The default setting is "6.1 Mbps (150 ms)" for all
channels.
TOS BIT
It is necessary to set the TOS (Type of Service) bit to
control priorities of streaming data in a switching hub
or a router.
Note: Some models of switching hubs and routers
are not compatible with the TOS bit.
In this case, use the default settings for this item.
(There is no problem with any value for this
setting.) 
0 to 7 are available for the "TOS BIT". ("7" is the
highest priority.)
The default setting is "0" for all channels.
Refer to a network administrator about compatibility
of the switching hub or the router, and priority to be
selected for this item.
TTL
It is necessary to set the TTL (Time to Live) to not to
send streaming data to a network that does not want
it when using multicast transmission.
0 to 255 are available for the TTL.
The selected value is diminished one by one each
time the stream data passes the switching hub or the
router, and stops passing the switching hub or the
router when it reaches to 0.
The default setting is "16" for all channels.
ENCODER START UP SETUP
Select "START" or "STOP" whether the encoder
starts streaming video and audio data transmission
automatically or not after restarting or turning the
power of the encoder on.
The default setting is "START" for all channels.
CAMERA CABLE COMPENSATION
Select a cable length from "S", "M" or "L" depending
on the distance between the camera and the
encoder.
Select the proper cable length to obtain proper
pictures by amplifying the video signal effectively.
When using RG-59U, BELDEN 9259 or equivalent
cables, a cable length of "S", "M" and "L" will be
determined as follows;
S:Less than 400 m (1 300 ft)
M:400 m (1 300 ft) - less than 700 m (2 300 ft)
L:700 m (2 300 ft) - less than1 900 m (3 000ft)
The default setting is "S" for all channels.
DYNAMIC RANGE
Select a maximum brightness level of the camera
picture. When using a camera with high-level
brightness, select "WIDE" or "SUPER WIDE".
NORMAL:Normally, select this.
WIDE:Makes the maximum brightness level higher
than "NORMAL"
SUPER WIDE:Makes the maximum brightness level
higher than "WIDE"
The default setting is "NORMAL" for all channels.
WATERMARK
Watermark is the function which embeds data such
as time and date in video data.
When using a server to save and stock encoded
MPEG2 data with the encoder, it is useful to check
their authenticity.

camera and the decoder.
When "STRONG" is selected, the authenticity of the
watermark will be more reliable but the quality of
pictures will become lower.
The default setting is "OFF" for all channels.
GOP
In a MPEG stream, coded data is a composition of
frame units. This unit is called GOP (Group of
Picture). GOP consists of 3 picture groups (I picture,
P picture and B picture). The intervals between I-
frames become shorter when the GOP size is
smaller; the intervals between I-frames become
longer when the GOP size is bigger.
For example, when the GOP size is 15, an I-frame
will be inserted every 500ms and the rest of the 14
frames consist of P-frames.
The default setting is "15" for all channels.
