Claims

1. An information provision system comprising:

a plurality of information provision devices for providing external-output information, each information provision device including;

memory means for storing data; and

information processing means for using the data stored in the memory means to prepare external-output information;

a transmission unit for conveying external-output information provided by the information provision devices;

a plurality of output terminals in a number greater than the plurality of information provision devices, each output terminal including;

input means by which requests for provision of external-output information are inputted;

request transmission means for transmitting, according to commands inputted via the input means, requests for provision of external-output information; and

information output means for externally outputting information based on external-output information received from an information provision device via the transmission unit; and

a central control device including;

request receiving means for receiving requests transmitted from request transmission means;

a priority storage means for storing, for each output terminal, a priority level at which external-output information is to be provided; and

command means for commanding, according to requests received by the request receiving means and according to priority level stored for requesting output terminals, an information provision device to provide external-output information requested in a request received by the request receiving means.

2. An information provision system as claimed in claim 1, wherein

the transmission unit is a multi-channel transmission unit for conveying external-output information over a plurality of channels that are allotted to respective information provision devices;

each output terminal further includes;

channel selection means connected to the multi-channel transmission unit and for selecting a channel of the plurality of channels; and

channel command means for commanding the channel selection means to select a channel over which external-output information is to be conveyed by the transmission unit;

the information output means externally outputs information based on external-output information received from the multi-channel transmission unit over a channel selected by the channel selection means; and

the central control device further includes channel notification means for notifying a requesting output terminal an allotted channel over which external-output information from a selected information provision device will be transmitted, the channel command means of the requesting output terminal commanding the channel selection means of the requesting output terminal to select a channel accordingly.

3. An information provision system as claimed in claim 2 wherein the command means commands an information provision device based on priority level stored in the priority storage means when the request receiving means receives a plurality of requests within a predetermined duration of time.

4. An information provision system as claimed in claim 3 wherein the central control device further includes a priority level setting changing means for setting and changing priority level stored in the priority storage means for each output terminal.

5. An information provision system as claimed in claim 3 wherein the priority storage means further stores a highest-priority level for a highest-priority output terminal of the output terminals;

and wherein the command means gives priority to a request from the highest-priority output terminal over requests from other output terminals when commanding information provision devices to provide external-output information.

6. An information provision system as claimed in claim 5 wherein the central control device further includes a priority level setting changing means for setting and changing priority level stored in the priority storage means for each output terminal.

7. An information provision system as claimed in claim 5 wherein the plurality of information provision devices further comprises an exclusive information provision device, the exclusive information provision device being fixedly set for executing information processes exclusively for the highest-priority output terminal, the command means commanding the exclusive information provision device to provide external-output information in response to a request from the highest-priority output terminal and commanding an information provision device to provide external-output information in response to a request from an output terminal other than the highest-priority output terminal.

8. An information provision system as claimed in claim 7 wherein the central control device further includes a priority level setting changing means for setting and changing priority level stored in the priority storage means for each output terminal.

9. An information provision system as claimed in claim 2 wherein the priority storage means further stores a highest-priority level for a highest-priority output terminal of the output terminals;

and wherein the command means gives priority to a request from the highest-priority output terminal over requests from other output terminals when commanding information provision devices to provide external-output information.

10. An information provision system as claimed in claim 9 wherein the central control device further includes a priority level setting changing means for setting and changing priority level stored in the priority storage means for each output terminal.

11. An information provision system as claimed in claim 9 wherein the plurality of information provision devices further comprises an exclusive information provision device, the exclusive information provision device being fixedly set for executing information processes exclusively for the highest-priority output terminal, the command means commanding the exclusive information provision device to provide external-output information in response to a request from the highest-priority output terminal and commanding an information provision device other than the exclusive information provision device to provide external-output information in response to a request from an output terminal other than the highest-priority output terminal.

12. An information provision system as claimed in claim 11 wherein the central control device further includes a priority level setting changing means for setting and changing priority level stored in the priority storage means for each output terminal.

13. An information provision system as claimed in claim 2 wherein the central control device further includes a priority level setting changing means for setting and changing priority level stored in the priority storage means for each output terminal.

14. An information provision system as claimed in claim 2 wherein:

each information provision device is a karaoke performance device and the information processing means of said information provision device preparing karaoke performance information by using karaoke data stored in the memory means;

each output terminal is a karaoke terminal,

the request transmission means of said output for transmitting song requests according to songs input inputted via the input means; and

the information output means of said output terminal for outputting sound according to the karaoke performance information; and
