Reception terminal simulator, sending schedule making device, reception terminal, data transmission/reception system comprising them

Abstract

In a data transmission system, the situation of a receiving terminal is made known or precisely estimated to control delivery data or prepare a data broadcast schedule, thereby preventing troubles in data transmission. For transmission of data in a data transmission system using one-way communication, the information on transmitted data is controlled in a database and the receive, storage, and delete processing at the receiving terminal is simulated using the information on the data, thereby allowing the situation of the receiving terminal to be known. Using this, the subsequent delivery plan is made or a data delivery schedule is prepared using a simulation result. This realizes an efficient data transmission. The information on data includes an expiry date and conditions for receiving data (such as regions or receiving-terminal types).
