Abstract:
A digital communication apparatus for transmitting sectors of digital units, each sector comprising a series of blocks and each block including error correction values used to detect and correct errors within the block, the error correction values useful in correcting up to a maximum number of digital units, the digital communication apparatus comprising:an encoding system, for producing an encoded series of digital values from the blocks of digital units, the encoded series of digital values comprising sections of interleaved codewords, each codeword in each section separately encoded from other codewords in the section, the codewords of a section together encoded form a set of digital units, the set of digital units including one digital unit from each block in the sector;a channel coupled to the encoding system to receive the encoded series of digital values and to produce a representation of the encoded series, the channel capable of occasionally introducing burst errors into the representation of the encoded series; anda decoding system, coupled to the channel to produce a representation of the blocks of digital units received by the encoding system, the decoding system's representation based on the channel's representation of the encoded series.
