D JPEG

Frame Size

For specifying the JPEG picture quality (rate control mode) and size

 

(target file size). When AVFS1B to AVFS7B is selected, the quantization

 

table during JPEG encoding will be maintained and the file size will

 

increase/decrease according to the input signals.

 

Typical sizes will be displayed in the Size field. When recording JPEG

 

data to a recorder with a limited storage capacity, the maximum

 

recording time may vary as the file size fluctuates under this setting.

 

When AAFSBis selected, encoding is performed such that the target file

 

size is the average size of multiple JPEG images.

 

You can enter the target size in the Size field.

 

[Picture quality values : VFS1 to VFS7, AFS]

Memo:

● The picture size can be specified only when the picture quality value is set to AFS.

[Size setting range in Quad VGA mode:40 KB to 200 KB ] [Size setting range in VGA mode:10 KB to 100 KB ] [Size setting range in QVGA mode:3 KB to 33 KB ]

E MPEG4

 

Bitrate

For setting the MPEG4 encoding bit rate.

 

 

[Set values : 64 kbps to 8000 kbps]

 

 

 

 

Bitrate Control

For selecting whether to set the MPEG4 rate control mode to CBR

 

 

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

 

 

CBR

: Encoding is performed at a fixed bit rate regardless of the

 

 

 

condition of the input video signals. Enables easy forecast of the

 

 

 

bit rate.

 

 

VBR

: Changes the bit rate according to the condition of the input video

 

 

 

signals. Picture quality is stable, but forecast of the bit rate is

 

 

 

difficult.

 

 

 

 

FPS

For setting the MPEG4 frame rate.

 

 

[Set values : 1 fps, 7.5 fps, 10 fps, 15 fps]

 

 

 

 

I Frame Interval

For setting the I-frame interval. MPEG4 starts encoding from the I-

 

 

frame.Shortening the interval stabilizes the picture quality even when

 

 

there are 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 : 15, 30, 45, 60, 75]

 

 

 

 

Priority

For selecting whether to assign priority to the frame rate or picture

 

 

quality during MPEG4 encoding.

 

 

FPS

: Assigns priority to frame rate. Select this setting to enable

 

 

 

smooth monitoring of motion images.

 

 

Quality

: Assigns priority to picture quality.
