Item Specification
Transport
streams/GbE
connection
256 incoming transport streams per connection. However,
the total number of transport streams able to be processed
via each data input is dependent upon the transport stream
bit rates.
Addresses
Each Ethernet interface has a unique MAC address, and IP
and MAC address pairs can entered or deleted manually or
via the control system. There is one output destination
address per TS per physical port.
Multicasting and Unicast addressing are supported.
Address Resolution Protocol (ARP) is supported but can be
disabled.
Input Format IP input is IPv4. Non-RTP and non-FEC input is supported.
Data rate
Maximum input data rate supported (sum of incoming
transport streams) on each GbE data interface is for UDP
952.24 Mbps and RTP 944.05 Mbps. The number of
supported transport streams packets per UDP/RTP frame is
1 to 7.
Output Format
The IP output is IPv4 and is encapsulated according to the
DVB IP Phase 1 Handbook (RTP encapsulation without
FEC), as a user-configurable option.
Non-RTP and non-FEC output is supported
The number of MPEG packets per TS are included in an IP
datagram for output can be specified. This is limited to a
maximum of seven TS packets per IP datagram.
Data rate
Maximum output data rate supported (sum of outgoing
transport streams) on each GbE data interface is UDP
formatted frames = 952.24 Mbps and RTP formatted frames
= 944.05 Mbps. The number of supported transport streams
packets per UDP/RTP frame is 1 to 7.
Uni/multicast
Each output transport stream may be sent to either a single
unicast or a single multicast address per physical port
Using RTP, without FEC, with 7 MPEG packets per frame is
944.05 Mbps.
Useful output data rate
– each output
(maximum - in the
absence of any other
network traffic)
Using UDP encapsulation, with 7 MPEG frame is 952.24
Mbps.
