1.3 Role of the ASI-IP-GTW in a Typical System

The ASI-IP-GTW provides a bridge between the MPEG-2 world and the
IP world. The unit provides an interface between MPEG-2 transport
streams, via DVB-ASI interface, to the IP based Network. It provides the
ability to carry up to 8 individual MPEG-2 transport streams over an IP
network. Each individual MPEG-2 transport stream is carried on an
individual UDP port. At the reception site, the unit de-concentrates the
MPEG-2 transport streams from the IP network, back to individual
MPEG-2 transport streams and out through the DVB-ASI connections.

Figure 2 provides an overview of the ASI-IP-GTW in transmit and
receive mode.
