Note: Components cannot be directly added to Reflex groups, only to services
within a group.
3.7.18.3 How to Set up Internal Reflex Group Parameters
Once all components to be statistically multiplexed are added to the Reflex group,
you can set up the group parameters. For this, do the following:
1. In the Outputs widget, select the Reflex group you want to set up.
2. In the Properties widget, set a name for the group in the Group Name field.
3. For the Seamless Buffer Delay option, specify the encoding delay your
application can tolerate. The larger the delay, the better the output video quality
is.
4. If you want to use the maximum available bit rate in the Transport Stream, select
On under Use Max Available Bit Rate. Otherwise, set Use Max Available Bit
rate to Off, and specify a bit rate for the group under Group Bit rate.
Note: The sum of the bit rates of the components outside the Reflex group plus
the bit rate set in the Group Bit rate field cannot exceed the total bit rate of
the Transport Stream.
3.7.18.4 How to Customize the Internal Reflex Properties of Individual Components
To customize the Reflex related properties of the individual components, do the
following:
1. Select the video component whose Reflex related properties you want to
customize.
Note: Even though all sorts of components can be added to a Reflex group, only
video components will be under Reflex control. More importantly, the bit
rates of component types other than video will not be included in the group
bit rate.
2. In the Properties widget, select the appropriate Preset option.
Note: If you want to use presets for a given video encoding profile, choose the
Auto option for Preset in the Properties widget. All parameters will be
populated for you based on the encoding profile selected. Otherwise,
choose the Manual option.
3. If the Preset is set to Manual, adjust the bit rate range for the video component
in the Min Seamless Bit rate and Max Seamless Bit rate fields. The video bit
rate can be varied by the Reflex between the values set in the Min Seamless
Bit rate and the Max Seamless Bit rate fields.
Note: The delay shown under Buffer Delay is the same as the delay set under the
Reflex group properties. The Buffer Size is the buffer size corresponding to
the set delay.
