The invention relates to the processor for performing convolution interleaving/de-interleaving on data symbols on plural original data symbols and convolution de-interleaving on the convolution interleaved data symbols. The processor for performing convolution interleaving on data symbol comprises a memory, an original address generator, and a storage address generator which generates an original address. The storage address generator generates the storage address of each of the stored plural data symbols in the memory according to the original address and a first predetermined sequence, and each of the convolution interleaved data symbols is stored in the memory according to the storage address; furthermore, all stored data symbols in the memory are configured into a circular structure.

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.

An apparatus for accessing DVD data is provided. In the apparatus for accessing the data of a DVD, a row data buffer and an error detection code file are added. The row data buffer stores the row data from the row data interface, and the error detection code file records the error detection code stored in the memory. When an error occurs in the error detection code, the error detection code in the error detection code file may be modified. In addition to the normal data access, the method of accessing DVD data only re-access when a certain error occurs during RSPC decoding.
