Parameter Values Description
Closed GOPs Off, On
Enables or disables the usage of Group of Pictures in
which the predicted frames can have their reference from
outside the group.
Delay
Displays the actual video encoding delay. Read only
parameter.
Inloop Filter High, Normal, Low, Very Low, Auto
Sets the characteristics of the filter placed in the feedback
loop of the encoder. Applying the filter to the picture can
increase picture sharpness.
SEI Encapsulation
Mode
2
Combined, Mediaroom
Sets the SEI messages in combined mode where all the
SEI messages are combines into one NAL unit or into
Mediaroom mode compliance where each SEI message
has its own NAL start.
1
Only applicable when the video profile is set to MPEG-2.
2
Only applicable when the video profile is set to H.264.
Specific Notes on Second Video
The Main Video and the Second Video (this also applies to the PiP Component)
originate from the same input; therefore they naturally share the timing information:
• They have the same clock reference (PCR) value in the stream, whether they
use embedded PCR or a separate PCR component.
• Their timing (PTS) are aligned, and it is therefore possible to share audio
components from the same card.
Restrictions on the Second Video Compared to the Main Video
• The Second Video supports SD encoding only and does not support HD
encoding resolutions. The codec for the secondary video component is
restricted to that detailed in the table below.
Table 5.10 Restrictions on Secondary Video Component Coding Standard
Primary Video Component Coding Standard Secondary Video Component Coding Standard
SD MPEG-2 Off, SD MPEG-2, SD H.264
SD H.264 Off, SD H.264
HD MPEG-2 Off, SD MPEG-2
HD H.264 Off, SD H.264
• The Second Video component (this also applies to the PiP component) cannot
be added to the same service as the Main Video component. It can be only be
added to a separate service.
• The Second Video can be turned Off by setting the Video profile to Off.
• The Second Video only supports CBR, and therefore does not support VBR and
Reflex.
• The Premium License does not apply to the Second Video.
