Settings (continued)
H.264 Baseline or High
When the encoder is set to H.264 High or H.264 baseline, the settings
items are as follows.
Encoding
display
H.264 Baseline or H.264 High
Framesize
Select the Framesize for each H.264 screen.
The selectable size changes depending on what is selected for the aspect
ratio.
[Aspect ratio 16:9 settings values:
1920x1080, 1280x720, 640x360
]
[Aspect radio 4:3 settings values:
1280x960, 640x480, 320x240

Framerate
Select the Framerate.
[Set values:
30 fps, 25 fps,15 fps, 10 fps, 7.5 fps, 5 fps, 3 fps, 2 fps,
1 fps
]
Bitrate
Select the single encoding compression method from CBR (fixed Bitrate)
or VBR (variable Bitrate).
CBR
:
Encoding is performed at a fixed Bitrate regardless of the
condition of the input image signal. The Bitrate is easy to
predict. Select from the Bitrate Range List.
VBR
:
The Bitrate changes according to the input image signal. The
Bitrate is difficult to predict. Select from the Bitrate Range List.
[Set values:
CBR, VBR

I Frame Interval
Select I Frame Interval. Sets I Frame Interval as the starting point and
encodes.
The smaller the interval, greater the stability of image quality even if the
image changes greatly. With images which do not change image, set the
image quality low. Also, this reduces the time needed for recovery of
images with which packet loss has occurred during multicast.
[Set values:
1, 2, 3, 5, 7, 10, 15, 25, 30, 60, 90, 120
