De-jitter
The de-jitter setting configures the de-jitter configurations depending on the
type of input data.
DVB/MPEG inputs
OFF:
No de-jittering applied.
CBR->Bitrate:
Optional parameter-. If the input rate is known, setting this
parameter will cause the input chain be quicker to get the rate-control
accurate.
PCR->Preferred PID:
Optional parameter. If not set the unit will use one
which is signaled in the PMT.
RTP inputs
OFF:
No de-jittering applied.
RTP:
The RTP header is used for de-jittering. Note currently the timing
model supported is for 2022-6 content only. i.e. TS based sources cannot
be De-jittered using RTP mode.
De-jitter
Buffer(ms)
Both the MPEG/DVB and RTP inputs have a configurable input de-jitter
buffer. The default value of this buffer when not set is 100ms.
This buffer should be set to the jitter that needs to be compensated for,
allowing for an additional overhead.
In PCR dejitter mode the time should be set to at least twice the (PCR
in network jitter).
Seamless
input
When enabled the system is prepared to receive the same content via two
interfaces. The seamless input is linked to ports pairs. Both the 10G and
1G ports may be used with this mode.
Seamless mode:
Floating:
The seamless logic will change the source only when the
currently selected source is faulty.
Path 1:
The seamless logic will use input path1, if this source is not faulty
Path 2:
The seamless logic will use input path2, if this source is not faulty
Seamless buffer size:
Buffer size in milliseconds.
1->420 ms.
Buffer size assigned to the seamless input buffer logic. This buffer is in
before the dejitter buffer in the input chain.
Interface
Select the input interface. This list included the interfaces which are tagged
as RX enable in the interface configuration page.
IP / Port
The IP address and port of the incoming stream. This could be a multicast,
or a unicast. In the case of unicast, then use the IP address of the selected
interface.
IGMPV3
Source IP
In networks where PIM is not used, use this field to enter the source IP
address.
