Audio
MPEG-2 TS/UDP
| Parameter | Description |
|---|---|
| Audio ID Type | Choose the audio stream type used to identify the input audio stream. Possible values: PID, Language |
| PID | Numerical identifier of the audio track. Or auto to use any language in the stream. |
| Language | Audio track languages in ISO 639 format (3letter code, lowercase). This can be defined using a comma to separate, or enter 'auto' to use any language. |
| Decoding capability | Select Dolby if you decode Dolby Digital or Dolby Digital Plus. Select Dolby E if Dolby E decoding is required (SDI or SDI/IP only). Specific licenses are required for Dolby decoding. |
SDI
| Parameter | Description |
|---|---|
| Type | Type of audio to create (1) Audio (2) Aggregated audio: Used to extract up to 5.1 audio tracks from the SDI audio pairs |
| Audio Pair | Only available with Audio type. Select the stereo audio pair (Group/Pair). |
| Audio format | Only available with Audio type. 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. |
| Decoding capability | Only available with Audio type. Select Dolby if you decode Dolby Digital or Dolby Digital Plus. Select Dolby E if Dolby E decoding is required (SDI or SDI/IP only). Specific licenses are required for Dolby decoding. |
| Dolby E program | Only available with Dolby E decoding capability. The Dolby E algorithm is optimized for handling discrete multichannel audio programs and multiple audio programs. Encoded audio channels are grouped as programs that are typically mono (one channel), stereo or matrix surround (Lt/Rt) encoded (two channels), or discrete six-channel audio with five full-range channels and a bass-only Low-Frequency Effects (LFE) channel (5.1 channels). Dolby E makes use of the available data space only for the number of audio channels that are present, so requiring less space if fewer than eight audio channels are used. The channel configuration is determined at the time of encoding, allowing users to choose the best mode for the specific application. Possible values: See table below. |
| Mode | Only available with Aggregated audio type. Defines the number of channels to configure. In case of 5.1 audio, 6 channels need to be configured: Left, Right, Center, LFE, Left surround and Right surround. |
| PCM audio mapping | Only available with Aggregated audio type. You can aggregate multiple SDI audio pairs to have up to 5.1 streams. Associate the Group/pairs SDI (Gn Pn) with Left and Right as needed by scrolling the menus.  |

SMPTE ST 2110
| Parameter | Description |
|---|---|
| Stream Index | Index of stream within the SDP file. 1 is the first stream. |
| SDP File Location | Location of SDP file describing the input stream. Either a URL or a file location. |
| Channel Group Index | Index of channel group within the SDP audio stream. 1 is the first channel group. |
| 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. |
| Decoding capability | Select Dolby if you decode Dolby Digital or Dolby Digital Plus. Select Dolby E if Dolby E decoding is required (SDI or SDI/IP only). Specific licenses are required for Dolby decoding. |
| Channel Order | Select if the audio channel groups should be automatically read from the SDP file or manually specified. Possible values: M, DM, ST, LtRt, 51, 71, 222, SGRP See table below. For multi-channel audio, Live Encoder relies on the SDP file to specify how audio channels are grouped, but the channel order parameter that specifies the quantity and order of audio channels is optional in the SDP file. If the channel order is not specified, you can manually specify it.  |
Channel order values
| Channel grouping symbol | Quantity of audio channels in group | Description of group | Order of audio channels in group |
|---|---|---|---|
| M | 1 | Mono | Mono |
| DM | 2 | Dual Mono | M1, M2 |
| ST | 2 | Standard Stereo | Left, Right |
| LtRt | 2 | Matrix Stereo | Left Total, Right Total |
| 51 | 6 | 5.1 Surround | L, R, C, LFE, Ls, Rs |
| 71 | 8 | 7.1 Surround | L, R, C, LFE, Lss, Rss, Lrs, Rrs |
| 222 | 24 | 22.2 Surround | Order shall be per SMPTE ST 2036-2, Table 1 |
| SGRP | 4 | One SDI audio group | 1, 2, 3, 4 |
| U01…U64 | As indicated by Grouping Symbol (Unn where nn is the number of channels in the group) | Undefined | None specified, the order of channels in this group is Undefined. |
- The Channel Order described above was developed such that phase-coherent multichannel audio groups (or simply mono channels) can have their channels clearly defined within SDP. It does not attempt to provide any “higher level” description of the purpose of the audio channels (such as “secondary language”). It only addresses fixed multichannel audio groups commonly used at the time of publication of this document, and does not attempt to deal with object-based audio.
- The 5.1 Surround and 7.1 Surround channel orders defined in Table 1 are based on typical ordering of those channels found in SMPTE ST 2035, EBU R 123, and SMPTE ST 429-2.
