NODESTER

Video

Issue
Video connection
taking excessively long
to establish, or won't
establish.
Video connection will
not draw between two
video devices.
Video is excessively
delayed.
HTG-TEC-GUI-009_0
Release Mar 2021
Cause
Network traffic in one direction is
being blocked or is not available.
The device has too many
connections, or is not
compatible.
Latency is induced in the video
system, to enable packet re-
transmission in the event
forward error correction fails.
Resolution
Disconnect the devices via Nodester.
If the connection is between a Nodestream
decoder and a Nodestream encoder, open the
decoder connection controls.
If the device is a Wearwolf, open the video settings
In both cases, lower the bitrate to 1/4 of the
known network bandwidth. (If unsure, set to
128Kb/s). Increase the latency to 3 seconds
(3000ms). Reconnect the devices. If a connection
is achieved, increase the bitrate to the desired
value. If at any point grey screen / artfacts begin
to appear, the network link cannot sustain the set
bitrate. Lower the bitrate until the video is stable.
If this fails to rectify the problem, check the
network settings on both devices. Contact your
network administrator to confirm firewall settings
are not preventing a connection.
If the device connection limit is reached,
no further connections will be allowed.
At a proven bitrate, lower the device latency
(connection controls for decoders when
connecting encoders, or "Infinity settings" when
connecting to Infinity Wearwolf) to the desired
latency. If video errors begin to occur, the network
is not capable of sustaining streaming video at
this setting. Increase the latency until stable video
is achieved.
