DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA

摘要

A digital broadcast transmitting/receiving system and a method of processing data are disclosed. More specifically, the present invention performs and transmits additionally encoding process on at least one of the enhanced data and transmits the encoded enhanced data. Accordingly, the present invention may provide robustness to the enhanced data, thereby enabling the enhanced data to respond adequately and strongly against the fast and frequent change in channels. The present invention also generates a reliability map corresponding to the received enhanced data, and performs error correction decoding process on the received enhanced data based on the reliability information of the reliability map. Thereby the present invention may be enhanced the capability of the error correction on the received enhanced data. Accordingly, the present invention is even more effective in providing robustness when applied to mobile and portable receivers, which are also liable to a frequent change in channel and which require robustness against intense noise.
