About track mapping
Figure 14-1. Output routing if no output channels have been assigned labels
If unique labels are assigned to audio tracks and output channels
If you assign unique labels to each of the tracks in a clip, and assign the same labels
to a corresponding output channel, the K2 Media Client routes each track exclusively
to its matching output channel. The following illustration shows one example of how
unique labels are evaluated.
Figure 14-2. Track mapping with unique labels
If language groups are used
You can have multiple tracks and output channels with the same label. If multiple
tracks have the same label, the K2 Media Client evaluates where to map the tracks as
follows:
• An output channel’s primary and secondary output labels are considered together
as a “language group” when assigning an audio track for playout. If two channels
have the same primary label but have different secondary labels, then those
channels have different language groups. For example, a channel with labels FRE
+ GER is considered a different language group than a channel with labels FRE +
ENG.
• Each output channel, in order from first to last, is evaluated to determine if the label
or language group matches a labeled audio track in the clip.The first channel with
a label or language group that matches the track label plays that audio track. If the
clip has several audio tracks with the same label, the first matching output channel
plays the first audio track, the second matching output channel plays the second
audio track, and so on.
• The Play Silence box. If the K2 Media Client does not find a matching label or
language group for the output channels, and the Play Silence box has been checked
in Configuration Manager, the channel plays silence. Otherwise, if the K2 Media
Client finds no match, the output channel plays the correspondingly numbered
audio track.
