Claim 7

A karaoke terminal apparatus according to claim 4, further comprising video synthesizer means for processing lyric information contained in the received song data piece so as to produce lyric characters of the requested karaoke song.

Claim 8

A karaoke terminal apparatus according to claim 4, further comprising memory means connected between the receiver means and the audio synthesizer means for storing the received song data piece.

Claim 9

A karaoke network system for providing a plurality of song data, the karaoke network system comprising: a central station for serving the plurality of song data; a communication network connected to the central station, the communication network having multiple channels for receiving the plurality of song data; and a karaoke terminal connected to the central station through the communication network to selectively receive one of the plurality of song data to present a desired karaoke song on the karaoke terminal in response to a local request command used in the karaoke terminal; wherein the central station includes a transmitter that sorts and divides the plurality of song data into multiple groups that contain a group of the plurality of song data, the multiple groups corresponding in number to the multiple channels so that each of the multiple groups of the song data are successively transmitted in a corresponding one of the multiple channel in an continuous manner; and wherein the karaoke terminal includes a receiver that selects one of the multiple channels designated by the local request command and receives one of the plurality of song data specified by the local request command from the selected channel so that the karaoke terminal can present the desired karaoke song according to the received song data.

Claim 10

A karaoke network system for providing a plurality of song data, the karaoke network system comprising: a central station for serving the plurality of song data; a communication network connected to the central station, the communication network having multiple channels for receiving the plurality of song data; and a karaoke terminal connected to the central station through the communication network to selectively receive one of the plurality of song data to present a desired karaoke song on the karaoke terminal in response to a local request command used in the karaoke terminal; wherein the central station includes a transmitter that sorts and divides the plurality of song data into multiple groups that contain a group of the plurality of song data, the multiple groups corresponding in number to the multiple channels so that each of the multiple groups of the song data are successively transmitted in a corresponding one of the multiple channel in an continuous manner; and wherein the karaoke terminal includes a receiver that selects one of the multiple channels designated by the local request command and receives one of the plurality of song data specified by the local request command from the selected channel so that the karaoke terminal can present the desired karaoke song according to the received song data.

Claim 11

A karaoke network system according to claim 7, wherein the karaoke terminal includes an input circuit for inputting the local request command, the local request command indicating a channel number effective to designate one channel of the multiple channels and a song code that specifies one of the plurality of song data that is divided into one of the multiple groups assigned to the one channel designated by the channel number.

Claim 12

A karaoke network system according to claim 7, wherein the plurality of song data are divided into the number of multiple groups corresponding to the number of channels to minimize a maximum waiting period to cycle through the entire plurality of song data such that the maximum waiting period is approximately determined by a time to cycle through the entire plurality of song data over a single channel divided by the number of the multiple groups.
