Gateway and Gateway 4 Manual v1.2
The following table displays the mapping of channels to encoders and decoders for 5.1 channel and
7.1 channel surround sound streams. This is based on the audio channel group order defined in the
SMPTE ST 2110-30 standard. Please note: 6.0 and 8.0 channel streams feature undefined channel
grouping. All channels are the same quality and are not bandwidth limited. The selection of 7.1 or
8.0, and 5.1 or 6.0, for streaming is determined when selecting the encoding algorithm when
creating a program.
Codec Model Note: Only 4.0 channel phase-locked audio is supported in the Gateway 4.
