In the Pid Map Value (PMV) field, enter the following guidelines:
For MPTS and data streams, no PMV value may be entered (PIDs are not
remapped).
For SPTS and plant streams, the PMT PID value is determined by the
following equation:
–
PMT PID = (PMV+1)*16
–
All elementary stream PIDs will be incrementall based off the PMT PID
calculation.
11
In the Data Rate field, enter values according to the following guidelines.
SPTS or MPTS Stream Type - No data rate may be entered. Playout rate is
determined by timing recovery.
Data - A data rate should be selected to play out at a constant configured rate
of 1-38812 Kbps and within the limitations of the output bandwidth of the
QAM Output Channel.
Plant - A data rate should be selected to play out at a constant configured rate
to include the SI data and within the limitations of the output bandwidth of
the QAM Output Channel.

Notes:
When muxing 2 incoming MPTS streams to 1 output carrier (or when muxing
1 MPTS with 1 or more SPTSs), the operator is responsible for preventing
PID conflicts and over-subscription of the carrier.
To prevent PID conflicts, the operator must know what PIDs are being sent
down in each of the MPTS streams, and if there are conflicts, they must be
fixed at the source device. When muxing an MPTS with SPTSs streams, the
operator must carefully choose PMV values for the SPTS streams that do not
cause PID conflicts between the remapped SPTS streams and the passed-
through MPTS stream. (The PMV value determines the PMT PID of the
remapped SPTS and all elementary stream PIDs immediately follow the PMT
PID in order. The PMT PID = (PMV+1) *16.)
To prevent oversubscription of the carrier, the operator must know the
maximum bitrates of all the services being mapped to the carrier and make
sure the total bitrate can not exceed the capacity of the QAM carrier.
Automated Video Stream Map Configuration
Using advanced stream map generation, the operator can add multiple rows to the
stream map simultaneously.
