DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA

摘要

The present invention relates to a digital broadcasting system. More particularly, the present invention inserts and outputs pre-defined known data, which are already known by a transmitting system and a receiving system, in a specific place within a data area to which enhanced data are transmitted, and wherein the receiving system detects the known data for a demodulating or equalizing process, such as frequency synchronization, thereby enhancing a receiving performance in an environment with frequent channel changes and vulnerable to noise.
