Cold open

A cold open in a television program is the technique of jumping directly into a story at the beginning or opening of the show, before the title sequence or opening credits are shown. The technique itself ancient; Horace gave it the Latin term "In media res" - "Into the middle things". Poems which use this technique inclued the Iliad, the Odyssey, and Paradise Lost. It is the opposite of ab initio - "from the beginning"

Cinematically, the cold open can last anywhere from less than a minute up to ten minutes (or more in rare circumstances). Several well known shows that begin with a "cold open" are Star Trek: The Next Generation, Star Trek: Deep Space Nine, Alias, X-Files, and Law & Order.
