This discussion of the capabilities of UPnP has hopefully highlighted a
third paradigm: a remote with its own UI that controls a single other
device via the home network.
For example: The remote is a tablet or laptop showing a web based
presentation. The TV or STB is showing a programme. The TV/STB is sourcing
the programme from live broadcast, or playing it back from an internal
hard drive (a PVR style device) or streaming it from an internet video on
demand service. The presentation content tracks the progress of playback
and changes between sets of slides to suit the particular part of the
programme. The web based presentation also allows the user to choose a
particular part of the programme and jump to it (if the programme is not
coming from a live broadcast of course!)
The experiment we have done at the BBC involving one of our programmes -
"AutumnWatch" is a concrete example of this. We have extended this
experiment to the PVR scenario.
