Setting Up the Statistical Multiplexing Encoding Rate

To Set Up the Statistical Multiplexing Encoding Rate
Proceed as follows to set up the Statistical Multiplexing Encoding Rate:
1. From the user interface of the D9054 HD Encoder click the Video tab, expand
the H.264 icon, expand the Statistical Multiplexing icon and click the Encoding
Rate icon from the sub-pages.
Note: The maximum video rate must be higher than (or equal to) the default
video rate, and the default video rate must be higher than (or equal to) the
minimum rate.
2. Set the Maximum (video) Rate for the Elemental Stream (ES).
This setting is used to prevent the rate for a service from exceeding a specified
value. The permissible range is from 3 to 20 Mbit/s.
Example: A typical application is that you want to extract programs from the
statistical multiplex bouquet and forward these programs separately. In that
case, you may need to limit the maximum rate of each channel to extract so that
you avoid overflow of the equipment that handles the extracted statmux
programs.
The maximum video rate limit setting does not imply that the encoder will try to
go up to that rate, but simply that it will not exceed that rate. The maximum
video rate during operation may be lower if the statmux pool size does not
allow room for it.
