摘要： An optical disc drive includes a firmware memory, a buffer memory, and a system control chip. The system control chip includes a processor and a memory update controller. When the optical disc drive is under a normal mode, the memory update controller is in an idle state. The processor controls the optical disc drive to fetch an update firmware from an optical disc and store the update firmware into the buffer memory. When the optical disc drive is under a firmware update mode, the processor is in an idle state. The memory update controller fetches the update firmware from the buffer memory and stores the update firmware into the firmware memory without the processor executing an update routine code.

In step (a), a multiword information cluster, e.g., ECC, including high protective codewords, e.g., BIS, and low protective codewords, e.g., LDC, is provided. In step (b), the high and low protective codewords are stored into a first memory, e.g., DRAM.

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.
