Image processing system and control method thereof
First Claim
1. An image processing system which communicates with an external image source device, the image processing system comprising:
- a display device which receives a modulated remote control signal modulated by a modulation method, demodulates the modulated remote control signal to generate a demodulated remote control signal and transmits the demodulated remote control signal; and
a relay device which receives the demodulated remote control signal from the display device and modulates the demodulated remote control signal according to the modulation method to generate an output remote control signal, and outputs the output remote control signal to the external image source device,wherein the relay device is independent from the display device.
