Patent ID: 8836868

Claim:
An information processing apparatus comprising: a tuner that receives a wireless digital video broadcast (DVB) signal; a power supply that converts an input direct current (DC) power supply into a predetermined voltage by switching the input DC power supply at a switching frequency to generate a driving power supply; a touch-panel display that displays video corresponding to the DVB signal received by the tuner, wherein the driving power supply generated by the power supply powers the touch-panel display; and a controller that determines a frequency channel of the DVB signal received by the tuner and controls the switching frequency to avoid interference between the driving power supply and the DVB signal received by the tuner by controlling the switching frequency to be 24 MHz when the determined frequency channel of the DVB signal is a first frequency, and controlling the switching frequency to be 12 MHz or 6 MHz when the determined frequency channel of the broadcast television signal is a second frequency, which is less than the first frequency.
