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

1-5. -5. (canceled)

6. A data receiving apparatus comprising:

receiving means for receiving a plurality of types of data for transmission and for receiving, when specific data which requires an authentication process for confirming the validity of an apparatus of a data transfer destination is contained in the data for transmission, determination data used to determine that said specific data is contained;

determination means for determining whether or not said specific data is contained in said data for transmission on the basis of the determination data received by the receiving means;

judging means for performing, if said determination means determines that said specific data is contained, said authentication process with the apparatus of said transfer destination, and judging whether or not the apparatus of said transfer destination is a valid apparatus to which said specific data may be downloaded; and

means for transferring said specific data to the apparatus of said transfer destination if the judging means confirms that the apparatus of said transfer destination is a valid apparatus.

7. A data receiving apparatus according to claim 6,

wherein said specific data is multiplexed together with a plurality of types of other data for transmission and is transmitted, and

wherein said determination data is added to information representing the relationship between the specific data in the multiplexed data and identification information for each specific data.

8. A data receiving apparatus according to claim 6,

wherein said specific data is data compressed by a predetermined compression method, and

wherein the apparatus of said transfer destination is capable of recording said specific data maintained in a compressed state.

9. A data receiving method of data receiving apparatus comprising:

receiving a plurality of types of data for transmission and receiving, when specific data which requires an authentication process for confirming the validity of an apparatus of a data transfer destination is contained in the data for transmission, determination data used to determine that said specific data is contained;

determining whether or not said specific data is contained in said data for transmission on the basis of the received determination data;

performing, by the data receiving apparatus and if it is determined that said specific data is contained, said authentication process with the apparatus of said transfer destination, and judging whether or not the apparatus of said transfer destination is a valid apparatus to which said specific data may be downloaded; and

transferring said specific data to the apparatus of said transfer destination if it is confirmed that the apparatus of said transfer destination is a valid apparatus.

10. A data receiving method according to claim 9,

wherein said specific data is multiplexed together with a plurality of types of other data for transmission and is transmitted, and

wherein said determination data is added to information representing the relationship between the specific data in the multiplexed data and identification information for each specific data.

11. A data receiving method according to claim 9,

wherein said specific data is data compressed by a predetermined compression method, and

wherein the apparatus of said transfer destination is capable of recording said specific data maintained in a compressed state.

12. A data transmission and reception system comprising:

a data transmission apparatus comprising data creation means for creating a plurality of types of data for transmission and for creating, when specific data which requires, in a transmission destination, an authentication process for confirming the validity of an apparatus of a data transfer destination is contained in the data for transmission, determination data used to determine that said specific data is contained; and

transmission means for transmitting data which is created by the data creation means, and

a data receiving apparatus comprising receiving means for receiving data transmitted from the transmission means of said data transmission apparatus;

determination means for determining whether or not said specific data is contained in said data for transmission on the basis of the determination data contained in the data received by the receiving means;

judging means for performing, if said determination means determines that said specific data is contained, said authentication process with the apparatus of said transfer destination, and judging whether or not the apparatus of said transfer destination is a valid apparatus to which said specific data may be downloaded; and

means for transferring said specific data to the apparatus of said transfer destination if the judging means confirms that the apparatus of said transfer destination is a valid apparatus.

13. A data transmission and reception system according to claim 12,

wherein said specific data is multiplexed together with a plurality of types of other data for transmission and is transmitted, and
