ABSTRACT:
A data reproducing apparatus includes a receiver receiving the content and outputting the received content to an image display apparatus prepared in advance, and a transmitter transmitting the content to the receiver when authentication of the receiver is successful. Before transmitting the content, the transmitter transmits a request to start authentication to the receiver and executes an authentication process after a predetermined time. When the receiver cannot be authenticated, the transmission of the request to start authentication and the execution of the authentication process are repeated. Here, the predetermined time is variably set according to the number of times the request to start authentication is transmitted and the authentication is executed.
