- Provided are a data server, which is added to a digital broadcast emitting system to emit data broadcasting based on the Programming Metadata Communication Protocol (PMCP), a conventional international specification defined to secure inter-operability between devices of a digital broadcast emitting system; a metadata structure for securing inter-operability between devices of the conventional digital broadcast emitting system; a data stream generating device using the metadata structure; and a digital data broadcast emitting system and method thereof. The PMCP extended metadata of the present invention are formed to include channel type metadata which provide system information of a data event constituting a data broadcast program; and Program and System Information Protocol (PSIP) data event metadata which provide identification information, program guide, and encapsulation information of a data event.
