PURPOSE: A transmission device of a digital broadcasting system having a complex ECC(Error Correction Coding) function is provided to differently perform ECC processes for data transmitted through an HP(High Priority) layer and data transmitted through an LP(Low Priority) layer in consideration of communication environments, thereby improving transmission efficiency of a system. CONSTITUTION: The first and second RS encoders(112,122) encode the first and second TSs(Transport Streams) to enable ECC functions, respectively. The first and second outer interleavers(114,124) re-array data encoded in the first and second RS encoders(112,122), respectively. A convolution encoder(116) convolution-encodes the data re-arrayed in the first outer interleaver(114). A turbo encoder(126) encodes the data re-arrayed in the second outer interleaver(124) to enable an ECC function. An inner interleaver(128) re-arrays the data encoded in the convolution encoder(116) and the data encoded in the turbo encoder(126), respectively. A modulator portion(140) digitally modulates the re-arrayed data, and transmits the modulated data. |
