PROBLEM TO BE SOLVED: To provide a communication KARAOKE (orchestration without lyrics) system which reduces communication time between a host device and a KARAOKE playing terminal and reduces communication cost. SOLUTION: A host device H switches a line switching device K installed in a KARAOKE shop, performs extension connection of a specific KARAOKE performing terminal S connected to it and downloads KARAOKE data to the terminal S according to prescribed distribution procedures. At this communication opportunity, the terminal S uploads its own operation record data and the operation record data of another KARAOKE playing terminal C which are preliminarily collected to the host device. The terminal S stores the downloaded KARAOKE data, also switches the line switching device K to perform extension connection of the terminal C and transfers the downloaded KARAOKE data to the terminal C according to the procedures following the distribution procedures. |
