METHOD OF PROCESSING DVB-T2/S2/C2 PIPING-FORMAT BROADCASTING SIGNALS WITH MEMORY SHARING, AND COMPUTER-READABLE RECORDING MEDIUM WITH BROADCASTING SIGNAL PROCESSING PROGRAM FOR THE SAME

摘要

PURPOSE: A method for processing a DVB-T2/S2/C2 piping format broadcasting signal based on memory sharing and an electronically decodable recording medium including a piping format broadcasting signal processing program therefor are provided to efficiently process data by dividing a file mode and an Ethernet mode through a preprocessing step and modeling a broadcasting stream. CONSTITUTION: A DVB-T2 receiver identifies a stream transmission mode as an NM mode or a HEM mode b parsing a header of a baseband frame(S280). The DVB-T2 receiver extracts actual content data for a gathered MPEG2(Moving Picture Experts Group2)-TS(Transport Stream) packet stream according to the identified stream transmission mode(S290-S320). The DVB-T2 receiver stores the extracted actual content data a share memory. The DVB-T2 receiver implements a broadcasting program by decoding an MPEG2-TS of the actual content data on the share memory(S330-S360).
