Understanding the History of Video Processing

by Thomas Rivera

Video processing refers to a signal process commonly used for entertainment. An image that employs various video filters where there are an input and output signal is used. Video files and streams can also be used equally. Additional devices used to process videos include codecs, scalers, and DVDs, among others. For instance, commonly used designs and video processing are different in television sets manufactured by different professionals. Video processors with a pixel loading capacity 3840*1920 can be used to:

Deinterlacing

Video sources, such as DVDs and standard definitions, can transmit interlaced images. Rather than transmitting every frame in a progressive scan, video sources often transmit half of the whole image in every frame at a specific time.

The same concept applies to image recording, where video cameras record half the content at a time. A video processor can be used to deinterlace a video in that it is turned into a non-interlaced form. Interlaced videos can be found in older-generation television and digital TV.

Commonly found in DVD titles, too, an interlaced video frame comes with two sets of fields arranged in a sequence. The first one has odd lines of an image while the second one has even lines. An analogue television uses this technique since it allows for lesser transmission bandwidth. At the same time, the technique keeps a higher frame rate for a life-like motion.

Frame rate conversion

Video processing can also be used in frame rate conversion where there is a need to provide a solution to motion blur coming from the generation of frames. In that context, motion blur is stimulated by adding a total of new frames to the older ones and finding the sum. You will realize that the problems you should solve are the same in many ways. 

Detail enhancement

Sometimes, the performance of an IR scanning system is classified by its ability to detect a range. This is sensible for security and surveillance systems provided that the user knows how far they will be capable of seeing an object. It can be challenging to detect the targets even if they are within the recommended range. 

A factor that has always been neglected is the problem caused by a high dynamic range. A video processor can be used to enhance such details to increase the time needed for detection.

Motion compensation

Motion compensation is useful in video compression since it can exploit a high temporal correlation between frames in an imaging sequence. Video compression plays a crucial role in multimedia applications. Inside a digitized video is a redundancy. Compression can be achieved by exploiting these redundancies. 

Final Thoughts

Do you want to convert low-resolution images into high-resolution images using a video processor? Well, the process should not be complicated if you understand what it takes to accomplish that. To convert a video signal into a resolution using a fixed pixel, a manufacturer needs to incorporate a video processing display chip. Besides scaling an image to fit into the resolution, a processor is designed to help remove artifacts caused by a video’s conversion.
