3: System Configuration
Channel Map/Source Control
SGI Media Server controls allow you to select what type of audio to route to each
MFCODEC input pair. The choices are embedded (E), AES/EBU (D), or analog (A). The
control, vtr.media.audio.input.channel_map.source, is set in the
/usr/vtr/config/device-defaults/MFCODEC_n file for the unit you want to
configure. This control, combined with the
vtr.media.audio.input.channel_map.channel_pair control, selects what
audio goes to each of the four MFCODEC input pairs . This can be changed on a
clip-by-clip basis.
The syntax for the vtr.media.audio.input.channel_map.source control is as
follows:
vtr.media.audio.input.channel_map.source value_0value_1value_2value_3
Each value_i variable represents the audio type for MFCODEC input pair i. The possible
values are E (embedded), D (AES/EBU), or A (analog). The following is an example:
vtr.media.audio.input.channel_map.source EEEA
Channel Map/Channel Pairs Control
The vtr.media.audio.input.channel_map.channel_pair control selects
which audio input of a particular type goes to each MFCODEC input pair. The choices
are 1, 2, 3, or 4 for embedded; 1, 2, or 3 for AES/EBU; or 1 for analog. This control,
combined with the vtr.media.audio.input.channel_map.source control,
selects what audio goes to each of the four MFCODEC input pairs . This can be changed
on a clip-by-clip basis.
The syntax for the vtr.media.audio.input.channel_map.channel_pair
control is as follows:
vtr.media.audio.input.channel_map.channel_pair src_0src_1src_2src_3
Each src_i variable represents the source choice for MFCODEC input pair i. The possible
values are 1 (source 1), 2 (source 2), 3 (source 3), and 4 (source 4). The following is an
example:
vtr.media.audio.input.channel_map.channel_pair 2314
