Abstract
A broadcast content that is at least a part of an original content is broadcasted, and a differential content, which is at least a part of the original content, is transmitted in response to a request from a reception terminal. The differential content and the broadcast content are merged with each other to reproduce a perfect original content. Therefore, the perfect original content can be obtained at low price and in short time even when the original content contains a large amount of data.
