    • The present invention relates to a PID/section filter which is adapted without any restriction to an ATSC standard or a DVB standard, comprising a processor module for detecting a PID and a TID by decoding the input transport stream, downloading the information requested by the viewer, and controlling the operation of the each system unit in order to store the information on a memory or ignores it, a PID comparing circuit module for comparing the PID value stored on an internal register with the PID value from the processor module, a download circuit module for downloading the extracted information among the decoded information by the processor module, and an external memory managing module for storing the information extracted in-accordance with the request of the viewer among the information decoded on the processor module.
    • 本发明涉及一种适用于对ATSC标准或DVB标准没有任何限制的PID /部分滤波器,包括用于通过解码输入传输流来检测PID和TID的处理器模块,下载由观看者请求的信息 并且控制每个系统单元的操作以将信息存储在存储器上或忽略它们; PID比较电路模块,用于将存储在内部寄存器上的PID值与来自处理器模块的PID值进行比较;下载电路 模块,用于通过处理器模块在解码的信息之间下载提取的信息;以及外部存储器管理模块,用于存储在处理器模块上解码的信息中根据观众的请求提取的信息。
