Abstract

Official abstract text for this publication.

A method of processing a digital television (DTV) signal is disclosed. Herein, the DTV signal is generated by performing Reed-Solomon (RS) encoding on additional data, multiplexing the RS-encoded additional data with main data, RS encoding the multiplexed additional and main data, interleaving the RS-encoded additional and main data, trellis encoding the interleaved additional and main data, and transmitting a Radio Frequency (RF) DTV signal including the trellis-encoded additional and main data. The method to process the DTV signal includes receiving the DTV signal including the additional data multiplexed with the main data through an antenna, in which signaling information is periodically inserted in the additional data. The received DTV signal is demodulated including performing channel equalization on the demodulated DTV signal. Trellis decoding is performed on the channel-equalized DTV signal. Further, the additional data from the trellis-decoded DTV signal is extracted including removing dummy data from the extracted additional data.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of processing broadcast data in a broadcast transmitter, the method comprising: encoding first enhanced data being input through a first path at a first code rate; encoding second enhanced data being input through a second path at a second code rate; first interleaving the encoded first enhanced data; first interleaving the encoded second enhanced data; converting the first-interleaved first enhanced data into symbol units; converting the…
