A Encode

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-Encode1,

 

 

 

 

Multi-Encode2]

 

 

 

 

 

Single-Encode

[Set values: JPEG, H.264 Baseline, H.264 High]

 

 

 

 

Multi-Resolution

[Set values: JPEG, H.264 Baseline, H.264 High]

 

 

 

 

Multi-Encode1

[Set values: JPEG + H.264 Baseline, JPEG + H.264 High]

 

 

 

 

Multi-Encode2

[Set values: JPEG(1280x960) + MPEG4(640x480)

 

 

 

 

JPEG(1280x960) + MPEG4(320x240)

 

 

 

 

JPEG(640x480) + MPEG4(640x480)

 

 

 

 

JPEG(320x240) + MPEG4(320x240)]

 

 

 

 

B Aspect Ratio

Selects the width:height ratio of the image.

 

 

 

[Set values: 16:9, 4:3]

 

 

C Single-Encode

Enables Encoder No.1 only out of three channels of encoders. You can

 

 

 

set a frame rate that exceeds 5 fps.

 

 

 

 

 

Encoder

Framesize

Select the frame size of each JPEG or H.264 screen.

 

No.1

 

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]

 

 

 

 

 

 

Framerate

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]

 

 

 

 

 

 

Bitrate

Select whether to set the control rate mode for single encoding to CBR

 

 

(Rate

(Constant Bit Rate) or VBR (Variable Bit Rate).

: Data is encoded at a fixed bit rate regardless of the

 

 

mode)

 

 

 

 

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.

I Frame

Select the I-frame interval. Encoding starts from the I-frame. Shortening

 

 

Interval

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.
