Karaoke device capable of wirelessly transmitting video and audio signals to a television set

DETAILED DESCRIPTION Therefore, the objective of the present invention is to provide a karaoke device which is capable of wirelessly transmitting video and audio signals to a television set.
According to the present invention, a karaoke device is capable of wirelessly transmitting video and audio signals to a television set and includes a song memory unit for storing digital audio data and lyrics data therein.
A processing unit is connected electrically to the song memory unit and is operable to retrieve the digital audio data and the lyrics data from the song memory unit.
An audio synthesizer unit is connected electrically to the processing unit for receiving the digital audio data and for generating a stereophonic digital audio output corresponding to the digital audio data.
A digital-to-analog converting unit includes a digital-to-analog converter which is connected electrically to the synthesizer unit and which receives and converts the digital audio output into an analog audio signal, and a mixer which is connected electrically to the converter so as to receive the analog audio signal and which is adapted to be connected electrically to an external microphone unit so as to receive an external voice signal therefrom.
The mixer mixes the analog audio signal and the external voice signal and generates a mixed audio signal output.
An audio-visual signal transmitting unit includes an image memory unit for storing predetermined digital video data and character data therein.
A control means is connected electrically to the processing unit and the image memory unit for the receiving the lyrics data from the processing unit and the digital video data from the image memory unit.
The control means is operable to convert the digital video data to an analog video signal and to generate characters based on the character data and corresponding to the lyrics data.
The characters are superimposed on the analog video signal.
A modulator is connected electrically to the control means and the converting unit so as to receive the video signal from the control means and the audio signal output from the converting unit and so as to generate a modulated video signal and a modulated audio output
