Hi jhasinski,
The tally from ATEM switcher is included in the Blackmagic Video Device Embedded Control Protocol [1] and is encoded into a SMPTE 291M packet in active region of VANC.
There are a number of ways to capture the VANC data:
1) With Blackmagic DeckLink Capture Card/UltraStudio and running custom application using DeckLink SDK to capture VANC data [2]
2) With Blackmagic 3G-SDI Arduino Shield with Arduino sketches to capture tally information [3]
Regards
Cameron
