VGA/D-Sub: Practically every PC you've ever owned has a "VGA" or "D-Sub" connector. These two terms describe the same humble 15-pin monitor port still found on most laptops and desktops, and on many HDTVs. VGA cables can deliver a full HD video to your TV, though it may not look as good as it would over component or HDMI.

Video on demand: Video services that let you choose what you want to watch from a video library; you pay a small fee for downloads or streams.
