Method of recording and/or reproducing data under control of domain management system
First Claim
1. A method of recording contents on a storage medium in a computing device comprising a processor having computing device-executable instructions, the contents being recorded in response to a write command input from a domain management system that causes the contents to be used only within a predetermined domain, the method comprising:
- extracting, from the write command, domain management information regarding the predetermined domain and the contents, and copy control information specifying an extent of copying the contents within the predetermined domain;
recording, using the processor, the extracted domain management information on the storage medium;
generating a domain-bound flag that is used to determine whether the recording apparatus which records the contents on the storage medium is present in the predetermined domain, based on the extracted copy control information; and
recording the domain-bound flag and the contents on the storage medium.

Abstract
Provided are a method of recording/reproducing data under control of a domain management system. The method includes extracting, from the write command, domain management information regarding the predetermined domain and contents, and copy control information specifying an extent of copying the contents within the predetermined domain; recording the extracted domain management information on the storage medium; generating a domain-bound flag that is used to determine whether the recording apparatus which records the contents on a storage medium is present in the predetermined domain, based on the extracted copy control information; and recording the domain-bound flag and the contents on the storage medium. Accordingly, it is possible to record contents, recording of which is limited within a predetermined domain, on a storage medium outside a slave under control of a domain management system, while preventing the contents from being reproduced within other domains.

13. A method of reproducing contents in a computing device comprising a processor having computing device-executable instructions, the contents being reproduced from a storage medium under control of a domain management system that causes the contents to be used within a predetermined domain, the method comprising:
-
receiving a read command from the domain management system; reading a domain-bound flag that is used to determine whether reproduction of the contents is limited within the predetermined domain; when the domain-bound flag indicates reproduction of the contents only within the predetermined domain, receiving current domain management information regarding a current domain from the domain management system, and receiving recording domain management information regarding a recording domain in which recording of the contents is performed from the storage medium; determining, using the processor, whether the domain management system belongs to the predetermined domain based on the recording domain management information and the current domain management information; and transmitting the recording domain management information and the contents to the domain management system. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
