Abstract
A method and apparatus for efficiently selecting a demodulation scheme for a particular channel in a digital broadcast receiver supporting a plurality of demodulation schemes are provided. The method includes receiving the digital broadcast signal of the channel; attempting demodulation of the digital broadcast signal using a demodulation scheme corresponding to a sequential index; and if the demodulation attempt succeeds, restoring data and if the demodulation attempt does not succeed, attempting demodulation again using a demodulation scheme corresponding to a next sequential index.
