Including passthrough programs in an MPTS

Read this section if you want to include passthrough programs in the MPTS. For guidelines and rules about including these programs in an MPTS, see Including passthrough programs.

To pass through a program, you instruct Elemental Statmux to extract a specific program from a source MPTS that is provided by the upstream system.

Get ready

To pass through one or more programs, you need the following information:

• The source MPTS locations: The location where each upstream system source will push each source MPTS. The upstream system can decide on each location and provide it to you. Or you can let Elemental Statmux create a multicast address and then you can provide the upstream system with that location.

• The PID of each program that you want to extract from each source MPTS.

The procedure

You can add passthrough programs while you are creating the MPTS or after you have created it.

Follow this procedure to extract one or more programs from the same source MPTS:

1. On the MPTS Details page where you want to add

2. Select the Add Program Selector button if you want to extract another program from the same source MPTS.

3. the programs, display the Passthrough Programs tab.

4. Select the Add Passthrough Program button. The Add Passthrough Program dialog appears. Complete the fields:

   • Name: Give the program a nickname for your internal use. This name doesn't appear in the outputs MPTS.

   • Stream Endpoints tab: Complete these fields if the upstream system has provided you with the location of the source MPTS.

5. Choose Done. One new entry appears in the list of passthrough programs in the MPTS. The entry has information over three tabs.

6. Select the Basic tab. On this tab, you must identify the following:

   • The program that you want to extract from the source MPTS. Complete the Incoming Program Number.

   • The PID for this program in the output MPTS. Complete the Outgoing Program Number.

   • The optional data to extract from the program: Complete Provider Name, Service Name, or Service Descriptor Passthrough for this program in the output MPTS. Or leave these three fields empty, to omit this information from the output MPTS.

7. Still on the Basic tab, if you want to extract another program from the same MPTS, select the Add Program Selector button on the far right. Complete the fields.

8. Select the Stream Endpoints tab. This tab shows the location of the source MPTS:

   • If you completed the location fields the dialog, this tab shows the information you entered. You can change any of the fields.

   • If you want Elemental Statmux to generate a primary and backup multicast address, leave these fields empty.

9. Select the PID Controls tab. All the programs that you entered in the Basic tab appear. This tab lets you remap the stream PIDs that are in the source program, so that the streams have different PIDs in the output program.

   A field appears for every stream type that Elemental Statmux supports.

   If you leave a field empty,

10. Select the Add Program Selector button if you want to extract another program from the same source MPTS.

11. When you've added all the programs, choose Save.

Review the information:

• Select the Stream Endpoints tab. This tab shows the location of the source MPTS:

  • If you completed the location fields the dialog, this tab shows the information you entered.

  • If you left those fields empty, Elemental Statmux has automatically generated a primary and backup multicast address. Give this information to your contact at the upstream system so that they can push the source MPTS to that location.
