Digital filter
In electronics, computer science and mathematics, a digital filter is a system that performs mathematical operations on a sampled, discrete-time signal to reduce or enhance certain aspects of that signal. This is in contrast to the other major type of electronic filter, the analog filter, which is...

 the broadcast signal to increase the picture size by one third, from 625 lines to 833 lines. It also doubles the horizontal resolution, although each horizontal line is analogue.

Other features include motion interpolation, a processing technique that interpolates (or creates) video fields (or frames) by analyzing fields (or frames) before and after the insertion point. This process is primarily focused on film based content which is filmed in either 24fps or 25fps. The motion interpolation function of Pixel Plus is an alternative to 3:2 pulldown processing with is the standard process of converting film to video.

In 2005, Pixelplus 2 was launched. This version was the first to be able to perform motion reinterpolation on 480p
480p
480p is the shorthand name for a video display resolution. The p stands for progressive scan, i.e. non-interlaced. The 480 denotes a vertical resolution of 480 pixel high vertically scanning lines, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio or a horizontal resolution of...
