DEVICE FOR HEARING PIP AUDIO DATA OF DIGITAL TV

摘要

PURPOSE: A device for hearing PIP audio data of a digital TV is provided to allow a digital TV user to hear sub-picture audio data using a bluetooth module included in the digital TV when the user watches a main picture and a sub-picture simultaneously. CONSTITUTION: A device for hearing PIP audio data of a digital TV that receives at least one broadcasting signal includes a main channel processor, a sub channel processor, and a headset. The main channel processor processes audio and video signals inputted through the first channel to output the processed signals. The sub channel processor processes an audio signal inputted through the second channel to output the processed signal to a bluetooth module(20). The headset radio-modulates the audio signal output from the sub channel processor into an RF signal and receives the RF signal.
