Abstract

PURPOSE:To reduce communication cost by providing the software of a function for synthesizing and reproducing a routine data corresponding to a transmission range to the information transmitted from a transmission side to the terminal equipment of a receiving side. CONSTITUTION:For instance, when a meteorological data 1 is transferred, the terminal equipment 3 of a transmitting side envelopes a range to be transmitted by symbols 2a1-2a4. At this time, the information of the latitude and the longitude of the symbols 2a1-2a4 and only the meteorological 1d information are transmitted by the incorporated data of a transmitting side file 4, respective latitude line 1a, longitude line 1b, geography 1c or the like are not transmitted. In the terminal equipment 5 of a receiving side, the geography 1c enclosed, with the latitude and the longitude of symbols 2a1-2a4, and the latitude 1a and the longitude 1b are drawn from the incorporated data in a receiving side file 6, overlapped with the information 2 transmitted from the terminal equipment 3 of the transmitting side, synthesized and reproduced. Thereby, the profitability is improved and the occupying time of a transmission network can be shortened.
