实际码流的测试,证明该方案的可行性。A scheme is put forward from a practical point of view, which is implemented by FPGA to extract and analyze PSI information in transport streams according to MPEG - 2 multiplexer,after a detailed discussion on the fact that one PSI table may have one or more sections,as well as a section may have one or more TS packets in a transport stream. The feasibility of the scheme is demonstrated by the actual transport stream.
