Abstract

The Intelligent Personal Communication Support System is introduced as an application for multiple media conversion tools, embedded in a context of personal mobility, service personalization and service interoperability support. After discussing models for conversion in theory, the current conversion technology is evaluated. The necessity of an integrated framework of flexible converters and a generic converter model are derived and automatic management of conversion quality is discussed.
