Abstract:
1. A broadcasting transmitter for processing a digital television (DTV) broadcasting signal, the broadcasting transmitter comprising: a randomizer for randomizing enhanced data; a convolutional encoder for convolutional encoding the randomized enhanced data: a deinterleaver for deinterleaving the convolutional encoded enhanced data and known data; a Reed-Solomon (RS) encoder for RS-encoding the deinterleaved data; an interleaver for interleaving the RS-encoded data, wherein the interleaved data further include main data, and wherein a convolution encoding process was not performed on the main data; and a trellis encoder, having at least one memory, for trellis-encoding the interleaved data, wherein the trellis encoder initializes the at least one memory at a position where the known data starts.
