Embodiments of broadcasting receiver and methods for the same can operate two or more tuners or simultaneously display broadcasting signals of two or more channels. Embodiments of the invention can reduce system interference. A broadcasting receiver can include a plurality of tuners, and a controller for operating a tuner of a broadcasting signal not being displayed using an oscillation frequency that has reduced or avoids interference with another tuner of a currently selected and displayed broadcasting signal. For example, an interference controller can read stored PLL data with reference to a channel frequency of a currently selected and displayed broadcasting signal and write the read PLL data in other tuner(s) when only a broadcasting signal received by one of the tuners is currently selected and displayed.
