the loss arrives at the codec. Setting the Max Burst Drop Delay (in milliseconds) will delay the ARQ
repeat request by this amount to handle packet burst losses.
Robust Mode:
Normally, the ARQ will only require that a minimum of one repeat request is sent to
the video encoding source device, regardless of the Target Latency. However, enabling Robust
Mode will increase the minimum number of repeat requests to a minimum of two retries.
ARQ Port:
By default, ARQ normally sends upstream retransmission request packets on UDP port
7020. You can change this ARQ Port setting to any valid and non-conflicting UDP port. However,
you must make certain that you specify the same port number at both the encoder and the
decoder.
