METHOD FOR IMPROVING FUNCTIONALITY OF BINARY REPRESENTATION OF MPEG-7 AND OTHER XML-BASED CONTENT DESCRIPTION

摘要

PPROBLEM TO BE SOLVED: To allow extensions to an instanced document which is not contained in individual schema template to be effected with the least possible effort by reducing a data amount to be transmitted, and simplifying search processes within the document, for improving the functionality of the binary representations of XML-based content descriptions. PSOLUTION: A structure of an instanced XML document corresponds to a tree-like data structure, and each tree node represents an element of the content description and has a structure which is defined in a schema. A decoder skips over paths containing unknown elements, the number of bits of a tree structure located at the back of individual elements and its content are transmitted, the decoder transmits a unique synchronization sequence after transmission of paths for skipping over the number of bits or containing new elements, and the decoder is restarted for the first time after reaching a tree node belonging to the known schema.
