Media Adaptation

Introduction

The basic concept behind dynamic media adaptation is the modification of high-quality media content, according to a variety of contexts or constraints (devices, networks, user preferences, mobility, etc), in order to provide a "guaranteed user experience" in a dynamic and real-time environment.

The concept of media adaptation has been present in research activities in various key forms for many years: transcoding (the conversion of media encodings, e.g. MPEG1 to MPEG2) and transmoding (the conversion of media types, e.g. graphics to video) are well established technologies both in software and hardware; methodologies using Quality of Service (QoS) have established a media adaptation basis for networks; and the editing media for different formats and audiences (everything from Cinema, in-flight movies, to the pre-9 o'clock watershed on television) has been until now an arduous and manual process performed to cover a wide audience; all represent various forms of media adaptation. Dynamic Media Adaptation aims to change all that by encompassing these technologies and more into a real-time streaming environment and adapting media directly for each individual user’s requirements
