10 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.

To Configure Video Stream Map Using Base Rules 
1 Navigate to the Maps page. 
2 In the tree menu, select Video Stream Map. 
Result: The Stream Map Table is displayed. 
 
 
3 In the Base rules window, enter the Base Value (base values are the initial values 
the operator wants as the very first row in the stream map). 
4 In the Row Increment field, enter row increments for the desired parameters.  An 
increment value of 0 will retain a parameter without increment for each row.  
Typically, increment value of 0 is used for IP address. 
5 In the Channel Offset field, enter desired offset (determines the increment for the 
channel output). 
Example: Entering 10 in the UDP column of the Channel Offset row generates 10 
entries in the stream map for each channel.    
Note: Base Rules can be used at the full-device, card, port or individual channel 
level.  Channel Offset is "don’t care" when implementing Base Rules at the 
channel level. 
6 In the Start QAM Channel field, enter the start and end QAM Channel. 
7 Enter Row Start and Row End (defines rows the base values will be applied to). 
8 Click Implement Rules. TP568

Advanced Settings 
Advanced settings are useful for the following reasons: 
 restrict input sources  
 block PIDs 
 split streams, etc.  
Notes: 
The RF Gateway 1 default database includes a pre-configured video stream map for 
the advanced settings. The default settings accept any source IP addresses, do not 
block the PIDS, break MPTS streams into SPTS for dejittering, and do not ignore 
UDP port.  
The GUI can enable settings such as PCR PID Select, MPTS Dejitter and Blocked PID 
(only for MPTS streams).  
To Configure Advanced Settings 
1 Navigate to the Maps page. 
2 Expand the tree menu to select the desired QAM Channel.

5 In the Source IP Address field, enter the source IP addresses you want your stream 
to listen to.  
 The default  ‘0.0.0.0’ implies don’t care.  
 1 is primary  
 2 is secondary  
 3 is tertiary  
 4 is quaternary 
Note: If the device detects a stream which matches any of these three, it will pass 
it through. 
6 In the Ignore UDP Port field, select True or False.   
Note:  The Ignore UDP Port setting can potentially make the configuration of the 
GbE network easier because only the multicast IP address must be provisioned 
(i.e., remembered), but it assumes that only one stream on each multicast address 
will be present.  Thus, care must be taken to ensure each MPTS has its own 
unique IP address.  Failure to do this will result in problems such as over-
subscription and dejittering issues. 
7 In the PCR PID Select field, the user can choose the following for MPTS streams:  
 From PMT  
 First detected

Notes:  
 We recommend a setting of From PMT. 
 More than 1 PID in a service may have PCR timestamps.  If From PMT is 
selected, the RF Gateway 1 ignores all PCR timestamps except the PID 
specified in the PMT as the PCR PID.  If First Detected is selected, the RF 
Gateway 1 determines the PCR reference PID by whichever PID it first 
receives a PCR timestamp on. 
8 In the MPTS Dejitter field, the user can choose the following mode for MPTS 
Dejitter:  
 One Stream  
 Break Into SPTS  
 The Ref is 0 
Notes: 
 If you have a stat-muxed stream, we recommend a setting of One Stream. 
 The Ref field specifies the service to use as program clock reference for the 
MPTS.  Normally, this field has a value of 0 which indicates the system will 
use the PCR reference of the first PID received with a PCR timestamp. 
 An MPTS stream consists of multiple programs with each program having its 
own embedded PCR reference.  For stat-muxed CBR MPTS streams, any of 
the PCR references may be used to properly dejitter the entire MPTS.  
However, if the MPTS is not CBR, the PCR in a program should only be used 
for dejittering that program.  Therefore, the RF Gateway 1 supports splitting 
an MPTS into individual programs and dejittering each individually with its 
own PCR reference. 
 When creating an MPTS entry in the RF Gateway 1 Stream Map Table, it is 
very important that the Advanced Setting of MPTS Dejitter is set correctly.  If 
the incoming MPTS stream has been created by a stat-mux device and has a 
Constant-Bit Rate (CBR) envelope, the dejitter mode setting should be set to 
One Stream. This setting keeps the stat-muxing intact and passes the CBR 
stream to the output. However, if the incoming MPTS is not stat-muxed and 
is simply rate-limited or rate-clamped, or if it is just a mux of VBR programs, 
the dejitter mode must be set to Break Into SPTS.  The Break Into SPTS 
setting dejitters each program in the MPTS individually based on their own 
PCR. 
9 In the Blocked PIDS field, the user can enter PMT PIDs of programs you want to 
block. The RF Gateway 1 does not support blocking individual audio or video. 
The stuffing PID is 8191.  
Note:

 If an MPTS entry is the only input stream routed to an output carrier, only 
the Null PID (8191) needs to be specified in the blocked PID list.  (All others 
in the list should be set to -1 or removed.)  However, if another MPTS or a 
SPTS is going to be provisioned to mux out on the same carrier as this MPTS, 
the PAT PID must be blocked by entering a 0 in the blocked PID list.  
Blocking the PAT PID causes the PAT to be generated by the RF Gateway 1 
and includes all programs routed to that output. 
 Up to 32 blocked PIDs can be specified in the blocked PID list including 
unreferenced PIDs (e.g. PSIP or EMM PIDs) which are not present in the 
PAT.

MPTS Pass-Through Mode of Operation 
Table based Video Operation can be used generically to enable MPTS Pass Through 
for broadcast applications.    
 Individual PIDs can be blocked as required in the Advanced Settings 
window. The PAT is blocked using default PID 0.  
 If TSIDs are provisioned and the PAT is not blocked, the RF Gateway 1 will 
pass through the incoming source stream as is. 
Note: TSIDs are entered individually for all streams if the PAT is blocked.

Enabling UDTA 
In software version 6.04.XX, a new field has been added to the stream map which 
allows PSIP and EAS to merge. To enable UDTA, merging PSIP and EAS is required 
as the QAM TV tuners rely on PSIP information on the SI BASE PID 0x1FFB and 
EAS also comes in the same PID 0x1FFB. To enable this feature, a new stream map 
entry is added to specify a stream as PSIP or EAS. See screen below. 
 
This new field supports 3 possible values: 
 None 
 PSIP 
 EAS 
The default value for this field is None. 
Below are the constraints that need to be considered when configuring the RFGW to 
work in the UDTA environment. 
 For streams that do not need PSIP and EAS, merge must be set as None.  
 The PSIP setting is supported only for stream map entries configured as MPTS. 
 The EAS setting is supported only for stream map entries configured as DATA. 
 In case of replication of streams marked as PSIP or EAS, the streams should be 
marked as PSIP or EAS across all the channels where they are configured. 
 Only one PSIP and one EAS is allowed per QAM channel. 
 For entries configured as SPTS and Plant, this option will be disabled.
