2016 Rio Olympics Opening Ceremony 7:30 p.m., NBC

If you’re planning to watch the opening ceremony to the 2016 Summer Olympics in Rio (or if you’ll be one of the millions who will unwittingly get sucked into watching it), don’t pull an NBC and forget: The official language is Portuguese, so (despite the network’s whiniest lobbying) the USA will be tucked in nice and early with the E’s (i.e. Estados Unidos). This year’s ceremony — helmed by filmmakers Fernando Meirelles (“City of God,’’ “The Constant Gardener’’), Daniela Thomas, and Andrucha Waddington — will star legendary Brazilian musicians Caetano Veloso and Gilberto Gil along with 5,500 others.

POV: My Way to Olympia 10 p.m., PBS

If you need a break from the 4½-hour cavalcade of champions (you will), switch over to PBS for this incisive POV documentary following the course of a group of athletes preparing for the 2012 Paralympic Games in London from director Niko von Glasow, who opens the film with a caveat: “Basically I think sports suck, and the Paralympics is a stupid idea.’’ As a disabled person himself, von Glasow’s skepticism makes for a far more profound examination of adversity than the average inspirational NBC cutaway.
