An apparatus for switching between a first network and a second network comprises a generator, a processor and a switch. The generator generates a table, wherein the table stores first connection information for the first network and second connection information for the second network. The processor checks a status of the first network in response to the first connection information. The switch selects the second network to communicate in response to the second connection information if the status indicates that the first network is not available. A method for switching between a first network and a second network comprises: generating a table, wherein the table stores first connection information for the first network and second connection information for the second network; checking a status of the first network in response to the first connection information; and selecting the second network to communicate in response to the second connection information if the status indicates that the first network is not available.

A check system and method for checking EDC of a DVD sector without prior descrambling the sector. In the EDC check method, after the sector is received, a check value corresponding to a sector identification (ID) of the sector is generated. Meanwhile, an EDC value of the sector is calculated directly without prior descrambling the sector. Finally, the EDC value and the check value are compared. If the EDC value equals to the check value, a sector-correct signal is outputted; otherwise, a sector-error signal is outputted. Because the EDC check method and system of the invention skip the prior data descrambling step, the processing speed can be improved and the hardware resources may be more-efficiently used.

A controller circuitry for CD-ROM drive used for the storage of digital data, capable of reading data store on the CD-ROM disc and decoding to transfer the decoded data into the host computer system via an interface bus. Under the ISO 9660 standard, the controller circuitry includes a CIRC processor and an RSPC/EDC processor combined with a bus interface controller, each of which is capable of accessing a working memory device tied together. The combined circuitry configuration allows reduced access frequency in the working memory device, and there is no need to use internal high-speed SRAM. The entire controller circuitry may be fabricated as one single IC device to reduce cost while performance is improved.
