Abstract: A content distribution apparatus generates a group of contents to be sent to a content display apparatus that can continuously display contents of the same attribute. When a first content is newly added to the group, the content distribution apparatus determines the attribute of the first content as the attribute of the group. When adding a second content to the group, if the attribute of the second content coincides with the attribute of the group, the content distribution apparatus adds the second content to the group. The content distribution apparatus sends a content included in the group to the content display apparatus.
