초록 ▼

Digital data, in the form of blocks delimited by end-of-block words, that is to be coded into variable length codewords, is protected against errors occurring within a block, as well as errors crossing block boundaries, by modulating the respective end-of-block words with a bit, or bits, of a larger reference pattern which bit, or bits, have been conditioned to carry information on the content of VLC codewords coding a corresponding (eg. preceding) data block. The “modulation”may be by means of selecting between different possible end-of-block words dependent upon the value of the conditioned reference pattern bit, or bits, or by means of appending the conditioned bit(s) to the end-of-block word. The reference pattern may be a repeated pseudo-random sequence.

대표청구항 ▼

Method for error protecting a digital bitstream, the digital bitstream comprising a plurality of variable length codewords (VLC), coding blocks of digital data, said blocks of data being delimited by end-of-block words (EOB), the method comprising: generating bits of a reference pattern; modulating respective (EOB) by single, or small groups of, bits of the reference pattern, said single, or small groups of, reference pattern bits comprising only a portion of the reference pattern; the step of conditioning the single, or small group of, reference pattern bits modulating an (EOB) such that the conditioned bit, or bits, carry information relating to the VLC code words coding a corresponding data block; and wherein there are a plurality of available (EOB) and said step of modulating selects one of the available EOB words for use based on the value of the respective conditioned reference pattern bit, or bits.
