Abstract

A karaoke network system includes a host computer and a plurality of karaoke stations connected to the host computer via a communication line. When a new karaoke station is added to the karaoke network system or when a system program to be used by each of the karaoke stations is upgraded, a new system program is distributed from the host computer to the specified karaoke stations, Each of the karaoke stations has a first storage device for storing the new system program received from the host computer, and a second storage device that stores a system program currently executed to operate each of the karaoke stations. After rebooting each of the karaoke stations and thereafter, each of the karaoke stations is operated with the newest system program.

Claims

1. A method of operating a karaoke network system including a communication line, a host computer and a plurality of karaoke stations connected to the host computer via the communication line, the method comprising the steps of:

transmitting a system program from the host computer via the communication line to at least one of the plurality of karaoke stations;

transmitting song program data from the host computer via the communication line to at least one of the plurality of karaoke stations;

wherein the system program and the song program data are independently transmitted via the communication line to the at least one of the plurality of karaoke stations; and

executing within the at least one of the plurality of karaoke stations the system program supplied from the host computer to generate a sound in accordance with the song program data.

2. A method of operating a karaoke network system according to claim 1, further comprising the step of receiving the system program by a first storage area provided separately from a second storage area, the second storage area storing an old system program that is currently operating each of the karaoke stations.

3. A method of operating a karaoke network system according to claim 2, further comprising the steps of rebooting the at least one of the plurality of karaoke stations thereby selecting for execution a newest version of the system program;

and

executing within the at least one of the plurality of karaoke stations the newest system program.

4. A method of operating a karaoke network system including a communication line, a host computer, and a plurality of karaoke stations connected to the host computer via the communication line, the method comprising the steps of:

transmitting a system program from the host computer to at least one of the plurality of karaoke stations;

storing a first system program in the at least one of the plurality of karaoke stations which is currently executed;

receiving a second system program in the at least one of the plurality of karaoke stations that is transmitted from the host computer; and

detecting an operational state of the at least one of the plurality of karaoke stations and, upon detecting an appropriate operational state in which the at least one of the plurality of karaoke stations is not reproducing songs, causing the at least one of the plurality of karaoke stations to execute the second system program.

5. A method of operating a karaoke network system according to claim 4, wherein the step of causing the at least one of the plurality of karaoke stations to execute the second system program includes the steps of:

rebooting the at least one of the plurality of karaoke stations after the at least one of the plurality of karaoke stations has received the second system program;

reading out the second system program; and

rewriting the second system program to replace the first system program.

6. In a karaoke network system including a communication line, a host computer, and a plurality of karaoke stations connected to the host computer via the communication line, the improvement comprising:

a system program transmission device that transmits a system program from the host computer to at least one of the plurality of karaoke stations;

a song program data transmission device that transmits song program data from the host computer to at least one of the plurality of karaoke stations independently of transmission of the system program;

a boot storage device in each of the plurality of karaoke stations that stores a boot program;

a first storage device in each of the plurality of karaoke stations that stores a first system program;

a system program receiving device in each of the plurality of karaoke stations that receives a second system program that is transmitted from the host computer; and

a second storage device in each of the plurality of karaoke stations that stores the second system program.

7. A karaoke network system according to claim 6, wherein at a time of reboot after the at least one of the plurality of karaoke stations has received the second system program, the at least one of the plurality of karaoke stations reads out the second system program from the second storage device according to the boot program, rewrites the second system program in the first storage device for replacing the first system program, and operates the at least one of the plurality of karaoke stations according to the second system program.

8. A karaoke network system comprising:

a communication line;

a host computer, the host computer including a system program transmission device that transmits a system program and a song data transmission device that transmits song data; and

a plurality of karaoke stations connected to the host computer via the communication line, each of the plurality of karaoke stations including;

a boot storage device in each of the plurality of karaoke stations that stores a boot program;

a memory area in each of the plurality of karaoke stations that stores a first system program that is executed to allow each of the plurality of karaoke stations to reproduce sound according to the song data;

a system program receiving device in each of the plurality of karaoke stations that receives a second system program transmitted from the host computer;

a system program storage area in each of the plurality of karaoke stations that stores the second system program;

an automatic reboot system, operable after the system program receiving device receives the second system program and when an associated karaoke system is not reproducing sound, the automatic reboot system causing an associated karaoke station to reboot and to reproduce sound according to the song data and the second system program.

9. A karaoke network system according to claim 8, wherein the memory area is formed by a first memory device and the system program storage area is formed by a second memory device separated from the first memory device.

10. A karaoke network system according to claim 8, wherein the memory area and the system program storage area are within a single memory device.

11. A karaoke network system according to claim 8, wherein each of the plurality of karaoke stations further comprises:

a sound reproducing device that reproduces a song representative of the song data supplied from the host computer;

a microphone that picks up vocal sound; and

a sound mixer device that mixes the song reproduced by the sound reproducing device and the vocal sound that is supplied from the microphone.

12. A karaoke network system according to claim 11, wherein at a time of reboot after at least one of the plurality of karaoke stations has received the second system program, the at least one of the plurality of karaoke stations reads out the second system program from the second storage device according to the boot program, rewrites the second system program in the first storage device for replacing the first system program, and executes at least one of the plurality of karaoke stations according to the second system program.
