Abstract:
1. A system for remotely controlling a digital television (TV) using a remote controller, the system comprising: the remote controller configured to receive video and audio data input from the external storage medium, modulate the received data into a wireless signal, down-convert a local oscillation frequency of the modulated wireless signal, and transmit a first data stream included in the down-converted wireless signal to a TV body directly while transmitting a second data stream included in the down-converted wireless signal to an audio device directly, wherein the down-converted wireless signal is used to control the TV body or the audio device selectively, and wherein the first data stream comprises the video data without the audio data, and the second data stream comprises the audio data without the video data; a TV body configured to receive the down-converted wireless signal transmitted from the remote controller, demodulate the received wireless signal into the video data, and reproduce the demodulated video data, wherein the TV body does not demultiplex the audio data; and an audio device configured to receive the down-converted wireless signal transmitted from the remote controller, demodulate the received wireless signal into the audio data, and reproduce the demodulated audio data.
