Abstract
The protection of data against illicit transfer with respect to specific data can be ensured. An integrated receiver decoder determines whether or not ATRAC (Adaptive Transform Acoustic Coding) data requiring authentication is contained in selected piece-of-music data in accordance with determination data added into transmitted data. When ATRAC data requiring authentication is contained, the integrated receiver decoder performs an authentication process between it and a storage which is a transfer destination of the ATRAC data, and performs downloading of the ATRAC data after confirming that the storage is a valid apparatus to which the downloading may be performed.
