Patent ID: 8014459

Claim:
A digital broadcast transmitter, comprising: a byte-bit converter configured for converting enhanced data bytes into bit units and outputting enhanced data bits; an encoder configured for encoding the enhanced data bits at a code rate of 1/H, wherein H is an integer greater than 1; a deinterleaver configured for deinterleaving enhanced data corresponding to the encoded enhanced data bits; a Reed-Solomon (RS) encoder configured for RS encoding the deinterleaved enhanced data by adding parity data to the deinterleaved enhanced data; and an interleaver configured for interleaving the RS-encoded deinterleaved enhanced data, wherein an output of the interleaver includes a first data group including rows having a length of 207 bytes, wherein an i th row in the first data group has N consecutive MPEG header bytes, wherein an input of the interleaver includes a second data group including rows having a length of 207 bytes, wherein a j th row in the second data group has M consecutive MPEG header bytes, and wherein N>M and i, j, M and N are integers greater than 1.
