Robust Mode is enabled, it sets a minimum ARQ latency of one round-trip time. A larger Target Latency
allows the system to increase the number or repeat requests.
Max Burst Drop: A Burst Drop delay can also be specified to delay any retransmission requests for a time
equal to the maximum expected packet loss time, such as from dynamic router changes of other sources
of burst loss.
Multi-Retransmit Mode: This parameter allows the user to enable or disable RX side Proxy ARQ Auto
Mode Robust Mode. This gives high performance for stream recovery with the tradeoff of more latency.
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.
5.4.4. Monitoring
Name: This parameter displays the RX side IP Stream Name.
Running: This parameter returns whether the RX side IP Stream is running or not: Yes or No.
5.4.5. Network Status
Sender IP: This parameter returns the RX side IP Stream Network Sender IP. For example this could be
the IP address of the sending 7890IXG-T.
Port: This parameter returns the RX side IP Stream Network port number.
Bit Rate: This parameter returns the RX side IP Stream Network bit rate.
Packet Loss: This parameter returns the RX side IP Stream Network packet loss.
Jitter: This parameter returns the RX side IP Stream Network jitter. Packets in incoming IP packet
streams may lose their ordering or suffer variable delays during transport through an IP network. The
proxy receiver buffers all incoming video/IP packets in a buffer and reorders RTP encapsulated packets by
RTP sequence number. This parameter specifies the size of this incoming packet buffer in milliseconds of
delay. Specify 0 here to disable this additional buffering when latency needs to be minimize.
Dropped: This parameter returns the RX side IP Stream Network drops.
Total Packets: This parameter returns the RX side IP Stream Network total packets.
5.4.6. ARQ Status
Unrecovered: This parameter returns the number of RX side IP Stream ARQ unrecovered packets.
Recovered: This parameter returns the number of RX side IP Stream ARQ recovered packets.
Max Burst Loss Packets: This parameter returns the number of RX side IP Stream ARQ max burst loss
packets.
Port: This parameter returns the RX side IP Stream ARQ port number.
