The data providing system utilizes the resources of the digital broadcasting and the network efficiently so as to provide data for a great number of users at high efficiency. The system includes a server station (2) for communicating with terminal devices (1) individually via the network (4), and a host station (3) for transmitting the same data to all the terminal devices (1) all at once in real time by the digital broadcasting. Individual data and light-load data are handled by the server station (2), and the information such as load data, which should be shared by the terminal devices are handled by the host station (3).
