# Live service lineup encoding parameters

For each source, you can edit the following parameters depending on the source input type, either MPEG-2 TS/UDP or SMPTE ST 2110.

## MPEG-2 TS/UDP lineup

| Parameter                     | Description                                                                                                                                                                 |
|-------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Stream address                | Input stream unicast or multicast IPv4 address                                                                                                                            |
| Port                          | Port used to capture the input stream                                                                                                                                       |
| IGMPv3 source filtering       | IGMP source IP address. List of addresses allowed in IGMPv3 using a comma to separate.                                                                                      |
| Input synchronization mode     | Input can be synchronized based on PMT program ID or on VCT major and minor channel numbers or the stream PIDs. Make a selection based on the information present on the input stream. |
| FEC port                      | Port used for FEC<br>Possible values: From 1 to 65535                                                                                                                       |
| **Streams**                  | For each source select which streams will be used and enter the PIDs: List of stream identifiers using a comma to separate.<br>**Note:** If no PID is specified, default PID will be used. |

## SMPTE ST 2110 lineup

| Parameter                     | Description                                                                                                                                                                 |
|-------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Stream Index                  | Index of stream within the SDP file. 1 is the first stream.<br>Possible values: From 1 to 1000                                                                                   |
| SDP File Location             | Location of SDP file describing the input stream. Either a URL or a file location.<br>**Note:** The **SDP File Location** must be specified when Live Encoder service is configured with [MediaComposer input type and an SMPTE ST 2110 source](https://docs.mediakind.com/beam/live-encoder/configure/input/input-stream-source#configure-an-smpte-st-2110-input-with-sdp-files), but [if you are using NMOS](https://docs.mediakind.com/beam/live-encoder/configure/input/input-stream-source#configure-an-smpte-st-2110-input-with-nmos), you don’t need to specify it, otherwise it will be ignored since the NMOS Controller supplies the SDP file. |
| Audio format                  | Select if the audio format should be automatically detected or forced. For uncompressed/Dolby E Passthrough select either 'AES Uncompressed audio' or 'Dolby E' as the input format, and 'SMPTE302/Dolby E Passthrough' from the encoding menu. Dolby E input will not work with Dolby AC4. To decode/reencode Dolby E select Auto or SMPTE337 compressed input as the input format. |
| Channel Group Index           | Index of channel group within the SDP audio stream. 1 is the first channel group.<br>Possible values: From 1 to 65535                                                                                   |
| DPI PID index                 | Specifies the index to the DPI PID which will carry the resulting splice_info_sections.<br>Possible values: From 0 to 65535                                                                                       |
