The transcoder supports decoding for HE-AACv1/HE-AACv2, but only encoding
only for AAC-LC
Audio streams in the transport stream that are not transcoded are always passed through to
the output. This includes AC-3 (Dolby Digital) audio components.
8.3.3.1 Audio Configuration
The audio transcoders are shared between the channels of the board. The user can allocate
different numbers of transcoders per channel as long as the maximum number is not exceeded.
An audio transcoder is added by clicking on the “Create” button on the bottom of the Audio
page. An audio Transcoder is removed by clicking on the “-“ button to the right of the
Transcoder. When a Transcoder is removed from one channel, it can be used on another
channel.
Output
The codec type. Available options: MPEG-1 and AAC-LC. AAC-LC
includes container selection.
Bitrate
Supported range of bitrate for each encoder type. See details per codec
in above sections.
Channel Mode
Channel Mode: Stereo, Dual Mono or As Source. As Source – output
channel mode follows input channel mode.
Audio Source
Select the audio PID to be transcoded based on either language or a
more advanced priority list.
“Select Any Language” - a random language in the original service.
“Current languages” - select from a list of incoming audio languages.
“Advanced Selection” - possibility to set up a prioritized selection based
on codec type, PID value and/or language
