Audio Decoding Resource Considerations
A multichannel decode stream counts as three stereo decode streams. If no downmixing and
no dynamic level adjustment is enabled on any stream, the absolute maximum number of
audio decode streams is eight, allowed in one of these (and only these) combinations:
n
Up to four mono/stereo decode streams per FLEX decoding channel
n
Up to one multichannel audio decode and one stereo decode stream per FLEX decoding
channel
n
Up to two multichannel audio decode and two stereo audio decode streams on the first
FLEX decoding channel (with no audio on the second channel)
n
Up to eight mono/stereo decode streams on the first FLEX decoding port (with no audio
on second channel)
Audio Decoding Capacity
n
Dual decoder mode: Up to 4 stereo or one AC-3 5.1

n
Single decoder mode: Up to 8 stereo or 2 AC-3 5.1
and 2 stereo
