De-fragmentation of transmission sequences

摘要

The present invention aims at avoiding fragmentation during transmission of a structured document (10). This is achieved by a method of progressive transmission for a structured document (10), the structured document (10) comprising sub-documents (12, 14, 16, . . . ) with related relevance weightings. In particular, a fragmentation measure is determined according to the transmission sequence in an automatic manner using a formal expression of fragmentation. After comparison the fragmentation measure with a predetermined threshold value the transmission sequence is modified to reduce fragmentation when the fragmentation measure exceeds the threshold value.
