DIGITAL TELEVISION TRANSMITTING/RECEIVER AND METHOD OF PROCESSING DATA IN DIGITAL TELEVISION TRANSMITTER/RECEIVER

摘要

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.

主权项

1. A method of transmitting broadcast data to a receiver, the method comprising:
performing first error correction encoding on first enhanced data; performing first interleaving on the first error correction encoded enhanced data; performing second error correction encoding on second enhanced data; performing second interleaving on the second error correction encoded enhanced data; and transmitting a first data unit including the first interleaved enhanced data, a second data unit including the second interleaved enhanced data and parameters through a frame unit, wherein the parameters provides the receiver with information for signaling the data units within the frame unit.
