Component: TV_Mon_Select_PKG
Description
This component was designed for Wood Norton Studio C where some instant switching of SDI video to monitors is required (ie no TAKE button used). It is used for the sound lip-sync selection panel and the vision control precision monitor position. Multiple components may be placed on a single user panel. At run-time the user taps the icon of the monitor to make that the active control destination. This is indicated by a narrow colour border around the monitor icon. The active and inactive colours are set by statesheets chosen by the panel designer. When a component is selected, it sends a message to it's host that can be forwarded to other components causing them to deselect their active operation state.
This version of the component uses the Wood Norton package selection which has two extra BNCS driver database sets. Driver database set 1 holds the logical names for each source and destination package, database set 2 holds comma delimited strings for each logical destination. The first entry in the list is the video crosspoint id, the second entry is the analogue audio crosspoint id, and the third entry is the digital (AES) audio router in the Studer OnAir 3000 audio desk. Where no crosspoint is required a '-' (minus) letter is present.
The component size 152 x 166 pels.

There is an equivalent component TV_Mon_Select that works with the SDI source selector rather than the package selector.
