Plain video mode
Alternatively to the standard configuration where always O
MNI
S
CALER
are used to display video or RGB input data,
this section describes a possibility to display video and RGB data in a system without O
MNI
S
CALERS
. This is further
referred as
plain video
.
Plain video is only recommended for systems where few video or RGB windows shall be
shown, where those windows do not need to be upscaled and where genlocking is not
required.
System requirements
For plain video mode the following system requirements have to be fulfilled:
Operating system
Windows XP
Windows driver suite
release 4.2 or higher

System requirements for plain video
Software configuration
For plain video the following settings must be configured:
•
The color depth of the system must be set to
Medium (16 bit)
(
Start -> Settings -> Control Panel ->
Display -> Settings
)
•
The cursor must be configured in any case as hardware mouse pointer, more information in section
Appropriate cursor for video applications
•
When starting the software video.exe, the option
/v
must be used with the value
1
, e.g.:
video /d:frg0 /v:1
Please refer also to section
Bandwidth considerations
Plain video is more restrictive towards bandwidth consumption. Therefore you should first check the feasibility of
a configuration. Please check section
4.1.8 Amount of video and RGB windows
for the principal understanding of the
calculation of bandwidth consumption. The column
bandwidth per window [MBps]
of the
provides band-
widths of the most common content types; the proximate formula helps to check the feasibility of a configura-
tion. The overall available bandwidth when using plain video mode can be assumed as given in the table below:
