5.4.1.5 Dual IP Input
The Dual IP input module allows two individual input interfaces to be connected to network sources, but for the
system, this is exactly as two IP input cards. The input streams can be either SPTS (VBR or CBR mode) or MPTS. to
configure the module.
All function and status normally associated with IP input cards are present for the module but the total Input Bitrate
for both IP ports cannot exceed 850 Mbps or 250 services, ie the limit is shared between the two ports.
An alarm (“Back-plane bitrate exceeded. Packet dropped.”) will be raised when the 850Mbps backplane limitation
is exceeded.
5.4.1.6 SRT IP Input
The Secure Reliable Transport (SRT) input is a new generation IP module. It's an open source video transport
protocol optimized for unreliable networks (packet loss, jitter, and fluctuating bandwidth), typically used for
transmissions over the Internet. End-to-end 128, 192 or 256 bit AES encryption is available. Different connection
modes are provided for easy firewall traversal.
An SRT input connection can be configured as three different modes:
It should be noted that in rendezvous mode, both the destination and source port will always be equal.
An SRT module will always use Port A as SRT Input, and Port B as SRT output. Each mode requires a specific
license.
An example of an end-to-end SRT connection can be as follow:
Port B IP: 10.10.10.123 Output: Mode: Listener Source port: 20000
Port A IP: 10.10.10.234 Input: Mode: Caller IP: 10.10.10.123 Source port: 20000 Destination port: 30000
