AWS::MediaLive::Channel Ac3Settings

The settings for an AC3 audio encode in the output.

The parent of this entity is AudioCodecSettings.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{ "Bitrate" : Double, "BitstreamMode" : String, "CodingMode" : String, "Dialnorm" : Integer, "DrcProfile" : String, "LfeFilter" : String, "MetadataControl" : String }

YAML

Bitrate: Double BitstreamMode: String CodingMode: String Dialnorm: Integer DrcProfile: String LfeFilter: String MetadataControl: String

Properties

Bitrate

The average bitrate in bits/second. Valid bitrates depend on the coding mode.

Required: No

Type: Double

Update requires: No interruption

BitstreamMode

Specifies the bitstream mode (bsmod) for the emitted AC-3 stream. For more information about these values, see ATSC A/52-2012.

Required: No

Type: String

Update requires: No interruption

CodingMode

The Dolby Digital coding mode. This determines the number of channels.

Required: No

Type: String

Update requires: No interruption

Dialnorm

Sets the dialnorm for the output. If excluded and the input audio is Dolby Digital, dialnorm is passed through.

Required: No

Type: Integer

Update requires: No interruption

DrcProfile

If set to filmStandard, adds dynamic range compression signaling to the output bitstream as defined in the Dolby Digital specification.

Required: No

Type: String

Update requires: No interruption

LfeFilter

When set to enabled, applies a 120Hz lowpass filter to the LFE channel prior to encoding. This is valid only in codingMode32Lfe mode.

Required: No

Type: String

Update requires: No interruption

MetadataControl

When set to followInput, encoder metadata is sourced from the DD, DD+, or DolbyE decoder that supplies this audio data. If the audio is supplied from one of these streams, the static metadata settings are used.

Required: No

Type: String

Update requires: No interruption
