Determining which video connector
you need
Check the Video Out port or ports on your video
equipment. A Video Out port should look like one of the
ports pictured below. (You may have both ports.)
To connect to a composite Video Out port, use a composite
(RCA plug) connector. See “Connecting Video Equipment If
You Use a Composite (RCA Plug) Connector.”
To connect to an S-video Video Out port, use an S-video
connector. See “Connecting Video Equipment If You Use an
S-video Connector,” later in this chapter.
