摘要：
A method and system for speeding up channel change in an Internet protocol television (IPTV) service and digital broadcast service are provided. The system includes an extractor extracting a program association table (PAT) and a program map table (PMT), which include information for identifying elementary streams (ES) of a channel in a motion picture experts group-transport stream (MPEG-TS), and an output unit identifying elementary streams for the user-requested channel, in a MPEG-TS based on the PAT and the PMT transmitted from the extractor until the PAT and PMT in the received MPEG-TS are available, and outputting the decoded video and/or audio.
