Patent ID: 8005304

Claim:
A broadcasting transmitter comprising: a randomizer for randomizing enhanced data; a first Reed Solomon (RS) encoder for generating first RS-encoded enhanced data by first RS encoding the enhanced data; a convolutional encoder for generating convolutional-encoded enhanced data symbols by convolutional encoding the first RS-encoded enhanced data and outputting the convolutional-encoded enhanced data symbols; a symbol-to-byte converter for generating converted enhanced data by converting the convolutional-encoded enhanced data symbols into byte units; a deinterleaver for generating deinterleaved enhanced data by deinterleaving the converted enhanced data in byte units; a second RS encoder for generating second RS-encoded enhanced data by second RS encoding the deinterleaved enhanced data; an interleaver for generating interleaved enhanced data by interleaving the second RS-encoded enhanced data; a trellis encoder for generating trellis-encoded enhanced data by trellis-encoding the interleaved enhanced data; and a first multiplexer for multiplexing the trellis-encoded enhanced data with segment synchronization data and field synchronization data.
