Select the encoding from [Single Encode], [Multi Resolution] or [Multi-
Encode].
C options vary depending on the selected encoding system.
[Set values: Single Encode, Multi Resolution, Multi Encode]
[Set values: JPEG, H.264 Baseline, H.264 High]
[Set values: JPEG, H.264 Baseline, H.264 High]
[Set values: JPEG+H.264 Baseline, JPEG+H.264 High]
[Set values: JPEG(1280 x 960) + MPEG-4(640 x 480)
JPEG(1280 x 960) + MPEG-4(320 x 240)
JPEG(640 x 480) + MPEG-4(640 x 480)
JPEG(320 x 240) + MPEG-4(320 x 240)]
Selects the width:height ratio of the image.
[Set values: 16:9, 4:3]
Enables Encode No. 1 only out of three channels of encoders. You can
set a frame rate that exceeds 5 fps.
Select the frame size of each JPEG or H.264 screen.
Available sizes vary depending on the aspect ratio.
[Set values for aspect ratio 16:9: 1920x1080, 1280x720, 640x360]
[Set values for aspect ratio 4:3: 1280x960, 640x480, 320x240]
Select a frame rate.
[Set values: 30 fps (this cannot be set for JPEG if the frame size is 1920
x 1080), 25 fps (JPEG is not supported), 15 fps, 10 fps, 7.5
fps, 5 fps, 3 fps, 2 fps, 1 fps]
Select whether to set the control rate mode for single encoding to CBR
(Constant Bit Rate) or VBR (Variable Bit Rate).
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.
VBR : The bit rate varies according to the condition of input video
signals. The picture quality is stabled but it is difficult to
estimate the bit rate. Select from the list of bit rate ranges.
[Set values: CBR, VBR]
Bit rate range
[Set values: 64 kbps, 128 kbps, 256 kbps, 384 kbps, 512 kbps,
768 kbps, 1024 kbps, 1536 kbps, 2048 kbps, 3072 kbps,
3584 kbps, 4096 kbps, 8192 kbps]
Select the I-frame interval. Encoding starts from the I-frame. Shortening
the interval stabilizes the picture quality even when there area rapid
changes in the video image. However, the picture quality for images with
little change will deteriorate. In addition, when multicast packet loss
occurs, the time interval required to restore the image is shorter.
[Set values: 5, 10, 15, 30, 60, 90, 120]
* The [Set values] in bold letters are factory defaults.
