Bandwidth Used

The Bandwidth Used section provides a graphical overview of how the network bandwidth available to the SRT stream is actually being used, in terms of the rate at which packets are sent, received, resent and lost, as well as the data volume (rate × time).

Makito X4 Encoder (SRT source device)

Makito X4 Decoder (SRT destination device)

SrcDestParameterDescription

Send RateCheck this box to view a plot of the SRT source device’s outbound bitrate over time (green line in the graph).

Receive RateCheck this box to view a plot of the SRT destination device’s inbound bitrate over time (green line in the graph).

Retransmit RateCheck this box to view a plot of the rate at which the SRT source device is resending packets (yellow line in the graph).

Lost RateCheck this box to view a plot of the rate at which SRT source device is reporting lost packets (yellow line in the graph).
Link BandwidthCheck this box to view a plot of bandwidth available to the SRT stream (blue line in the graph). This is a plot of the Link Bandwidth (or equivalent Max Path Bandwidth on the source device) shown in the SRT panel.

What to look for:

  • The use of encryption has an impact on the processing resources of the source device, which may have an effect on streaming capacity overall.
  • If the SRT destination device shows too many skipped or dropped frames, increase the SRT Latency, lower the video bit rate, and/or increase the Bandwidth Overhead %.
