Ambient networks: an architecture for communication networks beyond 3G

this paper. 5.1 Ambient Media Delivery Overlay Media distribution and delivery is foreseen to become an important task within Ambient Networks. Multimedia services have different requirements when it comes to required media delivery support functions (e.g. conversational multimedia, download, messaging, streaming, multicast/broadcast). Synergies can only be expected from providing a common media delivery support layer to all kind of multimedia services. However, this media delivery layer needs to fulfil all requirements posed by existing multimedia services and it needs to be extendable in order to cope with future service requirements. A particular challenge is the support of "ambient" multimedia services, integrating different end-devices and various access technologies in a seamless way for the sake of an increased service performance and end-user convenience
