Using the Equipment
3.17.6.5
Functional Description
Multi Protocol Encapsulation (MPE) provides a method for IP datagrams to be
placed into DVB compliant Transport Streams using an MPE encapsulator. Upon
reception of the Transport Stream this "broadcast data" can then be returned to IP
data using an RX8000. This means a broadcaster can use their broadcast
infrastructure to send IP data transparently across a DVB link. This data is defined in
ISO-IEC 13818-6 / ETSI 301-192. The data is broadcast as private section
information on a particular PID. These sections are known as DSM-CC sections.
Each of these private sections contains an IP datagram.
IP datagrams are identified within the section by a MAC address field. Within the
MPE data PID there can be many IP datagrams with many different destinations.
Further filtering on the PID must be carried out using this MAC address. This MAC
address is also used to regenerate MAC frames for transmission on the output data
port (this becomes the destination MAC address).
The RX8000 supplies the recovered IP data to down-stream network equipment
using either one or both of its output data ports.

Setup: Decode > MPE
The output port configuration on the Output tab does not need to be used for this
functionality to work. All setup is carried out from the Decode > MPE sub-tab of the
web interface.

PID
The PID field provides the PID selection. The PIDs are automatically assigned when
a service is selected and is based on their order within the service PMT. This field
provides an opportunity for the user to override any PID selections.
