Abstract
A digital broadcast protocol conversion system including: a PSIP/PSI extractor for demultiplexing a transport stream of an ATSC broadcast standard to extract PSIP/PSI data; an SI/PSI extractor for demultiplexing a transport stream of a DVB broadcast standard to extract SI/PSI data; a protocol converter for converting the PSIP/PSI data to SI′/PSI′ data corresponding to a broadcast protocol of the DVB broadcast standard or converting the SI/PSI data to PSIP′/PSI′ data corresponding to a broadcast protocol of the ATSC broadcast standard; and a multiplexer for multiplexing the SI′/PSI′ data and the transport stream having the PSIP/PSI data extracted therefrom, or multiplexing the PSIP′/PSI′ data and the transport stream having the PSIP/PSI data extracted therefrom, thereby converting the broadcast protocol between different broadcast standards.
