Composite video signal is an all-in-one video signal, with everything
you need to create color images are combined into a single complex
signal. Composite video contains the following components:
imageintensity / brightness (grayscale), color, and sync pulses. Thanks
to the combination of all these signalsmakes it convenient for a single
road or forward, as only one cable is needed. However, the composite
signal is ultimately requires decoding before being displayed. Decoding
process can cause loss of signal quality.
Since the signal quality is compromised during the conversion and
composite video, it is best to use video in one of its components in the
band sooner if possible.composite s-video to vga converter box is one
of these components before. At this point, the color information is not
combined with information on the gray scale and the signal is easier to
process in video processing and display. In general, if the system
components can be connected to s-video to VGA converter instead of
composite, S-video should be chosen (see the exceptions to the FAQ
section below). Distribution of tools, composite video should be avoided
if possible; a high level of signal quality is the goal.
S-video to VGA converter contains the same information as a composite
video signal, but it is established that two distinct elements. The
luminance signal contains the brightness, intensity and timing
information of the signal. This is essentially all the information of
the image with the exception of color information. In fact, you can see
the whole picture in black and white, without the chroma, by feeding the
luminance signal in a monitor. Chrominance signal contains only the
color information. The process of converting composite video baseband
components is called decoding. The first part of the decoder used
composite s-video to VGA converter box. This first part is a specialized
filter that separates the composite signal in luma and chroma
components.
Filtering is complex and not perfect. A low signal crossover between
the chroma and luminance signals occurs during the filtering process.
This results in image artifacts that degrade the image. The quality of
this filter is very important. If any equipment used for decoding is of
poor quality, resulting from S-video will probably be better if the
composite video is used instead.
Most of all VGA sources, such as laser scanners and VGA have a
decoder to convert the recorded signal to the S-video output. Virtually
all medium to high-end monitors have an S-video and composite video
inputs. You choose to use either the composite s-video to VGA converter
box that source and display according to the decoder is better.
