If AC-3 audio is present on the input signal (embedded SDI or AES), this can be passed through
to the encoded output service.
8.2.3.1 Audio Configuration
The one (SD mode) or two (2xHD) general purpose audio encoders per SDI input channel shall
always be available in the GUI. These encoders can be turned off by configuring the Encoder
Type to off.
The MPEG-1 and AAC-LC encoders that can be dynamically distributed between the channels
are added to a channel by using the “Create” button in the bottom of the Audio page. The “-“
button to the right of each encoder will remove the audio encoder from the channel. After an
audio encoder is removed from one channel, it can be used on another channel. Up to 8
encoders can be added to one channel.
Encoder Type The codec type. All encoders supports: MPEG-1 and AAC-LC,
General purpose encoders support also HE-AACv1, HE-AACv2,
Pass through and off.
Container AAC container. LATM and ADTS are supported.
Delay The Audio Delay Adjustment is valid for encoder with SDI input and
Audio encoder instances greater than 2 (ie software encoders). The
valid range available is from +50 to +50 ms.
Bitrate Supported range of bitrate for each encoder type. See details per
codec in above sections.
Mode Channel Mode: Stereo, Mono or Dual Mono.
Source
Embedded audio selection. 8 embedded stereo pairs can be chosen
for stereo and dual mono. One of the 16 channels can be selected
for mono encoding.
PID The PID value of the compressed audio stream.
Language Three letter audio code used in PMT. Example “nor”, “eng”
