Abstract: PROBLEM TO BE SOLVED: To provide a karaoke apparatus for overcoming a problem such that a singer is too strongly aware that next karaoke singing is recorded on a CD and can not sing well, by allowing the CD to be made after singing.
SOLUTION: The karaoke main apparatus 1 is connected to a HDD file server 8 on which a mass storage HDD is installed and records all karaoke songs played and sung. After the singer sings, the singer instructs to make the CD of favorite singing, and the HDD file server 8 drives a CD-R drive 9, writes a voice data of the instructed karaoke singing on a blank CD and makes the CD.

Abstract: PROBLEM TO BE SOLVED: To provide a KARAOKE device which can easily control whether or not music data can be played. SOLUTION: Even music data of managed songs which need not be permitted to be played by pieces of music and KARAOKE devices are stored on a hard disk similarly to music data of other KARAOKE songs. Then ROMs 20 stored with key data for allowing the managed songs to be played are manufactured by the managed songs and the KARAOKE devices and sets in a KARAOKE device to permit the managed songs to be played. Consequently, the KARAOKE device need not have media such as a CD-ROM by the managed songs and the copyright holders of the managed songs can physically manage the numbers of permitted cases by the ROMs 20.

Abstract: PROBLEM TO BE SOLVED: To provide a KARAOKE network system which simplifies the constitution of a KARAOKE terminal side and never makes service contents worse. SOLUTION: Multiple KARAOKE terminals 30 and a common center station 20 are connected by a LAN 10 and a KARAOKE terminal requests music data on desirable music to be played from the center station. The center station 20 transfers the music data corresponding to the request to the requesting terminal 30. Independently of the transfer of the music data, the center station 20 continue to distribute video data of multiple channels at any time. Consequently, the music is reproduced on the terminal side according to the musical sound data included in the music data, text images are reproduced according to the text data, and video data are selected according to video channel specification data to reproduce moving picture video.

Abstract: PURPOSE:To provide a KARAOKE network system simplified in the constitution of a KARAOKE terminal side without degrading service content. CONSTITUTION:Plural KARAOKE terminals 30 are connected to a common center station 20 with an LAN 10, and the KARAOKE terminal requests the music data of a desired music to the center station 20. The center station 20 transfers the music data corresponding to the request to the terminal 30 which requests it. Also, the center station 20 always continues to transmit the video data of plural channels independently of the transfer of the music data. Thus, the terminal side can reproduce the music based on musical data included in the music data, reproduce song word pictures based on song word data, and reproduce an animation video by selecting the video data based on video channel designation data.

Abstract: PURPOSE:To eliminate zero cross distortion with simple constitution and to expand the dynamic range by applying DA conversion in a form of zero point shift based on a digital bias data. CONSTITUTION:An LSB-MSB data SD is inputted to a register 10 and converted into a parallel data PD. The data PD is fed to an adder 12, in which the data is added with a bias data BD from a generator 14. The added data SFD is fed to a selector 16 as an input A and the data PD is fed as an input B and the data selection is controlled in response to a selection control input. A compa rator 18 compares the data PD with a reference data D40. A comparison output CO is fed to the selector 16 as a selection control input. A current output DAC20 DA-converts an output data SO from the selector 16. The switching operation of a changeover circuit 22 is controlled in response to the output CO and an analog signal corresponding to the input is obtained.
