The “S-Video” term can be also known as “Y/C” or “separate video”, being a signaling standard for standard definition video (usually 576i or 480i). By separating both coloring and black-and-white signals, any “S-Video” can achieve much better image quality to compare to the composite video. Nevertheless, any “S-Video” is well-known for having a lower color resolution to compare to the component ones.

There is a standard analog which the television signals go through. It is known to be going through a few processing steps on its way to being broadcast. Each of the mentioned can discard the information, lowering the quality of the final images.

The image should be originally captured in RGB form. After, it gets processed into three signals — the “YPbPr” ones: the first one is called “Y”. It may be created from all three original signals that are based on a formula that produces the needed brightness of the image called “luma”. The mentioned signal is known to be closely matching a traditional black-and-white television signal. The so-called “Y/C” method of encoding was a key that could have led to the backward compatibility. Once such “Y” signal is produced, it is subtracted from the blue signal to produce “Pb”. It also gets subtracted from the red signal in order to produce Pr.

If there is a need in recovering the original RGB information for display, the signals can be mixed with the Y for producing the original red and blue, and then the sum of the mentioned can get mixed with the Y in order to recover the green.

Any signal that has three components is not as easy to broadcast if to compare it to the original three-signal RGB. That is why the additional processing is always required. The first step is to combine the Pr and Pb in order to form another, the “C” signal. It is a usual procedure to achieve the chrominance.

Both amplitude and phase of the signal are what the two original signals represent. The mentioned signal can be bandwidth-limited after for complying with the requirements for broadcasting. The resulting C and Y signals can be after mixed together for producing the composite video. If you want to play back some composite video, then you have to separate both the “Y” and “C” signals which may be and difficult to do without adding any artifacts.

Each of the described steps may still lead to the unavoidable or deliberate loss of the quality. In order to retain it in the final image, it is better to eliminate as many of the decoding/encoding steps as possible. “S-Video” is one of the approaches that can be used for solving this problem by eliminating the final mixing of C with Y as well as the subsequent separation itself at the so-called “playback time”.

Carrying video, the S-video cable may be using ground pairs (termed C and Y) and synchronized signal. The luma signal is Y: it carries either or black-and-white or luminance of the picture, including the synchronization pulses. At the same time, C is known to be the so-called “chroma” signal, which carries the coloring-in or chrominance of the picture. The mentioned signal is known to be containing both the hue and the saturation of the video.

Any luminance signal is known to be carrying both vertical and horizontal sync pulses in the same way as a composite video signal. Luma is what a signal that is responsible for carrying the luminance after gamma correction called. In case you wonder why Luma is termed "Y", the answer is the following: it is simply similar to the lower-case Greek letter gamma.

In any composite video, the signals can co-exist on completely different frequencies. In order to achieve such effect, the luminance signal must be low-pass filtered. I should happen while dulling the images. S-Video is what can maintain two signals as separate ones. This detrimental low-pass filtering is not that necessary for luminance, but the chrominance signal still has some limited bandwidth that is relative to the component video.

To compare it with component video, which separates the color-difference signals into Cr/Pr and Cb/Pb while carrying the identical luminance signal, the color resolution of S-Video can be limited by the modulation on a subcarrier frequency of 3.57 to 4.43 megahertz. It all depends on the standard. It is also very important to know that this difference is simply meaningless on the home videotape systems. The reason for such statement is: the chrominance is already constrained by Betamax and VHS.

Carrying any color information in a way of one signal means that this color has to be encoded, usually in accord with PAL, SECAM, or NTSC, but it all depends on the applicable local standard.

S-Video also is known to be suffering from the so-called “low color” resolution. NTSC S-Video color resolution is 250 lines horizontal versus 120 lines horizontal for the Rec. 601-encoded signal of a DVD.

That may be a reason why S-Video is not as common in many European Union countries. Another reason may be the dominance of SCART connectors, which can be found on the most existing televisions. It is always possible to output any S-Video over SCART for a player, but televisions' SCART connectors are not always wired enough in order to accept it. In case they are not, then their displays can show only the monochrome images. To solve this problem, it is possible to modify the SCART adapter cable in order to make it work.

Program Evaluation and Review Technique (PERT) with ConceptDraw DIAGRAM  →

Big and complex projects sometimes need some simplification of plans and schedules. That's why Program Evaluation and Review Technique was invented and first implemented in 1958. You can create PERT diagrams effortlessly with ConceptDraw DIAGRAM and share them with your colleagues. Program Evaluation Review Technique (PERT) is a method that is used to assess and analyze projects. PERT is a valuable tool for the project management practice. PERT gives an assessment and analysis of the time needed to the project completion. A PERT chart is a visual tool that delivers a graphical view of a project timeline. It is used to display the sequences and dependences of project tasks necessary to complete a project. ConceptDraw DIAGRAM delivers the possibility to build a PERT along with other diagrams applied to assist management process by using its Seven Management and Planning Tools solution.Program Evaluation and Review Technique <br>(PERT) with ConceptDraw DIAGRAM  *

How To Create Restaurant Floor Plan in Minutes →

As restaurant industry is growing rapidly nowadays, researches show that almost half of the adults have worked in a restaurant or a cafe. Moreover, many of them dream to start their own someday. Unfortunately, it takes a lot of time to write a business plan and to find a great location, although some know how to create a restaurant floor plan in minutes or how to plan budget effortlessly. Hiring employees can also cause a lot of headache, but this is crucial for further success, because every guest comes to restaurant for a good service and delicious food. It is also worth noting that restaurant concept is also important, because it defines target audience and influences the menu. This diagram represents the floor plan of an ongoing sports-theme establishment - restaurant, cafe, or other food service. A number of widescreen monitors installed along the perimeter provide visitors the opportunity to follow the course of a match from anywhere in the dining room of restaurant or cafe. The most of sports fans believe that food and alcohol is a big part of any sports show. That is why the dining room takes the most space - almost 60% of the total establishment space. Nearly all sports fans consume beverages while watching sports - beer, soda or water at least. Thus, the restaurant floor plan designers added a large lavatory there. Moreover, project developers considered unnecessary the gender division of such delicate place - perhaps they guess that only men are watching football, or believe that alcohol will eliminate the most of gender differences.Restaurant Floor Plan
