Abstract
Ordinary data groups and index information indicating data names and memory locations of broadcasted data are transmitted in multiplex mode from the data broadcasting station, and received by the onboard terminaland/or the information service stationthrough the data distribution part. The onboard terminaldetects the information which it does not hold by referring to the index information, and presents a list of data names at the onboard display part. The service stationstores separately the data groups and the index information provided from the broadcasting station, and in response to the download request from the onboard, it examines whether the required data is located in SS memory partby referring to the index data, and captures the required data from external memory locations defined in the index information if the required data is not stored.
