Abstract

A contents transfer system which includes a transmitter for transmitting a compressed contents via a network, and a terminal for inputting the contents transmitted from the transmitter via the network and outputting the input contents to a recording/reproducing media according to user'"'"'s specification. A user can acquire the contents within the recording/reproducing media.

Claims

1. A contents transfer system comprising:

a transmitter for transmitting compressed contents via a network;

a company terminal connected to said network for receiving the contents transmitted from said transmitter via the network, and for outputting the contents to a removable recording/reproducing media, said company terminal including;

a first encrypter for first encrypting the received contents;

a recording media for recording the first encrypted contents from said first encrypter;

a first decrypter for first decrypting the first encrypted contents recorded on the recording media; and

a second encrypter for second encrypting the first decrypted contents from said first decrypter with use of an encryption key associated with first individual information assigned to the removable recording/reproducing media, the second encrypted contents from said second encrypter is outputted to the removable recording/reproducing media and stored thereon; and

a user terminal capable of at least reproducing contents read from the removable recording/reproducing media, said user terminal including second decrypter for second decrypting the second encrypted contents downloaded in the removable recording/reproducing media, with use of a decryption key corresponding to the encryption key of the second encrypter,

wherein the decryption key is associated with second individual information assigned to the user terminal, which is paired with the first individual information assigned to the removable recording/reproducing media,

thereby a user can view the downloaded contents in said removable recording/reproducing media on only the user terminal which is paired with the removable recording/reproducing media.

2. A contents transfer system according to claim 1, wherein the first individual information is pre-written on the removable recording/reproducing media and the second individual information is pre-written on said user terminal.

3. A contents transfer system according to claim 1, wherein user information regarding to reproducing the downloaded contents in the removable recording/reproducing media is written on the removable recording/reproducing media.

4. A contents transfer system according to claim 3, wherein a billing for the downloaded contents in the removable recording/reproducing media is decided based on the access information.

5. A contents transfer system according to claim 3, wherein a first billing for the downloaded contents is free when the contents is downloaded to a removable recording/reproducing media a first time, and a second billing for the downloaded contents is decided based on the access information when the contents is downloaded to the removable recording/reproducing media at a second time.

6. A contents transfer system according to claim 3, wherein the downloaded contents in the removable recording/reproducing media is applied with a viewing date limitation.

7. A company terminal according to claim 3, wherein the downloaded contents from the network in said recording media of company terminal is decided based on the user information written in the removable recording/reproducing media.

8. A company terminal connected a network, comprising:

a first encrypter for first encrypting compressed contents via the network;

a recording media for recording the first encrypted contents from said first encrypter onto a recording media;

a decrypter for decrypting the first encrypted contents reproduced from the recording media; and

a second encrypter for second encrypting the decrypted contents from said decrypter with use of an encryption key;

wherein second encrypted contents from said second encrypter is outputted to a removable recording/reproducing media and stored thereon,

the encryption key is associated with first individual information assigned to the removable recording/reproducing media,

the first individual information is paired with a second individual information assigned to a user terminal for reproducing the downloaded contents in the removable recording/reproducing media, and

thereby, the downloaded contents in the removable recording/reproducing media can be reproduced on only said user terminal which is paired the removable recording/reproducing media.

9. A company terminal according to claim 8, wherein user information regarding to reproducing the downloaded contents in the removable recording/reproducing media is written on the removable recording/reproducing media.

10. A company terminal according to claim 9, wherein the downloaded contents from the network in said recording media of company terminal is decided based on the user information written in the removable recording/reproducing media.

11. A company terminal according to claim 8, wherein a billing for the downloaded contents in the removable recording/reproducing media is decided based on the access information.

12. A company terminal according to claim 8, wherein a first billing for the downloaded contents is free when the contents is downloaded to a removable recording/reproducing media a first time, and a second billing for the downloaded contents is decided based on the access information when the contents is downloaded to the removable recording/reproducing media a second time.

13. A company terminal according to claim 8, wherein the downloaded contents in the removable recording/reproducing media is applied with a viewing date limitation.

14. A company terminal connected a network, comprising:

a recording media for recording compressed and first encrypted contents via the network;

a decrypter for decrypting the first encrypted contents reproduced from the recording media; and

an encrypter for second encrypting the decrypted contents from said first decrypter with use of an encryption key;

wherein the second encrypted contents from said second encrypter is outputted to a removable recording/reproducing media and stored thereon,

the encryption key is associated with first individual information assigned to the removable recording/reproducing media, and

the first individual information is paired with a second individual information assigned to a user terminal for reproducing the downloaded contents in the removable recording/reproducing media, and

thereby, the downloaded contents in the second removable recording/reproducing media can be reproduced on only said user terminal which is paired the removable recording/reproducing media.
