摘要： An apparatus for identifying the address in pregroove (ADIP) of a Blu-ray disc is described. The apparatus uses a statistical scheme or distance-finding scheme to find the position of a predetermined minimum shift keying (MSK) mark or the first MSK mark, i.e. a bit sync unit, from an ADIP unit to identify data of the ADIP unit. The present invention doesn't have the error propagation effect occurring in the prior art so that the error rate for ADIP identification can be greatly reduced.

摘要： A modulation method for symbols in a frame of a compact disc includes the steps of receiving a plurality of data words, modulating each data word into a code word of a corresponding data symbol, and providing a plurality of combinations of potential merge bits to be inserted between successive symbols of the frame. At least one combination of candidate merge bits is generated according to the plurality of combinations of potential merge bits, a data symbol immediately preceding the location of the candidate merge bits, and a data symbol immediately succeeding the location of the candidate merge bits. The combination of candidate merge bits which minimizes (optimizes) the absolute cumulative DSV is selected when a subsequent group of possible combinations of candidate merge bits is detected or after a predetermined delay, and the selected combination of candidate merge bits is inserted between the two successive data symbols.

摘要： An apparatus for data recovery includes a multi-level comparison unit, a detection logic unit, and a data composer. The multi-level comparison unit compares an input signal with M different reference signal levels to generate M digital data, the number M being greater than or equal to 2. The detection logic unit is coupled to the multi-level comparison unit, and performs logic operations upon specified lengths over the M digital data obtained from the multi-level comparison unit. The data composer is coupled to the multi-level comparison unit and the detection logic unit. The data composer generates recovered data conforming with a run length encoding constraint based on the M digital data obtained from the multi-level comparison unit and the result obtained from the detection logic unit.

摘要： A system and method is provided to automatically associate type-specific information with a document of a prescribed type. The type information includes instance-specific type information that can be instantiated to each document of the prescribed type. The type information also includes generic type information that is automatically applied to all documents of the prescribed type. Such generic type information includes policies that govern, for example, the life span of the documents or who can access the documents. Instance-specific type information can be demoted to and promoted from a document of the prescribed type. Generic type information can only be demoted to a document of the prescribed type. Type information may be demoted into a document only when the document is requested.
