PMCP EXTENSION METADATA, DATA STREAM GENERATING DEVICE, DIGITAL DATA BROADCASTING EMISSION SYSTEM AND DIGITAL DATA BROADCASTING EMISSION METHOD THEREOF

摘要

Provided are a PMCP extended metadata for securing interoperability among devices constituting a digital data broadcasting emitting system, a data stream generating device using the same, a digital data broadcasting emitting system and a digital data broadcasting emitting method. The PMCP extended metadata includes: a channel metadata for providing system information of data events constituting a data broadcasting program; a program and system information protocol (PSIP) data event metadata for providing identification information and program guide of data events; and an advanced television system committee (ACAP) data service metadata for providing encoding information including signaling information and transmission protocol information of data broadcasting contents corresponding to data events.
