DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA

摘要

A digital broadcast system is disclosed. In order to group a plurality of enhanced data packets having information, multiplex the group with main data, and transmit them, the system and method stratify the group to form a plurality of regions, and classify types of inserted data, and processing methods, etc., according to characteristics of stratified regions. Especially, the present invention performs pre-process differently according to types of data inserted to the stratified regions in the group and types of inputted enhanced data, receiving performance of a receiving system can be enhanced even in an environment where channel variation is significant and noise is serious.
