Abstract:
1. A method of processing broadcast data in a broadcast transmitter, the method comprising: randomizing enhanced data; encoding the randomized enhanced data at a first code rate; interleaving the encoded enhanced data; randomizing signaling data for signaling the enhanced data; encoding the randomized signaling data at a second code rate; interleaving the encoded signaling data; and transmitting the interleaved enhanced data and the interleaved signaling data through a data unit, wherein the data unit further includes known data, wherein the known data are categorized into a first pattern of known data and a second pattern of known data other than the first pattern of known data, and wherein at least one of the first pattern of known data and the second pattern of known data are used for channel estimation in a broadcast receiver.
