发明名称 CONTENT SUPPLY SYSTEM AND INFORMATION PROCESSING METHOD
摘要 <p>A center (content supply center) (1865) for storing/managing a content is connected to user terminals (1861-1864) used by users through networks (861-867). The center (1865) sends a signal of a content for trial viewing/listening to a user terminal free or at a low price. The user terminal (1861-1864) receives the signal, and the user can select, purchase, and reproduce at high quality only the content that the user likes. Thus trial viewing/listening is possible, and the opportunity to purchase a content is enhanced since it is unnecessary to download a large amount of data with high quality from a content supply center.</p>
