PURPOSE: To construct a multi-zone/multi-channel guide system by adding a slight change to an infrared sending unit including plural sending channels which are used in a simultaneous interpretation conference system. CONSTITUTION: Plural sending channels of an infrared sending unit 100 are assigned to plural allotting zones, and plural channels are assigned to every allotting zone. For instance, the guide signals are allotted to plural display blocks 1 to 4 through a single unit 100. The same language is sent to the same channels of every display block and a display observer can look on the display blocks with a receiver 5 kept set at the channel of his understandable language. A conventional receiver 5 is available as it is. In addition, the numbers of zones and channels are decided so that the same test oscillation frequency is assigned to the same channels of every display block for the benefit of adjustment of the unit 100. |
