MPEG-2 Configuration
VBrick MPEG-2 Appliance Admin Guide 19
Configuration: Decoder > Audio
The audio selection provides for the control and configuration of the decoded audio stream.
Configure PID MPEG-2 transmits its data in packets of 188 bytes each. At the start of
each packet is a packet package identifier (or PID) that identifies the
data stream associated with that packet. Because the MPEG-2 data
stream might contain multiple video programs, the decoder has to
choose a particular video channel to play. The PID selection provides
that feature. If the user selects the automatic option, the first video
PID identified will be used to select the video channel.
Actual PID Actual PID being played. This read-only parameter is of interest when
the user selects automatic. A value of 8191 indicates the PID has not
yet been established.
Output Mode The audio output mode can be one of five possible setting as shown
below. Stereo directs the incoming left audio channel to the left
output, and the incoming right audio channel to the right output. Mix
combines the left and right audio channels and directs the combined
output to both the left and right audio channels. Left selects the input
left audio channel and sends it to both the left and right output
channels. Right selects the input right audio channel and sends it to
both the left and right output channels. Mute suppresses audio output.
The
Dual to
options are only operational on an input stream that was
encoded in
Dual
audio mode; otherwise, the Output Mode is
determined by the corresponding audio encoder setting.
