摘要

PROBLEM TO BE SOLVED: To realize various services by allowing a pay broadcast system to up-link application data together with view history information. SOLUTION: View history information to impose charging on viewers is stored in an area 41 of transmission data and sent periodically to a transmitter side via a telephone line or the like. In the case that application data are generated by the user, the data are stored in an area 43 so as to set data denoting the presence of the application data to an area 42. When the area 42 at a reception terminal equipment is set with data denoting the presence of the application data in the area 43, the data are sent to the transmitter side independently of a periodic timing. Since the data in response to the application are stored in the area 43, various services such as TV shopping or mail distribution are realized.
