Source Names
Each video source in the switcher can be given a unique name.
Note: If a TSL ID is assigned to a source, the switcher overwrites the source name on the MultiViewer with the TSL name. If there is no TSL name, or it has not been received yet, the source name
is blank. For the labels on the MultiViewer, a combination of the TSL name and switcher source name are
used. The new TSL name is passed from the switcher to any downstream TSL devices.
