Understanding video connections
Your receiver has two types of standard video connections. You should use the
best connection available to get the best display. For example, if your VCR
supports an S-video connection, connect the VCR to your receiver using S-video
instead of composite video.
Connection
Quality Cable and Connector Description
Good Composite. The video signal is carried
through a single “pin.” This connection
method is the one that is most commonly
found on devices.
Better S-Video. The video signal issplit intotwo
signals, black-and-white and color. Text
