PURPOSE:To attain easy transmission of emergency information by providing a separating part to separate an information-sorting signal branched from a reception part and an information-sort selecting part, setting a sound-volume by means of the information sorting signal selected by the said information sorting and selecting part to display it in a display part, and thereby making use of a community television receiving line. CONSTITUTION:A high frequency signal in which sound and others are modulated through the community television receiving line 6 is branched from the part of the reception part 7. And the information sorting signal is separated from the separating part 1. The said signal enters the information-sort selecting part 2, where the information-sort is selected, and this signal enters the sort of information displaying part 3 and displays the sort of the information. The information sorting signal selected by the part 2 enters a sound selecting and varying part 4, and the part 4 sets the degree of sound amplification at a sound volume amplifying part 5 by means of a sound varying signal. In case of an emergency information, a top priority is given to the information sorting signal, and the said magnitude at the part 5 is maximized, when the part 3 displays and holds the sort of information. As a result, the broadcasting of an important information is made noticeable. |
