Abstract
A microphone/speaker-contained wireless remote control system for an Internet device, comprising a system body and a remote controller, each of which includes a circuitry for performing a voice compression operation and modulating an analog audio signal into a digital signal. The remote controller further includes a speaker for transferring an audio signal from the Internet device to the user, and a microphone for receiving a user's voice. In the case where a singing room function is selected, the user's voice received by the microphone is processed in a digital manner. Radio frequency signals are transmitted and received between the remote controller and Internet device through antennas.
