摘要

A communication terminal (12a) can request a content server (11) for a partial content on the basis of digest metadata and acquire and reproduce the partial content, thereby reproducing a content digest. Therefore, even in a case where the content digest is to be introduced to another user, only the digest metadata needs to be transmitted to a communication terminal (12b) and neither the content nor any portion thereof needs to be transmitted to the communication terminal (12b).
