    摘要: A scheduled recording method, which schedules recording of copy-protected content, is provided. The scheduled recording method involves determining whether copy control information of content of interest exists in a recording device storing various copy control information; if the copy control information does not exist in the recording device, newly receiving copy control information and then determining whether the copy control information exists among the newly received information; if the copy control information of the content exists in the recording device, determining whether the copy control information “copy never”; and if the copy control information of the content is “copy never”, transmitting an error message to a user indicating that the content of interest is not recordable to a user. Accordingly, it is possible to let a user know about whether content is recordable by defining a copy protection status variable and determining whether the content is recordable whenever new copy control information is received.

    摘要: A home domain building method and system that allow devices to join a home domain using smart cards. In the method, a master device reads device information from a smart card having a device ID and a device key as the device information of a guest device authenticated as a legal device and transmits a challenge request signal to the guest device, the guest device randomly generates a challenge value in response to the challenge request signal, the master device encrypts the challenge value using the device key of the guest device and transmits the encrypted challenge value to the guest device, the guest device decrypts the encrypted challenge value, and if the decrypted challenge value is the same as the challenge value generated in response to the challenge request signal, the guest device allows the master device to join the guest device in the home domain.

    摘要: A method and apparatus of protecting digital content within a domain is provided. if a device registered with a domain withdraws from the domain, a domain key used in the domain before withdrawal of the device is updated to a domain key which cannot be used by the device; and the domain key not exposed to the device is transmitted to a plurality of devices currently registered with the domain so that only the currently registered devices have the most recent domain key. Therefore, devices not registered with the domain and devices which previously registered with the home domain but withdrawn from the home domain can be prevented from using digital content currently shared within the domain. In addition, registered devices that withdraw from the home domain may use digital content legitimately downloaded from the home domain before they withdrew from the domain.

    摘要: A method of packaging broadcast contents are provided. The method includes: extracting a copy control bit from input broadcast contents and determining whether the broadcast contents will be stored after being encrypted based on the extracted copy control bit; creating usage rule information which includes an encryption method of the broadcast contents if it is determined that the broadcast contents will be stored after being encrypted; extracting the copy control bit from each new broadcast content sequentially input and detecting broadcast contents which include copy control bits indicating that the broadcast contents will be stored without being encrypted; and encrypting the input broadcast contents through the broadcast contents before the detected broadcast contents using the encryption method and packaging and storing the encrypted broadcast contents and the usage rule information. Therefore, the unauthorized copying of broadcast contents transmitted through a digital broadcast receiver can be prevented.

    摘要: A home network system allowing a user to directly control joining or removing of member devices in a domain using a user interface and to effectively control a status change of the member devices of the domain and a management method therefor. The home network system includes: a master device, which forms a domain with more than one controlled device, transmits a predetermined domain key to the controlled devices included in the domain, generates a new domain key whenever a configuration of the domain is changed, and transmits the new domain key to the controlled devices remaining in the domain; and a control point, which provides a user interface allowing a user to directly change the configuration of the domain.

    摘要: A method and apparatus for managing digital content, which can detect the leakage of an encryption key when the encryption key used for encrypting the digital content is leaked or cracked. When the encrypted digital content is decrypted by an illegal device, a module linked with the encrypted digital content is automatically driven and a digital content managing apparatus is then notified that the encrypted digital content has been decrypted by the illegal device such that the digital content managing apparatus can change the encryption key. Thus, it is possible to prevent the digital content from being continuously leaked due to the use of the same encryption key for encrypting subsequent digital content.
