Abstract
A digital broadcasting system and a data processing method are disclosed. Herein, additional encoding is performed on mobile service data, which are then transmitted, thereby providing robustness in the processed mobile service data, so that the mobile service data can respond more strongly against fast and frequent channel changes. The transmitting system includes a first encoding module grouping a plurality of inputted mobile service data bytes so as to form a RS frame and performing error correction encoding in RS frame units, a second encoding module encoding the primarily encoded and outputted data at a coding rate of G/H, wherein G is smaller than H (i.e., G<H), and a third encoding module performing trellis encoding on the secondarily encoded and outputted data.
