MPTS-SPTS SEPARATOR

摘要

PPROBLEM TO BE SOLVED: To provide an MPTS-SPTS separator in a digital broadcasting system which can eliminate the waste of an unnecessary bandwidth and can separate SPTS from MPTS in a small scale SO (System Operator) and an ONU (Optical Network Unit). PSOLUTION: A receiving interface 110 includes an MPTS-SPTS separator 100 and a transmitting interface 140. The separator 100 detects a PAT packet from MPEG-2 MPTS data provided from a digital broadcasting program provider, analyzes a PID (Program ID) of PMT corresponding to a plurality of programs existing within an MPEG-2 MPTS packet, receives single program information selected by a user, removes a packet concerning all of the programs except the selected program, changes the PAT by leaving only the PID of the PMT concerning the selected program and deleting the PID concerning the other programs, and inserts the PAT into a stream corresponding to the selected single program.
