摘要： PROBLEM TO BE SOLVED: To enable to transmit an incoming message, guaranteed for transmission time order at a low communication cost, when a message of a viewer is transmitted distributedly in an two-way television service. SOLUTION: The two-way television shopping system comprises a broadcasting station device for broadcasting screen data of an two-way service program, a user terminal which receives a broadcast signal and generates a message for buy request, based on the product reference information of the interactive service program and then transmits the generated message, and an interactive service facility for receiving the message for buy request. The broadcast station device 11 broadcasts the screen data, attached with a hashed value. On the user terminal 21 side, the hashed value of the screen data is extracted 225, when the user decides to buy, then the hashed value is added to the message for buy request, and the message for buy request attached with the hashed value is transmitted. Then, a two-way service facility 41 extracts the hashed value from the message for buy request attached with the hashed value, and then compares the extracted hashed value with a hashed value notified in advance from the broadcast station device, to confirm 45 the time the message for buy request was generated.

摘要： PROBLEM TO BE SOLVED: To achieve effective provision for broadcast information having high appeal to a number of unspecified viewers in an interactive broadcast viewing technique.
SOLUTION: Information 21 about viewers who use interactive services and commodity information 22, including target viewer information of this commodity, guided by a data broadcast program are stored. Transfer data of program identification information 81 and viewer identification information 82 which are transmitted from a viewer side receiver 30 for each of a number of unspecified viewers are received in a central process unit 10 when using the interactive services. Statistical viewer information 90 about the viewers of the program is calculated on the basis of the information 21 and the transferred data. Optimal products are selected for a number of unspecified viewers on the basis of the information 22 and 90. After that, the selected optimal commodity information is provided to a number of unspecified viewers via a data broadcast system 60. Thus, broadcast information such as effective product information having high appeal to a number of unspecified viewers is provided.
