Abstract
Provided is a display system for transmitting FM signals to an external audio system having an FM reception function. The display system includes: a tuner for receiving an RF signal and dividing the RF signal into a video signal and an audio signal; an audio processor for receiving the audio signal from the tuner; an FM detector for searching usable channels or unused channels among FM frequency bands of a reception area and transmitting information on the unused channels; a microprocessor for setting at least one of the unused channels as an available channel, the unused channels being provided from the FM detector; a memory for storing the available channel under control of the microprocessor; and an FM transmitter for receiving the audio signal from the audio processor and transmitting the audio signal over at least one channel selected among the channels stored in the memory under control of the microprocessor.
