SDI Audio
Matrix

Per SMPTE 272/299M SDI supports embedded audio Groups 1, 2,
3, 4. This device can route channels from 2 Groups concurrently. 1
and 2 or 3 and 4. Each group has 2 channels and each channel is a
stereo pair. Fpr example, Group 1 3/4 can be routed to any of the 4
audio encoders.

Group 1 1/2
Group 1 3/4
Group 2 5/6
Group 2 7/8

controls channel ordering; analog to the 3-bit 'acmod' code.

0 = N/A
1 = 1/0 (C channel)
2 = 2/0 (L and R
channels)
