Digital video broadcasting terrestrial receivers include a fast Fourier transformer that is configured to generate a frequency domain signal from a demodulated DVB-T signal using a range of a window, and an equalizer that is configured to equalize the frequency domain signal according to a channel selection to generate an equalized frequency domain signal. Preferably, the method also includes selectively precluding a user from viewing a second screen subsequent a first screen until data is entered into said first screen. The control panel includes light reflecting, light refracting, light filtering, andor light absorbing components to enhance the intensity of the light emitted by the light-emitting indicators relative to ambient light incident thereon.
