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.
