Codec-agnostic dynamic and distributed adaptation of scalable multimedia content

Today's Internet is accessible to diverse end devices through a wide variety of network types. Independent from this huge amount of usage contexts, content consumers desire to retrieve content with the best possible supported quality. The designers of new media codecs react to this diversity of usage contexts by including adaptation support into the codec design. Scalable media codecs, such as the new MPEG-4 Scalable Video Codec, enable to easily retrieve different qualities of the media content by simply disregarding certain media segments. All these variables (different end devices, network types, user preferences, media codec types, scalability options) lead to a manifold of needed and possible adaptation operations.
