VIDEO CONNECTIONS

Composite Video
Analog 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.
Analog Picture Quality: Poor. This is the lowest quality discrete cable for video sources and is not recommended if a
better quality connection exists.
S-Video
Most midrange and premium video equipment provide the option of using S-video connections. 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. This is also
an analog video signal.
Analog Picture Quality: Fair. The S-video cable is an improvement over a Composite cable but still not recommended if
a better quality connection exists.
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 to three cables. The signal itself is referred to as either
Y, Cr, Cb or Y, Pb, Pr. Manufacturers make connecting 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 analog component video connections.
Analog Picture Quality: Good. Gives a superior image over Composite or S-Video connections.
HDMI
HDMI (High-Definition Multimedia Interface) is an uncompressed, all-digital audio/video interface in a single cable.
HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It
transmits all ATSC HDTV standards and supports 8-channel, 192kHz uncompressed digital audio and all currently
available compressed and uncompressed formats (such as Dolby Digital, Dolby True HD, Digital Plus, PLIIx and DTS-HD
Master Audio, DTS-HD High Resolution Audio, DTS Digital Surround ES - Neo:6 - 92/24).
The HDMI section of the UMC-1 supports 480p 60Hz, 576p 50Hz, 720p 50Hz, 720p 60Hz, 1080i 50Hz, 1080i 60Hz, 1080p
50Hz, and 1080p 60Hz resolutions. The most common resolutions for the United States are 480, 720 and 1080 at 60Hz.
(50Hz resolutions are primarily used outside of the United States). The UMC-1 is fully PAL compliant.
HDMI offers the Best video resolution. Emotiva recommends using HDMI as the preferred connection.
