Document Type and Number:
WIPO Patent Application WO2003007614
Kind Code:
A3
Abstract:
The invention regards a method for compressing a hierarchical tree describing a multimedia signal, said tree comprising nodes and leaves, which can be associated to contents of at least two distinct types.According to the invention, said method implements a content compression for at least some of said leaves by means of at least two compression encoding techniques, each of said techniques being selectively associated to at least one of said content types.
