摘要： The data structure includes a navigation area of a computer readable medium storing navigation data associated with a data stream representing a portion of at least one reproduction path. The navigation data includes indication information, and the indication information indicates whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path. If the indication information indicates the data stream represents multiple reproduction paths, the navigation data includes path number information and an indicator associated with each reproduction path. The path number information identifies a number of the multiple reproduction paths, and each indicator indicates a file associated with the associated one of the multiple reproduction paths.

摘要： The present invention relates to method and apparatus of recording/reproducing a non-MPEG formatted digital TV broadcast signal on/from a writable medium. The present recording method, when a digital TV broadcast signal composed of DirecTV transport packets is received, collects DirecTV transport packets as adding receiving time information to each packet optionally, slices the collected packets into 184-byte stream pieces, composes a Transport Packet defined in MPEG standard with each piece, and writes a series of Transport Packets on a recording medium. The present method can record a non-MPEG type of transport stream in MPEG recording format and reproduce the recorded transport stream to original DirecTV transport stream, whereby an applicability of a digital recorder is improved.

摘要： A method for managing copy protection information of a recording medium is disclosed. Copy protection information for decrypting A/V data encrypted and recorded in a data area of an optical disc is recorded in a key locker of the disc. Information of makers that have manufactured optical disc drives, drive maker keys of each maker and flags indicating whether drive keys are valid or not is included in association with each other in the key locker. To reproduce the A/V data, the copy protection information is read and decrypted by comparing a drive key managed in the optical disc drive with the key renewal information recorded in the optical disc. Accordingly, illegally duplicated optical disc drives can no longer perform a normal playback operation, thereby effectively suppressing illegal duplication of optical disc drives, which also prevents optical disc drives of all makers from being duplicated at once.

摘要： A copy protection method and a copy protection system are disclosed. The system includes a private key verifier receiving a media certificate that includes a private key identification of a compliant playing device and searching for an actual private key corresponding to the private key identification, an intermediate key decryptor receiving an encrypted intermediate key and decrypting the intermediate key with the actual private key, a media key decryptor obtaining an original media key by decrypting the decrypted intermediate key with a media identification; and a media data decryptor receiving an encrypted media data set and decrypting the media data set with the original media key. The method and system of the present invention are applicable to all types of digital media data, and it makes no assumption of any specific media properties. The primary goal of the present invention is to significantly reduce the possibility of making any illegal copies on any nonstandard equipment and is to restrict the media data transfers only to authorized entities.

摘要： Provided is a low-complexity and low-power-consumption turbo decoder with a variable scaling factor. The performance of the turbo decoder is enhanced by evaluating a decoding convergence degree of the turbo decoder using a sign difference ratio (SDR) value, limiting the iterative-decoding number, and calculating and applying a variable scaling factor producing optimal performance in each decoding convergence area based on the SDR value, and power consumption is reduced by reducing the average number of decoding iterations. Thus, the performance degradation when the encoded block is large, which is a shortcoming of a conventional EMLMAP algorithm, can be prevented, the average number of decoding iterations can be reduced, and accordingly power consumption can be reduced.

摘要： The present invention discloses a bearing assembly capable of assuring mechanical strength and reducing a friction coefficient and stress concentration, and a method for manufacturing the same. The present invention comprises a spherical journal and a hemispherical bearing that is made of a fiber reinforced composite and has a bearing surface for establishing a spherical pair with the spherical journal. The fiber reinforced composite can be constructed by arranging a uni-directional prepreg, woven fiber prepregs and staple-fiber prepregs in a variety of configurations, and thermoplastic resin particles or self-lubrication particles are uniformly provided on the bearing surface. It is possible to alleviate stress concentration generated on the bearing surface by forming a plurality of air channels capable of imparting directivity on an outer surface of the hemispherical bearing.
