  • Publication number: 20130300702
    Abstract: A method of displaying information in a mobile terminal having a touch screen is provided. The method includes determining whether a touch input is generated by a touch screen, determining whether the touch area moves, calculating a movement direction of the touch area by extracting a value of the touch area movement, determining a current mode according to the calculated movement direction of the touch area, executing a function of the current mode corresponding to the extracted value of the touch area movement, and displaying, while executing the function of the current mode, at least one of a displacement value generated by executing the function of the current mode and a current mode icon indicating the current mode. Accordingly, when displaying information according to a touch input, changes of information may be displayed distinctively, and thereby user convenience may be improved.

  • Patent number: 7567784
    Abstract: A tuner, a broadcast signal processing apparatus and method, which satisfy reception sensitivity of both terrestrial and cable televisions, when selecting a broadcast signal through a single conversion tuner, are provided. A tuner selects a broadcast signal of a selected channel. The tuner includes an input filter that filters a received broadcast signal into plural frequency bands based on a predetermined frequency band. An amplifier amplifies a second signal having an original phase induced by an output signal of the respective frequency bands, and a first signal having an opposite phase of the second signal, and outputs the signal induced by the amplified first and second signals as an amplification signal of the signal in the respective frequency bands. An inter-stage filter filters a frequency of the broadcast signal corresponding to the selected channel among the amplification signals output from the amplifier.
