SECTION FILTERING METHOD, PARTICULARLY CONCERNED WITH IMPROVING A PROCESSING SPEED OF SECTION FILTERING BY RANDOMLY CONNECTING A PID FILTER WITH A SECTION FILTER

摘要

Purpose: a kind of section filter method, which is provided to, arbitrarily has a section filter for PID (packet ID) filter, in order to limit the section filter that should pass through by these by PSI (program specific information) Pass of PID filters, to minimize the processing time of section filter. Construction: a PID index storages are additionally configured to the PID filter index values being stored in a section filter. If PID filter passes, in self index value and by the part of PSI data to section filter, section filter receives the part with the PSI data of a PID filter index, a section filter process is executed. A PID filter index is searched for the equivalent section filter of pass PID filter index, only inputs the part of PSI data to a section filter, PID filter index having the same.
