2 Composite Video Inputs
Th e SSP supports two composite video inputs, with RCA connectors
labeled 1 and 2. Use these inputs when the output of your source
component is composite.
A composite video signal (also called "baseband video" or "NTSC video")
combines the black & white and the color components of a video signal
and transmits them over a single cable. Composite video transmission
always generates interference between luminance and chrominance
portions of the signal and, for that reason, is usually inferior in quality to
the S-Video format.
3 Component Video Inputs
Th e SSP supports two component video inputs, each with three RCA
connectors labeled 1 and 2 – the component video format requires three
separate cables labeled Pr, Pb, and Y. Use these inputs when the output of
your source is component.
Although still analog, a component video signal provides a much sharper
image than S-Video or composite formats. Th e component video delivers
color video signals by maintaining the three YUV signal segments in three
separate channels. YUV is a video format defi nition which defi nes the
"color space", a mathematical model of the color within an image, of a
video signal. Y stands for luma (brightness), U for a color diff erence signal
(blue minus luma or B-Y), and V for second color diff erence signal (red
minus luma or R-Y). Th erefore, the three sections of the component signal
are Y (luminance – the black & white portion of the video), Pb (Blue
Color Diff erence), and Pr (Red Color Diff erence).
To connect the source component video output cables to the SSP
component video input rear panel connectors:
• Use the red cable for the Pr (Red Color Diff erence) connectors.
• Use the blue cable for the Pb (Blue Color Diff erence) connectors.
• Use the green cable for the Y (Luminance) connectors.
Th e SSP accepts component video at either standard defi nition (SD) or
high defi nition (HD) video rates. Component video is NOT accepted at
1080p via analog component connections.
NOTE: Although the SSP component inputs support all resolutions
except 1080p, some source material will be restricted to 480p at the
source.
