bringing Video-on-demand (VoD)
to television which permits a
customer to browse an online
program or film catalog, to watch
trailers and to then select a
selected recording.

delays if the streamed data is unreliable.
IPTV has strict minimum speed
requirements in order to facilitate the
right number of frames per second to
deliver moving pictures. This means that
the limited connection speed/bandwidth
available for a large IPTV customer
base can reduce the service quality
delivered.
