Abstract
A content distribution system is provided in a pseudo closed space like public facilities or establishments. The content distribution system includes a content distribution apparatus distributing content formed of digital information, and a plurality of users present within the pseudo closed space use respective portable content reception apparatuses to receive and reproduce the content. The content distribution apparatus also distributes a signal for enabling the content to be reproduced continuously by the content reception apparatus. Even if the content reception apparatus has received the content, it cannot reproduce the content when its user leaves the pseudo closed space and accordingly the reception apparatus cannot receive that signal from the content distribution apparatus.
