Abstract
An E8-VSB reception system, apparatus for generating data attribute and method thereof, and apparatus for channel encoding and method thereof are disclosed. In the present invention, E8-VSB data resulting from multiplexing a plurality of enhanced data encoded at different coding rates with main data is received. And, the main data and a plurality of the enhanced data are identified to be modulated from the received E8-VSB data. In particular, by generating M/E packet attribute information, enhanced packet attribute information, enhanced byte attribute information and E8-VSB symbol attribute information from the E8-VSB data attribute generating apparatus, the channel decoding apparatus can correctly identify to decode the main data, ½ enhanced data and ¼ enhanced data from one another.
