Embodiment Construction

[0043] Certain exemplary embodiments will now be described in more detail with reference to the accompanying drawings.

[0044] Figure 1A A television (TV) 100 including a built-in FM transmitter is shown according to an exemplary embodiment.

[0045] refer to Figure 1A , the TV 100 may include an image input unit 110 , a broadcast receiving unit 120 , an AV processing unit 130 , a video output unit 140 , an audio output unit 150 , an FM transmission unit 160 , a storage unit 170 , an operation unit 180 and a control unit 190 . The FM transmitter may mean a device including the FM transmitting unit 160 and the control unit 190 and transmitting an audio signal as an FM band signal.

[0046] The image input unit 110 may receive an image signal from an external source. That is, the image input unit 110 may function as an interface for receiving an analog image signal or a digital image signal from the outside of the TV 100 . The interface may be an AV interface such as s-vide...

Abstract

A frequency modulation (FM) transmitter, a broadcast receiver having the same, and a method of transmitting an audio are provided. The FM transmitter selects a specific frequency from among frequencies in FM frequency band, which exclude a frequency in use, and transmits an audio signal over the selected specific frequency. Accordingly, the FM transmitter can transmit the audio signal using the confusion-free or interference-free frequency. As a result, a user can select a frequency to transmit the audio of the broadcast receiver easily.

Description

[0001] priority [0002] This application claims priority to Korean Patent Application No. 10-2010-0046452 filed with the Korean Intellectual Property Office on May 18, 2010, the contents of which are incorporated herein by reference. technical field [0003] Apparatuses and methods consistent with the description herein relate to a Frequency Modulation (FM) transmitter, broadcast receiver, and method for transmitting audio, and more particularly, to an audio signal of an input image as an FM band An FM transmitter for signal transmission, a broadcast receiver having the FM transmitter, and a method for transmitting audio. Background technique [0004] TV was once the sole or primary provider of picture and sound in the home. But due to the rapid development of image technology, current viewers have various AV devices so that they can use them in desired combinations. For example, a viewer can create a home theater environment where the TV provides only the video screen, w...
