Connection Tips for Video Quality and Flexibility
The Emotiva DMC-1 has three types of video connections on board:
What is Composite Video?
Composite video signals are connected between products with a single 75-ohm coax cable
with Yellow RCA connectors on each end. Composite video inputs or outputs are present on
almost all types of consumer grade video equipment. Composite video signals can also be
modulated onto an RF carrier, along with an audio signal, and transmitted over-the-air or on
coax cable, by broadcast stations and cable TV systems. RF video signal cables are usually
75-ohm coax terminated with screw-on F-connectors. That's what your cable TV wiring is if
you have standard (non digital) cable services.
Picture Quality: Good. This is the lowest quality cable for a video source, but again, it is also
the most common.
What is S-Video?
Most midrange and premium video equipment provide the option of using S-video connec-
tions. The S-video (or Y/C) cable is terminated at each end with a four-pin DIN connector.
Although it may appear to be a single cable, internally it has two 75-ohm coax or twisted pair
cables to carry the separate Y (luminance) and C (chrominance) signals.
Picture Quality: Better. The S-video cable will offer marked improvement over a composite
cable.
What is Component Video?
Component cables look just like composite cables. The difference is that, where a composite
cable carries the entire video signal on a single cable, component cables split the signal in
three. The signal itself is referred to as either Y,Cr,Cb, or Y,Pb,Pr. Manufacturers make con-
necting these cables easy by color coordinating them. The tips of the cables and jacks will be
red, green and blue. A good rule of thumb is that, if the connections are RCA type, it is usually
a component cable. Most high-end DVD players and HDTV tuners will have component
connections.
Picture Quality: Best. This connection gives a superior image over Composite or S-Video
connections.
Video Up Conversion
The Emotiva DMC-1 has advanced video DSP circuitry and coding which allows the ultimate
flexibility in video signal processing. With these attributes, the DMC-1 can easily allow the
following:
a) Up conversion from Composite Video inputs to S-Video and Component Video outputs.
b) Up conversion from S-Video inputs to Component Video outputs.
c) Down conversion from S-Video inputs to the MON2 video output jack.
