Title: Method and architecture for converting mpeg-2 4:2:2-profile bitstreams into main-profile bitstreams
Inventor: CHEN XUEMIN
IPC: H04N7/26
Filed: 2000-02-16
Abstract: A system for converting the color format of a digital video bitstream. The system accounts for the allowable formats of the pre- and post-conversion bitstreams, including quantizer (355) precision level, and whether luma and chroma data have separate quantization matrices (385, 390), or share a common quantization matrix. In a particular implementation, an MPEG-2 4:2:2P  bitstream having a color format of 4:2:2 or 4:2:0 is converted to an MP  bitstream having a color format of 4:2:0. Coding efficiencies are achieved by using the luma quantization matrix (390) to re-quantize the chroma data, and re-using luma motion vectors MV for performing motion compensation (320, 325, 510) of the chroma data. Further efficiencies can be achieved by representing a 4:2:2 reference picture in a 4:2:0 format for converting intercoded frames, and changing the position of a pixel downsizing filter (340) and clip function (335). Adjustment (130, 230, 382), of the quantization precision is provided as required. A transcoding function (800) can also be achieved.

Title: Optical disk and optical disk reproduction apparatus and recording apparatus
Inventor: NISHIUMI SATOSHI
IPC: G11B7/24097
Filed: 2001-12-28
Abstract: An optical disk includes a feature forming area 11 and a criterion recording area 12. The feature forming area 22 is an area provided with physical features used for determining whether it is an authorized optical disk or not. The criterion recording area 12 is an area having recorded therein the data of a determination criterion, i.e., a criterion by which it is determined whether the optical disk has been produced in an authorized manner or not on the basis of the physical feature.      An optical disk reproduction apparatus detects the physical features provided in the feature forming area 11, and reads the determination criterion recorded in the criterion recording area 12. Furthermore, based on the determination criterion which has been read, the optical disk reproduction apparatus determines whether or not the detected physical features are those provided for an authorized optical disk. Thus, the optical disk reproduction apparatus can determine whether or not the optical disk has been copied in an unauthorized manner.

Title: System and method for equalizing power from two power sources
Inventor: JANSEN ARIAN
IPC: H02J1/10
Filed: 2000-03-10
Abstract: A system (30) and a method may use variable-frequency power sources for sup-plying power to a load (36). The system and method use phase detection in order to automatically and substantially equalize the currents supplied to a load by each of the variable-frequency power sources, and to cancel a ripple component of the input current drawn by the system. First and sec-ond power sources (31, 32) supply power to the load. The power sources have a similar relationship between their respective variable switching frequencies of, respec-tively, the first and second power sources are locked to one another using phase de-tection to substantially equalize the power supplied to the load by each power source. The system and method are advantageously utilized to provide a power factor correc-tion front-end for a switch-mode power sup-ply. Power sources with non-linear and/or inverse relationships between power sup-plied and switching frequency can be used. In alternate embodiments power from se-ries power sources is equalized by equalizing voltages supplied by each power source to a load.

Title: Method of designing password-based authentication and key exchange protocol using zero-knowledge interactive proof
Inventor: NYANG DAE HUN
IPC: H04L9/32
Filed: 2002-06-04
Abstract: A protocol designing method that securely performs a password-based authentication and key exchange protocol using a zero-knowledge interactive proof is disclosed. According to this method, various kinds of system parameters required for authentication are first set. Then, a user selects a certain random number in conformity with the set parameters, and sends to a server a message including a user ID, a test number A applying a one-way function, and a first question number generation value X known only to the server and the user. The server, using the message sent from the user, sends to the user a message including an authentication Auth of whether the server possesses a public key, and a second question number generation value Y known only to the server and the user. The user authenticates the server by verifying the authentication Auth, and computes a resultant value c of a secret coin tossing known only to the server and the user and a session key SK. Thereafter, the user sends to the server a witness number B for user authentication. The server that stores a password verifier V for the respective user verifies the witness number B using the value c, and exchanges the session key SK by computing the session key SK. Accordingly, a secure authentication and key exchange can be performed only using the password without the necessity of any tool such as a smart card.
