Video Format
The SCS8000E MCU supports the H.264 and H.263 video compression
standards.
Resolution
If “H.264” is selected as the video format, the resolution of CIF, 4CIF,
720Pand 1080p/i can be selected from the drop-down list; while for the H.263
video format, only CIF resolution is supported.
Frame Rate The maximum frame rate is 30.
Audio Format
Select the compression format from the drop-down list. General, the higher
the audio sampling frequency, the better the quality of out-put sound.
Image Process
Only the opening of image processing functions will be allowed to call
terminals with different resolution during meeting. The processing resource is
exclusive for the conference selected the Image Process, in this case the
other conference can not enable CP function or call different resolution MTs.
If a conference has selected the resolution of 1080p/i the Image Process
function is unavailable.

Video Format
Select the format of the second video source, including
H.263+/H.239 and H.264/H.239. “H.264/H.239” means that
the H.239 protocol is used and the format of the second video
source is H.264.

Video Quality
including Speed Precedence and Quality Precedence. Quality
precedence policy ensures the image quality during the video
transmission, so that the picture is free of mosaic or blue
screen; while the speed precedence ensures the smoothness
and consistency of the video.
VA Sensitivity
Under voice activation, the spokesman switching is
implemented by judging the voice status of the MT. After the
MT becomes the spokesman, no matter whether the MT is
speaking, other MTs cannot seize its spokesman position in a
set VA sensitivity period. Beyond this period of time, if the MT
does not speak either, other MT with audio output will
automatically become spokesman.
