Abstract

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.

Claims

Claims
[1] A method of processing data of a transmitting system, comprising the steps of:
receiving enhanced data through at least a plurality of paths, the enhanced data having information included therein;
grouping enhanced data bytes being inserted by each path so as to create a RS
frame, performing error correction encoding in RS frame units, and performing interleaving in super frame units, each super frame being configured of a plurality of RS frames;
receiving the interleaved RS frames through each path, thereby multiplexing and outputting the received RS frames in RS frame units; and performing encoding on the enhanced data at a coding rate of G/H, the enhanced data being multiplexed and outputted, wherein G<H.
