s video to VGA Adapter- Source and Display According to the Decoder
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.
This article contains basic information on the s-video to VGA converter box and is responsible for a series of specific questions that the sales often receives s video to VGA adapter.
