Manual PID Injection - Overview
The DTA's ingress logic requires Service Information (SI) to present a list of programs or PIDs to map to the output. Manual
PID injection is used to pass a program or PID that is not referenced in the SI. The most common example of manual PID
injection is a transport stream from an SI generator or Transport Stream spooler. Manual PID injection mode is useful for:
PID injection - passing a PID or PIDs unreferenced by the SI/PSI/PSIP generated by the DTA. •
Program injection - passing a PID or PIDs and referencing them in the SI/PSI/PSIP generated by the DTA. •
SI/PSI/PSIP injection - passing PIDs that are tables. •
Elementary Stream Addition - adding a PID or PIDs to an existing program (or programs). •
This article will explain in detail how to use manual PID injection modes, and provide examples of the process in use.
Requirements
Attention: referenced third-party software is suggested; Adtec does not endorse any third-party software product over
another.
Telnet/ssh client: http://the.earth/li~sgtatham/putty/latest/x86/putty.exe •
File transfer utility: http://winscp.net/download/winscp425.exe •
Text Editor: http://www.editpadpro.com/download.html ( note: program is not freeware) •
Correct version of the DTA software.
must use version 6.02.04a (or higher) software. ♦
•
Know the value(s) of the PIDs you want to inject. •
A manualpidconfigX.xml file with entries that match your application. •
Procedure
Step Action
1 Connect the transport streaming source device to the desired input.
2
Edit the manualpidconfig file with the desired values.
(You can either get the file from the unit or use one of the samples located at adtecftp.com.
3 Transfer the file back to the unit (to /var/local/lib/asimux).
4
From the unit's Front Panel or browser-based GUI, configure the port that the transport streaming source device is
connected to as follows:
Port State = Enabled
Port Mode = Manual
Tables = None
5 Reset the unit.
6
Confirm that PIDs are present from the Mappings page.
They will show up as program 100000, and be listed under "Components".
Examples/Samples
PID Injection
This sample will pass an unreferenced PID, 0x1234 from Input 5:
<?xml version="1.0" encoding="UTF-8"?> <configuration xmlns:xi="!http://www.w3.org/2001/XInclude">
<manual_pid_config index="5"> <pid> <pid_in base="16">1234</pid_in> <pid_out
base="16">1234</pid_out> <stream_type>Private</stream_type> </pid> </manual_pid_config>
</configuration>
SI/PSI/PSIP Injection
The sample below will pass PIDs ox10 (NIT) and Ox11 (SDT) from Input 5. When using this mode you must turn off NIT and
