PROBLEM TO BE SOLVED: To provide an information useful for a user. SOLUTION: A control device stores required programs selected and specified by a user in a memory for a prescribed time (S1 to S3). A registered singer name corresponding to each requested program stored in the memory is retrieved and each singer name is counted (S4, S5). After retrieving the singer names of all requested programs and counting of the singer names in each name (S6), a singer name having high frequency is detected (S7), programs belonging to the singer name are extracted as programs highly correlated with the requested programs to prepare a program list (S8). The program list is displayed on a display in the idle time of KARAOKE performance as information service for the user. |
