Encoding Mode (MPEG-1 Layer 2)
The Encoding Mode parameter sets the operation mode of the MPEG-1 Layer 2 audio channel.
The available options are:
■
L,R Dual PIDs
– Encoding mode allows two different audio PIDs (elementary-streams) to be
transferred through the left and the right.
■
Mono (L only)
– Encoding mode is set to single, mono channel. Mono channel is always left.
■
Dual Mono
– Encoding mode allows two independent channels, carrying the same audio PIDs.
■
Stereo
– Encoding mode is set to stereo for encoding a stereophonic audio signal.
■
Joint Stereo
– Encoding mode is set to joint stereo. Joint stereo is used for more efficient
combined encoding of the left and right channels of a stereophonic audio signal.
The MPEG-1 Layer 2 Encoding mode default value is
Stereo
.
