Packet Protection Mode
With Packet Protection Mode, the PIPM-R-7 will accept signals from both Media LAN 1 and Media
LAN 2, allowing for hitless media switching in the event that one of the signals is interrupted.
Single Stream - When set to Single Stream, the PIPM-R-7 will accept one signal from Media
LAN 1 only. If packets are out of order, they will be rearranged into the correct order. Note that
hitless protection is not part of Single Stream mode.
Dual Stream - When set to Dual Stream, hitless media protection is enabled. Two identical
copies of the same stream are accepted from Media LAN 1 and Media LAN 2. Both streams are
compared packet by packet. If one stream is missing a packet, it will be taken from the other
stream to make sure that one good stream comes through properly.
Bypass - When set to Bypass, the PIPM-R-7 takes the media stream from Media
LAN 1. The stream bypasses the entire hitless protection block.
Hitless Window Size (ms)
NOTE: Applicable only if Hitless Media Support is enabled.
Set the amount of time in milliseconds that the unit will look for redundant packets to decide to
accept or reject them for hitless media switching.
To determine the hitless window size, consider any delay between the signals, expected jitter,
along with any other sources of potential delay between signals.
Possible values range from 1 to 50. The actual range is determined by the signal's frame rate,
raster size and other factors.
Frame Sync Mode
Frame Sync Mode can be enabled for synchronizing frames to the timing source you are using.
Enable - Frame Sync Mode is enabled.
Bypass - Frame Sync Mode is disabled.
Audio Rate Converter Mode
In cases where there are either missing audio packets or the audio clock is not synchronous with
the timing source, the audio rate converter can match the output audio rate to the local clock.
Select either of the following options:
• Use Audio Src
• Bypass Audio Src
Input Stream Selection
Select Manual, SDP or NMOS/Ember
