Abstract:
1. A computerized method for generating an index of Data Units of a Variable Length Coded (VLC) image, said method comprising: categorizing Data Unit lengths, DU-lengths, as non-indexed DU-lengths, categorizing DU-lengths not categorized as non-indexed DU-lengths as indexed DU-lengths, generating by a processor a value indicating the number of subsequent DU-lengths categorized as non-indexed in a sequence of subsequent DU-lengths categorized as non-indexed, generating a value indicating the number of subsequent DU-lengths categorized as indexed in a sequence of subsequent DU-lengths categorized as indexed, generating data representing the DU-length of each DU in the sequence of DU-lengths categorized as indexed, storing said generated values and data in the index of Data Units, and associating said index of Data Units with the VLC image.
