Channels as you need to find a way to transfer all that information through an agreed standard, in addition to the necessity to provide the manufacturers of boards and algorithms best offer to help the industry partners to provide the best we can.

And it found many ways to improve the quality of the image, such as UHD resolution, or what is known as 4K, which allowed more Alpesclat within the screen.

New technology that allows to improve the quality of the images displayed as they present a technique High Dynamic Range or what is known simply as HDR , which helps to produce the best quality Pesclat.

It could be argued that the HDR technology pose a real difference in detail between the past and the present, and the image details get lost in the scenes of the shadows and brightness when viewed by previous technologies.
