video signal hookup

In theory, the receiver acts as a collection device for multiple audio/video components, and typically has one connection to the TV, thus making it easier to switch between your several components while keeping your TV on only one input instead of switching inputs. If you have 5 video components connected directly to your TV, then you would need to change TV inputs for each component.

To answer your question: "If you hook your video into your receiver how do you get the video to your TV?" Well, as described above, your receiver will have typically one Video-Out connection that connects to your TV. If you have 5 DVD players plugged into your receiver, you still only have one video connection from your receiver to your TV. Today you would use HDMI cables do this legwork today since they carry both video and audio, thus eliminating the need of 5 wires when using Component. So, if you could connect 20 video devices to a receiver, the receiver does the switching between components and your TV stays on the same input.
