Patent ID: 8254706

Claim:
A broadcasting transmitter comprising: a randomizer for randomizing enhanced data; a first Reed Solomon (RS) encoder for first RS encoding the randomized enhanced data; a convolutional encoder for convolutional encoding the first RS-encoded enhanced data in symbol units; a symbol-to-byte converter for converting the convolutional-encoded enhanced data into byte units; a deinterleaver for deinterleaving the enhanced data converted into byte units; a second RS encoder for second RS encoding the deinterleaved enhanced data; an interleaver for interleaving the second RS-encoded enhanced data; a trellis encoder for trellis encoding the interleaved enhanced data; a first multiplexer for multiplexing the trellis-encoded enhanced data with segment synchronization data and field synchronization data; a pilot inserter for inserting pilot data into the multiplexed data; and a modulator for modulating a broadcast signal including the pilot-inserted data with a Vestigial Sideband (VSB) modulation scheme.
