    摘要： A karaoke apparatus includes a sound effect processing system provided in a microprocessor. The system decodes standard song data from an internal storage or an external storage connected to an extended system interface by a song decoding module; corrects pitches of sing voices by a pitch correcting system, so the pitches of the singing voices are corrected to the pitches of the standard song or close to the pitches of the standard song. The singing voices are processed with harmony adding, tonal modification and speed-changing by a harmony adding system to produce an effect of chorus being composed of three voice parts. A pitch evaluating system is used for comparing the pitch sequence of the singing voices with the pitch sequence of the standard song to draw a voice graph so as to visually show a difference between the pitches of the singing voices and the pitches of the standard song, while providing score and comment of the singing voices. Therefore, a singer can be aware of the effect of his/her performance to immediately so as to increase the amusement in a karaoke singing.

    摘要： The present invention provides a karaoke receiving device which is capable of simultaneously supporting the voice and data signals entering in a wireless manner with two sets of wireless microphones. The singer's voice data are being processed and mixed together with the background music and then transferred to an amplifier or a television or other similar audio devices. It is also possible to control the song selecting, playback, recording and similar karaoke feature by the wireless microphone keypad control. The images and lyrics signals are transferred to a display monitor from the video encoder after the data encoding. In addition, the present invention eliminates the connecting cable between the karaoke microphone and the television and also reduces the size of the microphone. Therefore, the present invention is more convenient and provides a more enjoyable experience for the users.

    摘要： A method of wirelessly transmitting digital signal includes the steps of (a) dividing a digital signal into a primary signal band and a secondary signal band; (b) phrase-shifting the secondary signal to form a reverse signal with respect to the primary signal band in such a manner that the reverse signal is one hundred and eighty degrees out of phrase with the primary signal band; (c) encoding the primary signal band and the reverse signal; (d) wirelessly transmitting the primary signal band and the reverse signal; (e) decoding the encoded primary signal band and the encoded reverse signal; and (f) combining the primary signal band and the reverse signal to re-form the digital signal.
