PROBLEM TO BE SOLVED: To quickly access required service by simple operation even when much information service is presented and to simply receive KARAOKE (orchestration without lyrics) even in the presentation of information service. SOLUTION: A program number is described in the header part of a menu object. Two displays consisting of a title and a program number are included in the description of the header. Menues constitute many layers and program numbers are described also in the header parts of menu objects in respective layers. When a program number corresponding to a certain menu is inputted, the corresponding menu is displayed, and when a title in the menu is selected, information service corresponding to the title is started. Namely information service also can be accessed by its corresponding program number similarly to a normal KARAOKE program. |
