MPEG Decoder Function
MPEG
The MPEG function decodes MPEG1 or MPEG2 data streams
into two-channel PCM output. The selection of MPEG1 or 2 is
made automatically from the input stream. All parameters are
the same as for the AC3 command except the following.
Pink Noise Generator Function
PNG
The Pink Noise Generator function produces pseudo-random
noise sequence outputs. Selection is made for output channel
and scale factor. The parameter descriptions are the same as for
AC-3 with the addition of the filter and output channels.
User Function
USER
The USER function passes eight bytes of parameters to a user
programmed function that has been downloaded.
BCFG
Bass Redirection Configuration:
0 = No redirection, 1
= Redirect left and right to subwoofer, 2 & 3 = Reserved.
PRLG
Pro Logic output:
0 = Off, 1 = On, 2 & 3 = Reserved.
DE
De-Emphasis filter:
0 =Filter is disabled, 1 =Filter is
enabled, 2 = Filter is enabled if pre-emphasis is defined
in the MPEG stream.
OCFG
Output Speaker Configuration.
Number of Front/Sur-
round speakers. Valid configurations for MPEG only is
2/0 and MPEG + Pro Logic are OCFG = 3-7. 0 &
1 = Reserved, 2 = 2/0 Normal, 3 = 3/0, 4 = 2/1, 5 = 3/1,
6 = 2/2, 7 = 3/2. In 2/0 configurations, a mono input is
directed to both output channels.
