Configure Program Mapping—Quality of Service Levels
The
Service Level
field of the Configure Program Mapping tab screen allows assignment of transrating
priorities and conditions for each program.
provides additional details about the supported
service levels.

Transrating Service
Level Values
Video elementary stream (ES)
is processed through the
transrater.
• -8: highest transrating,
lowest quality.
• +8: lowest transrating,
highest quality.
YES
a
a. DPI sessions carry same QOS settings as network.
Transrated output video ES requires
less bandwidth than input video ES.
No Rate shaping
Video ES processing is limited
through the transrater with null
packet removal.
• Video quantization level is
unchanged
YES
b
b. DPI sessions carry same QOS settings as network.
Output video ES bandwidth will vary
depending on level of ES null packet
removal.
Bypass Transrater
Video ES is not processed
through the transrater.
• Video can be displayed.
YES
Output video ES uses the same
bandwidth as input video ES.
• Can not use more than the
bandwidth of output TS.
Handle As Data
Video ES is not processed
through the transrater.
• Video cannot be displayed.
NO
Output data ES is treated as data
and will therefore use the same
bandwidth as input video ES.
• Cannot use more than the
bandwidth of output TS.
Treat As Async Data
If the input program is a data-only program or all video and audio streams in the
Component PIDs section are unchecked, the
Treat as Async Data
option will appear in
this section. Check this box to disable PCR timing information for this program.
Placeholder ETV
ESs
If the input program does not contain EBIF and EISS elementary streams, a drop
down box for the
Placeholder ETV ES
field will be displayed and editable. This option
allows pre-configuration of an EBIF and EISS ES pair with a stream type of 5 or 192.
When selecting either
EBIF/EISS 5
or
EBIF/EISS 192
the system will automatically
generate the following:
• 1 new ES with a
Preconfigured for PMT
setting of Yes for each EBIF and EISS
stream.
(See “Managing Elementary Streams” on page 156.)
• 2 new Descriptor Rules for each new EBIF and EISS ES.
(See “Managing PMT and ES Descriptors” on page 177.)
