<P>PROBLEM TO BE SOLVED: To provide a technology that allows a viewer to estimate the value of unknown content, and pay a fee relative to the estimated value. <P>SOLUTION: A cost corresponding to the value of each section is outputted for each of a plurality of sections that compose the received content. The recipient estimates the value of each section by referring to the cost of each section. Accordingly, the balance between the value and price of the section viewed on a trial basis does not produce a situation markedly different from that anticipated by the recipient, thus preventing dissatisfaction relating to the cost of the section viewed on a trial basis. A benefit is that, since the recipient views the section on a trial basis while having anticipated the value of the section, the recipient is more inclined to trial view unknown content, and the recipient can be expected to view more content by the content producer. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
