System, method and computer readable medium for compressing a data sequence for partial decompressing |
摘要 |
A method for compressing an input sequence of data portions to produce an output codestream and for partially decompressing the output codestream to obtain a selected segment of the input sequence is disclosed. The output codestream includes a sequence of non-matchable sequences and codewords. The codewords include a first codeword and subsequent codewords. Each of the codewords includes at least a length of a subsequent non-matchable sequence preceding a matchable first sequence. Each of the subsequent codewords further includes a first offset for indicating a start of the matchable first sequence in the preceding non-matchable sequence, a length of the matchable first sequence and a second offset for indicating a location of a preceding codeword in the output codestream. A program storage device and a compressing/decompressing system for providing the above method are also disclosed.
