"Forward Error Correction (FEC)" is set to
"On", you cannot set "Lip Sync" to "Off" in
the Audio setup menu.
QoS1
Basic Setup
Adaptive Rate Control (ARC)
Allows you to select whether to always
optimize the LAN bandwidth.
On: Always optimizes the LAN bandwidth.
Off: Does not optimize the LAN bandwidth.
Auto Bandwidth Detection
Allows you to select whether you use the
Auto Bandwidth Detection feature.
On: Enables the Auto Bandwidth Detection
feature.
Off: Disables the Auto Bandwidth Detection
feature.
TCP Port Number
Enter the fixed TCP port number.
UDP Port Number
Enter the fixed UDP port number.
For details on the port numbers used on the
system, see "List of Port Numbers Used on
the PCS-XG80/XG80S" on page 243.
Packet Resend Request (ARQ)
Allows you to select whether to request
packet to be resent when packet losses occur
during communication.
On: Requests packets to be resent.
Off: Does not request packets to be resent.
ARQ Buffering Time
Set the buffering time used for "Packet
Resend Request".
You can select from among "300ms",
"150ms", "80ms", "Auto" and "Custom".
When "Custom" is selected, you can specify
any buffering time.
ARQ Buffering Time
Enter the buffering time (50 ms to 999 ms)
when you select "Custom" in "ARQ
Buffering Time".

Registering Local Information
Forward Error Correction (FEC)
Allows you to select whether received
packets are identified with an error
correction mark.
On: Identifies with an error correction mark.
Off: Not identify with an error correction
mark.
FEC Redundancy
Allows you to set redundancy of the packet
used for the Forward Error Correction
(FEC).
You can select from among "8", "4", "2" and
"Auto". When you select "8", "4" and "2",
the communication bit rate may be different
from the specified value.
Audio Duplex Transmission
Allows you to select whether to
automatically transmit audio in double when
audio communication is interrupted
depending on a network status.
On: Enables the Audio Duplex
Transmission feature.
Off: Disables the Audio Duplex
Transmission feature.
QoS2
Re-Order/Shaping
Re-Order
Allows you to select whether to correct re-
order that may cause packet loss (invalid
order of arrival in the packet). Correcting re-
order enables smoother picture and sound.
On: Corrects re-order.
Off: Does not correct re-order.
Re-Order Buffer
Allows you to select re-order buffer.
You can select from among "Auto", "1",
"2" and "Custom".
Re-Order Buffer Rate
Enter the re-order buffer rate. You can enter
the value between 1 and 5.
Shaping
Allows you to select whether to use shaping,
which adjusts the IP packet transfer rate.
On: Uses shaping.
Off: Does not use shaping.
