4.4.3 AAC-LD 128kbps (stereo audio)
Specify a call rate for 128kbps AAC-LD. From this call rate and above, "128kbps AAC-LD" is
available. On lower call rates "64kbps AAC-LD" is available.
Stereo audio requires twice the bandwidth as mono CD-quality audio. Therefore we
recommend to enable stereo audio on high call rates only. To enable stereo CD-quality audio
you need to specify a call rate for when stereo automatically should be enabled. On lower call
rates, mono CD-quality audio "64kbps AAC-LD" will be enabled.

Auto: Natural Video Auto will enable transmission of Natural Video from 768 kbps
and above. Reception of Natural Video is in this case always enabled.

Video.
Custom:

as default.
Motion: Optimized for smooth motion video (CIF/SIF for low bandwidths, iCIF/iSIF
for high bandwidths).

Auto:
The system chooses the best of Motion or Sharpness depending on
picture layout and bandwidth.
