It is pretty simple.
Broadcast decks are usually linked to whole studio sync generator i.e. genlock.
You now simulate this with pal out as you have only one deck and output. In big studio
where you have a lot of different machines you have to keep them in sync that picture
would not "jump". As you only have 2 devices you can simulate sync like this.
This method has downside also. When you do not have any thing coming out from
pal you lose sync. Once you play out something you will be fine.
