Information about Pixel Plus
Pixelplus, also called Pixel Plus, is a proprietary digital filter image processing technology developed by Philips which they claim "enhances" the display of analogue broadcast signals on their TVs.
Pixelplus interpolates 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 that may be unique to Pixelplus include motion interpolation, a processing technique that introduces (or reintroduces) a higher rate of motion into the video the TV is given. This can create an effect of 50 frames per second where 25 existed, or 60 where 30 existed, or 60 where 24 existed. Typically this is used for film-based material that was originally delivered in 24 or 25 frames per second, whereas the display is capable of far more fluid, realistic motion. Note that a broadcast may be 720p50 but still carry 720p25 material, for instance.
In 2005, Pixelplus 2 was launched. This version was the first to be able to perform motion reinterpolation on 480p and 576p material.
In 2006, Pixelplus 3 was launched. This version was the first to be able to perform motion reinterpolation on 720p and 1080i material.
In 2007, Pixel Perfect HD was launched. This version was the first to be able to perform motion reinterpolation on 1080p material.
There are now several webcams that have this technology. Its optics are so sensitive that it gives high definition images in the dark.

interpolation is a method of constructing new data points from a discrete set of known data points.
In engineering and science one often has a number of data points, as obtained by sampling or experiment, and tries to construct a function which closely fits those data points.

Frame rate, or frame frequency, is the measurement of the frequency (rate) at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems.

480p is the shorthand name for a video display resolution. The p stands for progressive scan, i.e. non-interlaced, while the 480 denotes a vertical resolution of 480 vertical scanning lines, usually with a horizontal resolution of 640 pixels and 4:3 aspect ratio
