Encoding interval
The Encoding interval slider determines the interval at which
images are encoded and transmitted. This can be particularly
advantageous with low bandwidths. The image rate in ips
(images per second) is displayed next to the slider.
Video resolution
Select here the desired resolution for the video image. VGA
(640x480) and QVGA (320x240) resolutions are available.
Expert Settings
if necessary, use the expert settings to adapt the I-frame quality
and the P-frame quality to specific requirements. The setting is
based on the H.264 quantization parameter (QP).
GOP structure
Select the structure you require for the Group of Pictures.
Depending on whether you place greater priority on having the
lowest possible delay (IP frames only) or using as little
bandwidth possible, you choose IP, IBP or IBBP.
I-frame distance
Use the slider to set the distance between I-frames to Auto or
to between 3 and 60 . An entry of 3 means that every third
image is an I-frame.The lower the number, the more I-frames
are generated.
I-frame quality
This setting adjusts the image quality of the I-frames. The basic
setting Auto automatically adjusts the quality to the settings for
the P-frame video quality. Alternatively, use the slider to set a
value between 9 and 51. The value 9 represents the best image
quality with, if necessary, a lower frame refresh rate depending
on the settings for the maximum data rate. A value of 51 results
in a very high refresh rate and lower image quality.
P-frame quality
This setting adjusts the maximum image quality of the P-frames.
The basic setting Auto automatically adjusts to the optimum
combination of movement and image definition (focus).
