LED video processor is already widely applied.

With the development of technology, there are various types of video processors on the market.

And each video processor has many functions and features so people do not know how to choose the right one.

This article is a brief introduction to the types of LED video processors, as well as to help you select the right product.

At the end of the article, we will recommend three top-rated products for your consideration.

Part One What is a LED video processor

1.what is a video wall?

A led wall is a special form of led display.

Multiple led displays are assembled together to create a larger screen, which called led wall,aiming to amplify the pictures or videos you need to play.

Industries that use video walls include corporations, hospitals, retailers, government offices, churches, schools, casinos, hotel receptions, etc.

2.What is a LED video processor?

(1)what is a LED video processor?

In short, the LED video processor is a dedicated processor for LED walls.

The task it needs to accomplish, in simple terms, is to convert the image signal from external (e.g. Blu-ray DVD, computer, HD player box, etc.) into a signal that can be accepted by the LED display.

(2)What can a processor do for you?

A. Image interception

Intercept a small area of the complete image and enlarge it to display it on the whole LED wall.

B.Image Magnification

zoom-in-pics

Enlarge the image and the maximum magnification is 10 times.

C. Image Overlay & Keying Composition


Overlay another signal on the screen to complete the function of adding subtitles, keying synthesis, etc.

D.Fade in and fade out

Fade-in and fade-out switching between two signal sources in 0 to 5 seconds.

E. Continuous switching

a. Switching between multiple signal sources can be realized.

b. It can realize fast switching between multiple application scenes.

F. Multi-camera connection

Synchronous tracking technology ensures the multi-screen picture and sound are complete and synchronized.

G. Synchronous tracking

Synchronous tracking technology ensures the multi-screen picture and sound are complete and synchronized.

(3)Where you can use a LED vide processor?

A.Exhibition

When the LED display is used indoors, people can see the content on the LED display in a close distance.

Like some museums display of cultural relics, airports, hotel lobbies and other information on public signs, which requires LED display screen brightness can not be too high.

The video processor is supposed to adjust the image to ensure that the LED display can softly output in the indoor light environment, achieve clear and layered effect, and accurately convey the broadcast content.

B.Business & Education

When you are in a confined space, such as in a classroom or conference room.

The size of LED displays is often not too large, and images need to be compressed first before play.

This is where a video processor is needed to process the picture details for you while compressing the picture, increasing the output capability and displaying the picture in as high a definition as possible.

C.Traditional Applications

When the LED display is used as a display screen for monitoring and control, this requires a large screen with high definition and many input signals.

And it can carry real-time images, as well as can be flexibly manipulated and managed.

That’s where the video processor comes to help.

Part Two How to choose the right LED video processor?

1. What kind of LED video processor is there?

(1)Kinds of video processor

This type of video processor has existed for the longest time.

They consist of multiple video processing chips with a single function.

Normally operated by remote control.


This type of video processor has the latest technology and can be operated and controlled by PC and Wi-Fi.

As a result, they are rich in features and their usability is greatly improved.

(2)Pros&Cons

a.Advantages
Hardware-based processors are generally more reliable.

The one-use application can bring almost zero failure rate.

b.Disadvantages
Hardware-based processors are more expensive.

In addition, it is somewhat inflexible in the present situation where the requirements for LED walls are diverse.

a.Advantages
more features, and there are many brands to choose from on the market.

b.Disadvantages
Most software-based processors cannot handle more displays or have high video input performance.

What’s more, you may be exposed to Windows virus risks, system crashes and blue screen crashes.

Software-based processors also require a certain level of expertise in programming and installation.

2.How to choose the right LED video processor?

1. Principle of choosing video processor

✓Stability

Dropped frames and freezing are issues that need to be avoided as much as possible.

A video processor that is unstable will distract the user and affect the playback of the content.

✓Accuracy

Accuracy is a basic requirement.

If the picture distortion occurs, it will not only seriously affect the viewing experience, but also may convey misleading information.

✓Multiple input signal processing capability

There are usually many types of input signal sources, and the video processor must have a strong compatibility capability.

Different input signals, flexible layout to the led display to adapt to the requirements of different occasions.

✓ Forward-looking

When buying LED video processors, in addition to clarifying the current needs, but also to predict the potential future demand.

The higher the technology content of the product, the longer it tends to be used, the better it works.

✓Maintenance and installation

Maintenance and installation are costs that cannot be ignored.

If you do not know much about LED displays or video processors themselves, then it is recommended to buy those products that are easy to operate, convenient, and practical.

Besides, it is best to buy from a business with a high pre-sales and after-sales service attitude, to avoid subsequent problems in installation and maintenance, no one can help you solve in time.

2.Factors affecting choosing video processor

A.Loading capacity

The maximum output resolution of LED video processors is divided into three main levels, which can be selected according to your actual needs.

general: 1024X768,1280X1024,1440X900

HD: 1920X1080,2048X1152

Ultra-clear: 3840X1080,4096X1152,3840X2160,7680X1080

B. Format support

Common video signal formats include CVBS, DVI, VGA, YPbPr, S-Video, HDMI, SDI.

C. Image enhancement

Image enhancement function can be said to be the main function of the video processor and plays an important role in practical applications.

When selecting a processor, you should pay special attention to whether the video processor’s image capabilities are above the market average.

If there are special requirements, be sure to seek the help of a professional.

You can contact our online customer service for help, as we have a professional team for customers.

With the increased demand in the market, both LED displays and video processors are facing great opportunities and challenges.

D. Switching speed

A good video processor will not allow black screens to appear.

The current video processor signal switching mainly takes two ways, direct switching, fade in and fade out.

Some video processing supports multiple switching methods and is therefore more expensive.

Generally speaking the direct switching method is used more frequently and can be prioritized when purchasing.

E. Multi-screen mode

Currently, common video processors support dual-screen mode.

However, some scenarios require the use of three images, four images, or even more.

If you need to support more screens, the corresponding price will be more.

F.Brands

Choosing an established brand is definitely a wise choice.

Within the LED video processor industry, Novastar is definitely the best!

With high brand awareness and strict product quality control, you’ll be satisfied with it!
