Click on the icon on the bottom right of the page to add IP destinations.
Click on “Save” to confirm the settings. Click on “Save & New” to confirm the settings and create a new IP service
with the same parameters.
Click on “Close” to discard the settings.
Log traces associated to an IP service
To view the log traces associated with an IP service, click on its status LED on the right, as shown on the screen capture
below.
Network interface/VLAN Read/Write Select the network interface or bond or VLAN for this stream.
In case the target address is unicast, select “Any” so that the Eth interface is determined
automatically according to this IP address, or select a VLAN.
In case the target IP address is multicast, select the Eth interface or the VLAN.
Local source port Read/Write Local UDP port number of IQOYA X/LINK
DSCP Read/Write Select the quality of service (QoS) class of the stream.
FEC stream MPEG
This section allows configuring a Pro MPEG COP#3.2 FEC for the MPEG-TS stream.
Type Read/Write No Redundancy : No FEC is generated.
Column : 1 dimension FEC scheme. Only FEC frames generated from columns are
streamed. Number of columns can be set from 1 to 20. This FEC is ideal for correcting
packet burst errors and random errors. The column FEC frames are sent to UDP port =
MPEG-TS stream UDP port + 2.
Column and row : 2 dimensions FEC scheme. Provides correction for non-consecutive lost
frames, and can correct any single packet loss within a row of media packets.
● 4 <= Number of Columns (L) <= 20.
● 4 <= Number of rows (D) <= 20
● L x D <= 100
The column FEC frames are sent to UDP port = MPEG-TS stream UDP port + 2.
The row FEC frames are sent to UDP port = MPEG-TS stream UDP port + 4.
Number of columns (L) Read/Write Column depth
Column scheme: value from 1 to 20
Column and row scheme: 4 <= L <= 20
Number of rows (D) Read/Write Row depth: 4 <= Number of rows (D) <= 20
