Note: It is possible to set Input Detection to Auto Detect and Configure if using
the Interleaved format.
7. Click on the Encode tab.
8. Set the Profile to UHD HEVC Main 10 Profile Level 5.1 High Tier 4:2:0 10 bit .
Note: For 4:2:2 video encoding a license must be purchased and the Profile set to
UHD HEVC Main 10 Profile Level 5.1 High Tier 4:2:2 10 bit .
9. Set the Buffer Mode to either CBR, Low Delay or Mega Low Delay depending
on the picture quality and end to end delay required. See section 3.9 for more
details.
10. Set the Video Bitrate to the required value depending on the bandwidth
available and picture quality required . See section 3.9 for more details and
recommendations.
3.12 How to Set up Bit Rate Tracking
Overview
The bit rate tracking feature ensures that the output TS rate is automatically fully
utilized. In case of a bandwidth change the tracked components change their bit rate
accordingly.
The bandwidth can be influenced typically by the bit rate of the Transport Stream but
other factors can also trigger a change.
Weighting is used to proportionally distribute the change in bandwidth among the
components in a multi program transport stream. A weight value between 2 and 20
can be assigned to a video component and so the component becomes a tracked
component whose bit rate is influenced by the Transport Stream. The bit rate of
Fixed weight components do not change and a Minimum setting will result in the
video component bit rate being configured at the lowest bit rate allowed by its video
profile.
As individual components can be included in multiple Transport Streams, a Master
TS has to be specified which will be the controlling factor that determines the bit rate
of the tracked components, which will be reflected in all Transport Streams that a
component is included in.
For example: An IP output transport stream may have significantly more bandwidth
than the Satellite Modulator output and the same TS is to be transmitted over both
interfaces. The Satellite Modulator TS is defined as the
Master TS (by default) so
that it is not overrated. The common IP output components will have the same bit
rate but the IP TS will not be fully utilized.
