Abstract
An apparatus for selectively rebuffering at least a portion of a data block read from an optical storage medium. The apparatus comprises a storage device for buffering the data block, and a rebuffering control module for rebuffering a specific portion into the storage device according to a previous decoding result, and thereby updating the buffered data block.
Claims26
An apparatus for selectively rebuffering at least a portion of a data block read from an optical storage medium, comprising:
- a storage device for buffering the data block for decoding;
- and
- a rebuffering control module coupled to the storage device for determining a specific portion of the data block requiring of rebuffering based on previous decoding, and rebuffering the specific portion into the storage device thereby updating the buffered data block.
A method for selectively rebuffering at least a portion of a data block read from an optical storage medium, comprising:
- (a) buffering the data block for decoding;
- (b) determining a specific portion of the data block requiring of rebuffering based on previous decoding;
- and
- (c) rebuffering the specific portion thereby updating the buffered data block.
An apparatus for decoding a data block composed of portions read from an optical storage medium, comprising:
- a storage device for orderly storing a first buffered data and a second buffered data through buffering the same data block read from the optical storage medium at different times, wherein the first buffered data is not overwritten by the second buffered data;
- and
- a decoding module coupled to the storage device, comprising:
- a storage unit for storing a parameter for indicating whether each portion or at least a portion of the first buffered data is correctly decoded;
- and
- a decoder coupled to the storage unit for decoding the data block utilizing the first and second buffered data according to the parameter.

- (a) orderly storing a first buffered data and a second buffered data through buffering the same data block read from the optical storage medium, wherein the first buffered data is not overwritten by the second buffered data;
- (b) determining a parameter for indicating whether each portion or at least a portions of the first buffered data is correctly decoded;
- and
- (c) decoding the data block utilizing the first and second buffered data according to the parameter.
