Method for improving the functions of the binary representation of mpeg-7 and other xml-based content descriptions |
摘要 |
The aim of the invention is to encode string-based data types, which have for example a tree-type structure, in such a way that signal bits (flags) for optional sections and/or for length information concerning the codes that are of variable length are placed in a defined sequence at the beginning of the created bitstream, thus accelerating the search for data by means of a sorting process and bit mask queries. The invention also relates to a more efficient encoding of the #position field by, among other things, the assignment of code fragments for each group of regular expressions.
