THERE ARE A NUMBER OF DIFFERENT TYPES OF VIDEO INPUTS.
Which type you need depends on the
equipment you currently have or intend to purchase and whether or not you plan to use an external A/V
receiver that has video switching capability. For reference, the various video input types are listed below:
COMPOSITE
This is the good old fashion yellow connec-
tor. Composite is the lowest performance
video connection since all the information;
chroma (color), luminance (the brightness)
and sync (which tells the TV when to start
scanning each frame and line) are transmit-
ted over a single cable. Not only does all
this information interfere with each other,
but bandwidth is also quite limited, so it's
recommended to only use this option if you
have a very old legacy device such as an old
video camera. The composite connection
cannot support HD.
DVI
The digital interface predecessor to HDMI, DVI is
a fully digital video interface that transfers each
color separately over high speed transmission
paths. While the digital video signals of DVI are
compatible with HDMI, DVI does not carry sound.
DVI is generally used today for computer moni-
tors and some front screen projectors, but rarely
found on FPTVs with the advent of HDMI.
HDMI
This is the preferred method for connection to
a contemporary FPTV. As discussed above,
HDMI is a high performance digital audio and
video interface that only requires a single cable
for both types of signals. Virtually all new source
devices, DVD players, Blu-ray players, cable or
satellite set-top boxes and game consoles include
HDMI outputs.
S-VIDEO
This was the first attempt to improve on
the composite connection by separating
the chroma and luminance signals
thereby reducing some of the interfer-
ence mentioned above. While it was an
improvement over composite, it still was
not very good and cannot support HD.
Use it if you must for those older analog
video devices.
COMPONENT
This was the first interface that used separate
cables for each of the primary colors, eliminat-
ing the artifacts of composite and S-Video.
Component is an analog interface capable of
supporting HD.
