Channel Mapping Overview
The BAP organizes the audio channels into paths. ( Figure 2 ) Each SDI has four output paths with the
following default channel mapping:
• Output path 1 includes channels 1-6
• Output path 2 includes channels 7-8
• Output path 3 includes channels 9-14
• Output path 4 includes channels 15-16

• how to map the audio channels, refer to “ Channel Mapping ”.
Dolby Encoder Work-flow Overview
The Dolby Encoder feature enables you to specify if an output path is encoded using Dolby Digital
or Dolby Digital Plus. You also have the option to bypass the encoder and configure the output
paths to include PCM data instead.
Embedding Dolby Digital or Dolby Digital Plus Data
You can configure the BAP to embed Dolby Digital or Dolby Digital Plus, using the options available
in DashBoard.
The encoded audio and metadata are carried together as a data stream on two regular digital AES3
audio channels. When the Dolby encoder is enabled for an SDI path, the output from the encoder is
