Multimedia across Residential Networks.
The multi-megabit connections offered by cable modems and residential networks
should enable interactive multimedia applications to be brought to the home. ANSPAG
plans to conduct video on demand trials with a number of sites in Victoria, the
aim being to determine the feasibility of current systems to provide video on demand
via cable networks that will be the candidate for a commercial VOD service network
in the not too distant future. The trial has been planned to use a bi-directional
10Mbit/s (in each direction) coaxial link to connect the video server at ANSPAG
to a cable network. The customer sites involved will be provided with a coaxial
drop that is connected from network tap to a network interface unit. Signals for
digital data and analogue TV is split at the network interface unit, and is then
fed to wall mounted plates via coaxial cables. Cable TV codecs and cable modems
can be directly plugged into the connectors on these walls mounted plates. There
will also be a PC client running in the ANSPAG laboratory through a second cable
modem also installed at Monash University (Figure 0-12).
Currently, there are two 2Mbit/s links between the cable network and Monash University
via cable modems, allowing Monash to experiment with delivery of multimedia across
a residential network.
