Enhanced 8-VSB transmitting/receiving system, and data attribute generating apparatus and it's method

The present invention with each other and transmit to another code rate plurality of enhanced (Enhanced) multiplexing the data and after re-multiplexing the multiplexed enhanced data and the main data that is coded in, for generating a data attribute information to demultiplexer receives this It relates to the E8-VSB transmission / reception system. In particular, the present invention is the bit repetition and the interleaver memory for data attribute occurs just enhanced data for the next MAP at the time of an enhanced mode map change the next MAP in the current MAP is being input into an enhanced byte interleaver next MAP by initializing all data is in filled state, it is possible to change the MAP without a loss of enhanced data. In addition, by implementing the memory of the bit interleaver repeated and the structure of assigning the enhanced one bit per packet, while minimizing the amount of memory at the same time to shorten the initialization time of the memory. E8-VSB, the map change data attributes, interleaver
