Abstract
Official abstract text for this publication.
A digital television (DTV) transmitter and a method of coding data in the DTV transmitter method are disclosed. A pre-processor pre-processes the enhanced data by coding the enhanced data for forward error correction (FEC) and expanding the FEC-coded enhanced data. A data formatter generates one or more groups of enhanced data packets, each enhanced data packet including the pre-processed enhanced data. And, a packet multiplexer generates at least one burst of enhanced data by multiplexing the one or more groups of enhanced data packets. Herein, each burst of enhanced data includes at least one group of enhanced data packets. The DTV transmitter may further include a scheduler which generates first and second control signals to control operations of the data formatter and the packet multiplexer, respectively.
First claim
Opening claim text (preview).
What is claimed is: 1. A digital television (DTV) transmitter comprising: an encoder for encoding enhanced data at a code rate of 1/N, wherein N is an integer greater than 1; a deinterleaver for deinterleaving the encoded enhanced data; a Reed-Solomon (RS) encoder for RS encoding the deinterleaved enhanced data to add first parity data to the deinterleaved enhanced data; an interleaver for interleaving the enhanced data to which the first parity data are added, wherein the i…
