A mechanism for presentation-layer media continuity in media playback mode

ABSTRACT

This demo presents a new approach for media presentation continuity in playback mode. We use the term presentation continuity over session transfer since our solution is at the presentation layer. Previous research on this topic has focused on transferring a particular stream or set of related streams at the sessions layer. Our approach presents an alternative, recognising the fact that a user is connected to a media presentation, which, may be composed of multiple sessions. The advantages of our approach are i) Lower network control plane overhead, thus reducing chances of semantic presentation loss ii) Lower network data overhead due to lesser need for transcoding iii) delegating presentation semantic issues, such as inter-media synchronisation, to the player iv) dynamically adapt the presentation to the new target devices without transcoding.
