PURPOSE: To provide a communication KARAOKE system in which the work load during a system version-up, for example, is reduced. CONSTITUTION: When a system is newly introduced or a version-up is executed, a system program is distributed together with its version management information to each KARAOKE terminal from a host computer. A CPU 22 in the KARAOKE terminal stores the received system program as well as the version management information in a hard disk 24. When an old version system program is already stored, a new system program is added. Moreover, the version management information is written into a version management table in the disk 24. Starting with a next time, the latest program is executed while referring to the table and a music reproducing is conducted. |
