Abstract

A data reproducing method, data recording/reproducing apparatus and data transmitting method are disclosed. The present invention includes the steps of providing information for identifying a player to a server, downloading data based on the information from the server and reproducing the data. And, the present invention includes the steps of receiving information for identifying a player from the player, configuring data using the information, and transmitting the data to the player. Accordingly, content can be protected against illegal copy, illegal distribution and the like by employing player information. And, the present invention can trace a player having compromised content.

Claims

1. A method of reproducing data, comprising the steps of:

providing information for identifying a player to a server;

downloading data based on the information from the server; and

reproducing the data.

2. The method of claim 1, wherein the information is stored in a memory unit within the player.

3. The method of claim 2, wherein the memory unit is ‘

Player Status Register (PSR)’

.

4. The method of claim 1, wherein the data is configured reproducible using ‘

device keys’

of the player.

5. The method of claim 1, wherein the data is configured reproducible using ‘

sequence keys’

of the player.

6. A data recording/reproducing apparatus comprising;

a storage device storing downloaded data;

a memory unit storing information for identifying the apparatus; and

a controller providing the information to a server, the controller downloading data configured using the information from the server.

7. The apparatus of claim 6, wherein the memory unit is ‘

Player Status Register (PSR)’

.

8. The apparatus of claim 6, wherein the data is configured reproducible using ‘

device keys’

of the apparatus.

9. The apparatus of claim 6, wherein the data is configured reproducible using ‘

sequence keys’

of the apparatus.

10. A method of transmitting data, comprising the steps of:

receiving information for identifying a player from the player;

configuring data using the information; and

transmitting the data to the player.

11. The method of claim 10, wherein the information is stored in a memory unit within the player.

12. The method of claim 11, wherein the memory unit is ‘

Player Status Register (PSR)’

.

13. The method of claim 10, wherein the data is configured reproducible using ‘

device keys’

of the player.

14. The method of claim 10, wherein the data is configured reproducible using ‘

sequence keys’

of the player.

15. A data recording/reproducing apparatus comprising a memory unit wherein information for identifying the apparatus is stored in the memory unit.

16. The apparatus of claim 15, wherein the memory unit is ‘

Player Status Register (PSR)’

.
