Configuring the XIP - 3901 - GB - IP Application with iControl
Redundancy Tab
Redundancy Tab
This tab allows you to view the reception state regarding SMPTE ST 2022-7 redundancy. The
primary and secondary streams, at the packet level, will work together in order to produce a
valid resulting stream. To achieve redundancy, both streams need to be in range with
respect to the receiver buffer. In the circumstance in which only one stream is successfully
received, the resulting stream will be valid as well but without any active redundancy
protection.
The XIP
- 3901 - GB - IP’s Receivers Panel, Redundancy tab configuration is the same as the
XIP - 3901 - UDC - IP’s IP’s Receivers Panel, Redundancy tab configuration; see Redundancy
Tab , on page 128.
Senders Panel
The Senders panel has three tabs ( GB1 , GB2 , and Advanced ); GB1 and GB2 are for each of
XIP - 3901 - GB - IP’s independent processing UHD channels. The
Advanced
tab allows you to
configure the outgoing payload type and DSCP priority.
Property Description
Media Shows the stream type. The background shows the current media status:
Green: No error
Red: Error
Grey:
Inactive
Stream Shows the primary (ETH1) and secondary (ETH2) stream receiver status:
Green: No error
Red: Error
Grey:
Inactive
Link Latency Shows the time it takes for a packet to come from the source to the receiver. This
measurement represents the difference between incoming RTP timestamp and PTP time
before the receiver's buffer.
Buffer level Shows the amount of preloaded data stored in the receiver that is ready for use in
microseconds and in percentage. The current buffer level in microseconds shows the
minimum latency required to receive a continuous stream. The current buffer level in
percentage shows how much of the internal buffering is used to receive the current
stream.
Link Offset Shows the resulting link latency after being read out from receiver's buffer.
This measurement is the difference between the packet RTP timestamp and the PTP time
after the receiver's buffer and represents the total reception delay.
Syntonized
Audio 1 to 4
Set to ignore Audio RTP timestamps. Audio buffer reception is then fixed to 25%. Use
these settings to manage audio streams that are not properly time stamped. Enable
syntonize for audio 1 to 4 individually.
