Cinegy Playout contains internal mapping of audio inputs to audio outputs. The "Audio" tab allows you to set up sound processing schemes, including configuration of AC-3 decoder and encoder parameters, if needed.

A Sequence inserted into a Story and then used in a Rundown is processed as a media file with a certain number of audio tracks defined by the audio mapping inside the Sequence. These audio tracks are considered as audio inputs for the playout engine and are mapped according to defined rules to the output playout channels. Playout engine outputs are fixed to 8 stereo audio pairs.

Refer to the Output Audio Channels and Mapping article in the Cinegy Desktop Manual for more information on audio mapping inside Cinegy Sequences.

By default, four stereo audio channels are mapped to four stereo output channels.


The graphic relations represent the mapping rules inside playout engine that define how the input channels are connected to the output channels.

Audio Input Configuration

To set up a particular input channel, press its corresponding button in the "Input" column; the following dialog appears:


Here you can specify whether this channel will be used, by ticking off the "Used" checkbox, and define the output channels mapped to this input channel. Press the "OK" button to apply the channels settings.

The changes will be reflected on the graphic scheme:


AC-3 Decoding Settings

To use an AC-3 decoder in the input audio channel being configured, select the corresponding checkbox in the "Audio input" dialog; this will enable 4 more output channels:


Define the compression mode choosing the desired option (Line, RF, Custom or "No Compression") from the corresponding drop-down list.

Define the output channels mapped to this input audio channel by choosing the desired values (from 0 to 63) from the corresponding drop-down lists.

Select the "PCM passthrough" checkbox to pass PCM encoded audio to the output.

Use the "Metadata channel" drop-down list to define a virtual metadata channel to which the audio decoder will connect.

Having configured the AC-3 decoder audio settings, press the "OK" button to apply your settings.

Audio Output Configuration

Settings for the output channels can be configured in a similar way to the input channels.

Press the button of the corresponding channel in the "Output" column; the following dialog box appears:


Select the "2 Channels" encoding type from the drop-down list for stereo audio encoding:


Select the "Clean audio output" option to target specific audio output groups with clean refined audio.

The "Embed DTMF" option allows to embed DTMF tone into output audio signal. The DTMF tones configuration is performed on "DTMF" tab.

Also specify the input channels settings and press "OK" to apply changes.

Loudness Control

Selecting the "Loudness control" option enables the preset configurations provided by Minnetonka Audio Software.

To use the Loudness Control feature, a special license should be provided by Minnetonka Audio Software obtainable through Cinegy as a paid extra. For more details about purchasing licenses, please contact the Cinegy Sales Team.
Selecting the "Loudness control" option without the proper license, will prevent the Cinegy Playout Engine from starting.

Press the "Settings" button located next to the "Loudness control" option. In the revealed window specify the following loudness control settings:

  • Profile – select the required preset profiles from the drop-down list of available profiles:

    All profiles, depending on the implemented settings, achieve technical compliance in accordance with loudness recommendations based on ITU-R.BS1770-4.
  • Target Loudness Level – use the arrows_buttons buttons to define the Target Loudness Level at which the incoming average level normalization is aimed.

  • Maximum True Peak – define the threshold level of the True Peak Limiter applied at the output stream of the processing chain.

  • Adaptation – define the amount of loudness adaptation applied to the incoming signal.

  • Program Loudness – define the Program Loudness level of the source signal.

  • True Peak Limiter – select/deselect this option to enable/disable the True Peak Limiter.

  • Compliance Window – define the duration, in seconds, of the last part of the program being played.

  • Compliance Speed – define the amount of Loudness Units (LU) gain or attenuation allowed per second.

  • Average Maximum Gain – use the drop-down list define the maximum gain applicable to the average program level processed according to Compliance Window and Compliance Speed.

  • Average Maximum Attenuation – use the drop-down list define the maximum attenuation applicable to the average program level processed according to Compliance Window and Compliance Speed.

    It is not recommended to set the "Average Maximum Attenuation" value greater than 6 LU.

Nielsen Watermarking

Cinegy Air uses the 4.1.2 Nielsen SDK version. This SDK version requires that the customer provides proof of certification, in the form of a license file, to be added to the Cinegy Playout Engine installation folder. If you have not passed formal certification and do not have this file, please do not install this release version and contact your Nielsen or Cinegy representatives to discuss certification. A test license can be provided for evaluation which will insert standard test identifiers.

The "Nielsen watermarking" group provides parameters for Nielsen Watermarking encoding/decoding configuration. To enable watermarking functionality choose the required Nielsen watermarking type by selecting the corresponding option:


The parameters can be configured for each channel separately. This means that in case of simulcast each version of the playlist may have its own watermarking parameters.

All output devices used in the same channel will have the same watermarking parameters applied (SID, watermarking type, etc.).

NW Type Configuration

Please ensure that all parameters for Nielsen watermarking and CBET (if selected) options are filled in fully and correctly otherwise, the engine will fail to start. Please deselect these options to restart engine correctly.

The following parameters are available for the NW type configuration:

  • SID – Nielsen source ID. One or more SIDs are assigned to each content provider or distribution source. Included as a component of each watermark, the SID uniquely identifies the distribution source.

  • Check digits – two upper-case alpha characters, corresponding to the SID that are assigned by Nielsen.

  • Distribution type – specifies the watermark type: Program Content or Final Distributor. Typically Program Content watermarks are assigned to syndication content or to content providers (i.e. broadcast networks etc.), while Final Distributor watermarks are assigned to local broadcast affiliates or to cable network content.

  • Watermarking type – defines the type of watermarking to activate this session. The following types are available for choosing:

    • NAES II – for Legacy NAES II watermarking;

    • NW watermarking;

    • Both NAES II and NW are activated.

  • Existing watermarks – determines the method of handling a second Final Distributor code if Final Distributor codes are already present in the stream (NAES II HF and NW). The options are:

    • Overwrite – the original watermarks are replaced with the new ones.

    • Preserve – the pre-existing watermarks are left intact; new watermarks are inserted only in portions of the audio stream where there are no pre-existing watermarks.

Please note that legacy NAES II watermarks will be overwritten, and Nielsen watermarks NW will be appended. Unlike NAES II watermarking, Nielsen watermarks processing does not support the overwriting of audio codes that are present in the stream before watermarking process begins. Instead, the watermark engine leaves space for a second (and possibly a third) Final Distributor SID in the program band.
Nielsen recommends skipping LFE channel, surround left channel and surround right channel from NW encoding to fix audibility issue.

CBET Type Configuration

The CBET type configuration is similar to the NW one. Once the CBET option is selected, the following parameters can be configured:

  • CSID – Nielsen CBET Source ID.

  • Check digits – corresponds to the CSID and assigned when the Nielsen Watermark SDK is delivered.

    If the CBET check-digit string does not match the CSID, the authenticator does not permit watermarking with the CSID.
  • Existing WMarks – select either "Preserve" or "Overwrite" option from the drop-down-list.

If the combination of CBET and NAES II watermarks is set, the output will contain CBET, NAES II, and NW watermarks.
