Abstract
A digital broadcasting receiver includes a RF switch to divide an entire channel range of an input broadcasting signal into at least two channel ranges for at least one of a received air broadcasting signal and a cable broadcasting signal, at least two channel searching parts to search each channel range distributed from the RF switch and to check channels in sequence from a lowest channel to a highest channel within the channel range to determine whether one of the digital broadcasting signal and the analog broadcasting signal is received, a memory to record information on a valid channel through which one of the digital broadcasting signal and the analog broadcasting signal is received in the entire channel range of the broadcasting signal, and a CPU to control the at least two channel searching parts in parallel to search each distributed channel range for the valid channel, and to determine the valid channel if the channel searching parts determine that a certain broadcasting signal is received, and to record the result into the memory, thereby, reducing the time taken to search a digital broadcasting channel and an analog broadcasting channel received through air and cable broadcasting signal.
