The end-user has a termi

35、nal that is able to request a media stream, either from a built-in player, or an installed application. The terminal can be any terminal with streaming media playing capabilities, and the service should allow a user to transfer between his terminals. The basic scenario is where an individual is brow

36、sing the Internet and finds some interesting content that he/she wants to watch. The end-user is then either doing this through the operators portal or accesses the content providers site. In the first case, the request is then processed through the portal, and charged as the stream is set-up. In th

37、e second case, the content provider redirects the request to the operator, so that the terminal capabilities can be collected and charging is done, before the stream is started. One scenario is an individual watching his favourite sports stream on his TV or PC at home, but he/she must leave the hous

38、e of some reason, and still wants to continue the session on his mobile terminal. In that case he/she would transfer the ongoing session to the other terminal with other capabilities, since he already paid for the entire episode. The other way is a similar case where an individual arrives at a desti

39、nation with better viewing capabilities. 4.1 Overview The figure below shows streaming content delivered to mobile terminals, but is not restricted to any particular terminal type. The content is either on a location accessible over the Internet or stored locally on an operators domain or the conten

40、t providers domain. The access to the content is done through a smart router controlling the stream towards the terminal. Transcoding of a stream is an optional feature that could allow users to switch between different terminal and networks, while consuming content from a streaming source. ETSI ETS
