button to restore the invalid entry to the value
before the change was made. If you press the
[Cancel] button, other changed items will also be
restored to the values before the change was
made.
0 There is upper limit to transmission bit rate from
the camera. If a bit rate that exceeds upper limit
is specified, this new setting will not be applied.
For details on the maximum transmission limit,
refer to the following.

The contents displayed in “Encoder No.1”,
“Encoder No.2” and “Encoder No.3“ change
depending on the type of encoding and the item
selected.

If the distribution bit rate exceeds 40 Mbps, the
specified frame rate distribution fails.
0
In cases such as high-bitrate distribution at a
frame size of 1920 ´ 1080 and frame rate of 30
fps (particularly slow pan operations), the
camera image may not appear smooth even on
a high-performance computer. In this case,
lower the [Framesize], [Framerate], and
[Bitrate], and check the image again.
Memo :
0
H.264 High indicates H.264 High Profile, and H.
264 Baseline indicates H.264 Baseline Profile.

video image displayed may be slightly disrupted
at the top edge.

Select a frame rate.
[Set values:
R
30 fps, 25 fps (JPEG is not
supported), 15 fps, 10 fps, 7.5 fps, 5 fps, 3 fps, 2
fps, 1 fps]
9 Bitrate (when “H.264 Baseline” or “H.264
High” is selected)
Select whether to set the scalable rate control
method for single encoding to CBR (Constant Bit
Rate) or VBR (Variable Bit Rate).
0
CBR:
Data is encoded at a fixed bit rate regardless of
the condition of input video signals. It is easy to
estimate the bit rate. Select from the list of bit
rate ranges.
