Round Trip:

This is a measurement of the round-trip transit time for a retransmission request
packet sent by the decoder to be received by the source, plus the time for the
replacement packet to then travel from the source back to the QVDEC4K decoder.

The next section of the Dashboard shows the system uptime since it was powered up. followed by
the memory usage.

Lastly, the Dashboard shows the

Send

and

Receive

network usage for the two Ethernet ports. In

the example below, we see that GigE 2 is receiving an instantaneous value of 11.2 Mbps for the
4K stream that it is receiving.

Figure 4. Dashboard: Statistics, example showing the decoder receiving an ARQ 2160p stream on GigE 2.
