The Missing Packet statistics counters have a higher order of precedence than the Out-of-Range statistic
counter.
These are the conditions for a packet to be considered as missing from an IP Receiver Stream (video,
audio, or ANC):
•
if both Ethernet ports are present, it has to be missing on both Primary and Secondary ports
•
if only the Primary Ethernet port is connected, it is missing from the Primary port
•
if only the Secondary Ethernet port is connected, it is missing from the Secondary port
A missing packet’s time label exceeds not only the Playout Delay value (the Receiver’s programmable
buffer depth) but also the physical hardware buffer size.
All RTP packets are written into the Receiver’s
buffer and marked with a time label, which is derived from the local PTP clock. Under normal
operations, packets read from the Receiver’s buffer will have a time l
abel which is less than the physical
hardware buffer size.
If a packet is read from memory and it has an old time label, then it’s considered
to be missing.
The Out-of-Range statistic counter increments when the time label exceeds the Playout Delay value plus
some margin of error.

ST 2022-6 (only available when the standard is HD)
Note:
When in 2022-6 mode, due to a bandwidth routing limitation, you
should not configure more than six channels in a Processor to receive at
1080p/50 or 1080p/59, or the switch mode will revert to Make After Break
mode resulting in non-clean switches.
2022-6 Mode Audio Source
This parameter appears when the Receiver mode (above) is ST 2022-6
only. Options are:
