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.

Claims

1. A receiver apparatus, comprising:

a receiver for receiving a digital signal including a plurality of content programs, record jacket image data associated with at least some of the plurality of content programs, and text data of titles associated with at least some of the plurality of content programs;

an external digital data interface operable to connect to an external storage device for enabling communication with the external storage device;

a display for displaying the record jacket image data and the title text data associated with at least one selected downloadable content program to a user;

means for obtaining the at least one selected downloadable content program when the displayed record jacket image data or the title text data is selected;

authentication judgment means for judging, based on a transfer request by a user, whether authentication can be established between the receiver apparatus and the external storage device before transferring the obtained content program and the record jacket image data associated therewith from the receiver apparatus to the external storage device via the external digital data interface; and

transferring means for transferring the obtained content program and the associated record jacket image data to the external storage device if the authentication is established;

wherein the transfer request by the user is made based upon at least one of the displayed record jacket image data and the title text data.

2. The receiver apparatus of claim 1, wherein the transferring means transfers the obtained content program to a first data area of the external storage device and transfers the record jacket image data to a second data area of the external storage device.

3. The receiver apparatus of claim 1, wherein the record jacket image data and the title text data comprise accompanying information received by the receiver as part of the digital signal.

4. The receiver apparatus of claim 3, wherein the accompanying information further includes lyrics data and explanation data.

5. The receiver apparatus of claim 1, wherein the authentication judgment means judges whether the authentication can be established when specific data about the authentication is included in the obtained content program.
