Notes: A Transport Stream becomes overrated when the sum of the component bit
rates exceeds the Transport Stream bit rate. This can occur when the
master Transport Stream increases the bit rate of a component that is
included in another Transport Stream and that other Transport Stream
cannot compensate the increase by the decreasing of the null packets bit
rate. As long as IP and ASI outputs are also configured with bit rate tracking
set to maximize video, they will automatically increase their bit rate in line
with the
Satellite Modulator (or Master TS ) output in order to avoid being
overrated.
Enabling Bit Rate Tracking
Select the Transport Stream for which bit rate tracking is required.
Notes: If the Transport Stream is not yet created, build it by following the steps in
Manual Configuration via the Web Pages or in Manual Configuration via the
Front Panel.
Bit rate tracking mode is set to Maximize video by default, but this step is
included in the process to ensure success.
In the web browser navigate to Service Configuration and click the TS in the
Outputs panel. Set the Bit rate tracking mode to Maximise video .
Figure 3.18 Enabling Bit Rate Tracking Mode
Alternatively on the front panel navigate to Bit rate Tracking and select the
Transport Stream. Set the Enable Bit rate Tracking to Maximize video .
Set Weight of Component
There is also a weighting parameter for each video component. This provides the
user with control over how the available bit rate should be shared between the video
components in a multi-program Transport Stream.
