Maximum format
: maximum format than this input can receive.
You can use one of the predefined formats, or
Custom
: in this case,
you will have to define
Maximum picture size
and
Maximum
frame rate
. Note: this parameter allows to allocate the system
resources (CPU, memory, license) to the job. If it is higher than the real
one (for example HD 1080i@30 fps is selected while the input is SD),
then system resources are wasted (but it works). If it is lower than the
real one, then the stream will not be decoded.
If
Maximum format
is set to HD 1080p@60 fps or UHD
2160p@25/30/50/60 fps, color dynamic range parameters are
displayed.
You can select a dynamic range between
SDR
,
HDR-HDR10
,
HDR-PQ10
,
HDR-HLG
and depending of the
Dynamic range
you
must configure the corresponding parameters:
-
If dynamic range is set to
SDR,
define the
Color space
.
-
If dynamic range is set to
HDR-PQ10
or
HDR-HDR10
,
define the
Display primaries
,
White point position
,
Maximum
and
Minimum display mastering
luminance
,
Maximum content
and
Maximum frame
average light levels
.
-
If dynamic range is set to
HDR-HLG
, define the
HLG
signaling
.
The following parameters can be set to
Auto
:
Color space
,
Display primaries
,
White point
position,
Max
and
Min
display mastering luminance
,
Max content light level
,
Max frame average light level
.
If it is the case, their values are extracted from the input stream
if available.
Note that if the parameters are not correctly configured alarms
will be raised and the color dynamic range information are
updated as follows:
-
If the input stream and the configured dynamic range are
not consistent, the input information is broadcast without
modification.
-
If the input stream is HDR and the configured dynamic
range is set to SDR, input HDR information are removed
from the output stream.
-
If the input stream is SDR and the configured dynamic
range is set to HDR, if parameters are configured to Auto
the output stream remains SDR otherwise configured HDR
information are taken in account in the output stream.
Video Compression type
: if set to
Contribution
then the video
contribution streams are supported (refer to
Appendix Technical
Specifications
Section
Decoding Specifications
to know the
supported contribution video bitrates).
