9.3.3 ‘Follow Video’ Audio Channel Sources (DestThru)
There are 16 ‘follow video’ audio channel sources which are internal, virtual sources.
These are numbered 742 to 757, see the latter part of Table 63 in Appendix C on page 248.
The ‘follow video’ audio channel sources represent the embedded audio of the video source
specified in a pre-defined source or in a user-defined source. These sources are independent
of video crosspoint routing. As a result, ‘Follow video’ audio channel sources are used instead
of fixed source numbers in user-defined sources for many use cases. For example, where
embedded audio channels are subject to routing through the video crosspoint.
There is one ‘follow video’ source for each of the 16 embedded audio channels of the
corresponding video source signal, see Table 56.
9.3.4 ‘Follow Video’ versus ‘Fixed’ Audio Channel Sources
The behavior of the ‘follow video’ audio channel sources and the ‘fixed’ channel source
numbers is outlined here with an example.
Some user-defined sources are shown in Figure 122.

‘Follow video’ audio channel sources represent the embedded audio of the video source
specified in a pre-defined source, or in a user-defined source.
