cd – color depth
For all video windows with the color mode YUV 4:2:2 is used, which means the factor is
cd = 2
For RGB windows two different color modes may be useful, please refer to section
4.2.2 Color capabilities of Eos
Color mode =
RGB 16 bpp
cd = 2
Color mode =
RGB 24 bpp
cd = 3
With the effective bandwidth of the E
OS
system of 100 MBps the sum of the bandwidth of the individual win-
dows may not be bigger than 100 MBps to provide optimal performance:
100 MBps = B
1
+ B
2
+ … + B
n
Bandwidth optimization for video and RGB windows:
All optimization settings are made by means of the X video client, please refer to the section
Displaying video and RGB signals
.
Frame rate
For video sources there are two settings with different frame rate reduction factors selectable to
optimize the bandwidth usage. For RGB sources the static reduction of the frame rate depends on
the input mode and the dynamic frame rate reduction is selectable. (Use the
Fps
setting for video
data and
Reduction
for RGB data respectively and refer to the subsection
Dual RGB Input Card
above)
Color depth
RGB sources can be digitized with 16 bpp or with 24 bpp (depending on the visual class of the
X server).
