paCket Loss graph
By selecting the Loss tab, you will see a graph that indicates, in percentage terms, what’s gone wrong on the
network during each one- second window. Three different color-coded entries appear here:
1 Packet Loss (dark red) - The system has detected a packet has been completely dropped by
the network and was never received by the decoder.
2 Packet Late (bright red) - The system received the packet, but it was too late for decoding and
playout.
3 Packet Recovered (green) - The packet was either lost or late, but was recovered either by the
Forward Error Correction (FEC) or Automatic Repeat Query (ARQ) error correction built into
CrossLock .
DeLay sLIDer
The most powerful way to stabilize any streaming connection is to have the decoder add a delay buffer to the
connection. This compensates for changes in the rate packets are received - known as jitter in Internet speak.
CrossLock uses a combination of decode delay buffering and error correction to keep connections stable. When
CrossLock is active, the activity of the delay buffer is illustrated and controlled via the delay slider on the Delay tab .
The slider above is in Auto Delay mode and the information on the slider is purely for informational purposes.
Clicking off the Auto Delay box sets the system to Manual Delay mode and allows the slider to be moved via the
touchscreen.
