Multichannel Analog Inputs

Some home theater receivers provide multichannel analog audio inputs, but these are rare in newer models.
If a home theater receiver has this option, it provides the flexibility to connect some DVD and Blu-ray Disc players
or another source component that may offer this as an output connection option.

Analog Video Inputs

There are three types of analog video input.

Component Video
This analog video connection option separates luminance (Y) and color (Pb, Pr or Cb, Cr) into three channels. It
requires three cables (colored red, green, and blue) to transfer video from a source device to a receiver or a TV.
Component video cables can transfer both standard and high-definition (up to 1080p) video signals. However,
most sources restrict signals from passing through component video cables to standard definition due to copy-
protection issues.

Composite Video
Composite video uses a single RCA connection (usually yellow, as illustrated in the photo example) to send
the color, B/W, and luminance portions of an analog video signal from a source device to a TV or home theater
receiver. Composite video signals are standard definition resolution analog signals.
S-Video
S-Video is another type of video connection you might find if you have or purchase an older used home theater
receiver.
The S-Video cable sends the B/W and color parts of the video signal through separate pins within a single cable
connector. This provides better color consistency and edge quality than the composite video option. It has been
superseded by both component and HDMI video connections.
