This particular Simpson Strong-Tie video is part of the "Build a Stronger Deck" series which illustrates how to utilize Simpson Strong-Tie Deck Ledger Connections.

The deck ledger connection provides much of a deck’s strength.  At one end it supports the joists while also making the framing more rigid throughout.  The ledger is made of the same material as the rest of the framing which is usually pressure-treated lumber.  Builders will sometimes install the ledger first, before they lay out for the footings and dig the post holes. They then use the ledger as the main reference point for determining footing and posts for the rest of the framing.
