Now that we have an image of the proposed TV mount...
I would suggest that you forget the Unistrut & L-brackets.
Simply cut three or four pieces of 3/4" plywood long enough to span
the joist bay
and wide enough to give you 2" or 3" of edge distance on your
mounting plate.
Glue and brad nail your plywood pieces together.
Fasten in the joist space with lags with properly sized pilot &
"clearance" holes.
Lags work better in wood as they eliminate hole slop.
As T4 mentioned, your per fastener loads are very low.
Even if the TV & mount weight is double or more, the loads are still
low.
Convince yourself of the strength of lags......
drill into the side or bottom of a joist, install a Simpson flat sheet
metal connector with a 1/4 or 5/16 lag, loop a piece of 3/8" nylon
rope through the connector & make a stirrup at hangs about 6" off the
floor. Slowly apply your weight.... you will see that a single lag
will easily support a man's weight.
