Abstract
A content transmitter apparatus is provided which decides whether to permit a content receiver apparatus at a content transmission destination to retransmit content to another content receiver apparatus located inside a house and transmits to the content receiver apparatus the content along with an identifier indicating a permission or prohibition of the content retransmission. A content receiver apparatus is also provided which, when it receives encrypted content from the content transmitter apparatus, checks an identifier received together with the content in executing the content retransmission to another content receiver apparatus located outside the house. If the identifier is found to permit the content retransmission, the content receiver apparatus encrypts and retransmits the content to the outside-house content receiver apparatus. If the identifier is found to not permit the content retransmission, the content receiver apparatus does not retransmit the content to the outside of the house.
