What is HD?

It is an abbreviation of the English expression “High Definition” defining a high resolution image. HD TV means uncompromising image quality. 

HD is a big leap forward compared to the standard SD TV (Standard Definition). Higher resolution means more pixels on the TV screen, so the picture is several times more detailed and sharper. 

At standard resolution, the screen displays 576 horizontal lines, while for HD, this amount is up to 1080 lines. 

PolBox.TV does not compromise — each HD channel is emitted in the best quality the signal sender gives us. Some channels may have bitrates of 20 Mbps! 

What is the difference between SD and HD image quality?

 

The illustrations show a magnified section of the image displayed with an accuracy of (from left) 480, 720 and 1080 lines. You will notice that the HD image contains much more detail. 

After this demonstration, it is hard not to see DVD material as inferior, offering a blurred image. 

A full HD picture contains five times more pixels than video on DVD. This allows you to show much more detail than a normal film. 

To watch these channels, you need stable Internet from 8–10 Mbps. 

By connecting a device with a LAN cable, you can improve the stability of the connection.
